In this week's episode, Sam talks with Ferg about finding agriculture through high school ag, building confidence without a family farming background, and the role mentors and community played in shaping her career. She and Mark discuss her work across the wool value chain, including auctioneering, technology and systems innovation within Elders, and the d...

2026/01/04

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...

Ferg's thoughts on genetic gain

Head Shepherd ·

2025/12/28

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 b...

2025/12/21

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...

How Do You Breed Short-Tailed Sheep? with Marnie Hodge

Head Shepherd ·

2025/11/23

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. B...

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 utilisat...

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...
