摘　　要：通过对肉品质与生理生化指标的检测,研究不同的饲料添加剂产品对猪肉品质的影响。选取270头21日龄健康的断奶仔猪,随机分为5个处理组,每个处理6个重复,每个重复9头猪。正对照组(A)饲喂玉米-豆粕型基础日粮+抗生素,试验组(B、C、D、E)分别在不添加任何抗生素的基础饲粮中添加0.05g/kg乳球菌微生态制剂、0.25g/kg乳酸菌复合微生态制剂、0.334g/kg多酚复合添加剂和0.15g/kg酵母硒,试验期为138d。结果表明,乳球菌、乳酸菌、多酚与酵母硒作为饲料添加剂均可提高猪肉的肉色、嫩度与甜味、改善猪肉品质;也可在不同程度上提高机体的抗氧化能力,其中酵母硒效果最佳,乳酸菌次之,两者效果均好于乳球菌和多酚。The effects of different feed additives on pork quality were studied by testing the physiological and biochemical index.270 healthy weaned pigs of 21 days old,were randomly divided into 5 treatments with 6 replicates and 9 per replicate.The positive control group（A）was fed a basal diet supplemented with antibiotics,groups（B,C,D,E）were fed experimental diets supplemented with 0.05 g/kg Lactococcus probiotics（Enterococcus faecium）,0.25 g/kg compound probiotics（E.faecium and Lactobacillus plantarum）,0.334 g/kg polyphenol additives and 0.15 g/kg selenium yeast,respectively.The trial period was 138 days.Results showed that：diet supplementation with different feed additives could increase the brightness,tenderness and sweetness of pork.The antioxidant capacity was improved to varying degrees.Selenium yeast had the best effect and Lactobacillus took the second place,both were better than Lactococcus probiotics and polyphenol additives.
