Effects of dietary valine/isoleucine ratio and slaughter weight on the composition of pork flavor precursors.

ABSTRACT: This study aimed to investigate the effects of dietary valine/isoleucine (V/I) ratio and slaughter weight on the profile of pork flavor precursors. Metabolomics and volatilomic profiling were performed on meat harvested from a 2 × 2 factorial feeding study. Thirty-six Duroc × Landrace × Yorkshire castrated male pigs with around 75 kg body weight (BW) were randomly allocated to two dietary treatments, involving V/I (1.23 and 2.60 at 75 to 100 kg BW, 1.24 and 2.39 at 100 to 135 kg BW for the normal dietary valine/isoleucine ratio defined N [V/I] and high dietary valine/isoleucine ratio defined H [V/I], respectively) and two slaughter weights (lower weight [LW] 100 kg and higher weight [HW] 130 kg). Each group consisted of six replicates of three pigs per replicate. The trial lasted for 63 d.
