For lactating dairy cow, the allocation of ingredient was based on first using the ingredient with the higher protein expression until 100% of daily intake is achieved. Thus, in this scenario, 100% of the dairy cow diet was achieved without maize grain, and using gluten feed at 20% of inclusion rate, although OECD, 2009 indicate 30%, which would exceed the 100% of the total diet.
