Abstract: Morulae and blastocysts obtained from ewes 5, 7 and 9 days after oestrus were transferred to 120 recipients whose oestrous cycles were either synchronized or \m=+-\2 or 3 days out ofphase relative to the onset of oestrus in the donors. When synchronization was exact 75% of all recipients became pregnant. A high proportion of pregnancies were, in general, also obtained where the onset ofoestrus in the recipient differed from that of the donor by \m=+-\2days. With a difference of \m=+-\3 days, however, only 8 % of ewes became pregnant. The survival of 5-day morulae transferred to 7-day recipients was lower than when 9-day blastocysts were transferred to 11-day recipients. The results are discussed with reference to possible factors associated with early embryonic mortality. |
