Intake and digestibilities or corn silages of early and late maturing varieties which were grown in low and high plant populations and ensiled at low and high dry matter contents were studied with Holstein steers. The silage dry matter ranged from 23.0% to 47.8%. No consistent difference occurred in intakes due to treatment. Dry matter and energy digestibilities were greater (P<.05) for the low dry matter silages. Low population corn silages had greater (P<.05) energy digestion coefficients. Protein digestion was consistently less for the high dry matter silages. None of the interactions studied were statistically different.
