摘　　要：【目的】探讨亚甲基水杨酸杆菌肽对断奶仔兔血清和肠道组织抗氧化指标的影响。【方法】将300只35日龄断奶的新西兰白兔根据不同饲粮添加成分,分为5个处理组,分别是亚甲基水杨酸杆菌肽(BMD)高、中、低剂量添加组(100、50、25 mg/kg),杆菌肽锌(BZ)对照组(50 mg/kg)、空白对照组(无添加)。饲喂35 d后测定血液和肠道中抗氧化功能相关指标。【结果】与空白对照组相比,BMD和BZ显著提高了血清和肠道中总抗氧化能力(T-AOC)和超氧化物歧化酶(SOD)活性(P<0.05),显著降低了丙二醛(MDA)含量(P<0.05),BMD组和BZ组无统计学差异(P>0.05)。【结论】日粮中添加BMD可提高断奶仔兔的抗氧化功能,且以100 mg/kg的添加量最适宜。[Purpose]In order to investigate the effect of bacitracin methylene disalicylate on serum and intestine antioxidant indicators in weaning rabbits.[Method]300 New Zealand White rabbits were weaned at the age of 35 days,and randomly distributed into five groups according to different diets,there were bacitracin methylene disalicylate high dose group(BMD-H,100 mg/kg),BMD middle dose group(BMD-M,50 mg/kg),BDM low dose group(BMD-L,25 mg/kg),bacitracin zinc control group(BZ,50 mg/kg),blank control group(BC,no addition).After 35 days of feeding,the antioxidant indicators in the serum and intestine were detected.[Result]The levels of total antioxidant capacity(T-AOC)and superoxide dismutase(SOD)in serum and intestine of BMD group and BZ group were significantly higher than those in BC group(P<0.05).The contents of malondialdehyde(MDA)of BMD group and BZ group were significantly lower than BC group(P<0.05),and there were no statistical difference among BMD group and BZ group(P<0.05).[Conclusion]The basal diet supplemented with bacitracin methylene disalicylate could improve the antioxidant function of weaning rabbits,and 100 mg/kg feed additive was the best.
