Early administration of an effective antimicrobial at the appropriate dose is beneficial for the successful treatment of BRD-affected animals. When an outbreak of BRD is anticipated or present in a group of cattle, metaphylaxis (mass treatment) of the high-risk group with an antimicrobial can decrease BRD morbidity.
What is BRD caused by?
