ABSTRACT
Heat stress is failure of heat dissipation of body when too much heat is produced. Summer season is the most detrimental for production in animals especially reared in tropical and sub tropical area. Exotic dairy cows are more prone to environmental stress as they have more heat of metabolism. Moreover, they are high producer and high producer animals are more susceptible to heat stress. Heat Stress has harmful impact on production, reproduction, metabolism and immune status of animal. Semen quality of exotic cattle is also affect by heat stress. Similarly, fertility decreases during highly warm months due to heat stress. In managemental perspective, cooling systems (Fans and mist) along with shades and grazing at night are involved in environmental modification. Due to heat stress, intake of dry matter decreases but requirement of energy increases along with the bypass protein. So there is need of nutrition based management of animals in proper way.
