The effect of transferrin genotypes and genes and globulin antigens on sheep resistance/susceptibility to mastitis was analysed. The udder health condition was diagnosed on the basis of the somatic cell count in 1 ml of milk and results of bacteriological tests. It was found that sheep with the transferrin genotype AC, AD and CC were characterised by a better health of the mammary gland than the remaining ewes. Among 9 transferrin alleles observed in the examined sheep, only the presence of transferrin I allele in the ewes genotype was connected with the somatic cell count below the mean value of this trait. The presence of transferrin A allele in the sheep's genotype was connected with a small infection of milk with mastitis pathogens. The serum globulin antigens analysed did not significantly affect the somatic cell count in the milk of the examined ewes. However, the antigens A2, NS1 (antigens of ß-globulin) and GB2 (antigen of class IgG immunoglobulins) as well as the globulin antigen A6 and GA1 antigen of class IgG immunoglobulins showed to have a significant effect on the level of sheep milk infection.
