In industrialized countries, the donkey population had a dramatic decrease during the last century and this has brought almost all European donkey breeds to risk. Embryo technologies have already been employed as a tool for the conservation of endangered equid species (e.g. Equus Przewalskii).Today it is possible to obtain pregnancies after the transfer of donkey embryos in synchronized recipients, even though embryo transfer is not widely used as a reproductive technique in this species. So far, very few foals are born after transfer of cryopreserved embryos. To date, no pregnancies have been reported from in vitro fertilization studies. The use of the donkey as a dairy animal, as well as the increased importance of the conservation of endangered donkey breeds, could be the engine for the development and spread of embryo technologies in this species. However, funding from national and international research agencies in this field is still scarce, especially in Europe.
