Horses sleep standing up. This is possible because they lock their knees so they stay standing up. This is also helpful in the wild because if they are sleeping and a predator attacks them they can wake up and run quickly away without wasting time standing up.
However cows don't sleep standing up because they do not have the same sort of physiological advantages in their legs like horses do.
