[Variability of postvaccinal antibody activity in swine with different blood groups]

In pigs with A--/--, Kace/--, Kace/b; Lbdfi/bdfi-allels in the genotype the titre of postvaccinal antibodies was 4-15 times as high as in pigs with allels Acp; Lbcgi/adhi, Kb/-or K--/--. Frequency of animals with allels, connected with a low titre of antibodies in certain populations ranged from 0 to 11.6%. Such animals grew badly and had a low viability.
