title: Copper deficiency in ruminants in the Rift Valley of East Africa.
abstract: Enzootic ataxia of newborn domestic ruminants and particularly of small ruminants is a widespread disease often observed in East Africa. It is characterised by very low blood copper levels and sometimes by histological lesions characteristic of a severe copper deficiency. This disease observed and described by various authors in Kenya, Ethiopia and Djibouti seems to be closely associated with the pedogeological area of the Rift Valley. Climatic conditions and geo-morphological characteristics of this area, particularly the molybdenum and sulphur excess in this volcanic region, seem to account for the marked clinical signs of this mineral deficiency.
