Obtaining an Interspecific Hybrid of Cranes by Artificial Insemination with Frozen-thawed Semen
      
Studies of artificial insemination of cranes and cryoconservation of their semen have been carried out in the nursery of rare species at the Oka Biosphere Reserve for many years.
      
As a result, an interspecific hybrid of cranes was obtained, which confirmed the possibility of producing a bank of cryoconserved crane semen.
