Notes: MC, moldy corn; MW, moldy wheat bran; control, 0% moldy corn; 25% MC, 25% moldy corn; 50% MC, 50% moldy corn; 75% MC, 75% moldy corn; 100% MC, 100% moldy corn; 100% MW, 100 moldy wheat bran; 100% MW + MC, 100% MW and 100% MC. Values are presented as the mean ± SEM. Within a row, values without the same lowercase superscript letters differ significantly (p < 0.05); p1, significance of linear and quadratic effects; p2, significance of effects of 100% MC, 100% MW, and their interaction. **, p < 0.01; n = 6–7 per group.
