【摘要】 为调查四川地区肉鸡球虫病流行现状,并筛选抗肉鸡球虫的有效药物,我们开展了本试验。结果表明,四川地区肉鸡球虫病感染场阳性率达95.24%,流行的球虫种类为柔嫩艾美耳球虫、和缓艾美耳球虫、毒害艾美耳球虫和巨型艾美耳球虫;妥曲珠利和磺胺氯吡嗪钠可溶性粉比复方磺胺氯吡嗪钠预混剂的短期驱虫效果更好,但复方磺胺氯吡嗪钠预混剂的药效维持时间比前两种药物更长。更多还原

【Abstract】 In order to know the broiler′s cocidiosis situation and screen anticoccidial drugs,we carried out this experiment. The result showed that the positive rate of chicken coccidiosis in Sichuan farms was 95.24%,the prevalent coccidial species were E. tenella,E. mitis,E. necatrix and E. maxima. Three drugs could cure coccidiosis effectively, the toltrazuril and sulfachloropyrazine sodium soluble powder expelling oocyst effectively earlier than compound sulfachloropyrazin sodium premix,but the latter′s effective period of anticoccidial was longer than that of the two former.更多还原
