The aim of this study was to provide a comprehensive literature review and evaluation of research on the influence of androstenone and skatole for boar live weight, which thanks to modern trends sensitive issue.
Skatole is malodorous indole compound, which is formed in the colon of pigs later leads to deposition in adipose tissue, causing the so-called. Boar odor.
Steroid androstenone is produced by Leydig cells of the testes boars, when a part is floated urine, partly accumulate in saliva, to stimulate the sows and part is accumulated in the adipose tissue.
The chromatographic method suitable for detecting substances responsible for boar odor was developed on a gas chromatograph mass spectrometer using chemical standards.
According to the results, we can evaluate that the differences between imunocastraties and boars are minimal, not only in fattening values, but also at the height of the back fat or muscle growth musculus longissimus lumborum et thoracis. Only with differing indicators are the amount of androstenone and skatole, which confirms that feeding into higher slaughter weight pigs is unprofitable, because the amount of these substances is many times higher than allowed by European standard. The meat of boars is therefore inconvenient and are a much better choice imunokastráti.
The hypothesis that a live weight of influence on behalf of androstenone and skatole in fat tissue boars are so confirmed.
