Резюме: Danube white boars were genotyped for ESR and FUT1 loci. Detection of ESR and FUT1 genotypes was performed by PCR-RFLP method. Sperm quality traits were studied of genotyped board - semen volume, motility, sperm concentration, dead and abnormal percentage spermatozoa, total number and number of alive spermatozoa. The total number and number alive spermatozoa were significantly higher in boars with ESR DD genotypes compared to other ESR genotypes. Boars with AA genotypes of FUT1 gene that could be with resistance to Escherichia coli F18 infections were with lower sperm quality traits. This could be one of the reasons for low frequency of allele A in pig populations.
