Abstract
Buffalo production is economically relevant in tropical regions, where high temperatures and humidity predispose animals to heat stress. Under these conditions, heat stress is a major limiting factor for reproductive efficiency, impairing follicular development, estrous expression, and conception rates. Physiological and hormonal alterations associated with thermal stress reduce dominant follicle diameter, increase the incidence of silent ovulations, and suppress sexual behavior. This review summarizes the main reproductive effects of heat stress in buffaloes and highlights their productive implications. The adoption of appropriate environmental management and housing strategies is essential to mitigate thermal stress and sustain reproductive performance under climate change scenarios.
Keywords: buffalo production, heat stress, fertility, animal reproduction
