I bought a Jersey cow that was in the process of being dried up. she is open and was giving about a gallon of milk when we got her although the folks had not built her for about 6 weeks. we milk her once a day every now and then and get about a half gallon to a gallon of milk. I'm under the impression that keeping an open cow in milk makes them easier to breed back. We have been offered a bottle beef I'm wondering if she will just build up her supply again to put a calf on her or would we also have to bottle feed it? I was planning on continuing to milk her a little bit until we get the opportunity to breed her back. we will be putting the calf in with her either way but I would like to make sure I have any supplies that are needed without having to spend more than necessary we will probably get a small bag of artificial calf starter and a bottle just in case we need it on hand.
