DNA analysis of the examined sheep showed the presence of 200 alleles in locus DRB1, established on the basis of the length of a fragment of this gene amplified using PCR. The analysis of variance conducted for the FEC trait in genotyping groups showed a statistically significant association between the genotype in locus DRB1 and number of nematode eggs in sheep faeces. The presence of a given DRB1 allele in the genotype of animals examined had significant effect on parasite resistance. Moreover, the significant association between FEC value in allelic groups of paternal half-sibs and the segregation of paternal alleles was also significant
