摘要
蛋鸡夏季热应激是指在高温高湿条件下,其生理机能和体温调节机能出现运行紊乱的一种非正常状态。该病常发生于每年7—9月。蛋鸡热应激症状出现后会进一步影响机体正常代谢,导致鸡群采食量下降,进而危害机体的身体健康,影响蛋鸡正常生产。同时,蛋鸡夏季热应激还会造成机体抵抗能力下降,易激发感染多种传染性疾病,威胁鸡群的正常生长,甚至会造成大批量的鸡死亡。该文主要论述夏季蛋鸡养殖中热应激的发病特点、临床表现、病理变化和防范措施,进一步降低夏季蛋鸡热应激的发病率。
The heat stress of laying hens in summer is a kind of abnormal state in which the physiological function and thermoregulation function appear disorder under the condition of high temperature and high humidity.The disease usually occurs in seven to nine months per year.Heat stress symptoms of layers will further affect the normal metabolism of the body,lead to the decrease of feed intake,and then endanger the health of the body,affect the normal production of layers.At the same time,heat stress in laying hens in summer may cause the body's resistance to heat stress,which may easily lead to infection of various infectious disease,threaten the normal growth of chickens,and even cause the death of a large number of chickens.This paper mainly discusses the disease characteristics,clinical manifestations,pathological changes and preventive measures of heat stress in laying hens in summer to further reduce the incidence of heat stress in laying hens.
