Abstract
Micromanipulation of bovine embryos to produce monozygotic twins is now being offered by some of the more progressive commercial cattle embryo transplant units around the world. One of the primary advantages of embryo splitting is the capability of increasing the number of progeny from genetically superior females. Pregnancy rates can be obtained in cattle from fresh “half embryos (demi-embryos) which are comparable to those of intact embryos (Voelkel et al. 1984; Takeda et al. 1986). When sufficient surrogate females are available, good quality embryos can be bisected and transferred, thus potentially doubling the number of offspring from embryos harvested from valuable donor animals.
