Farnam Weight Builder is a powdered feed supplement packaged in a bucket for horses that need additional calories to maintain or build body condition. The formula is built around ingredients such as dehydrated maize distiller's grains, heat-stabilized flax meal, and partially hydrogenated vegetable fat to deliver a concentrated source of fat-derived energy. No sugar is added, making the powder an easily digestible way to add calories without increasing grain volume. A measuring scoop is included so the supplement can be portioned and mixed into the horse's regular daily grain ration. Omega-3 fatty acids in the formula are intended to support healthy skin and a glossy coat, while supplemental calcium helps maintain a balanced calcium-to-phosphorus ratio. The supplement is intended for horses across different classes, including performance, mature, underweight, and senior animals that need extra caloric support.
