Question for grass and other cow people

[Guest]

I assume he was talking about bloat risk not nitrate? never much nitrate risk with alfalfa anyway it's more a problem of annuals. Bloat can be managed, Alfasure in the water for one. We graze alfalfa in the fall and don't worry too much about bloat - less risk than in June. Grazing doesn't seem to cause winterkill as bad as haying either in my experience.
For haying I'd be waiting until it does frost kill then get in the next day and cut it to reduce winterkill potential.

that's what I was thinking . beings there seems to be a shortage of feed .it still makes ok feed that way ? I don't know anything about cattle , but had heard something once that it was no good for feed after even a light frost? grazing isn't an option . just want to clean it up for seed production next year . it was cut for dehy but not until about August. 10 for first cut , so was just thinking of this for an option if they don't cut it again .
thanks everyone for the replies
