Background
It is often difficult to balance high productivity with high herd health status. Micro-nutrients can play an important role in ensuring herd health and immunity are strengthened. This balanced supply is often difficult to achieve with conventional feedstuffs/minerals.

Research work has shown that organically chelated trace elements, where the mineral is bonded to an essential amino acid, can improve utilisation by the cow. Trace element imbalances can either be naturally ocurring or induced. The 'lock-up' of trace elements by heavy metals may lead to metabolic, immunity or production disorders.
