Cobalt deficiency

Cobalt deficiency

The sheep on the left has a cobalt deficiency; the one on the right is normal. Sheep are more susceptible to cobalt deficiency than cattle, but the effects of severe deficiency are the same – emaciation and eventual death. Cobalt deficiency or bush sickness was first recognised as a problem on the pumice soils of the North Island. However, it can also occur on other soils after a period of farming.
