【摘要】：试验旨在探讨微生物源性抗氧化剂对断奶仔猪生长发育和抗氧化能力的影响。选择12窝21日龄杜洛克×长白仔猪,随机分为2组,每组6窝(重复),对照组饲喂基础饲粮,试验组在基础日粮中添加20 g/kg的微生物源性抗氧化剂。试验从仔猪21日龄开始,27日龄断奶,至断奶后2周结束。结果表明,添加微生物源性抗氧化剂可显著提高仔猪采食量和日增重(P0.05),降低料重比(P0.05);显著提高仔猪断奶1周时血清SOD和GSH-Px活性以及血清NO水平(P0.05),显著降低血清MDA含量(P0.05)。由此可见,微生物源性抗氧化剂可以提高仔猪的抗氧化能力,减少断奶应激和氧化损伤,促进仔猪的生长发育。提示添加微生物源性抗氧化剂可有效减缓仔猪的断奶应激。
[Abstract]:The purpose of this study was to investigate the effects of microbial antioxidants on the growth, development and antioxidant capacity of weaned piglets. Twelve litters of 21-day-old Duroc 脳 Landrace piglets were randomly divided into two groups, 6 liters in each group. The control group was fed with basal diet. The experimental group was supplemented with 20 g/kg microbiological antioxidants in the basal diet. The experiment began at 21 days old and weaned at 27 days old until 2 weeks after weaning. The results showed that the supplementation of microbial antioxidants could significantly increase feed intake and daily gain of piglets, decrease feed / weight ratio (FW) P0.05N, significantly increase serum SOD and GSH-Px activity and serum no level (P0.05N) at 1 week weaning, and significantly reduce serum MDA content (P0.05N). Therefore, microbial antioxidants can improve the antioxidant capacity of piglets, reduce weaning stress and oxidative damage, and promote the growth and development of piglets. These results suggest that the addition of microbial antioxidants can effectively reduce weaning stress in piglets.
