The livestock industry requires high-quality products, as well as improved productivity. There have been many studies regarding the utilization of feed additives aiming to increase productivity, enhance immune functions and prevent infectious diseases in livestock. Biofunctional feed additives would be beneficial not only for animal health, but also for consumers. In the present study, we utilized root and byproduct (stem and leaf) powders of Angelica gigas Nakai (AGN, Korean Danggui) as feed additives and examined the deposition of biofunctional compounds, such as decursin and decursinol angelate, into egg white and yolk. RESULTS We optimized the detection system for decursin and decursinol angelate, and determined the amounts of decursin and decursinol angelate derived from AGN byproducts (stem and leaf) as well as root. In Experiment 1, laying hens were fed with the dried AGN root powder and the effective compounds were detected in egg white and yolk. Subsequently, in Experiment 2, we examined AGN byproducts as an alternative feeding supplement. Additionally, biochemical parameters were analyzed to evaluate changes in the health of the hens by feeding AGN root powder. The results obtained indicated that decursin and decursinol angelate were stably transferred into egg white and yolk by feeding AGN byproducts as well as root. Intriguingly, plasma cholesterol levels were significantly decreased in a dose-dependent manner, and those of interleukin-1?, as an immune-related biomarker, were considerably increased in the treated hens. CONCLUSION These results indicated that AGN root and byproducts (stem and leaf) could be utilized for the production of value-added eggs and improving the health of hens in the poultry industry. ? 2018 Society of Chemical Industry
