| Summary: | The addition of manganese to the feed was applied to support the immune system of chickens and improve physiological characteristics and energy levels during and after the period of feed restriction of broiler (Ross 308). Using 180 chicks, divided into five groups with 45 chicks in each group and distributed into three replicates, each replicate contains 15 chicks. The groups were 0 manganese (Mn) + (ad libitum diets), 0 Mn + Feed restriction 8 h/day, 75, 100, and 125 mg Mn/ kg feed+ feed restriction 8 h/day for groups G1, G2, G3, G4, and G5 respectively, and were subjected to feed restriction (8 hours/day) for 8-14 days of the experiment. The results were: significantly (P≤0.05) superior to group G4 in the relative weight of the Bursa of Fabricius at the age of 21 days and for the groups G3 and G5 in the antibodies of Newcastle and IBD at the age of 21 and 35 days and group G3 in the relative weight of the thymus gland at the age of 35 days. In liver glycogen superiority of groups G1, G4, and G5 group increase in the muscle glycogen and red blood cells, the groups G1, G4 and G5 were significantly superior at the age of 21 days, and the group of G4 was superior at the age of 35 days compared with the rest of the groups , also significant increase in the ratio of H/L, triglycerides, uric acid, AST and ALT enzymes of G2 group at 21 and 35 days of age, while the cholesterol concentration of G2 and G4 groups increased at 21 days of age compared to the rest of the groups.
