The results of bull-sire examination on the presence of BLAD genes and CVM-mutation in the public joint stock company "Krasnoyarskagrogosplem" are presented in the article. The research has confirmed that the lack of thorough and comprehensive genetic examination in the bull-sire use may lead to the spread of serious genetic defects and abnormalities that cause enormous economic damage to AIC entrepreneurs.
