摘要: 选用利木赞杂交牛(均为阉公牛)30头,8~12月龄,栓系舍饲,采用随机完全区组设计(体重为区间)将试验牛分成6个营养模式组,进行300d的育肥,分析其日增重和饲料利用率,并对所有试验牛进行屠宰,测定其胴体质量和肉品品质,并对其经济效益进行分析。结果表明:低-高组饲料利用率和经济效益最好,高-高组增重速度和肉品品质最好。

Abstract: Thirty crossbred beef steers (Limousin + local yellow ),aged eight months to twelve months, were fed in the crib for 300 days and were divided into six nutrition pattern groups in randomized complete block design and differentiated weight by block. The average daily gains, the efficiency of feed utilization, carcass quality, meat quality and the profit of all output were tested and analyzed. The study shows that the low-high nutrition pattern group has the best efficiency in the feed used and the highest profits, and the high-high group has the best beef quality and the highest daily gain.
