# Research progress on biological functions of astragalus stems and leaves and their application in cattle production: a review

## TL;DR

Astragalus stems and leaves are a nutritious and cost-effective feed additive that can improve cattle health and production.

## Contribution

This review compiles the biological functions and applications of Astragalus stems and leaves in cattle production.

## Key findings

- Astragalus stems and leaves contain bioactive compounds like polysaccharides and flavonoids with antioxidant and anti-inflammatory properties.
- They offer a low-cost alternative feedstuff that can enhance cattle health and reduce feeding costs.
- ASL can support animal nutrition regulation and forage development in cattle production.

## Abstract

Astragalus stems and leaves (ASL) represent a promising feed additive to improve cattle health and production efficiency. They are rich in nutrients and active substances, such as polysaccharides, flavonoids, alkaloids, exhibit antioxidant, antibacterial, anti-inflammatory, and other biological functions. With the advantages of high yield and low price, ASL are excellent potential feedstuff resources that could alleviate the shortage of conventional feed and reduce feeding costs. This review highlights the botanical characteristics, phytochemical components, nutritional and pharmacological effects of ASL, as well as their applications in cattle production, which could be beneficial for animal nutrition regulation and forage development.
