ABSTRACT
Most of the inguinal and scrotal hernias (hernia inguinalis and scrotalis) are birth defects in humans, under the control of genetic and environmental factors. However, the molecular mechanism of etiology remains elusive [1-5]. In the pig breeding industry, infrequent incidence of inguinal and scrotal hernias can happen for certain pig breeds and lines and genetic factors are believed to drive the hernia development [6-8]. Without clinical examination, these two defects cannot be easily distinguished, and most of the time, this is the case.
