Intramuscular fat (IMF) is critical pork meat quality; however, its content is relatively low in commercial pig breeds. The objective of this experiment was to investigate the difference in intramuscular adipogenesis between Mashen and Large White pigs. 12 male Mashen and Large White piglets (six in each breed) were used, and longissimus dorsi muscle was sampled for analysis. The results showed that back fat thickness (p < .01) and leaf fat weight (p < .05) were increased in Mashen pigs.

With exception of sterol regulatory element-binding protein 1, mRNA expression of other adipogenic markers, including Zinc finger protein 423 (p < .05), platelet-derived growth factor receptor a (p < .05), CCAAT enhancer binding protein b
