Abstract:
The dairy sector, more than any other livestock system in tropical regions, is facing enormous challenges in maintaining productivity in the face of rapidly changing climatic conditions. There is currently a lack of understanding about the combined effects of climate, season, and farm location on trait responses in various cattle breeds. Heat stress (HS) is caused by an imbalance between metabolic heat production within the animal body and its dissipation to the environment in hot and humid climates. Heat stress has a number of serious and economically damaging effects on cattle. The most significant effects of heat stress in dairy cows are increased body temperature and decreased milk production.
