Danmeimei is a functional feed additive designed for laying hens, especially during the mid-to-late laying period or for flocks with insufficient yolk color and declining eggshell quality. Formulated with carotenoids, humic acid–complexed trace elements, and pine needle extract, it supports efficient pigment deposition in the yolk for a more uniform, glossy orange-red color, while its antioxidant components help slow yolk lipid oxidation and maintain egg freshness. Through the synergistic action of highly available trace elements and natural bioactive substances, Danmeimei also supports calcium metabolism, eggshell formation, shell gland function, and oviduct health, helping improve shell strength, reduce cracked and soft-shelled eggs, and maintain stable laying performance. Overall, it provides an integrated solution for improving yolk color, eggshell quality, freshness, and the market value of eggs.
