Abstract:

In recent years,the number of goat farming in Southern China has increased year by year,and the intensive degree is becoming higher and higher.However,the climatic characteristics of high temperature and high humidity in Southern China can easily lead to the heat stress response of goats,which leads to the reduction of production performance and hinders the rapid development of sheep industry in the South.At present,in the field of heat stress regulation,most domestic and foreign scholars focus on the research and development of nutritional additives for relieving heat stress.And there is a lot of research on the effects of heat stress on the rumen microbial and rumen structure damage of goat,but it is still worthy of further research.In the future,it is necessary to carry out systematic research on the evaluating indicators of whether the goat is in the form of thermal stress and the degree of heat stress,and carry out the research on the molecular response mechanism,cytokines and HSPs under the heat stress condition of goat.The authors focuses on the effects of heat stress on goat behavior and physiological indexes,the molecular regulation mechanism of goat during heat stress period,and the prevention and control measures of heat stress.The aim of this paper is to provide references for carrying out large-scale breeding of goat in Southern China and the summer heat stress regulation.

Key words: goat; heat stress; regulation mechanism; prevention and control measures
