  • Genomic data management and the future of breeding values with Dan Garrick
    May 17 2026

    What does it take to build the data systems that sit behind your genetic evaluations?

    This week on the podcast, Ferg catches up with Dan Garrick from Helical. Dan grew up on a sheep, beef and venison farm in the Manawatu before moving to the US at 13, where he went on to complete a PhD in aerospace engineering at Iowa State University. He's the son of Professor Dorian Garrick, one of New Zealand's most respected animal breeding geneticists, and his grandfather was one of the world's leading experts on sharks, making Dan a third-generation PhD.

    Dan explains how the same maths used to model fluid dynamics around rockets is used to generate breeding values, and how he ended up joining the family business in 2017 to help roll out some of the first production single step evaluations in the US for American Hereford and IGS. That work quickly revealed a major bottleneck in managing the genomic data flowing in from DNA testing labs. That's where Helical was born.

    Ferg and Dan talk through how Helical now serves breed societies, genetics companies, universities and labs across beef, dairy, sheep, horses, dogs, aquaculture and forestry. They also look ahead at where things are going. From decision support tools and AI in commercial herds, to the potential for wearable devices like virtual fencing collars to generate entirely new breeding values nobody has thought of yet - both Dan and Ferg agree the future is bright for Agriculture.

  • Lessons learned from LambEx with Jane Kellock
    May 10 2026

    Jane Kellock joins Mark to talk through the production and business decisions that have shaped their Merino operation in South Australia’s Mid North. From running a non-mulesed flock for more than 20 years to building a breeding programme focused on lamb survival, Jane explains how genetics, condition scoring and lessons learned from attending previous LambEx conferences have helped their business through some brutal seasons.

    Jane also discusses the importance of making strategic decisions before drought hits, why mixed farming regions risk losing livestock knowledge, and what producers can expect from LambEx26.

  • How to run a farm business your bank trusts, with Matt Hood
    May 3 2026

    Matt Hood on farm succession, agribusiness banking, and building better farm businesses.

    Based in Marlborough, Matt has worked across sheep and beef, dairy, and viticulture businesses in both New Zealand and Australia, with a focus on succession planning, equity partnerships, and helping farm businesses make better decisions around people, capital, and structure.

    Matt explains where he sees the gap between being good on the tools and being good in business. As businesses grow, priorities shift to managing people, finances, and decision-making, and that is often where performance stalls, especially during succession.

    On that note, succession is a major passion for Matt. Not just how to transfer assets, but how to run the process properly by having early conversations and making sure there is actually a business worth passing on, alongside a strong emphasis on purpose, both for the next generation coming in and for those stepping back.

    Matt also explains what the good, strong businesses he's come across consistently do well. It usually comes down to a good understanding of numbers, avoiding surprises, and keeping emotion out of decision-making.

    Matt and Mark also discuss what "good" looks like from a banking perspective and how to build up a good relationship with your bank so that you can work together for the success of everyone.

    This is an hour every farmer needs to listen to.
