•Dietary supplementation of both SB and SP improved growth performance of Oreochromis niloticus.•Dietary inclusion of SB and/or SP enhanced cultured tilapia health status.•Dietary inclusion of SB and/or SP amended intestinal histomorphology of Nile tilapia. The present study evaluated the possible synergistic impacts of sodium butyrate and Spirulina platensis as a feed additive on growth performance, carcass composition, blood health, and intestinal histomorphology of Nile tilapia (Oreochromis niloticus). A control and three treated diets were supplemented with sodium butyrate (SB) 350 mg, Spirulina platensis (SP) 1g and a mixture of 350 mg SB and 1g SP/kg diet (SB/SP) respectively, were fed for monosex Nile tilapia (12.5± 0.50 g, n=120) for two months. The results revealed higher growth performance (final weight, weight gain, weight gain rate, SGR and PER) compared to control group (CG) (P
