[Pregnancy in New World camelids]

There is a growing number of llama- and alpacabreeders in Europe. Therefore veterinarians are often asked to intervene in clinical management of different problems, especially reproductive problems. In this review the authors attempt to summarize the different possibilities of pregnancy diagnosis and to give an short overview of reproduction in female llamas and alpacas. South American Camelids are induced ovulators and ovulation will occur within 12 to 24 hours following a single breeding. Llamas and alpacas develop follicular waves. The females will usually not ovulate unless a 7 mm or larger follicle exist on one of the ovaries. Corpus luteum is needed for maintenance of pregnancy.
