This experiment was carried out to study the effect of supplementation culture cellulolytic bacteria (isolated from the rumen of buffalo) in the tofu-based ration on the growth performance of male Bali duckling up to ten weeks of age and N-NH3 concentrations in excreta. One hundred and twenty of male Bali drakes (Anas sp) were assigned to 4 treatments in a completely randomized design. The treatments were the tofu-based rations without supplementation culture cellulolytic bacteria as a control (A); supplementing rations at 0.20% cellulolytic bacteria culture (B); by supplementing 0.40% cellulolytic bacteria culture (C); and 0.60% ration supplemented culture cellulolytic bacteria culture (D), respectively. The study showed that supplementation of 0.40 to 0.60% cellulolytic bacteria culture in tofu-based rations could improve significant differences (P<0.05) on live weight gain (LWG)s, carcass percentage, and were efficient in using feed compared than control (A). On the other hand, abdominal fat, serum cholesterol contents, and the concentration of N-NH3 of the birds decreased significantly different (P<0, 05) than control. It was concluded that supplementation of 0.40 to 0.60% cellulolytic bacteria culture isolated from the rumen of buffalo in the tofu-based diets can improve on growth performance of male Bali duckling up to ten weeks of age. In contrast, significantly reduced the amount of abdominal fat, serum cholesterol contents, and the concentration of N-NH3 in excreta.
