I am interested in planting a winter pasture. Not for the only feed source, but to suppliment and decrease the amount of hay needed. I am raising goats and calves, but may have sheep and pigs by next winter. Any ideas? I will be using about 5-10 acres. I know some people use corn, but I am hoping to find a grass/legume combo. I am sure the deer and moose would eat all of the corn. I am in central Ontario, zone 3.
