Interpretation of blood copper results
Supplementation on a group basis can be justified where the mean of a representative number of animals from the group (at least six and at least 10 from groups >60) falls beneath the 'marginal status' band of 3.0 to 8.0 umol/l (serum copper). Where the mean falls within the 'marginal status' band there may or may not be a response to supplementation. On an individual animal basis values beneath the 'marginal status' band are suggestive of production limiting dysfunction.
These points are valid for animals >1 week of age fed diets containing less than 8mg/kg DM molybdenum(sheep, goat & deer) or 15mg/kg molybdenum (cattle). Note that stimulation of the immune system (vaccination or infection) can falsely elevate copper results due to elevation in acute phase proteins.
