Porcine Tail Biting Study Guide

Overview and Clinical Importance

Tail biting is an abnormal, damaging behavior where pigs orally manipulate, chew, or bite the tails of pen mates, resulting in tissue damage ranging from mild lesions to complete tail loss. This behavioral disorder is one of the most significant welfare and economic problems in modern commercial swine production, particularly affecting intensively housed grower-finisher pigs.

Tail biting has a multifactorial etiology, involving complex interactions between environmental, nutritional, social, and individual pig factors. Understanding this condition is essential for NAVLE candidates as it encompasses principles of animal welfare, behavioral medicine, herd health management, and wound management.

Types of Tail Biting Behavior

Research has identified three distinct behavioral patterns of tail biting, each with different motivational drivers, clinical presentations, and management implications. Understanding these types is critical for implementing targeted interventions.
