Use of DNA-markers at perfection of lines and families of pigs of the Belarus blackmotley breed

Abstract

On the basis of the spent molecular-genetic testing on genes RYR 1, H-FABP and ESR and estimations of own efficiency of male pigs and the sows planted in КСПУП «SGC «Zare- che», the plan of selection of parental pairs for reception of the highly productive repair young growth is made, allowing effectively to improve families, using thus potential of male pigs.For self-repair the young growth received from parents of following genotypes is selected: NN on gene RYR 1, dd, Dd and HH on gene H-FABP, BB and AB on gene ESR.Regular carrying out of DNA-testing of parental forms allows to exclude undesirable genotypes and accelerates purposeful selection work with separate lines and families on perfec-tion of meat and reproductive signs of breed.
