• Effect of Feeding Frequency on Hepatopancreatic Enzyme Activities and Body Composition in Carp, Cyprinus carpio.

抄録

In order to investigate the effect of feeding frequency on the hepatopancreatic enzyme activities and the serum and body compositions, carp, Cyprinus carpio were fed on a commercial diet once or 3 times a day for 30 days in the experiment 1 and on a glucose-based diet once or 4 times a day for 40 days in the experiment 2. The growth, protein retention, and hepatopancreatic fat content were lower in the fish fed once a day than in those fed several times a day in both experiments. The activities of lipogenic enzymes such as glucose-6-phosphate dehydrogenase and NADP-malate dehydrogenase were not affected by feeding frequency. In both experiments, the activities of gluconeogenic and amino acid-degrading enzymes such as glucose-6-phosphatase and aspartate aminotransferase were somewhat high in the fish fed once a day. These results suggest that the extremely low feeding frequency slightly accelerates amino acid degradation and gluconeogenesis in the hepatopancreas of carp, resulting in a low protein retention.
