Slow feeders are designed to help your horse slow down his hay consumption. By doing this, you can feed in sync with the way horses are designed, by offering a steady flow of forage at all times, 24/7, all day and all night. The hormonal response calms down, allowing the horse to better release body fat for energy.
They come in a variety of styles and mesh sizes, shown below.
