Reducing waste and increasing agri-food sustainability with OPTIGEN®

Ongoing protein supply and pricing pressures coupled with scaling environmental demands, makes for a complex situation for all U.K. dairy and beef enterprises both now and looking to the future.

A vital component in overcoming this challenge, is supplying modern productive ruminants with optimal levels of ammonia for the rumen to function effectively. Excess ammonia leads to excreted nitrogen waste, whilst a deficit impacts fibre digestion.

Optigen® provides a slow-release consistent source of non-protein nitrogen (NPN) to the rumen bacteria over time, leading to an increase in microbial protein, an improvement in fibre digestion and a reduction in nitrogen excretion.

A recent meta-analysis on Optigen evaluated the results of 17 dairy studies carried out in 6 countries, and 17 beef studies carried out in 9 countries. The research found Optigen to be a viable substitute or supplementation for plant protein sources in ruminant rations.

The proven benefits of Optigen in dairy cows

• Reduces soybean meal use by 21%

• Improves feed efficiency by 3%

• Improves nitrogen use efficiency by 4%

• Increases production profitability of a 1,000-dairy herd by £13,035

• Lowers the carbon footprint of a 1,000-dairy herd by 647 tonnes of CO2e

The proven benefits of Optigen in beef cows

• Improves both feed efficiency and liveweight gain by 8%

• Reduces time to slaughter by 9 days

• Increases production profitability of a 1,000-beef herd by £14,146

• Lowers the carbon footprint of a 1,000-beef herd by 111 tonnes of CO2e

Azelis offers a range of plant-based protein products.

Highly concentrated and digestible potato, pea, wheat and corn proteins can be used as alternatives to or partly replace traditional proteins.

TUBERMINE® GP potato protein provides protein enrichment and is known for its richness in essential amino acids available in higher amounts than in traditional proteins. The outstanding digestibility is particularly well suited to the young, newly-weaned animal’s high protein requirements and is well recognised as an excellent source of protein for piglet feed.

LYSAMINE® GPS concentrated protein extracted from peas, is a valued nutritional ingredient in many applications. Its excellent digestibility along with its naturally low antitrypsin activity makes it a protein of choice in the nutrition of young animals, particularly piglets.

VITEN® Vital wheat gluten natural protein extracted from wheat, is a water-insoluble complex protein.

Recognized especially for its high glutamic acid content, the plantbased protein shows exceptional digestibility and can be used in the formulation of high-performance feeds by limiting the risk of non-digested protein in the large intestine.

It is a useful alternative protein source which is appreciated in milk substitutes and piglet feed for its excellent digestibility, colour and palatability.

GLUTALYS ® corn gluten meal is a highly digestible protein concentrate rich in sulphur amino acids (methionine cystine). A polyvalent protein source, it offers advantages in formulas for ruminants because of the low natural degradability of the protein fraction in the rumen and its high post ruminal digestibility.

BENEO Sustainable alternative ingredients in animal feed

With increased scrutiny on ingredient sustainability in animal feed, BENEO, one of the leading manufacturers of functional ingredients, has recently launched a range of faba bean hulls and starch rich flour that

Page 56 SePtember/OctOber 2023 Feed Compounder Feed Ingredients …

can be used as a vegetal protein or fibre source for animal feed.

Faba beans are a very promising crop, due to their ability to fix nitrogen from the air for themselves and subsequent crops, reducing both fertilizer input and greenhouse gas emissions (GHG) at farm level. Additionally, being a local source of vegetal protein, their use avoids imports of raw materials from outside Europe. BENEO’s faba ingredients are produced in Germany and it strives to source the beans at Farm Sustainability Assessment (FSA) Gold level from German farmers. Also, the production process has been chosen for its low energy consumption in comparison to alternative processes, overall contributing to BENEO’s carbon neutrality and sustainability targets. With a faba bean range that includes hulls, starch-rich flour and protein concentrate, BENEO offers feed compounders a non-GMO and sustainable source of fibre, energy and protein. These quality ingredients allow for the development of feed formulas with sustainable alternative sources.



RumiPro® Urea – a high quality slow-release urea for optimising protein supply in ruminants. R elease the full power of your cows by the use of RumiPro ® urea and produce more milk solids. RumiPro ® Urea has a high-quality non-palm-based fat coating for a constant release of nitrogen in the rumen. It offers additional options to optimise the protein supply of the rumen microbes helping to maintain an efficient rumen fermentation. RumiPro® Urea increases microbial protein yield and supports cellulolytic bacteria to improve fiber digestibility. The high nutrient density is crucial to create a well-balanced diet for high producing dairy cows and opens additional possibilities in case of suboptimal forage quality.

TechnoYeast® - Kluyveromyces fragilis for function and flavour

TechnoYeast ® is a hydrolyzed yeast based on the strain Kluyveromyces fragilis, a specific strain of yeast suitable for feeding all species. TechnoYeast® is produced by a gentle process in which all nutrients are released and made more available for high digestibility, meeting the needs of young animals. TechnoYeast® contains both components of the yeast cell wall – mannan oligosaccharides (MOS) and β -glucans – along with the constituents of the yeast extract: highly digestible proteins, essential and functional amino acids such as the umami-tasting glutamic acid, nucleic acids as a source of nucleotides, and minerals. The combination of increased palatability, with the addition of nucleic acids, gives both improvements in feed intake and improved gut functionality, resulting in animals which consume more and can make better use of nutrients. TechnoYeast® has applications for all animal species where increased feed intake is beneficial.

Borregaard is a leader in bypass protein technology, supplying markets worldwide for more than 30 years. Our products SoyPass, RaPass and Amipro feature high levels of undegradable, yet highly digestible protein that are perfect for today’s ration balancing programs.

Soybean meal and rapeseed meal are known to be high value protein sources for animal feeds. During digestion, however, some of the vegetable protein is broken down in the rumen of the cow, far too early in the digestive system for the high yielding cow to fully use it.

Bypass products overcome this problem by protecting the protein while in the rumen, but allowing it to be fully digested within the small intestine. Consequently, better utilization of the essential amino acids occurs resulting in improved milk production.

SoyPass, RaPass and Amipro are manufactured and sold by our approved licensees. All of our bypass proteins are produced according to our strict quality requirements, and are among the most consistent bypass proteins on the market.

Kemin’s amino acid program for better raw material allocation in ruminant formulation

is an opportunity for ruminants to produce more efficiently through increased protein utilisation and reduced nitrogen excretion, having one of the biggest impacts on farm profitability and sustainability. The cow has specific requirements for individual amino acids and both Methionine and Lysine, which are the first essential limiting amino acids. An inadequate supply affects animal health and productivity. Amino acid nutrition also provides flexibility in formulation when selecting or substituting different feed materials due to either price or availability.

Table 1 describes the ingredients and nutrient profile for three diets, Control diet, Scenario 1, without soybean meal and Scenario 2, with soybean meal, but with 65% lesser amount than the Control diet. All meet the protein requirements for 35kg of milk at 4% and 3.5% milk fat and protein respectively. But Scenarios 1 and 2 also meet amino acid requirements by using KESSENT® Me and LysiGEM™ (rumen-protected Methionine and Lysine, Kemin Industries), saving 84g of metabolisable protein.

The formulation with Kemin´s rumen-protected amino acids improved the nitrogen efficiency, by 2.1% from 28.8% (Control), to 30.9% (Scenarios 1 and 2), with a better allocation of available raw materials at less cost.

Rising feed prices, their high volatility and low availability are the most limiting challenges presently facing dairy farm viability. However, there

Proteins and fats can come from many sources, but perhaps one of the most novel is that found in insects.

The advantages to using insects (specifically black soldier fly larvae) are numerous. In addition to being a source of high-quality protein and fatty acids, insects are powerful ‘up-cyclers’, meaning that they can feed off large quantities of local agricultural by-products, can be bred in vertical farms with low environmental impact and are part of most animals’ natural diet. In addition, they are a sustainable and ‘circular’ ingredient with local, European origin.

Cargill is already using insect protein within its Aqua Nutrition business as it can be produced using a fraction of the land, water, and resources required with lower emissions than traditional production, thus helping fish producers meet their sustainability goals. The company is finding new ways to reuse by-products and develop fish nutrition that promotes and enhances the health of farmed fish. Beyond being a high-quality feed offering, Innovafeed’s insect meal can save up to 16,000 tons of CO2e (carbon dioxide equivalents) for every 10,000 tons of insect protein, depending on the composition of the feed.

While Cargill’s initial collaboration with Innovafeed has focused

on Aqua Nutrition, the expanded partnership includes more species, starting with the use of oil derived from insects in swine and poultry feed. Using insect oil in piglet diets represents a reduction in the carbon footprint of the oil component of the diet by up to 81% compared to vegetable oil sources. After three years of running trials and exploring the practical solutions to be able to use insect oil in piglet feed, Cargill is now at the stage where piglet feed with insect oil is being produced and sold to certain markets outside of the UK.

In addition to application in piglets, Cargill is pioneering trials to compare insect oil versus plant oils in broiler diets, and to date has found similar performance with no detrimental effects. The insect oil from black soldier fly larvae is relatively high in lauric acid. It is further exploring the expected benefits of lauric acid in insect oil on broiler gut health and welfare.

When the trials on broiler feed conclude, Cargill will look to work with customers to bring more products from insect-fed livestock to retailers’ shelves and to consumers who are increasingly recognising the use and benefit of insects in meat production, including as an alternative and sustainable source of protein and oil.



As part of its long-term and continued strategy to reduce the carbon value of feed in pig diets, the latest ABN trials looking into soya alternatives are returning encouraging early performance results, while significantly reducing environmental footprints.

With soyabean meal being one of the main contributors to the carbon value of feed, including land use change, ABN has been working on an ongoing programme of trials looking at alternatives, in part driven by retailer requests.

“There has been some work across the industry considering the use of pulses as an alternative to soya in monogastric diets, but these latest trials are looking at the next step, considering whether a pre-processed pulse and rape blend can either replace or significantly reduce the use of soya in pig rations,” explains Dr Steve Jagger, ABN’s senior pig nutritionist.

Two separate trials are currently underway, across over 1,000 weaning pigs and a total of 4,000 finishing pigs. At the mid-way point, early signs are highly encouraging.

Finishing pig trial

The trials with finishing pigs, from 40kg to slaughter, have been looking at four levels of replacement, from full inclusion of soya all the way down to complete removal. It is being undertaken through three phased diets, at the growing, intermediate finishing and final finishing stages.

“During the three growth stages different pre-process pulse rape blends were utilised in the full replacement of soya,” explains Dr Jagger.

The first stage of the trial, with 2,000 finishing pigs, has now been completed and has shown good performance levels, with equal performance to the soya-based diet. The next stage is due to complete before the end of the year, and the results will be combined and analysed.

Weaning pig trial

The weaning pig trials, with pigs from 10-40kg, have looked at another pre-processed pulse rape blend.

“While soya cannot be completely removed from the weaning pig diet, we have been able to significantly reduce it and achieve a good performance,” adds Dr Jagger.

“While growth rate was maintained, intake was increased but the carbon reduction was significant,” he says.

Reduction in carbon value of feed

From the trials to date, there has been an approximate 40% reduction in the carbon value of feed, including land-use change, when comparing the full soya inclusion against the highest pre-processed pulse rape blend diet. These calculations are based on GFLI figures.

“These are significant reductions, and extremely encouraging. We are very enthused to see these trials through to their culmination, and will then combine and analyse the total results,” says Dr Jagger.

“Our driver is to try and develop products to help the industry reduce its carbon values. While at the preliminary stages, these latest trials look like a significant step forward in this space,” he concludes.
