The accuracy of field diagnosis and key diagnostic findings in feedlot cattle diagnosed with acute interstitial pneumonia in southwest Kansas at the time of necropsy

Abstract

Acute interstitial pneumonia (AIP) is a non-infectious respiratory disease that affects the beef cattle industry and has been identified as one of the costliest diseases affecting feedlot cattle. Causative agents of AIP have been identified in grazing cattle; however, AIP cases in finishing feedlot cattle needs more research to identify and verify etiology, treatment options, and further define causative agents. The objectives of this study were to determine the accuracy of field diagnosis of AIP, determine the histological and infectious profiles of multiple organs of AIP affected cattle, and to define the production status and physical characteristics of AIP affected cattle.
