title: [Metabolic adaptations to prolonged fasting in birds].
abstract: Because they tolerate remarkably long periods of fasting, birds appear as interesting models to study the mechanisms for decreasing metabolic rate and sparing proteins. In particular, the comprehension of the metabolic changes occurring during the three periods of fasting which have been characterized, might be helpful for determining the possible role of ketone bodies in the adaptation to long-term fasting.
