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.
In a 24 hour period, a cow will graze for around 14 to 16 hours per day, with the rest of that spent resting and chewing the cud. 2 people found this useful.
