I believe the answer is... Feeding a horse.
you should probably be feeding your horse grain instead of liquids
This can depend on the surgery the horse is going to have, you should always ask your equine vet about feeding prior to surgery just to be sure.
Feeding horses is a tricky subject and is something that you should usually consult somebody on if you are not sure. Not only should your horse be given hay during the day (at most places 2 flakes AM, 2 flakes PM -- plus turnout), but any active horse should also have grain included in its feeding regimen. Grain feeding also varies by horse depending on how much the horse is being worked and big your horse is. Usually, if you don't want to consult with someone, you can go off the feeding instructions on the grain that you are feeding. Just make sure that you are feeding enough (but not too much). Feedings should be split into at least two sessions because horses were not meant to take in large amounts of food at once and over-eating can cause colic. If you see that your horse is getting a little fat you can either decrease the amount of food, or up it's exercise to match the food that you are feeding. If your horse is losing weight (or not gaining enough) than try adding more feed to its feedings. As for a go off of though, one of the smaller Arabians at the barn got 2lbs in the morning and 2lbs at night, plus its hay and turn-out, but he was a show horse and was on a tight training schedule, so your horse may require less.
still at least once a day
Yes and no. A horse should have a routine, but it can actually be detrimental to the horse to be fed at the exact same time every day. You can safely vary the feeding time by one hour early or late with no ill effects.
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.
Anything to do with the care of the horse is known as stable management.
That all depends on what you're feeding it!
Trickle feeding
