摘要
本文对氨化麦秸喂牛的效果进行了研究。试验牛选用西门塔尔×本地黄牛杂交一代阉牛12头,随机分为试验、对照两组,每组6头。试验结果表明:平均日采食量试验,对照组分别为5.22、4.46公斤,平均日增重分别为278.29、68.90克,组间差异均极显著(P<0.01);试验组每增重1公斤饲料消耗量和成本分别比对照组降低257.68％、220.35％。说明用氨化麦秸喂牛效果显著优于普通麦秸。
The effect of using ammoniated wheat straw to feed cattles is introduced in this paper. 12 simmental one's region yellow F1 stress in this experiment were divided into experimental and contral groups, 6 per group. The results have shown: The average daily intake of experimental and contral groups was 5.22 and 4.46 kg respectively; The average daily gain was 278.29 and 68.90g respectively; The feed conversion ratio and the feed cost/kg gains of experimental group were reduced by 257.68 and 220.35％ as compared with the contral group respectively. There were magnificent differences between 2 groups in terms of daily intake,daily gains (P<0.01 ). It was shown that the effect of using ammoniated wheat straw to feed cattles was better than that of ordinary wheat straw.
