Study on simplification of monozygotic twins production by transfer of bovine embryos Production of calves by direct transfer of frozen-thawed embryos after separated into two parts

牛の一卵性双子生産の簡易化試験 分割凍結卵の直接移植法による双子生産試験

Research overview:
The technique that bovine embryos separated into two parts artificially are preserved after frozen using ethylene glycol as cryoprotectant under denuded condition, then transfer to recipient directly after thawing is established for monozygotic twins production. It will promote to efficient utillization of bovine embryos and rising calf production rate. 1) Viability of bovine embryos by different densities of cryoprotectant and thier twining. 2) Possibility of direct transfer with making plural corpus luteum and their twining. 3) Prevention of abortion and stillbirth.
