Bovine Respiratory Disease Complex (BRD) is a disease that results in 75 percent of cattle morbidity and 50 percent of cattle mortality in feedlot cattle, reported Washington State University Extension. As most producers, veterinarians and researchers know, the disease is often linked to transporting cattle, especially when they are young.
Unfortunately, the relationship between the disease and transportation is not so simple. Several studies conflict on how shipping effects the cattle, such as whether long distances make a difference or how often cattle are loaded and unloaded. It is also unknown whether it is the transportation itself or other factors that contribute to this disease.
There are several factors that could play into the stress on cattle during and before transporting. Some major problems an include commingling, loading and unloading often, extreme weather, metaphylaxis, age and others can be factors in the number of cattle that contract BRD.
Bovine Respiratory Disease Complex is a widespread problem for cattle owners that can lead to extreme economic devastation. By preventing BRD, producers can decrease the workload stress in treating the disease and relieve the economic distress. Producers can prevent BRD by carefully considering the stressfulness of transportation and managing them beforehand.
