秸秆资源开发技术及在舍饲中的作用研究

准格尔旗秸秆资源丰富 ,加工利用潜力巨大 ,对其科学利用可缓解草畜矛盾 ,促进生态环境的恢复。玉米秸秆除传统的青贮外 ,还可加工成草块、草捆 ,这样便于贮存和长途运输。加工后的饲料营养损耗少 ,适口性好 ,采食利用率高 ,可降低饲养成本。奶牛饲喂玉米秸秆草块比饲喂玉米秸秆青贮料日增重提高 2 4%～ 3 9%,饲喂玉米秸秆青贮料比饲喂玉米秸秆干草料日增重提高 2 5 %～ 3 0 %

Development Technique of Crop Straws and Study of Its Effect in Pen-Feeding

There are rich crop straw resource with great potential for processing and utilization, and scientific use of the resource will promote recovery of ecological environment and alleviation of conflict between grass and livestock developments. Corn straw can be both ensilaged and processed into blocks and bundles that is easy for storage and long distance transportation. The processed fodder is little in nutrition loss, agreeable to livestock taste and with high using rate to decrease feeding cost. Milk cow feeding with processed corn straw block can increase daily weight increment by 24% to 39% higher than that feeding with silage corn straw that in turn 25 % to 30% higher than that feeding with dry corn straw grass fodder.
