Professor David Lindsay has spent a lifetime at the forefront of Australian agricultural science but this conversation goes far beyond the lab.

In this episode, Bill sits down with David to explore a career that shaped modern understanding of animal reproduction, fertility, nutrition, and farmer–scientist collaboration. From early breakthroughs in sheep fertility to the role of lupins, hormones, and gut biology, David reflects on the discoveries that genuinely changed farming systems across Western Australia.

Along the way, David shares candid stories from the paddock, the lecture theatre, and the research world that reveal how knowledge is built and how it can be lost.

This episode is essential listening for scientists, agronomists, farmers, students, and anyone interested in how ideas shape industries, policy, and public trust.
