A 134- day finishing trial was conducted to evaluate the effect of milling method and corn type on finishing cattle performance and carcass characteristics. Treatments were applied in a 2 × 3 factorial arrangement, with the first factor as milling method (Automatic Ag roller mill or hammer mill) and the second factor as corn type, either 100% dry corn, 50:50 blend of dry and high moisture corn, or 100% high moisture corn. $ ere was no interaction between milling method and corn type for carcass- adjusted final body weight, average daily gain, or dry matter intake but there was an interaction between milling method and corn type for feed conversion. Cattle fed the diet containing 100% high moisture corn processed with the Automatic Ag roller mill were 4.7% more efficient than cattle fed a 100% high moisture corn- based diet processed with a hammer mill. $ ere was no effect on carcass characteristics based on milling method or corn type. Processing high- moisture corn using Automatic Ag’s roller mill improved feed conversion compared to processing with a hammer mill, but processing method had little effect on dry corn or blended diets.
