The importance of venous blood gas findings and clinical scores in calves with bovine respiratory disease complex

Aim: The aim of this study was to determine the effects of bacteriological factors in the etiology of Bovine Respiratory Disease Complex (BRD) on the clinical scores and blood gases. Materials and Methods: The animal material of the study consisted of 28 calves with BRD (experimental group) and 10 healthy calves (control group), aged between 60-120 days. Calves with BRD were divided into three sub-groups depending on the microbiological examination of the bronchoalveolar lavage fluid; Mannheimia haemolytica (n:6), Pasteurella multocida (n:10) and Mycoplasma bovis (n:12). All calves were scored based on the Wisconsin (WI) score system. Blood gases were measured in venous blood samples. Results: All clinical scores were found to be higher (p
