Abstract Copper Cu deficiency was diagnosed in a Norwegian red deer Cervus elaphus herd subsequent to deaths due to emaciation in late autumn 1999. The animals had free access to salt licks containing 3000 mg Cu kg. An evaluation of the herd revealed poor calf growth rate low weights of adult hinds dull and light-coloured hair coats and cases of diarrhoea. The herd was subsequently monitored throughout a three-year period of Cu-supplementation. The monitoring regimen included clinical observation copper serum examination weighing faecal parasitological examination and reproduction control by ultrasound. During the period January 2000 to May 2001 the animals were treated with Cu oxid capsules 1 g CuO 10 kg liveweight at 2-4 months intervals with the exception of March to September 2000. The animals were fed .
