| 摘 要： | 将纯种草原红牛和含1/2利木赞血缘的改良草原红牛各16头在相同营养水平和饲养条件下进行10个月的集中舍饲育肥，研究了2组牛生长速度、产肉率及眼肌面积、大理石花纹和嫩度等肉质水平。结果显示, 改良牛的体高、体长、胸围、体质量、增重、屠宰率和净肉率等极显著或显著地高于草原红牛（P<0.01或P<0.05），改良牛的眼肌面积比草原红牛增8.39%，大理石花纹等级和嫩度剪切力值也略大于草原红牛，但差异均不显著(P>0.05)。试验结果表明，利木赞牛对草原红牛的肉用性能改良效果显著，且对草原红牛的肉质没有明显影响,草原红牛保持了其原有肉质好的品种特性。

| Abstract: | Sixteen China Red Steppes and sixteen China Red Steppes crossbred with Limousin were fed and fattened under same nutrition and feeding conditions for ten months.It was studied that growth velocity,meat performance,and the meat quality including tenderness,area of loin eye muscle,and marbling of these cattles after they had been fattened and abataged.The results showed that the body height,stem length,across chest,marketing weight,body weight gain,dressing percentages,and meat percentages of the crossbreds were higher significantly than those of China Red Steppes(P<0.01 or P<0.05).The area of loin eye muscle of the crossbreds was improved 8.39% than that of China Red Steppes.The enderness and marbling of the crossbreds were higher slightly than those of China Red Steppes.But there were no significant different among those items(P>0.05).This experiment showed that the effect of improve of meat performance of China Red Steppe by crossbreeding with Limousin was very significant.The crossbreeding did not affect meat quality of China Red Steppe.The China Red Steppe had still retained its specific property of preeminent meat quality. |
