羊体外寄生虫病防治

Prevention and Treatment of Ectoparasitic Diseases in Sheep

体外寄生虫病是放牧羊群中很容易发生的一种传染性疾病。羊体外寄生虫病的种类较多,威胁较大,并且具有很高的接触性和传染性,会严重影响羊的正常生长发育。一方面会损害皮毛,影响羊的增重;另一方面还会引发机体营养不良,甚至会引发大量死亡,给养殖场带来不可挽回的经济损失。羊体外寄生虫病虽然造成的死亡率较低,但是会严重降低羊群的饲料利用率,使养殖场的成本增加,不利于养殖效益的提高。对此,就需要加强流行病学调查,掌握本地区羊体外寄生虫病的种类,然后采取针对性的驱虫措施,提高防治效果。该文主要结合鄂温克旗的羊体表寄生虫病的发生现状,论述羊体外寄生虫病的诊断和防治工作,希望该研究对同行有所帮助。

Ectoparasitic disease is an infectious disease that is prone to occur in grazing sheep.There are many types of ectoparasitic diseases in sheep,which are more threatening,and have high contact and infectivity,which will seriously affect the normal growth and development of sheep.On the one hand,it will damage the fur and affect the weight gain of the sheep.On the other hand,it will lead to malnutrition of the body and even lead to a large number of deaths,which will bring irreversible economic losses to the farm.Although the mortality rate caused by sheep ectoparasitic disease is low,it will seriously reduce the feed utilization rate of the sheep,increase the cost of the farm,and is not conducive to the improvement of the breeding efficiency.In this regard,it is necessary to to strengthen epidemiological investigations,grasp the types of sheep ectoparasitic diseases in this area,and then take targeted deworming measures to improve the control effect.Based on the current situation of sheep ectoparasitic disease in Ewenki Banner,this paper puts forward its own views on the diagnosis and prevention of ectoparasitic disease.It is hoped that this research will be helpful to colleagues.
