This time of year brings not only chilly temperatures and frosty mornings, but also a decline in forage growth due to the shorter days and colder temperatures. It’s tougher to match the increase in calories needed to maintain weight, stay warm, and certainly for a youngster to grow or a mare to nurse a foal. Minimum essentials for horses and other animals living outdoors are adequate nutrition, whether forage, concentrated feed, or both, along with clean water and some type of shelter. Being able to provide water instead of a block of ice is also critical. Feed and farm supply stores sell tank de-icers and heated buckets or tubs that come in handy. Making an investment might save you the cost of a vet bill later, or even worse, the loss of an animal as a result of cold weather dehydration.
Providing good quality, nutritious hay is another critical aspect to winter management of horses. This is the time of year where hay supplies can get thin, so planning ahead and purchasing enough hay to get through the winter is critical. When temperatures get below freezing, winter pasture growth reduces tremendously, and hay is our only forage option. Horses, along with all livestock, need hay to stay warm. Hay and other forages are digested in the cecum and large intestine of the horse, and this digestion process is the primary source of regulating body temperature. Many horses can maintain their weight through the winter with just an increase in hay consumption. Those that are harder to keep weight on or older will often need a gradual increase of grain as well. Horses should consume at least 1.5% of their body weight in hay during cold periods. For example, a mature 1000 pound horse should consume 15-18 pounds per day of hay to meet these temperature needs in cold weather. It’s also important to pay close attention to body condition during these periods, and actually “feel” your horse. A long hair coat or winter blanket can often cover up thin spots on a horse, so be sure to examine your horse closely and get a feel for where your horse’s ribs, backbone, etc. are and how much fat or “cover” there is over and around them. If a horse given plenty of hay is having trouble maintaining weight, increasing fat to the concentrate diet may also be helpful. Many “high fat” feeds are on the market just for this purpose.
These are just a few tips to help you and your horses get through the brisk winter days that are starting and will be here for a while. For more information or advice, don’t hesitate to contact your local county extension agent or your veterinarian.
