金华地区部分规模猪场哺乳仔猪球虫感染情况调查

Investigation of Coccidia Infection of Suckling Piglets in Jinhua Area

为了掌握浙江省金华地区规模猪场的球虫病感染情况。以便制定相应的猪球虫病防治措施．采用饱和盐水漂浮法对金华地区14个规模猪场哺乳仔猪球虫感染情况进行调查。统计结果：不同季节猪场哺乳仔猪球虫感染阳性率64．28％～71．43％，平均66．07％；样品阳性率25．59％—27．93％，平均26．91％，不同季节猪场阳性率和样品阳性率均无显著性差异；腹泻样品和不腹泻样品球虫阳性率分剐为26．99％-28．72％和9．39％-20．59％，差异板显著（P〈O．01）；3—22日龄仔猪球虫阳性率12．97％-33．54％，平均阳性率9-21日龄相对较高，15—16日龄最高。表明规模猪场哺乳仔猪球虫感染普遍存在。9～21日龄阳性率相对较高。

The coccidia infection of piglets was investigated in 14 scale barns in Jinhua area, the results： the coccidia positive rate in piglets （CPRP） during different seasons was 64.28%-71.43% （66.07% in average）, CPRP in samples was 25.59%-27.91% （26.91% in average）, where was no significantly different. The CPRP in diarrhea and no diarrhea samples was respectively 26.99%-28.72% and 9.39%-20.59% （with significantly different, P〈0.01）.
