摘　　要：选择不同日粮类型肉牛养殖户10户,参试生长母牛36头,参照肉牛营养需要和饲养标准,设计不同全株玉米青贮饲粮组合及日粮配方.随机分为3个试验组和1个对照组,试验Ⅰ组、Ⅱ组和Ⅲ组,按规范化全株玉米青贮+氨化麦草等多元化日粮进行科学饲养,Ⅳ组(对照)按传统的"有啥喂啥"方法饲喂,同期进行了饲养试验研究.结果表明:试验Ⅰ组、Ⅱ组和Ⅲ组,平均每头日增体质量效果均比Ⅳ组、(对照)有明显提高(P<0.01).试验Ⅰ组、Ⅱ组和Ⅲ组全株玉米青贮饲粮组合及日粮配方为较理想的肉牛生长母牛日粮优化配方.36 growing cows fed with different diets were selected from 10 farm households. The diets of different ingredients and formulas with whole corn silage were designed according to nutrient requirements and feeding standard of beef cattle. 36 growing cows were divided into 3 experimental groups and 1 control group at random. E I, E II and E Ⅲ group were fed with whole corn silage plus ammonification wheatgrass. Control group were fed what the farm households had on hand. The results indicated that the average daily weight gain per cow in trial E I, EII and E Ⅲ group was significantly higher than that in control group （P〈0.05 or P〈0.01）. The ingredients and formula of diets for E I, E II and E Ⅲ group were perfect diets for breeding beef cows.
