andrewNZ: I'm sorry, but the idea that cows are supposed to eat only grass is just wrong!
Cows are herbivores, and by definition are supposed to eat plants, any plant material is fine if they like it.
Cows will eat just about anything plant based, and will actively seek out things they like. They also like variety just like we do.
