Abstract

In this study, meat quality traits were compared between Chinese lard- and European lean-type pigs. The association between expression of four genes (ADSL, GARS-AIRS-GART, DGAT1, and DECR1) and meat quality traits was also investigated. Meat quality traits were found to differ significantly between pig breeds. Meat color parameter values (a* and b*) and intramuscular fat content in Anqingliubai were significantly higher than those in Landrace (P < 0.01). Meat pH at 1 and 24 h following slaughter was significantly higher in Landrace than in Wei pigs, and meat inosine monophosphate (IMP) content was significantly higher in Landrace than in Wei and Anqingliubai pigs (both P < 0.01). Expression levels of ADSL, GARS-AIRS-GART, and DGAT1 were higher in longissimus lumborum muscle than in heart or liver tissues. ADSL and GARS-AIRS-GART expression levels were correlated with meat IMP content and pH levels. The results of this study will contribute to the understanding of meat quality traits in Chinese lard- and European lean-type pigs.
