In the present prospective study from August 2016 to July 2017 a total of 117 pneumonic goats were screened, of which naturally infected twenty-four cases of bacterial pneumonia were evaluated for pulmonary function in detail based on the different diagnostic methods such as clinical examination, isolation and identification of bacteria, hematology, blood gas analysis and radiographic study. Predominant clinical signs such as pyrexia, coughing, sneezing, congested mucous membrane, tachypnoea and bilateral nasal discharge noticed which are considered to be major indicator of bacterial pneumonia. Isolation and identification of bacteria confirmed that Pasteurella spp. () as predominant bacterial isolate followed by Mannheimia spp., Pseudomonas spp., Escherichia spp., Staphylococcus spp. and Bacillus spp. The hematology and blood gas analysis revealed significant leucocytosis with neutrophilia indicating acute bacterial infection whereas increased VpCO2, VtCO2, H+ ions and decreased VpO2, VO2 sat values were suggestive of respiratory acidosis leading to severe respiratory distress. Further radiography of thoracic region in pneumonic goats helped in assessing its severity of pulmonary function as score-1, 2 and 3. The results concluded that above diagnostic methods aids in knowing the severity and prognosis of bacterial pneumonia in goats. | Evaluation of pulmonary function in goats affected with bacterial pneumonia
