Global market access and brand integrity underpin Wagyu’s future growth.
Dear Members,
The past year has been one of reflection, growth, and resilience for both our industry and our association. As we navigate dynamic global markets, shifting consumer expectations, and the evolving challenges of agriculture, our Wagyu community continues to demonstrate strength, innovation, and unity.
Australia remains at the forefront of Wagyu genetics worldwide, and this year has only reinforced our reputation as global leaders. Through performance recording and the ongoing adoption of genomic technologies, we continue to refine the accuracy of Estimated Breeding Values (EBVs). These tools are vital for producers who are committed to making data-driven decisions that advance profitability, sustainability, and eating quality.
This year saw the release of the Genetic Diversity and Genomic Inbreeding tools, giving breeders clearer insights into the long-term health of their herds. For the first time, we have received valuable carcase data from the Progeny Test Program (PTP), strengthening the accuracy of genetic evaluations. The effect of this carcase data only reinforces the integrity and importance of the PTP. With only two sire intakes left before the completion of this program, I would encourage all members to start considering bulls for entry. In particular, members with genetically diverse bulls that carry the potential to drive significant progress in the breed. Importantly, these sires do not need to be elite across all traits, simply above breed average, to deliver meaningful contributions to the long-term genetic advancement of Wagyu.
These developments, combined with members’ commitment to recording and submitting data, ensure that Australia maintains its competitive edge in supplying superior Wagyu to domestic and international markets.
Global economic pressures, fluctuating cattle prices, and uncertainty in export markets have tested all beef producers. Yet, consumer demand for premium, differentiated beef has remained strong, particularly in key export markets such as Japan, Korea, the United States, the European Union, and the United Arab Emirates.
While F1 feeder prices have remained relatively subdued until recently, the expectations are that between now and Christmas feeder steers will be trading in the mid to high $5.00 range. Meanwhile, Purebred and Fullblood feeder prices have consistently maintained a strong 30-60% premium over F1s, with similar expectations ahead.
Within Australia, we are also seeing a growing appreciation for Wagyu’s eating quality, with butchers, restaurants, and retailers expanding their offerings of Wagyu-branded products. This reflects years of work by our members to not only produce outstanding beef but also to educate consumers on the value of the Wagyu eating experience.
Maintaining access to global markets and protecting the integrity of the Wagyu brand remain essential pillars of our long-term success.
Innovation has been a defining theme of the past year. The AWA proudly launched Wagyu Feeder Check 2.0, delivering an improved platform for members to benchmark their cattle against industry standards. We also reached a major milestone with over 50,000 carcase records now in our database, a tremendous achievement that reflects years of dedication from members submitting data.
“I am particularly encouraged by the participation of younger members and next-generation breeders. Their energy and fresh perspectives are essential for the continued evolution of our industry,”
In research, we are developing a new fatty acid test that will give further insights into beef quality, while also discovering new recessive traits to safeguard herd health. Importantly, the new Helical Database is now ready for use, providing a more powerful and flexible foundation for genetic data management.
What unites these initiatives is a clear focus on giving breeders more tools to make confident, forward-looking decisions. Each new capability, whether it be identifying recessives, refining carcase traits, or providing better benchmarking, creates opportunities for members to improve both herd performance and profitability. These advances not only strengthen our ability to produce worldleading beef but also ensure that our breeders are equipped with the tools to meet future challenges.
Since July, the AWA has been rolling out regional member engagement workshops in Tamworth, Toowoomba, Emerald and Ballarat. I had the privilege of attending the Ballarat workshop, which provided me with the opportunity to meet and engage with members. The enthusiasm, questions, and shared experiences at the event reminded me of the passion and dedication that run deep within our membership, and highlighted how important these opportunities are for ensuring that breeders of all sizes have access to the knowledge and tools needed to thrive.
These workshops are also helping to build stronger connections between members. Whether it is a large-scale seedstock breeder or a smaller operation entering Wagyu for the first time, every participant has a role in shaping the future of our industry. Creating spaces for this exchange of ideas and experiences helps ensure that we grow together, and that no member feels left behind in the rapid pace of change that defines the Wagyu sector.
I am particularly encouraged by the participation of younger members and next-generation breeders. Their energy and fresh perspectives are essential for the continued evolution of our industry, and it is my belief that they will carry the Wagyu breed to even greater heights in the decades to come. Together, we are not just building a stronger breed, we are shaping the future of Wagyu in Australia and beyond.’’

Empowering
Spring 2025
AWA staff planned and ran a series of in-person and online workshops over the July to September 2025 period to launch the new AWA Helical Database platform. Helical will be the AWA Breed Registry, data recording and display system for the Wagyu Industry.
Our workshops were highly attended and offered the opportunity for Members and Staff to meet and learn from each other through a range of example demonstrations and presentations. In addition to our November Technical Workshop and WagyuEdge Conference, the Regional Workshops provided a new platform through which AWA Members can engage with AWA staff and our services.
Thanks to our Workshop trade and meat sponsors who helped enable a vibrant and rewarding experience for attendees.
After many years of touring around the entire continent, from South to North and East to West, WagyuEdge’26 is coming home to Brisbane 15-17 April 2026. The conference will be held at the Brisbane Convention and Exhibition Centre in Southbank Brisbane and we expect the event to be our largest ever.
WagyuEdge’26 will be followed by a 4 day South East Queensland tour, commencing Saturday the 18th, with a tour of Australian Country Choice – Cannon Hill Wagyu processing and logistics facility along with exportation handling at Port of Brisbane. We will tour South to visit Ced Wise artificial breeding and stay in Wine Country, before heading through to see renown Fullblood Breeders Macquarie Wagyu and Arubial Wagyu near Dalby on the Darling Downs.
Our WagyuEdge’26 tour will finish with a visit to Kilcoy Global Meats to view Wagyu processing, followed by the Kilcoy Innovation Hub to learn about Wagyu cut value adding and the latest cooking and preparation innovation in Wagyu. We will finish the tour on the 22nd of April with dinner on the Sunshine Coast, before dropping off tour participants at Sunshine Coast of Brisbane Airport on the morning of the 23rd of April. This could be a once in a lifetime tour of some of the Australia’s and the Worlds largest Wagyu breeding and export processing programs.
The AWA 2025 Technical Workshop will be held from 10am 24th of November at the Hotel Grand Chancellor. We will have 4 hours of technical-based presentations followed by the AWA Annual General Meeting at 3:30pm. New AWA research and innovations will be presented along with the formal reporting of delivery against the AWA annual operational plan KPIs.
The AWA Board met 12 August 2025 in Melbourne Victoria, with the following items considered:
1. The AWA Board reviewed new applications from DNA testing companies to provide updated pricing and new DNA testing for AWA members. The Board approved new DNA testing partnership agreements that will see significant reduction in some DNA testing costs to AWA members.
2. The WagyuEdge’26 will be held in Brisbane Wednesday 15th to Friday 17th of April 2026. The Conference speaker program has been finalised. The Conference will be followed by a tour of Wagyu farms, feedlots and processors from Saturday 18th to Tuesday 21st of April, with coaches arriving back to Brisbane airport early Wednesday 22nd of April for participants seeking to return from Brisbane instead of the Sunshine Coast airport.
3. The AWA Board met with the leadership committee of the WagYouth Program, with presentations from WagYouth Committee Members reviewed. WagYouth is a Wagyu Fellowship funded group that undertakes regular activities for young professionals in Wagyu, for the purpose of providing educational, training and professional development support. The Board supported continuation of the Program and provided support for development of professional and agricultural corporate networks for the group.
4. The timing of events and location of the AWA 2025 Annual General Meeting were determined. The 2025 AGM will be held Monday 24th of November at the Hotel Grand Chancellor in Brisbane Queensland. The formal Notice of Annual General Meeting will be distributed to Members with the Financial Year 2025 Annual Report of the AWA later this year.
5. The Audited Financial Statements of the AWA were reviewed by the Board, along with performance for the full financial year to 30 June 2025. These items were approved for publication in the Financial Year 2025 Annual Report of the AWA.
6. Alongside the AWA 2025-2030 Strategic Plan, the AWA has developed a 5-year Business Plan to deliver on the 2030 AWA corporate strategy. The new AWA 2025-2030 Business Plan was approved by the meeting, noting that each year of the Business Plan forms the Annual Operational Plan of the AWA.
7. An analysis of carcase traits captured by the MIJ camera were reviewed, noting genetic and phenotypic relationships between the amount of marbling and different marbling fineness measures. The AWA is currently investigating optimal use of carcase camera parameters for obtaining genetic gain in marbling fineness that is independent from genetic gain in Digital Marble Score itself, noting the high genetic correlation between the two traits.
8. The meeting undertook a historic review of prior verification program designs and plans dating back to 2013, noting the existing AUSMEAT animal raising claim (published 2017) and the more than 600,000 DNA profiles held by the AWA. AWA members currently conduct genomic DNA testing and parentage on more than 100,000 animals per year. This is increasing with Wagyu Feeder Check testing which already conducts DNA verification in slaughter stock.
9. It is a requirement that the AWA Board approve all new members to the Association. The Board approve the 30 new applications for membership between 27 May 2025 to 12 August 2025.
On behalf of the AWA Board, it is my pleasure to provide this report to you.

When people think of beef nutrition, they usually think of protein or iron. Yet one of beef’s most under-appreciated strengths is zinc — a trace mineral that quietly supports immunity, fertility, growth, and repair.
Dr Anneline Padayachee
Zinc isn’t glamorous. It rarely makes headlines, but life can’t function without it. Across enzymes, hormones, and cell signalling, zinc is everywhere. Globally, more than 1 in 3 people are at risk of inadequate zinc intake [1,2]. For beef producers, that makes every animal more than just a source of protein — it’s part of the solution to a hidden nutrient gap.
Zinc underpins essential processes in the human body, with broad effects on health and performance:
• Immunity – Zinc regulates white blood cell activity, cytokine signalling, and antibody production. It is crucial for wound healing and pathogen defence. Deficiency impairs both innate and adaptive immunity, leading to increased infection risk [3,4]
• Fertility and reproduction – Zinc is required for sperm count, motility, and morphology, and also supports ovulation and implantation. During pregnancy, zinc supports placental function, fetal growth, and neurodevelopment [5,6]
• Growth and repair – Zinc drives DNA synthesis, protein synthesis, and cell division. It accelerates wound healing and tissue regeneration [7,8]
• Taste and appetite – Zinc-dependent enzymes maintain taste and smell. Deficiency causes hypogeusia (reduced taste) and anosmia (reduced smell), which can blunt appetite [9,10]
• Brain function – Zinc modulates neurotransmitters such as glutamate and GABA, supports synaptic plasticity, and contributes to memory and learning. Deficiency has been linked to mood disorders and cognitive decline [11,12]
Zinc is often described as a “type-2” nutrient — one whose requirements rise during periods of stress, growth, pregnancy, and infection. Reviews in recent years have reinforced that zinc needs are dynamic, not fixed: they climb during immune activation, wound repair, and rapid growth phases [13–15]
While zinc is found in many foods, bioavailability — the proportion absorbed and utilised — varies widely:
• Plant sources: Zinc in legumes, grains, nuts, and seeds is often bound by phytates, which inhibit absorption. A 2024 Nutrients review confirmed that high-phytate diets can significantly reduce zinc uptake, though food preparation methods such as soaking, sprouting, fermenting, or phytase supplementation can improve bioavailability [6]. A 2022 AJCN evidence review comparing vegetarian and non-vegetarian diets concluded that vegetarians often have lower zinc status due to both lower intakes and reduced absorption efficiency [7]
• Animal sources: Zinc from beef, lamb, pork, and dairy is much more bioavailable, partly because it is not bound by phytates, and partly because amino acids and peptides in meat enhance zinc absorption [8,19]
For this reason, dietary guidelines suggest vegetarians and vegans may need 30–50% higher zinc intakes to meet physiological needs [7,19]. This is not a criticism of plantexclusive diets, but a recognition of how different food matrices affect nutrient utilisation.
Beef consistently ranks as one of the richest, most practical sources of bioavailable zinc:
• A 100–150 g cooked serve typically provides 6–8 mg zinc, covering ~50–75% of daily adult requirements [20]
Because zinc from beef is highly bioavailable, smaller servings provide a more reliable nutritional contribution than equivalent zinc amounts from plant foods [6,19]
• National dietary surveys support this. In US NHANES analyses, adolescents who consumed beef had significantly higher zinc intakes than non-consumers [21]. Another Nutrition Research analysis found that adults who ate beef regularly had higher intakes of zinc, iron, and vitamin B12, with lower prevalence of inadequacies [22]
Beef isn’t just protein – it’s one of the world’s most effective and practical sources of zinc.
• A 2024 review in Animal confirmed that red meat (including beef) remains one of the most effective contributors to closing nutrient gaps globally [23]
Together, this makes beef a population-level safeguard against zinc deficiency and suboptimal intake.
Oysters are the classic zinc “headline food,” but the full picture matters:
Oysters (Pacific, Eastern, Rock oysters) » ~25–45 mg zinc per 100 g (6–8 medium oysters). That’s more than double daily requirements for most adults.
• Other shellfish (crab, lobster, mussels, prawns) » ~3–6 mg zinc per 100 g. Decent sources, but consumed less often than beef.
• Finfish (salmon, tuna, cod, barramundi) » typically 0.5–1.5 mg zinc per 100 g. Nutritious for other reasons, but not zinc standouts.
Beef (all breeds, cuts) » 4–6 mg zinc per 100 g cooked; a 150 g serve provides 6–8 mg. That’s ~50–75% of adult daily requirements, in a portion people actually eat regularly [21–23]
Takeaway: oysters are unbeatable for zinc density, and if you can afford to eat it regularly, by all means go for it. But beef is a more convenient source that can be used in a range of dishes, palatable for all age groups. However as beef is generally eaten more often, in practical serving sizes, it contributes more consistently to zinc intake at a population level.
Zinc’s importance doesn’t begin and end with the consumer. It is also a fundamental element within the farm system. In cattle, zinc contributes to immunity, fertility, skin and hoof health, and growth — factors producers are already acutely aware of. Likewise, soil zinc levels influence pasture and crop quality, which in turn shape the mineral profile of feed and forage.
Trace mineral management is a complex balancing act, influenced by soils, water, pastures, and feed composition. Farmers and their advisors navigate these challenges daily, drawing on both science and practical experience. What’s clear from the research is that zinc plays a role in supporting resilience — whether that’s through animal health, plant growth, or ultimately the nutritional profile of the beef produced [24–28].
For beef producers, the broader take-home message is this: zinc matters on both sides of the farm gate. It underpins resilient production systems, and at the same time ensures that the beef reaching consumers delivers one of the most bioavailable sources of an essential micronutrient.
People who choose plant-exclusive diets can obtain zinc from legumes, nuts, seeds, and fortified foods. Modern reviews recommend strategies such as soaking, sprouting, fermentation, and phytase supplementation to improve absorption [6,7]. Supplements may also be required in some contexts.
But for those who include animal foods, beef offers a straightforward and efficient way to meet zinc needs — no specialised food processing, no supplementation required. The real nutrition conversation is not “beef versus plants,” but how different foods contribute in complementary ways.
The real nutrition conversation is not “beef versus plants”
• Zinc is essential for immunity, fertility, repair, taste, and cognition.
• Beef is one of the richest and most bioavailable dietary sources of zinc.
• Seafood, especially oysters, is zinc-dense, but beef contributes more consistently to daily intakes due to frequency and portion size.
• On farm, zinc is part of the broader mineral balance that underpins resilience — in soils, animals, and ultimately the beef produced.
• Every beef animal raised contributes directly to closing zinc gaps in human diets.
Consumers may buy beef for taste and protein, but they benefit from far more than flavour. Each serve delivers a quiet but powerful nutrient that supports growth, healing, and resilience. For producers, that’s a story worth sharing: beef isn’t just protein — it’s one of the world’s most effective and practical sources of zinc.

The advancement of Wagyu genetics depends on breeding strategies that balance rapid genetic gain with longterm diversity and sustainability. For breeders aiming to strengthen traits such as marbling, fertility, and growth, MateSel provides a powerful tool to design data-driven, customised breeding programs.
MateSel is a software package developed by Professor Brian and Sandy Kinghorn from the University of New England in Armidale, NSW, to optimise selection and mating decisions in a breeding program. At its core, it uses Optimal Contributions Selection (OCS), a method that ensures maximum genetic progress while controlling inbreeding and maintaining long term herd diversity.
Already widely adopted across industries such as beef, sheep, dairy, pigs, aquaculture, forestry, and crops, MateSel is also a key driver of genetic progress in Wagyu breeding.
MateSel combines genetic evaluations (such as EBVs and genomic data) with breeder-specified constraints to generate a ranked set of matings. Its flexibility means it can accommodate both technical goals and on-farm logistics. Key capabilities include:
• Managing genetic defects by avoiding carrier-to-carrier matings.
• Managing trait distributions with Tactical Desired Gains, ensuring balanced progress across carcase, fertility, and growth traits.
• Integrating reproductive technologies such as Artificial Insemination (AI), In-Vitro Fertilisation (IVF), and Embryo Transfer (ET).
• Handling practical constraints like animal movement, semen/embryo availability, joining numbers, and patterns of mating.
• Using genomic information to increase accuracy in both selection and mating allocations.
By modelling thousands of possible combinations, MateSel provides a mating plan that reflects both the breeder’s longterm objectives and short-term operational needs.
The software creates a frontier, which reflects the emphases on $Index (e.g. BFI) vs Diversity (i.e. Coancestry)
Wagyu breeders face unique challenges, the breed’s global reputation depends on exceptional marbling and meat quality, while genetic diversity must be carefully preserved due to reliance on a relatively narrow gene pool. MateSel addresses these challenges by:
Maximising genetic gain in high-value traits such as marbling, carcase weight, and eating quality.
• Maintaining genetic diversity, reducing the risk of inbreeding depression in future generations.
• Allowing tactical breeding decisions, such as increasing fertility while maintaining carcase quality.
• Integrating seamlessly with genomic testing and BREEDPLAN EBVs, delivering evidence-based recommendations.
Restrictions can be imposed on different traits (EBVs) (e.g increase mean marble score of progeny).
Once that the run is completed a list of Matings with the Progeny $Index and Progeny Inbreeding is provided 02 03
As genomic testing expands and EBVs become more powerful, MateSel will continue to underpin the Wagyu industry’s progress. By combining Optimal Contributions Selection with practical on-farm constraints, the software ensures that breeding decisions today will secure both profitability and genetic sustainability for the future.

Marathon Wagyu’s Data-Driven Breeding Journey
On the fertile soils of what is known as the Central Highlands of Queensland near Emerald, the McCosker family has been raising food and fibre for nearly seven decades.
Their story begins in 1929, when the family purchased Codenwarra, by the mid 1990s, the baton had passed to the third generation. Michael and Susan McCosker purchased their own property, Marathon, in 1996, building a reputation for award-winning cotton while also expanding their cattle interests. Twenty years later, they added the neighbouring property, Lake Nash, transforming its old abattoir infrastructure into a backgrounding and artificial insemination hub for a growing Wagyu herd.
That pioneering spirit lives on, underpinned by irrigated cropping of cotton, wheat, chickpeas, and sorghum. Crops feed into the cattle program, and cattle fertilise the cropping, a circular model of stewardship and sustainability.
What began as a mixed enterprise of sheep, Herefords, and crops has grown into Marathon Wagyu, a business that now provides industry leading genetics to Wagyu producers across the globe. At its core is a philosophy that blends deep respect for heritage with a sharp eye on the future.
The McCoskers became pioneers of the Australian Wagyu industry in 1997 when John and Robin McCosker made the purchase of their first fullblood bulls to establish the Codenwarra Wagyu herd. Three years later, they expanded again with fullblood embryos and the Codenwarra Stud was established. It was an audacious move in an era when Wagyu markets were still emerging.
“John and Robin were ahead of their time,” explains Laine Thomson, who married into the family and now drives the Wagyu program. “They saw the potential of Wagyu long before it became mainstream, and they built a program known for big-framed maternal cows suited to northern conditions.”
In 2022, Michael and Susan, together with Michael’s sister Debra Postle, purchased Codenwarra and amalgamated its herd into their own. The Marathon and Codenwarra amalgamation brought together some of Australia’s leading genetics for maternal growth and carcase traits for balanced progeny.
“We had maternal records, but no idea how our carcases stacked up. Buying our own MIJ camera was about taking back control of that information.”
While heritage provides the foundation, data drives the future. Since 2018, Marathon Wagyu has been benchmarking carcase performance using an MIJ camera, a decision that transformed their understanding of the herd.
The camera has allowed Marathon Wagyu to capture precise carcase images and marbling scores on every steer processed, a game-changing shift after years of operating with little feedback.
“In the old days, most of our steers went to AACo, and once they were gone, we never saw them again,” recalls Laine. “We had maternal records, but no idea how our carcases stacked up. Buying our own MIJ camera was about taking back control of that information.”
With support from the Australian Wagyu Association and their “meat ninja” technical officer, Marathon Wagyu began collecting a complete dataset of carcase performance. Every kill was recorded, benchmarked, and compared across cohorts.
“It gave us a baseline, a reality check,” Laine says. “From there, we could start making real decisions. Which sires were delivering? Which cows should be retained? Were we trending in the right direction with marbling and carcass weight? Suddenly we weren’t guessing anymore.”
At the heart of Marathon Wagyu’s program is a commitment to protect the maternal growth traits that defined the early herd, while harnessing technology to refine carcase performance and consistency.
“Our vision is to keep building on what the McCosker herd was known for, growthy, maternal cows, while ensuring the next generation also delivers on carcase weight and marbling,” says Thomson.
With around 1,200 breeders and a fully integrated farming model, the enterprise now represents one of Australia’s most structured Wagyu breeding programs, providing elite genetics to producers worldwide.
The results have been encouraging. Over successive cohorts, average marbling has climbed from the high 7s to consistently above 8.3, all while maintaining the maternal base. “We could have chased a quick fix with a high-marbling sire, but we wanted sustainable progress,” Laine explains. “The MIJ data shows we’ve done that, every year, we’re nudging ahead.”
The camera has also guided reproductive decisions. Highperforming carcases are flagged for replication through AI and ET, while underperforming lines are gradually culled. “You can’t recreate the perfect animal, but you can tip the odds in your favour,” Laine says. “The MIJ gives us the evidence to do that.”
For Marathon Wagyu, the camera is not just a piece of equipment, it’s a cornerstone of transparency. “We advocate for data integrity and sharing results. Having our own MIJ means we know exactly what we’re producing, and we can stand behind it when we talk to other breeders, buyers, or customers.”
A key part of that improvement has been the adoption of MateSel, a genetic tool that optimises mating allocations.
“You start with the question: do you back the data? For us, yes absolutely,” Laine says. “MateSel gives us the ability to set clear objectives and stick to them: keep maternal growth, manage inbreeding below 12%, and still push forward with carcase improvements.”
The program allows Marathon Wagyu to run multiple mating “scenarios” each year. These include dedicated heifer runs with low-birthweight sires, AI and ET runs targeting genetic gain, and saleable female runs that identify the top-performing cows to retain in the herd. The software even highlights which bulls to retire and which younger sires deserve greater use, creating a long-term framework for herd renewal.
“The beauty of it is consistency,” Laine explains. “You’re not getting one calf that’s way above the rest and another that’s disappointing. Instead, you get a really even line right across the drop. Phenotypically they match, and genomically they’re
progressing each year. That’s the sign of a good herd.”
But Laine is quick to emphasise that technology is only part of the equation. “MateSel doesn’t know what a bull looks like. You can have the best EBVs in the world, but if the animal’s weak in structure, you just don’t use him. That’s where the breeder’s eye still matters.”
Marathon Wagyu’s pursuit of genetic progress extends beyond its own paddocks. The herd is both a sire nominator and contributor to the Australian Wagyu Association’s Progeny Test Program (PTP), a collaborative initiative designed to validate sires and accelerate breed-wide genetic improvement.
“We saw it as a chance to introduce outcross genetics and test them in our environment,” Laine says. “A bull might look great in one program, but until you see how he performs in the north, you don’t really know. The PTP gives us that insight, while also helping the industry as a whole.”
One standout example is their heavily used sire, P11. “He’s what we call our ‘super sire’, he combines growth, carcase weight and fine, highly marbled carcases,” Laine explains.
One standout example is their heavily used sire, P11. “He’s what we call our ‘super sire’, he combines growth, carcase weight and fine, highly marbled carcases,” Laine explains. “MateSel now wants to retire him because the next generation is testing even stronger. As much as it’s hard to see him go, that’s a good problem to have. It means the system is working.”
Participating in the PTP also strengthens accuracy of EBVs across the herd. By placing sires into different environments and collecting large volumes of carcase and performance data, accuracy lifts from 60–70% into the 90s. “That gives you real confidence,” Laine says. “If you’re going to build a herd around certain sires, you need to know exactly what they’re delivering. The PTP makes that possible.”
For Laine, being part of the PTP is about more than Marathon Wagyu. “We’ve always believed in transparency and sharing data. The Wagyu gene pool isn’t that big, if we all progress together, everyone benefits. The PTP is one way we can contribute back to the breed that’s given our family so much.”
Marathon Wagyu’s appetite for innovation goes beyond genetics. The family has invested in single-sire mating paddocks, water storage expansion, and agtech like FarmBot water monitoring and crop monitoring platform DataFarming.
“Managing 50 cows to one bull instead of 100 to three has been a game-changer,” Laine says. “FarmBot was another one of those investments where you think, why didn’t we do this sooner?”
Every investment is measured against a simple benchmark: will it deliver a return in both performance and sustainability?
Having built their herd from 350 to 1,200 breeders, Marathon Wagyu is now shifting gears. The next phase is less about herd expansion and more about targeted genetic refinement.
“We’ll always protect our maternal strength, but now we’re focusing more on traits like eye muscle area and carcass refinement,” Thomson explains. “I also think Wagyu will have a much bigger role in the broader beef industry, we’re already seeing F1 bulls used commercially in the north to lift fertility.”
Building on its cornerstone of family, Marathon Wagyu sees environmental stewardship as fundamental to a sustainable future. Best-practice management underpins both the cropping and cattle enterprises, while cutting-edge reproductive technologies, elite genetics, and full traceability ensure every animal is backed by robust data. Just as importantly, Marathon Wagyu champions transparency and integrity, recognising that shared information and accountability will drive the industry forward together.
What excites Thomson most, however, isn’t just the numbers or the genetics, it’s the people. “There’s nothing better than getting a call from someone who bought a bull from us, telling me how well his calves are doing. For us, it’s not just a transaction. We want those genetics to work for people, to move the whole industry forward.”
From the bold vision of the McCosker brothers to the data-driven strategies of today, Marathon Wagyu is a story of continuity and change, a herd shaped by tradition but sharpened by science.
“Wagyu has so much opportunity ahead,” Laine reflects. “If we keep making smart decisions about genetics, about diversity, about sustainability, the future is bright. For us, for the industry, and for the people who believe in what this breed can do.”
Genetic Progress
2025 marks 10 years of publication of Australian Wagyu Association carcase Estimated Breeding Values. The AWA introduced carcase EBVs in 2015, enabling the selection of Wagyu cattle for improved carcase trait performance using quantitative genetic tools.
The Australian Wagyu Association has grown significantly over the 2015 -2025 period as a result of a substantial increase in the number and scale of its members operations. This analysis provides feedback to members on how their contributions have impacted genetic progress for Wagyu cattle and to report some of the observed breeding trends.
The power of a genetic evaluation is influenced by the number of people who use it, the number of animals involved and the strength of the data that is analysed.
1: 10 year AWA Membership Trends
In Wagyu Update Volume 76 pp 33-46, we reported that the number of Full AWA Members had increased three-fold in the 10 years to 2020, with number of Full AWA Members totally 633. Fast forward to June 30 2025, and the number of AWA Full members has more than doubled again to 1,374, with an additional 170 Associate Members, bringing total membership of the AWA to 1,544.
Significant growth in membership and animal registration has occurred over the last 10 years since 2015, coinciding with the publication of AWA EBVs for carcase traits and the introduction of selection indexes that combine economic trait weightings with EBVs across all AWA reported traits.

Number of Calves
are
The number of animals registered with the AWA by year of birth is shows the significant acceleration in registrations starting in 2015 and continuing to 2023. More than 50,000 animals were registered in 2023. AWA members are still registering large numbers of 2024 born calves, with numbers already at 49,900. Calves registered for 2025 so far total 10,000, with the majority of the 2025 drop calves not born or DNA tested yet. In total, AWA now has over 450,000 animals registered. This is an increase of 340,000 since 2015.
The Wagyu genetic analysis is based on three components, a pedigree recording platform (the AWA Herdbook), phenotypic records (animal performance data for traits supplied by members) and genotype records (genomic data supplied by members). Using these sources of information, the AWA genetic evaluation uses statistical analysis to calculate the genetic merit of individuals using all available data to publish EBVs.
Wagyu EBVs (Estimated Breeding Values) use all available data within a genetic analysis model to calculate genetic merit for the production and carcase traits important for Wagyu breeders and supply chains. The analysis uses data from the 450,000 registered individuals, over 300,000 genomic records and an increasing volume of performance records (Figure 3).
Over the past five years there has been an increasing rate of phenotypic recording across the major growth and carcase performance traits. Records for Birthweight (BWT) now exceed 80,000 total records, 200 Day Weight (weaning weight) exceeds 110,000 records, whilst 600 day weight records now number 38,000. We note the difficulty in obtaining 600 day weight records from feedlot partners.
The AWA now has over 100 members who have submitted carcase data records, with Carcase Weight (CWT) and Marble Score (MS) records now at 50,000 and 49,000 respectively. Significant numbers of Eye Muscle Area (EMA) records began being recorded with the launch of the MIJ mobile camera in the 2020-2021 period. Since then, we have seen a rapid increase in EMA records to over 40,000.
Accuracy trends – the reliability of the analysis
As more members are submitting more phenotype records and undertaking large numbers of genomic testing on their herds, the impacts of these factors on the accuracy of genetic prediction for traits within the Wagyu genetic analysis is evident.
Shown in Figure 4 are the whole-of-database, average accuracies for the core growth and carcase traits since 2015. AWA switched to include genomic information for registered animals in 2017/2018. The large jump in wholeof-database accuracy for Wagyu EBVs can be seen in 2017.
As shown in Figure 4, the cumulative impact of new genomics information and performance data is spread across the whole of the AWA Herdbook and has a gradual positive influence on increasing accuracies. In the ten years since 2015, the whole-of-database average EBV accuracy for carcase traits has increased 17.5%.
Gains in accuracy for growth trait EBVs are lower, as a result of higher initial starting accuracy and lower amount of change being possible compared to carcase traits.
The overall trend for EBV accuracy for newly registered calves has been a substantial increase from an average of 47.5% for calves registered in 2015, to 65% for calves registered in 2025. The significant increase in accuracy for the EMA trait (Eye Muscle Area) results from a significant increase in MIJ carcase camera data for this trait. Notably, since the release of the MIJ mobile in 2020-2021, increased data submission has significantly increased accuracy for EMA.

We would like to thank our new and repeat buyers for your support in 2025. We wish you all of the success that we are experiencing with our poll genetics.
Every breeder has their own breeding objective for their herd, with AWA members managing production herds of females that are required to perform in a wide range of different environments from Northern Queensland to Tasmania and Western Australia. The following section demonstrates continued improvement (genetic gain) across a range of growth and carcase traits.
To understand genetic trends across the whole Wagyu herd, it is necessary to look at changes over a longer time frame, as genetic progress is gradual and cumulative. The following figures show trends over a 10-year period, looking at the average EBVs for traits of calves born within a year.
Early Life growth traits birth weight and weaning weights (200 day weight) show very slight increases across the last 10 year period (Figures 5 and 6). From 2015 to 2025, the average Birth Weight EBV has increased at 0.02kg per year. The average 200 Day weight EBV has also increased at a rate of 0.15kg per year over the 10 years to 2025. These findings suggest that changes to breeding decisions and genetic selection over the last 10 years have had little impact on early-life growth traits.
The trends for 600 Day Weight and Mature Cow Weight are more positive, with equivalent increases in both late-in-life weight traits. This suggests that breeders have selected more heavily for growth later in life and for a slight increase in mature cow size, most likely driven by a desire to increase feedlot entry weight.
Intellibond improves AI pregnancy rates
Intellibond improves embryo quality
Intellibond improves semen quality
Reproductive performance is a critical component in cattle profitability. IntelliBond trace minerals are scientifically proven to improve trace mineral status, which can lead to improved quality of bull semen, enhanced embryo quality and improvement in AI pregnancy rates, when compared to straight sulphates or combinations of sulphate and organic trace minerals.
Increases in genetic gain for carcase traits have been more dramatic than growth traits over the past 10 years, AWA members have made significant progress in genetic merit for core carcase traits. Consistent with increases in 600
Day weight and Mature Cow Weight, genetic gain in the Carcase Weight EBV has averaged +1.1kg per year, resulting in a 11kg increase in Carcase Weight EBV to +25kg.
In addition to the genetic gain for growth and carcase weight over the 10-year period, genetic gain for Marble Score has been substantial. The 10-year trend for Marble Score EBV is an increase of +0.13 MS units per year. This amounts to a +1.3 MS EBV increase over the past 10 years to +0.8.
There is a significant and positive genetic correlation between Marble Score and Eye Muscle Area in Wagyu. As the genetic potential for deposition of intramuscular fat within the Eye Muscle increases, the genetic potential for Eye Muscle Area also increases. The 10-year trend for increasing Eye Muscle Area EBV at +0.23 square centimeters per year, amounting to an increase of +2.3 centimeters over the last 10 years to +3.5.

10 yr trend = +1.3 MS units
Genetic gain improves breed averages and trait selection range
The genetic gain information provided earlier in this ariticle, shows breed progress for the “average” animal across successive breeding years. It demonstrates the year-on-year gain as a benchmark for the breed, reflecting the selection decisions made by AWA members.
Genetic selection can also impact the range available for genetic selection for each trait. Table 1 shows an abbreviated AWA EBV percentile table from 2017 (when single step EBVs were introduced) through to 2020 and 2023 (last available complete calving year with EBVs). Looking at the Middle 50% EBVs for all traits, we can see that these increase in line with the genetic gain changes reported in the earlier graphs, reflecting average genetic gain by the herd.
Looking at the top 1% EBVs for all traits, we can compare these across 2017, 2020 and 2023 born calves. Of note, is that all 2017 top 1% EBVs are lower than 2020 top 1% and 2023 top 1% EBVs. This means that in addition to making genetic gain through selection for favored traits, there is now a far larger range of genetic merit to select for compared to 2017.
If we refer to the “Animals registered with Australian Wagyu Association recorded by year of birth” figure 2 earlier in this article, we can also see that there were far fewer animals registered in 2017 (approximately 20,000), compared to the 54,600 registered in 2023.
This means that today’s breeders can manage breeding programs for more rapid increases in genetic merit for traits of importance for their herd, by accessing a larger number of animals with far higher genetic merit in their breeding programs.
Of interest in the EBV percentile table, is the reduction in trait variation for the Milk EBV. This has resulted primarily from an increase in the bottom 1% of animals for that trait, suggesting that breeders are avoiding very low milk EBV animals in their breeding decisions.
Making sense of genetic information
It is important to note that the EBVs reported by AWA are the cumulative result of the data submission of all members, reflecting the breeding directions of the membership as a whole.
The information presented here demonstrates that AWA members have made significant genetic progress for late-in-life growth traits and carcase traits. The trends toward increasing genetic merit of growth and carcase traits, demonstrate effective multi-trait selection. Very slight increases in Birthweight and 200 Day Weight may be considered positive, considering the reported slight increase in Mature Cow Weight and the need to produce calves that will thrive early on in life.
The continued increase in EBV accuracy for newly registered calves in the past five years is encouraging and reflects the contribution of performance data and genomic information. The submission of data from all members has resulted in substantial lift in accuracy for all growth and carcase traits recorded.
The higher accuracy for growth traits reported is largely a reflection of the increased volume of performance data for those traits. As more members become Wagyu data submitters and increased volumes of performance data is provided, accuracy and genetic merit will continue to increase across the herd, although the rate of gain in accuracy may plateau for highly recorded traits.
As EBV accuracy increases, it becomes easier for members to make genetic gain by more accurately identifying genetic merit within their herds. Matched with a significant increase in EBV range for most traits, we expect the rate of genetic gain to continue where members are placing continued selection pressure on those traits.

The Australian Wagyu Association’s Progeny Test Program (AWA-PTP) has now successfully completed four years of rigorous progeny testing. Since its inception, within the program we have joined up to 2,000 cows per year to cutting-edge Wagyu sires, marking several significant milestones along the way.
2025 marks a key achievement: it’s the first year that carcass data has been collected from progeny born within the program. To date, more than 2,200 calves have been born and registered, and over 125 sires have been admitted to the program, providing an unprecedented foundation for enhanced accuracy of their breeding values.
This progress is only possible thanks to the ongoing support and commitment of our contributor herds. The AWA is deeply grateful to the producers who have entrusted us with their valuable females and taken on the challenge of helping advance and benchmark Wagyu genetics, not just for their own herds, but for the betterment of the breed as a whole.
At the heart of the AWA Progeny Test Program are Australia’s contributor herds – producers working side by side with the Association to benchmark Wagyu genetics and build the most robust dataset the breed has ever seen.

Over the past four cohorts, 13 dedicated contributor herds have taken part in the program. These herds are the lifeblood of the AWA-PTP, raising and managing progeny under real-world conditions, which is essential for assessing the genetic merit of AI sires across diverse environments and management systems.
The result? A robust pipeline of performance-recorded animals that drive improvements in Wagyu Estimated Breeding Values (EBVs), helping producers make more informed and profitable decisions backed by real science.
With increasing interest in sire nominations for Cohort 5, the AWA is now calling for new contributor herds to join the Progeny Test Program.
To be eligible, applicants must be full members of the Australian Wagyu Association residing in Australia and willing to undertake a fixed-time AI program. Participation requires a herd size of at least 100 cows, ensuring a contemporary group of approximately 25 steers. Eligible herds must include at least 100 females that are either Fullblood, Purebred, high-content Wagyu, or Red Wagyu. The program is also able to accommodate larger herd sizes ie. up to 800 females

E very calf entered into the PTP increases the precision of Wagyu BREEDPLAN and enhances the accuracy of your herd’s EBV’s. The higher the accuracy, the more reliably you can select animals that will consistently pass on desirable traits, such as marble score, growth rate, feed efficiency, and fertility.
The PTP is designed to generate high-quality, standardised data across a wide range of environments, which leads to:
• Larger and more contemporary data sets: By testing common sires across multiple herds and conditions, we generate diverse phenotypic data that improves the reliability of comparisons.
• Increased linkages between herds: Common sires across contributor herds help strengthen genetic connections, which is vital for benchmarking performance across the overall herd.
• Genomic testing integration: All calves in the program are genomically tested, combining DNA data with real performance metrics to boost the predictive power of EBVs.
In short, the PTP allows breeders to increase the reliability of evidence-based decisions, reducing risk and increasing certainty, profitability, and long-term herd performance. If you’re aiming to lift the genetic precision in your own herd and contribute to a stronger, more data-driven Wagyu industry, this is your chance to be part of the foundation.
As a Contributor Herd, you’ll be among the first in Australia to access and apply next-generation, objective measurements to your females and their progeny, bringing science directly into your paddock.
Key innovations include:
• Net Feed Intake (NFI): Measures how efficiently an animal converts feed into weight gain, a crucial driver of profitability, particularly in feedlot systems.
• Fatty Acid Profiling: Provides detailed insight into intramuscular fat quality, helping identify animals with superior health traits and premium eating quality.
These advanced traits are difficult and expensive to measure on-farm, but through the PTP, your herd contributes to, and benefits from data that will redefine how Wagyu performance is measured and selected into the future.
When these traits are officially released, your herd will already have high-accuracy EBVs for them, as the progeny from your females have been measured as part of the program.

Helical ushers in a smarter, faster, and more connected future for Wagyu herd management
Helical is the world’s most advanced breed registry platform, purpose-built for the cloud and genomics era.
Designed to meet the demands of modern and future-focused livestock operations, Helical is powerful enough to manage complex data with ease, yet intuitive for everyday use in herd management and genetic decision-making.
It brings together all your essential information as a “one-stop-shop”, DNA orders, genotypes, test results, parent verification, weights, EBVs, and invoices into one seamless system.
Helical takes care of the hard data work in the background, so you can spend more time making smart breeding decisions that improve your herd and bottom line.
Helical is the world’s most advanced breed registry platform
Helical is built for adaptability and is meeting the evolving needs of members, staff, and the wider industry. It supports genetic improvement and herd development through precise data analysis and smarter decision-making tools. The system will help drive AWA growth by enabling innovation and efficiency, keeping the organisation at the cutting edge of livestock management through advanced technology. Designed with the future in mind, Helical can integrate new genetic indexes, emerging traits, and advanced selection tools, ensuring long-term relevance.
In contrast to the old database, which lacked flexibility and struggled to adapt to our changing needs, Helical is a major step forward. The previous database relied on multiple platforms, forcing members to log in to different systems to complete everyday tasks in-turn, slowing things down and making the process more frustrating. Now, Helical brings everything together in one place - a true one-stop shop, designed with simplicity and ease of use at its core. Whether you’re entering DNA records, registrations, transfers, matings, or performance data, the process is consistent and streamlined across the board.
All data in Helical is presented in clear, easy-to-read visual formats such as charts and graphs. These visuals help you interpret the data quickly, spot patterns or issues, and make confident decisions.
Helical has significantly streamlined key processes, leading to faster workflows and reduced turnaround times for both members and staff. Tasks that previously required multiple steps or extended waiting periods can now be completed more efficiently and with fewer delays.
As we move forward, Helical will incorporate API links and direct connections to commonly used industry databases (for example the NLIS Database), allowing data to flow seamlessly between platforms. This integration eliminates the need to manually transfer or re-enter information, saving time and reducing the risk of errors. By reducing double handling and minimising manual data entry, Helical improves accuracy and allows members to focus more on managing their herds rather than managing paperwork. One of the most noticeable improvements is the speed of parentage results. Under the old system, parentage analysis could take three to four days to process, including the time required for data preparation. In contrast, Helical can run parentage checks almost immediately after genotype data is uploaded to the database - delivering faster results and enabling quicker decision-making on-farm.
Implementing more robust Quality Assurance and Quality Control (QAQC) capabilities will lead to significantly cleaner and more reliable records. By increasing the ability to run automated QAQC checks throughout the workflow, potential issues and discrepancies can be identified and addressed much earlier in the process. This proactive approach helps maintain data integrity and supports more informed decision-making. Furthermore, reducing the reliance on manual intervention minimises the risk of human error, streamlines operations, and enhances overall efficiency. Automation not only ensures consistency and accuracy in
data handling but also frees up valuable time for staff to focus on higher-value tasks, ultimately improving productivity and confidence in the final outputs.
Helical isn’t just a new system - it’s a strategic leap forward. By streamlining processes, enhancing data accuracy, and supporting innovation, it equips the AWA community to work smarter, respond efficiently and be able to adapt to the changes within the industry.

A new tool in the management of calf scours.
You have invested in valuable genetics through careful selection and AI or ET programs and have live calves on the ground. There is nothing more frustrating than an outbreak of calf scours. Apart from the death of potentially valuable calves or growth and performance set-backs, they are a management nightmare in grazing situations. Sick calves can be difficult to catch and treat in the paddock and regular yarding of cows and calves can be disruptive to maternal behaviour and time consuming. Cattle yards and holding paddocks can become a potential source of other types of scours in calves already sick and debilitated. Very quickly, whole groups of calves can be affected.
Ultravac Scourshield is the latest and most practical vaccine to aid in the prevention and control of calf scours in Australia. Ultravac Scourshield is a pre-calving vaccine for cows and heifers, meaning calves receive protection via colostrum at the time they need it. The vaccine aids in the prevention of calf scours caused by bovine rotavirus (serotypes G6 and G10) and enterotoxigenic strains of E.coli, and controls scours caused by bovine coronavirus. Research has shown these pathogens to be among the most common causes of calf scours in Australian cattle, in particular Rotavirus.1,2
There is nothing more frustrating than an outbreak of calf scours
Ultravac Scourshield has a flexible vaccination interval of 3–9 weeks between the first and second doses; this allows you to fit vaccination around your current management practices. The second dose can be given 2–6 weeks prior to calving with the first shot being given 3–9 weeks prior to this. To ensure that calves receive the highest possible protection, plan your program around the expected calving date of your cows, move back 2-6 weeks for timing of the second dose, then work backwards from there for the first dose. Cows that have received two doses the previous year as heifers or at the commencement of the herd vaccination program only require an annual booster dose 2-6 weeks prior to calving.
Ultravac Scourshield is a low 2ml dose in a minimally reactive formulation injected into the muscle or under the skin for reduced tissue reactions.
Ultravac Scourshield works by stimulating specific antibodies within cows. These antibodies are then transferred into calves via colostrum when they are born. When calves suckle colostrum within the first 12–24 hours after birth, the antibodies are absorbed, which helps protect them against the devastating effects of scours. The first few weeks of life is a critical period for calves and calf scours and the effects can be long lasting. Where calves experience an episode of scouring in the first 2 months of life and recover, it has been shown this can have a negative impact on the animal’s body weight a year later.3
It’s essential to correctly time the vaccination of cows. It is also essential to ensure that calves are sucking vigorously straight after birth and receive an adequate quantity of colostrum. Inadequate intake of colostrum can also lead to other common disease problems in calves like pneumonia and joint ill. Heifers or cows that have trouble calving are at particular risk. Talk to your vet about strategies to ensure adequate colostrum intake in weak or mismothered calves and about ways to monitor your calves to ensure they are receiving adequate good quality colostrum from their dams.

Fixed-Time Artificial Insemination (FTAI) is increasingly being adopted in Wagyu herds to achieve more compact calving, improve fertility outcomes and accelerate genetic progress. Research in Australian beef herds has shown that FTAI can shorten calving windows, lift pregnancy rates compared with natural joining alone and enable wider use of high-index sires across joining groups (Meat & Livestock Australia, 2020; Burns et al., 2011).
“From the 1950s, when Artificial insemination meant semen was frozen in pellets and used in just a few stud herds, we’ve grown to technologies that now underpin the entire beef industry. Australia has risen from those experimental beginnings to stand at the forefront of bovine genetic advancement worldwide.”
— Dr Ced Wise
For Wagyu producers, these benefits go beyond fertility alone. A more even calf drop improves the accuracy of Wagyu BREEDPLAN recording, supports earlier weaning weights and allows progeny to be evaluated more consistently. By using semen from elite sires across an entire group, FTAI can also reduce generation intervals and provide a clearer pathway to faster genetic gain (Diskin & Kenny, 2014).
Reproductive soundness is the foundation of any successful program. For heifers, veterinary examinations to confirm both maturity and the absence of any problems such as pregnancy or the presence of freemartins before the program commences ensures the best possible outcome. For the best pregnancy rates wet cows should not be included until calves are at least six weeks old. When assessing empty cows, it is important to ask why they are empty - for instance, if they were held over due to drought — as these cows typically record lower conception rates.
Vaccination protocols also underpin success. Ensuring cattle are covered with 7in1® and have up-to-date boosters before the program starts is essential, while additional vaccines such as BVDV, Vibrio and IBR may be considered depending on herd history. Protecting reproductive health before a program directly supports conception rates and future herd performance.
“Reproductive soundness sets the ceiling for what your FTAI program can achieve.”
Wagyu fertility is highly responsive to energy balance and mineral status. If females are below a body condition score of 2.5 out of 5, including Novormon in the program can help promote follicle growth and improve conception. Equally important is ensuring cattle are on a rising plane of nutrition from just before program starts through to at least six weeks post-AI.
Trace minerals also matter. In herds where deficiencies in selenium, copper or zinc are known, supplementation can make a measurable difference. For seedstock herds, these nutritional foundations not only improve conception but also influence the performance data later entered into Wagyu BREEDPLAN.
Choosing the right synchronisation protocol is critical. Programs need to be matched to the class of cattle and their body condition. In EU-accredited herds, oestradiols such as Gonadiol, Bomerol and Cipiosyn are not permitted for use. Conception rates may be 5–10 per cent lower as a result. Understanding and planning for these differences ensures outcomes are realistic.
Equally important are the people managing the program. Holding a toolbox meeting before commencement, reviewing protocols and ensuring everyone understands dose rates and timing helps avoid errors. Product safety also matters — for example, prostaglandins must not be handled by pregnant women or asthmatics — and applicators should be cleaned and disinfected between uses.
Low-stress handling is another cornerstone. Calm cattle not only cycle better but also contribute to more accurate data collection — a key factor for seedstock breeders who depend on reliable performance recording.
For Wagyu breeders, semen represents some of the most valuable genetics in the beef industry. Protecting that investment requires discipline at every step. Requesting batch-level semen analysis is best practice, particularly where rare or high-demand sires are used.
Semen should remain in static storage tanks, with only the required straws moved to transport tanks for use at the yards. Thawing must be precise — 35°C for at least 30 seconds — and insemination is carried out within 10 minutes. Buckets should be kept below the frost line and handled efficiently to avoid exposing straws to damaging temperature changes. Ensure the semen goblets are accurately identified and their location in the tank is also clearly identified - do not lif5 every bucket searching for the correct semen.
Before insemination, the cow’s vulva should be cleaned and the procedure carried out by an experienced technician. Protecting semen quality is not just about conception today — it is about ensuring the genetics represented in Wagyu BREEDPLAN are given every chance to perform.

Pregnancy scanning from 30 days post-AI or after shifting the mop-up bulls from the paddock provides clarity on conception rates, while ageing pregnancies allows mobs to be split ahead of calving, supporting safer calving and smoother rejoining.
Early and accurate pregnancy diagnosis underpins Wagyu BREEDPLAN reporting. More even calf drops improve contemporary group structure and as the Australian Wagyu Association notes, larger groups (6–10 head) significantly enhance EBV accuracy for traits such as 200-day weight, fertility and marbling. In this way, FTAI is not just a reproductive tool but a driver of better data and stronger genetic evaluation.
FTAI has never been about shortcuts — it is about preparation, precision and learning from experience.
Decades of research and practice in the beef industry point to the same conclusion — FTAI success comes from attention to detail and continual refinement.
There are many variables that contribute to a successful AI Program and identifying the factors that contribute both to the success or otherwise is somewhat hard to do given the number of variables and environmental influences beyond our control.
The summary below highlights Figure 1– Pregnancy Tested In Calf (PTIC) results achieved through FTAI across 6 properties. All properties used the same synchronisation protocol and same semen sires.
Key findings across the 6 properties:
• Average females AI’d: 162
• Average PTIC result: 54.7%
• Highest PTIC result: 69%
• Lowest PTIC result: 27%
“At Wise Repro, our objective is to ensure all properties can achieve the highest PTIC rate, therefore increasing profitability through more efficient breeding. We continue to collect data and analyse the results to reduce the variables.”
