Have about 10 acres with heavy ripe fescue and summer grasses growing as well no weeds as grazon was applied back in early spring . I have enough hay, would turn cows in to clean up then clip the stems later or go ahead and take the grass off. The cows I'm sure will make a mess out of it but with time and water being in pasture 27 cows with calves should work on it pretty good as i can shut the gates and let other grass rest . Will the ripe over grown fescue provide descent gain ?
