摘要： 我们选用120羽0日龄的AA肉仔鸡,随机分为4组,每组设6个重复, 每个重复5羽鸡。研究大豆磷脂替代基础日粮(对照组)中0.5%、1%和1.5%的玉米对肉鸡生产性能和胴体品质的影响。结果表明,用大豆磷脂替代日粮中的玉米使肉鸡42日龄增重分别提高了2.1%、4.4%和8.7%;饲料转化率分别提高了3.5%、5.2%和8.1%;饲养成本分别下降了2.3%、3.5%和5.8%;胸肌率分别提高了14.7%、0.9%和-0.49%,腹脂率分别提高了11.06%、20.28%和44.7%。同时，我们又选用180羽健康AA肉仔鸡,随机分成6个处理组,每个处理6个重复,每个重复5羽鸡。A组为空白对照, B组为添加抗生素(黄霉素5mg/kg)试验组, C、D、E、F组分别为添加大豆活性肽0.2%、0.4%、0.6%、0.8% (固态,含活性肽40 g/kg)的试验组。试验结果表明:①在生产性能上,大豆活性肽可显著提高肉仔鸡日增重和采食量,在提高屠宰率方面也有一定的作用;②在经济效益上,大豆活性肽可以降低饲料成本,增加毛利润。试验证明,大豆活性肽可以有效应用于肉仔鸡生产中,其最适添加量为0.6%,优于使用抗生素(黄霉素5 mg/kg)。

Abstract: One hundred and twenty broilers were randomly divided into 4 groups with 6 replicates in each group and 5 chicken in each replicate. We studied influence on performance and body quality of broiler chicken by using soybean phoshatide to take the place of 0.5%,1% and 1.5% corn of basal daily grain. Conclusion indicated boiler chicken forty-two days adding weight improved 2.1%, 4.4% and 8.7%,feed changing rates raised 3.5%,5.2% and 8.1%, raising costs fell 2.3%,3.5% and 5.8%, chest muscle rates improved 14.7%,0.9% and -0.49%, belly fat rates improved 11.06%,20.28% and 44.75 by using soybean phoshatide to take the place of corn in daily grain. At the same time, one hundred and eighty broilers were randomly divided into 6 groups with 6 replicates in each group and 5 chicken in each replicate. Group A was the control Group, B, C, D, E and F were supplemented with antibiotic, 0.2%, 0.4%, 0.6% and 0.8% bioactive soybean peptide (BSP) respectively. The results showed that the BSP could improve daily weight gain, daily feed intake and slaughter rate, and save feed cost. The study indicated that BSP could be used in broiler production effectively and led to better results than anbiotic. The optimum amount of the supplement was 0.6%.
