In this episode, we sit down with farm vet Tonia Simms to talk about how dairy farmers can work with nature and science to reduce antibiotic use, improve fertility, and create more efficient, sustainable systems. From improving genetic gain to shortening calving periods, and reducing carbon output through healthier herds, Tonia brings practical insight and grounded advice for farmers navigating the ever-changing demands of modern agriculture. We explore how preventative approaches – like better housing, bacterial bedding products like Cobiotex, and smarter reproductive management – can support healthier cows and healthier margins. Plus, we’ll hear what a day in the life of a farm vet looks like, how Tonia balances family life, and what keeps her inspired in her work.
