Here on the farm of my relatives, where we were staying in Holland, is seen the procedure for the daily feed. Minerals and "straights" first, then a bite of grass silage, then Maize silage. The feeder weighs out the stuff so you can go back for more if necessary. I was shown the brochure by Triolet who are based in Holland, and the top of the range machine is awesome! And expensive.
