This complete supplement meets the needs of horses in all stages of life and performance. Nutrient for nutrient, Opt-E-Horse Complete is a better value and true time saver over feeding multiple supplements. Labeling includes feeding instructions for horses at various sizes, ages, workloads and phases of reproduction. The 3 lb. container provides a 45 to 90 day supply for one horse and the 25 lb. bucket provides a 40 to 80 day supply for ten horses. Both supply amounts depend on the condition and workload of the horses.
