Multiomics transcriptome and metabolome insights into fat metabolism and meat quality in Songliao black pigs and Songlei crossbred pigs.

ABSTRACT:

Background

The rising demand for high-quality pork among consumers has driven interest in genetic improvement strategies. Crossbreeding is well known to influence carcass performance and meat quality; however, the molecular mechanisms underlying these effects are still poorly understood. In this study, the F1 generation of the Songlei Crossbred Pig (SL) was developed through crossing the Songliao Black Pig (male) (SS) and the Leixiang Pig (female) (LL). We integrated the transcriptomes and metabolomes of the longissimus dorsi (LD) muscle of SS and SL under identical conditions to identify key mechanisms regulating the quality of crossbred meat.

Results

Compared with those of SS, the slaughter weight, carcass weight, and dressing percentage of SL were significantly lower, but
