IMPLEMENTATION OF GENOMIC INFORMATION IN SELECTION OF BOARS ON SKATOLE AND ANDROSTENONE CONCENTRATIONS [PDF]

Poljoprivreda, 2015
Genomic predictors offer an opportunity to overcome the limitations of classical selection against boar taint, and this study evaluated different approaches to obtain such predictors. Samples from 941 pigs were included in a design which was dominated by

Enzymatic Basis for the Oxidative Branch of Aromatic Amino Acid Fermentation Leading to p-cresol Formation. [PDF]

Adv Sci (Weinh)
In anaerobic bacteria, tyrosine serves as an electron donor in the oxidative Stickland fermentation branch, generating p‐hydroxyphenylacetate, ATP and reduced ferredoxin for decarboxylation into p‐cresol. ABSTRACT The phenolic metabolite p‐cresol is a byproduct of tyrosine fermentation by certain strictly anaerobic bacteria, including the human gut ...

Mechanistic Studies of a Skatole-Forming Glycyl Radical Enzyme Suggest Reaction Initiation via Hydrogen Atom Transfer

Journal of the American Chemical Society, 2022
Gut microbial decarboxylation of amino acid-derived arylacetates is a chemically challenging enzymatic transformation which generates small molecules that impact host physiology.

Can sensory boar taint levels be explained by fatty acid composition and emitted volatile organic compounds in addition to androstenone and skatole content?

Meat Science, 2022
This study aimed at understanding which molecules were responsible for the differences existing in boar taint sensory evaluation. The latter was therefore linked to the results of skatole and androstenone chemical analyses, fatty acid composition and VOC

Copper(II/III) Redox Couple Enables C─H Methylation via a Radical Mechanism Analogous to SAM Enzymes

Angewandte Chemie, EarlyView.
Biological C–H methylation proceeds through radical pathways mediated by one‐electron redox cofactors, yet no synthetic model has reproduced this reactivity. Here, we report the first isolable Cu(II/III)–methyl complexes that mediate C–H methylation through hydrogen atom transfer and methyl radical rebound.

Single amino acid residue mediates reciprocal specificity in two mosquito odorant receptors

eLife, 2022
The southern house mosquito, Culex quinquefasciatus, utilizes two odorant receptors, CquiOR10 and CquiOR2, narrowly tuned to oviposition attractants and well conserved among mosquito species.

A genome-wide association study on androstenone levels in pigs reveals a cluster of candidate genes on chromosome 6 [PDF]

, 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-

Can Hydrolysable Tannins in Diet of Entire Male Pigs Affect Carcass, Pork Quality Traits, Amino and Fatty Acid Profiles, and Boar Taint, Skatole and Androstenone Levels?

Animals, 2021
Simple Summary The increasing societal concern in animal welfare has changed centuries-old practices in pig breeding. One of the most debatable is the surgical castration of piglets commonly used in many European countries primarily performed to avoid ...

Investigation of the efficacy of immunocastration aimed at the prevention of sex odour in boar meat [PDF]

Acta Veterinaria, 2012
Disadvantage of meat known as boar taint is caused by steroids, androstenone being of particular importance, as well as indole and its derivatives, among which the best known is skatole. The common practice in Europe, in order to control these changes
