Abstract The satiety mechanism can be expressed as the positive correlation between meal
length and the length of the preceding (preprandial) interval; the hunger mechanism as
the positive correlation between meal length and the length of the succeeding
(postprandial) interval. It has been suggested that broilers have a disturbed hunger and
satiety mechanism. This may be reflected especially in the preprandial correlations
since Burkhart et al. (1983, Behav. Genet. 13, 295-300) suggested that selection for
increased body weight damaged the hypothalamic satiety mechanisms leading to a
failure to diminish the hunger drive and consequently to overconsumption. An
experiment was conducted to measure length of eating bouts and intervals to calculate
pre- and postprandial correlations of male broiler- and layer chicks.
