Senior Horse Nutrition: Meeting Changing Needs with Age

Older horses have specific nutritional requirements that differ from younger animals, and meeting these needs is central to maintaining quality of life.

Key Facts

Horses are generally considered senior from age 15 to 20, though individual variation is significant.
Dental changes including tooth loss and smooth teeth reduce the ability to process long-stem forage.
Senior horses often struggle to maintain body condition despite adequate feed due to reduced digestive efficiency.
Soaked hay cubes or chaff, complete senior feeds, and mashes are common dietary adaptations.
Protein quality becomes more important than quantity in older horses due to reduced amino acid absorption.
Pituitary pars intermedia dysfunction, also called Cushings disease, affects a significant proportion of senior horses.
Annual body condition scoring and dental evaluations are standard components of senior horse care.

Welfare Considerations

Senior horse welfare frequently declines because nutritional inadequacy is masked until body condition loss becomes severe. Owners who continue feeding identical diets to ageing horses without reassessment expose animals to progressive malnutrition. Dental pain from sharp points, missing teeth, or periodontal disease often goes unrecognised, causing horses to drop food, lose weight, and avoid eating despite hunger. Cushings disease causes additional metabolic complications including laminitis risk and immune suppression. Proactive dietary assessment and biannual veterinary dental examinations prevent suffering that is otherwise invisible until late and difficult to reverse.

What You Can Do

Schedule biannual veterinary dental checks for horses over 15 years of age.
Body condition score your senior horse monthly and adjust diet when changes are detected.
Transition to soaked or soft feeds if your horse struggles to chew long forage effectively.
Test senior horses for Cushings disease via ACTH blood sampling, especially in autumn.
Consult an equine nutritionist to design a diet meeting the specific needs of your senior horse.
