Testing Frequency and Results of Cases of Feedlot Cattle Submitted to Kansas State University Veterinary Diagnostic Lab for Bovine Respiratory Disease

Bovine respiratory disease (BRD) is a multifactorial disease of cattle that results in large economic losses to the cattle industry. BRD results from various factors leading to susceptibility of cattle to respiratory tract infection by one or more bacterial and viral pathogens. These pathogens include M. haemolytica, H.somni, P multocida, Pseudomonas spp, A. pyogenes, Mycoplasma bovis, bovine coronavirus, BRSV, BVDV, IBR and PI-3. The purpose of this study was to determine the frequency in which type of diagnostic tests were being requested by practitioners for BRD submissions and the results of these tests.
