Episode 109 – Designing the dairy farm of the future
The Science for Farmers tent at the Wānaka A&P Show this year gave farmers a great chance to see and hear about a wide range of research as well as ways that’s being implemented on farms. Dairy Country Podcast host Anne Lee was there and talked to Danny Donaghy of Massey University, Pāmu’s Head of Sustainability Sam Bridgman, and LIC Senior Herd Improvement Specialist Simon Worth. Each shared the ways science and innovation are helping farmers respond to climate pressure, lift system resilience, and future-proof performance.
Host:
- Anne Lee, Senior Journalist, Dairy Country
Guests:
- Danny Donaghy, Professor of Dairy Production Systems & Deputy Head, School of Agriculture and Environment, Massey University
- Simon Worth, Senior Herd Improvement Specialist, LIC
- Sam Bridgman, Head of Sustainability, Pāmu
Danny Donaghy shares insights from the Whenua Haumanu research programme, challenging the idea that more pasture diversity is always better. Instead, he outlines a functional approach, selecting a small number of complementary species to improve yield, animal performance and environmental outcomes. His work shows that well-designed mixes can deliver measurable gains, often at lower cost, while helping farmers better manage drought, nitrogen loss and seasonal variability.
Simon Worth outlines LIC’s work on the slick gene, a naturally occurring trait that improves heat tolerance in cattle. He explains how the gene has been progressively bred into high-performing dairy animals, with the goal of delivering commercially viable bulls within the next few years. As temperatures rise, tools like this will become increasingly important, sitting alongside management and system changes to help farmers maintain productivity under heat stress.
Sam Bridgman explains how Pāmu is using detailed climate projections to help farmers understand future risks and adapt accordingly. By using tools to map changes in rainfall, heat and extreme events at a farm level, the work highlights practical, often simple adjustments that can improve resilience. From water management to system design, he emphasises that small, informed changes can strengthen both environmental and financial performance over time.
