Impact of heat stress on the physiology, reproduction and production of goats

Even though goats are considered rustic animals, regarding the bioclimatic aspect, the association of high temperature, humidity and solar radiation may cause physiological, hematological, hormonal, reproductive and productive changes. Therefore, information explaining the impact of heat stress on the efficiency of these aspects on goats by analyzing the surrounding environment and how these animals behave themselves before the adversities imposed by the climate, will give a great contribution to goat breeding and the strengthening of this productive chain. Thus, to increase the productivity in tropical regions, the breed of animals presenting a major genetic potential of adaptability to adverse climatic conditions must be emphasized breeds that may be able to survive, reproduce and produce efficiently in a situation of heat stress.
