Abstract: The specialized dam line with high farrowing rate of Shanxi White pig (SXWSDL) is a synthetic line produced by crossing Mashen pig, Taihu pig (female parents) with Landrace (male parent) and selecting by means of combining the marker assisted selection with systematic breeding from generation to generation for seven years. The finishing performance and carcass quality of Shanxi White pig were investigated in this study. The results showed that the age of pigs from sixth generation of Shanxi White pig reaching 100 kg body weight was 186.48 days on average. The average daily gain during the period of 30 to 100 kg was 708.35 g, and the feed conversion rate was 3.14. The pigs were slaughtered while its body weight was 100 kg. The slaughter rate, the carcass lean meat percentage, and the area of eye muscle were 77.00%, 57.93%, and 32.20 cm2, respectively. Shanxi White pig is a good dam line with fast growth rate and good carcass quality.
