摘　　要：芋头是粮蔬兼用型作物。我国年产鲜芋头约180万t,在其种植和加工产业中伴生的可饲用资源估测约有81万t。芋头和茎叶中含有的草酸钙针晶体和单宁具有刺激性,宜青贮、发酵或熟制后饲用,发酵或熟制后在日粮中的用量可达20%而不影响动物生产性能。芋头种植需肥量大,可消纳猪场的沼液。笔者介绍了我国芋头主产地分布和饲用资源蕴藏情况,可为芋头饲用资源的产业化利用提供参考。Taro (Colocasia esculenta (L.)Schott)both are grain and vegetable.The annual output of fresh taro in China is about 1.8 million tons,and feed resources in cultivation and processing is about 810 thousand tons.The calcium oxalate crystal and tannin contained are irritant in taro and stem and leaf.After silaged,fermented or cooked,the taro feed dosage in the diet can reach 20% without affecting the animal production performance.Taro cultivation needs large amount of fertilizer and can be used to remove biogas slurry from pig farms.This paper summarizes the distribution of main taro producing areas and the reserves of forage resources in China,which can be used for reference in the industrialization of taro feed resources.
