Abstract :

The aim of the experiment was to investigate the effects of dietary supplementations of prebiotic, synbiotic and organic acid as alternative to antibiotic on growth performance and carcass characteristics of broiler chickens. A total of 240 day-old Arbor Acres broiler chickens of either sex were randomly assigned to five dietary treatments each consisting of four replication and each replicate having 12 birds for 5 weeks. The dietary treatments were (1) control group with basal diet, (2) Basal diet supplemented with antibiotic (at 250 gm/100 kg of starter as well as finisher ration), (3) Basal diet supplemented with probiotic (at 10 gm/100 kg of starter as well as finisher ration), (4) Basal diet supplemented with synbiotic (at 25 gm/100 kg of starter ration as well as finisher ration), and (5) Basal diet supplemented with organic acid (at 150 gm/100 kg of starter as well as finisher ration). The birds were provided with ad-libitum feed and drinking water during the entire experimental period. The highest body weight observed in a probiotic group, which was non-significantly (p>0.05) higher than the control group. Antibiotic, synbiotic and organic acid groups showed lower body weight than probiotic group. A total feed intake did not show any significant (p>0.05) difference between experimental groups. There were no significant (p>0.05) differences in feed conversion ratio of broiler chickens in antibiotic, prebiotic, synbiotic and organic acid groups as compared with control group. There was no significant (p>0.05) difference in the carcass traits with respect to dressing percentage, carcass percentage, heart weight, liver weight and gizzard weight, wing percentage, breast percentage, back percentage, thigh percentage, and drumstick percentage in Arbor Acres broilers under study. The growth performance and percentage of carcass yield did not show any significant difference by the dietary inclusion of antibiotic, probiotic, synbiotic, and organic acid compared with un-supplemented control in a commercial broiler chicken. So that it is easily conclude that, probiotic, synbiotic, and organic acid can be used as alternatives to antibiotic.
