Effect of climatic factors on milk production of triple crossbred (Holstein Friesian 25 % X Jersey 25 % Kankrej 50 %) cows

The effect of heat stress is caused by high ambient temperature and high relative humidity (Kadzere et al., 2002). At high temperature several physiological changes occur in dairy cow and they attempt to facilitate heat dissipation, if they failure of homeostasis of high temperature may lead to reduce productivity or even death (Kamal et al., 2018).
