Characterisation of androstenone metabolism in pig liver microsomes

Chemico-Biological Interactions, 2004
Androstenone (5 alpha-androst-16-en-3-one) is a steroid pheromone produced in the testis. Excessive accumulation of androstenone together with skatole (3-methyl-indole) in the adipose tissue of some male pigs leads to "boar taint". In isolated pig hepatocytes androstenone represses the expression of cytochrome P450IIE1 (CYP2E1), the enzyme principally ...

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.

Testicular development, androstenone levels and androstenone odour of untreated and trenbolone implanted boars

Journal of the Science of Food and Agriculture, 1991
AbstractTwelve boars were implanted at 50 kg live weight with 300 mg of trenbolone acetate (TBA), and 12 male litter mates were held as controls. All animals were slaughtered at 175 days of age and ∼ 100 kg live weight. TBA administration led to a decrease in testicle size (P<0.001) and testosterone levels (P<0.05).

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 ...

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

Androstenone and testosterone levels and testicular morphology of Duroc boars related to estimated breeding value for androstenone

Theriogenology, 2013
Androstenone and testosterone levels in Duroc boars with an estimated breeding value for androstenone (EBV(androstenone)) were followed in the period from birth to sexual maturity. The breeding value for androstenone had been estimated based on androstenone levels in 1202 Duroc boars at an age of 24 weeks. Testosterone and androstenone levels in plasma

Norwegian consumers' acceptability of boar tainted meat with different levels of androstenone or skatole as related to their androstenone sensitivity

Meat Science, 2010
The aim of work was to study Norwegian consumers' acceptance of pork meat with different levels of skatole and androstenone. One group of androstenone sensitive consumers (N=46) and one group of non sensitive consumers (N=55) participated in a home test and evaluated 11 samples with different skatole (range 0-0.35 ppm) and androstenone (range 0-9.0 ppm)

The characterization of androstenone transport in boar plasma

The Journal of Steroid Biochemistry and Molecular Biology, 2019
The transport of steroids by plasma proteins influences the amount of steroid available for uptake by the target tissue. In the boar, androstenone is transported to the adipose tissue where it accumulates to cause an off-odour or off-flavour in pork, known as boar taint.

Acceptability of entire male pork with various levels of androstenone and skatole by consumers according to their sensitivity to androstenone

Meat Science, 2012
Consumer acceptability of entire male pork at eating was assessed in three experiments. The 140 consumers involved in each experiment were classified as insensitive (INSENS) to the odor of pure androstenone or sensitive perceiving it as pleasant (SENS-PLEA) or unpleasant (SENS-UNPL). Entire male pork with very low skatole and androstenone levels (LS-LA)

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.
