大豆磷脂在肉鸡饲料中的应用研究

选用120羽1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1%、2%、3%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%。

Research on application of soybean phoshatide in feed of boiler chicken

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 1%、2%、3% 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 44.7% by using soybean phoshatide to take the place of corn in daily grain.
