Investigation of synbiotic effect of Primalac and Fermacto on performance, ileal nutrients digestibility, intestinal mucosal morphometry and some blood biochemical parameters of broiler chickens

To evaluate the effects of Primalac probiotic and Fermacto prebiotic, alone or combined, on growth performance, ileal nutrients digestibility, intestinal mucosal morphometry and some blood biochemical parameters, a trial was conducted using 256 broiler chicks (Ross 308) by employing a completely randomized design. Four treatments including Avilamycin antibiotic (control), Perimalac, Fermacto and Perimalac plus Fermacto with four replicates were added to the basal diets and fed to birds for a period of 42 days. Primalac and Fermacto decreased feed intake (P
