Associations of bovine lymphocyte antigens with milk and meat production traits of Norwegian cattle.
Bovine lymphocyte antigens of class I were defined for 434 AI bulls of Norwegian Cattle, which is a dual purpose breed. The antigens w16, A2, and A8 occurred at highest frequencies. A gene substitution model was used to compare bovine lymphocyte antigens with total breeding value and breeding values for milk yield, milk fat percentage, milk protein percentage, and meat production. Several bovine lymphocyte antigens were significantly associated with the traits in question: low fat percentage was associated with A8, A10(w50), and A11; high milk protein percentage with A13; and low meat production with the rare antigen w1. Associations of the bovine lymphocyte antigens and milk yield were not significant.
