A study on association between mastitis and serologically defined class I bovine lymphocyte antigens (BoLA-A) in Norwegian cows.
A total of 102 cows was tested for class I antigens of the bovine major histocompatibility complex. Half of the animals (51) had completed at least four lactations without any veterinary treatment for mastitis. The distribution of BoLA-A antigens among these relative mastitis-resistant cows was compared to that in the other half of the material (51), which comprised animals with at least one recorded treatment for mastitis. There were no statistically significant differences in BoLA-A antigen frequency between cows with mastitis and cows without mastitis. The two most common antigens were A2 and w16. The frequency of these two antigens deviated from earlier estimates within the Norwegian cattle (NRF) population, the difference for w16 being statistically significant.
