摘要
[目的]本试验主要探讨揉搓机处理玉米秸杆饲喂三元杂交肉牛的效果。[方法]试验分铡草机处理玉米秸杆、铡草机处理青贮玉米秸杆、揉搓机处理打捆袋装玉米秸杆3个组进行对比分析。[结果]采用揉搓机处理玉米秸杆打捆袋装青贮饲料饲喂肉牛增重速度最快,日增重1.18kg,比铡草机处理青贮玉米秸杆的1.03kg提高14.56%(P<0.05)、比铡草机处理玉米秸杆的0.88kg提高34.09%(P<0.01)。[结论]经揉搓机处理青贮玉米秸杆饲喂肉牛具有营养价值好,适口性强,利用率高,增重效果和经济效益高的特点,适宜在生产中大力推广。
[Objective]The objective is to discuss the feeding effect of corn straw dealt with kneading machine on three hybrid beef cattle. [Method]Comparative analysis was carried on three groups which were divided according different processing methods by corn straw dealt with hay cutter, silage corn straw pro cessed with hay cutter and corn straw bundling in bags dealt with kneading machine. [Result]The weight gain feeding corn straw silage bundling in bags dealt with kneading machine was the best than the other two processing methods. The daily weight gain was 1.18 kg,which increased 14.45% and 34.09% than si lage corn straw and corn straw processed by hay cutter. [Conclusion]The silage corn straw processed by kneading machine had the characters of good nutritional value and palatability, high utilization, weight gain effect and economic efficiency, which was suitable for strong extension in practice.
