In the winter, almost more important than the temperature is whether your horse gets wet (and cold). Being cold and wet is very chilling and a horse will eat a lot more to keep warm. Our mares have free choice hay all year. In the dead of winter when it's cold and wet, they'll go through a round bale in 7 days which comes out to about 35 lbs/horse/day (about 3.5% of their weight). The drier you keep them (e.g. using a rain sheet or blanket), the less hay you'll need.
On the sixth day, God created the Quarter Horse.
On the seventh day, he Painted the good ones.
