中文摘要:

      [目的]试验旨在研究青贮和黄贮玉米秸秆对安格斯×湘西黄牛F1犊牛生长性能的影响，[方法]试验选自10头体重相近、生长状况良好的安格斯×湘西黄牛犊牛，随机分成2组，每组5个重复。[结果]结果显示，青贮组试验牛的采食量和末体重显著性高于黄贮组（P<0.05），青贮组试验牛的体尺发育优于黄贮组，但无统计学上差异（P>0.05）。青贮组的肉质品种粗蛋白、粗脂肪等显著性高于黄贮组（P<0.05）。[结论]以上试验结果说明，青贮玉米秸秆对安格斯×湘西黄牛犊牛的适口性更好，能促进体重的增长，但对犊牛的体尺发育较黄贮玉米秸秆无显著性的促进作用。

英文摘要:

      The purpose of this experiment was to study the effect of silage and yellow corn stover on the growth performance of Angus × xiangxi cattle F1 calves. 10 Angus × xiangxi cattle calves with similar body weight and good growth condition were randomly divided into 2 groups with 5 repetitions in each group. The results showed that the feed intake and final body weight of the experimental cattle in the silage group were significantly higher than those in the yellow group (P<0.05), and the body size development of the experimental cattle in the silage group was superior to that in the yellow group, but there was no statistical difference (P>0.05). The crude protein and crude fat of meat varieties in silage group were significantly higher than those in yellow silage group (P<0.05). The above experimental results showed that silage corn stover had better palatability for Angus × western hunan cattle calves and could promote the growth of body weight, but had no significant promoting effect on the body size development of calves compared with yellow corn stover.
