Horse Supplements: Should you use them for weight gain?

Last updated: April 15, 2023

By: Miles HenryFact Checked

As a horse owner, my neighbor recently asked me if he should be feeding his horses supplements. I explained that while supplements may seem like a good idea to keep your horse well-nourished or prevent health problems, they may not actually need them.

Most horses don’t need supplements. However, they serve an integral role for horses that work hard, are pregnant, and don’t get enough nutrition from hay or grass. Supplements also help skinny or sickly horses as well as those with joint issues.

Not all horses have the same diet or energy requirements, so knowing what your horse needs to be healthy and fit is essential. In this guide, I discuss horse supplements, when they are needed, and how they can benefit your horse’s overall health and well-being.

Here are some of the topics covered:

• Horse supplements for weight gain
• Horse supplements for gut health
• Horse supplements for joints
• Natural horse supplements

Horse supplements for weight gain

To perform optimally and avoid health issues, horses must maintain a healthy weight. Weight gain supplements can help restore balance if a horse begins to lose weight. I have a young horse in training who, despite eating well, remains thin.

Her condition might be genetic, but it’s more likely that she requires additional calories to compensate for the energy expended during training. After conducting blood work, a vet confirmed that she is healthy and fit but agreed that she needs to gain some weight.

To address this, I began offering her more alfalfa and will closely monitor her body condition. If a few weeks of increased alfalfa intake doesn’t result in weight gain, I will consider adding a weight gain supplement to her feed. This should help her achieve the desired weight and ensure she remains in optimal condition.

Here’s what you should know about weight gain supplements for horses:

• Available as liquids or powders, horse supplements for weight gain can be conveniently mixed into feed or administered orally.
• Before introducing any new supplement to your horse’s diet, it’s crucial to consult with a veterinarian for guidance.
• Weight gain supplements for horses typically include high-calorie ingredients such as corn syrup, molasses, soybean oil, and sugar beet pulp, which help provide the extra calories needed for weight gain.
• The majority of high-quality weight gain supplements for horses deliver additional calories in a health-conscious manner.

How do horse supplements for weight gain work?

I’m often asked how horse supplements for weight gain work; are they loaded with sugar, and what else might help get a horse to put on the pounds?

First, it is important to note that weight gain supplements are not meant as a cure-all solution. It would be best to work with your veterinarian, equine nutritionist, or experienced equestrian to formulate a healthy diet for your horse.

Typically you can put on weight on your horse quickly and safely by using supplements. Horse supplements come in several forms, including grain concentrates, protein products like soybean or cottonseed meal, molasses products, beet pulp, and other high-calorie items.

The best horse supplements for weight gain can help a skinny, underweight horse in the following ways:

• Heal the horse’s gut health by adding healthy probiotics and prebiotics. This can help enhance nutrient absorption.
• Provide a horse with minerals and trace minerals.
• Enhance immunity to prevent illnesses
• Reduce stress in injured, sickly horses.

Horse supplements for weight gain can benefit:

What to look for in horse supplements for weight gain?

Horse owners need to know what their supplement contains to ensure they don’t give their horses anything that could cause them harm.

All horse supplements contain active and inactive ingredients. Active ingredients are the beneficial ingredients that do what the supplement claims to do. Inactive supplements are the ones that are added for flavors and tastes.

A good-quality horse weight gain supplement should contain:

• Flaxseed meal or full-energy, full-fat soybeans. These provide healthy proteins and fibers and help build muscles and add weight.
• Vitamin E and selenium – to reduce stress in neglected or sickly horses.
• Probiotics/prebiotics – for improving gut health and balancing intestinal microbiome. They are also beneficial in resisting diseases and improving digestive health.

Caregivers and horse owners often use supplements for joint care, gut/digestive issues, and weight gain for skinny horses. Always consult your vet before feeding any supplement to your horse. Remember, it’s critical to determine why your horse is losing weight to design the best plan for putting weight on your horse.
