摘要：

选取环江香猪128头，随机分为对照组、德氏乳杆菌（Lactobacillus delbrueckii，LD）组、低聚木糖（xylo-oligosaccharides，XOS）组、合生元（LD+ XOS）组。采血分离血浆，测定生化参数和氧化/抗氧化指标的变化。结果表明，试验第28天，LD、XOS和合生元组甘油三酯和羟自由基水平显著升高，谷胱甘肽过氧化物酶水平显著降低；试验第56天，合生元组总蛋白、白蛋白、尿素氮、葡萄糖、甘油三酯、胆固醇、低密度脂蛋白-胆固醇和肝脂酶水平显著升高，XOS组乳酸脱氢酶和总谷胱甘肽水平、合生元组丙二醛、天冬氨酸转氨酶和乳酸脱氢酶水平显著降低；试验第84天，LD、XOS和合生元组过氧化氢、天冬氨酸转氨酶和乳酸脱氢酶水平均显著降低，合生元组总蛋白和谷胱甘肽过氧化物酶水平显著升高。由此可见，饲粮添加LD或同时添加LD和XOS可调节机体营养代谢和氧化-抗氧化平衡。

Abstract:

A total of 128 Huanjiang mini-pigs were selected and randomly divided into four groups,including control,Lactobacillus delbrueckii (LD),xylo-oligosaccharides (XOS),and synbiotic (LD+ XOS) groups.Blood was collected to determine plasma biochemical parameters and oxidant-antioxidant indices.The results showed that,triglyceride and hydroxy radical levels in the LD,XOS,and synbiotics groups were increased;while glutathione peroxidase level was decreased on day 28 of the trial.On day 56 of the trial,total protein,albumin,urea nitrogen,glucose,triglyceride,cholesterol,low density lipoprotein-cholesterol,and hepaticlipase levels in the synbiotics group were increased;while lactate dehydrogenase and total glutathione levels in the XOS group,and malondialdehyde,aspartate aminotransferase,and lactate dehydrogenase levels in the synbiotics group were decreased.On day 84 of the trial,H2O2,aspartate aminotransferase,and lactate dehydrogenase levels in the LD,XOS,and synbiotics groups were decreased;while total protein and glutathione peroxidase levels in the synbiotics group were increased.Collectively,these findings suggested that dietary supplementation with LD and/or XOS could regulate the body′s nutritional metabolism and oxidant-antioxidant balance.

Key words: Huanjiang mini-pig, plasma biochemical parameters, metabolism, synbiotics, oxidant-antioxidant indices
