Summary

Transfers were made to recipient ewes of sheep eggs stored in serum at 37° C. for up to 5 hr. (fresh eggs), in serum at room temperature for 24 to 48 hr. (stored eggs), or in Whitten's modified Krebs-Ringer-bicarbonate medium for 24 to 48 hr. (cultured eggs). The success of transfer was judged from the presence of embryos at autopsy 25–30 days after transfer.

Fifteen of 42 fresh eggs, 11 of 23 stored eggs and 3 of 15 cultured eggs were found to have developed after transfer.

The findings are discussed.
