How much do you hate daggy sheep? Well, what started as a frustration with daggy sheep ended up reshaping this week's guest’s entire farming system.

This week, Allan Richardson explains how his determination to eliminate daggy sheep ultimately led to three decades of organic farming and the adoption of regenerative principles.

He began by wanting to select for low dag score, but a local vet encouraged him to focus inst...

Ever wondered about farming New Zealand sheep in the UK, or considered farming UK shedding genetics in Australia? In this episode of Head Shepherd, Ferg speaks with Ian McDougall, a veterinarian whose career - and sheep - have taken him across Australia, New Zealand and the UK.

Ian grew up on marginal country on South Australia’s Eyre Peninsula before moving into veterinary work and artificial breeding. Over the past four decades, h...

Growing up in Western Sydney with no connection to agriculture, Samantha Wan’s path into the wool industry was anything but typical.

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...

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, ...

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 ...

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 eg...

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 mea...
