| Knowledge of the digestibility coefficients enables the preparation of rations that meet the nutritional requirements of animals through the knowledge of the use of nutrients in foods. The aim of this study was to determine the digestibility coefficients of crude protein from poultry by-product meal and tilapia filleting by-product meal for piavuçu (Leporinus macrocephalus) juveniles. A total of 60 piavuçu juvenile with initial average weight of 75.05 ± 12.62 g, were distributed in three collecting tanks with capacity of 90 liters for feces collect. The feeding was carried until the apparent satiety in adaptation phase of 40 days. Four times a day 8h00, 11h00, 14h00 and 17h00. In the feces collection period, the fishes were fed at 8h00, 12h00 and 14h00... |
