Mix-30; It contains no NPN. I haul and feed it myself, cost is up to $150.00 per ton @ the feed store. It is a tremendous feed for developing hfr. calves. My breed up has been quite good since I started feeding it. Fed it now for 4-5 years. Consumption control is the key. There is nothing to add to control consumption. The lick wheels might work. The thing one has to remember while feeding it, like any liquid feed there are highs and lows in the overall average.
I do agree Faster Horses alfalfa is probably a better feed overall.
