Should I increase my horse’s hay intake during winter?

It’s generally a good idea to increase your horse’s hay intake during the winter to help them maintain body weight and stay warm. Hay provides essential fiber that generates heat as it’s digested, helping your horse regulate its body temperature in colder weather. However, the exact amount depends on various factors, including your horse’s weight, activity level, and the quality of the hay.

Why Increase Hay Intake in Winter?

During winter, horses require more energy to maintain their body temperature. The primary reason to increase hay intake is to provide additional calories to meet these increased energy demands. The digestion of fiber-rich hay generates heat internally, helping horses stay warm, acting as a natural heating system. Additionally, winter pastures often offer limited or no grazing, making hay the primary forage source.

How Much More Hay Should I Feed?

The amount of hay you should increase depends on several factors:

• Horse’s Weight: Larger horses need more hay than smaller ones.
• Activity Level: Horses in heavy work require more calories.
• Hay Quality: Nutrient-poor hay requires larger quantities.
• Weather Conditions: Colder temperatures increase energy needs.

As a general guideline, horses should consume 1.5% to 2.5% of their body weight in forage daily. In winter, aim for the higher end of this range, adjusting based on your horse’s condition.

What Type of Hay is Best for Winter Feeding?

High-quality legume hays, such as early bloom alfalfa, are preferred for horses, especially those that are growing or lactating. Grass hays, such as timothy, prairie grass, orchard grass, and bluegrass, were preferred by early horsemen, especially for race horses, because they were usually free from mold and dust and tended to slow down the rate of passage through the intestinal tract.

Other Considerations for Winter Horse Care

• Water: Ensure access to unfrozen water, as dehydration can lead to colic.
• Shelter: Provide a windbreak or shelter to reduce heat loss.
• Blanketing: Use blankets for horses that are clipped, old, or have difficulty maintaining weight.
• Body Condition: Regularly assess your horse’s body condition to adjust feed as needed.

What are the risks of feeding moldy or dusty hay?

Moldy or dusty feeds should be avoided because horses are extremely susceptible to forage poisoning and respiratory complications.

How often should I feed my horse during the winter?

Horses benefit from frequent small meals. Divide the daily hay ration into multiple feedings to mimic natural grazing behavior.

What are signs my horse needs more hay?

Signs include weight loss, a dull coat, and increased shivering. Monitor your horse closely and adjust the hay ration accordingly.

Increasing your horse’s hay intake during winter is a crucial part of their care. By understanding your horse’s individual needs and providing adequate forage, you can help them stay warm and healthy throughout the winter months.
