摘　　要：【目的】为了研究益生菌和植物多糖对圈养山羊抗氧化性能和肉品质的影响。【方法】选取40头4月龄健康母羔羊,随机分为4组,每组10头羊,分别为对照组、益生菌组、植物多糖组和复合组(益生菌+植物多糖)。试验期为期70 d,其中预试期10 d,正试期60 d。【结果】与对照组相比,在正试期的第60天,益生菌组和植物多糖组的血清总抗氧化能力(T-AOC)、超氧化物歧化酶(SOD)和谷胱甘肽过氧化酶(GSH-Px)显著升高(P<0.05),丙二醛(MDA)含量显著降低(P<0.05),复合组血清的GSH-Px含量显著升高(P<0.05)。益生菌组、植物多糖组和复合组的肌肉滴水损失均显著低于对照组,但益生菌组和植物多糖组的肌肉水分含量比对照组显著升高(P<0.05),肉色b*值显著低于对照组(P<0.05)。【结论】饲料中添加益生菌、植物多糖可提高圈养山羊的抗氧化功能、改善宰后羊肉品质。[Objective]This study aimed to study the effects of probiotics and plant polysaccharides as feed additive on serum antioxidant and meat quality incaptive goats.[Method]Forty healthy female goats aged 4 months were selected in this study and randomly divided into 4 groups,10 goats in each group,respectively as control group,probiotics group,plant polysaccharides group and compound group.The pre-feeding period was10 days and the trial period was 60 days[.Result]The results showed as follows:on day 60th,dietary supplemental with probiotics or plant polysaccharides increased the activity of antioxidant(T-AOC,T-SOD and GSHpx)(P<0.05),but decreased the content of malondialdehyde(MDA)(P<0.05).GSH-Px activity in compound group increased significantly(P<0.05).The muscle drip loss of the probiotics group,plant polysaccharides group and compound group were significantly lower than that of the control group,but the muscle moisture content of the probiotics group and plant polysaccharides group was significantly higher than that of the control group(P<0.05)and the b*value of meat color was significantly lower than that of the control group(P<0.05).[Conclusion]The results indicated that dietary supplemented with probiotics or plant polysaccharides enhanced the antioxidant capacity of serum,and improved the meat quality of captive goats.
