摘要
本试验以自由采食酒糟的犏牛为对照,以自由采食酒糟并日补1公斤精料的犏牛作为试验牛。在酒糟中加补一定量的配合精料,可补充酒糟中碳水化合物、钙、磷的不足、满足肉牛的增重需要。在92天试验期内,试验组较对照组日增重提高0.24公斤;肥育期缩短23天;每增重1公斤,少消耗干物质1.47公斤、代谢能1.45兆卡、可消化粗蛋白质192、17克;牛均多获纯利48.08元,提高经济效益40.88％。
This experiment compared the beef eating freely wine lees with the experimental beef raised with eating freely wine lees and 1 kg concentrated feed a day. The results showed that the wine lees with some concentrated feed can supplement the insufficiency of carbon, calcium, phosphorus in wine lees, meet the needs of beef in increasing weight, and increase the utilization ratio of wine lees futher, During 92 experimental days, the experimental group increases the weight of 0.24kg a day,and the fatten period shortens 23 days as compared with the compared group, when beef increases 1 kg, it consumes 1.47kg dry matter, 1.45million calorie ME, and 192.17g digestive crude protein less than the compared group. The average pure profit increases 48.08 yuan, and the benifit 40.88%.
