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 ...

Understanding the reproductive biology of the Przewalski's horse (equus ferus przewalskii) [PDF]

, 2010
The Przewalski's horse (Equus ferus przewalskii) once roamed the Eurasian Steppe but is now considered Critically Endangered with only 1872 individuals remaining in the world, representing progeny from only 14 founder animals (Lee and Boyd, 2008). Genetic diversity needs to be optimal for long term survival of this species.

PITUITARY PARS INTERMEDIA DYSFUNCTION (EQUINE CUSHING'S DISEASE) IN NONDOMESTIC EQUIDS AT MARWELL WILDLIFE: A CASE SERIES. ONE CHAPMAN'S ZEBRA ( EQUUS QUAGGA CHAPMANI) AND FIVE PRZEWALSKI's HORSES ( EQUUS FERUS PRZEWALSKII).

Journal of Zoo and Wildlife Medicine, 2018
Pituitary pars intermedia dysfunction (PPID), also known as equine Cushing's disease, is widely reported in middle-aged to older domestic equids but to date reported in only one nondomestic equid, the onager (Equus hemionus onager).

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

Intestinal parasites in Przewalski's horses (Equus ferus przewalskii): a field survey at the Hortobágy National Park, Hungary

Journal of Helminthology, 2021
Abstract The Pentezug Wildhorse Reserve, located in the Hortobágy National Park, Hungary, has one of the biggest ex situ populations of Przewalski's horses and aims to preserve its landscape and to study this subspecies. Between September and November 2018, 79 faecal samples were collected from Przewalski's horses.

Water consumption and watering behavior of Przewalski horses (Equus ferus przewalskii) in a semireserve

Zoo Biology, 1998
Water consumption by 12 female Przewalski horses was automatically measured in a semireserve for 17 months. Average daily consumption on a yearly basis was between 2.4 and 8.3 liters, but significant individual variation in water consumption and drinking frequency was recorded throughout the observation period.

ACUTE PHASE PROTEINS AS A MARKER OF RESPIRATORY INFLAMMATION IN PRZEWALSKI'S HORSE (EQUUS FERUS PRZEWALSKII)

Journal of Zoo and Wildlife Medicine, 2016
Acute phase proteins are sensitive markers of inflammation, which are highly conserved across taxa. Although the utility of these proteins are becoming well defined in human and domestic animal medical fields, their role in nondomestic species remains unclear.

SURVEY OF ANAPLASMA PHAGOCYTOPHILUM ANTIBODIES IN CAPTIVE PRZEWALSKI'S HORSES (EQUUS FERUS PRZEWALSKII)

Journal of Zoo and Wildlife Medicine, 2017
Anaplasma phagocytophilum (formerly Ehrlichia equi ) is a tickborne pathogen of domestic horses and the causative agent of equine granulocytic anaplasmosis. After the occurrence of clinical anaplasmosis in a Przewalski's horse ( Equus ferus przewalskii) housed at the Smithsonian Conservation Biology Institute in 2008, opportunistic serosurveillance of ...

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 and 6 males, 3-18 yr) after a single-dart or staged two-dart anesthesia induction protocol with ...
