Milking a cow requires that you keep the animal producing milk which means numerous pregnancies that produce either another dairy cow that has been born into milk slavery or a meat cow destined for the slaughter house after fattening. I'm not sure where people get the idea that milking hurts the cow as it doesn't. The machines are automated and some are ones the cows voluntarily enter for milking. If the cows don't milk regularly it can be painful for them.
