How often will I change pastures

You want to try to graze pasture down to 3 inches to 6 inches in height. 5 paddocks will have you move your horses once a week, but in the spring on cool season grasses, you may end up with too much growth. to keep it all grazed down. Some of the pasture may need to be cut for hay. You want to try to keep the forage in a vegetative state as much as possible. Food quality goes down when plants have flowers and seed heads.
