Bovine blastocysts were obtained by totally in-vitro technique and then transferred to recipient cows. Total of 15 calves (including 4 premature calves) were obtained from 11 recipients. Four calves were obtained from the transfers of fresh blastocysts and 9 calves were obtained from the transfers of frozen-thawed blastocysts. Two calves were obtained from the bisected fresh blastocyst. The males and 5 females were delivered. Birth weight of calves was within normal range except one female, and all calves appeared to be completely normal.
