摘　　要：为解决放牧犊牛因遭受寄生虫侵袭而发育受阻、死亡增多等问题,通过粪便检查虫卵幼虫、血片镜检查血液原虫、体表检查收集外寄生虫和蠕虫学剖检查内寄生虫等多种方法,收集虫体标本5万余条,分类鉴定出31种,其中吸虫3种,绦虫及绦虫蚴2种,线虫13种,蜘蛛昆虫9种,原虫4种。隶属于6纲12目21科27属。针对牛弓首蛔虫等危害严重的寄生虫病侵袭与传播特点,制定实施程序性驱虫及综合防控措施。经走访追踪调查,驱虫牛比同龄未驱虫牛的出栏期提早2个月以上,销售价格提高20%以上。In order to solve the problems of blocked development and increased death of grazing calves due to parasite invasion, more than 50 000 specimens were collected by fecal examination of eggs and larvae, blood smear microscopy of blood protozoa, body surface examination of ectoparasites and helminthological examination of endoparasites. The result showed that 31 species were identified, of which 3 species were trematodes, 2 species of tapeworm and metacercaria, 13 species of nematode, 9 species of spider insect and 4 species of protozoa. They belonged to 6 classes, 12 orders, 21 families, 27 genera. In view of the characteristics of invasion and transmission of Toxocara vitulorum and other serious parasitic diseases, the measures of programmed deworming and integrated control were formulated. According to the follow-up investigation, the marketing period of dewormed cattle were more than two months earlier than the non-dewormed cattle of the same age, and the selling price increased by more than 20%.
