Efeito do estresse térmico sobre os parâmetros reprodutivo dos caprinos.

Abstract

Climate is one of the environmental factors that has the strongest impact on animal welfare and, consequently, on production and productivity. Although they are well adapted to semi-arid climates, goats also experience heat stress. Room temperature and relative humidity can cause thermal discomfort in the animal, which can lead to stress. Heat is constantly produced by the body as a result of metabolism, so heat loss is necessary to prevent the body's temperature from rising to unacceptable levels. The stress caused by high environmental temperatures also affects the reproductive capacity of male goats, the ambient temperature is the factor that most impacts spermatogenesis in males, and when it is too high, it is harmful throughout the stages of sperm formation. Control measures to avoid these impacts must be taken, strategies can be adopted to reduce the severity of stress during hot weather, shade structures are provided for the animals with the main objective of protecting them from direct sunlight and reflected light diffuse. The objective of this work was to carry out a bibliographical review, to collect data about the effects of thermal stress on the reproductive parameters of goats.
