Reduction of Pig Agonistic Behavior by Androstenone

Journal of Animal Science, 1988
One hundred twenty-four prepuberal crossbred pigs were used in a series of behavioral bioassays to determine the minimum dose of androstenone (5 alpha-androst-16-en-3-one) that would reduce the level of agonistic behavior among dyads of newly regrouped pigs. Randomly selected females and castrated males were used in 21-h videotaped observation periods.

Quantitative determination of androstenone in pig adipose tissue

Journal of Chromatography A, 1986
A simple, cheap and rapid method for the quantitative determination of the boar taint substance, 5 alpha-androst-16-en-3-one, in pig adipose tissue is described. After saponification of the fat the androstenone is extracted, derivatised with o-(pentafluorobenzyl)hydroxylamine hydrochloride in pyridine and analysed by fused-silica open-tubular capillary

Changes in sensitivity to the odor of androstenone during adolescence

Developmental Psychobiology, 1989
AbstractWhile it has been reported that most, if not all, very young children are able to detect the odor of 5α‐androst‐16‐en‐3‐one (androstenone), approximately 40–50% of human adults cannot detect its odor. The present study focused on changes in sensitivity to androstenone was determined in 247 subjects aged 6 to 50. There was a significant increase

Sex Differences in Response to the Odor of Alpha Androstenone

Perceptual and Motor Skills, 1990
Additional analyses of ratings by 98 male and 102 female college students assigned to one of four odor conditions showed no significant correlations for the methyl anthranilate or skatole odor conditions, but the pattern of correlations for men and women was different in the alpha androstenone condition, e.g., if men found alpha androstenone pleasant ...

Immunization against 5α-androstenone in boars

Livestock Production Science, 1985
The effects of specific immunization against 5α-androstenone have been examined in large, genetically homologous groups of boars reared either to bacon weight (90–95 kg live weight) or to heavy manufacturing weight (115–120 kg live weight). At the lighter weight, immunization significantly (P < 0.05) reduced the concentration of androstenone in the ...

Enhanced Sensitivity to Androstenone Following Regular Exposure to Pemenone

Chemical Senses, 1995
The responses elicited by olfactory stimuli may be modified throughout an organism's life. For example, Wysocki et al. found that regular presentations of 5a-androst-16-en-3-one (androstenone) to anosmic subjects resulted in a graded increase in the perceived intensity of this substance in about half of their subjects (Wysocki et al., 1989).

Immunization of pigs against the boar taint steroid androstenone

Journal of Comparative Pathology, 1984
Tissue concentrations of androstenone were measured in untreated control pigs and pigs immunized against 5 alpha-androst-16-en-3-one. Results confirmed that active immunization of male pigs against androstenone is unlikely to prevent the problem of "boar taint" in the carcass meat.

The sulfoconjugation of androstenone and dehydroepiandrosterone by human and porcine sulfotransferase enzymes

Steroids, 2018
Porcine sulfotransferase 2A1 (pSULT2A1) is a key enzyme involved in the testicular and hepatic sulfoconjugation of steroids such as dehydroepiandrosterone (DHEA) and potentially androstenone. This latter steroid is a major cause of boar taint, which is an unpleasant off-odour and off-flavour in pork from male pigs.

Male Sexual Orientation Affects Sensitivity to Androstenone

Chemosensory Perception, 2009
Androstenone has often been discussed as a human social chemosignal, as it is one of the major contributing substances to the human body odor for which humans possess specific receptors. Here, we investigated whether male sexual orientation influences the perception of androstenone.

Human neonatal responses to androstenone

2010
Aims. Human newborns show equal attraction to the odors of amniotic. fluid (AF) and mothers’ colostrum [1]. As 5-a-androst-16-en-3-. one (An) has been found in both fluids [2, 3], we studied it as a. potential vector of this perinatal odor continuity and of neonatal. attraction to the smell of breast and milk [4]. Methods. Two studies. were run.
