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...

Selecting for Worm Resistance in Low-Challenge Systems with Swabtec

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

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...
