摘要 [目的] 了解羊寄生虫的感染情况，并为羊场寄生虫病的防控提供科学依据。[方法]在A、B山羊场采集新鲜粪便，采用饱和食盐水漂浮法、水洗沉淀法、卢戈氏碘液染色—镜检法进行山羊粪便寄生虫虫卵的检查和鉴定，并通过虫卵计数测定感染强度。[结果] A羊场检测到球虫、线虫、绦虫，B场检测到球虫、线虫、绦虫和吸虫，其中B羊场的感染强度要大于A羊场。[结论]2个羊场都感染了寄生虫，其中B场需要进行全群投药。

Abstract [Objective] The research aimed to study the infection situations of parasite in goats and provide scientific basis for the prevention and control of verminosis in goat farm. [Method] Fresh dung was collected from A and B goat farms. The parasite eggs in the dung of goats were examined and identified by using saturated brine floating method， washing sediment method and Lugols iodine stainingmicroscopic method. And the infection intensity was determined by egg counting method. [Result] Coccidia， nematodes and tapeworms were detected in A farm， and coccidia， nematodes， tapeworms and trematodes were detected in B farm. The infection intensity of parasite in B farm was greater than that in A farm. [Conclusion] The infection of parasite was found in two goat farms. All the goats in B farm should be administrated with drugs.

羊寄生虫病在羊场内广泛存在，且种类很多，综合国内文献可知，山羊感染的肠道寄生虫主要有胃肠道线虫、球虫、莫尼茨绦虫、肝片吸虫、前后盘吸虫、矛形双腔吸虫、隐孢子虫、贾第虫、阿米巴原虫等^[1-3]。

由于寄生虫长期消耗羊的营养、对羊造成损伤从而降低饲料报酬，影响羊的增重速度，还会造成羊免疫力下降，容易继发感染其他疾病，甚至造成死亡^[4]。由于国内不同地区气候、植被、地形、饲养方式和药物使用等不同，感染山羊的消化道虫种有一定差异，在某一地区温度和湿度均较适宜的夏秋季节感染性幼虫数量最多，此时为羊胃肠道寄生虫的主要感染阶段^[5]。基于此，2014年4月，笔者选取安徽省某地区存栏在500头左右的山羊场2个，进行粪便寄生虫虫卵的检查和鉴定，了解羊寄生虫感染的情况，并为羊场寄生虫病防控提供科学依据。……
