摘要
该试验旨在观察新研制的中药制剂百呼清药效。试验将人工感染鸡毒支原体的15日龄肉鸡,按常规方法随机分为6组,每组每天给药2次,连续5d,停药后继续观察10d。结果给药组增重显著或极显著高于感染对照组(P<0.05或P<0.01),但与健康组比较差异不显著(P>0.05);给药组均能明显降低抗体阳性反应率和减少气囊损伤记分,其中以高、中剂量组最明显,但各给药组间无显著差异。上述结果表明,百呼清对鸡毒支原体感染疗效显著,其作用优于或相当于泰乐菌素。
180 SPF AA broilers,15-day-old,were randomly divided into three different doses of Baihuqing treatment goups, tylosin treatment group,infection control group and normal control group.The birds artificially infected with mycoplasma gallisepticum（MG） were treated with Baihuqing at low,middle and high doses twice every day for 5 days.and sequelly observed for 10 days after treatment .The results showed that the body weight gains of treatment groups were remarkably（P〈0.05）kr extreme remarkably（P〈0.01）higher than that of infection control,and had no significant difference（P〉0.05）compared with that of health control.Meanwhile the antibody positive rate and air sac injury level of treatment groups was obviously reduced,especially the doses of high and middle,between which there were no obvious difference.It is concluded that Baihuqing has effect against MG which is better than or equal to tylosin.
