Horses are magnificent creatures that can bring joy, companionship, and usefulness to our lives. They are majestic animals that require proper care, feeding, and attention to thrive. However, sometimes horses can lose weight, which can be a cause for concern. In this article, we will discuss how to get a horse to gain weight fast, taking into account various factors that may cause weight loss in horses.

Why do Horses Lose Weight?

There are various reasons why horses can lose weight. It could be due to health conditions, poor feeding practices, environmental factors, or age-related factors. Some horses may also be genetically predisposed to weight loss, making it difficult for them to maintain a healthy weight. Nutritional deficiencies are one of the most common reasons for weight loss in horses. Horses require a balanced diet that includes the right amount of protein, carbohydrates, and fats. A lack of essential nutrients can lead to weight loss and other health problems. Inadequate exercise can also contribute to weight loss in horses. Horses that do not receive enough exercise can become overweight or obese, leading to health problems.

How to Tell if a Horse is Underweight?

It is essential to monitor your to ensure that they are healthy and not underweight. One of the easiest ways to determine if a horse is underweight is through Body Condition Scoring (BCS) and the Henneke Scale. This is a method used to evaluate the horse’s body fat and muscle condition by assessing the amount of fat and muscle covering the bones.

The Henneke Scale is the most commonly used scale for BCS in horses. This scale was developed by Dr. Don Henneke, and it uses a 1 to 9 scale to evaluate a horse’s body condition. A horse that scores 1 on the Henneke Scale is extremely emaciated, while a horse that scores 9 is extremely obese.

To perform a BCS, you need to evaluate six different areas of the horse’s body, including the neck, withers, shoulder, ribs, loin, and tailhead. Each area is assigned a score from 1 to 9, and the scores are added up to give a total BCS score. A horse with a total BCS score below 14 is considered underweight.

Causes of Weight Loss in Horses

There are many causes of weight loss, including health conditions, environmental factors, climate, and age-related issues.

Health Conditions

One of the most common causes of weight loss in horses is underlying health conditions. Horses that are suffering from digestive disorders, such as colic, diarrhea, or gastric ulcers, may experience weight loss due to poor nutrient absorption. Horses with metabolic disorders, such as Cushing’s disease or insulin resistance, may also experience weight loss as a result of their condition.


Another factor that can contribute to weight loss in horses is the environment. Horses that are kept in poor living conditions, such as overcrowded or unsanitary stables, may experience stress and weight loss. Horses that are exposed to extreme temperatures or weather conditions may also lose weight as their bodies struggle to regulate their body temperature.


Climate can also play a role in horse weight loss. In colder climates, horses may require more feed to maintain their body weight, as their bodies require more energy to keep warm. Horses in hot climates may experience dehydration and weight loss due to excessive sweating and water loss.


As horses age, they may experience weight loss due to a decrease in their digestive efficiency. Older horses may also have dental issues that make it difficult for them to chew and digest their feed properly. Additionally, older horses may experience muscle wasting and a loss of body condition due to decreased activity levels.

Possible Solutions

If you suspect that your horse is underweight, there are several steps you can take to help them gain weight.

  • Evaluate Your Horse’s Diet: The first step in helping your horse gain weight is to evaluate its diet. Make sure that they are receiving enough high-quality hay or pasture, as well as a balanced grain or concentrate feed. Horses that are underweight may require additional calories, so consider adding a high-fat feed to their diet, such as rice bran or stabilized rice bran. If your horse is on medication that might be contributing to weight loss, discuss alternate options with your veterinarian.
  • Increase Feed Gradually: It’s essential to increase feed gradually to prevent digestive upset. Adding too much feed at once can lead to colic, which can be life-threatening. Start by increasing the amount of hay or pasture, then gradually introduce a balanced grain or concentrate feed. Consider feeding smaller meals throughout the day instead of one large meal.
  • Offer Supplements: Supplements can help boost your horse’s nutrient intake, which can be especially beneficial for horses that have underlying health conditions. Consider adding a vitamin and mineral supplement or a digestive aid to your horse’s feed.
  • Dental Checkup: If your horse is having difficulty chewing their food, a dental checkup may be necessary. Horses require regular dental care to ensure that their teeth are in good condition, which can affect their ability to eat and digest their food properly.
  • Consult with a Veterinarian: If your horse’s weight loss is due to an underlying health condition, it’s essential to consult with a veterinarian. They can perform a thorough evaluation of your horse’s health and provide recommendations for treatment.
  • Manage Stress: Stress can have a significant impact on your horse’s health and well-being. Ensure that your horse has a safe and comfortable living environment and that their social and emotional needs are being met. Consider providing them with toys or activities to help keep them mentally stimulated and reduce stress levels.
  • Adjust Feeding Schedule: Adjusting your horse’s feeding schedule can also be beneficial. Horses that are underweight may benefit from more frequent feedings throughout the day, as this can help increase their calorie intake. Consider offering hay or pasture throughout the day, and offering smaller meals of concentrate feed.
  • Regular exercise: Regular exercise can help horses maintain their weight and promote muscle development. However, it is important to increase exercise gradually to avoid injury or further weight loss.


Maintaining a healthy weight is essential for a horse’s overall health and well-being. Horse owners should monitor their horse’s weight regularly and take steps to prevent weight loss or promote weight gain if necessary. Proper nutrition, adequate exercise, and a stress-free environment are crucial to helping horses gain weight quickly. In cases where weight loss is due to underlying health conditions, prompt veterinary attention is essential. By taking these steps, horse owners can help ensure that their horses remain healthy and happy.
