240 broilers were randomly divided into 2 groups, repetion for each group, feeded for 8 weeks. Feed preparation and feeding method were considered according to the requirement of broiler production system. With establishing nutrition supply model and modelling the rear growth cure of the broiler nutrition level for the treatment group were adjusted. NRC for broilers was used for the control group.

240 broilers were randomly divided into 2 groups, repetion for each group, feeded for 8 weeks. Feed preparation and feeding method were considered according to the requirement of broiler production system. With establishing nutrition supply model and modelling the rear growth cure of the broiler nutrition level for the treatment group were adjusted. NRC for broilers was used for the control group. The results showed that- the mean body weight of the treatment group at the end of 3wk, 6wk, 8wk (274. 34±37. 42g, 1095. 93 ± 104. 50g,1688. 46±112. 80g, respectively) was higher significantly (P<0. 01) than that of the control group (213. 26±18. 64g, 916. 34±37. 42g, 1516. 92±78. 09g, respectively). Feed converation ratio (2. 19 : 1) and the profit for each broiler of the treatment group was also higher than that of the control group. Based on the modelling of growth curve nutrition supply adjustment was able to increase the whole profit of broiler production system.

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±18.64g,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。
