They were divided into four groups with two replicates per group and 15 chicks per replicate. The treatments were T1 (control), T2 (supplement diet with 4g probiotic), T3 (supplement diet with 2g probiotic), T4 (supplement diet with 1g probiotic). The experimental feeding trials were conducted after two weeks adaptation period.Results: The present findings revealed that the chickens supplemented with Lactobacillus species probiotics during the first week of age have shown higher body weight than control (p < 0.05). The feed intake of week one of T2 and T3 were significantly higher (p< 0.05) than the T1 (control). However, there was no significant difference (p> 0.05) in feed intake in the 2nd, 3rd, 4th, and 5th weeks of all treatment groups. The present result showed that there was a significant body weight gain (p< 0.05) in all probiotic fed groups than the control group. The highest body weight gain was observed in chickens found in the T4 treatment group. Whereas the body weight gains significantly higher and improved the feed conversion (p< 0.05) in the T2 and T4 than the T1 (control). However, the feed conversion ratio was significantly influenced by probiotic inclusion in T3 as compared to the control group.Conclusion: Overall, the results suggest that Lactobacillus paracaseis sparacasei and Lactobacillus rhamnosus have a positive effect on the growth performance of broilers.Keywords: Body weight gain, Broiler, Chicken, Lactobacillus species, Probiotics
