What is the 20 Rule for Horses?

When it comes to horse care and management, there are various rules and guidelines that horse owners and caretakers follow to ensure the well-being of these magnificent animals. One such rule that is often mentioned is the “20 Rule for Horses.” In this article, we will delve into the details of what exactly the 20 Rule for Horses entails and how it can benefit your equine companion.

Understanding the 20 Rule for Horses

The 20 Rule for Horses is a principle that revolves around the feeding and nutrition aspect of horse care. It suggests that horses should consume no more than 20% of their body weight in feed per day. This rule is primarily applied to the horse’s forage intake, which includes hay and pasture grazing.

By adhering to the 20 Rule, horse owners can ensure that their horses receive an appropriate amount of forage to maintain a healthy digestive system and overall well-being. It helps prevent issues such as obesity, colic, and other digestive disorders that can arise from overfeeding or underfeeding.

Implementing the 20 Rule for Horses

Now that we understand the basic concept of the 20 Rule for Horses, let’s explore how to implement it effectively:

1. Weighing the Feed

The first step in applying the 20 Rule is to accurately measure and weigh the horse’s feed. This includes hay, pasture, and any additional supplements or concentrates. Use a scale or a weight tape to determine the weight of the feed.

2. Calculating the 20%

Once you have the weight of the feed, calculate 20% of the horse’s body weight. For example, if your horse weighs 1000 pounds, the 20% would be 200 pounds.

3. Dividing the Feed

Divide the calculated 20% by the number of feedings per day. Horses typically require multiple feedings throughout the day to mimic their natural grazing behavior. For instance, if you feed your horse three times a day, divide the 20% by three to determine the appropriate amount of feed per feeding.

4. Monitoring the Horse’s Body Condition

Regularly monitor your horse’s body condition to ensure that they are maintaining a healthy weight. Adjust the feed amount accordingly if you notice any significant weight gain or loss. It’s essential to consult with a veterinarian or equine nutritionist for guidance on adjusting the feed ration.

The Importance of the 20 Rule for Horses

The 20 Rule for Horses holds significant importance in equine nutrition and overall horse care. Here are some key reasons why this rule is crucial:

1. Digestive Health

Horses have a unique digestive system that requires a constant intake of forage to maintain optimal health. By following the 20 Rule, you ensure that your horse’s digestive system functions properly, reducing the risk of colic, ulcers, and other digestive disorders.

2. Weight Management

Obesity is a common issue among horses, which can lead to various health problems, including laminitis and metabolic disorders. The 20 Rule helps horse owners manage their horse’s weight effectively, preventing excessive weight gain and promoting a healthy body condition.

3. Nutritional Balance

Forage is a vital source of essential nutrients for horses, including fiber, vitamins, and minerals. By limiting the amount of feed intake through the 20 Rule, you encourage horses to consume a balanced diet that meets their nutritional requirements.

4. Cost-Effective Feeding

Feeding horses can be a significant expense, especially if they are overfed. The 20 Rule allows horse owners to manage their feed resources efficiently, reducing wastage and saving money in the long run.

Additional Considerations for Horse Feeding

While the 20 Rule for Horses provides a valuable guideline for feeding, there are a few additional considerations to keep in mind:

1. Water Availability

Ensure that your horse has access to clean and fresh water at all times. Water is essential for digestion and overall hydration, supporting the horse’s health and well-being.

2. Quality of Forage

Choose high-quality forage, such as fresh and nutritious hay or well-maintained pasture. Good quality forage provides the necessary nutrients and helps prevent issues like mold or dust-related respiratory problems.

3. Individual Horse Requirements

Every horse is unique, and their nutritional needs may vary based on factors such as age, breed, activity level, and overall health. Consult with an equine nutritionist or veterinarian to determine the specific dietary requirements for your horse.

4. Regular Exercise

Alongside a balanced diet, regular exercise is crucial for maintaining a horse’s overall health and weight. Ensure that your horse receives appropriate exercise and turnout time to support their physical and mental well-being.


The 20 Rule for Horses is a valuable guideline that helps horse owners provide appropriate nutrition and care for their equine companions. By adhering to this rule, you can ensure that your horse receives the right amount of forage, promoting digestive health, weight management, and overall well-being. Remember to consider individual horse requirements, monitor body condition, and consult with professionals for personalized guidance. By following these principles, you can optimize your horse’s health and happiness.
