UNASSIGNED: Forty entire male @entity1707 from a commercial crossbreed (Duroc * Large White * Landrace) were used to investigate the individual or combined effects of @entity7727 and @entity534 supplementation in Lys-deficient diets on growth performance, carcass traits, and pork quality. @entity1707 with 59.9    1.65 kg BW were randomly assigned to 1 of 5 dietary treatments ( = 8). The 5 dietary treatments were normal Lys and CP diet (0.51% Lys and 16% CP; control), reduced Lys and CP diet (0.35% Lys and 13% CP), reduced Lys and CP diet with @entity7727 supplementation (0.33%), reduced Lys and CP diet with @entity534 supplementation (1.5%), and reduced Lys and CP diet with @entity7727 and @entity534 supplementation (0.33% @entity7727 and 1.5% @entity534 ). @entity1707 were slaughtered at 92.7    2.54 kg BW. The Lys-deficient diets (-35% Lys) increased intramuscular fat (IMF) content by 25% ( = 0.041) and meat juiciness by 12% ( = 0.041) but had a negative effect on growth performance ( < 0.05) of @entity1707 . In addition, Lys-deficient diets increased L* ( = 0.005) and b* ( = 0.010) muscle color parameters and perirenal fat deposition ( < 0.001) and decreased both HCW ( = 0.015) and loin weight ( = 0.023). @entity7727 and @entity534 supplementation of Lys-deficient diets had no effect on IMF content but increased ( < 0.05) overall pork acceptability. @entity369 supplementation also increased ( = 0.003) meat tenderness. Differences in @entity844 composition of pork were not detected among dietary treatment groups. However, @entity3952 was positively correlated ( < 0.05) with IMF content, juiciness, flavor, and overall acceptability of meat. Data confirm that dietary CP reduction enhances pork eating quality but negatively affects @entity1707 ' growth performance. Moreover, it is suggested that @entity7727 and @entity534 supplementation of Lys-deficient diets does not further increase IMF content but improves some pork sensory traits, including overall acceptability.
