Abstract:
This study was performed to compare the effect of dietary supplementation of probiotics, prebiotics, essential oils and synbiotics on feed conversion ratio, live body weight and total feed intake of broiler chicken. A total of 800, day-old Arbor acres broiler chicks of either sex were randomly assigned into four dietary treatments. Each treatment had four replicates of 50 birds and were reared for over five weeks. Basal diet was supplemented with probiotics (control, T1), essential oils (T2), synbiotics (T3), and prebiotics (T4) as dietary treatments. The birds were provided with ad libitum feed and drinking water during the entire experimental period. At the end of 35 days experimental period there was no significant difference in live body weight, total feed intake and feed conversion ratio of broilers fed prebiotic, synbiotic and essential oil groups compared with probiotic supplemented control group. These findings reveal that, there is a potential to use prebiotics, EOs, and synbiotics as non-antibiotic growth promoters to improve broiler chicken’s growth performances
