The documented decline of health, fertility, and survival of pure Holsteins has resulted in tremendous global interest in crossbreeding of dairy cattle. Monitoring of genetic relationships and inbreeding of Holsteins has been an on-going area of interest for researcher Dr. Les Hansen. The majority of Dr. Hansen's research at the University of Minnesota currently is focused on the comparison of crossbreds versus pure Holsteins.
