Optimal conditions for hormonal stimulation of females of ICR, CBAlLac and C57Bl/6j have bean worked out The optimal concentration and spectrum of hormones for each strain was determined. Conditions for in vitro culture of zygotes of different strains were elaborated. It was determined that the important thing for successive in vitro culture of zygotes is the stage of development of fertilized ova, which is characterized by the time of appearance of maternal and paternal pronuclei.
