【摘要】 将102头预产母牛随机分为4组,分别接受亚硒酸钠维生索E,维生素A、D维生素E和空白处理。结果,其胎衣滞留率依次是17％,48％,39％,44％处理间百分率差异显著(P<0.05)。处理间相互比较结果,亚硒酸钠维生素E与其他3组间差异均显著(P<0.05),而其他3组间差异均不显著。表明亚硒酸钠维生素E预防奶牛胎衣滞留效果明显。更多还原

【Abstract】 A total of 102 parturient cows were divided randomly into 4 groups and fed with sodium selenite-vitamin E mixture, vitamin AD, vitamin E anp basal diet. Result showed the incidence of retained placenta was 17％, 48％, 39%, 44% respectively. The difference between the percentage of groups was significant (P<0.05) . The group treated with sodium selenite-vitamin E mixture was significantly different from each of the other three groups (P<0.05)which were not different each other significantly. It is clear that sodium selenite-vitamin E mixture reduces incidence of retained placenta effectively.更多还原
