Popis: This experiment was performed to evaluate the effect of the in ovo injection of carbohydrates, antioxidants, and their combination into the stored incubating eggs. To conduct this research, 600 hatching eggs were selected for amniotic injection (on 17.5th embryonic day) from the laying hens of Cobb 500 strain after 14 days of storage, and after hatching, they were distributed for a rearing period in 5 treatments and 5 replicates in a completely randomised design(24 eggs per replicate). Experimental treatments include: (1) Negative control (NC) (without injection), (2) Positive control (PC) (injection of 0.5 ml normal saline solution), (3) Injection of 0.5 ml carbohydrates solution (CS), (4) Injection of 0.5 ml antioxidant solution (AS) and (5) Injection of 0.5 ml (CS) + (AS). The hatching percentage, chicken weight, the number of red cells, lymphocytes and tissue glycogen content in CS + AS treatment increased significantly compared to the control (p
