会理黑山羊消化道寄生虫的感染情况调查

Infection Status of Gastrointestinal Parasites in Huili Black Goat

为黑山羊消化道寄生虫病的防控提供参考,采用离心沉淀法和饱和盐水漂浮法对56份会理黑山羊新鲜粪便中的寄生虫卵或卵囊种类进行检查,以鉴定其消化道寄生虫病的感染情况。结果表明:1)会理黑山羊消化道的寄生虫有4类(线虫、吸虫、绦虫和球虫)13种。其中,线虫10种,分别为马歇尔线虫、细颈线虫、夏伯特线虫、奥斯特线虫、毛圆线虫、食道口线虫、捻转血矛线虫、羊仰口线虫、乳突类圆线虫和其他园线虫;吸虫1种,为肝片形吸虫;绦虫1种,为莫尼茨绦虫;球虫1种。2)寄生虫的总感染率为92.86%。其中,线虫的感染率最高,达89.29%;球虫次之,为83.93%;吸虫最低,仅3.58%。球虫和马歇尔线虫为优势寄生虫。自然放牧下黑山羊消化道寄生虫的感染率较普遍,应采取相应措施进行综合防控。

The infection status of gastrointestinal parasites was identified by inspecting parasite egg or oocyst samples collected by centrifugal sedimentation method and brine floating method from fresh faeces of 56 households of raising Huili black goats to provide a reference for controlling gastrointestinal parasitic disease of Huili black goat.The results showed that：1）There are 13 species of four types including Marshallagia.spp.,Nematodirus.spp.,Chabertia.spp.,Ostertagia.spp.,Trichostrongylus.spp., Oesophagostomum. spp., Hemonchus contortus, Bunostomum trigonocephalum, Strongyloides papillosus,Moniezia.spp.,Fasciola hepatica,Eimeria spp. and other Strongylus spp;2 ） Total infection rate of gastrointestinal parasitic disease is up to 92.86% and the infection rate of nematodes, Eimeria spp,Moniezia.spp and Fasciolahepatica is 89.29%,83.93%,14.29% and 3.58% separately. The dominant parasitic species are Eimeria spp and Marshallagia.spp. The corresponding measures should be used to control gastrointestinal parasitic diseases because the infection rate of gastrointestinal parasitic diseases is high in Huili black goats under the natural grazing condition.
