Once.
Winter wheat and winter rye cross I believe.
It has very good food value which explains the dairy application.
I think winter rye is a better fit for the raising beef in the Polar Vortex.
I used some last year. I think its a great forage however I think Rye give you more total forage however Rye is very hard to come by so I would plant it again if I couldn't get Rye. I would mix it with another small grain like oats and not plant it by its self.
