As far as horse feed goes, nothing beats fresh grass growing on a healthy pasture. They are healthy, filled with nutrients, and they allow horses to stay active all year round.  Unfortunately, fresh grass isn’t enough. Much like human beings, horses need essential nutrients to survive and grow. Since most pastures are don’t have enough nutrients cater to a horse’s full dietary needs, supplements and feed become a mandatory part of raising a healthy horse. If you are looking to raise a healthy horse, maintaining its weight and muscle tone must matter a great deal to you. In this guide, we will go over some of the best horse feed for weight gain and give you guidelines to help you simplify the decision-making process.

What to Look out for When Buying the Feed for Weight Gain

The Ingredients

While regular hay mixed with legumes will do wonders for your favorite horse, it isn’t as impressive and as nourishing as professionally prepared equine feeds. These feed come prepared with essential minerals and protein. In fact, you’d be surprised at how similar humans and horses’ dietary needs are. Horses need all the vital classes of nutrients to grow and gain weight, and so every great horse feed aimed at increasing the animal’s weight should contain the following:


Even though horses are herbivores, they still need a lot of protein. The best horse feed should contain a reliable source of protein. Some of the common sources include legumes, milk proteins, alfalfa meals, soybeans, linseeds, cottonseeds, safflowers, and sunflowers. Since 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. Feed designed to help horses gain weight should be no different. They should contain most of the accessible sources of quick digesting starches and carbs. Even though the starches and sugars shouldn’t be as prominent as the protein, they should be enough to provide the horse with the necessary energy.

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. Also, everyday foods like tomatoes, berries, and even apples contain antioxidants that can boost performance, increase the shelf life of the feed, and help horses fight off illnesses.

The Age of the Horse

When procuring a proper weight gain feed, it’s important to consider the age of the horse you are buying the feed for. Older horses have a harder time digesting regular food like hay, feed and pasture. If you have an old mare, it’s vital to always opt for high fat, easily soluble feeds that are dedicated to senior equines.
