The use of antibiotics as growth promoters was completely banned in 1999 by the European Union (EU) European commission (2001). This was due to increases in microbial resistance to antibiotics and residues in chicken meat products which might turn to be harmful to the human consumers. Currently, in many parts of the world, feed additives such as probiotics and prebiotics are being experimented to alleviate the problems associated with the withdrawal of antibiotics from feed. The aim of this study was to investigate whether Lactobacillus sporogenes could improve the growth performance, feed conversion ratio and meat quality in broiler chicken. Approach: A total of 200 broiler chicks were randomly assigned to 4 treatment groups, consisting of 2 replicates of 25 birds each. Commercial mash pre-starter, starter and finisher diets were supplemented with 50, 100 and 150 ppm of L. sporogenes. Results: Growth performance was better in all the experimental groups than the control. Feed conversion ratio and TBA value were lowered in birds supplemented with 100 ppm of L. sporogenes. Conclusion: This study concludes that supplementation of L. sporogenes to the broiler diet could improve the growth performance, decrease feed conversion ratio and TBA value, it could be recommended that addition of L. sporogenes at 100 ppm (100 mg/kg) could improve the growth performance of broiler chicken.
