Rice bran is the outer brown layer of the rice kernel. Rice bran horse feed is created when rice is milled to create white rice for humans. To be used as a horse feed, rice bran needs to be stabilized to prevent spoiling. The rice bran stabilizing process involves heating the bran enough to inhibit the enzyme lipase from breaking down, and making the fat in the bran turn rancid.
Stabilized rice bran is fortified with calcium, and is high in B vitamins like thiamine, niacin and B6. Stabilized rice bran feed is available in pellets and meal formulations.
Stabilized rice bran for horses is a highly digestible source of fat, and is a rich source of calories.
