RNA deep sequencing reveals novel candidate genes and polymorphisms in boar testis and liver tissues with divergent androstenone levels. [PDF]
PLoS ONE, 2013 Boar taint is an unpleasant smell and taste of pork meat derived from some entire male pigs. The main causes of boar taint are the two compounds androstenone (5α-androst-16-en-3-one) and skatole (3-methylindole).

Ability to smell androstenone is genetically determined. [PDF]
Proceedings of the National Academy of Sciences, 1984 Some adult humans cannot detect the odor of androstenone (5 alpha-androst-16-en-3-one), a volatile steroid. To test for the presence of genetic variance associated with this trait, adult twins were tested for their ability to smell androstenone and another odorant, pyridine, that is readily perceived by most adults. Ascending concentration, two-sample (

Animal, 2008 The present study investigated the presence of a single-nucleotide polymorphism (G > T) at base −8 upstream of ATG in 5′ untranslated region of cytochrome b5 (CYB5A) gene in Swedish pig populations and evaluated the significance of this polymorphism for ...

Regulation of cytochrome P450 mRNA expression in primary porcine hepatocytes by selected secondary plant metabolites from chicory (Cichorium intybus L.) [PDF]
, 2013 Chicory (Cichorium intybus) has been shown to induce enzymes of pharmacokinetic relevance (cytochrome P450; CYP). The aim of this study was to investigate the effects of selected secondary plant metabolites with a global extract of chicory root, on the ...

BMC Genetics, 2010 Background In many countries, male piglets are castrated shortly after birth because a proportion of un-castrated male pigs produce meat with an unpleasant flavour and odour. Main compounds of boar taint are androstenone and skatole. The aim of this high-

Development of reference methods for the detection and the measurement of the main compounds responsible for boar taint [PDF]
, 2014 Meat from male pigs may develop an off-flavour, commonly known as boar taint. For that reason male piglets are surgically castrated at young age to avoid the potential off-flavour formation.

Animal, 2015 To investigate the extent to which the level of androstenone and skatole decreases with a decrease in live weight and/or age at slaughter of entire male pigs produced under organic standards, 1174 entire male pigs were raised in parallel in five organic ...

Differential expression and co-expression gene networks reveal candidate biomarkers of boar taint in non-castrated pigs [PDF]
, 2017 Boar taint (BT) is an offensive odour or taste observed in pork from a proportion of non-castrated male pigs. Surgical castration is effective in avoiding BT, but animal welfare issues have created an incentive for alternatives such as genomic selection.

New way of definition of an androstenon
Proceedings of the Voronezh State University of Engineering Technologies, 2019 By means of "an electronic nose" the problem of detection in salted pork fat of an androstenon is solved, even small concentration of which negatively affect consumer appeal of a product. The massif from eight differently selective gas sensors is applied to detecting of an androstenon.
