Effect of dietary Clostridium autoethanogenum protein on growth, body composition, plasma parameters and hepatic genes expression related to growth and AMPK/TOR/PI3K signaling pathway of the genetically improved farmed tilapia (GIFT: Oreochromis niloticus) juveniles

Abstract This study investigated the effect of dietary Clostridium autoethanogenum (C. autoethanogenum) protein on growth, whole-body composition, plasma parameters, and hepatic genes expression related to growth and AMPK/TOR/PI3K signaling pathway of the genetically improved farmed tilapia (GIFT:Oreochromis niloticus) juveniles. The fish (initial weight of 0.7 ± 0.05 g) were fed with diets containing C. autoethanogenum protein at 0 g/kg (Control, diet 1), 50 g/kg (Diet 2), 100 g/kg (Diet 3), 150 g/kg (Diet 4) and 200 g/kg (Diet 5) to partially replace mainly soybean meal in triplicates. After 8 weeks feeding trial, the growth was significantly (P
