Dairynz Tech Series: Dairy Science In Action

When it comes to herd improvement, it’s easy to focus on high heritability traits like milk production and liveweight - where the gains are faster and more visible. But what about the traits that take time?In this episode of Talking Dairy, Jac McGowan and Dr Rhiannon Hancock, a scientist at NZ Animal Evaluation, talk about why low heritability traits deserve a place in your breeding strategy – especially if you’re playing the long game.Rhiannon explains how even small genetic gains in these areas can build over time, leading to big wins for herd productivity and long-term profitability. Find out:Why heritability mattersWhy slow progress is still real progressPractical tips for long-term herd improvementListen for the full story behind the science. This episode was inspired by the myth-busting story in the Feb-April edition of Inside Dairy – available at dairynz.co.nz/inside-dairy Resources for more information on this topic:Is focusing on low-heritability traits valuable when making breeding decisions? | Dair
