i always thought domesticated cows were bred to produce milk all the time. i will search a little to know more about that

edit: i have searched and dairy farming indeed works the way the person i replied to said it worked. to add, that can be done so much to a single cow it can cause diseases and infections on the cow

edit2: i forgot to say that those things dont count as rape, since rape means forcing a person to do sexual things without their consent, so by letting a bull do the work i feel its completely fine. artificial insemination is a different story, and i just seriously dont want to think about it
