Ivan, M. Hidiroglou, S. Al-Ismaily, H. Al-Sumry, R. Harper] Carence En Cuivre Dans Le Sultanat D'Oman Summary: A posterior ataxia or paralysis in goats and sheep is a syndrome known as Shalal within the Sultanate of Oman. An investigation was carried out into the etiology of the syndrome. Samples of blood and tissues were obtained from normal and Shalal-affected goats and sheep. Samples of feed were collected from the affected areas of the Sultanate. Chemical analyses of samples showed that affected animals suffered from severe copper deficiency in spite of sufficient copper contents in feed. However, concentrations of sulphur and iron in the feed were high. It was concluded that the Shalal syndrome in Oman is the condition generally known as swayback or enzootic ataxia caused by conditioned copper deficiency. The deficiency is probably due to copper-sulphur and copper-iron interactions in the rumen, enhanced by feeding of fresh roughage containing rumen degradable proteins.
