The camel is the main meat- and milk-producing animal in the desert environment and is characterized by an induced ovulation pattern, in which ovulation occurs in response to copulation. Little is known about the early embryonic development and placentation in camelid species. Here we describe protocols for the culture of both in vitro-produced and in vivo-retrieved camel embryos. A chemically defined medium enables the development of in vitro-produced embryos from cleavage to the hatching blastocyst stage. In vivo-retrieved embryos will survive in vitro for 23 days postinsemination, reaching a diameter of ~5 mm.
