Yeah, what Dun said.
Another option that we're doing is to make hay off some of our paddocks. We have paddocks we rotate our cows through. Some can be hayed, some can't. We've got a couple paddocks we had grazed twice, came back through 4 weeks after that last grazing and made 3,000 - 4,000 lbs of hay/acre. Those acres will go back into grazing rotation in 4 weeks if the rains continue. If the rains stop, we'll put the cows on a sacrifice lot and feed them that high quality hay harvested weeks ago. And those paddocks that had hay taken off will grow like crazy after being rested, a whole lot better than grazing overgrowth during a drought.
