摘　　要： 山蚂蝗属(Desmodium)植物适应性强,生长快,草产量高,粗蛋白含量高,氨基酸含量丰富,钙磷比适宜,且富含多种微量元素;单宁是其主要抗营养因子,单宁可与蛋白质生成络合物,降低蛋白质利用率,影响干物质、纤维等养分消化率,降低动物采食量,但适量的单宁可降低蛋白质在瘤胃内的降解率,缓解动物臌胀病,提高动物生产性能和抗病能力。将山蚂蝗属植物作为蛋白补充料与粗饲料配合饲喂动物,可提高粗饲料利用价值,降低生产成本。因此,山蚂蝗属植物是我国热带亚热带地区极具潜力的植物性蛋白饲料资源。 Desmodium genus are adaptable,fast-growing and high productive plants,they have high content of crude proteins and amino acids,suitable ratio of calcium and phosphorus,and rich in several kinds of microelements.In Desmodium,tannin is a main anti-nutrition factor,because it can produce complex compound through binding with protein,which results in the reduction of utility of protein and animal intake,and effects digestibility of many nutrients,like dry matter,fiber,etc.On the other hand,appropriate amount of tannin can also reduce the degradation of protein in rumen,release the tympanites of animal and improve the productive performance and disease resistance.Therefore,Desmodium varieties can promote the nutritional value of crude forage and cut down the cost of production when they are used as supplementary of crude forage to feed animal,they are excellent protein resource of feed plant which are of great potential in subtropical and tropical areas of China.
