木薯作为能量饲料在猪生产中的应用

Application of cassava as energy feed in pig production

我国常规饲料(玉米、豆粕等)资源紧缺,挖掘非常规饲料迫在眉睫。木薯具有高淀粉含量、单产高、对种植环境要求低等特点,是谷物饲料的最佳替代品。然而,木薯含有单宁、氢氰酸等抗营养因子,需加工处理后才能够作为饲料能量来源。文章就木薯的营养特性、生产工艺和在猪养殖中的应用情况进行总结,以期为后续的研究提供一定参考。

The resources of conventional feed(corn,soybean meal,etc.)are scarce in our country,so it is urgent to explore unconventional feed.Cassava has the characteristics of high starch content,high yield per unit and low requirements for the planting environment,and is the best substitute for grain feed.However,cassava contains anti-nutrient factors such as tannin and hydrocyanic acid,which need to be processed before it can be used as a source of feed energy.In this paper,the nutritional characteristics,production technology and application of cassava in pig breeding were summarized in order to provide some reference for the subsequent research.
