Citrus citrus peeling has a wide range of vitamins and trace minerals that have antioxidant and antimicrobial properties. It is hypothesized that the addition of citrus peeling to broiler quail diets can improve their production performance, humoral immunity, nutrients, and energy utilization. A trial was performed to study the impact of a methanolic extract of citrus peeling (Citrus sinensis) on production performance, humoral immunity, nutrients, and energy utilization of broiler quails. A healthy day-old 300 quails were randomly assigned with 5 replicates each replicate had 15 birds and used CRD for the trial. Different dietary supplementations were presented to different groups. The control group was not supplemented with any supplementation in their feed. While, the 3 other groups were supplemented by 0.5 mL/kg, 1 mL/kg, and 1.5 mL/kg of methanolic extract of dried Citrus sinensis peel (DCSP) in the basal diet (DCSP0.5, DCSP1, and DCSP1.5 groups, respectively). All the birds were allowed ad libitum feeding and water. The feed intake and FCR were significantly higher in the control group, followed by DCSP0.5, and then DCSP1. The significantly lowest feed intake and FCR were observed in the DCSP1.5 group. The weight gain and dressing % were significantly improved with the increasing level of methanolic extract of Citrus sinensis. The significantly highest weights of thymus, spleen, and bursa were recorded in the DCSP1.5 group, followed by the DCSP1. The antibody titers aga...
