Abstract

Abstract: 500 fecal samples of Yak in Kangding and Seda county were collected for epidemiological investigation of yak coccidiosis. Coccidia mean infection rate was 30.00%（150/500），Kangding and Seda county were 31.95%（54/169） and 29%（96/331） respectively. Male yak mean infection rate was 26.38%(43/163),female yak was 31.75%(107/337). The infection rate of adult dairy yak (＞3 years old)was 16.22%(42/259),young and calves dairy yak(＜3 years old)was 44.81%(108/241). Nine species of Eimeria coccidian were identified as follows: Eimeria bovis (24.00%),E.cylindrica(12.00%),E.zurnii(16.00%),E.subspherica(18.03%),E.brasilicnsis(8.27%),E.canadensis(6.67%),E.ellipsoidallis(9.33%),E.wyomingensis(3.30%) and E.auburncnsis(2.40%).
