[Augmentation of nitrogen efficiency and hyperphagia associated with refeeding after prolonged fast in the domestic goose]

Abstract

The domestic goose is hyperphagic after a fast resulting in a 40% decrease in body mass (a decrease similar to that during breeding anorexia). Food intake is maximum on the 8th day of refeeding. As it is then an average of 2.5 times higher than before the fast, food intake may thus reach the value during forced-feeding for "foie gras". Since nitrogen assimilation rate also increases 2.5 times, nitrogen fixation is increased 6.8 times, suggesting a high level of protein synthesis.
