Effects of Dietary Low Level of Threonine and Lysine on the Accumulation of Intramuscular Fat in Porcine Muscle

Abstract

We attempted to determine whether shortage of dietary threonine enhances the accumulation of intramuscular fat (IMF) in porcine muscle. Although dietary low levels of lysine enhanced the concentration of IMF in the longissimus dorsi and rhomboideus muscles, dietary low threonine did not. We conclude that the effect of dietary threonine levels on the accumulation of IMF in porcine muscle is negligible.
