Starch digestibility was greater with the high moisture and with the finely ground corn treatments.
In addition, the high moisture ensiled corn treatments had reduced ruminal ammonia concentrations.
Lower ruminal ammonia concentrations were obtained with the high moisture ensiled corn treatments, and there was a tendency for reduced ammonia concentration with fine grinding.
The CrPr and corn treatments interacted over time to affect yield of 3.5% fat-corrected milk (FCM) during both the treatment and carryover periods.
In decaying roots of corn treatments, maturity index values and the relative abundance of nematode predators was greater in the Bt hybrid than non-Bt isoline with insecticide.
Corn treatments were dry shelled corn, high moisture ensiled ear corn, and high moisture ensiled shelled corn, either coarsely or finely ground.
Daily and cumulative DMI were not affected by treatment during the PP period, but CrPr and corn treatments interacted over time to affect daily DMI during the carryover period; DMI was generally higher for CrPr/HMC, lower for Con/DC, and intermediate for CrPr/DC and Con/HMC from 29 to 84 d PP.
