How to Feed Watermelon to a Horse?

Horses can eat watermelons but if you are feeding it to them for the first time, there are certain factors that you need to keep in mind. Remember, it is not viable to present them with a huge watermelon to devour under any circumstances. Doing so can be hazardous rather than beneficial to the equine’s health as it has a sensitive digestive system.

So how should you feed your horse watermelons for the first time? Keep reading to know!

  • Wash the rind of the watermelon thoroughly before offering it to your horse. The rind is eatable too and should be free of dust and pesticides for obvious reasons.
  • Introduce the fruit gradually into your pet’s diet even if you are just giving it as an occasional treat. To begin with, offer only one or two watermelon chunks instead of a whole slice.
  • When feeding watermelons to your horse for the first time, make sure to chop the fruit in small pieces, and otherwise the animal is likely to choke on the unfamiliar treat.
  • Refrigerate the watermelon chunks before serving them to your horse during humid weather. This will soothe their thirsty throats while serving as a sweet surprise at the same time.
  • To make your equine’s regular meal more appealing, mix in a couple of watermelon chunks and see how it reacts to the new flavor. Moreover, combining watermelon with oats, coconut oil and wheat can result in tastier treats.
  • Make sure to monitor your horse for any adverse reactions to eating watermelons in the initial phase. In case you do notice some side effects, consult a vet immediately.

Can Horses Eat Watermelon Rind and Seeds?

If you’re all set to discard watermelon seeds and rind before feeding the fruit to your horse, hold on right there. The bitter-tasting rind that apparently holds no worth to you is actually quite advantageous to a horse’s health. Not only is the rind extremely high in fiber, unlike the watermelon flesh which is mainly water, it is also rich in nutrients and minerals.

Regardless, it is important to feed watermelon rind to horses in the right way. First, wash it properly to remove harmful pesticides and then chop it up for the steed to easily chew on. Some horses actually enjoy the crunchy shell of the watermelon more than its fleshy part.

On the contrary, watermelon seeds can be harmful to horses as they contain cyanide just like in the seeds of apples, cherries, and a few other fruits. Hence it is preferable to throw them. However, there is no need to panic if your pet indulges in small amounts of watermelon seeds along with the fruit itself. Just make sure not to feed watermelon seeds to a horse intentionally or in large quantities.

Is Sugar in Watermelon Harmful for Horses?

By now you are probably already content that horses can eat watermelons and gain excellent health benefits. However, the one thing that might still be troubling you is the high sugar content of the juicy treat. Is it really safe for your beloved pet in the long run? Well, the answer to this is yes, absolutely. The fruit is made up of 90% water with roughly only 9 grams of sugar in a cup of diced watermelons. This isn’t a lot considering that most of the foods in a horse’s regular diet like pasture grass and carrots contain a reasonable amount of sugar too.

It’s true that horse food that has high sugar content can cause serious health problems like laminitis and colic, but watermelons are completely safe to consume in moderate quantities. Besides, too much of any food is likely to lead to unpleasant consequences. Nonetheless, despite being a sweet-tasting treat, the sugar level in watermelons is not as high as many of us might think.

When Should You Not Feed Watermelon to Your Horse?

As much as your steed may enjoy the rind and flesh of this refreshing fruit, there are certain dietary and dental conditions in which you should avoid feeding watermelon to your horse. Wondering how and when watermelons can become a dangerous feast for your equine? We’ve enlisted it right here:

Dental Issues

Horses suffering from dental issues are likely to have difficulty in chewing the hard rind of watermelons. Coaxing them to continue eating may eventually cause them to lose all interest in any food that needs to be munched on.

Insulin Resistance

If your horse has any type of insulin resistance, no matter how mild it may be, it is advisable to skip feeding watermelons to the equine due to the sugar content.

Hyperkalemic Periodic Paralysis

Horses with Hyperkalemic Periodic Paralysis should steer clear from foods consisting of potassium. Although the potassium level in watermelons is not too high, Equines with HYPP are prone to suffer from episodes of severe weakness by consuming even a small amount of potassium. Hence it is best to avoid feeding watermelons to horses in such a case.

Nevertheless, even if your horse has no health issues, you should always ensure that it only devours on watermelons occasionally and in limited amounts.

Watermelon Treats for Horses

Instead of simply chopping up the watermelon and offering it to your horse as a boring treat, try to come up with variations to make the food interesting. Here are a few options you can play around with to see which one becomes a hit with your steed.

Frozen Watermelon

Peel off the watermelon rind and freeze the fleshy part after cutting it into bite-sized chunks. You can offer it to your horse in moderation on warmer days as an energizing treat. Your steed will definitely enjoy the crunchiness of frozen food. However, make sure the pieces are small enough to prevent choking.

Watermelon Chunks

Some horses prefer the crunchiness of the watermelon rind more than the juiciness of its flesh, while for others it’s vice versa. Nonetheless, you can discard the seeds and cut the fruit in small pieces to feed your horse both the rind and flesh together for maximum health benefits.

Frozen Blocks

This is perhaps the most fun way to feed watermelons to your horse. All you have to do is peel off the rind and cut up the fruit into pieces. Next, put them in a bucket of water before freezing it. Your horse can playfully lick the frozen treat and eat it as it melts. This one is super refreshing on a hot day.

Bran Mash with Watermelon

Bran Mash is extremely handy when it comes to introducing new foods to a horse’s regular diet. You can mix in small chunks of watermelon along with other fruit and veggies that your equine loves eating and see how receptive it is to the new flavor.
