薯类加工副产物饲料化应用研究进展

Research Progress on Feed Application of Tuber Processing by-products

薯类作物是我国重要的粮食和经济作物,在保障国家粮食安全、提供工业原料、促进社会经济发展等方面发挥着重要作用。然而,在其生产加工过程中产生的大量副产物被废弃,造成严重的资源浪费和环境污染。随着我国集约化畜禽养殖业的快速发展,畜禽饲料原料的需求量迅速增加,人畜争粮问题逐渐凸显。利用薯类加工副产物替代动物饲料中的谷物原料,既可实现其资源化利用,又可减少养殖动物对谷物原料的大量需求,是缓解目前人畜争粮问题的可行途径。文章从我国薯类资源的现状、营养与抗营养成分、薯类副产物的加工及其在畜禽养殖中的应用等方面进行综述,为促进其在畜禽养殖中的应用提供参考与思路。

Tuber crop is an important food and economic crop in our country,which plays impor⁃tant roles in ensuring national food security,pro⁃viding industrial raw materials,and promoting so⁃cial and economic development.However,a large number of by-products are produced in its pro⁃cess,resulting in serious resource waste and environmental pollution.With the rapid development of intensive livestock and poultry production in China,the demand for feed materials rapidly increases,and the problem of the food competition between people and livestock has become more and more prominent.Using tuber by-products to replace grain raw mate⁃rials in animal feed can not only realize the resource utilization of these by-products,but also reduce the large demand for grain raw materials,which is an ideal solution to improve the current issue of humanlivestock competition for grain.This article reviews the current situation of tuber resources,nutrition and anti-nutrient components,processing of tuber by-products,and their application in livestock and poultry production in China,and provides reference and strategy for promoting their application in animal pro⁃duction.
