Beet pulp molasses is a popular, digestible fiber supplement for livestock, especially horses, made from leftover sugar beet fibers with added molasses for taste, energy, and reduced dust, available in pellets or shreds, offering energy similar to oats without the starch, but it's higher in sugar and needs moderation for metabolic horses, often used as a tasty carrier for medications. It's versatile, supports gut health, and is used for weight gain, picky eaters, and as a general energy source for various animals.
