Blanketing Horses in Cold Climates

A popular question always comes up when the temperature drops – should I blanket my horse in cold climates? The horse’s hair coat is an excellent insulator and works by trapping and warming air. A healthy horse with a thick, dry and clean hair coat can retain enough heat and be comfortable outside in cold climates.

A horse will continue to develop a natural winter coat until December 22 (Winter Solstice), as the days become shorter and temperatures become colder. Horses begin to lose their winter coat (and start forming their summer coat) as the days become longer (starting December 23) and temperatures start to warm (slowly). Blanketing before December 22 will decrease a horse’s natural winter coat.

Horses can acclimate to cold temperatures and often prefer the outdoors. However, blanketing a horse is necessary to reduce the effects of cold or inclement weather when:

  1. No shelter is available during turnout periods and the temperatures or wind chill drop below 5 F
  2. There is a chance the horse will become wet (e.g. rain, ice, and/or freezing rain, usually not a problem with snow)
  3. The horse has had its winter coat clipped
  4. The horse is very young or very old
  5. The horse isn’t acclimated to the cold
  6. The horse has a body condition score of 3 or less.

If a horse is blanketed, it is critical that the blanket fits properly. Poorly fitted blankets can cause sores and rub marks, especially along the straps. Remove the blanket daily, inspect it for damage, the horse for rub marks, and re-position it. Make sure the blanket stays dry and never put a blanket on a wet horse, wait until the horse is dry before blanketing.

Horses Winter Water Needs: Ask the Expert

Horses Winter Water NeedsQuestion: I’ve heard that horses need more water in the winter, is that true?

Answer:  During the summer months, pasture contains about 80% moisture and can contribute to your horse’s water requirement if grazing.

In contrast, hay should contain less than 15% moisture, increasing your horse’s need for water during the winter months or when fed a primarily hay diet.

If your horse doesn’t drink enough water during cold weather they may eat less and be more prone to impaction colic and more susceptible to cold weather.

Most 1,000-pound adult, idle horses need at least 10 to 12 gallons of water daily and water is most readily consumed when kept between 45 and 65°F.

Horse Body Condition. Beware of Loss of Body Condition in Cold Weather

Horses running through snow representing Horse Body Condition. Beware of Loss of Body Condition in Cold WeatherCold weather, especially temperatures below freezing and cold rains, necessitates owners paying close attention to their horses. It is important to ensure that the horses maintain weight throughout the winter months.

Monitoring and Maintaining Body Condition Score

First, make certain the horses are at least a body condition score of 5 or 6. This means that the horses are carrying some fat cover over their ribs.  Body condition should be monitored by physical examination at least monthly as long hair can hide weight loss.  This is particularly important for older horses.  The horses should also be kept up to date on dental care and overall health care, including appropriate deworming.  It is a good idea to let horses go barefoot with proper hoof care during the winter.

Water Availability and Temperature Considerations

Adequate water, above 40 degrees Fahrenheit, should be available at all times.  If water sources freeze, the ice should be broken at least twice per day.  Owners should NOT rely on horses eating snow for their water supply.  A 1200-pound horse will require 12-15 gallons of water per day during cold weather.  Having inadequate water available or water that is too cold for horses to drink comfortably may contribute to impaction colic.  A horse that does not have adequate water available will also decrease feed intake. This may lead to loss of body condition.  Salt should be available free choice, preferably loose salt rather than a salt block as horses may not lick a cold salt block.

Shelter from Cold Rains and Wind

Provide shelter from cold rains and wind.  Horses remain remarkably comfortable in cold weather if they are dry and have shelter from the wind.  Cold rains mat down the hair coat, reducing the insulation value of the hair and causing the horses to lose body heat. State regulations may dictate shelter requirements.

Adjusting Feed to Meet Increased Energy Requirements

Fourth, feed more!  A horse’s digestible energy requirement increases for each degree below the thermal neutral zone.  Wind chill increases the energy requirement also.  Hay or high fiber products produce more heat during digestion than do grains, so adding extra good quality roughage to the diet is a good option.  Grain intake can also be adjusted to maintain the desired body condition, but needs to be adjusted gradually.

Calculating Energy Requirements for Cold Weather

A 1200 lb. horse at maintenance requires about 17.7 Mcal (17,700 Calories) of DE for maintenance. Each degree C below Lower Critical Temperature (Anywhere from 5 degrees C or 40 degrees F down, depending on what the horse is used to.) increases DE requirement about 2.5%. (NRC, 6th Edition, page 10-11.)  Converting to Fahrenheit, each degree drop requires about 1.375%, so if the temperature drops from 10 degrees F to 0 degrees F, the DE requirement may increase 13.75% to 20.13 Mcal or 20,130 Calories.  This increase of 2430 Calories would require an additional 2.8 pounds of alfalfa grass hay to maintain body condition.  If the horse does NOT get the additional DE, the horse could lose a little over a quarter of a lb. per day.  If we have 3 months of cold weather, it is very easy for a horse to drop a full body condition score.  Shorter periods of extreme cold may cause more rapid loss of weight.

Proper winter care will help assure that your horse is ready for spring!

When to Blanket a Horse: Ask the Expert

As the winter season approaches, the decision to blanket a horse can be a topic of confusion and debate. While some horses can thrive without blankets, understanding when it is necessary to provide extra protection and warmth is crucial. In this article, we address common questions and provide expert advice on when to blanket your horse during the winter months.

Question and Answer: Understanding Winter Blanketing

The Confusion and Personal Preferences

Question: “I’m confused about blanketing my horse during winter. Growing up, our horses were happily housed outside without blankets, as they had access to shelter. However, now that I’m boarding my horse, everyone at the barn blankets their horses and thinks I’m crazy not to. Can you provide some advice on blanketing during the winter?”

Answer: Blanketing practices vary based on individual circumstances, including show schedules and personal preferences of horse owners. While some horses may not require blankets, there are situations when blanketing becomes necessary to minimize the effects of cold or inclement weather.

When to Blanket: Key Considerations

To determine if blanketing is necessary, consider the following factors:

1. Lack of Shelter and Extreme Cold

Blanketing is recommended when there is no available shelter during turnout periods, and temperatures drop below 5°F, or the wind chill is below 5°F. The blanket provides additional insulation and protection against severe weather conditions.

2. Wet Weather Conditions

Blankets are beneficial if there is a chance the horse will become wet due to rain, ice, or freezing rain during cold weather. Wet hair reduces the horse’s ability to retain body heat, increasing the risk of hypothermia.

3. Clipped Horses

Horses that have had their winter coat clipped for specific purposes, such as showing or intense exercise, may require blankets to compensate for the lack of natural insulation provided by their coat.

4. Young or Elderly Horses

Very young or elderly horses have a harder time regulating their body temperature and may benefit from blankets to stay comfortable and prevent temperature-related health issues.

5. Horses Recently Relocated from Different Climates

If a horse has been recently moved from a southern climate to an area with colder winters, they may not have had time to acclimate to the lower temperatures. Blanketing can provide them with additional warmth until they adjust.

6. Poor Body Condition

Horses with a body condition score of 3 or less (on a scale of 1-9) may struggle to maintain their body heat and may benefit from the added insulation provided by blankets.

Understanding Winter Coat Development

Natural Winter Coat Growth and Shedding

Horses naturally develop a winter coat until the Winter Solstice (around December 22), as days become shorter. Afterward, they start shedding their winter coat and forming their summer coat as the days gradually lengthen. Blanketing before December 22 may decrease a horse’s natural winter coat growth.

Properly assessing when to blanket a horse during winter requires considering factors such as shelter availability, weather conditions, coat condition, age, and body condition score. While some horses can withstand the cold without blankets, others benefit from the added warmth and protection. Observing your horse’s behavior, consulting with professionals, and considering individual circumstances will help you make informed decisions regarding winter blanketing.
