It's done by selectively handbreeding and choosing the best livestock to mate each generation. Cull the weak and low quality. Cattle can only be at the same quality as the fodder that you're giving them or eventually their quality will drop to the quality of the food. This quality drop won't display but it will effect products produced by these animals. So there's no reason to feed them higher quality fodder than they are, but a huge incentive to not feed them food lower quality than they are.
