Whenever possible, Kershaw would use an International grand champion bull or a son of one in his breeding program. One such bull was Plowman (son of the 1911 International grand champion, Kloman). Kershaw purchased Plowman for $3,050 after he won his class at the 1917 International Livestock Exposition in Chicago, IL. In 1919, Kershaw won the Grand Champion Steer (over All Breeds) trophy, with Muskogee Boy II, the brother to Muskogee Boy at the Texas State Fair in Dallas. That same year, his prize bull, Plowman, won the Grand Champion Bull trophy at five of the nation's most prestigious livestock shows, including the American Royal Livestock Show in Kansas City, MO; the Southwest American Livestock Show in Oklahoma City, OK; the National Western Stock Show in Denver, CO; the Southwestern Exposition and Fat Stock Show, which was later named the Southwestern Exposition and Livestock Show in Fort Worth, TX and also at the Kansas National Live Stock Show in Wichita, KS.
