1. The ration printed out by the computer is the “Holy Grail” of many nutritionists and is considered to contain the final output of our accumulated nutritional knowledge coupled with the latest chemical analysis of the feedstuffs involved.
2. This second ration is what actually goes into the mixer. It rarely matches the print-out as accurate measurement of ingredients amounts becomes more difficult as the size of the mix increases.
3. This is is what is actually delivered to the feed bunk. If the ingredients are not properly mixed there will be different feeds delivered to different parts of the feed bunk.
