Eloise PretoriusFurther to the climate and energy challenges, animal diseases also affected the province and rapid response to the avian influenza outbreak as well as preventing foot and mouth disease kept our veterinarians on their toes.
We are fast approaching the end of the year and are past the halfway mark. As the year continues, climate change is affecting the agricultural sector in many ways, and it requires the sector to invest more in resilience rather than response. We cannot continue to respond to the impacts of climate change – we need a paradigm shift whereby our programmes and initiatives aim to invest in mitigation, adaptation and risk reduction.
The winter season is characterised by extreme weather conditions. The Western Cape, or Cape of Storms, has experienced severe floods recently that impacted the agricultural sector significantly with damages and losses exceeding R1 billion.
Loadshedding has also affected the economy and those most vulnerable, especially our agriworkers. In response to the prolonged electricity disruptions, the Western Cape Department of Agriculture hosted a successful Energy Summit whereby the private sector, organised agriculture and key stakeholders were able to advice on potential solutions/ interventions to the energy crisis. We believe that an integrated and multi-sectoral approach is required to respond to these complex issues.
Winter also reminds us that we are approaching a new season. If you have been experiencing a “winter season” in your life, in your relationship, in your family or in your career, just remember, “it is only a season”. The past season must not make us bitter – it must make us better. Let us continue to serve our citizens selflessly with dignity, passion and compassion. We are not just ordinary public servants; we are called to be extraordinary leaders in agriculture.
May the NEW season ahead of us be the dawn of “A NEW DAY”… a new beginning and a time of refreshing. May your hope be restored, your faith be renewed and may the joy of the Lord be your strength.
Let us aim to be the best we can be in the current and the future seasons. Let us all join hands to take agriculture to the next level and let us never forget that it’s not about us but it’s about the people of the Western Cape.
The quote that inspired me from a very young age has become my motto over the years: “Good, better, best… never be at rest until your good is better and your better best.”

The Western Cape exported approximately R1.6 billion worth of citrus to the US under the preferential market access offered by AGOA in 2022. This equates to 102 000 tonnes of highquality citrus and has created 35 000 jobs across the logistics value chain. Over the past few months concerns about South Africa’s potential loss of its AGOA eligibility were regularly expressed. What is AGOA and what is the potential impact on the Western Cape agricultural sector? Read all about it on page 30.

TThe Western Cape’s Growth for Jobs (G4J) Strategy imagines a 2035 where our economy is growing at between 4% and 6%. Where we are creating hundreds of thousands of new jobs, lifting people out of poverty. Where businesses, big, small and informal, have the energy, water, infrastructure, skills and technology to grow and succeed. Where a child, no matter where they are born, has the pathway to a better life.
To realise the goals of our G4Js Strategy we must harness every opportunity and advantage we can negotiate with existing and potential trading partners. A key trading partner for South Africa is the US.
Trade with the US is facilitated by the US African Growth and Opportunity Act (AGOA), which comes up for renewal in 2025. AGOA offers eligible African countries south of the Sahara duty-free access to the US market for more than 1 800 products. This is in addition to the more than 5 000 products that are eligible for duty-free access under the General System of Preferences programme.

In 2022, South Africa’s top exported agricultural products to the USA in value terms based on the selected products were worth R8.2 billion. At the top of the list were macadamia nuts and oranges, each accounting for 12.3% and 11.8% respectively of the total export value.
These are followed by mandarins (11.8%), wine of grapes [in containers holding 2 litre or less] (8.1%), edible ice cream (4.9%) and dried grapes (2.1%). Most of these products are produced in the Western Cape Province. The Republic of South Africa exported oranges worth R83 million to the USA in 2022, and have increased by an annual average growth rate of 16% in the past three years.
The agricultural sector is reliant on technology from the USA.
American suppliers in South Africa provide tractors, harvesters, drone technology, balers, planters, precision farming equipment and technologies, sprayers, irrigation, storage facilities, soil testing equipment and parts, and service facilities.
Companies such as John Deere, Corteva, Pioneer, Bayer, Land O’ Lakes, CHS, PepsiCo, Walmart and many others sell all sorts of technology and purchase from South African farmers.

At first glance, some of the things you would notice about the new Chief Director: OSS is his tall frame, friendly smile and right after that, his infectious laughter. One thing is certain, Paul Rockman is definitely a people’s person, a perfect fit for the job at hand.
II taught for five years and then I went into the retail sector for about three years. While doing this I completed a Master’s in Public Administration. In 2000 I got an opportunity at the Provincial Government (DoTP) in their personnel directorate. Subsequent promotions led me back to the Department of Education, where I eventually worked as the Director in the Office of the HOD up until 2011. For
the past 12 years I worked at the Public Service Commission as Provincial Director until the opportunity at the Department of Agriculture presented itself. I remember thinking: “I hope it embraces me as much as I am ready to embrace it.”
What will your new position as Chief Director: OSS entail?
Paul: From HR to facilities, internships, archives and energy resilience. Like the Afrikaans saying goes: “Dis so wyd soos die Here se genade!”
I am excited about learning and to bring my skills and knowledge to bear in this new environment.
What would you like to achieve in your new capacity?
Paul: I wish to see a steady upward trajectory in terms of conditions that are conducive for staff to work effectively and to flourish.
How did your previous positions/ experience prepare you for your new position?
Paul: At the Department of Education, Safe Schools was part of my directorate, so I am quite familiar with multiple sites requiring rapid and quick infrastructure delivery, safety measures, and having to contend with all sorts of external risks. From a governance perspective, we need to be ethical in all that we do.
Anything else you would like to add?
Paul: There is such a direct correlation between what all our colleagues in WCDoA do and how this changes lives – I want to be part of this.
What is your favourite food? I like hot curry!
What are your hobbies?
I love music. I play the bassoon and clarinet and I love singing in the choir. If I were to turn back the clock and come back as a different person? I would be a fantastic pianist. What makes you happy?
My two boys, Timothy and Nicholas, make me happy. I laugh easily and are always up for a good laugh.
If you could master one new skill in an hour, what would it be?
Being a mechanic. This would save me a whole lot of money!
Which book are you reading at the moment?
Because my boys are at university and I am an involved parent, I am reading their books. So, at the moment it’s Max Weber’s Economy and Society. Favourite quote?
Be kind and respectful to everyone, no matter who they are.

1Western Cape Department of Agriculture, 2, 3, 4 GreenCape
(MIRs) at the Cape Town International Convention Centre. This event marked the second formal launch of the MIRs.
GreenCape’s team of experts presented key research findings tackling important topics, namely:
1 Sustainable agriculture
2 Water
3 Energy services
4 Large-scale renewable energy
Introduction
On 16 May 2023, GreenCape launched its Green Economy Market Intelligence Reports
5 Electric vehicles
These studies involved extensive consultation with the industry and
funding support from the South Africa UK Partnership for Accelerated Climate Transition (UKPACT), Friedrich Naumann Foundation for Freedom Sub-Saharan Africa and the Western Cape Department of Agriculture (WCDoA). The next section presents key highlights for the MIRs.
The 2023 MIRs are a valuable resource for the industry and provide important information on some of the sector’s cutting-edge best practices and technologies. “Agriculture is dependent on natural resources, which are finite and also vulnerable to climatic conditions, hence research contributing to improving the resilience of primary agriculture and agri-processing serves a critical role,” said Minister Ivan Meyer, Western Cape Department of Agriculture.
Trends in agricultural production show yield improvements because of favourable climatic conditions (e.g., rains) due to the El Niño phenomenon. However, the coming production season forecast much drier production conditions, which require a shift to more resilient production methods. The sustainable agriculture team of experts has honed into opportunities that speak to this phenomenon and highlighted new and attractive investment opportunities. This is specifically for investors who would like to invest in sustainable agriculture and for producers who are interested in market insights to learn where the sector is going.
The next section is a summary of some of the key findings.
“Research contributing to improving the resilience of primary agriculture and agri-processing serves a critical role.”
Regenerative agriculture: Regenerative agriculture (RA) is a holistic farm management concept that not only includes maintaining current soil health but also rehabilitating soil that has been degraded due to exploitative production practices. RA introduces a low-cost production system in the long run as the benefits of this farming technology result in a significant reduction of input costs.
Renewable energy applications: While renewable energy alternatives, such as solar PV systems, solar-powered irrigation systems and wind energy, have remained popular, there are other technologies that could have substantial potential in agriculture, particularly solar drying technology. Solar drying technology presents an exciting opportunity in agriculture, not only for greater benefits on farms but also as an environmentally sustainable method of reducing post-harvest losses in low- and middle-income countries. This technology has successfully penetrated markets in Asia and Africa, especially in countries such as India, China, Kenya and Burkina Faso.
South Africa’s agricultural sector is an untapped market for this technology.
This encompasses conservation agriculture and additional principles of living roots and animal integration for improved biodiversity and productivity.
Smart farming: Refers to the use of technology to inform where and how resources are dispensed on a farm. Farmers are starting to realise the benefit of investing in smart farming technologies, particularly in the face of the increasingly unpredictable impacts of climate change.
Other drivers of increased farmer interest have been the clear financial savings technology that suppliers have been able to demonstrate to farmers.
Circular agriculture: Anaerobic digestion (AD) technology can provide a solution to a growing number of issues in the agricultural sector, particularly energy security for both seasonal and continuous production; management of agricultural waste residues and wastewater; and replacement of chemical-based fertilisers with a nutrientrich soil enhancer.
A circular economy in agriculture can be more resource efficient and potentially more resilient than the traditional linear economy in instances where producers can use circularity to reimagine production systems that have greater cost savings, income diversification and increased profitability.
The upgrade of wastewater infrastructure in the public sector: R8.14 billion in investment is required to restore the wastewater treatment works (WTWs) in the country to a functional state. The eight metros make up R2.76 billion of the total investment required.
The various market opportunities are related to infrastructure refurbishment, repair, replacement, maintenance and expansion.
The beneficiation of public sector wastewater sludge: Landfilling of wastewater sludge costs metropolitan municipalities across South Africa an estimated R132 million per annum.
There are related market opportunities in wastewater sludge beneficiation, including handling, transportation and off-take agreements.
The implementation of renewable energy and energy efficiency interventions at public sector wastewater treatment works (WWTWs):
There are various market opportunities related to WWTWs, including the supply, installation and operation of energy efficient and renewable energy technologies.
The term energy services (ES) is used to describe three interrelated energy market segments in the South African energy space, namely small-scale embedded generation (SSEG) [encompassing system sizes <1 Megawatt peak (MWp)]; energy storage; and energy efficiency (EE). Rising electricity prices, energy insecurity, dropping technology costs, supportive energy policies and policy-related incentives prompt consumers to explore alternative energy options driving the growth of the ES market in SA and creating a thriving value chain.
A positive regulatory movement, investor sentiment and steady recovery in the key commercial, industrial and agricultural sectors have led to continued market growth in 2022.
The market is still expected to reach a total capacity of 10 gigawatts peak (GWp)
by 2035 at a market value of approximately R100 billion. This steady growth, which translates to the potential creation of approximately 1 250 jobs, is significant in the South African context, considering the ongoing need to reduce the current unemployment rate.
Energy services investment opportunities highlighted for 2023, are:
• Rooftop solar PV installations: 600900 Megawatt-hours (MWh) p/a, R7.5 billion p/a.
• Behind-the-meter storage: 250 MWh p/a, R2 billion p/a.
• Smart meters: 100 000 to 300 000 upgrade P/A, R1.2 –1.6 billion p/a. »
2019 to be approximately 500 MW per year. This has however already been exceeded in 2022. For example, the mining sector has reported a pipeline of renewable energy projects over 2 GW that could be brought on stream in 2022/23, with an estimated cost of between R30 billion and R40 billion.
The leading technology of interest is solar PV, alongside solar-diesel hybrid power projects or battery energy storage systems for overnight operations.
Local manufacturing of renewable energy components and systems: It is estimated that by 2030 approximately 14 million solar panels and approximately 3 600 wind turbines would be required to fulfil IRP 2019.
4
Public procurement of new generation capacity: This opportunity is related to any new renewable energy capacity generated by Independent Power Producers (IPPs) either being sold to the national utility (procured through the Renewable Independent Power Producer Programme (REIPPP)) or to public entities such as local municipalities.
The Integrated Resource Plan (IRP) stipulates the total market size for electricity generation needed to meet the country’s demand.
Private procurement of new generation capacity: The potential market size for this opportunity was approximated by the IRP
Annual production assumes 70-90% localisation of key components and 90% of the balance of the plant by 2030.
Wind turbines convert the kinetic energy of wind into electrical energy.

EEtlike jare gelede kom klop die legendariese hortoloog, alombekend as Oom Koos Lötter, aan die deur van dr. Ilse Trautmann, destyds Hoofdirekteur: Navorsing en Tegnologie Ontwikkelingsdienste van die Wes-Kaapse Departement van Landbou, met sy boeke Die Vy in Suid-Afrika en The Fig in South Africa (gepubliseer in 2014) en onderneem die Departement om hierdie boeke te herdruk en te versprei.
J. de V. Lötter was beter bekend as “Oom Koos” onder die menigte kollegas en studente wie se lewens hy tydens sy
23 jaar as dosent in die Departement van Hortologie aan Universiteit Stellenbosch geraak het.
Oom Koos is op 29 Oktober 2019 in die ouderdom van 92 jaar oorlede, net ’n paar maande nadat hy die eerste ontvanger van die Hortgro 1662-bedryfstoekenning was.
Oom Koos se vroeë navorsingswerk het ook navorsing oor enting en oorwerking ingesluit, en ’n boek getiteld Die beginsels van wondgenesing en oorwerk van vrugtebome het uit sy pen gevloei. Hierdie boek is egter nooit gepubliseer nie.
Dr. Ilse Trautmann, tans Adjunk-Direkteur Generaal van Landbounavorsing en Regulatoriese Dienste, het tydens die bekendstelling van die boek by die onlangse Hortgrotoekennings 2023 vertel hoe Oom
Koos die oorspronklike boek, wat hy self gedruk en gebind het, tydens die geleentheid in 2019 vir haar gegee het met die woorde: “Maak daarmee soos jy goed dink.”
Dr. Trautmann het die bedryf genader en daar is besluit om die boek by te werk en modern uit te lê met finansiering van die Departement. “Die skrywer Anna Mouton en bladuitlegkunstenaar Megan Merifield het uitstekende werk gedoen,” het dr. Trautmann gesê. “Die resultaat is ’n moderne handleiding in Engels en Afrikaans wat van groot waarde vir die bedryf gaan wees en steeds die grondslagnavorsing en praktiese beginsels van wondgenesing en oorwerk van vrugtebome aan die bedryf sal wys.”
Die boek fokus veral op bladwisselende en sommige immergroen vrugtebome in die Wes-Kaap. Produsente en ander
belangstellendes wat die boek wil bekom, kan info@hortgro.co.za nader.
Die Engelse weergawe is beskikbaar met die titel Principles of wound healing and top-working in fruit trees. Dit is gratis beskikbaar in elektroniese PDF-formaat.
Die PDFs van die boek is op die Departement se webwerf www.elsenburg. com beskikbaar by die volgende skakels:

OOver the last few months, the Western Cape Department of Agriculture’s Sustainable Cropping Research team has collaborated with our colleagues in the Eastern Cape on the aspects of canola production.
In the interim, the WCDoA donated a self-driven plot planter and wagon to the Eastern Cape Department so that trials could be planted in more areas in the province.
The research team in the Eastern Cape is looking into the possibility of establishing canola production in the province. During the initial visit in September 2022, we introduced the basics of canola crop production to our colleagues during a day of lectures in Mthatha. The day was attended by their research team, led by Dr Silwana, and possible local producers that were interested.
In March this year, we went to the Dohne Research Farm near Stutterheim to instruct the team there in the use of the planter and helped them lay out and plant their first trial.
During the visit, we invited the team to visit the Western Cape in April when we started planting our trials, which culminated in the team visiting the Riversdale trial site at the end of April.
We are looking forward to some great results in the near future and the WCDoA is proud to assist the Eastern Cape in establishing its canola industry. AP

HHigh pathogenicity avian influenza, commonly known as bird flu, has recently caused outbreaks on poultry farms in the Western Cape. These outbreaks have raised concerns among consumers about the safety of poultry products available for sale at supermarkets.
It is crucial to address these concerns and emphasise that poultry products remain safe for human consumption, provided proper handling and cooking protocols have been followed.
Avian influenza is a viral disease that primarily affects birds, including domestic poultry and wild birds, but rare cases of human infection can occur in people who have had close contact with infected birds by keeping or slaughtering poultry. No recorded case of avian influenza in people has been linked to eating poultry.
The World Health Organization states that properly cooked poultry products, including eggs, are safe for consumption even in areas experiencing avian influenza outbreaks. Additionally, the influenza virus is sensitive to heat and is thus destroyed by cooking.
In South Africa, chickens and eggs from farms infected with high pathogenicity avian influenza do not enter the human food chain due to strict biosecurity measures implemented by farmers and Veterinary Services. Routine clinical surveillance and disease testing is done on commercial poultry farms. When a farm is suspected to be infected, it is placed under quarantine, meaning no poultry or poultry products may leave the farm without the permission of the State Veterinarian. On confirmation of the disease, all affected chickens are promptly culled, and their carcasses destroyed to prevent the spread of the virus. All eggs, manure and bedding from infected farms are also destroyed under the supervision of Veterinary Services. These actions ensure that no poultry products from infected farms can be sold.
To further ensure the safety of poultry products, consumers should follow proper handling and cooking protocols. These include storing raw poultry separately from other foods, avoiding crosscontamination and practicing good hygiene by washing hands after handling raw poultry. Additionally, poultry should be cooked thoroughly, reaching an internal temperature of 75°C, to destroy any potential pathogens.
Read the Journal article, How high pathogenicity avian influenza evolved in wild birds in Southern Africa from 20172018 by Belinda M. Peyrot on page 69.

To protect themselves, backyard poultry keepers should implement biosecurity measures, including:
• Personal hygiene. Wash hands thoroughly with soap and water before and after handling poultry, their eggs or any equipment used in their care.
• Personal protective equipment (PPE). Wear dedicated PPE, including disposable gloves, protective clothing, eye protection, a good quality mask, such as an N95 or surgical mask, and boots or shoe covers. Protective clothing should be kept separate from regular attire to minimise cross-contamination. Regularly clean and disinfect the protective clothing to prevent the spread of any pathogens.
• Restricted access to poultry areas. Allow only essential visitors to the poultry area. These visitors should follow proper hygiene protocols, including handwashing and wearing protective clothing. Maintain a secure perimeter to prevent the entry of wild birds or other potential carriers of avian influenza. Keep feed and water sources clean and protected from contamination.
• Health surveillance. Be vigilant for any signs of illness, such as decreased appetite, respiratory distress or a sudden increase in mortality. Isolate any sick birds and report the signs to your local veterinarian or animal health technician immediately.
While outbreaks of high pathogenicity avian influenza have occurred in the Western Cape, it is essential to emphasise that poultry products for sale at supermarkets remain safe for human consumption. Adherence to proper handling and cooking protocols, as well as the strict safety regulations and monitoring in place, ensure the delivery of safe and wholesome poultry products to consumers.

The large group of winners at this years’ Service Excellence Awards did the Department proud.
IIn May 2023, the Western Cape Government (WCG) rolled out the red carpet in recognition of excellence in public service delivery at the much-awaited Service Excellence Awards (SEA).
After months of planning, a call for nominations, adjudication and vetting, nearly 350 qualifying WCG employees made it to the Century City Convention Centre in Cape Town in the hopes of being a recipient of this coveted award.
The SEA is an annual initiative within the WCG that promotes a citizen-centric culture, entrenches professionalism, as well as recognises and rewards excellence. The purpose is to entrench the WCG’s value of caring by appreciating and recognising employees in exemplary cases. This year the awards further explored a WCG recognition system that extends to WCG citizens and provincial municipalities for encouragement of service excellence.
Martin Luther King Jr. is quoted saying, “Life’s most persistent and urgent question is: What are you doing for others?”
With the multitude of jobs they are able to pursue, civil servants set themselves apart with their eagerness to want to help others and make a difference. As WCG employees, the goal is to work towards the betterment of our society – not just for today, but for generations to come. This is further driven by the WCG values.
At the event, WCG Director General, Dr Harry Malila, officially welcomed the exemplary employees and Premier Alan Winde delivered the keynote address and presented the winners with their awards.
The master of ceremonies for this year’s event was well-known local comedian and GoodHope FM sports presenter Dalin Oliver, while the Mujahid George Band kept the crowd entertained.
The Western Cape Department of Agriculture (WCDoA) walked away with the following awards for this year’s Service Excellence Awards:
Best Frontline Service Delivery (BFSD-E)
Bronze: Jody Wentzel, Sustainable Resource Use and Management.
Best Support Service Employee (BSS-E)
Bronze: Desiree Chinasamy-Dampies, Structured Agricultural Education and Training.
Best Public Service Innovator (BFSI-E)
Bronze: Arie Van Ravenswaay, Research and Technology Development Services.
Best Citizen Performance (BCP-I)
Gold: Annemarie Verwey, Rural Development.
Silver: Christo Peter Farao, Rural Development.
Bronze: Raymond Andrew Swartz, Rural Development.
Best Collaborative Programme/Project (WOSA/WOGA) (BCP-W)
Silver: Rural Development and Partners, Rural Development.
Best Public Service Innovation Team/ Project (BFSI-T)
Gold: GIS Innovation Team, Research and Technology Development Services.
In what can be defined as one of the highest recognitions to be bestowed upon a public servant in the WCG, the WCDoA is ecstatic to see so many of our colleagues bagging an award in most of the SEA categories.
The WCDoA is proud to be serving the agricultural sector in an effort to increase jobs and improve economic growth. In all the accolades received, we cannot forget the great collaborations with our stakeholders as we all share one vision, that of a sunrise sector for the Western Cape, #ForTheLoveOfAgriculture.

IIn 2000 the United States of America (USA) introduced the African Growth and Opportunity Act (AGOA), giving eligible Sub-Saharan countries duty-free access into the USA for 6 400 products. Although AGOA was initially intended to cover the period 2000 to 2008, it was later extended up to 2015. In 2015 it was extended for a further 10 years and is due to lapse in 2025.
It is important to note that AGOA is an Act of the USA Congress. As it is not a negotiated free trade agreement (FTA), it can be unilaterally amended by them at any time.
Another mechanism through which South Africa receives trade preferences is the generalised system of preferences (GSP). In 1974 the USA introduced the GSP, which reduces duties on thousands of products imported from 119 countries.
Although 661 agricultural products are eligible to receive duty-free access under AGOA, South Africa is currently
only using 44 of these. The total value of South Africa’s agricultural exports to the USA amounted to R9.3 billion in 2022,
of which fruit and nuts were the highest, followed by beverages and then vegetable preparations (see Table 1).
Source: Calculations by T. Morokong based on Quantec 2022 data.
From the same table it is also clear that South African products, from all sectors of the economy that receives AGOA preferences, increased by 146% over the same period. However, whereas 25% of South Africa’s exports receiving AGOA preferences in 2019 was from the agricultural sector, it declined to 14% in 2022. This decline is not due to a lack in export growth in the agricultural sector, but rather because export growth in other sectors grew faster than in agriculture.
This analysis shows that more than $3 billion of South African exports is at risk if we were to lose our AGOA preferences. In the case of the agricultural sector, this amounts to 67% of the R9,3 billion exported in 2022; or, in other words, R6,2 billion.
A cautionary comment is that it is not a fact that this total amount will be lost, but that the actual loss will be determined by the competitiveness of individual firms.

TTraditionally, the Western Cape Department of Agriculture (WCDoA), in partnership with Wesgro, the Department of the Premier (International Relations) and Mazars Cape Town (a leading international audit, tax and advisory firm) have commemorated Africa Day by convening an annual business seminar during May.
Africa Day is dedicated to celebrating and acknowledging the successes of the Organisation of African Unity (OAU, now the African Union) from its creation on 25 May 1963, in the fight against colonialism as well as the progress that Africa has made while reflecting upon the common challenges that the continent faces.
• Take ownership of Africa – write your own positive narrative to dispel global misconceptions about Africa.
• Africa Continental Free Trade Agreement must work to uplift the continent from poverty.
• Implement the CAADP compact.
• Implement Energy Mix.
• Support SMMES programmes that embed energy resilience in sectors.
• We need political will to implement agreed long-term strategies regardless of government in power.
• There must be consequence management for bad governance, maladministration and corruption.
The 2023 celebrations were aimed towards accelerating the implementation of the African Continental Free Trade Agreement to bring greater prosperity to the continent. In the Western Cape, invited guests included African Consular Generals, politicians and business communities (local and international). During the plenary session, the majority of participants made concerted efforts to showcase their countries’ unique selling points with respect to business offerings and prevailing socioeconomic opportunities.
Furthermore, WCDoA made the 2023 chapter of this celebration unique. It took a step further by hosting an extraordinary seminar with delegates from the Africa Network of Agricultural Policy Research Institutes (ANAPRI) at Elsenburg on 26 May 2023. Both events were officially opened by the WCDoA Head of Department, Dr Mogale Sebopetsa.
The Elsenburg seminar was attended by representatives from the Bureau for Food and Agriculture Policy (BFAP), Western Cape agriculture and agri-business leadership, WCDoA management and an ANAPRI delegation (led by Salomo Mbai, Director of Agricultural Trade Policy Institute at the Namibia University of Science and Technology). This was a unique opportunity to cross pollinate ideas and best practices, and foster dialogue on critical agricultural policy issues.
As an institution, the ANAPRI network draws its members from different countries on the African continent with diverse expertise and experiences in agricultural
policy analysis, research and practical solutions. It was no surprise that the Elsenburg conversation concentrated on advancing sustainable agricultural development, food security and economic prosperity in Africa. Dr Troskie (WCDoA) demonstrated how data from evaluations is utilised as an evidence bank to guide policy, resource mobilisation and allocation in the Department.
• Use data-based evidence to advance sustainable agriculture development agenda for food security and economic prosperity.
• Share data, strengthen outreach, seek validation, and jointly provide solutions to common challenges facing Africa.
• Build capacity of member states to deliver sustainable and highquality research for effective national and regional policy.
• Promote peer learning in the region.
• Provide real time data to influence governments policy and decisionmaking process.
• Support CAADP and Malabo domestication and policy influence through research.
• M&E should be embedded in the discourse – both theory and practice.
• Institutionalise this seminar – making it an annual event at the Western Cape Department of Agriculture.
ANAPRI disseminated information on studies done on fertiliser and soil health policies, unravelling the intricate components that shape farming practices and contribution towards agricultural productivity on the African continent. It further unpacked the dynamics and the interplay between policy objectives, implementation mechanisms and outcomes.
Throughout the discussions, the delegates not only unpacked the components of fertiliser production, uptake and policy, but also the broader political landscape at play – including the influence of funders and the need for conservation agriculture and climate change to be factored in.
This enabled participants to identify areas for improvement and innovation with a wider focus on sustainable agricultural development, inclusivity and environmental stewardship.
In the end, it was acknowledged that ANAPRI’s commitment towards agricultural policy research in Africa is a testament to their dedication to improving livelihoods, enhancing food security and promoting economic growth on the continent. Through its work, ANAPRI is empowering policymakers and agriculture stakeholders with the knowledge needed to navigate the complex policy landscape and create an enabling environment for sustainable agricultural development in Africa.
Dr Sebopetsa concluded the session by recommending the institutionalisation of this event as an annual learning exercise on the WCDoA calendar. All key stakeholders will be invited to attend in 2024 and the near future. As he put it, “Power lies in working together and Africa is a great, sleeping giant awaiting to be awakened – we have to learn and work from each other.”
It all started with a brief meeting of the HOD and ANAPRI Chairperson in Namibia a few years ago and the rest is now history. We are all on board. #ForTheLoveOfAgriculture.

TThe game auction industry impressed with an all-time record of 26 game auctions that took place during May 2023.
This is the highest number of game auctions in any month recorded for the industry – a strong indicator of the industry’s vitality and the internal healthy competition that is out there.
By end of May, more than 27 000 animals were successfully transacted on these auctions, resulting in a turnover of more than R323,9 million. A staggering 23% of all auctions (18) had a turnover of between R3 million and R4 million. Table 1 shows that the average turnover of Quarter 2 (even though not completed yet) is standing at a healthy R3,288 million per auction, which is the highest in the past five years.
Aside from the common springbok, there are three springbok colour variant trophies that have become popular to collect and collectively officially recognised as the ‘Springbok Grand Slam’ – they are black, white and copper springbok. Photos courtesy of Jules of the Karoo Safaris. Photos © Willem van Rooyen.
The average number of animals per auction sold (352) is slightly higher than that of previous years. The fact that some 92% of all animals available were sold, is another indicator of a healthy industry where trust in animal sales and genetics are so important. Percentage wise, live game auctions continued to increase (78,8% of all auctions) and
again this is a healthy indicator of the post COVID-19 normalisation of the economy.
When moving away from colour variants, sales show a positive bias towards impala, blesbok, blue wildebeest, gemsbok, springbok and kudu sales with eland and red hartebeest sales also showing strong growth in numbers transacted (Graph 1).
Colour variants continue to impress with their 12,4% share in sales, which is somewhat surprising as in some spheres there seems to be a market sentiment to move away from colour variants. However, clearly there is a demand for these species, thereby stimulating these transactions.
Discussions on species’ prices become extremely complicated and “dangerous” as one needs to compare apples with apples. However, when comparing males with each other, the percentages seem to indicate that
some sable antelope (Matetsi and Zambian) and buffalo (East African) as well as king and blue wildebeest bull prices increased well above those in the previous year. Graph 2 also shows that black springbok, white-flanked impala and Damara and Kalahari springbok rams realised healthy relative prices when compared to 2022.
Thank you again to all of the auction houses/ventures who share their results so diligently. Data is of the utmost importance in order to track progress and possible structural changes within any economic sector. Without reliable and timely data our decisions may be sub-optimal and poor decisions may be the result. AP

IIn April the Western Cape Department of Agriculture (WCDoA) hosted the Multistakeholder Dialogue on Climate Disaster Solutions in Vredendal. The Dialogue was a follow-up to the Drought Dialogue for the Agricultural Sector held in June 2016, which concluded with 32 jointly identified challenges, prioritised to five actionable points that were subsequently implemented.
The April 2023 Dialogue went beyond drought to cover all climate-related extremes
Specific objectives were to learn from the lessons of the past (post-2016), to revisit existing relief tools and resources, and to agree on forward planning for greater resilience.
and disasters across the Western Cape Province, aiming to “Move from relief to resilience and risk reduction”.
The two-day event brought together 81 government decision-makers at district and provincial level, with national-level officials, smallholder and commercial farmers and representatives of organised agriculture and industry-commodity organisations, conservation bodies, representatives of the banking sector, related agri-businesses and selected subject experts.
During his address to delegates, Western Cape Minister of Agriculture, Dr Ivan Meyer, highlighted that the Western Cape Government recently adopted a Climate Change Governance Framework. “The Western Cape Government will in the future be looking at the impact of climate change on its three strategic priorities, namely, jobs, safety and dignity, and wellbeing. By doing so, we are mainstreaming climate change in the business of the Western Cape Government,” Minister Meyer said.
“We are mainstreaming climate change in the business of the Western Cape Government.”
Financial losses led to producers taking more financial risks in the years after droughts. Farmers are not sharing losses to relevant entities. Challenge to obtain external investment and no sustainable financial bridging models.
Conservation agriculture (CA) showed the benefits of soil water retention and soil fertility, spreading risks, etc., so more producers started implementing CA. Diversification into other crops and livestock in these dryland production systems. Plant according to natural resources – plant smart! Adjusting and advancing farming practices.
Problematic laws and regulations (that impede disaster risk management)
Illegal dams. Water use authorisations, verification and validation. Illegal abstraction (from rivers and boreholes). Ineffective irrigation systems. Insufficient legal storage capacity. Some areas had dams but no water and others water and no dams –infrastructure. Over-allocation of resources. Infrastructure not maintained. Lack of strategic provincial water planning.
Disaster Management Act not making provision for perennial crops during drought.
Renewable power – alternative energy options. Efficient irrigation – technology has improved – AI/netting/mulching/innovations – irrigation efficiency (more production per litre of water), irrigation scheduling. Technology for irrigation has changed/ improved and seasonal amounts should take this into account.
Increased recycling of water/alternative water sources/ groundwater to augment surface water – same water cycle. Efficient water conservation. Build capacity in good years –assurance of supply and more storage. Increased measurement of usage (needs further improvement).
Using early warnings – seasonal outlook. Expansion of weather stations. Early-warning standard operating procedures. Forecasting and early warning. Focus on scientific data –evidence, monitor, sense-making.

On 24 April, 11 working groups discussed the risks, impacts and vulnerabilities of climate disasters in the Western Cape Province, as well as the negative lessons (challenges, barriers) learned since 2016 that must be turned into positive actions, and the positive lessons (successes) that should be further developed and scaled up.
On 25 April, the working groups reconvened to discuss the seven “negative to positive” themes and the nine “positive to scale up”
themes in more detail. The task was to choose the two most important themes from each group and to develop specific actions that are required for each.
The seven prioritised themes shown in Table 1 will be taken forward for further detailed discussion by task teams and developed into an Action Plan. AP

On 13 May 2023, Vusumzi Zwelendaba, Director: Food Security and the Agricultural Advisors from the Cape Metropole District, hosted presentations on sustainable food programmes and the benefits thereof –both for personal use as well as creating SMME opportunities. Vusumzi presented the various interventions coordinated and offered by the Western Cape Department of Agriculture (WCDoA) under the SubProgramme: Food Security (See Figure 1). Basically, the learners were encouraged to start food gardens to address food security.
These learners are involved in sports through cycling. They say a healthy body results in a healthy mind. The key to this is access to affordable and nutritious food. These learners are from disadvantaged
communities that are highly affected by food insecurity, hence there was a need to encourage them to start their own production of food. As sports people they need to eat healthy and nutritious food that might come at a price seeing the current economic conditions in our country.
Karel Abels and Gavilin Daries showed the learners how to establish a food garden at home or at school. Towards the end of the programme, the WCDoA donated seed packs to the learners. Each learner received three packets of different seeds, i.e. cabbages, carrots and green beans. This was to encourage them to start their own household food gardens. This is in line with our broad strategic interventions:
1 Household agricultural food production initiatives, e.g. vegetable garden, chicken and piggery production.
2 Subsistence farming through supporting community and school food gardens.
In addition to this, we expanded our footprint by partnering with a number of stakeholders, such as The Sports Trust, on the ground through our WCDoA Food Security Flagship Initiatives:
• One Home! One Garden!
• Nourish 2 Flourish Mobilisation.
• World Food Day (WFD) Initiatives.
• World Food Day School Competition.
• Food Garden Competition.
• Agri-Processing On Wheels.
As the WCDoA, we always ensure that we take our services to the people where they are. To us, food security is an integral part of the wellbeing of the people of the Western Cape. It is through this understanding that food symbolises so many things, i.e. Hope, Care, Wealth, Dignity, Strength and Love. One Home! One Garden! We leave no one behind! #ForTheLoveOfAgriculture

IIn 2001, the Food and Agriculture Organisation of the United Nations established a day exclusively to highlight the importance of milk as a global food and to celebrate the dairy industry. This year’s theme is how dairy is reducing its environmental footprint, while also providing nutritious foods and livelihoods.

This year, the Western Cape Department of Agriculture (WCDoA) chose to showcase World Milk Day to the future leaders and agriculturalists at JJ Rhode Primary School, a neighbouring school near Elsenburg.
“The annual World Milk Day provides the perfect opportunity to spread the word that milk is an integral part of a healthy, balanced diet and to express our gratitude to our milk producers, agri-workers and agri-businesses for working tirelessly to make milk accessible to our consumers,” said Dr Ivan Meyer, Western Cape Minister of Agriculture, in his keynote address.
The information session was nothing but fun and educational with the very engaging Grade R to 3 learners learning about the importance of a balanced diet, which includes milk and dairy products, where these delicious dairy treats come from, and the importance of cows. They were each given a cow mask in remembrance of the day.
Mooing outside were three beautiful Holstein cows. In a time when the youth are losing touch of where their food comes from, it was important for the WCDoA to have actual cows for the children to see, and
the animals formed an integral part of the learning and celebration. After all, what’s World Milk Day without the cows?
Marline Burger, an Animal Production Scientist, shared fun facts about dairy cows through her loudhailer, with the children getting an opportunity to ask questions.
Often known to be shy, these gentle beasts weren’t the least bit bothered by all the noisy activity around them, perhaps because they had some 100 masked cows staring back at them!
The day was concluded with delicious treats of yoghurts, drinking yoghurts and juice courtesy of Lancewood.
There were great expressions of delight and gratitude by the learners, with countless occasions throughout the day where one could hear and see sheer glee.
The World Food Prize winner Dr Verghese Kurien, known as the father of the white revolution of India, once said: “True development is not the development of land, or of cows; it is the development of men and women.” Through his entrepreneurial ideas and leadership with a particular focus on the skills development of women and youth, India became the world’s largest milk producer. This is a clear indication that we all need to take a moment to educate and invest in our future generation.

• While the number of producers in South Africa has declined by 46% from January 2015 to January 2022, milk production has increased by 7.2%. This indicates increased output per cow and more significant numbers of cows per producer.
• The Western Cape is home to 33% of the milk producers in South Africa. They are responsible for 30.6% or 1 041 349 tonnes of the country’s fresh milk production, followed by our sister coastal provinces of the Eastern Cape and KwaZulu-Natal.
• At an average, milk price at the farm gate of R7.50/kg, it equates to more than R7.81 billion in the province at the primary producer level alone.
• Of the more than 1 million tonnes of milk produced in the Western Cape, 62% is sold in liquid form as fresh, flavoured or long-life milk. The remaining 38% is processed into concentrated products, such as custard, yoghurt and a great variety of cheeses. As a result, dairy product value-add plays a significant role in sustainable job creation.

WWater, a vital resource for life, can also harbour disease-causing agents. A recent comprehensive study by the sub-programme of Veterinary Public Health between 2021 and 2022 has illuminated the water quality situation within abattoirs across the Western Cape. This initiative is part of Veterinary Services’ effort to improve public health, safeguard our food supply and aid abattoirs in their pursuit of excellence.
By measuring parameters such as total aerobic bacterial plate count (APC), total coliform count (TCC), faecal coliform count (FCC), E. coli count and faecal staphylococcal count (FSC), the study provides a comprehensive view of the water’s microbiological profile.
The study collected water samples from three critical points in all of the 62 abattoirs in the Western Cape over a full year:
1 The first sample was obtained from the water entering the abattoir establishment, from sources such as municipal inlets, boreholes, reservoirs or other applicable sources.
2 The second sample was taken from water sources used during the slaughter process in the abattoir production area.
3 The third sample was collected from water sources used for the final carcass wash before the carcasses entered the chillers.
The following five graphs summarise the results of our data collection. Each graph reflects the results of a type of test conducted on three separate samples taken at each abattoir as well as the applicable legal limits.

“The TCC is another indicator of water sanitation.”
“The FCC specifically indicates the risk of waterborne diseases.”
The APC provides an overall measure of bacterial presence but may not account for slow-growing anaerobic bacteria. While it is not highly specific, it does provide an indication of general water quality and the risk of waterborne diseases. The TCC is another indicator of water sanitation, as coliforms from soil, animal waste or human waste can contaminate the water source. The counts of Escherichia coli (E. coli) and faecal coliforms are included in the TCC. The FCC specifically indicates the risk of waterborne diseases caused by faecal coliforms, which can stem from sources like human sewage, agricultural runoff, storm effluent or inadequate water treatment. E. coli counts high-
light the presence of E. coli bacteria, while the FSC indicates the presence of staphylococci bacteria of faecal origin. Both types of bacteria can lead to severe food and waterborne illnesses.
Upon the identification of any concerns, the abattoirs were notified and assisted in taking immediate corrective actions to ensure improved water quality and meat safety in abattoirs.
By helping the abattoirs understand and reduce microbiological risks, it’s not just a matter of monitoring but actively improving the quality of water and subsequently, the health of our nation.

“FSC indicates the presence of staphylococci bacteria of faecal origin.”
For context, according to the VPN16/201703 standards for Microbiological Monitoring of Water, the acceptable limit for APC in water sources used in export-approved abattoirs is capped at 100 colony-forming units per millilitre (cfu/ml), a standard far stricter than the 1 000 cfu/ml APC limit for
While only 25.8% of the abattoirs fully met the required microbiological parameters at all three sampling points, this study’s insight has already resulted in notable improvements as corrective actions were taken. The importance of having access to potable water in abattoirs to ensure the production of safe products is undeniable. The data indicate there is significant potential for enhancing water quality in our abattoirs, which will inevitably lead to better meat safety and increased product shelflife. With the assistance of Veterinary Public Health, abattoir owners have the support and resources they need to ensure reliable potable water in their operations.
abattoirs catering to the local market set by SANS 241-1:2015 Edition 2 Drinking Water. This discrepancy sparks an important conversation about ensuring equally stringent standards for all abattoirs, and Veterinary Public Health is engaged in this dialogue and facilitating changes where needed.

CConsidering the impact of climate change on agriculture, along with the continuous growth in population and pressure to produce more food (FAO, 2015), the use of technology from the 4th Industrial Revolution (4IR), namely artificial intelligence (AI), the Internet of Things (IoT), Big Data, drones and other remote sensing tools, are becoming the norm (Du Preez, 2020). These technologies offer exciting opportunities for the agricultural sector that can

improve resource-use efficiency and productivity (Marucci et al., 2017).
Satellite-based remote sensing technologies offer a low-cost and scalable solution for monitoring irrigation water use (Serrat & Herrmann, 2019). FruitLook is a remote sensing tool specifically designed for the Western Cape agricultural sector, visualised through a web-based portal, www.fruitlook.co.za, that provides near real-time data based on remote sensing.
Water is a critical resource adversely affected by climate change. According to the Smart Agri brief for the deciduous fruit sector (Green Agri, 2023), a high probability of increased warming and reduced winter rainfall is predicted for the western parts of the Western Cape in the future –the regions in which high concentrations of key crops are produced.
Considering the essential requirement of rainfall and irrigation for the successful production of various crop types in the Western Cape, the efficient use of water by primary crop producers becomes a necessity for sustaining food production in an environment that is becoming increasingly complex and ever-changing.

iDeveloped by Dutch company eLEAF and fully funded by the Western Cape Department of Agriculture, FruitLook offers farmers, consultants and researchers an overview of the growth, water use and nitrogen status of any crop type. This extra layer of information unlocks the ability of a crop producer to track the effectiveness of their management decisions, thereby supporting them to produce more while using fewer resources.
The FruitLook user base was recently introduced to a new tool named the Water Balance Calculator (WBC). It is based on the water balance approach and allows a FruitLook user to estimate the irrigation needs of a field according to its actual evapotranspiration (ET) data, obtained via FruitLook, soil characteristics and the desired level of water stress. This tool aims to take irrigation monitoring via FruitLook’s remote sensed data to the next level.
The calculator was trialled by long-term FruitLook users before its release and was found to be extremely valuable to determine how much irrigation is sufficient to keep their crops stress-free under changing weather conditions. Mark Witney, an avocado producer from Loeriestroom Farm in Groot Brak, stated that “the most important part of the WBC is knowing how much water is available for my crop.”

The process of capturing information in the tool is simple, starting with the field details, such as crop, size, soil depth, irrigation efficiency, soil type, plant available water (PAW), initial soil water level (SWL), maximum deficit, Regulated Deficit Irrigation strategy and start date.
Thereafter, the user captures the ET, rainfall and irrigation applied. Based on the information provided, the tool will automatically calculate the current plant-available water, excess water and the recommended amount of irrigation required to replenish the soil profile of the field.
iLandsat Next is on the horizon

KKaroo plants that are poisonous to livestock have plagued farmers for centuries. In South Africa in 1775, nenta poisoning was first recognised as a disease entity in small livestock. It was later proven to be caused by plants from the genus Tylecodon (common name: nenta).
The most infamous of the poisonous plants in the Klein Karoo are the nentas/ kandelaarsbos and the plakkies. These include Tylecodon ventricosus (stone nenta), Tylecodon wallichii (krimpsiekkandelaar, which is also toxic to bird species) and Cotyledon species (commonly known as pigs ears or plakkies). Poisoning by bufadienolides (the toxic components in the plants) can be either acute or chronic, depending on whether there is a cumulative effect or not.
Members from three plant families are responsible for the majority of livestock poisoning cases in the Little Karoo. These are Crassulaceae (plakkies and nentas), Iridaceae (irises) and Colchicaceae (poison onion, chincherinchee). They contain alkaloids in their leaves, bulbs and flowers, and this is the source of their toxicity to livestock. Most of these plants occur abundantly in overstocked and overgrazed veld.
Acute poisoning occurs when hungry animals consume large quantities of plant material. This affects the respiratory, cardiovascular, gastrointestinal and nervous systems, and leads to death within one to three days or to recovery within a few days. Affected animals can be visibly sick –they lie down or are obviously in pain, and in both cases, there are signs of bloating. They exhibit salivation, lodging of food in the back of the throat and dribbling saliva.
Chronic (cumulative) poisoning, known as krimpsiekte, is more common and is also caused by the bufadienolides. Here the nervous system is mostly affected. Initially the animals swell up (opblaas) and display the characteristic pose of the feet together and back arched. The affected animals lie down frequently and develop paralysis. Goats often do not exhibit symptoms until they are driven or disturbed. Poisoned animals tire easily and get left behind. Symptoms of poisoning include shivering, staggering, muscular twitching, trembling of the lips, and in some cases, convulsions.
Animals dribble saliva, breathe rapidly and food may collect in the mouth, as they are unable to chew or swallow. Animals may die within a few days, but some recover if left undisturbed for some time. Poisoning can lead to abortions in pregnant ewes.
Recommended treatment includes 2g activated charcoal per kg body weight, mixed with water and stomach tubed. This is essential as the animals cannot swallow. The excessive stress caused by restraining and dosing the animal might induce fatal cardiac disturbances. After dosing, animals must be kept calm and rested in the shade, in a kraal or small paddock to minimise any further stress.
Prevention of poisoning is more effective, and this is done by transferring stock to camps that are free of nenta and plakkies, and by eradicating the plants from the camps. Supplementary feeding during droughts will help ensure that animals consume fewer plakkies. Nentas and plakkies are symptoms of heavily grazed and overgrazed veld, so grazing system management is key to reducing the number of plants in camps.
Cotyledon orbiculata (pig's ears), a common plakkie in the Klein Karoo region, has resulted in the fatal poisoning of ostriches in the Oudtshoorn area. Of the 90 ostriches in the camp, 25 died after eating the leaves of Cotyledon orbiculata. The birds died within five days of eating the plant.
The most common poisonous plant of the Iridaceae family is Morea polystachya, known colloquially as blue/poison morea, bloutulp and kraai-uintjie. The plant is 80cm high, with clusters of blue and yellow flowers on the tips of the branches. It typically flowers from March to May and occurs abundantly in overgrazed or poor condition veld. It is widespread throughout the country. Poisoning by Morea spp. and slangkop
(Drimia spp.) is usually acute intoxication as these species contain non-accumulative bufadienolides, so chronic poisoning does not occur. Drimia spp. more commonly occur in the northern parts of South Africa.
Chincherinchee (Ornithogalum spp.) poisoning can occur in many species, including people. Ingesting any part of the plant can cause severe diarrhoea, abdominal pain, convulsions and death. Poisoning in cattle also causes blindness.
The key to preventing poisoning of livestock by toxic plants is veld management and supplementary feeding during dry conditions.

Does shearing feedlot lambs improve profitability?

How high pathogenicity avian influenza evolved in wild birds in Southern Africa from 2017-2018

IIn traditional wool producing systems shearing is one of the most important actions to take place on-farm and therefore the timing and frequency thereof is regarded as a critically important part of the management program. As such, shearing programs are set up to allow for the production of as much wool of the desired quality as possible within a shearing cycle.
Contrastingly, in feedlots where the focus is exclusively on meat production, shearing is often regarded merely as an easy way to increase feedlot income. Sheep are shorn shortly before slaughter and the wool sold to help cover the running costs of the feedlot (Van der Merwe, 2020). This practice does not take into account the age of the animals or quality of wool produced. Since feedlots generally operate on very small margins, questions have been raised as to whether shearing practices could be adapted to help improve profitability.
Shearing an animal places it under considerable stress (Elvidge & Coop, 1974; Carcangiu et al., 2008; Sanger et al., 2011) which could lead to the alteration of certain physiological processes in the animal (Wodzicka-Tomaszewska, 1963; Carcangiu et al., 2008; Aleksiev, 2011; Alqaisi et al., 2020) or physical actions taken by the animal (Wodzicka-Tomaszewska, 1963; Minson & Ternouth, 1971; Avondo et al., 2000). This post-shearing stress is mainly due to the challenges faced by shorn sheep in adapting to their thermal environment. Sheep are able to adapt to
a wide range of thermal conditions due to the insulating properties of their fleeces, which creates a microclimate next to the skin (Aleksiev, 2008). Shearing of sheep is therefore always accompanied by some degree of thermal stress, regardless of the season (Wodzicka-Tomaszewska, 1963; Aleksiev, 2008). Once the fleece is no longer available to help regulate homeostasis in the sheep by controlling body temperature, other physiological and biochemical pathways are triggered to maintain a homeostatic balance (Aleksiev, 2011). The upregulation of these homeostatic pathways will increase the energy expenditure of the animal (Minson & Ternouth, 1971). The increased energy demands of the sheep can be fulfilled either by bodily reserves or by an external energy source (feed). This means that animals will either have increased feed requirements (Elvidge & Coop, 1974) or use body reserves (Wodzicka-Tomaszewska, 1963).
Generally studies have found that shearing increases feed intake in sheep. WodzickaTomaszewska (1963) found that two-tooth Romney wethers with ad libitum access to feed increased their digestible dry matter intake by approximately 50% after being shorn in winter. Another study showed that ewes grazing on cereal stubbles at the end of summer increased their dry matter intake when shorn (Avondo et al., 2000). A US study found that shearing feedlot lambs increased their feed intake over the finishing period (Lane & Kemp,
1990), while Çam et al. (2007) determined that shorn ram lambs increased their feed intake in winter. The same results were obtained by Keady & Hanrahan (2015) on crossbred Suffolk lambs during winter. However, two studies done by Aleksiev (2008, 2011) found that shearing did not increase feed intake in lactating ewes. The fact that both of these studies were done on lactating ewes may however have influenced the outcomes. Dabiri et al (1996) also reported that shearing did not increase intake in pregnant ewes. In this study intake may have been limited by the foetuses taking up space in the abdomen of the ewes. Mixed results were obtained in an Australian study when Merino wethers (initial weight ~ 41kg) were fed three different types of hay. These animals had eight months’ wool growth and were therefore older than average South African feedlot lambs. When compared to unshorn animals, shorn animals had a lower intake of lucerne hay, a higher intake of pangola hay and no difference in intake was found
for setaria hay (Minson & Ternouth, 1971). The authors concluded that the intake of poor-quality hay (pangola) could increase as a result of shearing.
Increasing feed intake without also improving growth rate would not be favourable in a feedlot situation and would in fact decrease profitability through higher feed costs. In the study of Çam et al. (2007), eight month old rams displayed increased growth rates after shearing during winter. However, no increase in ADG was displayed by the crossbred Suffolk lambs (initial weight 39kg) used in the study of Keady & Hanrahan (2015), while Lane & Kemp (1990) also reported no improvement in ADG for crossbred wethers (initial weight ~35kg) shorn in summer. Both of these studies therefore showed a decline in FCR (increase in FCR figures) of feedlot lambs after shearing.
Since shearing places sheep under thermal stress, the environmental temperature also plays a role in determining the response of the animal to shearing. Elvidge & Coop
(1974) found that, at 17⁰C, shorn sheep had an 18% increase in feed requirement when housed and 24% when exposed, when compared to unshorn sheep. At 7-10⁰C that increased to 46% when housed and 76-78% when exposed. Eight-month old rams were also found to increase their feed intake when shorn at an average temperature of 5.4⁰C (Çam et al., 2007). A study done in Ireland during winter concurs with these findings (Keady & Hanrahan, 2015) as does one performed in New Zealand (Wodzicka-Tomaszewska, 1963) It can therefore safely be assumed that shearing lambs during winter will increase their feed intake although no significant benefit in terms of growth rate or feed conversion will accompany this increase since the additional energy is used for homeostatic maintenance and not production (Aleksiev, 2011).
Exposing sheep to high ambient temperatures may lead to a decrease in feed intake and thus inhibit growth (Dikmen et al., 2011). Shearing lambs during warmer periods could therefore help to alleviate symptoms of heat stress (Herrig et al., 2006; Dikmen et al., 2011). Herrig et al. (2006) found that shearing lambs during summer improved ADG, although there were possible confounding factors that could have influenced the outcome of this study. Feed intake and FCR were not considered in this study. Contrastingly, Lane & Kemp (1990) found that shearing feedlot lambs in hot weather increased
feed intake without increasing growth rate. It then seems reasonable to assume that feedlot lambs should not be shorn in winter as this will only lead to the animals consuming more feed without simultaneously improving growth. At higher ambient temperatures, such as will occur during summer, the answer is not so clear. Since shearing still causes stress, even though the thermal shock will not be as great as in winter, animals will not necessarily show improved growth after shearing. A suggestion would be to avoid shearing as long as the environmental temperature is below the upper critical temperature (UCT) for sheep. The UCT for sheep has been set as 34⁰C for hair sheep and between 30 and 32⁰C for wool sheep (do Prado Paim et al., 2013). If animals are only shorn when temperatures rise above these limits, excessive heat stress which could lead to depressed feed intake should be avoided while no unnecessary stress due to non-essential shearing will occur either.
Considering the available studies on the subject, two main conclusions can be made. Firstly, it appears that shearing lambs or two-tooth sheep, such as would ordinarily be found in feedlots, leads to increased feed intake by the animals (WodzickaTomaszewska, 1963; Lane & Kemp, 1990; Çam et al., 2007; Keady & Hanrahan, 2015). Secondly, in studies conducted on slaughter lambs, growth rates were not significantly improved by shearing the lambs prior to »
admittance to the feedlot even though feed intake increased (Lane & Kemp, 1990; Keady & Hanrahan, 2015). This means that the FCR of these lambs declined, making it less profitable to finish them off in a feedlot. It is possible that older sheep would display improved growth rates due to the increased feed intake associated with shearing (Çam et al., 2007), but this would not benefit feedlotters as mature animals have unfavourable growth rates when compared to lambs and will be less profitable to round off.
It therefore appears that, based on
current knowledge, there is little benefit to be gained in production terms from shearing feedlot lambs prior to rounding them off. Shearing per se may decrease profitability by increasing feed costs. Thus, the choice of if and when to shear feedlot lambs should be dependent on whether the wool-on hides or wool clip and shorn hides will provide the most income to the feedlotter. Due to fluctuations in feed costs and wool and hide prices, this will not be a static decision but will be dependent on the market circumstances at any given time. AP

Peyrot BM, Abolnik C, Anthony T, Roberts LC. Evolutionary dynamics of the clade 2.3.4.4B H5N8 high-pathogenicity avian influenza outbreaks in coastal seabirds and other species in southern Africa from 2017 to 2019. Transboundary and Emerging Diseases. 2022 Nov;69(6):3749-3760. doi: 10.1111/tbed.14744. Epub 2022 Nov 1. PMID: 36268570 https://onlinelibrary.wiley.com/doi/10.1111/tbed.14744
In December 2017, large numbers of sick and dead swift terns (geelbek sterretjies) were reported along the southwestern coastline of South Africa. Clinical signs included diarrhoea, corneal oedema, weakness and incoordination, circling and/or the inability to fly, and other neurological signs. Laboratory testing confirmed H5N8 high pathogenicity avian influenza (HPAI) infections. Previously the only other record of similar mass mortalities in coastal seabirds occurred in 1961. In that year another high pathogenicity avian influenza virus killed common terns (gewone sterretjies) along the Southern
African coastline from Lambert’s Bay to Gqeberha. It was time to investigate why this phenomenon re-occurred in 2017.
HPAI viruses are spread over long distances in asymptomatic infections of migratory birds. Between November 2016 and January 2017, outbreaks of H5N8 HPAI viruses from Europe, the Middle East or Central and South Asia were introduced to wild birds and poultry in Egypt, Tunisia and Nigeria, followed by Niger, Cameroon and Uganda before reaching the Democratic Republic of the Congo in April 2017. In May 2017, H5N8 broke out on a commercial poultry farm near
Greater crested tern (Thalasseus bergii), also called crested tern or swift tern.
Harare, Zimbabwe, and a month later the first poultry outbreaks were reported at Villiers and Standerton in South Africa. These were the first reported cases of these viruses south of the tropic of Capricorn, disseminated via movements of afro-tropical waterfowl.
The South African epidemic was characterised by two genetically distinct virus clusters. The first spanned regions of Gauteng, Mpumalanga, North West, KwaZulu-Natal and Free State provinces and comprised four different genotypes.
The second, larger southern cluster affected the Western (most severely affected) and Eastern Cape provinces with outbreaks from August to October 2017. More than 70% of the layer hen population was culled. Many wild birds found inland were also affected. All the outbreaks in this southern cluster were caused by only one genotype.
By early 2018, these viruses had caused mass die-offs of coastal seabirds along the southern coastline of South Africa. By May
2018, an estimated 7 415 birds of 15 species including African oystercatchers (swarttobie), African penguins (brilpikkewyne), Cape cormorants (trekduiker) crowned cormorants (kuifkopduiker), common terns, sandwich terns (grootsterretjies), swift terns and Hartlaub’s gulls (Hartlaubse meeue) probably succumbed to HPAI. Terns especially were affected, but high mortalities in endangered species like the African penguin caused international concern.
Coastal seabirds and a single jackal buzzard (rooiborsjakkalsvoël) that became moribund or died on beaches or at breeding colonies between the Olifants River estuary and Gqeberha were collected by members of the public, managing conservation authorities, rehabilitation centres and Veterinary Services. Samples from the birds were screened for the presence of HPAI virus. Viruses from 25 of these samples were included in this study.
RNA extracted from each virus was submitted to the Stellenbosch University for
genetic sequencing. Gene sequences and reference sequences from publicly available collections of sequences were compared. Phylogenetic analysis software was used to determine the timeline of how the viruses evolved.
The molecular data available from other researchers showed that West Africa was the source of the Southern African H5N8 outbreaks in 2017. Additionally, the Zimbabwean virus detected only a month before the South African event started, was closely related to, but not a direct source of, the South African viruses.
The coastal seabird viruses, a subgroup of the southern virus cluster, likely originated
from a single introduction to seabirds by terrestrial birds around October 2017. These viruses were only detected in coastal seabirds from the beginning of 2018, but they were the same genotype as the poultry viruses.
H5N8 HPAI virus-linked mortalities in Namibian penguins exactly a year after the SA event were unexpected. Analyses showed that the South African coastal seabird strains were the source of the Namibian outbreaks.
Dates derived from viral sequence analyses can be used to unravel the complex movements of wild birds.
Surveillance and reporting efforts for HPAI virus infections in wild birds should be expanded and intensified.
