Interpretive Summary:

Technical Abstract: Two Mycogen corn hybrids (TMF2662 and TMF108) were chopped at 37-40 percent DM and a theoretical cut length of 9 to 19 mm. The longer cut silage was rolled through a processor mounted on the forage harvester with roller spacing of about 1 mm. Control and processed silages had similar particle size distribution. Sixty-four early-lactation Holsteins were fed once daily with a TMR containing one of the four treatment corn silages. This completely randomized 2 x 2 factorial design was conducted for 124 d. Diets contained 37.5 percent corn silage, 12.5 percent alfalfa silage, 26.0 percent high-moisture shelled corn, 11.6 percent roasted soybeans, 5.8 percent soybean meal, and other minor ingredients. Dietary NDF and CP averaged 27.1 and 18.0 percent, respectively. Grain contents (percent DM) for TMF2662 and TMF108 silages were 43 and 48 percent. The TMF108 treatment resulted in a lower milkfat test. Processed TMF108 had the highest milk production. Processing tended to increase milk production and decrease grain in the feces.
