Thoracic depth/width ratios (TDWRs) were calculated from measurements of the parents (i.e., common dam and two sires) and puppies in two litters of Irish setters. The TDWRs of the parents, distribution of TDWRs in the litters, and comparisons with earlier population studies suggest that an incompletely dominant major gene and a background of minor genes and environmental factors are responsible for the TDWR. A history of gastric dilatation-volvulus (GDV) (i.e., bloat) was correlated with high TDWRs in this family as it was for Irish setters and certain other breeds studied earlier. It may be possible to reduce the incidence of GDV by selective breeding of dogs with lower TDWRs.
胸廓深度/宽度比(TDWRs)是根据两窝爱尔兰雪达犬的亲代(即共同的母犬和两只公犬)及幼犬的测量数据计算得出的。亲代的TDWRs、窝内TDWRs的分布以及与早期群体研究的比较表明,一个不完全显性的主基因以及次要基因和环境因素的背景共同决定了TDWR。在这个家族中,胃扩张-扭转(GDV,即腹胀)病史与高TDWRs相关,就像早期对爱尔兰雪达犬和其他某些品种的研究一样。通过选择性繁殖TDWR较低的犬只,有可能降低GDV的发病率。
