Abstract

Natural plant herbs have many active compounds to prevent poultry diseases and improve poultry products. However, most herbs are supplied for human medicine. Thus, for economic and sustainable development purposes, the dregs of Cardamine hupingshanensis (DCH) were developed as a feed additive to improve the egg quality of laying hens in this work. Results showed that the contents of selenium in hen serum and eggs were increased under DCH feeding. Subsequently, DCH also promotes the antioxidant capacity and immunity of laying hens through the increase of superoxide dismutase (SOD), catalase (CAT), and immunoglobulin G (IgG) by ELISA detection. Finally, production performance and egg quality were further graded by monitoring the product condition and scoring the indexes of egg quality, which also displayed that DCH as a feed additive significantly improved the egg quality by enhancing yolk color, eggshell thickness, and egg shape index.

Keywords: dregs of Cardamine hupingshanensis; egg equality; feed additive; laying hens; production performance.

Effects of DCH on antioxidant capacity and immunity. (A) Workflow of the experiment. The laying hens were fed for 30 days and collected eggs on days 0, 10, 20, and 30 for production performance and eggs quality evaluation. Serum samples and organ samples were collected on the day 30 for growth performance evaluation.

The DCH was added into diet as an additive to feed laying hens, which increased the content of serum selenium, improved the levels of SOD and CAT, accelerated the elimination of free radicals, improved the antioxidant capacity and immunity, and then enhanced the production performance and egg quality of laying hens.
