摘要: 试验在海南和牛日粮中添加不同水平的维生素A,研究其对海南和牛血液生化指标和抗氧化性的影响。选体重和胎次相近的海南和牛12头,随机分为4个处理组,每个处理组设3个重复,每个重复1头牛,对照组饲喂干稻草基础日粮,试验组在对照组日粮基础上分别添加2500、5000、7500 IU/kg维生素A,试验期为40 d。结果表明:①维生素A的添加水平对海南和牛的血清抗氧化性指标的影响差异不显著(P>0.05),但随着日粮中维生素A添加水平的提高,海南和牛的血清抗氧化能力逐渐增强;②维生素A的添加水平可显著提高血液中葡萄糖的含量(P<0.05),同时随着维生素A添加水平的提高还可以提高血液中一些关键酶的活性(P>0.05)。因此,日粮中添加维生素A可以提高海南和牛血液中一些关键酶的活性和血清的抗氧化能力,并以添加7500 IU/kg组效果最好。

Abstract: This experiment was undertaken to investigate the effects of vitamin A levels on serum antioxidant indexes and blood biochemical indexes of Hainan-Japanese cattles. Twelve Hainan-Japanese cattles with average initial weight of(148.17±15.52) kg and the same genetic backgrounds were randomly divided into four treatments. Cattles were fed on white corn-soybean basal diet as the control group, the experimental groups were fed on additional 2500, 5000, 7500 IU/kg vitamin A into their own variations and basic feedstuff. The trial lasted for 40 days.The results showed that the levels of vitamin A had no significant infuence on serum antioxidant indexes of Hainan-Japanese cattles(P>0.05), but the vitamin A levels could increase the content of SOD and T-AOC in serum; the supplementation of vitamin A significantly increased the levels of glucose in blood(P<0.05), and some of the key enzymes activity increased too(P>0.05). In conclusion, some key enzyme activity in blood and serum antioxidant capacity could be improved by increasing the vitamin A levels in diets, the supplementation of vitamin A 7500 IU/kg was the best.
