gendronf,
I am new to bailing hay. Last summer was my first time to ever do it. So i am not sure what you mean when you are referring to haylage ?
And are you saying that to get the best quality of hay it needs to be bailed about 6 hours after it has been cut ?
To get the best quality you bale at 50-60% humidity. In my area, if I cut the hay today, I bale it tomorrow.
And if i understand you right. Even though the hay that you bailed had gotten rained on it was still of good quality if it was feed out in early winter ?
If the job is done right, moisture 50-60%, enough plastic, wrap in the next hours maximum 4-6 hours, and a bale of good density, 12 month later, the bale will be of top quality. If the bale was made with wet hay, give it to the cows as soon as possible. It's won't last as long as the perfect ones. If you wait to the winter time, the bale will frosen and become hard like rock.
You know there was a old man cutting and bailing hay close to where i was. And he cut his hay and was bailing it the next day. He said pretty much what you are saying. He said if you wait to long the hay has absolutley no nutritional value.
When the hay need to be cut,you should cut it because the nutritional value is optimum. if you wait there is a lost in
nutritional value. If you cut it at his optional value and let it dry more than 50-60% moisture, and wrap it, the cows will prefer the more humid stuff. If you bale it at 30% insteas of 15% you will pick up the leaf not only the sterm.
But wont bailing hay that green mildew ? I ask the old man the same thing and he said it was not no big deal if it did ? Now on horse hay mildew will kill a horse so it has to be dryed out enough that it will not mildew.
