Respiratory Pathogens in Québec Dairy Calves and Their Relationship with Clinical Status, Lung Consolidation, and Average Daily Gain 2015-01-25 .txt text/plain 4657 268 57 OBJECTIVES: To identify the main respiratory pathogens isolated from calves in Québec dairy herds with a high incidence of BRD, and to determine if there is an association between the presence of these pathogens and clinical signs of pneumonia, lung consolidation, or average daily gain. Therefore, the first objective of this study was to identify the main respiratory pathogens found in preweaned dairy calves from herds with a high prevalence of BRD. The current study focuses on the prevalence of microbial pathogens in cases of BRD in preweaned dairy calves in relatively small herds using an objective measure (lung consolidation) for the definition of cases of BRD in living animals. Mycoplasma bovis was the third most frequently found bacteria in the current study, but it was the only 1 associated with clinical score, lung consolidation, and poor subsequent ADG. ./cache/cord-348829-87bvym6i.txt ./txt/cord-348829-87bvym6i.txt
