Internal parasite control in New Zealand sheep farming is one of the single biggest challenges to efficient sheep production. In this episode, Al & Juddy sit down with veterinarian and farm advisor Trevor Cook to explore the history, challenges, and future of parasite management. They discuss the growing resistance to anthelmintic drugs, why traditional drenching strategies are no longer enough, and the need for a more holistic, farm system based approach. From pasture management to alternative forages, this conversation covers how farmers can reduce parasite burdens without over-relying on chemical treatments.
