Thanks for your response.
I honestly don't know the nutritional value of my hay(!). They sell it as #1 or #2 quality horse hay, and I always get #1, because it seems to be the best quality. Sometimes #2 quality is musty or dusty or dirty or full of weeds. I am kind of picky on my alfalfa!
What I am feeding is leafy, green, and fine-stemmed. Probably too rich if anything, but I would rather have super nice alfalfa and dilute it down with bermuda than get hay that is musty and dirty and that I don't feel safe feeding.
So I guess I can't answer to the feed quality of my alfalfa, only that I try to buy the cleanest and best-looking available to me.
