Our experience with it was bad. I planted some for grazing, and a neighbor planted some for haying. Both of us got very nice stands that came up and looked great early on. What we found out was it couldn't take any kind of pressure, not grazing pressure for sure and haying is almost as bad unless you are getting lots of moisture.
Our cows have been on 31 for so long it really doesn't bother them, and that's what we are planting again, the old KY31.
Maxq is good for a ditch bank to control erosion maybe, but thats about it, in my opinion. Here in SC anyway where we get a fair amount of mid 90s plus for a good part of the summer.I dont think we ever will get cold enough to cause a any problems with it, but it that could be a factor too.
