蔬菜茎叶混合青贮技术及其应用研究进展

蔬菜茎叶青绿多汁,适口性好,含有丰富的粗蛋白、粗脂肪和粗纤维,是牲畜的优质饲料.然而,除了小部分作为青绿饲料直接饲喂动物外,大部分蔬菜茎叶下脚料被遗弃或抛弃,这不仅造成资源浪费,而且造成环境污染.通过青贮等方式将蔬菜茎叶加工成动物饲料,既可以提高其利用价值,又可以取得良好的社会效益.对蔬菜茎叶混合青贮技术、影响青贮效果的因素及其在养殖业中的应用进行了综述.

Research Progress on Technique and Application of Mixed Silage of Vegetable Stems and Leaves

The vegetable stems and leaves are succulency, palatable and contain abundant crude protein, crude fat and crude fiber. They are high quality feed for livestock. However, except for a small part is used as green feed for animal, most of the vegetable leaf waste is deserted or abandoned. This is not only a waste of resources, but also causes environmental pollution. Silage can raise the use value of vegetables stems and leaves as the animal feed and reduce the environment pollution of the vegetable leaf waste. The technology, influence factors and applica- tion of mixed silage of vegetables stems and leaves are reviewed.
