A 60-day dietary trial was conducted in twelve fiberglass tanks, each with a capacity of 300 L and stocked at a density of 50 fish tank−1, to investigate the influence of different combinations of synbiotics between Pediococcus pentosaceus and Fructooligosaccharide (FOS) on the growth rate, feed efficiency, digestive enzyme activities, hematological profiles and lysozyme activity of rabbitfish. Fingerlings weighing 5.10±0.28 g were fed with synbiotics containing FOS alongside varying masses of P. pentosaceus cells, including 107 CFU g−1 (NT1), 108 CFU g−1 (NT2), and 109 CFU g−1 (NT3). Meanwhile, a control group received a basic diet containing 0.5 % FOS without P. pentosaceus supplementation. The trial was performed in triplicates. After 60 days, the addition of synbiotics significantly improved the growth rate, feed efficiency, digestive enzyme activities, hematological profiles, and lysozyme activity of Golden Rabbitfish across all dietary treatments. The results indicate that supplementing the diet of golden Rabbitfish with synbiotics containing P. pentosaceus and FOS, particularly P. pentosaceus at a concentration of 108 CFU g−1, is advisable to enhance the overall growth rate, feed efficiency, and health status of the fish. |
