The goals are to enhance disease resistance in pasture based dairy cattle through the adoption of optimal genomic selection and crossbreeding strategies and to understand the relationship of genotype and grazing behavior. At the Univeristy of Minnesota, West Central Research and Outreach Center, we will establish associations of produciton, fertility, disease, and health of pastured dairy calves and cowswith genomic predictions of disease resistance, breed composition, and dam A2 genotype. The incidence of respiratory disease in organic dairy calves and effects of respiratory disease on future performance will be determined. We will also evaluate the influence of genetic merit and breed composition on pasture behavior and fly infestation.
