The objective of this study was to evaluate the effect of markers developed in eight genes, located in a previously detected meat quality QTL region on SSC17, on growth, fat and meat quality traits collected in commercial pig populations of different genetic backgrounds. The genes had been previously mapped to SSC17 as part of a fine-mapping effort. Association analyses were conducted between each marker and the available phenotypic traits. Results showed that three genes (CTSZ, CSTF1 and C20orf43) were significantly associated with the growth traits. In addition, CTSZ also impacted on meat colour, with the less favourable genotype for growth being associated with darker meat. The differences observed between genotypes were substantial and may be of economic importance to pig producers. These markers may be useful for selecting for faster growth or improved meat quality.
本研究旨在评估位于先前检测到的 SSC17 肉质 QTL 区域内的 8 个基因的标记对不同遗传背景下商业猪群中生长、脂肪和肉质特性的影响。这些基因之前已被映射到 SSC17 作为精细映射的一部分。对每个标记与可用表型性状之间的关联分析表明，三个基因（CTSZ、CSTF1 和 C20orf43）与生长性状显著相关。此外，CTSZ 还影响肉色，生长有利基因型与较暗的肉色有关。观察到的基因型之间的差异很大，对养猪生产者可能具有经济重要性。这些标记可能对选择更快的生长或改善肉质有用。
