目的】：本试验通过比较相同品种、相同体况的商品蛋鸡采食不同蛋白能量水平的配合饲料后生产性能的差异,筛选出最适合该蛋鸡品种的蛋白能量水平的配合饲料.为以后的生产管理中降低配方成本、改善饲料品质、提高经济效益提供参考.方法：试验选用550只500日龄的罗曼粉蛋鸡,随机分为3个处理组A、B、C,每处理五个重复,日粮分别为A的高能低蛋白（能量2580 Kcal/kg,蛋白16.96%）B的高能高蛋白（能量2580 Kcal/kg,蛋白17.17%）,C的低能高蛋白（能量2540 Kcal/kg,蛋白17.27%）.试验时间为31天.【结果】：高能低蛋白组,高能高蛋白组和低能高蛋白组在试验期的试验结果为：产蛋率89.82%、91.04%、89.93%.采食量113.2g、114.6g、114.7g.蛋重54.77g、55.03g、54.98g.料蛋比2.067、2.183、2.086.经统计分析,

Objective】: In this experiment, comparing the same species, the same body condition of the commercial layer feed with different protein and energy levels of the differences in performance after the feed, selected the most suitable varieties of the egg protein and energy levels of the feed. For the future management of lower production cost formula to improve feed quality, increase economic efficiency reference. Methods: The test used 550 days of the Roman powder 500 laying hens, were randomly divided into three treatment groups A, B, C, each treatment five repeated A\u0026#39;s high-energy diets were low protein (energy 2580 Kcal / kg, protein 16.96%) B of the high-energy high-protein (energy
