Summary

A trial was conducted using 134 pigs from weaning (21 kg) to finishing (105 kg) fed wheat-soy based commercial feeds formulated with either inorganic minerals or lower levels of organic (chelated) forms. Pigs fed the organic mineral diet has significantly higher (P < 0.05) average daily gain (ADG) compared to those receiving the inorganic control diet between day 31 and 64 of the trial period. The pigs receiving the organic minerals yielded 2 kg extra carcass weight, higher slaughter efficiency (P < 0.05) and greater ham width (P < 0.05). Economic benefits resulted for the organic mineral diets, due to improved performance and reduced mineral inclusion.
