Cold weather water issues

With the cold weather now upon us, be sure your horse is drinking plenty of water.  They don't move much in this weather, but they still need to hydrate the food that they consume.  Expect a 1000 lb. horse to consume at least 5 gallons a day.  Adding plain table salt to the hay &/or grain is helpful in many cases.  If the water buckets are connected to electrical outlets to keep the water warm, but sure they are working and not shorting out!
