摘要
为探讨在饲料中添加不同剂量的党参对蛋鸡生产性能的影响,将党参粉碎后分别按0.25%0、.5%、0.75%、1%4个剂量水平添加于蛋鸡饲料中进行试验。结果显示,4个剂量的党参对蛋鸡的生产性能均有一定提高作用。其中,0.5%剂量水平的效果最佳,产蛋率较对照组平均增加4.37%,产蛋高峰(88%以上)维持近1.5个月,蛋重平均增加1.175 g,料蛋比降低了0.26%。
To explore the effects of different doses of Codonopsis pilosula on production performance of layer chicken,Codonopsis pilosula at level of 0.25%,0.5%,0.75% and 1% was added in the layer chicken feeding respectively.The results showed that egg productivity of layer chicken all improved at all dose levels.Among them,0.5% group was the best,which could enhance 4.37% of egg production rate than that of control group,the egg production peak（over 88%） maintained nearly 1.5 months,the egg weight increased by 1.175 g averagely,feed/egg ratio reduced by 0.26%.
