Abstract
This study was conducted to determine the effects of breed and sex on meat quality and sensory properties of the loin in three-way crossbred pigs: Landrace × Yorkshire × Duroc (LYD) and Landrace × Yorkshire × Woori black pig, as Korean native pig (LYW). Carcass traits did not differ by breed. Carcass weight and backfat thickness were higher in castrates than in gilts (p < 0.01). Fat content, cooking loss, and water-holding capacity were higher in LYW than LYD (p < 0.05). Redness and yellowness of the meat were higher in LYW than in LYD (p < 0.01). Further, LYW had lower pH and shear force than LYD (p < 0.001). Two sensory properties, color and flavor, were better in LYW than in LYD, and in gilts than in castrates (p < 0.05). However, other sensory traits did not differ by breed or sex. Capric acid (C10:0) was higher in LYD than LYW (p < 0.001). However, stearic acid (C18:0) and saturated fatty acid (SFA) contents were higher in LYW than LYD (p < 0.05). Eicosenoic acid (C20:2) and the n6/n3 ratio were higher in gilts than in castrates, whereas SFA content was higher in castrates than in gilts. These results suggest that certain physicochemical qualities of meat and sensory properties are improved in LYW as compared to LYD. This study provided basic data on meat quality of crossbred pigs with Woori black pig as a terminal sire.
