Often one has to translate things into understanding by the animal at hand.

Monkeys learn quickly. Cows oddly enough can also learn quickly in social cohesion. So one cow figures something out; the others often quickly adapt and learn too. So the main step is the initial hurdle to overcome. There are lots of videos about this on youtube, starting with simple ones such as scratch-objects where cows rub against and it helps them scratch areas they can not easily reach on their own.
