FIELD: breeding and genetics of agricultural animals, particularly selection in pedigree animal husbandry. SUBSTANCE: method involves artificial insemination of female animals with the semen of a prominent ancestor and, after receiving at least four generations of offsprings, insemination of great-great-granddaughters of the prominent sire with the cryopreserved semen of the same ancestor. Then the cycle is repeated over again, developing the line in the genetic resemblance with the ancestor without close inbreeding. EFFECT: higher efficiency. 1 dwg
