Biochemical, nutritional and genetic effects on boar taint in entire male pigs

Animal, 2009
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 ...

Correlations between PORCUS classification and androstenone in boars, and effects of cooking methods thereon [PDF]

, 2020
The aim of this research was to evaluate relationships between the PORCUS classification system and factors affecting boar taint in pork. Intact male pork carcasses (n = 176) were randomly selected in a South African commercial abattoir from three PORCUS

Patterns of plasma sexual steroids in Duroc and Pietrain crossbred male pigs in organic farming and prediction of boar taint risk according to slaughter weight

Animal
Boar taint risk in pork highly depends on fat tissue concentrations of androstenone and skatole, and indole to a lower extent. During pubertal development, androstenone is increasingly produced by testes and accumulates in fat tissues. Skatole and indole

Efficacy of non-nutritive sorbent materials as intestinal-binding agents for the control of boar taint

Animal, 2011
In many countries, male pigs are castrated to prevent boar taint, but this practice raises concerns about animal welfare and reduces the production efficiency of pork. The objective of this study was to develop dietary manipulations to prevent boar taint.

The pig CYP2E1 promoter is activated by COUP-TF1 and HNF-1 and is inhibited by androstenone

, 2004
Functional analysis of the pig cytochrome P4502E1 (CYP2E1) promoter identified two major activating elements. One corresponded to the hepatic nuclear factor 1 (HNF-1) consensus binding sequence at nucleotides -128/-98 and the other was located in the ...

Relationship between carcass weight, adipose tissue androstenone level and expression of the hepatic 3β-hydroxysteroid dehydrogenase in entire commercial pigs

Animal, 2007
Boar taint is a major meat-quality defect in pigs and is due to excessive accumulation of skatole and androstenone in adipose tissue. The present work investigated the relationship between carcass weight, levels of skatole and androstenone in adipose ...

Changes of Androstenone Concentrations in Saliva of Boars with Age

, 2022
With the increasing age of boars, the possibility of androstenone (5α-androst-16-en-3-one (AND), 5α-androst-16-en-3α-ol (α-AND), and 5α-androst-16-en-3β-ol (β-AND)) occurrence increases as well.

Metabolism of androstenone, 17β-estradiol and dihydrotestosterone in primary cultured pig hepatocytes and the role of 3β-hydroxysteroid dehydrogenase in this process.

PLoS ONE, 2015
Steroids metabolism plays an important role in mammals and contributes to quality of pig meat. The main objective of this study was to identify metabolites of androstenone, 17β-estradiol and dihydrotestosterone using primary cultured pig hepatocytes as a

Modulation of porcine cytochrome P450 enzyme activities by surgical castration and immunocastration

Animal, 2009
The present study aimed to evaluate some cytochrome P450 metabolic enzyme activities in hepatic microsomes prepared from entire male pigs (uncastrated pigs), surgically castrated pigs and pigs immunized against gonadotropin-releasing hormone ...
