The slaughter value of live cattle can be assessed during visual conformation scoring, as well as by examining different molecular genetic information, e.g., the gene, which can be responsible for muscle development. In this study, the , , , and alleles of the gene () were examined in relation to birth weight (BIW), calving ease (CAE), 205-day weaning weight (CWW), muscle score of shoulder (MSS), muscle score of back (MSB), muscle score of thigh (MST), roundness score of thigh (RST), loin thickness score (LTS), and overall muscle development percentage (OMP) of Charolais weaned calves in Hungary. Multi-trait analysis of variance (GLM) and weighted linear regression analysis were used to process the data. Calves carrying the allele in the heterozygous form achieved approximately 0.14 points higher MSB, MST and LTS, and 1.2% higher OMP, and gained 8.56 kg more CWW than their counterparts not carrying the allele ( < 0.05). As for the allele, there was a difference of 4.08 kg in CWW of the heterozygous animals, but this difference could not be proved statistically. The other alleles had no significant effect on the evaluated traits.
在对活牛进行视觉体型评分时，以及通过检查不同的分子遗传信息（例如可能负责肌肉发育的基因），都可以评估活牛的屠宰价值。在本研究中，对匈牙利夏洛来断奶犊牛的出生体重（BIW）、产犊难易度（CAE）、205日龄断奶体重（CWW）、肩部肌肉评分（MSS）、背部肌肉评分（MSB）、大腿肌肉评分（MST）、大腿圆润度评分（RST）、腰部厚度评分（LTS）和整体肌肉发育百分比（OMP），检测了该基因（）的、、、和等位基因。采用多性状方差分析（GLM）和加权线性回归分析对数据进行处理。携带杂合形式等位基因的犊牛，其MSB、MST和LTS比不携带该等位基因的犊牛高出约0.14分，OMP高出1.2%，CWW比不携带该等位基因的犊牛多增加8.56千克（<0.05）。至于等位基因，杂合动物的CWW差异为4.08千克，但这一差异无法得到统计学证明。其他等位基因对所评估的性状没有显著影响。
