摘  要：
为研究苜蓿黄酮对奶牛血液生化指标、抗氧化性能和免疫的影响,选取4头装有瘘管的头胎荷斯坦奶牛,试验采用4×4拉丁方设计,每组奶牛饲喂混合日粮中分别添加0g(Ⅰ组)、20g(Ⅱ组)、60g(Ⅲ组)和100g(Ⅳ组)的苜蓿黄酮。试验期为4期,每期24d。结果显示:1)血清的总蛋白含量随苜蓿黄酮添加剂量的升高呈二次曲线变化,出现先下降后升高(P<0.05)趋势,但其他指标没有影响;2)苜蓿黄酮组血液中的血小板数量(P<0.05)和血小板压积(0.05

摘  要：
The objective of this study was to examine the effects of flavonoids from alfalfa on blood biochemical indexes,oxidation resistance and immunity of dairy cows.Four primiparous Holstein cows fitted with ruminal cannulas were selected.4×4Latin square design was used in the experiment and the cows were fed total mixed ration added 0,20,60 or 100g alfalfa flavonoids at different periods,respectively.The experiment had four experiment periods and each period contained 24 days.The results showed:1)The total protein content of serum appeared change of quadratic curve,and was decreased at first and then increased with increasing doses of alfalfa flavonoids extract(AFE)(P<0.05).The other indexes were not affected by AFE;2)Platelet counts(P<0.05)and thrombocytocrit(0.05
