  8. %Diet forage to meet minimum NDF from forage

  9. Silage Replacement

  10. By-Product Break-Evens

  11. How much to feed? Feeding limits i.e. DDG at 10 to 20% of diet DM a reasonable target depending upon diet formulation constraints i.e. High Fat & P and Low Lysine impediments to higher inclusion rates Least cost ration formulation for specified nutrients i.e. CP, RUP, NDF, Starch, Fat, NEL, etc., etc.
