Analysis of genetic and nutritional determinants to reduce the boar taint substances skatole and androstenone in porcine meat
Project
Project code: AZ II-1-F 41-2010.02
Contract period: 01.05.2010
- 30.04.2012
Budget: 77,878 Euro
Purpose of research: Applied research
Androstenone and skatole are causing an odour and flavour in porcine meat, that
is recognized by consumers as unpleasant. This phenomenon has been
designated as boar taint. The goal of the proposal is to identify genetic and
environmental determinants affecting the androstenone and skatole
concentration of the meat from uncastrated male pigs. This is a prerequisite to
reduce the smell and taste problem of this meat by breeding efforts. Meat
samples and samples taken from intestine as well as tissue samples from
intestine will be provided by the BMBF funded project “EN-Z-EMA”. These
samples will be used to analyse the microbial population based on DNA-profiles
within the intestine and to characterize the metabolic status by analyzing gene
expression within the tissue. It is expected, that nutritional as well as genetic
causes for a high androstenone and skatole concentration in meat will be
revealed. Consequently, this will contribute to solve the problem.
