摘　　要：将２４０只ＡＡ商品代肉用仔鸡随机分为两组，每组设两个重复，按肉用仔鸡生产系统设计主要环节，８周饲养．建立营养供给模型，准确模拟试验组肉鸡实际生长以调整营养供给水平，对照组按ＮＲＣ标准配制日粮．实验结果表明：３、６、８周龄，试验组平均体重（２７４．３４±３７．４２ｇ，１０９５．９３±１０４．５０ｇ，１６８８．４６±１１２．８０ｇ）与对照组（２１３．２６±１８．４６ｇ，９１６．３４±３７．３２ｇ，１５１６．９２±７８．０９ｇ）相比差异极显著．试验组饲料转化率（２．１９：１），高于对照组（２．４０：１）．鸡只纯收益（１．７４元）高于对照组（１．４９元）．根据肉用仔鸡实际生长情况调整营养供给水平，能进一步挖掘肉鸡饲养效益．broilers were randomly divided into 2 groups,repetion for eachgroup,feeded for 8 weeks.Feed preparation and feeding method were consldered ac-cording to the requirement of broiler production system.With establishing nutritionsupply model and modelling the rear growth cure of the broiler nutrition level for thetreatment group were adjusted.N KC for broilers was used for the control group.Theresults showed that:the mean body weight of the treat menl group at the end of 3wk,6wk,8wk(274.34±37.42g,1095.93±104.50g,1688.46±112.80g, respectively)washigher significdntly(P<0.01)than that of the control grouo(213.26±18.64g,9l6.34±37.42g,1516.92±78.09g,respectively).Feed converation ratio(2.19:1)and theprofit for each broiler of the treatment group was also higher than that of the controlgroup.Based on the modelling of growth curve nutrition supply adjustment was able toincrease the whole profit of broiler production system.
