中文摘要:

桑树作为传统中药材的来源，具有抗炎、杀菌等作用，这与桑树各部位中含有多糖、多酚、生物碱等生物活性成分有关。桑叶具有易采集及生物量大的优点而得到了最多关注。桑叶中多糖、多酚等生物活性物质具有降血糖、降血脂、增强免疫、增加抗氧化能力的作用，因此桑叶或其提取物应用于动物生产中对动物的健康有积极影响。桑叶粗蛋白含量高、氨基酸比例均衡，可替代一部分蛋白原料应用于畜牧生产中。但桑叶中抗营养因子含量较高，因此以发酵或青贮后饲喂动物为宜。综述了桑生物活性成分对动物糖脂代谢、抗氧化能力及免疫力的影响，并通过总结桑叶在畜禽及水产动物生产中的研究进展，阐述了桑叶在改善肉质、调节动物机体免疫及提高动物抗氧化能力等方面的作用。

英文摘要:

As a source of traditional Chinese medicine, mulberry has anti-inflammatory and antimicrobial effects, which is associated with its various bioactive components including polysaccharides, polyphenols and alkaloids in different parts. Mulberry leaf receives the most attention because it is easy to be harvested and has large biomass. Bioactive components in mulberry leaf such as polysaccharides and polyphenols, etc. have also been shown to be antidiabetic and antihyperlipidemic and can enhance immunity and antioxidant capacity. Therefore, mulberry leaf and its extract can be beneficial to animal health when applied to animal production. With high crude protein contents and balanced amino acid composition, mulberry leaf can be used in animal feeds to substitute parts of protein sources. However, there are large amounts of anti-nutritional factors in mulberry leaf. Therefore, mulberry leaf undergone fermentation and silaging may be more suitable for animal feeding. This paper reviews the effects of these bioactive components on glucolipid metabolism, antioxidant activity and immunity of animals, and elucidates the roles of mulberry leaves in improving meat quality,modulating immunity and enhancing antioxidant activity of animals through summarizing the research progresses of mulberry leaves in livestock and aquaculture production.
