Effect of Using Prebiotics, Probiotics and Synbiotics as Feed Additives on Performance and Carcass Quality of Broiler Chickens

摘要

Day old cobb-400 broiler chicks (240 nos.) were randomly assigned into four dietary treatments each with three replicates of 20 chicks. Four experimental diets were formulated as control diet (T_1) without probiotics, prebiotics or synbiotics supplementation, while, birds in group T_2, T_3 and T_4 were fed with diets containing prebiotics (500g/ton of feed), probiotics (l00g/ton) and a combination of prebiotics and probiotics (250g/ton+50g/ton) respectively. Broilers fed with probiotics had shown significantly (P<0.05) higher feed intake. Body weight, body weight gain and efficiency of feed utilization of birds were superior with synbiotics supplemented feed. Further, no adverse effect of prebiotics, probiotics or synbiotics supplementation was observed on sensory parameters and chicken meat of control. The results obtained revealed that synbiotics and probiotics can be added in broiler ration as a viable alternative to antibiotic growth promoters for the feeding of broiler chicken.
