Summary
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
Background
Agaricus bisporus is a commonly cultivated mushroom with stem residue accounting for 10-13% of total mushroom weight. The stem has similar nutritional composition as the cap but is often treated as waste during processing. Laying hens produce eggs daily and have vigorous energy metabolism, making them susceptible to oxidative stress as they age. Natural additives are increasingly sought to improve antioxidant capacity and immunity in laying hens.
Objective
To investigate the effects of Agaricus bisporus stem residue (ABSR) on laying hen performance, nutrient digestibility, antioxidant activity, and egg storage quality to determine appropriate ABSR dosage and provide scientific basis for effective utilization of this mushroom byproduct.
Results
ABSR had no significant effect on laying performance. Crude protein and total energy digestibility were significantly higher in experimental treatments compared to control. No significant differences in egg storage quality were found. Superoxide dismutase and glutathione peroxidase activity in serum and yolk were significantly higher in experimental treatments, while malonaldehyde content was lower. Optimal ABSR supplementation level was calculated at approximately 5%.
Conclusion
ABSR can improve protein and energy utilization, increase antioxidant substances in serum and yolk, and enhance antioxidant capacity of laying hens without negatively affecting laying performance or egg storage quality. ABSR shows potential as a natural health promoter for laying hens at approximately 5% dietary inclusion.
