不同剂量克罗米芬对丝羽乌骨鸡产蛋性能的影响

Effect of Clomifene Citrate with Differ Dosage on Laying Performance of Silky Fowl Hens

试验旨在了解不同剂量克罗米芬(clomifene citrate)对丝羽乌骨鸡产蛋性能的影响。将120只丝羽乌骨鸡随机分为4组。试验1组每只鸡每天口服克罗米芬15 mg,试验2组每只鸡每天口服20 mg,试验3组每只鸡每天口服25 mg,第4组为对照组,不使用药物。药物使用方法为每天的药物研碎后添加在12∶00饲喂的日粮中喂服。药物使用疗程为每7 d为一个疗程,连续喂服2 d、停药5 d,共使用2个疗程。结果表明,不同添加剂量的克罗米芬不影响丝羽乌骨鸡的产蛋率和种蛋合格率,但能够减弱抱窝个体的发生。

The study was conducted to investigate the effect of clomifene citrate dosage on laying performance of silky fowl hens. 120 birds were allocateded to 4 treament groups randomly. The clomifene citrate was added to diet at 12 ： 00 PM every day after grind. The birds were supplement with clomifene citrate at 0, 15, 20, 25 mg/day.
