摘　　要：试验选用 4 8头 15kg左右的杜大长或杜长大三元杂交猪 ,分 3个处理组即对照组、小肽组、小肽 +微生态复合组。饲养试验划分为 15～ 30kg、30～ 6 0kg、6 0～ 90kg三个阶段 ,在每阶段中期进行消化试验 ,饲养试验结束时进行屠宰试验 ,以测定胴体性状、猪肉品质、药物残留。结果表明 :小肽能提高肉猪生长速度 ,降低料重比 ,能替代抗生素和抗菌药物添加剂 ;小肽 +微生态对肉猪的促生长效果和经济效益要优于小肽单独使用 ;小肽、小肽 +微生态能提高饲料蛋白质的消化率 ;小肽、小肽 +微生态对猪胴体性状、猪肉品质和猪肉营养成分的影响不显著 ,但系水力、熟肉率有提高的趋势 ;小肽、小肽three way cross bacon type pigs with starting weight 15 kg of Duroc×Landrace×Large White or Duroc×Large White×Landrace were randomly divided into control group, Small Peptide supplemented group and the combination of Small Peptide and probiotics group. The feeding trail was divided into three growing stages: 15 30 kg, 30 60 kg ,60 90 kg. Digestion trail was conducted in the middle period of each growing stage to determine the digestibility of protein and energy. Two pigs of each replicates were slaughtered at the end of the trail to analyze the carcass characteristics, the meat quality, and do an analysis test to determine the component of meat and physical chemical index of the remains.The results showed that: Small peptide increased the daily weight gain and decreased ratio of feed to gain. Small peptides preparation could be an alternative of antibiotic. Combined supplementation of small peptides preparation and probiotics had better effects on growth than small peptides supplementation only. small peptide or the combination of Small Peptide and probiotics could increased the digestibility of protein.small peptide or the combination of Small Peptide and probiotics had no significant effect on the carcass characteristics, the meat quality, the component of meat. But holding capacity and cooked meat percentage seemed to increased in small peptide group and combination group.Addition of small peptide or the mixture of peptides and probiotics could ensure meat security.
