Overview
Large oryx with straight ringed horns 60–150 cm long; introduced into Mexico and the southwestern US. [1]
Native range
Southern Africa; wooded grassland at ~900–1,200 m elevation and arid areas. [1]
Size
Females 180–225 kg, males 180–240 kg; shoulder height 115–125 cm; body length 180–195 cm. [1]
Lifespan
~18 years wild; 20–22 years captive. [1]
Breeding & gestation
~8.5 months (270 days); calves 9–15 kg at birth; females mature at ~2 years. [1]
Temperament & social structure
Herding antelope; horns are used defensively. [1]
Habitat needs
Arid adapted: forage plus wild melons/cucumbers can supply all water needed (~3 L per 100 kg body weight daily). [1]
Where they thrive (Texas / US)
INFERRED only: desert-adapted (see Habitat needs), so the arid Trans-Pecos/Chihuahuan Desert is the closest climate match; no Texas county distribution data found. See the interactive Texas species map (../site/map.html). [1]
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
No verified cold threshold; provide shelter from cold rain as a precaution.
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. [2]
Natural diet
Grasses and browse plus water-rich melons and tubers. [1]
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. [3][4]
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. [5][6]
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. [7]
Conservation status
IUCN Red List: Least Concern. [8]
Legal notes (general info, not legal advice)
