【摘要】 8头4～5岁的役用秦川母牛按配对原则分为对照组和试验组。两组试牛的精料配方基本相同,但试验组牛饲粮用7.75%的鲁梅克斯K-1杂交酸模粉(以下简称鲁梅克斯)代替对照组中同等重量的小麦麸;对照组牛的粗料全部用干玉米秸,试验组牛用60%干玉米秸和40%的玉米秸+ 鲁梅克斯叶混合青贮料。正试期20d。结果表明:试验组牛的平均日增重为0.787kg,对照组为0.690kg,试验组较对照组牛日增重提高了14.06%;每增重1kg 活重试验组牛消耗精、粗料分别为2.54kg、5.25kg,对照组牛分别为2.90kg、5.50kg,试验组较对照组牛节约精料0.36kg,粗料0.25kg:试验组每头牛毛盈利为73.34元,对照组为59.40元,前者比后者提高经济效益23.47%。说明在役用母牛饲粮中,用鲁梅克斯粉代替精料中的小麦麸并用玉米秸+ 鲁梅克斯混合青贮料能获得良好的生产性能和经济效益。更多还原

【Abstract】 8 farm Qinchuan cows of 4-5 year-old were divided into control group and test group on pair principle. The formula of the concentrate fed in the two groups were alike, but in test group, 7.75% Polygonum Lumeikeshi K-1 powder (called Lumeikeshi for short in the following) were used to replace the same amount of wheat bran as used in control group. The roughage was totally dry corn stover in control group, while in test group it was composed of 60% dry corn stover and 40% silage made with corn stover and Lumeikeshi leaves. The test lasted for 20 days. The result showed that the average daily gain of the cows in test group was 0.787kg, while in control group it was 0.690kg and the daily gain in test group was increased by 14.06% over that in control group. 2.54kg concentrate and 5.25kg roughage were consumed for 1kg gain of live body weight in test group, while in control group 2.90kg concentrate and 5.50kg roughage were needed and 0.36kg concentrate and 0.25kg roughage were saved in test group compared with control group. In test group feeding each cow roughly 73.34 yuan was earned, while in control group 59.40 yuan was earned and the economic benefit of test group was increased by 23.47% over that of control group. It indicated that better performance and economic benefit can be reached by replacing wheat bran of the concentrate in farm cow diet with Lumeikeshi powder and using silage made with mixed corn stover and Lumeikeshi.更多还原
