| 摘 要： | 在相同环境条件下，试验在3种苜蓿草块添加量下对不同品种肉用牛进行5期的育肥效果研究。通过测定不同品种的体重、日增重及粗饲料采食量，来比较不同品种肉牛增重效果。试验结果表明，在精粗比下降的情况下，添加苜蓿草块能起到提高日增重的效应，与不添加相比，荷斯坦组差异极显著（P<0.01），新褐杂组前后差异显著（P<0.05）,安杂组差异不显著（P>0.05）。在本试验营养水平与体重下，新褐杂组、荷斯坦组、安杂组各组苜蓿草块适宜的添加量分别为1.2、1.2、0.5 kg。结合农区养牛现状及生产力水平在低精粗比的情况下，肉牛应该首先考虑使用本地优良品种。

| Abstract: | In the same environmental conditions,the experiments in three alfalfa grass block recruitment conducts five phase of fattening effect research to the different variety beef cattle.Through the determination of different variety beef cattle's body weight,average daily gain and roughage intake,compare effects of different variety beef cattle weight gain.The results show that the increase alfalfa grass block can have the enhancement to average daily gain effect in degree of feed compared to the drop situation,with do not add compared Holstein group was significantly difference(P<0.01),and Xinjiang brown cattle group was difference remarkable(P<0.05),and Angus group there was no significant difference(P>0.05).The alfalfa grass block's increase in this experiment nutritional level and the body weight,the Xinjiang brown cattle,the Holstein,the Angus each group of being suitable recruitment respectively is 1.2,1.2,0.5 kg.District fishery area raising cattle present situation and productive forces level in low level of feed compared to the situation,the beef cattle should first consider the use of local fine varieties. |
