Table 1 Muscle composition of hybrid bagrid catfish fed experimental diets containing graded levels of Ile for 8 weeks

From: Dietary isoleucine improved flesh quality, muscle antioxidant capacity, and muscle growth associated with AKT/TOR/S6K1 and AKT/FOXO3a signaling in hybrid bagrid catfish (Pelteobagrus vachelli♀ × Leiocassis longirostris♂)
