Abstract
A case of oviductal volvulus, a rare disorder with oviductal cyst as a possible aetiology, is described in an 11-month-old Nera black chicken (Gallus gallus domesticus). The condition was observed during routine postmortem
examination of 550 carcasses from a flock of 16 100 birds between September 2005 and June 2006. The affected portion of the oviduct and the cyst twisted almost 360° clockwise around the dorsal ligament with severe congestion, hyperaemia, oedema, dilatation and devitalization. This is the first reported case of oviductal volvulus in a domestic chicken.
