The possibilities of using the vegetative mycelium of xylotrophic fungi of the varnished tinder fungus (Curt.:Fr.) P. Karst. and tinder funnel of sulfur yellow (Bull.) Murrill as food additives for poultry of the parent flock. These types of mushrooms are known as promising biotechnology producers of compounds of sterol and carbohydrate nature, carotenoids, vitamins and other substances with high biological activity. In the process of growing the mycelium was enriched with trace elements germanium, which can partially stop oxygen starvation in tissues. Powdered feed additives were fed with the main diet and allowed to increase the total blood protein of poultry against the background of fraction growth by 5-7%, and the hemoglobin content - by 7-9%. A positive effect on the immune parameters of the parent flock blood and the antioxidant status of their body were established, and a decrease in the markers of oxidative processes was shown. Feed additives allowed to increase the safety of the parent poultry flock, improve incubation rates of eggs, increase the rates of chickens by 5-6% relative to the control.
