Transcriptome sequencing of the longissimus dorsi in sheep

Crossbreeding improves and enhances meat quality and is widely used in sheep production; however, the molecular mechanisms underlying the meat quality of various crossbred sheep remain unknown. In this study, male Southdown, Suffolk and Hu sheep were crossbred with female Hu sheep, and the transcriptomes of the longissimus dorsi muscle of the F1 generation were sequenced to explore how different sire breeds affect meat quality.
