Abstract

OBJECTIVE: To describe the steps of performing a liver biopsy in cattle. ANIMALS: Beef and dairy cattle. METHODS: The video describes and demonstrates the steps of performing a standing percutaneous liver biopsy in cattle. Sample collection and handling are covered, and the purpose for liver biopsy collection in cattle is outlined. RESULTS: Ultrasound is used to identify location in a dairy cow. The video demonstrates the use of a manual biopsy tool and covers the purpose of liver biopsy as well as sample handling. CLINICAL RELEVANCE: Liver biopsy is a common diagnostic technique used for both histopathology and mineral analysis. This technique is not commonly taught in veterinary school but is an important tool for herd health management.
