To investigate the effects of dietary fumaric acid (FUA) on performance, carcasses, nutrient digestibility, blood metabolites, digestive enzymes, and cecal microbiota in Japanese quail chicks. Three hundred unsexed (1-wk-old) were randomly assigned to 5 groups. Supplementation FUA diet chicks exhibited a significant improvement growth performance through different experimental periods studied compared with those receiving unsupplemented one. The digestibility crude protein (CP) metabolizable energy (ME) improved 10 15 g/kg FUA, respectively. Apart from lipase enzyme, birds fed recorded higher activity amylase. There no changes among groups relative weights carcass, gizzard, heart, dressing. Dietary supplementation at levels (P> 0.05) increased total (TP) globulin (GLB) concentrations A/G % control group. A (P < 0.01) decrease plasma low density lipoprotein (LDL) cholesterol (TC) increase high (HDL) observed containing diets. Immunoglobulin G (IgG) = 0.0026) M (IgM) 0.0007) greater treated either or g FUA/kg diet. Ca concentration was noticed received FUA/ kg other Quail diets reduced count coliform, E. coli, Salmonella as In conclusion, (especially diet) chick their growth, nutrients, immune response, antioxidant status, intestinal health.
