| Abstract | ||||
| Phytase enzyme supplementation in feed is expected to increase the bioavailability of phosphorus and other nutrients.[Y1] [A2] The present study aimed to evaluate the effect of phytase enzyme supplementation in feed on growth, mineral digestibility, amino acid digestibility and body chemical composition of common carp (Cyprinus carpio L.) fed with soybean meal at the rearing stage. The study used common carp fish with an average weight of 18.82 ± 0.26 g/head. The experimental feed was floating pellets supplemented with various doses of phytase enzyme: 0 (A), 500 (B), 1,000 (C) and 1,500 (D) FTU/kg feed. [Y3] [A4] Mineral content (Ca, Mg, Fe, Cu, Zn and Mn) was analyzed from the dried fish feces using a polarized atomic absorption spectrophotometer. While Na and K contents were determined using a flame photometer, and P content was calorimetrically analyzed. The feed utilization efficiency (EFU), feed conversion ratio (FCR), protein efficiency ratio (PER), relative growth rate (RGR), survival rate (SR) and protein digestibility (ADCp) were determined. The results showed that common carp fed with 1000 FTU/kg phytase enzyme (C) exhibited the highest PER, FCR, EFU and RGR values, compared to other experimental feeds. Common carps given 1000 FTU/kg phytase enzyme (C) recorded the highest mineral values, including Ca, P, Na, K, Mg, Fe, Cu, Mn and Zn. Therefore, phytase enzyme supplementation in feed significantly (P<0.05) increased the growth, mineral digestibility, protein content and amino acid digestibility of C. carpio. The phytase enzyme at 1000 FTU/kg of feed was the best dose for common carp at the rearing stage.[Y5] [A6] [Y1]The background is too long. I recommend to reduce it [A2]I have reduced the background [Y3]Your research parameter did not mention in method including with its assay [A4]DONE [Y5]Please improve your results with value in each parameter And also add the conclusion [A6]DONE | ||||
