The Survival of Single Blastomeres of Pig Eggs Transferred to Recipient Gilts

Abstract

Single blastomeres of four-and six-celled pig eggs, either enclosed in their own zona pellucida, or injected into a foreign zona pellucida, were transferred to recipient gilts which were autopsied 5-6 days later. A control group in which the zona pellucida was penetrated without disturbing the blastomeres was included in the experiment. At autopsy the following percentages of transferred eggs were recovered as
