How can commercial producers use breeding values without recording full pedigrees? This week, Mark chats with Carel Teseling, Chief Operating Officer at Angus Australia, to find out. 

Carel's career has taken him from South Africa's regional performance recording programs to 14 years of developing genetic tools for Angus Australia, a decade leading Australian Wagyu Association's genetics, and now back to Angus again, giving him unique insight into what actually works for producers across different systems and breeds.

Carel begins by sharing the story behind South Africa's groundbreaking work in livestock genetics during the 1990s, as well as his early days tackling genetic conditions in Angus, and his time at the Australian Wagyu Association.

After 10 years at the Australian Wagyu Association, Carel returned to Angus Australia in 2025 as Chief Operating Officer, where he's overseeing the parallel running of the Trans-Tasman (TACE) analysis and Angus's new internal analysis. 

He explains how the internal system has been in development for almost five years, includes new traits like immune competence and body condition, and uses different methodological approaches such as avoiding pre-adjustments on carcass data. 

Angus Australia is letting breeders compare both systems to see how they re-rank animals. Carel explains that while there will be some re-ranking, both point in the same direction and will still guide breeders toward genetic improvement.

Carel and Mark also cover

• Commercial breeding strategies
• The value of female data in maternal breeds
• How to identify and cull poor-performing dams
• Why commercial producers should pay attention to breeding values even without recording full pedigrees.

Ferg shares his thoughts on genetic gain in the sheep and beef industries. He has often said that we should be seeking to achieve a minimum of 2% genetic gain, but the top operators we deal with here at neXtgen Agri are consistently achieving 3-4%. Ferg explains how they’ve achieved that with the use of selection accuracy and the compounding effect of disciplined breeding decisions over time.

Ferg also talks about what that genetic gain actually means for each farm and what traits we should be looking at to optimise performance. Some traits benefit all farms, no matter the location (things like worms, dags and feet), and others that are more system-specific.

What if measuring worm resistance didn't require high parasite burdens and ALSO delivered double the heritability of egg counts?

Sarah Preston, Lecturer at Federation University and cofounder of Swabtec, explains the development of their saliva-based test designed to measure immune responses to gastrointestinal worms in sheep, allowing resistance to be assessed without relying on high worm egg counts.

She and Mark discuss why egg counts often fail to reflect adult worm burden, particularly in mixed infections and with species that regulate egg production, and how this affects breeding and management decisions in well-managed, low challenge systems.

They also discuss where they are with the development and validation of Swabtec. They are currently working to validate the test across breeds and environments and are planning to develop breeding values as the data builds. The test has been found to have a heritability of 0.4 compared to the WEC of 0.2 meaning flock improvements based on insights and data from Swabtec can occur twice as fast!

What limits ewe productivity in current sheep systems?

Our guest this week, Tara Dwyer is breeding manager at Headwaters Genetics and a farm manager within the Lone Star Farms group. Her work covers stud breeding, commercial supply chains, and large-scale sheep systems, and in amongst all of that, she found time to do a Kellogg report, "A New Fleece on Life: How the Sheep Farming Sector in Aotearoa Can Halt Terminal Decline to Secure a Sustainable and More Secure Future"

Starting with her "day job", Tara and Mark discuss the value of genetics within a value chain, and how Headwaters is focusing on eating quality traits alongside maternal performance, resilience, and low-input efficiency. Tara explains how and why Headwaters selects for intramuscular fat and fatty acid profiles while still prioritising reproduction, lamb survival, and health traits.

Mark and Tara then discuss her recent Kellogg report, which looks at why lambs weaned per ewe have barely shifted for decades, why carcass output improved while reproduction stalled, and why relying on ram breeders alone is not a reproductive strategy. Tara explains her findings on where current systems have plateaued, what existing technology already allows producers to measure, and why individual ewe performance will be one of the next major productivity levers.

On this week's episode, Tim Gole shares how sheep farmers can increase their profits by shifting from responding to problems to preventing them in the first place.

Tim runs ForFlocksSake, a vet-based sheep consultancy company. After a lightbulb moment during the drought, Tim became a self-confessed sheep fanatic.

With both Tim and Mark clearly in their element, they spend nearly an hour talking all things sheep. They discuss lifetime ewe programs, scanning strategies, the use of genetics to make production easier and more profitable, and the benefits and drawbacks of EID. They also cover reproductive efficiency, worm control lessons and lots of other sheep-related topics.

What do the genetics of tail length and the genetics of semen quality have in common? Not much, except that our guest, Marnie Hodge, Sheep Genetics Senior Development Officer, has researched them both.

Tail length is moderately to highly heritable, but in her research, Marnie found that measuring tail length in centimetres versus a scored system gives you far more accuracy and picks up significantly more genetic variation, which means faster rates of genetic gain if you're selecting for it.

But what's actually changing when tails get shorter? Are we dropping vertebrae or just shortening bones? And what about correlations with body structure? Marnie explains what we know, what we don't, and why we don't have a tail length breeding value quite yet. 

On the opposite end of the scale, as with all reproduction traits, semen quality is lowly heritable. Marnie's research, "Heritability and Genetic Parameters for Semen Traits in Australian Sheep", showed that most of the variation in AI success wasn't down to motility, but more down to the variation in ewe management on each farm. So what does that mean for the establishment of a potential future breeding value? Marnie explains on the podcast. 

Plus Marnie gives us some updates on what's coming from Sheep Genetics and the combined analysis.

How simple rotations and tight feed management lift whole farm performance.

Mark chats with Bevan Ravenhill, WA General Manager for Lawson Angus  WA, to talk about what really drives a productive grazing business. Bevan grew up on a dairy farm, and that early training in grass, rotation, and pressure has shaped the way he now runs sheep and beef across a mixed enterprise.

Bevan explains how a simple rotation, tight feed management and a focus on leaf stage have transformed grass utilisation on the farm. He talks through how their accelerated lambing system works in practice, why confinement feeding has become such a reliable tool, and how silage underpins the whole engine when feed becomes tight.

On the cattle side, Bevan shares the shift to moderate, efficient Angus cows and the lessons learnt from years of collecting real on-farm data. He digs into maternal efficiency, cow size, raw phenotypes and why consistency matters more than chasing extremes. They also cover spring calving, OptiWeigh and the role of pressure testing cattle rather than compensating for them.

Tune in to hear some great insights from someone who has spent a lifetime thinking about how to turn grass into kilograms.

Accounting may not be every farmer’s favourite topic, but it is one of the most powerful tools on the farm. This week’s Head Shepherd guest, David Egerton-Warburton, explains why.

Raised on a sixth-generation farm in Kojonup, Western Australia, David learned early that every on-farm decision ties back to sound business practice. His father, Kent, founded Agrimaster in 1981, bringing farm records into the computer age long before most households had a computer, and David and his wife have been joint CEOs since 2001.

David and Mark Ferguson discuss budgeting, risk control and decision making, and why financial literacy separates good farmers from great farming businesses. As David says, “The most successful growers aren’t that much better from a production point of view… what we really see is the difference in the ability to take risks because they can control them.” 

Listen to the episode to learn how to turn your farm numbers into a roadmap for success and take control of the risks that matter.

What makes farmers change? And what holds them back? Our guest this week, Dr Ruth Nettle, has spent 25 years studying just that. Ruth has spent her career looking into how people in agriculture learn, adapt, and lead.

Now leading the Rural Innovation Research Group at the University of Melbourne, Ruth has seen how agricultural extension, advisory networks, and rural communities have evolved through time. In this episode, she and Ferg chat about trust, workforce challenges, and what the future of extension looks like in a more commercial and tech-driven world.

They talk about what makes a great employer in agriculture, why a positive team culture matters more than pay, and how farms can attract and retain staff in a global skills shortage. Ruth also shares her thoughts on AI in agriculture, the importance of human-to-human learning, and what Australia could take from extension systems overseas.

If you work with farmers, lead a team, or care about the people side of farming, this episode offers great insight into agricultural workforce development, rural leadership, and the evolving role of extension in agriculture today.

Ever wished you could get breeding values on your commercial Merinos without having to record weights, dates or pedigrees?

This week, we’re launching neXtPredict, our brand new genomic tool that lets you go straight from DNA to breeding values with just a simple TSU sample.

Developed in partnership with Weatherbys Scientific, neXtPredict provides base genomic breeding values, parentage, poll/horn testing and a flock profile for Merino breeders. It’s powered by the MerinoSelect database and backed by MLA-funded research through AGBU and Sheep Genetics.

To announce the launch this week on the podcast, Ferg chats with Tamarah Luxton, Territory Manager at Weatherbys Scientific. Tamarah shares the story of Weatherbys’ journey from managing thoroughbred pedigrees in Ireland to providing cutting-edge genomic testing for livestock across Australia. 

neXtPredict has three service tiers, designed to suit everyone from large commercial breeders to data-driven operations wanting deeper insights.

• CORE gives you access to the neXtPredict Portal, where you can view gBVs, parentage, poll/horn, flock profiles and indexes, and filter or rank animals on standard industry indexes or generic neXtgen Agri indexes.
• PLUS includes everything in CORE, plus trait correlation analysis, the creation of custom indexes, and one-on-one support from the neXtgen Agri team.
• PRO adds long-term data storage, the ability to include non-genomic traits (like wool quality or dag scores), view multi-year data, and work directly with our consultants on testing strategies and optimisation.

If you are interested in using neXtPredict, get in touch with us here at neXtgen Agri:

Our guest this week is Vicky Alexandrou, co-founder of Woven Optics.

Over the past eight years, Vicky has helped design and build a handheld microscope that lets you measure wool fibre diameter right there in the yards or shed. 

Instead of waiting for lab results, you clip a small sample, take a few quick images along the staple, and within seconds, the device tells you the mean micron, standard deviation, coefficient of variation, and comfort factor.

You can scan the sheep’s ear tag so the data is linked instantly, meaning decisions on classing, culling or breeding can be made on the spot with the most up-to-date information.

Vicky and Ferg also chat about the importance of industry collaboration, the current commercialisation of Woven Optics, and the future potential of AI in agriculture.

Woven Optics is available now through your local Heiniger representative.

This week, we’re chatting about the differences between US and NZ sheep production systems with Dr. Whit Stewart, an Associate Professor and Extension Sheep Specialist in the Department of Animal Science at the University of Wyoming.

Whit has spent the last year on a sabbatical in New Zealand, learning and absorbing as much as he can about sheep farming here. Because of this, he has some great insights into the comparisons between systems as well as what we do well, and what we could do better at. 

He and Ferg chat about predator pressure, grazing public land, the structure of the US lamb supply chain, and what it's like farming in a country where golden eagles can take 40% of your lamb crop. Whit also chats about what he’s learnt here in NZ. Our use of tools like FarmIQ, a strong export focus, and top-notch forage management are our strong points, according to Whit. And he also shares what he thinks we could learn from the US in return.

It’s a great conversation with someone who is very passionate about building better sheep businesses, regardless of where he is on the globe!

This week we’re (belatedly) joined by Jack O’Connor, winner of the 2025 Zanda McDonald Award. Jack lives and works on the family’s fourth-generation mixed farming operation, Oxton Park, in southern NSW.

He and Ferg discuss his career so far and why, for Jack, business success comes down to the people and community he works alongside. And with 20 staff, 15 properties, and both livestock and cropping enterprises, that focus on people is essential!

They also chat about the importance of professional development, leadership, and mentorship. It’s a great listen for anyone thinking about the future of agriculture and how to bring their team along with them.
