青贮玉米在世界许多国家早已大量种植,被公认是一种优质饲草。玉米作青贮用,具有产量高,易于机械化栽培,连作危害较小等优点。近几年来,我国的青贮玉米有了较大的发展,为缓解畜、草、粮矛盾,促进畜牧业发展起了重要作用。青贮玉米的优点以粮食为主饲料发展畜牧业,不仅受粮食供给总量的限制,而且很不经济,植物的茎、秆、叶等部分不能很好利用,青贮玉米则全株的干物质都用作了饲料,经济高效。青贮玉米单位面积产量高,营养丰富,适口性好,还具有较高的可消化率,为家畜的代谢提供较多能量。青贮玉米既可作青贮饲料,直接喂养反刍动物,还可晒制干草备用,非常灵活。充分用青贮玉米作饲料,合理搭配精料,可降低饲料成本,提高经济效益。青饲玉米属多汁饲料,可以增加食欲,提高适口性,供给家畜多种维生素,增强抗病力并增加奶牛产奶量。
Silage corn has long been planted in many countries around the world and is widely recognized as a premium forage. Corn for silage, with high yield, easy mechanized cultivation, continuous cropping less harmful. In recent years, China’s silage corn has made great progress, which has played an important role in alleviating the contradictions of livestock, grass and grain and promoting the development of animal husbandry. The advantages of silage corn The development of livestock husbandry based on grain-based feed is not only limited by the total amount of food supply, but also uneconomical. The stems, stalks, leaves and other parts of plants can not be utilized well. The silage corn is the whole plant’s dry matter Used as a feed, cost-effective. Silage corn has high yield per unit area, rich nutrition, good palatability and high digestibility, which provides more energy for livestock metabolism. Silage maize can be used as silage, direct feeding of ruminants, but also drying hay spare, very flexible. Full use of silage corn for feed, with a reasonable material, can reduce feed costs, improve economic efficiency. Green fodder corn is a juicy feed, can increase appetite, improve palatability, supply of livestock vitamins, enhance disease resistance and increase milk production.
