Effect of Supplementation of Synbiotic (β-Glucans, MOS and Multi-species Probiotic) on Growth Performance, Carcass Characteristics and Gut Health in Broilers

Abstract

An experiment was aimed to study the effect of supplementation of synbiotic (β-glucans, MOS and multi-species probiotic) on growth performance, gut health and carcass characteristics in broiler chicken. Two hundred and fifty (250) day old broiler chicks were randomly allotted to five dietary treatments with ten replicates of five birds in each. The treatments consist of a control diet based on corn-soybean without antibiotic as negative control (NC), with antibiotic growth promoter (Lincomycin @100g/MT) as positive control (PC), three experimental diets consist of probiotic (Bacillus subtilis, B. coagulans, B. licheniformis and Saccharomyces boulardii) @ 200g/MT, prebiotic (MOS & β-glucans) @ 500g/MT and synbiotic (Bacillus subtilis, B. coagulans, B. licheniformis and Saccharomyces boulardii, MOS & β-glucans) @ 200g/MT. The feed and water were offered ad libitum. The results revealed that supplementation of different dietary treatments did not affect (P>.05) the growth parameters such as body weight gain and feed intake of broilers and carcass parameters at 42 d of age. Supplementation of synbiotics was significantly (P<.05) lowered FCR in broilers. At 42 days of age, broilers fed synbiotic diet exhibited improved gut microbiota (lowered E. coli and increased Lactobacilli counts) and increased villi height compared to other dietary treatments.
