桑叶的营养价值、生物学功能及其在畜禽生产中的应用OA

In recent years,conventional feed resources in China have been unable to meet the demands of the rapidly developing livestock industry.The utilization of novel feed resources and the development of unconventional feed alternatives have become urgent issues for practitioners in the sector.China boasts high mulberry yields and extensive cultivation areas.Mulberry leaves are rich in nutritional value,containing crude protein,crude fat,minerals,amino acids,and other nutrients,as well as substantial amounts of bioac-tive compounds such as flavonoids,alkaloids,phenols,and polysaccharides.As a common traditional Chi-nese medicinal material,mulberry leaves possess various biological functions,including antioxidant,anti-inflammatory,and antibacterial properties,indicating significant potential for development and utilization.This article reviews the nutritional value,active components,biological functions of mulberry leaves,and their applications in livestock and poultry production,aiming to provide references for the use of mulberry leaves as an unconventional feed resource and for subsequent research.
