Abstract

The objective of this study was to investigate the effects of dehairing methods and sex on various traits of pork quality, as well as on tissue levels of the boar taint compounds androstenone and skatole. At the early postmortem period, dehided pigs showed higher muscle pH levels (p<0.05), lower temperatures (p<0.05) and lower drip loss (p<0.001) than scalded pigs. Thus, the dehairing method can affect the early postmortem glycolytic rate and water-holding capacity. Moreover, the differences in meat quality traits between the genders were small, and not considered to have practical importance. The scalding method had only a limited effect on the androstenone content. On the other hand, the scalded entire males exhibited a lower content of skatole than the dehided entire males (p<0.01). These results appear to indicate that the heating treatment from the scalding process influenced the reduction of skatole content for the scalded entire males.
