The study assessed the protein sparing effect resulting from carbohydrate (CHO) and lipid (LIP) use and metabolic responses of juvenile tambaqui fed diets with different proportions of CHO and LIP. In a completely randomized 3 × 2 factorial design, the 6 diets tested combined 3 CHO (410 gkg-1, 460 gkg-1 and 510 gkg-1) and 2 LIP (40 gkg-1 and 80 gkg-1) levels. The 1080 fish tested (10.88 g ± 0.13 g mean body weight) were randomly distributed into twenty-four 500-L tanks (45 fish per tank). An increase in diet CHO and LIP levels improved feed conversion and protein efficiency ratio. The highest addition of CHO (510 gkg-1) and LIP (80 gkg-1) reduced diet intake and weight gain and increased serum triglyceride levels and fat deposition in muscle and liver. Glucose levels, serum protein and liver glyc.. View More»
