摘要:
为研究葡萄籽原花青素(GSP)对断奶仔猪生长性能、血液指标及肠道损伤的影响,选择144头21日龄苏农黑猪,随机分为3个处理组,即哺乳对照组、断奶对照组及断奶试验组,每组6个重复,每个重复8头哺乳仔猪。哺乳对照组采食母乳,断奶对照组和断奶试验组分别饲喂基础日粮及含有100 mg/kg GSP的试验日粮。试验期共计 7 d,结束时采集血液与空肠样本,用于生化指标检测。结果表明:(1)断奶导致仔猪21~28日龄平均日增质量显著降低(P<0.05),但日粮添加GSP对仔猪断奶后1周内的生长性能无显著影响(P>0.05)。(2)断奶对照组血液D-木糖含量和血浆超氧化物歧化酶(SOD)活性较哺乳对照组显著下降,而血浆二胺氧化酶活性与丙二醛(MDA)含量较哺乳对照组显著升高(P<0.05);经GSP干预后,上述现象得到明显改善(P<0.05)。(3)与哺乳对照组相比,断奶对照组空肠绒毛高度(VH)及其与隐窝深度的比值明显下降,黏膜SOD活性与还原型谷胱甘肽含量显著降低,黏膜MDA含量显著增多(P<0.05);与断奶对照组相比,饲喂GSP试验日粮的断奶仔猪空肠VH和黏膜SOD活性均得到明显提高,黏膜MDA含量显著减少(P<0.05)。(4)断奶显著抑制了断奶仔猪空肠超氧化物歧化酶2(SOD2)转录水平,上调了肿瘤坏死因子α和白细胞介素6 mRNA丰度(P<0.05);GSP显著提高了断奶仔猪空肠还原型辅酶Ⅰ/Ⅱ依赖性醌氧化还原酶1和SOD2 mRNA表达水平(P<0.05),但未影响细胞因子转录表达(P>0.05)。综上可知,日粮添加GSP可有效提高断奶仔猪血浆抗氧化能力,缓解肠道损伤并改善黏膜氧化还原状态。
