The objectives of the present experiment were to compare survival after transfer of bovine embryos produced in vivo with those produced in vitro and to examine the physical characteristics of fetuses produced from these transfers. Embryos produced in vivo (Holstein x Angus) were recovered from uterine flushings of superovulated heifers 7 days after first artificial insemination, and embryos produced in vitro (Holstein x beef breeds) were collected 7 days after insemination. Embryos were paired by source (in vivo, in vitro), stage (compact morula, blastocyst), and quality grade (excellent = 1, good = 2), and transferred nonsurgically to recipient heifers on Day 7 (+/- 1 day) of the estrous cycle. Pregnancy status was monitored by determination of serum progesterone concentrations, ultrasonography, and palpation through 7 mo of gestation, at which time fetuses were recovered. In comparison with grade 1 embryos produced in vivo, the risk of embryonic death after transfer was similar for grade 2 embryos produced in vivo (p = 0.56) and for grade 1 embryos produced in vitro (p = 0.88). By contrast, grade 2 embryos produced in vitro were at greater (p = 0.04) risk of embryonic death. Embryo loss was associated (p = 0.01) with increased serum concentrations of progesterone in recipients at the time of transfer. At 7 mo of gestation, fetuses from embryos produced in vitro were heavier (p = 0.02) than fetuses from embryos produced in vivo and had skeletal measurements that were disproportionate (p < or = 0.04) to body weight.
