摘要：

The main objectives of this investigation were to monitor the birth weight of calves and gestation length following artificial insemination (Al) and transfer of in vivo or in vitro produced Korean native, Hanwoo embryos. Embryos produced in vivo were recovered from uterine flushings of superovulated cows 7 days after Al. Those embryos produced in vitro were co-cultured with cumulus cells for 7-8 days after in vitro fertilization. The birth weights of calves following the transfer of in vitro produced (IVP) embryos were heavier than calves from both of AI- and in vivo-derived embryo transferred calves in both sexes (29.6, 24.1 and 25.2 kg, respectively, P < 0.05). The IVP calves also had a longer gestation length (293.9, 285.8 and 283.8 days, respectively, P < 0.05). (C) 2001 Elsevier Science B.V. All rights reserved.
