羊体外寄生虫病危害及防治措施

Harm and Control Measures of Ectoparasitic Diseases in Sheep

寄生虫疾病是羊养殖领域的3大疾病之一,该类疾病具有独特的特征,传播速度较为缓慢,具有较强的传染性,常呈地方性流行,不同地区的寄生虫疾病存在很大的差异性。根据寄生虫寄生位置的不同,将其划分为体表寄生虫病和体内寄生虫病。体外寄生虫主要会对羊的体表、毛发构成严重的威胁,并引发一系列的临床症状,危及羊的健康生长,并且很多体表寄生虫自身繁殖生长过程中除与羊争夺营养物质外,还会产生大量毒素,使患病羊出现不同程度的体表中毒现象,造成患病羊生长发育迟缓,皮毛失去光泽,生长发育不良。由于体外寄生虫造成的死亡率相对较低,常被养殖户忽视。该文探讨了养体外寄生虫病的危害,并提出防治措施。

Parasitic diseases are one of the three major diseases in sheep breeding.These diseases have unique characteristics,slow transmission speed,strong infectivity,and are often endemic.Parasitic diseases in different regions are very different.According to the different positions of parasites,they are divided into surface parasitic diseases and internal parasitic diseases.Ectoparasites mainly pose a serious threat to the body surface and hair of sheep,and cause a series of clinical symptoms,endangering the healthy growth of sheep.In addition to competing with sheep for nutrients,many ectoparasites also produce a large number of toxins,resulting in varying degrees of body surface poisoning in sick sheep,It causes the growth retardation of sick sheep,loss of luster of fur and poor growth and development.The mortality caused by ectoparasites is relatively low,which is often ignored by farmers.This paper discusses the harm of raising ectoparasitic diseases,and puts forward the corresponding prevention and control measures.
