The liver is a vital organ with many physiological functions, including secretion, storage, synthesis, and detoxification. Bacterial, viral, parasitic, metabolic, and toxic diseases affecting the liver are quite common in animals. This study used necropsy findings, photographs, and microscopic data from 114 animals (25 sheep, 10 goats, 4 mountain goats, 58 lambs, and 17goat kids) necropsied over a 1-year period between March 2024 and March 2025. Of the 114 necropsied animals, 25 (28.5%) had macroscopic liver lesions, and 45 (39%) had microscopic liver lesions. The most common macroscopic findings were liver parasites (8 animals) and hepatic lipidosis (6 animals), while microscopic findings included focal hepatitis (18 animals) and Kupffer cell activation (15 animals). Liver lesions were more common in adult animals than in young animals, and similarly, in sheep than in goats (p<0.05). In the assessment of macroscopic findings 57% were classified as infectious and 43% was non-infectious. However, this difference was not found to be statistically significant (p>0.05). In the light of the data obtained, it was concluded that liver pathologies are remarkably common in small ruminants, metabolic and parasitic diseases are more prominent, and microscopic lesions may be present in livers that do not show macroscopic findings.
