The growth of the aquafeed sector is highly dependent upon the availability of fish feed with a balanced nutritional composition. The use of prebiotics and probiotics can be an effective solution to increase the bioavailability of feed components. In this study, we evaluated the effect of dietary supplementation with β-propeller phytase (0, 600, 1200, 1800 and 2400 U/kg) from Bacillus and mannan oligosaccharide (MOS) (0, 2, 4 and 8 g/kg) on growth performance and nutrient digestibility of Nile tilapia over 45 days. The findings showed that adding phytase significantly (p Bacillus and MOS increases growth performance and nutrient digestibility.
