Deepsouth, I didn't plant winter grazing for the cows last year. Thought I had enough hay and corn, but I mismanaged my resources. I put the cows in the woods and let them scrounge for about a month. I try and put hay out also when I have it. The more the cows are in the woods, the better the woods get for the cows. Jogeephus, told me it takes 20 acres of woods per cow per year to get by. So I just figured 2 acres per day per cow and let them have at it. The cows did a better job eating the woods this year than last year.The first couple of days the cows make a big fuss, after that they shut up and start scrounging. I'm reluctant to push them really hard, because I have ferns, black cherry and some other toxic weeds.
