Cystic hyperplasia of the gall bladder in breeding ewes.
Reproduction in Finnish Landrace X Polled Dorset Horn ewes was accompanied by thickening of the wall of the gall bladder. The thickening was caused by hypertrophy of the epithelium, the presence of cysts, proliferation of blood vessels, glands and fibrous tissue in the lamina propria and hypertrophy of smooth muscle. The changes appeared to be initiated during pregnancy but to persist in a modified and chronic form in post-parturient animals.
