Within a row, values lacking common superscripts differ when F-test was significant (P < 0.10).

95:0 = 95% corn silage, 0% MDGS; 15:20 = 15% Corn Silage, 20% MDGS; 15:40 = 15% Corn Silage, 40% MDGS; 45:20 = 45% Corn Silage, 20% MDGS; 45:40 = 45% Corn Silage, 40% MDGS.

F-test = P-value for the overall F-test of all diets. Int. = P-value for the interaction of corn silage × MDGS. Silage = P-value for the main effect of corn silage inclusion. MDGS = P-value for the main effect of MDGS inclusion.
