Fewer topics in equine nutrition stir more controversy than feeding the growing horse. Many factors add to the confusion of providing nutrition throughout these critical stages of life. For example, growing horses may have different commercial end points. Some will be shown in halter futurities where maximum growth and condition are required at a young age. Others will be prepared for sale, also requiring a ‘well-grown’ individual and many will be kept on the farm to be used as replacement horses or future performance horses.
