热应激对鸡群的影响及防控措施

The Effect of Heat Stress on Chickens and its Prevention and Control Measures

热应激又被称为中暑症,是指鸡在高温条件下,由于体温调节和生理机能出现紊乱而引发的一种应激反应。鸡热应激发生后会伴随生产性能下降,甚至会造成鸡休克死亡,对家禽养殖产业造成的危害很严重,是夏秋高温季节易发生的一种热应激,特别是集约化规模化养殖场发病率更高。不管是肉鸡还是蛋鸡在养殖产业发展中,积极做好综合防控抗热应激,对提高鸡生产性能,增加养殖场经济效益都显得十分重要。该文主要论述热应激对鸡群产生的影响,提出具体的防控措施,并结合养殖场的发病实际探讨热应激造成的损失。

Heat stress,also known as heat stroke,refers to chickens in high temperature conditions,as a result of temperature regulation and physiological disorders caused by a stress response.The heat stress of chicken will be accompanied with the decrease of production performance,and even cause chicken shock death.It is a kind of heat stress that easily occurs in summer and autumn high temperature seasons,and has serious harm to poultry breeding industry,in particular,the incidence of intensive scale farms is higher.In the development of breeding industry,it is very important for both broiler and layer to prevent and control heat stress.This paper mainly discusses the effect of heat stress on chickens,puts forward specific prevention and control measures,and discusses the loss caused by heat stress combined with the occurrence of disease on farms.
