Abstract

Necropsies are an integral part of health programs in cattle feeding operations. Multiple benefits include better methods of fine tuning prevention and treatment programs. Disease processes are made visible and can be used in the very important process of training cattle handling personnel. Efficient use of time is enhanced by practical necropsy procedures. Guidelines are provided for necropsy interpretation and differential processes. Necropsy tips include use of necropsies to evaluate vaccine effectiveness, evaluation of pneumonias as dynamic processes, recognition of different types of interstitial pneumonias, and clarification of relationships between acidosis and other digestive diseases. Diseases of the central nervous system can be differentiated through necropsy observations supplemented with judicious use of laboratory assistance.
