Overview
Pronghorn appears on the Exotic Wildlife Association species list as Pronghorn — ESA: Not Listed; CITES: N/A. [1]
Native range
Antilocapra americana is endemic to North America and distributed throughout the treeless plains, basins, and deserts of western North America, from the southern prairie provinces of Canada, southward into the western United States and to northern Mexico. [2]
Size
47–70 kg (ADW range). [2]
Lifespan
16 years (wild, average); 11 years (captivity, range); 11.8 years (captivity, average). [2]
Breeding & gestation
Gestation average 252 days; offspring per birth: 1–2; females mature at 5 months. [2]
Temperament & social structure
Not verified from a primary source for this page.
Habitat needs
Pronghorns are primarily found in grassland, sage scrub or chapparal, and desert. The southern portion of their range consists mainly of arid grasslands and open prairies. ADW biomes: desert or dune, savanna or grassland, chaparral. Elevation range 0–3,350 m. [2]
Where they thrive (Texas / US)
Antilocapra americana is endemic to North America and distributed throughout the treeless plains, basins, and deserts of western North America, from the southern prairie provinces of Canada, southward into the western United States and to northern Mexico. [2]
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
Pronghorns are herbivores, eating stems, leaves, grasses and shrubs. Pronghorns have been described as "dainty" feeders, feeding on small amounts of a wide variety of plants. ADW diet type: herbivore, folivore. [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: Least Concern. [9]
Legal notes (general info, not legal advice)
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. [10][11]
