Summary and Implications
Feed efficiency and related production traits continue to be of high interest in the swine industry as feed prices continue to rise. Two lines of Yorkshire pigs have been developed at Iowa State University to study the causes and effects of increased feed efficiency. The goal of this project was to use these lines to evaluate the genetic basis of juvenile serum IGF-I concentration, which has been shownto be an early indicator of genetic potential for feed efficiency later in life.
