Abstract: The objective of the experiment was to study the growth performance and meat quality of difference type pigs. 24 pigs of E-Xi (EX)black boars(Lard type), Landrace-York(LY) hybridized pigs(Bacon type) and Chang-Ye-E(CYE) boars(Meat type) respectively about 50 kg were raised to 100 kg and then 6 pigs each species were slaughtered to analyze the growth performance, carcass traits and meat quality. The results showed that the growth performance of LY pigs was higher than that of EX boars(P<0.05), and had a insignificant difference with CYE boars. The undressing percentage, lean percentage and eye lean area of LY pigs were higher significantly than those of EX boars and CYE boars and feed/gain ratio and backfat thickness were lower that EX boars(P<0.05).The meat pH2, drop loss and shear force of LY pigs were higher significantly than those of EX boars and meat color was lower than EX boars. The meat quality of CYE boars had an insignificant difference with LY pigs and EX boars.
