Novel insights into choline's role in promoting myofiber hypertrophy and mitochondrial function in muscle of sub-adult grass carp (<i>Ctenopharyngodon idella</i>).

ABSTRACT: Choline is an essential nutrient for fish, and its metabolites are components of all membrane systems. Membrane phospholipids play an important role in maintaining the morphology and function of mitochondria, which could affect the growth and development of myofiber. To evaluate the effects of choline on growth performance, muscle fiber development, and mitochondrial morphology and function in grass carp, six diets containing graded choline levels [154.0 (basal diet), 321.8, 672.2, 1024.9, 1373.2, and 1722.8 mg/kg] were fed to 450 sub-adult grass carp (583.44 ± 1.65 g) for 56 d. The fish were divided into six groups with three replicates of 25 fish each. The results showed as follows: 1) compared with the control group, choline increased the growth performance, muscle protein content and c
