Can Horses Eat Sweet Potatoes?

You can feed sweet potatoes to horses as part of their feed or as a treat

I don’t know about you but I like to feed my horse different treats, I always think that if I’m feeding him the same thing all the time it’s not really a treat. Over the years I thought I’d tried everything but when somebody recently suggested I tried feeding sweet potatoes I realized I hadn’t at all. With this in mind, I decided to do a little research, after all, I didn’t want to go and feed my horse something that would harm him. While I knew normal potatoes are toxic I was surprised with what I found about sweet potatoes.

Can horses eat sweet potatoes? Sweet potatoes (or yams as they’re sometimes called) are perfectly safe for horses to eat and are also a great source of vitamins (Vitamins A, C, and E in particular). On top of that, they’re also able to heal gastric ulcers.

If you’re worried about feeding sweet potatoes to your horse because you’ve heard that they’re a member of the nightshade family don’t worry, while normal potatoes are part of the family, sweet potatoes aren’t from the same family at all. They’re actually from the morning glory family (nothing to do with the Oasis album ‘What’s The Story Morning Glory’), that also contain yams and water spinach, and are not only safe for your horse to eat but can also have a number of health benefits, not least helping to treat gastric ulcersOpens in a new tab..

Are sweet potatoes healthy for horses?

The term ’superfood’ is one of those things that’s banded around a lot these days, often without cause, but when it comes to sweet potato there’s a good reason why they should wear their superfood badge with pride. Yes they do contain sugar (at around 4.2g per 100g of sweet potato it’s less than you’d find in a carrot), but the other nutrients certainly make up for the sugar, and anyway, horses need a certain amount of sugar in their diet.

On top of protein and dietary fiber sweet potatoes also have a very good selection of vitamins and minerals:

  • Vitamin A – As well as boosting your horse’s immune system and strengthening his bones, Vitamin A can also help to reduce the risk of cataractsOpens in a new tab..
  • Vitamin C – Like Vitamin A, Vitamin C can help to improve your horse’s immune system but it can also help to heal wounds and keep your horse’s teeth, bones, and cartilage healthy.
  • Vitamin B5 – Part of the B complex vitamin group, Vitamin B5 can help to keep your horse’s coat in good condition. It also works to aid digestion, especially in the digestive tract.
  • Vitamin B6 – Another B complex vitamin, it’s known for its ability to reduce the symptoms of some forms of arthritis as well as keeping the eyes healthy. If your horse suffers from depression then Vitamin B6 can help with this.
  • Vitamin E – Known for its ability to fight infection, Vitamin E also works to maintain healthy skin, eyes, and even a healthy coat.
  • Potassium – You might not realize it but potassium is actually one of the most important minerals in the body, it works to keep a horse’s muscles working properly and will also help to reduce tiredness after exercise.
  • Manganese – Not only does manganese help to keep your horse’s bones strong and healthy but it can also reduce inflammation. In my opinion, though the biggest role that manganese plays is in the regulation of blood sugar, this means that it may be good for horses that suffer from conditions such as Equine Cushing’s DiseaseOpens in a new tab.

As you can see sweet potatoes are very healthy for horses, but like all treats, they should be fed in moderation and as part of a proper and balanced diet.

Can horses eat sweet potato peelings?

Every part of the sweet potato is safe for horses to eat but while some horses won’t like the taste of the roots or leaves most will love the peel (or skin) which is a good thing because the peel is actually healthier than the flesh. While the whole sweet potato is packed full of goodness, the peel itself actually contains almost double the number of antioxidants than the vegetable which means that they’re not only a tasty treat but a healthyOpens in a new tab. one too.

As well as bursting with antioxidants the peel is a great source of dietary fiber so will help to keep your horse’s digestive system in tip-top condition which can also help to prevent colic.

When feeding sweet potatoes to horses its better to cut them into slices or cubes

Should horses eat cooked or raw sweet potatoes?

Most people will say that you should feed sweet potatoes raw, and while that’s obviously the easiest thing to do it doesn’t mean that you can’t cook them before feeding them to your horse, it’s down to your horse’s personal preference really – both are just as good.

Personally, I prefer to feed them raw because I can cut them into slices or wedges and then either leave them in the feed room or carry them in my pocket while out riding.

How do sweet potatoes treat stomach ulcers?

If you search the internet for the best way to naturally treat ulcers you’ll probably find a list of herbal remedies that really do work but what might surprise you is that many of those remedies can be found in sweet potatoes which is why feeding just one sweet potato a day can completely heal many ulcers (they can also help with a number of other gut and bowel issues too).

  • Methanol – Found in the roots of sweet potatoes it’s known to help protect gastric tissue against peptic ulcers and those caused by prolonged use of NSAIDs (non-steroid anti-inflammatory drugs).
  • Flour – Again found in the roots of the vegetable, it’s known to suppress gastric ulcers by reducing the swelling around the tissue as well as reducing gastric wrinkles.
  • Vitamin A – As well as helping to prevent ulcers in the first place, Vitamin A also works to shrink the ulcer and thus speeding up the healing time.
  • Vitamin C – While we all know that Vitamin C can help to prevent colds, it’s not so widely known that it also works to repair wounds, including peptic ulcers.
  • Beta-carotene – This won’t prevent ulcers but it will help to reduce the severity of symptoms as well as boost the effectiveness of any prescribed treatment.

Sweet potatoes are so good at treating ulcers that some veterinarians may even prescribe them, even if only as a way of boosting conventional medicines such as omeprazole. 

Can sweet potatoes change the color of my horse’s coat?

Sweet potatoes can alter the color of a horses coat

While nobody would claim that feeding sweet potatoes changed their horse’s coat color some owners have reported that it has altered the shade of their coat. Now I know this may sound like an old wive’s tale but there is actually some evidence that, depending on your horse’s coat color, feeding them a sweet potato every day will darken the color. This is more common in horses that are brown, bay, chestnut, and sorrel, or at least would be if they didn’t have any dilution genesOpens in a new tab..

The reason for this is that sweet potatoes are high in copper (out of all vegetables they actually contain the second-highest levels of copper), a mineral that’s known to not only help the condition of the skin but is also used in the production of melanin. It’s the melanin that gives the skin pigment its color and tone, so when this is boosted with a regular supply of extra copper it stands to reason that your horse’s coat will darken slightly.

Don’t worry if you don’t like your horse’s new coat color though, it’ll return to normal pretty quickly after you stop feeding sweet potatoes every day.
