Genetic and metabolic aspects of androstenone and skatole deposition in pig adipose tissue: A review
نویسندگان
چکیده
It has been drawn to the attention of the authors that in Figure 1 the common intermediate products of the transformation of progesterone and 5,16 androstadien-3bol into androstenone is 4,16-androstadien-3-ene (and not 4,16 androstadien-3-one). In addition, the list of the final products of androstenone sulfonation has been completed. This corrigendum published in issue 5, 2008 is freely available in electronic form on the web site of GSE (http://www.gse-journal.org/).

Biochemical, nutritional and genetic effects on boar taint in entire male pigs.
Pork odour is to a great extent affected by the presence of malodorous compounds, mainly androstenone and skatole. The present review outlines the current state of knowledge about factors involved in the regulation of androstenone and skatole in entire male pigs. Androstenone is a pheromonal steroid synthesised in the testes and metabolised in the liver. Part of androstenone accumulates in adip...
متن کاملNutritional Influences on Skatole Formation and Skatole Metabolism in the Pig
Skatole is a tryptophan (TRP) metabolite with fecal odor. Together with the testicular steroid androstenone it is regarded as a main determinant of boar taint, even if elevated concentrations of skatole occur occasionally in gilts and barrows. Skatole concentrations in adipose tissue result from a complex process, which includes the availability of TRP and the presence of specialized bacteria i...
متن کاملRegulation of CYP2A6 protein expression by skatole, indole, and testicular steroids in primary cultured pig hepatocytes.
CYP2A6 is one of the enzymes involved in the hepatic metabolism of a naturally produced compound, skatole, in the pig. Low CYP2A6 activity has been linked to excessive accumulation of skatole in pig adipose tissue and development of the phenomenon "boar taint." CYP2A6 activity varies between male and female animals, suggesting the involvement of sex hormones in regulation of the enzyme activity...
متن کاملEffect of faecal soiling on skatole and androstenone occurrence in organic entire male pigs.
Production of entire male pigs could be a future strategy for organic pig production. However, production of entire males leads to increased risk of carcasses with elevated boar taint levels. It is hypothesized that skatole levels in pig meat are affected by faecal soiling and that organic housing facilities can increase the risk of pigs being heavily soiled. Therefore, the overall aim of this ...
متن کاملRaising intact male pigs for meat: Detecting and preventing boar taint
Although there are several advantages to raising intact male pigs instead of castrates, boar taint — an unpleasant odor that emanates from boar fat when it is heated — is a potential problem with rearing boars for pork. Two groups of compounds are considered primarily responsible for boar taint: 16-androstenes (mainly 5α-androstenone) and skatole. The 16-androstene steroids are largely secreted...
