“…The average number of stillborn piglets in litters of crossbred Landrace × Yorkshire sows in five herds (Denmark) ranged from 1.0 to 2.3 piglets per litter (Schild et al, 2019). The proportion of stillborn piglets in the litter was most often in the range of 4% to 10% (Roongsitthichai & Olanratmanee, 2021), although cases are known where this estimate reached 19% or more (Langendijk & Plush, 2019). Thus, the obtained estimates of the average number and proportion of stillborn piglets in the litters of UMB sows in the studied herd (1.2 piglets and 10.5%, respectively) fall within the values previously noted for highly productive pig herds from different countries worldwide.…”

In the livestock industry, the growth and fatness traits are directly related to production efficiency and economic profits. As for Diannan small-ear (DSE) pigs, a unique indigenous breed, the genetic architecture of growth and fatness traits is still elusive. The aim of this study was to search the genetic loci and candidate genes associated with phenotypic traits in DSE pigs using GWAS based on the Geneseek Porcine 50K SNP Chip data. A total of 22,146 single nucleotide polymorphisms (SNPs) were detected in 265 DSE pigs and used for Genome-wide association studies (GWAS) analysis. Seven SNPs were found to be associated with back height, chest circumference, cannon bone circumference, and backfat thickness at the suggestive significance level. Based on gene annotation results, these seven SNPs were, respectively, mapped to the following candidate genes, VIPR2, SLC10A2, NUCKS1, MCT1, CHCHD3, SMOX, and GPR1, which are mainly involved with adipocyte differentiation, lipid metabolism, skeletal muscle development, and average daily weight gain. Our work offers novel insights into the genetic architecture of economically important traits in swine and may play an important role in breeding using molecular markers in the DSE breed.

“…According to the method applied in previous research [39], six body measurement traits were measured by a tape or a meter ruler. The A-mode ultrasonography (Renco lean meter®, Minneapolis, MN, USA) was used to determine BF at 3rd and 4th last ribs (near the dorsal midline at 5 centimeters) [40]. BW was recorded by weighing scale.…”

Background: In the livestock industry, the growth and fatness traits are directly related to production efficiency and economic profits. As for Diannan small-ear (DSE) pigs, a unique indigenous breed, the genetic architecture of growth and fatness traits are still elusive. The aim of this study was to search the genetic loci and candidate genes associated with phenotypic traits in DSE pigs using GWAS based on the Geneseek Porcine 50K SNP Chip data. Results: A total of 30,648 single nucleotide polymorphisms (SNPs) were detected in 265 DSE pigs. After filtering, 22,146 SNPs were used for Genome-wide association studies (GWAS) analysis. The significant phenotypic correlations among eight important growth traits (body weight, back-fat thickness, and six body measurement traits) were observed. Seven SNPs surpassing the suggestively significant threshold for back height, backfat thickness, chest circumference and cannon bone circumference. Based on gene annotation results, these seven SNPs were mapped to the following candidate genes, VIPR2, SLC10A2, NUCKS1, MCT1, CHCHD3, SMOX and GPR1, which are mainly involved with adipocyte differentiation, lipid metabolism, skeletal muscle development, and average daily weight gain. Conclusions: Our work offers novel insights into the genetic architecture of swine important economic traits and may play an important role in molecular markers breeding for DSE pig.
