This study was carried out to investigate the effect of evening feeding to pregnant cows(Hanwoo) on calving time during a day. The investigation revealed that feeding at 17:00∼21:00 resulted in 79.8% of the cows calving between 06:00∼21:00, whereas the tradional 08:00∼09:00 and 17:00v18:00 feeding resulted in 59.3% of them calving during the time period (P$lt;0.001). There were no significant differences in the calving time, parity, feed intakes, calving days, and sex ratios between the two feeding practices.
