甘蔗尾叶青贮及其饲喂价值的研究现状

Research Status of Sugarcane Tops Silage and Its Feeding Value

甘蔗尾叶是甘蔗收获后残留的甘蔗顶部2至3个嫩节及其附带的整个叶片,属中等品质粗饲料,但由于缺乏深入研究,我国每年有近千万吨甘蔗尾被浪费。将甘蔗尾叶饲料化不仅可以解决冬季饲料资源短缺、减少环境污染等问题,同时还能缓解人畜争粮的矛盾。本文主要对鲜甘蔗尾叶及其青贮饲料营养价值、在反刍动物生产中的利用进行论述。

The sugarcane tops is a medium-quality roughage that is the last 2 to 3 tender sections with their leaves. Due to the lack of in-depth research, the annual production of nearly 10 million tons of sugar cane tops are not well utilized, which results in waste of feed resources. Feeding the sugarcane tops not only can solve the shortage of winter feed resources and reduce environmental pollution, but also can alleviate the contradiction of diet-consuming between human and animal competition.This paper mainly reviews the nutritional value profile of fresh sugarcane tops and their silage, and the utilization of sugarcane tops silage in ruminant production.
