GENETIC TRAITS OF THE BELARUSIAN BLACK-AND-WHITE PIG BREED
Abstract
Methods of molecular genetic analysis are widely used to assess the genetic structure and study the dynamics of population genetic processes in populations of animals, which will allow to preserve and improve the unique traits of the Belarusian Blackand-White breed of pigs. This paper contains materials of microsatellite analysis of the Belarusian Black-and-White breed at KSUP Plemzavod Lenino, SGC Vikhra and OJSC SGC Zarechye, carried out to determine heterozygosity or genetic diversity of the population, the degree of inbreeding of animals in the lines. The Belarusian Black and-White pigs have five loci (SO005, SO386, SO355, SO155 and SW857) out of nine with confirmed significant deviation from the state of genetic equilibrium. The greatest number of “private” alleles was identified among the animals bred in OJSC SGC Zarechye. Boars with determined “private” alleles at microsatellite loci reliably confirm their linear affiliation and are considered to be successors of the same-name lines. This gives reason to consider these alleles as marker alleles for these lines and use them in breed selection and preservation.
