摘 要:
选择不同日粮类型肉牛养殖户14户，参试生长母牛48头，参照肉牛营养需要和饲养标准，设计不同饲粮组合类型及日粮配方。随机分为5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、Ⅴ组和Ⅵ组（对照）按传统的“有啥喂啥”方法饲喂，同期进行饲养试验研究。结果表明，试验Ⅰ组、Ⅱ组和Ⅲ组平均头日增重效果均比Ⅳ组、Ⅴ组和Ⅵ组（对照）有明显提高（P〈0．05，P≤0．01），显示了肉牛标准化科学饲养的优势效益。试验Ⅰ组、Ⅱ组、Ⅲ组饲粮组成类型及日粮配方为较理想的肉牛繁殖母牛日粮优化配方。[著者文摘]

Abstract:
48 head growing cows were selected from 14 farm holdings which were fed different diets , and designed different diet ingredients and formulas according to nutrient requirements and feeding standard of beef cattle. 48 head growing cows were divided into 5 treatment groups and 1 control group at random. Trial Ⅰ , Ⅱ and Ⅲ group were fed with whole plant corn＋ammoniated wheat straw, but trial Ⅳ, Ⅴ and Ⅵ （control）group were fed what farm holdings had and selected traditional ways. The results indicated that the average daily gain per head of trial Ⅰ , Ⅱ and Ⅲ group were higher obviously than trial Ⅳ,Ⅴ and Ⅵ（control）group （P〈0.05, or P〈0.01）, and the advantages of science feeding with beef cattle standardizes were also revealed. The diet ingredient and formula of trial Ⅰ , Ⅱ and Ⅲ group were better as breeding cows diet.[著者文摘]
