Senior horses have specific nutritional needs that change as they age, with inadequate nutrition in older horses being a significant and often preventable welfare problem.
Nutritional neglect of senior horses is a welfare problem that is sometimes rationalized as the natural consequence of aging. A thin 25-year-old horse is not inevitably thin because of age - it may be thin because of dental disease preventing adequate hay chewing, PPID reducing metabolic efficiency, or simply inadequate caloric provision for its actual needs. The welfare solution requires distinguishing between normal aging and treatable conditions: dental assessment to identify problems preventing effective chewing, health screening for PPID, and body condition scoring to monitor nutritional status objectively. Senior horses often need more, not less, nutritional support than their middle-aged counterparts, and providing it significantly improves quality of life.
