Item Crossbred Genotype Admixture(2022-04-27) Heins, Bradley; Huson, Heather; Dechow, Chad; Azwan Jaafar, Mohd; hein0106@umn.edu; Heins, Bradley; University of Minnesota West Central Research and Outreach Center Dairy HerdOur study evaluated two 3-breed rotational crossbred dairy cattle populations. ProCROSS is a product of crossbreeding Viking Red, Holstein, and Montbeliarde whereas Grazecross consists of Viking Red, Normande, and Jersey. The rotational crossbreeding system capitalizes on heterosis with each generation and the specific breeds used target trait improvement and development for certain environments.The effect of ancestry and use of reference populations in determining ancestry in ProCROSS and Grazecross were analyzed using genomic and pedigree-based estimations.Our study provides evidence of the importance of identifying the most appropriate reference animals and the effect of ancestry composition on ProCROSS and Grazecross dairy cattle performance.

Genetic data were used to assign strain ancestry from two stocked sources (from Minnesota and Wisconsin). Ancestry, sex and length were used as variables when examining movement patterns using an acoustic receiver array in the estuary and Lake Superior.
