Abstract

The effect of the porcine myogenin (Myog) 3' polymorphism on birth weight, growth rate, carcass weight, lean weight, lean meat percentage and back-fat thickness has been investigated in Hungarian Large White pigs. MYOG genotypes were determined by PCR-RFLP assay. The obtained MYOGA frequency value was 0.6275. Due to the small number of BB piglets the effect of the MYOG genotypes on birth weight was not significant; however, an increasing tendency was observed from genotype AA to BB. The growth rate difference between MYOG genotypes was significant: BB animals showed the highest growth rate values during the fattening period. Since few results are available on the possible use of MYOG gene polymorphism in selection to improve carcass and growth traits, by this study the authors hope to provide additional data on this particular subject.

摘要

在匈牙利大白猪中研究了猪肌细胞生成素（Myog）3'多态性对出生体重、生长速率、胴体重量、瘦肉重量、瘦肉率和背膘厚度的影响。通过PCR-RFLP分析确定MYOG基因型。所获得的MYOGA频率值为0.6275。由于BB仔猪数量较少，MYOG基因型对出生体重的影响不显著；然而，从基因型AA到BB观察到一种增加趋势。MYOG基因型之间的生长速率差异显著：BB动物在育肥期表现出最高的生长速率值。由于关于MYOG基因多态性在选择中用于改善胴体和生长性状的可能用途的可用结果很少，作者希望通过本研究提供关于这一特定主题的更多数据。
