摘要:

随着我国养殖业“减抗、禁抗、产品无抗”战略的实施,使用植物提取物作为饲料添加剂成为重要的研究方向。甘草多糖是一种从甘草中提取的植物多糖,提取方法包括溶剂萃取法、超声辅助萃取法、微波辅助萃取法等。甘草多糖作为天然生物大分子由阿拉伯糖、葡萄糖、半乳糖、鼠李糖、甘露糖、木糖等单糖组成,具有抗氧化、抗炎、免疫调节、抗肿瘤等多种生物学活性,在保障动物健康方面具有显著的作用。在动物饲粮中添加甘草多糖可提高其体重增长率、饲料利用率和肉品质,同时减少肠道疾病和应激对动物产生的负面影响。由于其抗炎和抗氧化作用,甘草多糖可以有效减轻动物因疾病和应激引起的炎症和损伤。本文综述了甘草多糖提取方法、生物学活性和作用机制,并探讨了其在动物生产中的应用,以期为甘草多糖在养殖中的应用提供科学依据。

Abstract:

With the implementation of the strategy of "reducing antimicrobials, banning antimicrobials, and making products antimicrobial-free" in China's aquaculture industry, the use of plant extracts as feed additives has become an important research direction. Glycyrrhiza polysaccharide is a kind of plant polysaccharide extracted from licorice, and the extraction methods include solvent extraction, ultrasound-assisted extraction, and microwave-assisted extraction, etc. As natural biomolecules, Glycyrrhiza polysaccharides consist of monosaccharides such as arabinose, glucose, galactose, rhamnose, mannose, xylose, etc., which have a variety of biological activities such as antioxidant, anti-inflammatory, immunomodulatory, anti-tumor and so on. It has a significant role in protecting the health of animals. The addition of Glycyrrhiza polysaccharide to animal diets can improve body weight growth rate, feed utilization, and meat quality, in addition reducing the negative effects on animals caused by intestinal diseases and stress. Due to its anti-inflammatory and antioxidant effects, Glycyrrhiza polysaccharide effectively reduces inflammation and damage induced by disease and stress in animals. In this paper, the extraction methods, biological activities, and mechanisms of action of Glycyrrhiza polysaccharides were reviewed, their applications in animal production were also discussed, in order to provide a scientific basis for the application of Glycyrrhiza polysaccharides in animal breeding.

Key words: Glycyrrhiza polysaccharide, biological activity, mechanism, animal production
