Effects of heat stress on dairy cows.

This episode discuss a research paper that examines the effects of heat stress on the production performance of dairy cows. The authors specifically focus on how high temperatures and humidity impact milk production in Sahiwal cows in Pakistan. They analyze the relationship between heat stress, hormone levels (cortisol, progesterone, and luteinizing hormone), and milk yield. The study concludes that heat stress significantly reduces milk production by disrupting the hormonal balance in cows.
