I still can't decide!!! We are moving onto the land next month (it's actually 3 acres, not 5. My mistake.) and we already have permission to have a cow, although I'm sure that would extend to goats, too. I can just see the pros and cons with both!
On cows, I think they are prettier. I want a Dexter, and I just think they look so sweet. I also like that breed because they are smaller, their milk makes a lot of cream, and they don't give AS much milk as a bigger dairy animal. But they are so expensive!!!
Goats: I like that they are cheaper, but I have never had goats milk and it eeks me out, for whatever reason. I don't like that I won't be able to get as much cream, because I really like making butter, and I want to try making cheese, and have cream for all the other things I want to do. I like that they are smaller and will be cheaper to feed overwinter. I like that they'll help clear some of the overgrown pasture.
So basically, I want a cow that costs as much as a goat.

Where is a good resource for finding a pregnant cow, particularly when I want a specific breed? (I'd be happy with a Jersey, too, but I really don't want a bigger cow than that.) I've looked on the Dexter website (
http://www.dextercattle.org/ ) and found links to farms relatively near mine, but even the heifer calves are around $800, and then we'd still have to breed her later. These farms all seem to be practically show-quality animals, which I don't care about so much, I just want a good milker!
