ANDERSON, R; BATH, G F; THOMPSON, P N and STADLER, M M. Oesophageal obstruction in Dorper ewes caused by impaction of a pelleted ration. J. S. Afr. Vet. Assoc. [online]. 2010, vol.81, n.2, pp. 118-120. ISSN 2224-9435.
Two adult Dorper ewes developed an oesophageal obstruction (choke) by consuming a pelleted ration. The history, clinical signs and method of treatment were recorded in each case. One case was treated surgically via rumenotomy and the other conservatively. Both ewes recovered uneventfully and no recurrence was observed. Reasons for the compaction of the pelleted ration in the oesophagus are discussed.
