摘  要:
选用20头体况和预产期相近的中国荷斯坦奶牛,随机分为4组,对照组喂基础日粮,3个处理组在基础日粮中分别添加2.4、4.8、7.2g/d的酵母铬。结果显示,与对照组相比,添加酵母铬可以提高外周血淋巴细胞转化能力,提高了IgM、IgG和IgA的含量(P<0.01)。结果表明,基础日粮添加2.4g/d的酵母铬,使DM铬添加水平为0.4mg/kg时,效果较好。

摘  要:
A total of 20 health Chinese Hosltein dairy cows with similar number of parturition and delivery date were randomly assigned to four different treatments.The four treatments were:(1)basal diet(the control,without any Cr addition);(2)basal diet+2.4g/d Cr-yeast;(3)basal diet+4.8g/d Cr-yeast;(4)basal diet+7.2g/d Cr-yeast.The experimental period was 2weeks,from the day of delivery to the 14 th day after delivery.The results showed that compared with the control group,with the supplement of Cr-yeast,peripheral blood lymphoid transformation,serum IgM,IgG and IgA concentration increased(P<0.01).Under the conditions of this experiment,we found that the basal diet with 0.4mg/kg Cr in DM which supplied in form of Cr-yeast(2.4g/d)had better improvement on immune function.
