Most every fall I no-till wheat and a little fescue in my pastures. The wheat will come up and give some fall grazing, plus also some early spring grazing as well, and the fescue of course just adds to what's already there. I have used rye, and it works about like wheat. I've never planted oats for grazing, but can't see why they wouldn't work, although oats planted in the fall do not usually come through the winter good.
The best thing to do is to contact your local extension office and county agent for their advice. Also, most of the larger farm supply stores will have people who work there who can help.
