Horses that had participated in Western\nequestrian disciplines were more likely to have a history\nof lameness. Among old horses, those with pituitary\ndysfunction were more likely to have a history of\nlaminitis than those without pituitary dysfunction.\nGeriatric horses were more likely to have long hair\nand shedding abnormalities than were younger horses.\nOwners perceived their horses as old at approximately\n22 years of age. In horses older than 16.5\nyears of age, age was a negative factor in the purchase\nof horses.<\/jats:p>\n\t\t\t\t<jats:p>\n\t\t\t\t\t<jats:bold>Conclusions and Clinical Relevance<\/jats:bold>\u2014Geriatric and\nyoung horses share some similar health problems,\nbut old horses have distinct health problems and veterinary\nmedical requirements. The management and\nathletic history of horses may influence health as they\nage.
