I live in dairy country, where the primary hay available is alfalfa. The dairy people like it very rich–high protein is evidently good for lactating cows.
I don’t know of any method of lowering the protein after it’s baled. I can soak much of the sugar out of it, but I don’t know if soaking will lower the protein content as well. I don’t want to feed my horses a hay that has a 26% protein reading. Might not hurt, but otoh, who knows?
Right now, I’m combining the high test alfalfa with Bermuda hay. Guess what they eat first! :eek::eek: And guess what they throw out of their feeders and walk on!
