黄芪茎叶微粉对蛋用公鸡雏生长及免疫器官指数的影响

为了探讨日粮中添加黄芪茎叶微粉对蛋用公鸡雏生长及免疫功能的影响。选择1日龄海兰褐公鸡雏96只，随机分成4处理组（其中有1个对照组和3个试验组）。对照组饲喂基础日粮，试验组在基础日粮中添加0.5%、1%、2%的黄芪茎叶微粉。试验期35天。结果表明：随着黄芪茎叶微粉添加量增多，公鸡雏体重、免疫器官指数均有不同程度的提高。说明黄芪茎叶微粉能提高蛋用公鸡雏的生长速度和增强免疫的功能。

Effects of Micropowders of Stalks and Leaves from Radix Astragali on Growth Performance and the Immune Organ Index in Laying Baby Male Chicks

In order to study the effects of micropowders of stalks and leaves from Radix Astragali added into daily ration on growth performance and the immune organ indices in laying baby male chicks, Ninty six 1-day hyline brown male chicks were chosen and then were randomly assigned into four treatment groups (including a control group and three experimental groups). The chicks from control group were fed basal diet and the ones from experimental groups were fed the feeds to which 0.5%, 1%, 2% micropowders of stalks and leaves from Radix Astragali were added respectively during 35 days breeding period. The results showed that the body weights and the immune organ index of male chicks all increased to varying degrees along with the more amount of micropowders of stalks and leaves from Radix Astragali. The results indicated that micropowders of stalks and leaves from Radix Astragali could improve the growth performance and immunity function of egg-type young cockerels
