Brian Kirkpatrick is a Professor in the Department of Animal and Dairy Sciences whose research and instructional activities related to genetics and genomics of livestock. Dr. Kirkpatrick’s research activities focus on understanding the genetic basis for variation in health and reproduction in both beef and dairy cattle. Within these areas, the genetics of host susceptibility to infection by Mycobacterium avium subspecies paratuberculosis, the cause of Johne’s disease, and genetics of ovulation rate and twinning rate are specific emphases.
