I'm really hoping cattle farming is more of an abstract game in itself. You get a cow and bull, you provide resources, wait time, you get new cattle and different resources. It doesn't have to have anything to do with the drop rate in game, how well you tend your herd has the impact on how much and what kind of resources you get. You should be able to be more methodical in your butchering so you got more then you would get with the quick instant butcher in the field. Hopefully the resources will stockpile while you are off line or doing other stuff in game. If I have to summon each cow in turn to milk it, I might go mad.
