USING BEEF SEMEN TO BREED DAIRY COWS HAS CREATED CROSSBRED CALVES FOR THE FEEDLOT. HOWEVER, THE ECONOMIC EFFICIENCY OF THESE CALVES IN THE FEEDLOT AND AT SLAUGHTER HAS NOT BEEN DETERMINED. IN ADDITION, THE MOST OPTIMAL BEEF GENETICS TO USE WHEN BREEDING DAIRY COWS HAS NOT BEEN IDENTIFIED. THIS PROJECT AIMS TO IDENTIFY THE APPROPRIATE GENETICS TO USE WHEN BREEDING DAIRY COWS AND TO DETERMINE THE ECONOMIC ADVANTAGE OF USING THE SELECTED GENETICS. THE RESULTS OF THIS PROJECT WILL BE DISSEMINATED THROUGH EXTENSION VIDEOS AND PUBLICATIONS TO ASSIST AREA PRODUCERS IN BREEDING DECISIONS.
