Dr. Ken Stalder has established a national and international reputation in the area of genetics of sow longevity. His research program has focused on the economic value of sow longevity, on management factors leading to early culling of sows, and on the genetic factors that contribute to sows having a long and productive lifetime in the breeding herd. Dr. Stalder was one of the first researchers to bring this trait to the forefront. Today, virtually all swine genetics companies and swine production systems recognize the value of sow longevity and incorporate this trait in their programs. Dr. Stalder has seamlessly integrated his research, extension and teaching programs, which is a model used by specialists nationally. Dr. Stalder has demonstrated a unique ability to develop sound applied genetics research programs that address producer’s everyday problems. The acceptance of his recommendations throughout the U.S. and globally have confirmed the value of his contributions.
