Abstract
The daily rumination time (DRT) and the nycterohemeral pattern of rumination were recorded in six ewes before mating and during late pregnancy and in one unmated ewe. The mean DRT was shorter during pregnancy (mean: 329 min/day) than before mating (mean: 435 min/day). The DRT of the unmated ewe remained constant. The nycterohemeral pattern of rumination changed little during the trial.
摘要
