摘要: Purpose: The present studies were conducted to evaluate the optimum inclusion levels of probiotic Bacillus coagulans, isolated from intestine Catla catla for improved growth performance and nutrient retention. Methods: fingerlings (avg. wt. 0.2±0.02 g) fed on isocaloric isonitrogenous diets supplemented with 2×104 (D1), 2×105(D2) 2×106(D3) coagulans cells 100g-1 feed 90 days @ 4 % body weight per day in two equal installments three replicates. control treatment (DC) was not coagulans. Growth digestibility parameters intestinal enzyme activities monitored. Results: fish terms live gain (g), percentage specific rate significantly (P
