Feedlot Diagnostics and Common Sense

Abstract

Approaches to feedlot diagnostics continually change as new information becomes available to managers, veterinarians and diagnosticians. Record keeping has evolved to a point where considerable precise information regarding performance, demographics and health issues can be quickly generated. Diagnostic laboratories continue to develop more precise techniques for detecting pathogens, deficiencies and tissue damage. The role of the attending veterinarian becomes more challenging and demanding because production costs and performance issues dictate the need for better health performance. Only the on-site veterinarian can provide the skill needed to decide what information is needed and to assimilate that information into useful decision-making. Sensitive and specific diagnostic tests must be viewed with perspective to avoid being misled into over-interpreting diagnostic information.
