Many commercially prepared grain mixes (concentrates) contain a high percent of molasses. Some are as high as 15 percent. "Sweet feeds" were among the first commercial horse rations manufactured. While molasses may improve acceptability of rations to the horses, high levels of 10 to 15 percent are not required to accomplish this. Molasses at levels of 5 to 8 percent will help to decrease dust and sorting of fines in rations. Molasses is low in protein and phosphorus. However, molasses is considered a good source of energy. But other energy sources are less expensive based on the amount of energy provided per pound of ingredient. Most of the common grains fed to horses will supply more energy per pound at a lower cost.
