Abstract

Infectious Bovine Rhinotracheitis (IBR), also called Nectrotic Rhinitis, Red Nose, and Dust Pneumonia, has been a major feedlot problem for more than a decade. The disease was first reported from Los Angeles county California in 1954 by Schroeder and Mays. Miller observed the disease in Colorado and described it at this time as an acute respiratory condition characterized by high fever and a severe dyspnea resulting from abundant mucopurelent nasal and tracheal secretions.
