Overview

See native range and biology below. [1]

Native range

East Asia; introduced to Texas, Maryland, Virginia, Oklahoma, Wisconsin and others. [1]

Size

Up to ~80 kg (ADW range 4.5–80 kg includes young). [1]

Lifespan

15–18 years typical in captivity; record 25+. [1]

Breeding & gestation

~7 months (210 days); fall rut (Sept–Oct); single calf May–June. [1]

Temperament & social structure

Not verified from a primary source for this page.

Habitat needs

Forest deer preferring dense understory; primarily nocturnal. [1]

Where they thrive (Texas / US)

Documented free-ranging in major portions of Kerr, Bandera, Edwards and Real counties (Edwards Plateau/Hill Country). 1988 survey: confined on 207 ranches in 77 counties. See the interactive Texas species map (../site/map.html). [2][3]

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. [4]

Natural diet

Not verified from a primary source for this page.

Feed & supplementation

For supplementation TPWD recommends a 16–20% crude-protein pelleted feed rather than corn (corn is only 7–10% CP). AgriLife cites ~6–7% CP for rumen maintenance and 13–16% CP for growth, antler production and reproduction (white-tailed deer data; applied to exotic deer by analogy). Mineral program: set with a nutritionist/vet; no verified species figure. [5][6][7]

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. [8][9]

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. [10]

Conservation status

IUCN Red List: Least Concern. [11]

Legal notes (general info, not legal advice)

In Texas, exotic CWD-susceptible species (elk, red deer, sika and others) must carry official ID, have movements reported to TAHC within 48 hours, and eligible mortalities tested; TAHC ended its voluntary CWD Herd Certification Program on Sept 16, 2025. 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. [12][13][14][15]
