We switched over to the Purina feeds a handful of years ago because our local feed store doesn't have the custom mix business to keep the mill up and running well. Our custom mixes tended to be extremely variable within each batch, molasses distribution mostly. We've had good luck with it, however we've sometimes run into issues with freshness, especially on the Finishing Touch, and therefore sometimes throwing heifers off feed. We use it the same as rjb for the most part. We will switch back and forth between it and Fitter's Edge when more condition is needed or we want to hold one/freshen one up.
