Effects of Dietary Protein and Threonine Supply on in Vitro Liver Threonine Dehydrogenase Activity and Threonine Efficiency in Rat and Chicken (Report‪)‬

INTRODUCTION Threonine is an indispensable amino acid for mammals and birds. Threonine degradation means an irreversible loss of threonine and increases the metabolic requirement for this amino acid. A detailed knowledge of the metabolic factors controlling threonine metabolism (Rees et al., 2006; van der Sluis et al., 2009) is needed in order to increase the understanding of how to optimize threonine supply and to meet the physiological threonine requirement (Le Floc'h et al., 1994; Samadi and Liebert, 2007; Levesque et al., 2011).
