Integrating transcriptome and proteome profiles to compare carcass and meat quality traits between Songliao and Songlei black pigs.

ABSTRACT: With the ongoing upgrade in consumption patterns, the pork market is shifting from a focus on quantity to an emphasis on quality, demanding higher intramuscular fat content alongside maintained growth rates. Crossbreeding between the Chinese lean-type Songliao black pig and the high-quality local breed Leixiang pig allows rapid integration of parental superior traits, resulting in hybrid vigor that effectively improves pork quality, growth performance, and economic benefits. We conducted transcriptomic and 4D microDIA proteomic sequencing analyses on the longissimus dorsi muscle tissue from hybrid offspring of purebred Songliao black pigs and Songliao × Leixiang black pigs. Extensive phenotypic analyses were performed on Songliao black pigs and Songlei black pigs using multiple trai
