Abstract
Embryos were recovered non-surgically 7 days after estrus from superovulated three donor heifers. Transfers were carried out with a modified insemination instrument for 0.25ml capacity straw through the cervix. One morula or early blastocyst was transferred to each of ten recipient heifers. Four recipients were diagnosed as pregnant by rectal palpation at 33 and 53 days after the embryo transfer.
