摘要
为了了解天祝白牦牛肠道寄生虫感染情况,笔者拟采用离心沉淀法、饱和盐水漂浮法及抗酸染色法对天祝3个采样点共252份白牦牛粪样展开调查。结果显示:天祝白牦牛肠道寄生虫感染率达100%,混合感染率达68.5%。共检出3种肠道寄生虫,以球虫与圆线虫为优势虫种,其感染率分别为75.4%和87%,且犊牛球虫感染率较成年牛高。阳性粪便中虫卵与卵囊均以轻度感染为主。
The aim of this study was to understand the prevalence of intestinal parasite in Tianzhu white yak.A total of 292 fecal samples from 3 natural pasture were examined using centrifugation method,saturated brine flotation method and acid-fast staining method.The results showed that the overall infection rate of intestinal parasites was 100% in white yaks and mixed infection rate was 68.5% .Three species of parasites was detected,including predominant coccidia and strongylidae spp with the prevalence of 76% and 78% ,respectively.Furthermore,the infection rate of coccidia in calves is higher than adult cattle.The present results suggested that the positive fecal eggs and oocysts were mainly mild infection.
