| 摘要：为探讨在蛋鸡饲料中添加不同剂量的党参对蛋鸡生产性能的影响，本试验分别将党参粉碎后按0.25%、0.5%、0.75%和1%4个剂量水平添加于蛋鸡饲料进行试验。结果显示，4个剂量的党参对蛋鸡的生产性能均有提高作用，其中0.5%剂量水平的效果最佳，产蛋率较对照组增加6个百分点，产蛋高峰（88％以上）维持达近1.5个月，蛋重平均增加1.929g，料蛋比降低了0.2。 |

| Abstract:
To explore the effects of different dose of Codonopsis pilosula added in forage of layer chicken on egg productivity, Codonopsis pilosula was added in the forage of layer chicken at 0.25%、0.5%、0.75% and 1% of feedings ,respectively. It is showed that egg productivity of layer chicken all improved at all dose levels, with the best results at 0.5%, which had a laying rate increasing by 6% comparing the control, the egg peak(over 88%) maintaining nearly 1.5 months, the egg weight increasing by 1.929g, feed/egg reducing by 0.2.
