摘要: Abstract The present study was conducted to investigate the effects of size-fractionated fish hydrolysates on growth, activities digestive enzymes and aminotransferases expression some protein metabolism related genes in large yellow croaker ( Larimichthys crocea ) larvae. Fish (initial body weight 3.15 ± 0.15 mg) were fed for 30 days with four diets: control diet produced using meal (FM) as main source other three diets formulated permeate after ultra-filtration hydrolysate (PUFH), retentate (RUFH) or non-ultrafiltered (NUFH) replacing approximately 40% FM. results showed that specific growth rate survival significantly lower NUFH RUFH than P > 0.05). Specific ratio “pancreatic enzyme intestinal segment/pancreatic pancreatic segment” not different between PUFH they both higher These suggest when FM, seems optimal larvae compared could affect digestion absorption by altering mRNA levels CCK, PepT1 trypsin.
