UTERINE ADENOCARCINOMA IN A PRZEWALSKI'S WILD HORSE (EQUUS FERUS PRZEWALSKII)

Journal of Zoo and Wildlife Medicine, 2014
A 25-yr-old, nulliparous, female Przewalski's wild horse (Equus ferus przewalskii) with a history of pituitary pars intermedia dysfunction and recent onset of serosanguinous vaginal discharge was euthanized after a period of lethargy and inappetance. Postmortem examination confirmed an infiltrative uterine adenocarcinoma, which is an uncommon neoplasia

Note on the Survival Status of Przewalski’s Horse, Equus ferus przewalskii (Perissodactyla: Equidae)

Journal of Ethology & Animal Science
Since, Przewalski’s horses (Equus przewalskii) are not survived in wild, so this is urgent to keep them in captive breeding in any zoos or safari parks. All reports on this horse focused on this same issue.

Ungulate Reintroductions: Experiences with the Takhi or Przewalski Horse (Equus ferus przewalskii) in Mongolia

Conservation Biology, 1996
Experiences with the reintroduction of the takhi, or Przewalski horse (Equus ferus przewalskii, in Mongolia can serve as valuable lessons for reintroduction of ungulates in general. We discuss the present taxonomic, historical, and biological evidence and conclude that the takhi should be viewed as a typical steppe herbivore.

A COMPARISON OF A SINGLE-DART VERSUS STAGED TWO-DART ANESTHESIA INDUCTION PROTOCOL IN PRZEWALSKI'S HORSES (EQUUS FERUS PRZEWALSKII)

Journal of Zoo and Wildlife Medicine, 2021
: Przewalski's horses (Equus ferus przewalskii) are an endangered equid species. Anesthesia administered by remote delivery is often needed to provide medical care. Behavioral and physiologic parameters were prospectively compared in 14 horses (8 females

CLINICAL DISEASE ASSOCIATED WITH ANAPLASMA PHAGOCYTOPHILUM INFECTION IN CAPTIVE PRZEWALSKI'S HORSES (EQUUS FERUS PRZEWALSKII)

Journal of Zoo and Wildlife Medicine, 2017
Anaplasma phagocytophilum is a tick-borne pathogen of domestic horses and the causative agent of equine granulocytic anaplasmosis. This case series describes three confirmed cases of clinical anaplasmosis, and a fourth case of presumptive anaplasmosis in Przewalski's horses ( Equus ferus przewalskii) housed at the Smithsonian Conservation Biology ...

Decision-Making in Przewalski Horses (Equus ferus przewalskii) is Driven by the Ecological Contexts of Collective Movements

Ethology, 2009
AbstractWe addressed decision‐making processes in the collective movements of two groups of Przewalski horses (Equus ferus przewalskii) living in a semi free‐ranging population. We investigated whether different patterns of group movement are related to certain ecological contexts (habitat use and group activity) and analysed the possible decision ...

Oral and injectable synthetic progestagens effectively manipulate the estrous cycle in the Przewalski's horse (Equus ferus przewalskii).

Animal Reproduction Science, 2014
To date, there has been limited research on manipulation of the estrous cycle in endangered equids. The objectives of this study were to assess the efficacy of using combinations of: (a) oral altrenogest and PGF2α, and (b) injectable altrenogest and PGF2α for manipulation of ovarian activity in Przewalski's mares.

ESTABLISHING REFERENCE INTERVALS FOR SERUM INFLAMMATORY MARKERS AND INVESTIGATING THEIR STORAGE STABILITY AND CLINICAL UTILITY IN ASIAN WILD HORSES (EQUUS FERUS PRZEWALSKII) UNDER MANAGED CARE

Journal of zoo and wildlife medicine
: Acute phase proteins (APPs) are commonly used in domestic equine practice, where they rise rapidly in response to inflammation and decrease soon after resolution.

Effects of fly disturbance on the behaviour of a population of reintroduced Przewalski horses (Equus ferus przewalskii) in Mongolia

Applied Animal Behaviour Science, 2010
Abstract Flies constitute a cost to animals by feeding from them, passing on disease or by preventing them feeding effectively. These costs could be more severe to animals suffering from some kind of stress such as reintroduction as part of a conservation programme.

The 24-h time budget of a takh harem stallion (Equus ferus przewalskii) pre- and post-reintroduction

Applied Animal Behaviour Science, 1998
Abstract Focal animal sampling was used to determine the 24-h time budget of a takh harem stallion ( Equus ferus przewalskii ) during the 2 weeks prior to, and the two weeks following, reintroduction into the Hustain Nuruu Steppe Reserve, Mongolia. Both before and after release, the stallion spent approximately 47% of his time grazing, 6% standing ...
