Phytase Enzyme Improves Growth Performance and Body Chemical Composition of Sangkuriang Catfish (Clarias gariepinus var. Sangkuriang) Juvenile

Due to their nutritional value, alternative vegetable materials such as soybean are needed promote sustainable aquaculture development. However, phytate in could interfere with the protein digestion of fish body. This study examines effectiveness enzymes enhancing digestibility, growth performance, mineral digestion, and body chemical composition Sangkuriang catfish (Clarias gariepinus var. Sangkuriang) juveniles. The was completely randomized design 4 treatments 3 repetitions. One hundred thirteen juveniles (7.65 ± 0.14 g) were used for each repetition. fed an experimental diet supplemented various doses phytase enzyme: 0 (A), 500 (B), 1,000 (C), 1,500 (D) FTU/kg feed. efficiency ratio (PER), feed conversion (FCR), utilization (EFU), apparent digestibility coefficients (ADCp), relative rate (RGR), survival (SR) observed. Data analyzed using analysis variance followed by Duncan’s multiple range test. results showed that adding enzyme (C) exhibited highest PER, FCR, EFU, ADCp, RGR value compared other treatments. All treatment groups (B-C) had same SR (100%) crude ash content A group. group also a higher phosphorus, calcium, potassium, magnesium, iron, zinc, manganese, copper, cobalt. Therefore, supplementation improve
