Research Progress on Application of Cardamine hupingshanensis as Feed Additive for Laying Hens

Abstract

Functional feed additives are beneficial to improve the performance and egg quality of laying hens, and are increasingly used in intensive breeding processes, while long-term use of antibiotics as additives has led to problems such as drug residues in products and bacterial resistance. With the implementation of the anti-anti-biotic policy, the development of natural Chinese herbal medicines as feed additives for livestock and poultry has attracted widespread attention. The active ingredients in Cardamine hupingshanensis are selenoprotein, fla-vonoids, polysaccharides, amino acids, vitamins and other compounds, which have antioxidant, hypoglyce-mic, anti-inflammatory and analgesic, antibacterial, anticancer, improve immunity, improve intestinal flora and other functions. As a selenium-rich feed additive, Cardamine hupingshanensis can significantly improve the performance of laying hens. This paper summarized and analyzed the active ingredients and functions of Car-damine hupingshanensis, in aiming to provide a reference for the further research and large-scale application of Cardamine hupingshanensis as a feed additive for laying hens.
