Body weight of broilers was significantly (P<0.01) influenced by all the dietary supplementation. Significantly {P<0.01} lesser feed was consumed by the birds raised on Lactobacillus sporogenes supplemented diet. Dietary supplementation of Virginiamycin and Lactobacillus sporogenes either independently or simultaneously improved the feed efficient significantly (P<0. O1) when compared to control group. Dietary supplementation of Lactobacillus sporogenes and Virginiamycin increased the livability percentage of broilers.en-USVeterinary SciencePoultry ScienceArticle
