Although grain does not provide as much of an internal warming effect as hay, it is often necessary to supplement a horse's winter ration with additional grain to boost calorie supplies. Cold temperatures increase the number of calories a horse needs to maintain body weight, as well as support activity or production. Because a horse may digest feed less efficiently as the temperature drops below the horse's comfort zone, additional feed may be required to maintain body weight and condition. In general, feeding an additional 1/4 lb. of grain per 100 lb. body weight to nonworking horses will provide adequate calories during cold, windy and wet weather. Working horses may require up to an additional 1/2 lb. per 100 lb. body weight, depending on workload, to maintain body weight during cold weather.
