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.

Zusammenfassung Das Ziel dieser Studie war, das Verhalten von Przewalskipferden bei hoher Besatzdichte in einer Junggesellengruppe auf einer Flache von 3,5 ha zu untersuchen. Die Gruppe bestand aus 16 mannlichen Tieren im Alter von 5 bis 16 Jahren. Verhaltensdaten wurden uber 18 Tage gesammelt, insgesamt 216 h.

Abstract In equines, calls given by foals or mothers when they are seeking contact with each other or by stallions seeking contact with other group members could be classified as affiliative or separation calls when a reunion follows the vocalizations. To investigate how domestication can affect the characteristics of vocalizations produced by equines,

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.

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 ...

Note on the Survival Status of Przewalski’s Horse, Equus ferus przewalskii (Perissodactyla: Equidae)
Journal of Ethology & Animal ScienceSince, 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. In nature, the sole enemy of this horse is Himalayan wolf (Canis lupus chanco), so in captivity through proper management, the breeding schedule ...

ENHANCED EQUUS FERUS PRZEWALSKII OPTIMIZATION AND ADVANCED OSTEOLAEMUS SEARCH ALGORITHM
Suranaree Journal of Science and TechnologyWe apply the enhanced Equus Ferus Przewalskii optimization (EEPO) algorithm and the advanced Osteolaemus search optimization (AOSO) algorithm to solve true power loss reduction problems. Equus Ferus Przewalskii tends to pursue and run in its environment. As a result, the adult Equus Ferus Przewalskii and steeds adopt an arbitrary course.

Analysing animal movement reveals how animals interact with their environment and is necessary to understand their foraging behaviour. Due to landscape heterogeneity, species differences, various resource selection and physical features animals show various movement tactics.

The 24-h time budget of a takh harem stallion (Equus ferus przewalskii) pre- and post-reintroduction
Applied Animal Behaviour Science, 1998Abstract 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 ...
