Bovine Respiratory Disease Complex
Fluctuating temperatures and wet weather have brought some devastating respiratory outbreaks to our area. While bovine respiratory disease complex (BRDC) is caused by a combination of viruses and bacteria, stress is an important part of the disease process as well. Stress suppresses the immune system and creates an opportunity for pathogens to cause disease. There are many causes of stress including shipping, commingling groups, weaning, weather fluctuations and feed changes.
