Genetic isolation and identity in pigs of rassian and foreign populations
Abstract
Modern pig production balances between intensive farming using high-performance breeds (Landrace, Large White, Duroc) and the conservation of genetic diversity in native breeds such as the Hungarian Mangalica. This study aims to identify genomic differences between these groups using whole-genome genotyping (PorcineHD BeadChip, 66,763 SNPs) and analysis of genetic differentiation (Fst). Duroc vs. Mangalica: 67 SNPs and 118 genes, including AHI1 (embryonic development), APLP2 (backfat thickness), HECTD2 (meat quality), and VDAC1 (reproduction). A 97% similarity was found between the Large White and Mangalitsa breeds, with 228 genes identified, including MAPK4 (growth), RPAP3 (immunity), MGAT5 (intramuscular fat) and EXOC4 (nipple number). Between the Landrace and Mangalitsa breeds, 82% similarity was identified, 195 genes were found, including PTPRD (meat quality), ITGA9 (ASF resistance) and NCAM2 (offspring uniformity). The study contributes to the understanding of genetic mechanisms of phenotypic variability and offers tools for improving the efficiency of selection in pig production.
