Summary Altogether 424 Norwegian AI bulls, progeny tested for clinical mastitis, ketosis and fertility (recorded as nonreturn percentage), were typed by Edinburgh and Oslo allo‐antisera to bovine lymphocyte antigens (BOLA‐A) over a 7‐year period. Significant effects of BOLA‐A on disease were revealed. A2 was associated with relative resistance to mastitis, a positive influence on fertility, and a possible relative resistance to ketosis, while A13 was associated with relative resistance to ketosis. The previously reported associations of All and w16 with relative susceptibility to mastitis were not confirmed in the present material.
