“…Recently, the meat quality of the hybrid KNP was improved by crossing with the Landrace (LR) variety [4]. Since 1960, Western breeds have been imported, marginalizing KNP in commercial meat markets due to their comparatively lower growth rates and reproductive capacity (despite their desirable sensory traits) [5,6]. In 2008, although KNP were established as purebreds and formally approved for sale at meat markets, a black-coated pig (actually a cross with Berkshire (BS) pigs) erroneously labeled as KNP was distributed, often illegally [7].…”

The Korean native pig (KNP; Sus scrofa coreanus) is an indigenous porcine breed in South Korea considered as a valuable but dwindling genetic resource. Studies using diverse methodologies and genetic markers suggest that this population originated from the Manchu province of Northeastern China and migrated approximately 3000 years ago into the Korean peninsula. This study aimed to verify those findings by performing diversity and ancestral analyses using the 60K single-nucleotide polymorphism (SNP) BeadChip on 891 pigs of 47 breeds worldwide. We also performed principal component analysis (PCA), ancestry analyses, phylogenetic tree analysis using SNPhylo, and linkage disequilibrium analysis. Furthermore, we generated heatmap, obtained Nei’s genetic distance and FST values, and explored the heterozygosity of commercial and native Korean pigs. The results demonstrated that KNP pigs are more closely related to European breeds than to Chinese breeds. In addition, as previous studies have suggested, our admixture analyses indicated that KNP pigs showed distinguishable genetic structure.

“…However, they also have poorer productivities, such as lower growth rates and litters per sow per year than typical imported breeds, such as Duroc and Yorkshire. 8 , 9 Since the beginning of the last century, the native breeds have been endangered, especially because of the extensive crossbreeding with economically promising imported breeds. To conserve the native genetic resource, recent efforts have been made by the National Institute of Animal Science (NIAS) in Korea to restore and manage the Korean native population.…”

Pigs have been one of the most important sources of meat for humans, and their productivity has been substantially improved by recent strong selection. Here, we present whole-genome resequencing analyses of 55 pigs of five breeds representing Korean native pigs, wild boar and three European origin breeds. 1,673.1 Gb of sequence reads were mapped to the Swine reference assembly, covering ∼99.2% of the reference genome, at an average of ∼11.7-fold coverage. We detected 20,123,573 single-nucleotide polymorphisms (SNPs), of which 25.5% were novel. We extracted 35,458 of non-synonymous SNPs in 9,904 genes, which may contribute to traits of interest. The whole SNP sets were further used to access the population structures of the breeds, using multiple methodologies, including phylogenetic, similarity matrix, and population structure analysis. They showed clear population clusters with respect to each breed. Furthermore, we scanned the whole genomes to identify signatures of selection throughout the genome. The result revealed several promising loci that might underlie economically important traits in pigs, such as the CLDN1 and TWIST1 genes. These discoveries provide useful genomic information for further study of the discrete genetic mechanisms associated with economically important traits in pigs.

This study was conducted to develop new crossbred pig using Korean native pig and Duroc. Fifteen pigs of pure Duroc (D) and 26 crossbred gilts (15 of DK1 and 11 of DK2) were reared until 195 ± 5 days old, then slaughtered at local slaughterhouse. Pork loin was gathered and vacuum packed from left carcass after 24 h of slaughter to analyze meat quality traits, such as color, pH, water holding capacity (WHC), cooking loss and shear force (SF), and free fatty acid composition. Live weight and carcass weight of Duroc and DK1 were 119.1±8.7 / 82.91±6.1kg and 116.3±6.3 / 80.91±4.4 kg, respectively, and it was significantly higher than those of DK2 (104.7±8.4 / 71.36±5.7 kg) (p<0.05).There was no significant difference in proximate composition between animal groups, however DK2 showed significantly lower shear force (SF) and higher water holding capacity (WHC) than other groups (p<0.05). The redness of DK2 also showed significantly higher than Duroc (p<0.05), however there was no significant difference in lightness and yellowness (p>0.05). DK1 showed the highest monounsaturated fatty acids (MUFAs) contents of 51.45±2.0% and DK2 showed the highest polyunsaturated fatty acids (PUFAs) contents of 8.98±1.4%, however there was no significantly difference in PUFA/SFA ratio between pig groups (p>0.05). Duroc and DK2 contain significantly higher amount of linoleic (7.99±1.2 and 8.11±1.3%, respectively) and linolenic acid (0.43±0.1 and 0.44±0.1%, respectively) than DK1, and DK1 contains significantly higher amount of oleic acid (47.32±1.8%) than others (p<0.05).
