【摘要】 为了研究百球清(Toltrazuril)对猪等孢球虫病的治疗效果,用15mg/(kg.bw)和7.5mg/(kg.bw)2个剂量的百球清口服治疗感染猪等孢球虫(Isosporasuis)的7日龄仔猪,用粪便性状及腹泻持续时间、OPG值及排卵囊持续时间、增重率、死亡率及剖检病变等指标来判定百球清治疗效果。结果显示,首次给药后第5—6天给药组(Ⅰ、Ⅱ组)仔猪粪便性状全部恢复正常,首次给药后第3—4天Ⅰ、Ⅱ组仔猪粪便卵囊转阴率达100%,仔猪精神、食欲等明显好转,除Ⅰ组死亡1头外,组其余仔猪全部存活。Ⅰ、Ⅱ和Ⅲ组仔猪2周内增重率分别为65.1%、61.9%和34.7%,Ⅰ、Ⅱ组仔猪增重率提高显著(P<0.01)。而感染不给药组(Ⅲ组)仔猪首次给药后1周仍有少量卵囊排出,死亡2头,存活仔猪明显消瘦。表明百球清对仔猪等孢球虫病具有良好的治疗效果。更多还原
