ASSOCIATION OF MAJOR HISTOCOMPATIBILITY COMPLEX ANTIGENS (BOLA-A) WITH AI BULL PROGENY TEST-RESULTS FOR MASTITIS, KETOSIS AND FERTILITY IN NORWEGIAN CATTLE
Cm. Mejdell et al., ASSOCIATION OF MAJOR HISTOCOMPATIBILITY COMPLEX ANTIGENS (BOLA-A) WITH AI BULL PROGENY TEST-RESULTS FOR MASTITIS, KETOSIS AND FERTILITY IN NORWEGIAN CATTLE, Animal genetics, 25(2), 1994, pp. 99-104
Altogether 424 Norwegian AI bulls, progeny tested for clinical mastiti
s, ketosis and fertility (recorded as nonreturn percentage), were type
d by Edinburgh and Oslo allo-antisera to bovine lymphocyte antigens (B
oLA-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 keto
sis. The previously reported associations of A11 and w16 with relative
susceptibility to mastitis were not confirmed in the present material
.
