John Jaeger took over the beef research program at the Agricultural Research Center - Hays in January 2006. He had previously worked at the center from 1986 to 1994 as a research assistant and cow-calf herdsman.
He earned bachelor’s, master’s and doctoral degrees from Oregon State University. His expertise is in reproductive physiology. From 1994 to 2000, he worked as a research assistant and ranch manager at OSU’s Eastern Oregon Agricultural Research Center in Union, Ore.
Jaeger is particularly interested in cow-calf production systems that will result in a value-added beef carcass. Early weaning of calves may be a low-cost sustainable system that will reduce cow maintenance costs, as well as improve cow performance and carcass quality of offspring.
