Thirty-six uncastrated male lambs (90 old) were fed experimental diets, which treatments consisted of 0%, 1%, 2%, and 4% inclusion of YME. Animals were fed for 50 d before slaughter. Muscle and meat samples were collected for metabolomics and meat quality analysis, respectively. The experiment was carried out in a randomized block design and analyzed using orthogonal contrasts. There was a quadratic effect of YME inclusion in tenderness (P &lt 0.05) and a positive linear effect on meat lightness (P &lt 0.05). No qualitative changes (P &gt 0.05) on individual metabolites were observed; however, changes in the qualitative metabolic profile were observed, showing that animals fed 1% and 2% of YME have a greater concentration of desirable endogenous muscle antioxidants, with direct impact on metabolic pathways related to beta-alanine metabolism and glutathione metabolism. Therefore, YME dietary supplementation up to 2% of the diet to lambs had little to no effects on the majority of meat quality traits evaluated; moreover, 4% of YME, inclusion negatively affected feed intake and meat quality traits.  aInstrumental meat quality  aNatural additive  aTenderness1 aCORREIA, B.
