Thanks for all the advice guys. I guess I should say a little more about the land, since I am absolutely interested in happy animals!
It's not irrigated, but has a seasonal creek that stays green with herbs like mugwort, himalayan blackberries and yarrow. It is also heavily shaded by a green canopy. There is also a black walnut orchard on the far side of the house, and a wide-open five acre pasture that I'll probably work with them to get dry-farmed with wine grapes, something I've become good at. Obviously they can't coexist, but hopefully a smaller breed of cow, like a Dexter, on that ten acres wouldn't be too much. The property is about 2200 feet up into the Sierra Nevada foothills, in a cooler, wetter area. If it rains anywhere this low, we get some. Supplementing with alfalfa would be okay, but I am interested in setting some pigeon pea and cowpea in a sequestered area for later grazing, and possibly haying half the property for the leaner summer months. Is that robbing peter to pay paul or would it work?
I am committed to sustainable farming and happy animals. It would be cool to have a dairy, but the Dexter is a dual-purpose breed, and can be slaughtered if the game doesn't play out. It would also be possible to move the cow to another pasture, though I would need to fence it. Anyone have any experience with cattle and electric fencing?
Thank you all for your insights and advice. This is proving to be a most useful community!
