Standing vs. Lying Down. It's a common misconception that cows don't lie down to rest and that they sleep standing up, just like horses do much of the time. In fact, cows actually lie down for up to 14 hours per day, standing up every few hours, stretching and then lying back down again.
Pasture intake is related to the amount of time spent grazing, the number of bites per minute, and the size of each bite (Phillips et al. 1988). Dairy cattle generally graze for six to nine hours per day. Because of a cow's need to ruminate and rest, she seldom grazes over nine hours per day.The number of bites taken per minute does not vary appreciably, ranging from 55 to 65 bites per minute.airy cattle generally graze for six to nine hours per day.
