Bovine respiratory disease (BRD) is a common and costly health problem in beef and dairy cattle industries worldwide. It is a complex respiratory infection caused by a combination of viruses, bacteria, and environmental factors. BRD can lead to severe respiratory distress, reduced productivity, and even death in affected animals. Research in the field of bovine respiratory disease aims to better understand the pathogens involved, as well as to develop effective prevention and control strategies. This includes studying the immunological response of cattle to respiratory pathogens, identifying risk factors for disease transmission, and evaluating the efficacy of vaccines and treatments. Overall, research in bovine respiratory disease is crucial for improving animal welfare, reducing economic losses for farmers, and ensuring a sustainable and productive livestock industry.
