Maximize Value of On-Farm High Moisture Corn Grain Products

High Moisture Corn in Bunker

The types of HMC grain products produced on dairy farms are high-moisture shell corn (HMSC); “earlage,” which is itself a generic term that encompasses high-moisture ear corn (HMEC); snaplage and, more recently, toplage, which is somewhere between high-cut corn silage and snaplage.

The fineness of grind for HMSC will depend on the harvest DM or moisture content: The higher the DM, the finer the grind required. Harvesting these products too dry will present challenges for ensiling, aerobic stability and starch utilization in the ration when fed.

These are high-starch, high-value products need attention to detail at ensiling and feedout to ensure the maximum value in the ration is obtained. Without the use of effective, research-proven inoculants as part of an overall good management program, these high-moisture corn grain products can readily become aerobically unstable during feedout due to an increase of the wild yeast population on the product when the silo is opened and exposed to oxygen. When added to a lactating cow TMR, high levels of wild yeast can reduce DM intake and disrupt rumen function. The likely consequences are lowered rumen fiber digestion, reduced milkfat content and loss in average daily milk yield.
