[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.
