Abstract
This study evaluated the hypothesis that current commercial methods for raising poultry are inadequate for rest to occur. In order to test this hypothesis, heart rate and heart rate variability were measured during light and dark periods. There were no sign&" dif???erences in these variables, which suggests that 1-hr dark periods are insufficient for sleep to occur.
