FIELD: biotechnology.
SUBSTANCE: the present innovation deals with individual matching donor sheep to recipient sheep at similar antigenic composition of blood types being correspondent to the value of antigenic similarity index being ra=0.51-1.00, where ra - antigenic similarity index. Moreover, the mentioned antigenic similarity index should be calculated by the following formula: 
where S - the number of similar antigens in a donor sheep and in a recipient sheep, n1 - the number of detected antigens in a donor sheep, n2 - the number of detected antigens in a recipient sheep. The present innovation enables to increase the level of adaptability of transferred ovine embryos by 25%.
EFFECT: higher efficiency of embryo transfer.
