Trace elements are natural minerals required in very small amounts by the body for various metabolic processes. Typically they are not stored well in the body, so need to be constantly ingested in tiny amounts. If the body is deficient, the metabolic processes will be adversely affected.
Copper is the main trace element where deficiency is likely to be an issue in deer. Cobalt, iodine and selenium deficiencies also occur but are much less common.
Information on Copper is available in a convenient DINZ Deer Fact sheet (October 2016). Download your own copy here >>
