Yes I can see you know nothing about horses.
Working horses need high energy food additionally to grass, ie grain or
these days "concentrates".
In days of yore,large areas of land were set aside for growing oats just to
feed horses and oxen.
You don't get energy from nowhere.

Grass Harry. All grains (wheat, barley, oats etc), they're all
grasses, or didn't you know that? Concentrates are made from them. So
why have all these green machines, the horses, disappeared, Harry?
It's because they've been replaced by infinitely more efficient
machines that burn fuels such as coal or oil.
