Horses Require Extra Attention when Temperatures Plummet
With freezing temperatures comes the need for extra care and attention for horses and other equids.
The growing season some parts of the nation had last year produced overly stemmy or fibrous hay with a lower digestibility. As a result, making certain that horses are supplemented with grain when fed lower quality hay will help them maintain body weight and condition, a key factor in withstanding cold temperatures.
Constant access to clean, fresh water at 35 to 50°F is an absolute necessity to keeping horses healthy. This can be achieved via heated tanks or buckets, or by filling a tank, letting it freeze, cutting an access hole in the frozen surface, and then always filling the tank to below the level of the hole from that point on. This provides a self-insulating function and will typically keep the water below from freezing. Regardless of the method you choose, it’s important to check tanks frequently to ensure your horse’s water remains free of ice.
Additional ways to keep horses comfortable in cold weather include making sure they have access to shelter. A well-bedded, three-sided shed facing south or east will typically provide adequate protection from wind and snow, as can appropriate bluffs or treed areas.
When the temperatures get colder, mature horses will not typically move around much in an effort to conserve energy. Making an attempt to keep hay, shelter, and water fairly close together can limit the energy expenditure required, thus conserving body condition.
And, finally, keeping horses at a body condition score of 5 or 6 (on a 9-point scale) will help prevent surprises when horses shed their winter hair in the spring, and improve conception rates for those choosing to breed.
I walked outside to sit on my porch and enjoy the evening, when I realized that the time is fast approaching where I can not longer do so without bundling up first. I decided it was time to get ready for the winter months ahead especially for my equine friends.
I have included articles, lists, resources, etc to help you make sure you and your horse are ready for the dropping temperatures!
Preparing Your Horse for Winter
By: Dr. Lydia Gray
Hot chocolate, mittens and roaring fires keep us warm on cold winter nights. But what about horses? What can you do to help them through the bitter cold, driving wind and icy snow? Below are tips to help you and your horse not only survive but thrive during yet another frosty season.
Your number one responsibility to your horse during winter is to make sure he receives enough quality feedstuffs to maintain his weight and enough drinkable water to maintain his hydration. Forage, or hay, should make up the largest portion of his diet, 1 – 2 % of his body weight per day. Because horses burn calories to stay warm, fortified grain can be added to the diet to keep him at a body condition score of 5 on a scale of 1 (emaciated) to 9 (obese). If your horse is an easy keeper, will not be worked hard, or should not have grain for medical reasons, then a ration balancer or complete multi-vitamin/mineral supplement is a better choice than grain. Increasing the amount of hay fed is the best way to keep weight on horses during the winter, as the fermentation process generates internal heat.
Research performed at the University of Pennsylvania School of Veterinary Medicine showed that if during cold weather horses have only warm water available, they will drink a greater volume per day than if they have only icy cold water available. But if they have a choice between warm and icy water simultaneously, they drink almost exclusively from the icy and drink less volume than if they have only warm water available. The take home message is this: you can increase your horse’s water consumption by only providing warm water. This can be accomplished either by using any number of bucket or tank heaters or by adding hot water twice daily with feeding. Another method to encourage your horse to drink more in winter (or any time of the year) is to topdress his feed with electrolytes.
It may be tempting to give your horse some “down-time” during winter, but studies have found that muscular strength, cardiovascular fitness and overall flexibility significantly decrease even if daily turnout is provided. And as horses grow older, it takes longer and becomes more difficult each spring to return them to their previous level of work. Unfortunately, exercising your horse when it’s cold and slippery or frozen can be challenging.
First, work with your farrier to determine if your horse has the best traction with no shoes, regular shoes, shoes with borium added, shoes with “snowball” pads, or some other arrangement. Do your best to lunge, ride or drive in outside areas that are not slippery. Indoor arenas can become quite dusty in winter so ask if a binding agent can be added to hold water and try to water (and drag) as frequently as the temperature will permit. Warm up and cool down with care. A good rule of thumb is to spend twice as much time at these aspects of the workout than you do when the weather is warm. And make sure your horse is cool and dry before turning him back outside or blanketing.
A frequently asked question is: does my horse need a blanket? In general, horses with an adequate hair coat, in good flesh and with access to shelter probably do not need blanketed. However, horses that have been clipped, recently transported to a cold climate, or are thin or sick may need the additional warmth and protection of outerwear.
Horses begin to grow their longer, thicker winter coats in July, shedding the shorter, thinner summer coats in October. The summer coat begins growing in January with March being prime shedding season. This cycle is based on day length—the winter coat is stimulated by decreasing daylight, the summer coat is stimulated by increasing daylight. Owners can inhibit a horse’s coat primarily through providing artificial daylight in the fall but also by clothing their horse as the temperature begins to fall. If the horse’s exercise routine in the winter causes him to sweat and the long hair hampers the drying and cooling down process, body clipping may be necessary. Blanketing is then a must.
There are a number of health conditions that seem to be made worse by the winter environment. The risk of impaction colic may be decreased by stimulating your horse to drink more water either by providing warm water as the only source or feeding electrolytes. More time spent inside barns and stalls can exacerbate respiratory conditions like “heaves” (now called recurrent airway obstruction), GI conditions like ulcers, and musculoskeletal conditions like degenerative joint disease. Control these problems with appropriate management—such as increasing ventilation in the barn and increasing turnout time—and veterinary intervention in the form of medications and supplements.
Freeze/thaw cycles and muddy or wet conditions can lead to thrush in the hooves and “scratches,” or, pastern dermatitis, on the legs. Your best protection against these diseases is keeping the horse in as clean and dry surroundings as possible, picking his feet frequently, and keeping the lower limbs trimmed of hair. Another common winter skin condition is “rain rot,” caused by the organism Dermatophilus congolensis. Regular grooming and daily observation can usually prevent this problem, but consult your veterinarian if your horse’s back and rump develop painful, crusty lumps that turn into scabs.
