摘要
选用180只爱拔益加肉仔鸡,采用单因子随机试验设计,分成6个处理,每个处理6个重复,每个重复5只鸡。处理组A饲喂基础日粮;处理组B饲喂基础日粮+抗生素(黄霉素5mg/kg);处理组C、D、E、F分别饲喂基础日粮+大豆活性肽0.2%、0.4%、0.6%、0.8%(液态,含活性肽40g/kg)。结果表明,大豆活性肽添加剂可以提高蛋白质代谢率。E和F组的蛋白质代谢率分别比A组提高了2.66%和2.41%(P<0.05)。随着大豆活性肽添加浓度的提高,肉仔鸡日增重加快,饲料转化率提高。E组的日增重比对照组高2.89g(P<0.01),比抗生素组高1.84g(P<0.01)。E组料肉比比对照组低0.17(P<0.05)。
One hundred and eighty AA broilers were randomly divided into 6 groups with 6 repetition in each group and each group included 5 chicken. Control group A was fed with basal diets. Antibiotic,0.2%,0.4%,0.6% and 0.8% bioactive saybean peptides （BSP）were added to group B,C,D,E and F basal diets respectively. The results showed that BSP could enhance the rate of protein metabolism,that of group E and F were increased by 2.66% and 2.41% compared with control group（P〈0.05）. The more dosages of BSP were fed,the faster daily growth and the higher feed conversion rate were found. Daily gain of group E was improved 2.89g and 1.84g compared with control（P〈0.O1）and antibiotics group（P〈 0.01）respectively. Feed converison of group E was 0.17 lower than that of control（P〈0.05）.
