It’s generally true that horses require more hay in the winter compared to the summer. This is because they need more calories to maintain their body temperature in cold weather. Good-quality grass and legume pastures, along with salt, usually provide enough nutrients for adult horses doing light work or for pregnant mares. However, winter pastures are low in water and protein and may need extra protein and vitamin A supplements.
Why Do Horses Need More Hay in Winter?
Horses need more hay in the winter to maintain their body heat and energy levels. During the colder months, horses burn more calories to stay warm, so they require a higher intake of roughage like hay to meet these increased energy demands.
How Does Cold Weather Affect a Horse’s Dietary Needs?
In cold weather, horses expend more energy to maintain their core body temperature. This process, called thermoregulation, requires additional calories, which are primarily obtained from hay. Hay is digested in the horse’s hindgut through microbial fermentation, which produces heat as a byproduct, helping the horse stay warm.
What Type of Hay is Best for Horses in the Winter?
High-quality legume hays, such as early bloom alfalfa, are excellent for horses, especially those that are growing or lactating. Grass hays like timothy, prairie grass, orchard grass, and bluegrass are also good but may require additional supplementation due to their lower digestible energy and protein content.
How Much Hay Should a Horse Eat Daily in Winter?
The amount of hay a horse needs daily in winter depends on its weight, activity level, and the quality of the hay. A general guideline is that horses should eat 1.5% to 2.5% of their body weight in hay per day. For example, a 1,000-pound horse may need 15 to 25 pounds of hay daily.
Additional Winter Feeding Tips
- Provide constant access to hay: Allowing horses to graze on hay throughout the day and night helps maintain a constant body temperature and supports digestive health.
- Ensure fresh water: Horses need access to fresh, unfrozen water at all times.
- Monitor body condition: Regularly check your horse’s body condition score to ensure they are neither losing nor gaining too much weight.
- Supplement if necessary: If hay quality is poor or the horse is not maintaining weight, consider adding concentrates or other supplements to their diet.

How can I tell if my horse needs more hay?
If your horse is losing weight, appears lethargic, or is constantly shivering, it likely needs more hay. Monitoring their body condition score regularly can help you adjust their hay intake as needed.
Can I feed my horse silage in the winter?
Silage should be avoided as horses and mules are extremely susceptible to botulism and digestive upsets.
Are there any special considerations for feeding senior horses in winter?
Senior horses may have difficulty chewing and digesting hay, so they may require soaked hay or hay cubes. It’s also essential to ensure they maintain a healthy weight and receive adequate nutrition to support their immune system during the winter months.
Understanding your horse’s nutritional needs during the winter is crucial for maintaining their health and well-being. By providing adequate hay and monitoring their condition, you can help your horse stay warm and healthy throughout the cold season.
