Instead of herding cattle with trucks, humans on foot, or Kawasaki "mules," they're doing it with horses and men — not cowboys, but stockmen. Boatwright, whose official UGA job description is "Farmworker II," and O'Mara, a senior agricultural specialist, ride cow ponies, two American quarter horse mares named Crystal and Sunny. Cattle seem to instinctively see two-legged humans as predators, but they don't have to overcome that fear with horses, Boatwright said. To a cow, a horse is first a fellow four-footed vegetarian, a creature that some level speaks the same language, albeit a different dialect, he maintains. The role of stockman is somewhat new for O'Mara, who grew up in a south Florida city before studying at Abraham Baldwin Agricultural College in Tifton and the University of Georgia. Boatwright hopes UGA's use of horses and stockmen will accomplish another goal besides sustainability and reducing psychological stress on the university's cattle.
