• Validating loci associated with bovine respiratory disease complex in pre‐weaned Holstein calves

    7 days ago - By Animal Genetics

    Summary
    Bovine respiratory disease is considered one of the most economically important diseases in the cattle industry. Ultimately, the selection of cattle that are less susceptible to disease will allow producers to reduce the prevalence of BRD and lessen its economic impact. The objective of this study was to validate previously identified loci associated with susceptibility to BRD in an independent population of 140 pre‐weaned Holstein calves from Wisconsin. Using the McGuirk health scoring system, calves were classified as either clinically affected with BRD or healthy. Additive...
