Effect of Heat Stress on Bovine Reproduction

Heat stress is a major challenge in cattle production systems, particularly in regions with high temperatures and humidity. Its effects extend beyond animal comfort, directly influencing reproductive efficiency in both dairy and beef cattle. This webinar examines how elevated environmental temperatures affect reproductive physiology, estrus expression, conception rates, embryo survival, and overall fertility. The session also discusses the impact of heat stress on male and female reproductive performance, along with practical approaches for mitigation through housing, nutrition, herd management, and environmental modifications. Understanding these effects is essential for maintaining reproductive success, improving herd productivity, and reducing economic losses associated with heat stress.
