ABSTRACT: Results of nutrient requirements as determined in dose-response trials are valid only for fish within the same size range of that of experimental model fish. This study used the factorial approach to estimate digestible energy (DE) and digestible protein (DP) requirements for maintenance and growth of pacu ( Piaractus mesopotamicus ). Juvenile pacu (63.5 ± 1.27 g) were stocked in a recirculation system (26.89 ± 0.36 °C) for 58 days, and fed two daily meals. One diet contained 6.96 % lipids (LF) and another 9.98 % lipids (HF), both diets formulated to contain 32 % crude protein, theoretical dietary energy level for maintenance (52.23 kJ DE kg−0.80 d−1), in a completely randomized, 2 × 5 factorial experimental design. The apparent digestibility...

In this research, energy and exergy loss were analyzed in the laboratory for the drying of eggplant using a fluidized bed dryer. The drying experiment was conducted at inlet temperatures of 40, 50, and 60  and air velocities of 3, 5, and 7 m/s using samples with diameters of 5, 10, and 13 mm and a height of 1 cm. The effects of temperature, velocity of drying air, and sample size on energy consumption and exergy losses were investigated. The results showed that the minimum energy consumption and exergy losses occurred at a diameter of 13 mm, velocity of 3 m/s, and temperature of 40. Meanwhile, the maximum energy consumption and exergy losses occurred at diameter of 5 mm, velocity of 7 m/s and temperature of 60;. Generally, the results demonstrated that...
