FEEDING THE MODERN GENOTYPE - TRACE ELEMENTS
J.A. Taylor-Pickard

Abstract
Trace mineral nutrition has until recently been a neglected area in pig nutrition. There is scant and incomplete information concerning the mineral requirements of modern genotypes with high levels of productivity. Consequently, many minerals are used at higher inclusion levels, such as zinc and copper in weaner rations to improve growth and reduce digestive disturbances post-weaning. Traditionally, inorganic minerals have been added to pig rations. Recently, there has been increased interest in the role of organic minerals which are more bioavailable and better meet the requirements of the modern genotype. In many circumstances, inclusion levels can be reduced through the use of organic minerals further reducing excretion levels. Not only does this improve efficiency, but also the health and welfare of the animal whilst better meeting environment requirements.
