We have been feeding baleage for over 10 years. It's the only way we can put up our first cutting hay in decent condition. We try to put our 2nd cutting up dry bales.
We hire it done. It is put up in IN-LINE wrap. Meaning they are wrapped continuously in a line. Not "marshmellows" or "tubed".
Yes, it smells great. It is the best way to put up high quality hay. Whatever the feed value is when it is cut, that's about the same as when it gets fed. Baleage has a "cool" cure, unlike silage that heats during curing and destroys some of it's protein.
Even most of the dairymen around here have figured out a way to feed baleage. Cows milk great on baleage.
Did you buy yours?
Tom starts mowing in the morning, and about 11am Ron starts baling. We can put up about 100 - 150 - 4' bales/day. They only mow what we can put up that day & early the next. And you NEVER bale it unless you can wrap it - usually within an hour of baling. If they don't get wrapped - they will start to HEAT and that spoils the bale.
Our 4' bales weight about 1300# and usually about a 50-75% moisture. They say you don't want to bale less than a 50% moisture.
Cattle LOVE it!!
They are better quality hay than my dry cows need, so I try to make sure they clean up everything before I feed them again. But once they calve, they get all they want.
