Usually the apatite of your horse can answer that for you. But it depends on the weight of the horse and what type of work the horse does. Also on what type of feed you give your horse. If there is a lot of food left after your horse walks away from it, and you notice your horse getting fatter,you need to cut back a little. If your horse tries to eat everything in sight that is eatable and you can see the outlines of its ribs and hip bones, you need to feed more.
There are six boxes on your left set out like this: 1 2 3 4 5 6 Click on Number 1. Then choose how much food you need to give them. To know how much food u need to give your horse you need to look next to the place where you choose how much food you give your horse, there should be something like this: 0/13.2 On the left it shows how much food you've given your horse. On the right shows how much food you need to give your horse. Ihope this answers your Question.
