Historic site focuses on future Fort Keogh Livestock and Range Research Laboratory is home to a legacy of beef cattle genetic research Fort Keogh, a U.S. Department of Agriculture (USDA) Agricultural Research Service (ARS) Livestock and Range Research Laboratory, is rich in history and famous for research on animal genetics and rangeland management. Located just outside of Miles City, Mont., Fort Keogh focuses on beef cattle genetics, reproductive physiology and nutrition. History Before Fort Keogh was turned over to the USDA in 1924, it served as an Army Calvary post following the Battle of the Little Bighorn. General Nelson A. Miles, whom Miles City was named after, was ordered to establish the fort in June of 1876 after the deaths of Colonel George Armstrong Custer and Colonel Myles Keogh during the battle. Infantry troops were removed from the fort in 1907, and two years later it was designated as a Remount Station. During World War I, it is reported more horses were processed at Fort Keogh than any other Remount Station across the U.S. On April 15, 1924, Congress transferred Fort Keogh to the USDA for

agricultural research. The earliest range management research was conducted in the 1930s by the U.S. Forest Service and worked to establish stocking rates for both summer and winter grazing on the Northern Great Plains. Fort Keogh was home to flocks of Rambouillet ewes and Bronze turkeys, herds of Belgian, Morgan and Thoroughbred horses, Milking Shorthorn and Hereford cattle and Wiltshire Side hogs. Eventually, all but cattle research was phased out, and since 1986, Fort Keogh has restricted the research herds to beef cattle. Today, Fort Keogh utilizes 50,000 acres of native rangeland, 2,500 acres of dryland planted pasture, 1,000 acres of irrigated pasture and 700 acres of irrigated cropland. The farming operation produces alfalfa hay, corn silage, barley, sorghum sudan hay, barley straw and grass hay – all of which are produced to feed livestock at the fort. Beef cattle research “Our overarching goal is to develop strategies and technologies for reducing costs of beef production, including enhancing effi-

ciency of nutrient utilization and improved reproductive performance,” notes the Fort Keogh Beef Cattle Research web page. “Our approach is of necessity, long-term and multidisciplinary – involving genetics, physiology, nutrition and microbial metagenomics.” Fort Keogh Physiologist Andrew Roberts has been working to identify feed efficiencyrelated genetic and nutritional processes. His work has also focused on developing strategies to minimize harvested feed inputs during heifer development

and winter feeding with the ultimate goal of improving lifetime production efficiency on range conditions. Tom Geary, a reproductive physiologist at Fort Keogh, emphasizes research efforts to identify genes influencing pregnancy success as well as research studying phenotypic traits related to bull and cow fertility to understand and discover fertility markers in cattle. Range Animal Nutritionist Richard Waterman focuses on efficient use of nutrients by beef cattle and how range livestock can retain more of the nutrients they consume. His current work involves enhanced use of dormant winter rangeland forages on animal performance and rangeland response and the influence of nutritional quality when invasive plant

species are disturbed. Rangeland research The range and nutrition research section at Fort Keogh represents a wide range of disciplines, but the collective focus is on improving sustainability of rangeland production. “Objectives are to develop strategies and decision tools to proactively manage livestock grazing, fire and drought impacts, improve animal productivity and product quality based on predicted nutrient intake, forage dynamics and diet selection and develop management strategies to restore rangelands degraded by weeds and prevent weed invasions,” says the website. Acting Research Leader and Range Ecologist Lance Vermeire studies plant community response to summer fires,

post-fire grazing management, long-term livestock exclusion and the effect of fire on grasshoppers. Matt Rinella is the weed ecologist at the research station, and Kurt Reinhart is the soil ecologist. “Understanding the mechanisms controlling disturbance effects on rangelands and animal responses to alterations in the plant community will promote development of proactive management strategies for improved stability in rangelands and rangeland livestock production systems,” the website continues.
