Bovine respiratory disease (BRD) is the leading natural cause of death in beef and dairy cattle, causing annual losses of more than 1 million animals and $692 million. This disease complex includes a number of viruses and bacteria that are responsible for up to 50 percent of the cattle death in feedlots. An AFRI Coordinated Agricultural Project (AFRI-CAP) led by Texas A&M University is identifying genetic loci and genomic rearrangements associated with BRD and using these data to develop diagnostic tests and selection tools to identify BRD-resistant animals. Incorporating BRD into genetic evaluations and selection decisions offers a sustainable approach to reduce disease incidence.
