Jul 06, 2009 The limestone I mentioned is called Free Flo Limestone on the feed mills sheet. In a 1,000lb batch there is 4 lbs. My understanding is that it is a cheap form of calcium to go along with the 1 to 1 mineral. Apparently many of the diary feeds use it as a cheap form of calcium also. I dont think in that form it is as easily absorbed.
