Acute poisoning may follow intakes of 20–100 mg/kg of copper in sheep and young calves and of 200–800 mg/kg in mature cattle. The “copper to molybdenum” ratio may be used to identify a secondary deficiency of molybdenum in copper toxicity. Excessive intake of molybdenum causes a physiological copper deficiency, and conversely, in cases of inadequate dietary intake of copper, molybdenum toxicity may occur at lower exposure levels. and muscle pain, weight loss, red and moist skin, tremor of the hands, sweating, and dizziness were reported
