Show Notes

In this week's podcast, we're talking a whole lot about testicles! Our guest, Professor David Lindsay, shares his passion for the biology of reproduction and optimising ram usage on-farm. 

David was at the University of Western Australia in the 1960s, a time when the region was experiencing significant land clearance. The Department of Agriculture recognised the need for a lecturer in the reproductive physiology of sheep to address the increasing demand for sheep. He took up the role and sheep numbers quickly rose from a deficit to a surplus in just two years.

David shares some best-practice ram management principles, such as focusing on the last 54 days before mating to optimise sperm production. He also explains optimum ram-to-ewe ratios, taking into consideration the age of both animals, their condition and seasonal effects. 

Reflecting on his career,  David emphasises the importance of effective scientific writing, a skill he developed over the years and now teaches to a wide range of industries, astrophysics included! "Nobody knows you're there if you don't write," says David. "However, one of the things I found as I went on publishing this sort of material, was how difficult it was to write," he says. Professor Lindsay believes that writing should aim to inform, not to impress, a principle he has passed on to aspiring scientists.

David has a huge wealth of knowledge and we only just scraped the surface.
