Using Qianshaohua pig as the female parent and Landrace pig as the male parent, they grew through hybridization × Qian mother parent, then backcrossed with Qian Shaohua pig and boar to form Qian • Chang × The Xuefenghua pig, a new breed developed through the combination of Guizhou pig breeds and subsequent population breeding, has a lean meat percentage of 47.87%, which is 5.79 percentage points higher than the Guizhou Shaohua pigs lean meat percentage of 42.08%, and 56.13% lower than the Guizhou Sanyuan hybrid pigs lean meat percentage, which is 8.26 percentage points lower. The slaughter rate of Xuefenghua pigs is 75.22%, which is 3.96 percentage points higher than the slaughter rate of Qianshaohua pigs, which is 71.26%. The daily weight gain of Xuefenghua pig is 569.82g, which is 443.27g higher than that of Qianshaohua pig, an increase of 28.5%, with a significant difference (p<0.05). The feed to meat ratio of Xuefenghua pig is 3.11:1, which is 3.56:1 lower than that of Qianshaohua pig, a decrease of 12.6%. Xuefenghua pork has a pH of 6.42± 0.08, dripping loss of 2.54%± 0.4%, muscle shear force of 42.14 N± 2.53, marble grade score of 3.20± 0.37, meat color score of 3.2+0.27, and intramuscular fat content of 1.91% ± 0.2, indicating that Xuefenghua pork has good tenderness, flavor, and juiciness. In addition, Xuefenghua pork has a high content of essential amino acids and iron elements, making it a delicious and nutritious meat. And a brief description was given of the development plan for the Xuefeng Flower Pig industry in Dongkou County, providing reference for pig farming peers.
