Effect of Protein and Starch Level in Practical Extruded Diets on Growth, Feed Utilization, Body Composition, and Hepatic Transaminases of Juvenile Grass Carp, Ctenopharyngodon idella

Six practical extruded diets were formulated to investigate the effect of graded levels of starch (17, 22, and 26%) associated with either 30 or 34% protein level on growth, feed utilization, body composition, and hepatic transaminases of juvenile grass carp, Ctenopharyngodon idella . Over an 8‐wk growth trial, survival rates (99–100%) were not significantly affected ( P > 0.05) by dietary treatments. Independent of dietary starch level,...
