Does a horse need to eat grass all day if he is in a field?
A horse left on it’s own will eat about 12 times a day, so it may seem like the horse is eating all day. They eat smaller meals very frequently because it is better for their digestive systems. Most horses love fresh grass as well so they will tend to eat a lot of it when they have the opportunity. This however can be very dangerous in the spring time though. A lot of fresh grass can cause a horse to founder, and once a horse has been foundered there is no curing him, so in the spring it is best to re adjust their digestive systems slowly, by allowing them time to graze in small time intervals, maybe at first as short as 15 or 20 minutes, and then gradually increase the time they have fresh grass available to them so it does not shock their systems.
