Why are they going to walk forwards on a treadmill? Do you propose dangling something in front of them that they can't get? That sounds like the plot of a cartoon, not anything that actually works. What happens if a cow slips on a treadmill and breaks her leg? The medical costs may outweigh the energy profit.
Horses have been put on long levers and made to walk in a circle, to mill corn and so forth. But I think those horses are supervised and directed by a human, same as for plowing. You have to pay a human to get that energy from the horse, they don't just do it naturally.
