Publication Type: Proceedings Publication Acceptance Date: 10/12/2001 Publication Date: N/A Citation: N/A Interpretive Summary: The development of embryo freezing technologies revolutionized cattle breeding. Since then, advancements in cryobiology, cell biology and domestic animal embryology have enabled the development of embryo preservation methodologies for our other domestic animal species, including sheep and goats. Recently, technologies have been developed to cryopreserve epig embryos, notorious for their extreme sensitivity to cooling, while horse embryo cryopreservation is in its infancy. This manuscript reviews development and state-of-the-art of embryo preservation technology in our domestic farm animal species. In the near future, use of preserved embryos will be a routine breeding alternative for all domestic animal species, providing: preservation methodology for maternal germplasm; global genetic transport; increased selection pressure of herd genetics; breeding line regeneration or proliferation; and methodology for genetic resource rescue. .
