Problems in the Protection of Reintroduced Przewalski's Horses (Equus ferus przewalskii) Caused by Piroplasmosis [PDF]

open access: bronzeJournal of Wildlife Diseases, 2017
The objectives of our research on equine piroplasmosis were to clarify the prevalence of the piroplasms Babesia caballi and Theileria equi among reintroduced Przewalski's horses (takhi, Equus ferus przewalskii) in comparison with horses (Equus caballus) of nomads from around Hustai National Park in Mongolia and to determine the mortality among takhi ...

EQUINE PIROPLASMOSES AT THE REINTRODUCTION SITE OF THE PRZEWALSKI'S HORSE (EQUUS FERUS PRZEWALSKII) IN MONGOLIA [PDF]

open access: bronzeJournal of Wildlife Diseases, 2006
Piroplasmosis has been identified as a possible cause of mortality in reintroduced Przewalski's horses (Equus ferus przewalskii) in the Dsungarian Gobi (Mongolia). A cross-sectional and a longitudinal study were conducted in a representative sample (n = 141) of the resident domestic horse population and in 23 Przewalski's horses to assess the ...

Seasonal adjustment of energy budget in a large wild mammal, the Przewalski horse (Equus ferus przewalskii) II. Energy expenditure [PDF]

open access: bronzeJournal of Experimental Biology, 2006
SUMMARY Many large mammals show pronounced seasonal fluctuations of metabolic rate(MR). It has been argued, based on studies in ruminants, that this variation merely results from different levels of locomotor activity (LA), and heat increment of feeding (HI).

Improved sperm cryosurvival in diluents containing amides versus glycerol in the Przewalski’s horse (Equus ferus przewalskii) [PDF]

open access: greenCryobiology, 2014
Two studies were conducted to understand sperm cryosensitivity in an endangered equid, the Przewalski's horse (Equus ferus przewalski), while testing the cryoprotectant ability of formamides. The first assessed the toxicity of permeating cryoprotectants (glycerol, methylformamide [MF] and dimethylformamide [DMF]) to Przewalski's horse spermatozoa ...
