Mostly supplemented for cattle, in most cases our problems with copper are 'secondary'. With adequate copper in the forage, it is the interactions with other minerals in the rumen (sulphur, iron, molybdenum) and in the body (molybdenum) that can mean that little, if any, copper is available.

Copper is stored in the liver, and released to maintain blood/tissue levels at a steady state. This means that measuring blood levels only can give a misguided interpretation of the animal's status.

We recommend that animals have liver samples tested, usually in the autumn, for a full picture of the animals copper status.
