Just how much your horse will need will depend on its weight.
According to the Ontario Ministry of Agriculture, a full-grown horse should eat about 15 to 20 pounds (6.8 kg to 9.1 kg) of hay a day.
That is 1.5 percent to 3 percent of its body weight if it weighs about 1,000 pounds (450 kg).
How much food should a horse eat a day?
Measure feed accurately and feed consistently
The average thousand-pound horse who relies on hay for all their forage typically eats fifteen to twenty pounds of hay per day. Most hay is dispensed in flakes; however, the amount of hay in a flake can vary greatly, depending on the size of the flake and the kind of hay.
How much grain should a horse eat daily?
It is recommended that the diet contain no less than 1 percent of body weight of roughage such as hay, pasture, etc. For example, a 1,100 pound horse requires at least 11 pounds of roughage. It also is important not to over feed grain to horses because this can cause digestive upset such as colic.
How do I know how much to feed my horse?
By calculating the total amount of feed per day we know he needs a total of 12.5kg of forage and concentrate a day. And to work out the total amount of forage a day: 2.5 x 80% = 10kg of forage per day. So, a diet of 2.5kg of concentrates and 10kg of forage equals a total amount of 12.5kg of feed per day.
What feed should I feed my horse?
Feeding rates recommended for concentrate feeds are based on feeding with good quality grass hay. If using good quality alfalfa hay, reduce the amount of Purina feed recommended by 1/2 to 1 lb/day. Make feed changes gradually over 7-10 days. Clean, fresh water and salt should be available at all times.
