夏季扬州地区小规模黄羽肉鸡养殖场寄生虫感染情况调查

Investigation on Infectious Conditions of Parasites in small-scale yellow broiler farms of Yangzhou in Summer

本调查旨在了解扬州地区小规模黄羽肉鸡养殖场寄生虫感染情况。对扬州6个小规模黄羽肉鸡养殖场进行调查,调查对象分别为30、72日龄黄羽肉鸡,每个日龄调查3个场,每个场各随机取10份粪便样、肠道样和血样进行检测。结果显示:6个小型养殖场肉鸡主要感染球虫和螨虫,未感染线虫、绦虫、住白细胞虫等其他寄生虫;其中球虫感染率达71.7%,主要感染对象为30日龄肉鸡,感染部位以盲肠为主,其次为小肠;螨虫感染率为30%,主要感染对象为72日龄肉鸡。综上所述,夏季扬州地区小规模黄羽肉鸡养殖场要加强球虫、螨虫的防治措施。
