Recently, a mutation has been discovered in the rhyanodin-receptor gen
e causing malignant hyperthermic syndrome (MHS) in pigs. Taking advant
age of the RCR analysis of tissue samples from pigs of the Deutch Land
eras breed we could have demonstrated that the gene-diagnostics MHS an
alysis is a simple, reliable and significant way of gene-typing for th
e stress resistance. Employing this test with sufficient reliability a
nd effectivity will make it possible to create homozygous stress resis
tant lines and to produce heterozygous stress resistant animals having
both good meat quality tending to improvement and good feeding charac
ters. The advantages of this first gene-technological technique just r
eady for application in animal breeding seem to ensure its quick imple
mentation into the applied pig breeding.
