摘要: Abstract In Jordan, the Arabian Oryx (Oryx leucoryx) is considered among most important wild ungulates. The listed as vulnerable species according to International Union for Conservation of Nature (IUCN). Based on author’s knowledge, estrus synchronization in has never been investigated.

Prior CIDR application, animals were subjected transabdominal ultrasonic examination twice, two weeks apart exclude pregnancies. A single was inserted (Day 0) period days. At removal 7), administered injection prostaglandin F2α (PF2α) and equine chorionic gonadotropin (eCG). Blood samples collected from all before, during after progesterone (P4) analysis.
