Low Copper Levels Associated with Low Carcass Weight in Wild Red Deer ( Cervus elaphus ) in Norway.

Copper (Cu) deficiency is associated with several disease syndromes, including poor growth, in farmed red deer ( Cervus elaphus ), but little is known of the consequences of low Cu levels in free-ranging populations. Low hepatic Cu levels have been documented in several wild red deer populations along the west coast of Norway, with the lowest values found on the island of Hitra. We studied the relationship between liver Cu concentration and slaughter weight in 63 red deer calves and 69 yearlings shot on Hitra during the autumn hunting season of 2009.
