Objective: The present study focuses on the use of Lactobacillus sp. as probiotics to the Red jungle fowl and to test its growth efficacy. Materials and Methods: The isolated colonies were optimized at different pH range and it was found that at pH 7 maximum O.D value of 0.725 was attained and that of Temperature optimization at 30{\textdegree}C showed a maximum O.D value at 0.624 when read at 600 nm. The optimized pH and temperature were used for the mass production of lactobacillus sp. for 3 days in orbital shaker and the biomass. The Biomass was fed to one month grown red jungle fowls , the biomass was mixed with commercial feed and the weight of the fowls were checked every 4 days interval to a total of 28 days. Results: A total of five colonies were isolated from the serial dilution performed on the nutrient agar medium and then it was streaked on MRS a specific medium for Lactobacillus sp. The isolated Lactobacillus sp. was given as a probiotic to the two test fowls and the weight of the fowls was 295 g on the 4th day and which increased gradually to 595 g on the 28th day. This shows that bacteria could be\ used as a probiotic to enhance the weight and quality of the chickens.
