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. fyi - while 24%-26% starch diets may be

“ideal”, it appears that 21% starch diets are acceptable
