How to deal with the corn stalk? Most people use 青贮打包机 to wrap it into bundles so as to store it for a long time? What’s the current situation and value of corn silage?
玉米青贮的价值
玉米青贮是草饲牲畜养殖中不可或缺的基础饲料之一。尤其近年来，随着中国加快农业地区的工业化，玉米青贮饲料的发展变得日益重要。使用青贮打包机后，玉米秆会被加工变软，保持青绿多汁的状态长时间。加工后的青贮具有清晰的芳香气味，大大提高了秸秆的适口性。玉米青贮饲料能最大程度地保存营养，通常只损失3%至10%的营养成分。粗蛋白和胡萝卜素的损失较少。而干燥玉米秆饲料则可能损失30%至50%的营养，几乎所有的维生素都被破坏。
青贮玉米饲料与风干玉米秸秆饲料的主要区别
与风干玉米秸秆饲料相比，玉米青贮的粗蛋白质含量大约高出1倍，粗脂肪高出约4倍，粗纤维则低约7.5%。经过青贮玉米秆的加工，饲料中的粗蛋白质含量可以提高3.4%至16.4%。粗纤维含量显著降低，有机物的消化率提高4.8%至15.4%。重要的是，消化能增加0.23-0.62兆卡，代谢能增加0.19-0.56兆卡。
玉米青贮的栽培与利用
At present, the developed areas of animal husbandry in the world to feed dairy cows, beef cattle, dairy sheep and mutton sheep are the United States, Europe, Canada and Japan. Silage corn is planted in large quantities with wide application, which greatly promotes the development of herbivorous livestock. For example, the United States planted silage corn 2.52 * 107hm2. From 1988 to 1997, they planted 2 * 106hm2, and most of them was used to make silage corn feed, accounting for about 8% of the planted area. The use of silage corn forage production varies greatly due to the development of herbivorous livestock in different regions. The proportion of silage corn forage in California and Europe accounts for 56% and 47% . France grows silage corn 15 * 106hm2 annually. Italy grows 3.5 * 105hm2, and Germany grows 9.3 * 105hm2, which accounts for more than 80% of the corn planting area. All those countries use 青贮打包机 to process the corn silage and other grasses.
