Hutjens (1999) reported that milk performance was significantly better when the cattle were fed with ground corn. Aldrich (Akey Inc.) compared digestibility of various corn particle size and distribution and conclude that to have 80% digestibility, particle size of 0.5 mm should be used (for 16 hr incubation).[22] A research team from the University of Maryland and USDA studied the development, fermentation in rumen and starch digestion sites in lactation cow feeding on corn grain from different harvests and differently processed, and concluded that digestible, metabolizable, and heat energy were higher for high moisture corn compared to dry corn. Grinding increased DMI and resulted in increased yields of milk, protein, lactose, and solids non-fat.
