Chronic diffuse diseases of the biliary tract, such as sporidesmin poisoning and fascioliasis, can cause atrophy of the left lobe in ruminants, probably as a result of the greater difficulty in maintaining adequate biliary drainage from this lobe, whose bile ducts are longer than those of the right one in these species.
