We are in the midst of training our newest cow, Mary to be a milker. Mary was the only springing Jersey heifer that I could find within a few hours drive. Mary originated from a small dairy but had been bought with a group of other heifers and raised on a beef cattle ranch. No time had been put into training and so she had no idea what was in store for her. Training a 2 year old to milk is not impossible, it’s just even more trying and difficult than working with a heifer from birth. If you are wanting to have a milk cow for yourself, the first one should be already trained. You’ll pay a great deal more for her, but it’ll be worth it.
This following link is a pretty good article on the subject.
