Project Type: Reimbursable

Start Date: Apr 15, 2011
End Date: Apr 14, 2014

Objective:
The objective of this project is to reduce the prevalence of bovine respiratory disease (BRD) through the use of genetic selection and best management practices to improve animal welfare and the economic sustainability of beef and dairy operations.

Approach:
Chromosomal regions will be identified that are associated with BRD by examining 3,000 beef and 3,000 dairy cattle using a multi-tiered genetic approach that includes genotyping arrays and pathway analysis. Economic studies will also be conducted to identify the economic loss associated with BRD in feedlot cattle, replacement dairy heifers, beef bulls and dairy calves. Extension activities will also include outreach and 4-H education.
