Overview
Yak appears on the Exotic Wildlife Association species list as Yak — ESA: Not Listed; CITES: Appendix I. [1]
Native range
While their domesticated counterparts can be found in a much more varied area in the oriental region, the main geographic range of wild B. grunniens is limited to the Tibetan Plateau, which includes "...the western edge of Gansu Province, Qinghai Province, the southern rim of the Xinjiang…. [2]
Size
300–1,000 kg (ADW range). [2]
Lifespan
25 years (wild, range). [2]
Breeding & gestation
Gestation average 9.33 months; offspring per birth: 1; females mature at 6 to 8 years. [2]
Temperament & social structure
Not verified from a primary source for this page.
Habitat needs
The habitat of B. grunniens can vary, but mainly consists of three areas with different vegetation: Alpine meadow, alpine steppe, and desert steppe. ADW biomes: mountains, tundra. Elevation range 3200–5400 m. [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
Bos grunniens is a grazer, with a diet composed mainly of various low-lying grasses and grass-like plants, including shrubs, forbs, cushion plants, etc., found on the Tibetan plateau, though they will also consume lichen, mosses, and forbs. 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: Domesticated form (not assessed separately); wild yak (Bos mutus): Vulnerable. [9]
Legal notes (general info, not legal advice)
CITES Appendix I (per the EWA list); international trade needs CITES permits. 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]
