Abstract

In conventional group-phase-feeding systems, all pigs receive the same feed during long periods and therefore, to express their growth potential, most of the pigs receive more nutrients than they need. In precision feeding systems, pigs are fed with diets tailored daily to its individual nutrient requirements. Optimal amino acid ratios have been stablished for conventional phase-feeding systems but these optimal ratios may differ between conventional and precision feeding pig production systems. In this way, the aims of this project are to review the ideal amino acid profile concept, to evaluate the impact of experimental errors in the estimation of amino acid utilization efficiency and the adequacy and limitations of actual experimental approaches used to estimate the optimal amino acid requirement and amino acid ratios in growing domestic animals. And to compare optimal threonine/lysine amino acid ratio between conventional group phase-feeding and individual precision feeding systems. (AU)
