Dr. Les Hansen on crossbreeding - 2013 World Ag Expo in California

Crossbreeding Study - July 2019

Final results of the 10-year designed study of ProCROSS cows versus their Holstein herdmates

Unlike previous research on crossbreeding of dairy cattle, this 10-year study had controlled
and balanced enrollment of foundation cows, had a clear design, used high-ranking proven
A.I. bulls for all breeds (Holstein, Viking Red, and Montbeliarde), and had dedicated
recording of data by the high-performance participating herds

Crossbreeding Study - January 2016

Comparison of Montbeliarde × Holstein and Viking Red × Holstein crossbreds
with pure Holstein cows during first lactation in 8 commercial dairies in Minnesota

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.
