Can they eat it? / Apples
Can horses eat apples?
Yes, a favorite. Cut into pieces for horses that bolt food.
Core and all is fine in moderation; a whole apple can cause choke in a greedy eater or a horse with bad teeth, so slice it. Two or three a day is plenty; more means sugar and loose manure.
Why
Apples are safe for horses and offer water, fiber, and a natural sweet taste that many horses enjoy. The main concerns are physical rather than toxic: a whole apple can lodge in the throat (choke) in a greedy eater or a horse with worn or sharp teeth. Their sugar content is also worth watching, since too much can upset the gut and loosen manure. Slicing the fruit solves most of the risk.
How much is too much
For a 1,000 lb horse, two or three apples a day is plenty, which is roughly a slice or a small handful cut into wedges. A lot, such as a full bucket or many apples in one sitting, adds enough sugar to cause loose manure and gas. Ponies, miniatures, and metabolic or insulin-resistant horses need far less, often a single thin slice or none at all, and their sugar intake should be discussed with your veterinarian.
Horses
Full-size horses in work or at pasture usually handle a few sliced apples a day without trouble. Offer them as a treat after riding or as a reward for training, not as a replacement for hay or feed. Cut them into wedges and feed from your flat palm so the horse cannot bolt a whole apple. Remove any rotten or moldy pieces, since mold can cause problems.
Ponies and easy keepers
Ponies, miniatures, seniors, and easy keepers are more sensitive to the sugar in apples, which can trigger laminitis or weight gain in prone animals. Keep portions very small, perhaps a thin slice, and skip them entirely for horses with metabolic issues unless your vet approves. Older horses with dental problems also need smaller, thoroughly chopped pieces to reduce choke risk.
Safe alternatives
Carrots, cut lengthwise into thin sticks, give a similar crunch with less sugar. Small pieces of cucumber or zucchini are another low-sugar choice many horses like. Offer any of these in a shallow tub or from your hand, one piece at a time, so the horse chews rather than gulps.
Questions people ask
Can horses eat apple cores and seeds?
The flesh and core are fine in moderation, but apple seeds contain small amounts of compounds that release cyanide when crushed. Remove the seeds and slice the fruit to be safe.
How many apples can a horse have in a day?
Two or three sliced apples is a sensible limit for a full-size horse. Ponies and metabolic horses should have far less, so check with your vet first.
Can apples cause colic in horses?
Large amounts of sugar can upset the gut and contribute to digestive trouble. Whole apples can also cause choke, which is a separate risk. Keep portions small and sliced to avoid both.
Safe for horses means: fine as an occasional treat, prepared as described.
