Overview
Arabian Oryx appears on the Exotic Wildlife Association species list as Oryx (Arabian), Oryx (White) — ESA: Endangered; CITES: Appendix I. [1]
Native range
Oryx leucoryx were originally found in Syria, Iraq, Israel, Jordan, Sinai, and the Arabian Peninsula. [2]
Size
100–210 kg (ADW range). [2]
Lifespan
20.8 years (captivity, average). [2]
Breeding & gestation
Gestation average 8 months; offspring per birth: 1. [2]
Temperament & social structure
Not verified from a primary source for this page.
Habitat needs
Usually O. leucoryx are found in arid plains and deserts, however they have also been found to inhabit rocky hillsides and thick brush. ADW biomes: desert or dune, savanna or grassland, chaparral. [2]
Where they thrive (Texas / US)
Not verified from a primary source for this page.
Space per animal
No verified species-specific stocking rate was found. Carrying capacity depends on rainfall, range condition and competing grazers—get a range/stocking assessment (NRCS or Texas A&M AgriLife).
Housing & shelter
Not verified from a primary source for this page.
Fencing
Texas Parks & Wildlife states game fences at least 8 ft high (woven-wire or high-tensile) are the only fully reliable deer-exclusion fence. That is the common high-fence standard for deer and antelope; a species-specific minimum for this animal was not found in a primary source. [3]
Natural diet
O. leucoryx feed on diverse types of grasses and shrubs found in their arid habitat. They go to streams and water holes to drink. [2]
Feed & supplementation
No verified species-specific protein % or mineral formula was found. Texas deer guidance (16–20% CP pellet; 13–16% CP for growth/reproduction) is sometimes used as a reference point but is not antelope-specific—work with a ruminant nutritionist/exotic vet. [4][5]
Common health issues & parasites
Haemonchus contortus and Longistrongylus dominate abomasal worm burdens in free-ranging exotic antelope in Texas (sable, addax, blesbok studied); captive wild ruminants show anthelmintic resistance, so use fecal egg counts and fecal egg-count reduction tests instead of routine blanket deworming. [6][7]
Vet care & vaccination
No vaccines are labeled for this species in the US; any vaccination protocol is extra-label and should be set by a veterinarian experienced with exotic hoofstock. (No specific protocol was verified for this page.)
Handling & capture
Capture myopathy—muscle damage from pursuit, restraint and transport—is often fatal in wild ungulates. Minimize chase time and stress, avoid hot conditions, use appropriate chemical immobilization by a vet, and release/unload quickly. [8]
Conservation status
IUCN Red List: Vulnerable. [9]
Legal notes (general info, not legal advice)
Listed Endangered under the US Endangered Species Act (per the EWA list; confirm current status on USFWS ECOS). Interstate sale or transport of ESA-listed animals requires federal authorization. CITES: Appendix I. General information, not legal advice. USDA APHIS licensing under the Animal Welfare Act applies to dealers and exhibitors; check USDA and your state wildlife and animal-health agencies before buying, moving or selling. [1][10][11]
