药物氯丙嗪对麻羽肉种鸡产蛋性能的影响

Effect of Thorazine on Egg Production of Black-speckle Feather Breed-layer

为探讨氯丙嗪对优质肉种鸡繁殖性能的影响,将150只健康的36周龄麻羽肉种鸡D系父母代种母鸡随机分为5组,其中4个试验组饲喂氯丙嗪:试验1组至4组每鸡每天分别饲喂10 mg1、5 mg2、0 mg2、5 mg,连饲喂2 d停药5 d,再重复一次;对照组不使用氯丙嗪。结果表明:经药物处理的第1周,试验2组产蛋率显著提高,其他各组无明显提高。药物处理的第2周,试验1组产蛋率提高显著。用药2周内试验2组平均产蛋率提高,试验1组种蛋平均合格率下降,其他各组无显著差异。

In order to study the effect of Thorazine on egg production of black--speckle feather breed --layer, 150 healthy black--speckle feather breed--layers at 36 weeks were divided into five groups among which 4 experimental groups were used Thorazine： experimental group one 10mg per day, experimental group two 15mg per day, experimental group three 20mg per day, experimental group four 25mg per day, which is used for two successive days and stopped for 5 days and then repeat; the control isn＇t applied medicine. The result showed that in the first week of the treatment, the laying rate of experimental group 2 increased significantly, while others not. In the second week of the treatment, the laying rate of experimental group 1 increased significantly. The average laying rate of experimental group 2 elevated in two weeks and that of group 1 dropped, while without significant difference in other groups.
