Özet

This study investigated the effects of exogenous lipase supplementation on the growth performance, digestive enzyme activity and body chemical composition of Sparus aurata L. A total of 840 Sparus aurata (7.72 ± 0.05 g) were fed eight diets for 60 days. Diets were coded Group 1: Control 1 (G1–14% Lipid); Group 2: Control 2 (G2–22% Lipid); Group 3: 14% Lipid + 0.5 g lipase (G3– 0.5 g/kg); Group 4: 14% lipid + 1.0 g lipase (G4–1 g/kg); Group 5: 14% Lipid + 1.5 g lipase (G5–1.5 g/kg); Group 6: 22% lipid + 0.5 g lipase (G6–0.5 g/kg); Group 7: 22% Lipid + 1.0 g lipase (G7—1 g/kg) and Group 8: 22% Lipid + 1.5 g lipase (G8–1.5 g/kg). There were 8 dietary treatments that included a protein and lipid diet containing (14% and 22%), crude protein (50%) and supplemented with graded levels of exogenous lipase supplementation activity at 0.5, 1, 1.5 and 2 g/kg diet. As a result of the study, G3 group was better in the final weight (64.42 ± 1.06 g), the specific growth rate (3.55 ± 0.01) and the feed conversion rate (1.20 ± 0.18) compared to other groups (P <0.05). Protease, trypsin and alkaline phosphatase activity support growth and their activity increased during the trial. As regards amylase, lipase and aminopeptidase, a decrease in their activity was detected during the research.
