What to do with very mature alfalfa

I have a alfalfa field that has now been 45 days since 1st cut and it is beyond full bloom with a few blooms left but mostly seed pods. Never had a field get this mature and I don't think it's going to make that good of hay because almost half of the length of the stems the leaves have fallen off and it's going to be very stemmy. I don't have a market for cow hay or the option to round bale it.

I thought about maybe I could let it mature out and combine the seed to plant next year but it doesn't appear that the pods are filling out very well so I'm guessing the seed yield would be pretty low? Don't really know much about alfalfa seed production or if it would be worth trying to do.

What does everyone else do if there alfalfa gets this mature and what would the feed value be if I would bale it at this stage?
