Andy has been involved in beef cattle research since 1982, which has resulted in over 90 technical and scientific publications, including 49 in refereed journals, and 58 invited presentations at scientific or producer meetings. Research has focused on identifying basic mechanisms regulating reproduction in cattle in order to develop methods and management approaches that improve reproductive efficiency. Goal of basic research at Ft Keogh is to identify genes and physiological traits associated with enhanced production efficiency under sustainable nutritional regimens. Traits of economic importance being evaluated include growth, feed intake, ultrasound carcass characteristics and age of puberty in heifers and bulls; and re-breeding reproductive success, body weight and condition, weight of calf at weaning and longevity of production in cows. Results from research will provide opportunities to improve efficiency of beef cattle production by developing methods that minimize animal input requirements and enhance lifetime production characteristics.
BS - New Mexico State University; major, Animal Science; B.S. 1982

Current Research Projects:
Identify genetic and nutritional processes controlling feed efficiency and the level and duration of production in beef cattle.
Developing management strategies that minimize harvested feed inputs during development of replacement heifers and winter feeding of cows which ultimately improve lifetime production efficiency under range conditions.
