RESUMO

Following clinical observations carried out on numerous herds in different countries the authors show that many similarities exist between proteino-energetic malnutrition and some symptoms of copper, zinc or cobalt deficiencies in ruminants. The probable origin of such a relationship is highlighted and the possible use of trace element therapy in livestock under malnutrition conditions is discussed.
