Thermal stress is caused by the impacts of climate change and constant heat on animals, negatively influencing the performance of production animals. The recurring resources to its various mechanisms that are essential for its survival in extreme situations, on the other hand, the production performance of dairy cows is reduced. These physiological changes are observed by means of several parameters, among them, the blood blood parameter One of the best because of its sensitivity to temperature variations, the blood system is important, in addition to evaluating the health status of the animals it is an indicator of situations of thermal stress. Bovine cattle are designed when the stress of exposed proteins is different), increasing milk concentration, reducing plasma by trying body fluids and temperature within the limit. , through breathing and sweating, being obese also the increase in erythrocytes which consequently increases circulation and tissue oxygenation, raising the level of hemoglobin in the. The leukogram has been identified as a blood component that exhibits influences under stress, and may present cases of leukocytosis by neutrophilia, lymphopenia and in some cases the presence of eosinopenia, the latter two of which have limited significance in the leukogram of heat stress.
