For years, I have been wanting a cow just for milk, and there is a possibility that in the spring that we can have a cow when my dad gives an ok. We just got 2 bull calves to raise as a steer, we will have one to be butchered, and sell the other one to pay for the cost of raising them, and feed. Right now the calves are in my coop, and we will build them a 12x12 shed with at least 3 to 5 acre pasture in the spring. My goal to have the cattle grass-fed as much as possible, and am wondering is it possible to have a dairy cow fed just grass in the growing season, hay in the winter, and no grain at all? We just want a few gallons of milk a day, and am thinking of finding a jersey cross type. I am still learning, and will appreciate any links and info regarding grass-fed dairy cows. Thanks.
