“…The basic chemical composition (water, dry matter, total protein and IMF) were quantified according to the methods of Hur et al . (). The water‐holding capacity was measured as drip loss: the sample was placed in a net surrounded by an inflated plastic bag and suspended for 24 h at 4°C after slaughtering according to Franco et al .…”

Crossbreeding is an effective method of improving the efficiency and profit of production in commercial pig operations. To understand the effect of crossbreeding on meat and nutrient quality, a combination including three purebred (Duroc, D; Landrace, L; Yorkshire, Y) and two crossbred pig lines (Landrace × Yorkshire, LY; Duroc × (Landrace × Yorkshire), DLY) frequently used internationally were studied. The results showed that meat from the LY and DLY crosses had lower values for lightness L24h∗, shear force and epinephrine and higher values for drip loss, C18:1, insulin, glucagon and monounsaturated fatty acids than D, L and Y pigs. Moreover, LY had higher values for post mortem pH and lower values for a* and b* than the purebreds. In contrast, DLY had lower values for pH and higher values for a* and b* than the purebreds. Meat quality-related gene analysis showed that the CAST, IGF2 and MC4R gene expression levels in the LY and DLY pigs were significantly higher than those in the D, L and Y pigs. These results indicate that crossbreeding can alter the meat quality, nutritive value, energy metabolism and gene expression of pigs. Future research should focus on microRNA expression and DNA methylation that regulate gene expression and thus affect the meat quality.

“…Superior taste leads to an increase in JNP demand with every passing day but less productivity and fertility made it difficult to sustain the demand 6 , 7 . Due to huge demand but less productivity intrusion of different breeds leads to diversion of industry focus on alternative economic viable options 8 , 9 . These imported pig breeds possessed the excellent genetic potential for high production and their growth have been reported to more than 0.5 kg of weight per day but limited with meat quality content 10 , 11 .…”

Pig as a food source serves daily dietary demand to a wide population around the world. Preference of meat depends on various factors with muscle play the central role. In this regards, selective breeding abled us to develop “Nanchukmacdon” a pig breeds with an enhanced variety of meat and high fertility rate. To identify genomic regions under selection we performed whole-genome resequencing, transcriptome, and whole-genome bisulfite sequencing from Nanchukmacdon muscles samples and used published data for three other breeds such as Landrace, Duroc, Jeju native pig and analyzed the functional characterization of candidate genes. In this study, we present a comprehensive approach to identify candidate genes by using multi-omics approaches. We performed two different methods XP-EHH, XP-CLR to identify traces of artificial selection for traits of economic importance. Moreover, RNAseq analysis was done to identify differentially expressed genes in the crossed breed population. Several genes (UGT8, ZGRF1, NDUFA10, EBF3, ELN, UBE2L6, NCALD, MELK, SERP2, GDPD5, and FHL2) were identified as selective sweep and differentially expressed in muscles related pathways. Furthermore, nucleotide diversity analysis revealed low genetic diversity in Nanchukmacdon for identified genes in comparison to related breeds and whole-genome bisulfite sequencing data shows the critical role of DNA methylation pattern in identified genes that leads to enhanced variety of meat. This work demonstrates a way to identify the molecular signature and lays a foundation for future genomic enabled pig breeding.

“…To overcome these issues, JNPs were crossbred with Berkshire pigs, as these are considered a breed suitable for meat production. Thus, practical breeding of JNPs was achieved by crossbreeding with Berkshire pigs (Hur et al, 2013;B.-W. Kim et al, 2011). Crossbred pigs of JNPs and Berkshire pigs exhibited improved meat quality; thus, this meat is highly popular among Korean consumers.…”
