This is a custom sweet feed mix. The owner, who has a large number of horses specifies what they want included. The feed is delivered either by the bag or with a bulk truck that fills a large bin. This particular feed has oats, corn, molasses and a mineral supplement. Many feed companies make thier own sweet feeds for owners who may only need small quantities. One precaution with sweet feed in hot humid weather: if the molasses content is high, and the feed sits for a long time, it can begin to ferment or mold.
