Stephen Duren, PhD, an equine nutritionist at Performance Horse Nutrition, says horses age at different rates and the nutritional definition of old is when they can no longer eat a normal diet and maintain body weight.

Stephen Duren, PhD, an equine nutritionist at Performance Horse Nutrition, suggests that when you start figuring out a diet, to start with forage. "If an old horse, because of poor teeth, is not getting feed adequately chewed, we have to 'chew' it for him," says Duren.
Duren recommends completely covering the pellets or cubes with water so they soak it up and become soft. "Once the feed is fully moist, I don't add any extra water; the mass of pellets or cubes just grows in bulk as they take on water," he says. When using alternative fiber sources like beet pulp, these are soaked also.
Duren says there is also an emotional definition of when a horse is old - when he retires from a career. He may be put out to pasture just because he's no longer being ridden. "There's also a nutritional definition of old, when he can no longer eat a normal diet and maintain body weight," says Duren. When the body starts to change, regardless of what is affecting it, that's when you should think of the horse as geriatric and reconsider the diet.
Aging rate is affected by genetics as well as by the lifestyle the horse had earlier in his younger days. "If he had good care all his life and was never used hard, 'old' may be mid-twenties or early 30's. On the other hand, if a horse had a strenuous career, he may be arthritic and have old injuries," says Duren. An older horse may lose weight because he's stiff and not as aggressive in the herd, dropping down the pecking order and being chased away from the hay. Dental problems and loss of teeth can also be a factor and in many ways, a horse is only as "old" as his teeth.
