Abstract


The nutrient profile of poultry feed is a critical factor influencing both the quality and functional attributes of chicken eggs. This study evaluated the impact of incorporating Cordyceps militaris by-product into the diets of laying hens on their productive performance and egg quality. A completely randomized design was used, involving five dietary treatments with ascending levels of Cordyceps militaris by-product powder over an 8-week feeding period. Key productivity metrics were monitored daily, while egg quality parameters were analysed weekly. Results demonstrated that dietary supplementation with Cordyceps militaris by-product significantly enhanced reproductive performance, including egg count, laying percentage, egg mass, and feed conversion ratio. Additionally, yolk coloration improved notably in treated groups, showing a clear dose-response effect. In conclusion, enriching laying hen diets with Cordyceps militaris by-product boosts egg productivity and yolk pigmentation. These findings support the potential of this natural supplement in poultry nutrition for the production of high-quality, health-promoting eggs.
