The biological functions of phytogenic polysaccharides as feed additives

Phytogenic polysaccharides are a class of active materials with various biological functions. They have been widely applied in livestock breeding as functional feed additives, which promote growth, strengthen immunity, improve bowel health and product quality. This paper summarized the research progress on the biological functions and working mechanisms of phytogenic polysaccharides, and explained the application effects as well as existing problems in livestock farming breeding, to provide a good reference for further exploration in this research area.
