This research explored using mushroom stem waste as a beneficial feed additive for laying hens. The study found that adding mushroom stems to chicken feed improved their antioxidant levels and nutrient absorption without affecting egg production or quality. This discovery has several practical implications: • Reduces agricultural waste by repurposing mushroom stems that would otherwise be discarded • Provides a natural, cost-effective feed supplement for healthier chickens • Could lead to more nutritious eggs with higher antioxidant content • Offers environmental benefits through sustainable waste management • May help reduce feed costs for egg producers while improving chicken health
