摘　　要：构树是优质的饲料原料,粗蛋白、氨基酸、粗脂肪、微量元素等含量丰富,且富含黄酮类、葡萄糖苷、生物碱类等多种生物活性成分,具有提高动物生产性能、增强机体抗氧化能力、改善畜产品品质等功效。发酵和青贮能将结构复杂的构树蛋白质分解成易于消化吸收的短肽和氨基酸,降低粗纤维、木质素、单宁等抗营养因子含量,改善构树饲用价值。该文就构树饲料中的营养和生物活性成分、主要抗营养因子、发酵和青贮对构树饲料营养组成和含量的影响及其在动物养殖生产上的应用进行了综述。Broussonetia papyrifera is an excellent source of feed material.It has an abundance of crude protein,amino acid,crude fat and trace elements,as well as bioactive components such as flavonoids,glucoside,and alkaloids,which can improve the reproductive performance,organism anti-oxidization capabilities in livestock and the overall quality of animal by-products.Fermentation and silage can break down the complex protein of Broussonetia papyrifera into small peptide and amino acid,which are easier to absorb and can decrease the content of anti-nutrition factors such as crude fibre,lignin and tannin,thus improve the feed value of Broussonetia papyrifera.This article reviewed the effects of nutrient and biologically active ingredients,main anti-nutritional factors,fermentation and silage on the nutrient composition and content of Broussonetia papyrifera feed and its application in animal producation.
