To be fair you can keep a cow milking for LONG after it gave birth, but yields are a bit lower and baby cows are very valuable in themselves, which is generally the same kind of problem that keeps most bad farming practices going. Dairy farming is already a bottom of the barrel low margin business. And running a dairy farm while not maximizing calf output is like running a low-yield gold mine while dumping gem quality emeralds out with the tailings. Yeah it can be done, but you would be foolish not to do both, especially if it means your competitors across the road are able to squash your business with far higher capital returns after a few years.
