摘要
利用氨-碱-盐化和微生物技术复合处理作物秸秆,再配合工业副产品、精料及矿物质、维生素添加剂等制成颗粒饲料,饲喂成年滩羊,观察育肥效果。试验结果表明:试验组(复合处理秸秆)与对照组(未处理秸秆)相比,日增重提高25.06%,饲料报酬提高25.23%,屠宰率提高5.11%,净肉率提高7.71%,试验期内平均每只育肥羊多获利润13.13元。
Maize stalks, treated by an integrated processing methods of ammonia, alkaline, brine, and microbe, were mixed with industrial byproduct, concentrate, minerals and vitamin additive to process into the pellets of the total mixed ration. The pellets were fed to Tan sheep to investigate the fattening performance. The results indicated that the daily body weight gain, feed efficiency, dressing percentage and meat percentage of the experimental group were increased by 30.01%, 25.96%, 5.11% and 7.7%, respectively compared with the control group. Mean while, the average net income per head of experimental group is 13.13 Yuan more than that of control group during whole experimental period.
