Digestibility of ingredients in diets for pacman catfish juveniles (Lophiosilurus alexandri)

The objective of this work was to determine the apparent digestibility coefficient (ADC) of six ingredients, in practical and purified reference diets, and to assess the influence of these reference diets on the digestibility of the ingredients in pacman catfish juveniles. The following ingredients were evaluated: fish meal, meat and bone meal, soybean meal, roasted whole soybean, wheat meal, and corn protenose. There was interaction between the reference diet and the studied ingredients. The purified diet provided higher ADC for crude protein and gross energy. Pacman catfish showed high ADC for protein ingredients of vegetable origin for the two reference diets.
