Buyer’s Guide

We all recognize that to feed our horses healthily and gain weight, the supply of fresh grass must be ample. However, fresh grass alone is not enough to provide a horse a healthy weight. To add weight for horses and tone muscles, a complete diet is necessary, and for this, it is best to seek dietary supplements. Before buying supplements, research the following aspects.

Active Ingredients

Horses require all the essential groups of nutrients to develop and gain weight. A renowned horse weight gain supplement designed to increase the animal’s weight should provide a reliable protein supply as it is responsible for building muscles. Also, to provide necessary energy and enhance performance, the supplement should contain starch and healthy fats.

Supplement Type

Remember that the supplement you finally choose should meet your horse’s specific needs. There are several weight gain supplements with different base ingredients in the market. If you are searching for a supplement whose core function is just to help your horse gain weight, choose calorie-rich supplements specially designed for improvement in weight with increasing muscle mass.

For increased stamina, opt for supplements rich in fats and omega-3 fatty acids as they boost performance by delivering calm calories. Fats enriched supplements are used to maximize the caloric density of horse rations without raising the chances of colic, founder, or stomach discomfort due to the fermentation of starch from grains.

Possible Side Effects

If you have been struggling to get your horse to maintain weight, always look for those supplements causing no or least side effects. Most of the supplements available in the market are known for causing digestive disorders, including ulcers and hyperactivity in horses. So, it’s better to research than to regret.

Quantity

It is ideal to use 4oz of formula a day to increase and maintain the weight. Horses with a higher level of exercise or under stress can use higher supplement levels without additional side effects. For a shiny coat and healthy skin, use only 2oz per day.

Horse’s Age

When you are buying a weight gain supplement, it’s vital to consider the age of the horse you’re purchasing a feed for. Older horses have a hard time swallowing daily food such as hay, grain, and pasture. If you have an old mare, it is essential to always go for high-fat, readily soluble feeds devoted to senior equines.

Frequently Asked Questions

How can I make my horse gain weight quickly?

The digestive system of the horse requires forage for the perfect supply of energy, so avoid the use of too many grain products. If you are unable to adjust the feed product, add a high-fat supplement to your horse’s daily meal. It will help to gain weight with an effective performance rate. Incorporating highly digestible fiber sources is also helpful for encouraging weight gain in horses. Studies have found that this also serves to increase the digestibility of the diet.

What can I feed my older horse to increase its weight?

Minimum 1% of the staple diet of older horses should be in the form of forage, such as hay or pasture for digestive health. Using full commercial feed or weight gain supplements that cater to the caloric needs of senior horses is also ideal. They are fiber-based, mostly alfalfa-based, but contain extremely palatable, dissolvable, and digestible materials along with energy sources of fat, vitamins, and minerals. Concentrate supplements can be essential for senior horses with bad teeth, particularly in the form of a mash.

How long does it take for a horse to gain weight?

Usually, it takes two weeks for a horse to initiate weight gaining along with a balanced feed. The weight gaining duration may vary according to the horse’s age and health condition.

How can I tell if my horse is overweight?

Fat deposits, hard crest, and hampered movements are the most common signs of being overweight. Weak horses have visible ribs. Meanwhile, if your horse’s ribs are not visible and difficult to detect, that might indicate your horse is overweight.

Why do horses lose weight?

In many circumstances, a horse loses weight because it just doesn’t consume enough calories. Other than this, there are several factors (mental and physical) due to which horses lose weight. The main reasons include improper or lack of a nutritious diet, age of the horse, poor water intake, metabolic issues, or any chronic pain, all of which can make a horse underweight.

Conclusion

The concept behind fattening up horses is simple: increase their calorie intake. However, it is not that simple. It takes time and effort to find the right combination of food and supplements. The supplements we’ve included in this list are reliable products.

Most users have had a satisfactory experience with them. If your horse still has trouble gaining weight, don’t hesitate to contact a nutritionist. Gaining weight can be tricky, but the whole experience is worth it. You’ll be happy when your horse trots in the pasture looking strong and healthy.
