摘　　要：为履行好寻甸县肉牛科技特派团职责,助推寻甸县“一县一业”肉牛产业示范县创建,打造世界一流“绿色食品牌”,推动高原特色农业高质量发展。2021-2022年云南省寻甸县肉牛科技特派团成员对寻甸县16个乡镇,29个肉牛养殖场(户),1个肉牛交易市场,1个屠宰场共采集654份粪便样品和899份全血样品进行了肉牛寄生虫的筛查。结果显示:29个养殖场的899份全血样品中检出巴贝斯虫阳性12份,阳性率为1.33%,阳性场5个,场阳性率17.24%;31个检测场点筛查654份粪便,共筛查出检出了线虫、吸虫、球虫、绦虫、螨虫5类寄生虫虫卵及卵囊,寄生虫总感染数176份,平均感染率为26.91%,其中球虫55份,感染率最高,为8.43%;吸虫47份,感染率为7.68%;牛带绦虫30份,感染率为4.60%;线虫32份,感染率为4.91%,疥螨12份,感染率为1.83%,混合感染的病例44份,占总感染病例的0.25%。阳性场27个,场总体阳性率为87.10%,其中吸虫场阳性率为58.06%;球虫场阳性率51.61%;线虫场阳性率48.38%;绦虫场阳性率38.71%,疥螨场阳性率25.80%。市场环节寄生虫感染率最高,为38.33%(23/60),养殖环节次之,为26.31%(151/574),屠宰环节最少,为10%(2/20)。部分乡镇感染率高;放牧牛群和犊牛感染率较高。本调查结果为寻甸县肉牛寄生虫防控提供了科学的参考依据,指导养殖户规范管理,制定科学的驱虫程序,强化环境消毒等防控措施,切实提高养殖效益和肉牛产品品质,为寻甸肉牛“绿色食品牌”打造贡献兽医力量。In order to fulfill the responsibilities of the Beef Cattle Science and Technology Mission in Xundian county,assist in the establishment of the"one county,one industry"beef cattle industry demonstration county in Xundian County,create a world-class"green food brand",and promote the high-quality development of plateau characteristic agriculture,members of the Xundian County Beef Cattle Science and Technology Mission in Yunnan Province from 2021 to 2022 collected 654 fecal samples and 899 whole blood samples from 16 townships,29 beef cattle farms(households),1 beef cattle trading market,and 1 slaughterhouse in Xundian County for screening of beef cattle parasites.The results showed that 12 out of 899 whole blood samples from 29 farms were positive for Babesia,with a positive rate of 1.33%.There were 5 positive farms,with a positive rate of 17.24%.654 fecal samples were screened from 31 testing sites,and 5 types of parasite eggs and egg cysts were detected,including nematodes,trematodes,coccidia,tapeworms,and mites.The total number of parasites was 176,with an average infection rate of 26.91%,including 55 coccidia,with the highest infection rate of 8.43%;47 trematodes,with an infection rate of 7.68%;30 taeniasis,with an infection rate of 4.60%;32 nematodes,with an infection rate of{4.91%};and 12 mites,with an infection rate of 1.83%.There were 44 mixed infections,accounting for 0.25%of the total infection cases.There are 27 positive fields,with an overall positive rate of 87.10%,among which the positive rate of the trematodes was 58.06%;the positive rate of coccidia was 51.61%;nematodes was 48.38%;apeworms was 38.71%,and mites was 25.80%.The highest infection rate was in the market segment,with a rate of 38.33%(23/60),followed by the breeding segment,with a rate of 26.31%(151/574),and the slaughter segment,with a rate of 10%(2/20).Some townships had high infection rates;grazing cattle and calves had higher infection rates.The results of this survey provide a scientific reference for the prevention and control of bee
