[Frequent occurrence of BoLA w16 in cows susceptible to mastitis].

The association between BoLA class I antigens and mastitis was studied in Boheman Pied breed and its crosses. The mastitis status was followed during two years according to three diagnostic criteria: California Mastitis Test, bacteriological findings and the altered taste of milk. The antigen w16 was found to be significantly associated with susceptibility to mastitis in all diagnostic tests. On the other hand there were some indications that the wll animals were rather resistant to mastitis.
