Don't get in too much of a hurry. As mentioned it doesn't really like this cool wet weather. We used to raise some 30 years ago when we had cattle and were short on hay. It would produce in near drought weather when nothing else would. You can make baleage, or dry it down and make hay. It can be tough to get dry enough, not a problem in a drought. Ha Ha. You need to be cautious about the toxic issues, but as I recall you can bale or pasture after a killing frost. Something else to be careful about is feeding. We usually tried to square bale it so we could mix it with other, poor quality hay. The cows would fight for it so we would spread it out so they all could get access to it.
