| Abstract: The objective of this work was to evaluate the performance, body composition, and physiological state of tambaqui (Colossoma macropomum) fingerlings fed diets containing different levels of green tea (Camellia sinensis) extract (GTE). A completely randomized design was used with five treatments, different levels of GTE (0.00, 0.05, 0.30, 0.55, and 0.80 g kg-1) and three replicates. The diets were offered to fingerlings twice a day, for 90 days. The increase of dietary GTE levels promoted a positive quadratic effect on body lipids, hepatic lipids, retention of body lipids, glucose, and total triglycerides, and the minimum values of these variables were estimated with 0.61, 0.54, 0.73, 0.60, and 0.30g kg-1 GTE in the diet, respectively. There was a... |
