鸡场热应激临床症状及防控

Clinical Symptoms and Control of Heat Stress in Chicken Farm

热应激是环境中的温度过高,引发鸡生理机能和调节系统出现紊乱的一系列症状。盛夏季节如果没有做好鸡饲料的科学搭配工作,能量饲料供给不足,蛋白质饲料添加过量,鸡生长发育速度较快,机体产生大量热能,皮下脂肪较多,易引热应激。热应激会降低采食量和抵抗力,易感染多种传染性疾病,甚至会引发群体死亡,带来的经济损失不可估量。夏季鸡场热应激,发生原因十分复杂。需要养殖户充分认识该病造成的危害性,提高重视程度,进入夏秋季节后,注重做好鸡舍温度湿度的调控工作,确保鸡能安全度过夏天。该文主要论述养殖场的发病经过、鸡场热应激综合症的诊断和防治过程。

Heat stress is a series of symptoms caused by the excessive temperature in the environment,which leads to the disturbance of physiological function and regulating system in chickens.If the scientific collocation of chicken feed is not done well in midsummer,the energy feed supply is insufficient,the protein feed is added excessively,the chicken grows fast,the organism produces a lot of heat energy,the subcutaneous fat is more,easy to induce heat stress.Heat stress reduces food intake and resistance,predisposes people to a wide range of infections,and can even lead to mass infectious disease,with immeasurable economic costs.The causes of heat stress in chicken farm in summer are very complicated.It is necessary for farmers to fully understand the harmfulness of the disease and to pay more attention to it.After entering the summer and autumn season,they should pay attention to the temperature and humidity control of the henhouse so as to ensure the safety of the chickens in summer.This paper mainly discusses the course of disease occurrence,diagnosis and prevention of heat stress syndrome in chicken farm.
