Ninety Cobb-500 straight run broiler chicks were allotted into three dietary groups; D1 (Control diet), D2 (diet with 0.5g Bacillus Subtilis/kg diet), D3 (diet with 10g Spirulina Platensis/kg diet) having 3 replicates in each and 10 chicks/replicate. The birds were reared on a littered floor management system for 35 days of age and fed a starter diet (0-14 days) that contained 22% CP and 2900Kcal ME/kg diet and a finisher diet (15-35 days) contained 19% CP and 3000Kcal ME/kg diet. Dietary groups did not differ statistically for the body weight, feed intake, FCR, mortality, cost of production, and net profit (p˃0.05). However, diet D2 tended to perform the best among the 3 diets in terms of body weight, feed intake, FCR, mortality, production cost, and net profit. Of the two diets, D1 tended to show lower production costs and a higher net profit compared to D3. The highest dressed meat yield and heart weight were noted in D1, followed by D3 and D2, respectively. Hence, diet D2 was comparable to diet D3 in the case of meat yield traits. Diets were found to be similar in total cholesterol, Triglyceride (TG), Low-Density Lipoprotein (LDL), and High-Density Lipoprotein (HDL) (p<0.05). However, D2 tended to be the lowest for total cholesterol, and LDL, and the highest for HDL, followed by D1 and D3, respectively. Therefore, Bacillus Subtilis (0.5gBS/kg diet=D2) may be beneficial for broiler production
