Bezoars are solid structures found in the gastrointestinal tract, they are formed by aggregation of non-digestible material resulting from repeated ingestion, may having a nucleus hair or fur. Causing signs presented of obstructive processes, intussusception, enteropathies and perforations, generally, their signs are nonspecific and depends on the location and degree of obstruction. Thus, the present work aims to report the presence of a gastric trichobezoar in a specimen of collared peccary (Pecari tajacu) raised in captivity.
