AbstractTo investigate theeffectsof different dietary inclusion rates of fermented feed on production performance，meat qualityand immune indices of finishing pigs，a total of 2OO healthy DurocXLandraceXYorkshire （DLY） crossbred finishing pigs aged 10O days were randomly divided into 4 groups using arandom number table， with 5 replicates per group and 1O pigs per replicate： the control group （basal diet）， group A （ 95% basal diet + 5% fermented feed）， group B（ 90% basal diet + （24 10% fermented feed），and group C （ 85% basal diet + （20 15% fermented feed）.After a 60- dayfeeding trial，growth performance indices including average dailygain，slaughter performance including dressing percentage and lean meat percentage，meat quality indices including pHand shear force，and immune indices such as immunoglobulin IgG were measured.The results showed that compared with the control group，groups A，B and C presented significantly increased average daily gain，average daily feed intake，dressing percentage，lean meat percentage，loin eye area，carcassdiagonal length，pHat24 h post-mortem，andserumcontents ofIgG，IgAand IgM（ P< 0.05），whilethefeed-to-gainratio，backfatthickness，shearforce，cooking lossanddriplosswere significantlyreduced （ P <0.05）;theabove indices （except average daily feed intake）in group Cdifferedsignificantly from those in groups A and B（ P <0.05）.Collectively，dietary supplementation with fermented feed could effectively improve thegrowth performance，slaughter performance，meat quality and immune function of finishing pigs in a dose-dependent manner， and under the conditions of this experiment，the inclusion of 15% fermented feed in the basal diet of finishing pigs achieved the best regulatory effect.
