This will depend on the individual horse. Some horses for one reason or another will need more or less food than others of his size. The type and quality of his feed is just as important as how much. As long as your horse is healthy and worm free and his teeth are in good condition I would try 1 to 1 1/2 flakes of a good oat or oat mix hay twice a day. If he is out in pasture and has plenty of grass there you may want to cut it down a little. Be careful about how much green grass he is getting from his pasture. It is very easy for horses of his size to over indulge on rich green grass and end up with laminitis (founder). Sometimes finding the right feed program for a horse is a trial and error operation. Watch him closely if he has dropped weight or has gained weight. Adjust the amount depending on how he is looking. Horses his size are usually easy keepers.
Feeding a horse beet pulp can vary from horse to horse. Depending on if you have others in with them or how much you horse takes in daily. For me its usually 1 and a half scoops but again it varies. That is a question for your local feed store or your local vet.
The height of the horse isn't so much a factor as the weight and age of the horse is. A horse should get between 1.5 and 3% of it's bodyweight in feed daily and no less than 50% of the total daily diet should be forage (hay and/ or grass.) Horses in moderate work typically get about 2-2.5% of their bodyweight in feed daily and of that total no more than 25-30% is concentrated feeds such as grains or bagged feed, the remaining 70-75% should be some kind of forage.
An adult horse should eat between 1% and 3% of it's own body weight in feed daily/ As an example, a 1,000 pound horse would require 10 to 30 pounds of food a day.
You should feed your horse 12 to 15 pounds.
You optionally feed your dog at 7AM in the morning, and feed them at 11Am and at 3PM
Correct! A horses diet is rationed on the weight and size of the horse and how much daily exercise it does. Correct! A horses diet is rationed on the weight and size of the horse and how much daily exercise it does.
Sweet feed, sweet feed, sweet feed
It depends on the horse. If your horse is fat then you need to cut down on the horse feed, but if your horse is too skinny then you need to increase their feed until the horse gets back up to his/her weight.
Alfalfa is highly nutritious and rich in Calcium. But it can cause Entroliths (Stones) in he intestines/stomach. It's recommended that alfalfa not make up a large portion of a horses diet. 5 -10 pounds is about as much as you should feed daily.
how big is the animal??
It depends on how much the horse is ridden, and whether or not the horse lives in a pasture, stall, or has limited turn-out.
