Background
It is often difficult to balance high growth rates in immature heifers whilst maintaining good health and immunity status. The heifer must be able to cope with the stressful demands of entering the milking herd.

Micro-nutrients can play an important role in ensuring health and immunity are strengthened. This balance 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 heifer. 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.
