Pasture and Hay for Horses

Regarding the health and well-being of horses, one crucial aspect that cannot be overlooked is their diet. Providing horses with a balanced and nutritious diet is essential for their overall health, especially regarding their primary forage sources – pasture and hay. In this article, we will delve into pasture and hay for horses, exploring their benefits and differences and how to optimize their usage to ensure the best possible nutrition for our equine friends.

The Importance of Forage for Horses

Before we delve into specific types of forage, let’s understand why forage, such as pasture and hay, is crucial for horses. Horses are herbivores whose digestive systems have evolved to process plant material primarily. Natural grazing behavior allows horses to obtain the nutrients they need by consuming grasses, legumes, and other forage.

Forage is not only a vital source of nutrition but also plays a significant role in horses’ overall health and well-being. It aids in maintaining healthy gut function, provides fiber for proper digestion, and supports dental health by promoting natural chewing and grinding, helping to prevent dental issues such as overgrown teeth.

The Benefits of Pasture for Horses

Pasture grazing is an ideal and natural way to ensure horses receive the necessary nutrients. Here are some of the key benefits of providing pasture for horses:

  1. Abundant Nutrition: Pasture contains a variety of grasses, herbs, and legumes that offer a diverse range of essential nutrients and minerals that contribute to a balanced diet for horses.
  2. Exercise and Mental Stimulation: Grazing on pasture allows horses to move freely, encouraging exercise and providing mental stimulation. Grazing also simulates their natural feeding behavior, keeping them happy and content.
  3. Vitamin D Production: Sunlight is necessary for horses to produce vitamin D, and grazing on pasture exposes them to natural sunlight, fulfilling their vitamin D requirements.
  4. Reduced Boredom and Stall Vices: Horses with access to pasture are less likely to develop boredom-related behaviors, such as cribbing or wood chewing, as they can graze and explore.

The Role of Hay in a Horse’s Diet

While pasture grazing is an excellent way to meet a horse’s forage requirements, it might only sometimes be available or sufficient. In such cases, hay is the go-to alternative. Hay is dried and preserved forage that can be stored and fed to horses when pasture grazing is limited or impractical.

Hay plays a crucial role in a horse’s diet and can be used to supplement pasture grazing. Here are a few reasons why the grass is beneficial:

  1. Consistent Nutrition: Good quality hay provides consistent nutrition, allowing horse owners to ensure their horses receive adequate nourishment even when pasture grazing is limited.
  2. Controlled Diet: Using hay allows horse owners to control their horses’ diet better by regulating intake and monitoring nutrition levels.
  3. Year-Round Availability: Unlike pasture, hay can be stored and used throughout the year, ensuring a steady supply of forage, regardless of the season or weather conditions.
  4. Additional Roughage: Hay provides additional roughage, promoting proper digestion and gut health in horses.

Choosing the Right Pasture and Hay for Horses

Now that we understand the importance of pasture and hay in a horse’s diet, it is crucial to focus on providing suitable types and quality forage. Factors to consider when choosing pasture and hay include:

  • Type of Grass: Different types of grasses have varying nutritional profiles. Consult a local expert to determine the best grass species suitable for your area and your horse’s needs.
  • Mixture of Legumes: Legumes, such as clover or alfalfa, can be highly nutritious and provide additional protein. Including a legume mixture in pasture or hay can enhance the overall diet.
  • Quality of Hay: Hay quality is crucial, as poor quality hay can lack nutrition and may even contain harmful substances. Look for grass free from mold, dust, or weeds with a fresh aroma.
  • Proper Storage: To maintain hay quality, it must be stored in a clean, dry area to prevent mold, moisture, and contamination.

Supplementary Feeding when Pasture or Hay is Limited

In certain situations, such as during winter or when pasture is sparse, horses may require additional feed to meet their nutritional needs. You must consult a veterinarian or equine nutritionist for the best supplementary feeds.

Grain-based concentrates, such as pellets or grains, can supplement the diet temporarily. These should be introduced gradually and fed in limited quantities to avoid digestive issues. Always follow the recommendations provided by professionals for the specific needs of your horse.

Pasture and Hay Management

Managing pasture and hay is crucial to ensure horses receive optimal nutrition and prevent potential health issues. Here are some essential tips:

  1. Rotational Grazing: Rotational grazing allows pastures to rest, preventing overgrazing and maintaining healthy grass growth.
  2. Avoid Grazing when the Ground is Wet: Grazing on wet ground can cause damage to the grassroots, leading to poor pasture quality. Restrict access to pasture during excessively wet conditions.
  3. Regular Fertilization: Fertilizing pastures can ensure they have the nutrients for healthy growth and provide adequate nutrition for horses.
  4. Regular Hay Analysis: Analyzing hay regularly helps determine its nutritional content and any deficiencies, allowing you to adjust your horse’s diet.


Pasture and hay are integral to a horse’s diet, providing essential nutrition, exercise, and mental stimulation. By understanding the benefits of field and grass, selecting suitable forage types, and managing them effectively, horse owners can ensure their equine companions receive the best nutrition and overall well-being.
