A free automated tool to help with winter horse care and management.
Feeding a proper amount of quality hay during the cold winter months is one of the best ways to help your horses keep warm. With a proper winter coat, sufficient water, shelter, and an increased amount of hay based on body weight, a horse can stay healthy in temperatures as low as -40° F.
Sweet Equine provides a feed table based on geographical weather data and horse weight that calculates the amount of hay your animal requires based on current weather conditions.
DailyFeed(1 + .01 * (18-MinTemp))
For every degree below 18° F, a horse needs 1% more calories/energy to stay warm. Our math assumes access to shelter, water, and 2% of body mass intake a day. For example, a 1000lb horse would take in 20lbs of hay a day and would need an approximate .2 lbs of feed per degree below 18° F.
If a horse is wet, then their intake requirements increase even further. Simply click on the raindrop symbol by the weight on the day in the table to see the increased requirements.
