Effect of Gum Arabic as Natural Prebiotic on Intestinal Ecosystem of Post-Hatched Broiler Chicks

The aim of the present study was to investigate effects gum Arabic supplementation on short-chain fatty acids, cecal microbiota, immune-related gene expression, and small intestinal morphology in post-hatched broiler chicks. On day hatching, 6 dietary treatments were randomly allocated a total 432 commercial male Each treatment included 12 cages with chicks per cage repeated. Dietary (T1 T6) supplemented 0.0, 0.12, 0.25, 0.50, 0.75, 1.0% basal diet, respectively. Performance parameters, acid concentration, quantification microbiota immune response expression (pre-inflammatory cytokines, mucin-2, secretory immunoglobulin A), histomorphometry intestine measured. According our results, daily weight gains T2 production efficiency index increased T4, whereas feed intake decreased T2, T3, T5, T6, but conversion ratio improved.
