摘 要:将一日龄艾维因肉仔鸡(雌雄各半)180只在同一舍内饲养,14日龄时将其随机分成4组,其中Ⅰ、Ⅱ组饲料按1%分别添加我们研制的方剂一和方剂二,连续用药15d,为药物预防组;Ⅲ组在饲料中按0.05%添加肾肿腹水消,连用7d(药品要求的预防剂量),为药物对照组;Ⅳ组饲料中不添加任何药物,为空白对照组。Ⅰ-Ⅳ组发病率分别为0、10%、3%和20%,42d时Ⅰ、Ⅳ组体重高于其它组,Ⅰ平均体重为1972.92g,Ⅳ组平均体重为1989.91g。试验表明方剂一为该试验条件下预防肉鸡腹水综合征最有效的方剂,其保护率可达100%,且不影响出栏重。对方剂一预防肉鸡腹水综合征的机理进行探讨。180 14-day-old broiler chicks (half male and half female) were randomly divided into 4 groups and reared in the same stall environment.The feed of group Ⅰ,Ⅱ and Ⅲ was added with drug No.1 for 15 days,drug No.2 for 15 days and a specific drug for ascites at a preventive dose for 7 days respectively,while group Ⅳ consumed no additives. The results showed that the morbidity rate of ascites in group Ⅳ was the highest while the rates in groups fed with drug additions were much lower,and there was no incidence of ascites in group Ⅰ.The average body weight of fattened broiler in group Ⅰ(1972.92g)very close to that of group Ⅳ( 1989.91g).In summary,the drug No.1 is the best prescription for preventing ascites syndrome in broilers.
