Transfer of bisected cattle embryos within the same zona pellucida

Reproduction in Domestic Animals 26(2): 91-93

Transfer of bisected cattle embryos within the same zona pellucida

Cattle embryos at the compact morula and blastocyst stages were bisected by two different methods. In some embryos the embryo bisection was performed outside of the zona pellucida and both halves were replaced into it. Other embryos were bisected within the zona pellucida and no pipetting of the halves was required. They were transferred to synchronized recipient cows and the pregnancy rates and twinning rates were evaluated.
