This study aimed to investigate the expression profiles of the myogenic regulatory genes , and in as well as the correlation of the expression levels of these genes with carcass characteristics and growth performance in the Kivircik and Hungarian Merino sheep breeds. The expression levels of the and genes were found to be significantly correlated with the rib proportion, the expression level of the gene was identified as being the main determinant of variations in the rib proportion in the Kivircik lambs. The regression analysis results revealed that the expression levels of the and genes played an essential role in determining the cold carcass dressing percentage in Hungarian Merino lambs. Further, as a result of the regression analysis, the model including the expression level of the gene demonstrated that this gene could be responsible for 36.4% of the differences observed in cold carcass weight. In conclusion, the findings of this study suggest that the expression levels of the and genes were associated with various carcass traits, particularly in the Kivircik breed, and these genes hold potential as markers for enhancing breed productivity.
本研究旨在调查肌生成调节基因在基维里克羊和匈牙利美利奴羊品种中的表达谱，以及这些基因的表达水平与胴体特征和生长性能之间的相关性。发现MyoG和MyoD基因的表达水平与肋骨比例显著相关，MyoG基因的表达水平被确定为基维里克羔羊肋骨比例变化的主要决定因素。回归分析结果表明，MyoG和MyoD基因的表达水平在决定匈牙利美利奴羔羊冷胴体屠宰率方面起着重要作用。此外，回归分析结果显示，包含MyoG基因表达水平的模型表明，该基因可能导致冷胴体重差异的36.4%。总之，本研究结果表明，MyoG和MyoD基因的表达水平与各种胴体性状相关，特别是在基维里克品种中，这些基因具有作为提高品种生产力标记的潜力。
