Successful transport of frozen cattle embryos from New Zealand to Australia

Abstract

Several laboratories have reported the birth of young from frozen–thawed mouse embryos transferred to recipient females (Whittingham, Leibo & Mazur, 1972; Wilmut, 1972) and frozen mouse embryos have been successfully transported from North America to the United Kingdom (Whittingham & Whitten, 1974). Of the domestic species, continued development in vivo and in vitro has been achieved with cattle (Wilmut & Rowson, 1973; Bilton & Moore, 1976a), sheep (Moore & Bilton, 1976; Willadsen, Polge, Rowson, & Moor, 1976) and goat (Bilton & Moore, 1976b) embryos stored in liquid N2, and the potential value of frozen storage for the transport of embryos has been noted.
