【摘要】：试验旨在研究日粮中添加番茄渣发酵饲料对围产期奶牛抗氧化性能的影响。选择体质均匀,预产期、体重、胎次和泌乳量相近的围产期奶牛16头,随机分为2组,每组8头,对照组饲喂常规全混合日粮(TMR),试验组在日粮中添加番茄渣发酵饲料(围产前期13%,围产后期11%)。预试期14d,正试期60d(产前30d至产后30d)。结果显示,与对照组相比,围产后期试验组奶牛产奶量显著提高(P0.05);整个试验阶段,试验组奶牛血清GSH-Px、T-SOD和T-AOC活力均高于对照组,其中,围产前期试验组GSH-Px、T-SOD和T-AOC活力显著提高(P0.05),与围产前期相比,围产后期GSH-Px、T-SOD和T-AOC活力等抗氧化指标均呈下降趋势,围产后期试验组奶牛MDA含量较对照组显著降低(P0.05),但围产前期和围产后期间无显著差异(P0.05);与对照组相比,围产后期试验组红细胞、血红蛋白浓度、尿素氮、低密度胆固醇、铁含量均显著提高(P0.05);其他指标两组间差异均不显著(P0.05)。综上所述,日粮中添加番茄渣发酵饲料对围产期奶牛机体的抗氧化性能和产奶量有一定提高作用。
[Abstract]:The purpose of the experiment was to study the effect of tomato residue fermentation feed on antioxidant performance of perinatal dairy cows. Sixteen perinatal cows with uniform constitution, due date of delivery, body weight, birth order and lactation quantity were randomly divided into 2 groups with 8 cows in each group. The control group was fed with conventional total mixed diet (TMR),). In the trial group, tomato residue was added to the diet (13% in perinatal period and 11% in late perinatal period). The pretest period was 14 days and the current test period was 60 days (30 days before and 30 days after birth). The results showed that the milk yield in the later perinatal test group was significantly higher than that in the control group (P0.05). During the whole trial period, the activities of serum GSH-Px,T-SOD and T-AOC in the experimental group were higher than those in the control group. Among them, the activities of GSH-Px,T-SOD and T-AOC in the pre-perinatal test group were significantly increased (P0.05), compared with the pre-perinatal period. The antioxidant indexes such as GSH-Px,T-SOD and T-AOC activity decreased in the later perinatal period, and the MDA content in the later perinatal test group was significantly lower than that in the control group (P0.05). But there was no significant difference in perinatal period and perinatal period (P0.05). Compared with the control group, the erythrocyte, hemoglobin concentration, urea nitrogen, low density cholesterol, iron content in the later perinatal test group were significantly increased (P0.05); the other indexes between the two groups were not significant (P0.05). To sum up, adding tomato residue to the diet can improve the antioxidant performance and milk yield of perinatal dairy cows.
