Health Benefits

  • Protein: Like humans, horses need proteins for a number of reasons. First, they are responsible for the body’s immunity, regulation of body metabolism, and even transportation of nutrients throughout the bloodstream. Peanut butter has an estimated 7 grams of protein that will go a long way in serving these roles.
  • Vitamin B3: Peanut butter also contains essential vitamin B3, which helps a horse’s nervous system to function smoothly.
  • Vitamin B6: Your horse needs adequate hemoglobin to function effectively. Vitamin B6 that is available in peanut butter will see to that. Besides, it will also improve food digestion.
  • Phosphorus: From time to time, your horse’s cells and other body tissues will require some repair after they are worn out. There are around 107 mg of phosphorous in peanut butter for that purpose.
  • Zinc: Zinc is essential to maintain your horse’s hooves. It will also be necessary for the development of their bones.
  • Magnesium: The absence of magnesium in your horse’s body can be fatal to their health. For instance, they can easily become tired and nervous. Peanut butter has around 57 mg of this vital mineral. Your horse will need it.

The Right Way of Feeding Peanut Butter

If you are a new pet owner, you might be confused about the right amount of peanut butter to feed your horse.

Feed moderately (two spoonsful maximum) and not more than once a week. It is advisable to keep the quantity as low as possible. Follow these two feeding rules to make sure it’s safe for consumption.

When to Avoid Peanut Butter for Your Horse

In some cases, you should consider not feeding your horse peanut butter. For example, consider the following:

Side Effects of Peanut Butter

In most cases, horses can comfortably consume foods that have allergens like nuts without any allergic reactions. However, there are rare cases where their systems just can’t take it. If yours is one such horse, you might want to be very careful before feeding them peanut butter.

Be observant and note how it behaves.

Risk Factors

There are health benefits that can be gained from horses eating peanut butter. But there are also risks associated with too much consumption of peanut butter.

High Calories

As noted earlier in this article, peanut butter contains a high number of calories per serving (about 188 kcal in 2 tbsp). This is high even for human beings. What is the implication of this?

Too many calories are never great. They pose a risk to the animal’s health and can even result in obesity and becoming overweight.


Peanut butter contains a high number of sugars. These may cause a spike in the blood sugar level of your horse. If this continues gradually, you will soon be looking at an obese horse, among other lifestyle diseases.

Peanut butter can be helpful to your pet’s nutritional needs if appropriately given.

What Should You Use to Replace Peanut Butter?

While horses shouldn’t miss out on satisfying their sweet tooth, peanut butter is not all healthy, and you might want to consider other options.

Here’s a list of other options you could be overlooking:
  • Apples
  • Carrots
  • Strawberries
  • Bananas
  • Pumpkin
  • Celery

You will be surprised how much your horse will love these food options. They have their health benefits too, so you might want to try them out.

We can conclude that horses can safely consume peanut butter in limited amounts. Please remember that it should be a seasonal ‘treat.’ It is crucial to limit their consumption to 1 to 2 tablespoons. Don’t even try experimenting with this for horses with allergic reactions or metabolic syndrome.

Generally, a horse’s digestive system is not adequately adapted to break down processed foods. Peanut butter is not an exemption. As such, feed them peanut butter moderately to avoid health issues. Always consult your vet whenever you are unsure because it’s better to be safe than sorry.
