DM
. The ration must include corn (9% CP
DM
), cottonseed meal (42% CP
DM
), wheat silage (10% CP
DM
) and tallow (0.0% CP
DM
). Wheat silage and tallow fixed at 30% and 2%, respectively. Use the modified algebraic method to formulate this ration.

2.5 Points:
One of your clients asks your help to formulate a diet that meets his growing steers' requirements. He has enough Barley grain, Bermudagrass hay, and Cottonseed meal to feed all his animals for the period that he needs. The diet that he is currently feeding
is shown in the table below; however, as a good nutritionist, you realize that the CP
DM
% is not meeting the animal's requirement based on how much they are eating. You decided to increase the CP%
DM
of the diet to 15%. To do that, you decide to replace some of the Barley
grain with Cottonseed Meal and keep the same % of bermudagrass in the diet. Calculate what is the % of each ingredient in the new diet and provide to your client the amount of each ingredient that he must mix into a 250 lb batch (
DM
). Use the substitution method to formulate this ration.
