Resumo
Apparent digestibility (ADC) of five isoproteic and isoenergetic diets containing 0, 0.1, 0.2, 0.3, and 0.4g/kg of
enzymatic complex BioEnzimaplus (lipase, protease, and carbohydrase) for Nile tilapia was evaluated. A
hundred fish were randomly assigned in five feeding aquaria, and five collecting feces ones. Treatments were
composed by five enzymatic complex levels arranged in a completely randomized design in five repetitions.
Significant differences (P<0.05) were observed with the inclusion of enzymatic complex in the diets for ADC of
crude protein and fat (linear effect). ADC of crude protein and fat varied from 81.60% to 84.94% and 74.19%
to 85.69%, respectively. The highest enzyme supplementation level showed better digestibility values for
carbohydrate and gross energy (57.85% and 63.78%, respectively). No difference was observed for ADC of dry
matter showing values between 49.47% and 58.55%. The use of enzymes in Nile tilapia diets improved the
digestibilities of protein, fat, carbohydrate, and gross energy digestibility.
