Embryo transfer techniques are similar to those used in the horse. Embryo recovery was low when collection was attempted six to seven days after ovulation (Vendramini et al, 1997). The pregnancy rate following nonsurgical transfer is generally low at 20% and has been attributed to the release of PG F2α and luteolysis following manipulation of the cervix (Panzani et al, 2006).
