[Metabolic study of the initial period of fasting in the king penguin chick].
There is an 80% decrease in the specific daily change in body mass (dm/m dt) during the first 5-6 days of fasting in king penguin chicks, which characterizes period I of fasting. Parallel decreases in plasma alanine and uric acid concentrations suggest an important reduction in protein degradation. Plasma concentration of beta-hydroxybutyrate and glucose are high, respectively 1.3 and 12.5 mmol X 1(-1), and do not change significantly.
