What Types of Nutrients Does Your Horse Need?

A balanced diet is just as essential to your horse's health as it is to yours. No matter what your horse's age, these nutrients are essential for good health and strong bones and muscles.

Water

Adequate water intake is essential for the absorption of other nutrients, digestion, and temperature regulation. Although you may not be able to force a horse to drink, you can make drinking water more tempting by:

  • Offering fresh water daily rather than topping off buckets and troughs
  • Cleaning buckets and troughs regularly
  • Warming water to 50 degrees in the winter
  • Using bucket heaters or tank de-icers to prevent water from freezing
  • Increasing thirst with salt blocks or electrolyte supplements if your horse doesn't drink enough
  • Soaking forage in water to increase water intake if needed

Adult horses may drink 30 or more liters of water per day, although the amount varies depending on your horse's size and activity level. More water will be needed during periods of heavy exertion, when it's hot or if a mare is lactating.

Protein

Protein keeps your horse's muscles and tissues healthy and its coat sleek and shiny. The nutrient is found in alfalfa, clover, soybean meal, linseed/flaxseed meal, and brewer's grains.

The diet of a mature horse should include 8 to 12 percent protein, while a growing horse needs between 12 to 18 percent, according to the University of Georgia Extension.

Carbohydrates and Fats

Carbohydrates provide energy, play an important role in temperature regulation, and help keep your horse's digestive tract healthy. They're found in forage, feed, and grains. Your horse needs both structural and non-structural carbohydrates. Structural carbohydrates provide your horse with fiber and are obtained from grasses and hay, while non-structural carbohydrates are made up of sugars and starches and are found in grains.

Fat, another source of energy, is readily available in commercial feeds and supplements. Depending on the feed brand, fat quantity can range from 2 to 12 percent.

Without enough carbohydrates and fat, your horse may develop an energy deficiency. Signs of an energy deficiency may include lethargy, weight loss, and decreased growth in young horses.

Ensuring that your horse has the right amount of forage for its weight will keep carbohydrates and fats in balance. Horses should consume 1.5 to 2.5% of their body weight in forage, according to The Horse Magazine.

Vitamins

Feeding your horse fresh forage is a simple way to ensure that it receives all of the vitamins needed for good health. B complex vitamins and vitamins A, E and K are found in forage. Horses can synthesize their own vitamin C and get vitamin D from spending time outdoors in the sunshine. Horses that spend all their time in the barn may benefit from vitamin D supplements.

Minerals

Minerals keep your horse's muscles, bones, nerves, and cells healthy. Most horses receive a sufficient amount of key minerals, including magnesium, calcium, phosphorus, potassium, sulfur, and chloride, from forage and feed. After strenuous activity, your horse may benefit from an electrolyte supplement to replace chloride, sodium, and potassium depleted by sweating. Feeds may not contain enough sodium and chloride. Fortunately, making a salt block readily available can prevent deficiencies.

  • "Kath, thank you so much for being Greyson's vet, your gentle hand, compassion and great skill made all the difference for my buddy."
    --Deirdre Dekking, Portland
  • "Dr. Mertens is a very friendly, knowledgeable equine veterinarian (and a friend to the rest of the farmyard, including the chickens!). Always up to date on the latest in equine health, and even though Mertens Mammals is a small clinic giving you the personable experience, Dr. Mertens also has equipment for more advanced diagnostics and procedures!"
    —Ari Gordon, Boring
  • "I have been a client of Mertens Mammals for 10 years. Kath (Dr. Mertens) is the most kind, thoughtful and caring Vet I have ever had for my animals. I have 3 horses: my Appy "Breeze" who turns 30 this year, my Paint " Rocket " 14 and my other Paint "Fergie " 3 are all under Kath's care. I also had a dog "Cowboy" who I lost to cancer last July. Kath took care of him also. Dr.Mertens came out on Mother's Day about 7 years ago to treat Breeze for a cut above her right eye. After a few weeks of recovery we were happy to not have a huge scar. Kath also spent 2 hours with me 3 years ago when Rocket had a small case of colic. (Thank God). I couldn't ask for a better person to take care of my girls. Kath always calls to check in on the patients. When people ask who I use for my veterinary needs for my horses, I'm always proud to refer them to Mertens Mammals. I am so thankful for an honest and caring Vet. Thank you, Kath!"
    --Michelle Schatz, Portland

Thanks for all you do for both of us—will keep you posted on Sassy.”"
