Abstract
The experiment was conducted to study the effects of dietary supplementation of prebiotic, probiotic and synbiotic as an alternative to antibiotic growth promoter on performance of commercial broilers. Two hundred and twenty four (224) straight run day-old commercial broiler chicks were distributed randomly to seven treatment groups, each treatment group consisted of four replicates, each of 8 chicks leading to 32 chicks per treatment. The experiment was conducted for a period of six weeks. The seven treatments were divided as follows: T1 diet was kept as control (without antibiotic and without prebiotic, probiotic and synbiotic). T2 diet contained bacitracin methylene disalicylate (BMD) as AGP @ 50g/100 kg feed, T3 diet contained prebiotic [Mannan-oligosaccharides (MOS) @ 0.05%], T4 diet contained probiotic-1 (Lactobacillus and Saccharomyces spp. @ 0.05%), T5 diet contained probiotic-2 (Clostridium and Bacillus spp. @ 0.05%), T6 diet contained synbiotic-1 (MOS @ 0.05% + Lactobacillus and Saccharomyces spp. @ and T7 diet contained synbiotic-2 (MOS @ 0.05% + Clostridium and Bacillus spp. @ 0.05%).
