8 Best Pain Reliever Products for Horses

Nothing is better than fresh grass growing on a healthy pasture as a horse feeds. Unfortunately, it doesn’t have enough nutrients to keep the horses healthy. Yet, they keep the horses active and alive all year round. Like others, horses need help in getting essentials to survive and grow healthier. Since most pasture doesn’t have enough, horses need supplements added to their feeds. In this guide, we will go over on different horses’ weight gain supplements. We will need to understand what the underlying problem is. Then, develop a plan to restore the horse’s physique.

What Causes Horses’ Weight Loss

A variety of factors involved in causing horses to lose weight. While age and concurrent diseases play a role, the owner’s ignorance matters. Also, some horses lose weight because his caloric needs are not met. They are burning more energy compared to what they’re consuming. There are many underlying issues that cause weight loss. This includes the following:


There are many diseases that can lead to weight loss. Most have other obvious signs such as diarrhea, colic, and fever.

In some cases, signs of illnesses are subtle or nonexistent. Possible chronic pain and heavy parasite load may also affect your horse’s weight. Besides, the pain of arthritis can interfere with a horse’s feed intake. The pain prevents him from walking to hay feeders, or his wounds aren’t covered enough.

Dental issues

Problems with a horse’s teeth can affect its ability to eat. Uneven wear can cause hooks, waves, and other malformations that inhibit chewing. A cracked or infected tooth is painful enough to discourage a horse from chewing its food.

Social problems

Horses that live in stable herds develop distinct social hierarchies. Those at the bottom of the pecking order—often the very young, the aging. 


There are horses that spend their time running back and forth. Some also keep on nickering to other horses. Also, there are horses who ask for attention from their handlers by not eating at all. And there’s the picky eater, who pushes his pellets around, picks out the choicest bits of hay, and poops on the rest.

Environmental conditions

Horses burn more calories to stay warm in cold weather. Extreme heat can also cause them to lose interest in food.

What to Consider When Buying the Supplements


When procuring a proper weight gain feed, it’s important to consider the age of the horse. Old horses have more difficulty in digesting regular foods, such as hay, feed, and pasture. If you have an old mare, it’s vital to always opt for high fat, soluble feeds dedicated to senior equines.


Regular hay mixed with legumes will do wonders for your favorite horse. Yet it isn’t nourishing as it may be. The feeds should contain essential minerals and protein. It needs all the vital nutrients for growth and weight gain. Horse feed aims at increasing the animal’s weight, thus it should contain the following:


Even though horses are herbivores, they still need a lot of protein. The best horse feed should include an efficient protein source. This includes legumes, milk proteins, alfalfa meals, soybeans, linseeds, cottonseeds, safflowers, and sunflowers. Protein is essential for growth. It should make up a bulk of the nutrients in a horse feed designed for weight gain.

Starch or Carbohydrates

The best feed for performance uses a mixture of oats, barley, hay, and beet pulp. A feed designed to help horses gain weight isn’t different. It should contain the most accessible sources of quick digesting starches and carbs. Although they aren’t as prominent as the protein, it should be enough energy booster.

Fats, Vitamins, and Minerals

Healthy grains and fruits are an equestrian’s go-to source for minerals and vitamins. They are an essential source of energy, and they provide protection for the immune system. Foods like tomatoes, berries, and even apples contain antioxidants. Antioxidants boost performance and It increases the shelf life of the feed. It helps horses fight off illnesses.

Fastest Weight Gain Methods

Hay and Pasture

Maximizing hay is the most significant way of helping a horse gain weight. Quality is paramount. Good quality hay provides a free option for gaining weight. If a horse feeds on grass and hay, try adding alfalfa up to a 50/50 blend of grass. 

Other Feeds

Soaked beet pulp is a great choice for feeding horses the extra calories needed to gain weight.

Unmolassed beet pulp is low in sugar content and a good addition to a horse’s diet for weight gain.

Wheat bran considers being a source of fiber. It contains around the same amount of fiber as oats. Wheat bran is a good source of energy since it is abundant in indigestible fiber and starch. Also, it contains a large quantity of phosphorus. This can disrupt the calcium and phosphorus ratio in the diet. On the flip side, wheat bran complements a diet high in alfalfa hay because of the calcium in the alfalfa. Rice bran is often used as a higher fat option to help.

Grains, such as corn and oats, have the higher calorie content. They also have much higher omega-6 fatty acids and oxidation levels. 


Oils are great for weight gain as they contain pure fat. Fat offers a much higher amount of calories per gram. Approximately 2.25 times the amount of calories compared to protein or carbohydrates.


A good pre- and probiotics can be very helpful for weight gain. A supplement for a balanced diet will most likely be necessary. 

It is important to make any changes to the horse’s diet little by little. At least about 7-10 days, to allow the digestive tract to acclimate.

All horses should have access to clean water and a plain, white salt block or loose salt. Also, your choice of hay is always a great way to start a horse on a weight gain plan. If possible add a feeding schedule at night or for lunch. Separate the thin horse from the large ones, so that he can feed without fighting for more food.
