Combined supplementation of L-carnitine and stevioside enhances performance, stress tolerance, immune competence, and molecular responses in Nile tilapia
This study evaluated the individual and combined effects of dietary L-carnitine (500 mg/kg) and stevioside (450 mg/kg) on growth performance, physiological responses, stress tolerance, immunity, antioxidant status, and molecular regulation in Nile tilapia (Oreochromis niloticus; initial weight 3.84 ± 0.12 g) over 90 da...
