  • Turning grass into money - this time with cattle, with Joe Kerin
    Jun 14 2026

    What does a cow actually cost to run?

    At Kerin Ag, every kilogram of utilisable feed has a value attached to it. That allows Joe Kerin and the team to measure whether an animal is genuinely paying its way.

    In this episode, Joe joins Mark to discuss how putting a dollar value on each kilogram of grass they grow led them to choose Wagyu over Angus. As any Kerin would, Joe has done the numbers and compared Wagyu cows with larger recipient cows, based on the weaning weight of their calves relative to the kg of dry matter consumed by the cows. And, as predicted, the moderate-sized cow is far more efficient than the larger Angus X recipients.

    Joe also discusses the role of genomics in Wagyu breeding. As they are a breed with a very narrow gene pool and are bred for carcass-related attributes, genomics is incredibly important, and Joe utilises it to its fullest.

    Tune in to learn how to turn grass into money- this time with cattle.

  • Forty years at Wairere Romneys with Simon Buckley
    Jun 7 2026

    Few people have had a front-row seat to the genetic improvement of New Zealand sheep quite like our guest this week, Simon Buckley.

    After growing up in Whangārei and starting his farming career at Castlepoint Station, Simon joined Wairere Romneys and has never left. Four decades later, he has helped one of New Zealand's most influential sheep breeding programmes through the transition from visual selection and paper records to EID, genomics and data-driven breeding.

    In this episode, Simon chats with Mark to discuss the history of Wairere and the long-term thinking required to make meaningful genetic progress. They also discuss maternal instinct, breeding sheep for commercial conditions, the challenge of balancing innovation with market demand, and the lessons he's learnt from those who have travelled through the "University of Wairere".

    Grab a coffee and sit back and enjoy this one - it's a goodie!

  • Refugia, resistance testing, and the future of worm management with Chloe Frank
    May 31 2026

    Most sheep producers assume their drenches are working. Chloe Frank's job is finding out whether they actually are.

    After discovering how few producers in her region were monitoring worm burdens, Chloe launched Central Stock Health while still at university. She now travels from farm to farm delivering on-site worm egg counts and helping producers make better management decisions.

    In this episode, Chloe joins Mark to discuss the challenge of drench resistance in Australia and why better information is often the missing piece in sheep management. She explains why the delays associated with traditional testing methods mean many producers still are not testing, and how her on-farm service is helping farmers access real-time results.

    Chloe and Mark also discuss how she built a business from the ground up while still at university. Chloe also highlights the multiple opportunities available to young people in agriculture. However, in recording this podcast, it is obvious that her passion for making a positive, practical difference to the Ag industry has played a significant role in her success so far.
