摘　　要：作为一种非常规蛋白质饲料,桑叶具有较高的营养和经济价值。桑叶适口性好,富含蛋白质、氨基酸、黄酮、生物碱、多酚、多糖等生物活性物质。近年来,随着桑资源的开发利用,桑叶及其提取物在畜牧领域应用的研究越来越深入。作为畜禽生产中的优质饲料来源,桑叶以干燥、青贮、发酵、活性物质提取等加工方式为主。不同的加工方式对桑叶中营养成分的组成和含量产生不同的影响。在畜禽饲粮中添加桑叶或其提取物,可以提高畜禽的免疫力、成活率、生产性能和抗氧化能力,改善肠道微生态,调节代谢等,从而提高畜禽产品品质,但其在不同动物、同一物种不同发育阶段的应用不尽相同。作者综述了桑叶的饲用价值、加工方式及其在畜禽生产中的应用,旨在为桑叶的合理开发利用提供依据,推动畜牧业高质量发展。As an unconventional protein feed,mulberry leaves have high nutritional and economic value.Mulberry leaves are palatable and rich in protein,amino acids,flavonoids,alkaloids,polyphenols,polysaccharides and other bioactive substances.In recent years,with the development and utilization of mulberry resources,the research on the application of mulberry leaves and its extracts in the field of animal husbandry has become more and more in-depth.As a high-quality feed source in livestock and poultry production,mulberry leaves are mainly processed by drying,silage,fermentation,extraction of active substances,etc.Different processing methods have different effects on the composition and content of nutrients in mulberry leaves.Adding mulberry leaf or its extract to the diet of livestock and poultry can improve the immunity,survival rate,production performance and antioxidant capacity of young livestock and poultry,improve intestinal microecology,regulate metabolism,and improve the quality of livestock and poultry products.The application of mulberry leaves varies among different animals,and different developmental stages of the same animal species.The authors summarized the feeding value,processing methods and application of mulberry leaves in livestock and poultry production,in order to provided the basis for the rational development and utilization of mulberry leaves and was conducive to promoting the high-quality development of animal husbandry.
