Climate change is increasing the risk of heat stress in livestock, with implications for animal welfare and reproductive performance in the Thoroughbred breeding industry. This project examined the impact of ambient temperature and humidity on stallion fertility, including effects on sperm production and DNA integrity during the breeding season. The findings highlight variability in stallion responses to heat stress and underscore the importance of tailored management practices, such as adjusted stabling and paddock access, to protect fertility and welfare. This research supports evidence based decision making to enhance productivity and long term sustainability within the Thoroughbred Horses Program.
