The Coastal Creole pigs in Argentina are predominantly found in the wild and can trace their lineage directly back to the Iberian breeds introduced by Spanish colonizers. They currently stand as the sole Creole breed in the country recognized by the FAO. However, there exists a dearth of studies assessing their genetic potential within the swine industry. Therefore, this study aimed to genetically characterize the meat quality of Coastal Creole pigs based on seven single nucleotide polymorphisms (SNPs) within the Ryr1, PRKAG3, MC4R, H-FABP, and CAST genes. A total of N = 158 samples were collected from specimens distributed along the coastal region. Our findings revealed all loci to exhibit polymorphism, underscoring the population's remarkable genetic diversity. Furthermore, a higher frequency of alleles favorable for the PRKAG3, MC4R, CAST, and Ryr1 genes was observed, while alleles unfavorable predominated for H-FABP and CAST. The results obtained in this research are highly encouraging, reflecting the genetic potential of these pigs to be utilized in swine production programs.
阿根廷沿海克里奥尔猪主要生活在野外，可以直接追溯到西班牙殖民者引入的伊比利亚品种。它们目前是该国唯一被粮农组织认可的克里奥尔猪品种。然而，关于评估其在养猪业中的遗传潜力的研究还很少。因此，本研究旨在基于 Ryr1、PRKAG3、MC4R、H-FABP 和 CAST 基因中的七个单核苷酸多态性 (SNP) 对沿海克里奥尔猪的肉质进行遗传特征分析。总共从分布在沿海地区的标本中收集了 N = 158 个样本。我们的研究结果表明所有基因座都存在多态性，突显了该种群显著的遗传多样性。此外，观察到 PRKAG3、MC4R、CAST 和 Ryr1 基因的有利等位基因频率较高，而 H-FABP 和 CAST 基因的不利等位基因占主导地位。本研究的结果非常令人鼓舞，反映了这些猪在猪生产计划中的遗传潜力。
