0
()
摘要:
对安徽省正阳关鸡场200个粪样采用饱和白糖溶液漂浮法进行鸡球虫感染情况的调查,结果表明:肉鸡球虫感染率为46.1%(83/180),而肉种鸡球虫感染率为70.0%(14/20)。所获虫种经鉴定为堆型艾美耳球虫(Eimeria acervulina)、和缓艾美耳球虫(E.mitis)、巨型艾美耳球虫(E.maxima)、柔嫩艾美耳球虫(E.tenella)和毒害艾美耳球虫(E.necatrix)。用SAS系统对调查数据进行统计分析,肉鸡球虫感染率存在年龄差异,相同日龄肉鸡毒害艾美耳球虫感染率显著低于其他几种球虫。

fecal specimens from Zhengyangguan farm in Anhui Province were examined with Sheather`s sucrose floating method.The results showed that the rate of meat chicken Eimeria was 46.1%(83 specimens out of 180), and the rate of meat-breeding chicken Eimeria was 70.0%(14 specimens out of 20). They were confirmed to be E.acervulina,E.mitis, E.maxima, E.tenella and E.necatrix,respectively.SAS system analysis indicated that there was a significant difference between E.necatrix and other Eimeria.
