Abstract Indicine cattle, also referred to as zebu (Bos taurus indicus), play a central role in pastoral communities across a wide range of agro-ecosystems, from extremely hot semiarid regions to hot humid tropical regions. However, their adaptive genetic changes following their dispersal into East Asia from the Indian subcontinent have remained poorly documented.

Introduction Heat stress is one of the main concerns of the poultry industry, especially in warm areas, as it causes major economic losses in both layer and broiler farms. Intensive genetic selection in breeding programs has led to an increased growth rate and metabolism. However, the development of the chicken thermoregulatory system cannot be matched with the growth rate, making it difficult for industrial chickens to regulate their body heat as temperatures fluctuate (Havenstein et al., 2003).
