摘　　要：选用体重为(20±0.5)kg的"杜×长×大"杂交仔猪,随机分为5组:对照组饲喂普通全价饲料;BS10组饲喂0.1%植物乳杆菌BS10发酵饲料;JJB3组饲喂0.1%乳酸杆菌JJB3发酵饲料;H组饲喂1.0%乳酸杆菌H发酵饲料;BB组饲喂0.1%乳酸杆菌BB发酵饲料。每组4个重复,每个重复3头猪。饲喂136 d后分析猪的生长性能、猪肉品质及血清抗氧化性能。结果表明:在生长期,各乳酸杆菌试验组猪的生长性能与对照组的差异均无统计学意义(P>0.05);在肥育期,各乳酸杆菌试验组猪的生长性能均显著优于对照组(P<0.05);JJB3组和BB组猪的肉色显著优于对照组(P<0.05);各乳酸杆菌试验组猪的滴水损失均低于对照组(P>0.05),BS10组和JJB3组猪的肌肉剪切力显著低于对照组(P<0.05);各乳酸杆菌试验组猪血清中超氧化物歧化酶(SOD)活性均显著高于对照组(P<0.05),过氧化氢酶(CAT)与谷胱甘肽过氧化物酶(GSH–Px)活性均高于对照组(P>0.05),而丙二醛(MDA)含量显著或极显著低于对照组。以上结果表明,乳酸杆菌发酵饲料能够提高猪的生长性能,改善猪肉品质,增强血清抗氧化性能。Piglets weighing （20±0.5） kg were divided into 5 groups with 4 repeats for each group and 3 pigs for each repeat. Pigs in control group were fed with basal diets, in BS10 group with plant-associated lactic acid bacteria strain BS10 （0.1%） fermented feed, in JJB3 group with lactic acid bacteria strain JJB3 （0.1%） fermented feed, in H group with lactic acid bacteria strain H （0.1%） fermented feed, and in BB group with lactic acid bacteria strain BB （0.1%） fermented feed. At 136 days after feeding, growth performance, meat quality and serum antioxidant activities were analyzed. The results showed that there was no significant difference （P〉 0.05） in growth performance of pigs in growing stage between the Lactobacillus groups and the control group while the growth performance were significantly better in Lactobacillus groups （P 〈0.05） in fattening stage. The color of flesh of pigs in JJB3 group and BB group were significantly better than that in the control group （P〈0.05）, the drip loss in Lactobacillus groups were lower than that in the control group （P〉0.05） and the shear forces in BS10 group and JJB3 group were significantly lower than that in the control group （P〈0.05）. In Lactobacillus groups, activities of superoxide dismutase （SOD） were all significantly higher （P〈0.05）, activities of catalase （CAT） and glutathione peroxidase （GSH-Px） were higher （P〉0.05）, and the content of malondialdehyde （MDA） was significantly （P〈0.05） or highly significant （P〈0.01） lower, compared to the control group. The results showed above indicating Lactobacillus fermented feed improves growth performance, meat quality and antioxidant activities of pigs.
