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.
Adult horses sleep for about four hours a day on average. However, they do not sleep for long periods of time like humans. They take a number of shorts naps which add up to about four hours.orse's sleep requirements are much different than humans. Horses can doze standing up and spend an hour or two each day with 'on the ground sleep'. But if they are completely â¦ deprived of sleep they would start to feel the effects after 2 or 3 days.
