Abstract:
Strongylid Community Structure of the Przewalski's Horses (Equus ferus Przewalskii) from the Biosphere Reserve "Askania-Nova", UkraineSpecies composition and the structure of strongylid community of the Przewalski's horse (Equus ferus przewalskiiPoljakov, 1881) semi-free population at the "Askania-Nova" Biosphere Reserve were studied by thein vivomethod of diagnostic deworming. After deworming of 24 adult Przewalski's horses by the anthelmintic "Univerm" (0.2% aversectin C, Russia), 25,815 strongylid specimens were collected and identified. Thirty-one strongylid species of 12 genera were found including 6 species of the subfamily Strongylinae and 25 — of Cyathostominae. Nine to 18 strongylid species (average 14.5 ± 2.5) were found per horse. Cyathostomes (Cyathostominae) dominated in the Przewalski's horse strongylid community: 9 species (Cyathostomum catinatum, C. pateratum, Cylicocyclus nassatus, C. insigne, C. leptostomum, C. ashworthi, Cylicostephanus longibursatus, C. goldi and C. minutus) were found in more than 80% of horses examined and composed 94.1% of the total number of strongylid collected. Strongyles (Strongylinae) were found in 100% of theE. ferus przewalskiiexamined; prevalence of separate species was from 4.2% to 58.3%. The general structure of the strongylid community was multimodal with dominant (9 species), subdominant (4), background (4) and rare (14) species. The list of strongylid species found in the Przewalski'si horses in Ukraine was enlarged to 37 species.

Abstract:
In thoroughbred horses, red blood cell amino acid transport activity is Na+-independent and controlled by three codominant genetic alleles (h, l, s), coding for high-affinity system asc1 (L-alanine apparent Km for influx at 37 °C [Formula: see text] 0.35 mM), low-affinity system asc2 (L-alanine Km[Formula: see text] 14 mM), and transport deficiency, respectively. The present study investigated amino acid transport mechanisms in red cells from four wild species: Przewalski's horse (Equus przewalskii), Hartmann's zebra (Zebra hartmannae), Grevy's zebra (Zebra grevyi), and onager (Equus hemonius). Red blood cell samples from different Przewalski's horses exhibited uniformly high rates of L-alanine uptake, mediated by a high-affinity asc1-type transport system. Mean apparent Km and Vmax values (± SE) for L-alanine influx at 37 °C in red cells from 10 individual animals were 0.373 ± 0.068 mM and 2.27 ± 0.11 mmol (L cells∙h), respectively. As in thoroughbreds, the Przewalski's horse transporter interacted with dibasic as well as neutral amino acids. However, the Przewalski asc1 isoform transported L-lysine with a substantially (6.4-fold) higher apparent affinity than its thoroughbred counterpart (Km for influx 1.4 mM at 37 °C) and was also less prone to trans-stimulation effects. The novel high apparent affinity of the Przewalski's horse transporter for L-lysine provides additional key evidence of functional and possible structural similarities between asc and the classical Na+-dependent system ASC and between these systems and the Na+-independent dibasic amino acid transport system y+. Unlike Przewalski's horse, zebra red cells were polymorphic with respect to L-alanine transport activity, showing high-affinity or low-affinity saturable mechanisms of L-alanine uptake. Onager red cells transported this amino acid with intermediate affinity (apparent Km for influx 3.0 mM at 37 °C). Radiation inactivation analysis was used to estimate the target size of system asc in red cells from Przewalski's horse. The transporter's in situ apparent molecular weight was 158 000 ± 2500 (SE).Key words: amino acid transport, erythrocyte, Przewalski's horse.

Abstract:
Efforts are under way to re-establish free-living populations of Przewalski's horse Equus przewalskii from zoo-bred individuals. The time is opportune to begin such initiatives as there are more than 660 individuals dispersed in over 70 zoological collections. In addition, the captive population is now increasing rapidly and has the potential to provide reasonable numbers of animals for reintroduction programmes without jeopardizing the maintenance of the population that serves as an ex-situ gene pool nucleus.

Abstract:
Reintroduction of an endangered species or subspecies is only the first step towards ensuring survival and population increase. The first phase of takhi (Equus ferus przewalskii) reintroductions has been successful, but populations remain at risk from isolation, resource competition with humans and livestock, and hybridisation with modern domestic horses. Greater social cohesion in takhi family groups reduces the risk of individual and group isolation and of hybridisation, which in turn increases the integrity and vigour of reintroduced populations. The aim of this study was to investigate potential behavioural mechanisms of social cohesion in reintroduced takhi, exploring mechanisms of cohesion both within and between family groups. Interindividual spatial distribution served as a surrogate measure of cohesion, and potential mechanisms included interindividual interactions and differences in individual reproductive state, personality, and group membership. Social network analysis was used to identify classes of takhi significantly central to spatial and interaction networks. Two repeatable personality traits were detected (sociability and assertiveness), but reproductive state had a stronger influence on cohesion than did personality. Mares were the most active managers of intragroup spatial distribution. Stallions were the most active managers of intergroup cohesion. Stallions and colts were most active in intergroup affiliative networks. Overall, reproductive state most clearly dictated individual involvement in interactions influencing intra- and intergroup cohesion, while group membership and personality influenced intergroup spatial cohesion. This study is the first to incorporate personality assessment and fine-scale spatial data into an investigation of Type I equid social structure in naturally established, free-living takhi family groups. Future takhi management efforts should focus on monitoring interstallion relationships, colt social development, and filly dispersal as the primary sources of variation and changes in group and herd level cohesion in takhi populations. Results of this study can be applied to adaptive management of takhi populations, and groups and herds of other Type I equids, including feral and domestic horses.

Abstract:
Studies on the behavioural ecology of Przewalski horses (Equus przewalskiiy) recently reintroduced into Hustai National Park, Mongolia were carried out between 1998 and 2000. Home range size and habitat use, social, marking, and vigilance behaviour, and their reaction to flies were quantified. Home ranges of harems ranged from 129 ha to 2399 ha, with core areas of between 61 ha and 1196 ha. There was no relationship between range size and harem size, or length of time since release. The more nutritious vegetation at lower elevations was preferentially selected. The horses rested near ridges during the hotter parts of the day where there were fewer flies, and grazed in the valleys in the mornings and evenings. Woodland areas were used to shelter from the sun, despite their high fly abundance. Muscid flies were most frequently caught; Tabanids were rare. Dominance was related to age, aggression and length of time in the harem. The frequency of associative behaviours did not correlate with any social factor, but had a hygienic function. Stallions marked stud piles wid mare eliminations in different ways suggesting different functions. In addition to being vigilant for predators, the horses appeared to scan for social cues and food patches. Home range size and habitat use, and general pattern of marking and vigilance behaviour, of the wild Przewalski horses were similar to those seen among feral domestic horses, although they tended to be less aggressive than captive and feral horses. So far, the re-establishment of przewalski horses into HNP appears to have been successful, although constant monitoring of the population is necessary. As the population grows, there will be potential problems to do with exceeding the carrying capacity of the park and hybridisation with domestic horses. The future management of the horses is discussed.

Abstract:
Dissertação de Mestrado Integrado em Medicina Veterinária<br>Equus ferus przewalskii, currently assumed as subspecies of E. ferus, is considered as endangered by the International Union for Conservation of Nature (IUCN). The ex situ conservation has been crucial for the continued preservation of this subspecies, once considered extinct in the wild. The Pentezug Wildhorse Reserve, located in the Hortobágy National Park, in Hungary, has one of the biggest ex situ populations of Przewalski’s horses and it’s aimed to preserve its typical landscape and to study wild horses in a semi-wild habitat, making part of this subspecies reintroduction plan. Currently, this population comprises almost 280 Przewalski's horses, sharing the area with a population of domestic cattle (Bos primigenius taurus), carefully bred to reconstructed aurochs (Bos primigenius). In this study, 79 faecal samples were collected and the coprological methods (McMaster, Willis floatation, natural sedimentation, Baermann and coproculture) and corresponding microscopic identification were performed in all the samples. Results show an average level of 1286.7 Eggs per Gram (EPG), which is considered a high level of parasitism. All the 79 samples analysed were positive for strongylid-type eggs (100% prevalence) (79/79), with a dominance of the cyasthostominae, when compared to strongylinae and tricostrongylidae. Moreover, a total of 15 different morphological L3 types and/or species identified of the order Strongylida. Additionally, 27.8% (22/79) were positive to Parascaris sp. and 2.5% (2/79) contained Oxyuris equi in their expelled faeces. By the sedimentation method, we could only evidence a Trematoda egg (1/79). In the subfamily Cyathostominae, L3 of cyathostomins type A showed 100% prevalence. In Strongilinae, Strongylus vulgaris is the most prevalent (40.5%), followed by Triodontophorus serratus (12.7%). These results are consistent with the other studies performed in the same subspecies and represent the first survey of gastrointestinal parasites performed with this level of detail in this population of Przewalski’s horses. Statistically, this study revealed that animals infected by Parascaris spp. tend to be positive in association with cyathostomins type C. In the same way, animals infected by T.serratus tend to be positive for Poteriostomum spp., possibly due to the propensity of juveniles for these two parasites revealed in this study. Furthermore, males have more S. vulgaris infections than females and animals infected by S. vulgaris tend to have lower levels of EPG. These results reveal the importance of parasite monitoring in wild ex situ populations, especially those that can be part of a reintroduction program, to better-knowing their pathogenic potential, possible parasite associations, predisposition factors and consequences for the subspecies conservation.<br>RESUMO - Parasitas gastrointestinais em cavalos de Przewalski (Equus ferus przewalskii), na reserva de cavalo selvagem do Pentezug, Parque Nacional de Hortobágy, Hungria - Equus ferus przewaslkii é classificada como uma subespécie de E. ferus. Presentemente, encontra-se em perigo, segundo a União Internacional para a Conservação da Natureza (IUCN), apesar de já ter assumido o estatuto de Extinta na Natureza. Por este motivo, a conservação ex situ tem tido um papel crucial na conservação desta subespécie. A reserva de cavalo selvagem do Pentezug, inserida no parque nacional de Hortobágy, na Hungria, tem uma das maiores populações ex situ de cavalo de Przewalski, com os principais propósitos de conservar a paisagem característica da região e aprofundar os conhecimentos sobre a subespécie, fazendo parte do seu programa de reintrodução. Atualmente, esta população é composta por cerca de 280 cavalos de Przewalski, que partilham a pastagem com uma população de bovinos domésticos (Bos primigenius taurus), selecionada de forma a apresentar um fenótipo semelhante ao auroque (Bos primigenius). Foram colhidas 79 amostras fecais e os métodos coprológicos (McMaster, flutuação de Willis, sedimentação natural, Baermann e coprocultura) e a respetiva identificação microscópica foram executados para todas as amostras. Os resultados demonstraram um nível de parasitismo médio de 1286,7 ovos por grama (OPG), o que representa um valor elevado. Todas as amostras foram positivas para ovos do tipo estrongilídeo (100% de prevalência) (79/79), com uma dominância dos ciatosmíneos, comparando com estrongílideos e tricostrongilídeos, e revelaram uma diversidade de 15 espécies ou morfotipos de L3 dentro da ordem Strongylida. Adicionalmente, 27,8% (22/79) foram positivas para Parascaris sp., 2,5% (2/79) dos animais continham Oxyuris equi nas fezes expelidas e numa amostra foi detetado um ovo de trematode (1/79). As L3 de ciatostomíneos de tipo A revelaram uma prevalência de 100%. Na subfamília Strongilinae, Strongylus vulgaris foi o mais prevalente (40.5%), seguido de Triodontophorus serratus (12,7%). Estes resultados são consistentes com outros estudos efetuados na espécie e representam o 1º estudo parasitológico na população de Pentezug, realizado com este nível de detalhe. Estatisticamente, este estudo revelou que animais positivos a Parascaris spp. tendem a ser positivos para ciatostomíneos do tipo C. O mesmo acontece entre T. serratus e Poteriostomum spp., possivelmente devido à predisposição dos juvenis para estes dois parasitas revelada neste estudo. Do mesmo modo, os machos têm mais infeções por S. vulgaris do que as fêmeas e os animais positivos para este parasita tendem a ter níveis mais baixos de OPG. Estes resultados demonstram a importância da monitorização parasitológica em populações ex situ, especialmente as que fazem parte de um programa de reintrodução, com o objetivo de aprofundar o conhecimento sobre o poder patogénico dos agentes, possíveis coinfeções, fatores de risco e consequências para a conservação da subespécie.<br>N/A

Abstract:
Einleitung Huferkrankungen nehmen einen hohen Patientenanteil in der orthopädischen Pferdepraxis ein. Sie sind häufig begleitet von geringem Hornwachstum und/oder ständigen Tragrandausbrüchen. Hierbei stellt sich die Frage, in wie weit dieses Geschehen durch die jeweilige Pferdehaltung begünstigt wird und wie stark der genetische Einfluss hierauf ist. Vom einzigen rezenten Wildpferd, dem Przewalskipferd, sind Daten zum Hornwachstum und -abrieb mit ausgeprägter Saisonalität bekannt, außerdem existiert bei Haltung im Semireservat ein spezieller Mechanismus des Tragrandausbruches. Diese Faktoren führen zu einer selbstständigen Huflängenregulation ohne Einflussnahme des Menschen. Ziele der Untersuchungen Die Untersuchungen dienen dem Ziel, für das Hauspferd Daten über saisonale Hornproduktion und Hornabnutzung zu erheben und Aussagen über einen eventuell vorhandenen physiologischen Huflängenregulationsmechanismus (wie er auch bei den Przewalskipferden vorkommt) zu machen. Eine suffiziente Ausprägung eines solchen Mechanismus ist für die tierschutzgerechte Durchführung einer Haltungsform, bei der die Pferde weitgehend sich selbst überlassen sind, essentiell. Durch den Vergleich mit dem Przewalskipferd sollen außerdem genetische und umweltbedingte Einflüsse auf die Huflängenregulation geklärt werden, um die Kenntnisse der für eine extensive Pferdehaltung nötigen Umweltfaktoren zu verbessern und zu erweitern. Materialien und Methoden Für die Untersuchungen standen insgesamt 26 Liebenthaler Pferde (Hauspferde) unterschiedlichen Alters (12 Pferde vor 1999 geboren, 14 Pferde ab 1999 geboren) und Geschlechtes (11 Hengste, 15 Stuten) zur Verfügung, die in Semireservat-ähnlicher Haltung leben. Bei diesen Tieren wurden über einen Zeitraum von einem Jahr an jedem Huf in monatlichem Abstand die Länge des Rückenteils der Hufplatte, die Hornbildung, der Hornverlust sowie das Auftreten von Hornspalten und Hornchips erfasst. Die Messungen der Dorsallänge sowie der monatlichen Hornbildung und des monatlichen Hornverlustes wurden direkt an den Hufen der untersuchten Pferde durchgeführt, wobei zur Erfassung von Hornbildung und Hornverlust der Distalschub einer artifiziell angebrachten Markierung an der dorsalen Hufwand erfasst wurde. Die auftretenden Hornspalten und Hornchips wurden monatlich fotografisch dokumentiert und im Anschluss nach ihrer Ausdehnung und Lokalisation ausgewertet. Für die Aussagen im Ergebnisteil wurden Methoden der deskriptiven und explorativen Statistik angewendet (Berechnung von Mittelwerten, Streuungsmaßen, Korrelationen, Darstellung linearer zusammenhänge mittels Regressionsgeraden, Varianzanalysen, Scheffé-Test). Ergebnisse Die dorsale Huflänge unterliegt bei den Liebenthaler Pferden einer Regulation, die es ermöglicht, sie nach Ausbildung ihrer individuellen Größe innerhalb einer gewissen Spannweite auch über Jahre hinweg konstant zu halten. Die Dynamik im Jahreszyklus äußert sich mit Höchstwerten im Mai und Minimalwerten im August. Dieses ist bedingt durch die im Verlauf der Jahreszeiten unterschiedlichen Werte bei Hufhornbildung und -verlust. Im Sommer sind sowohl die Hornproduktion als auch der Hornverlust signifikant höher als in den kälteren Monaten. Obwohl Hornbildungsrate und Hornverlust eine positive Korrelation zueinander aufweisen (r = 0,47), lassen sich auch Unterschiede erkennen: im Frühling und Sommer überwiegt der Hornverlust, während sich im Herbst und Winter eine höhere Hornbildung nachweisen lässt. Für die Abnutzung des Hufhorns gibt es zwei sich ergänzende und saisonal unterschiedlich stark wirkende Mechanismen: den Hufhornabrieb und die Tragrandausbrüche als Endergebnis des Chippings. Der Hornabrieb wird vor allem durch die Untergrundhärte gefördert und tritt zu allen Jahreszeiten mit Höchstwerten im Sommer und Minimalwerten im Winter auf. Das Auftreten von Tragrandausbrüchen und den sie bedingenden Hornchips ist vor allem auf die Sommermonate konzentriert, während in den kälteren Jahreszeiten nur wenige und kleinere Ausbrüche stattfinden. Der Prozess des Chippings wird eingeleitet durch die Bildung von Hornspalten im Tragrandbereich zwischen denen es dann durch Spreiz- und Hebelwirkung beim Auffußen zur Bildung eines Querrisses mit anschließender vollständiger Separierung eines Hornchips kommt. Der Tragrand wurde im Ergebnis dieses Ausbruchs auf das Niveau der Hufsohle eingekürzt. Die meisten Hornchips treten in Übereinstimmung mit der Ausbildung von Hornspalten an der lateralen Hufseite auf, außerdem werden die Vorderhufe deutlich öfter durch Tragrandausbrüche verkürzt als die Hinterhufe. Die Bildung von Hornspalten ist in der untersuchten Population deutlich höher, als es für einen regelrechten Chipping-Vorgang nötig wäre. Schlussfolgerungen Für die Liebenthaler Pferde wird die Schaffung von Bereichen mit abrasiven Untergründen auf dem ansonsten mit weichem Boden bedeckten Weidegelände empfohlen, um das häufige Auftreten von durchgehenden Hornspalten (mit der damit verbundenen Gefahr von Schmerz und Lahmheiten) zu minimieren. Bei einem Vergleich mit unter ähnlichen Bedingungen gehaltenen Przewalskipferden lässt die Höhe von Hornbildungsrate und Hornverlust einen genetischen Einfluss auf diese Parameter vermuten. Die Ausprägung der saisonalen Unterschiede ist jedoch bei beiden Rassen gleich, so dass für diese am ehesten die Habitatbedingungen als auslösende Faktoren in Betracht kommen. Beim Liebenthaler Pferd stellt sich eine dem Przewalskipferd ähnliche Längenregulation am Huf ein, wobei einzelne hierfür notwendige Mechanismen auch Unterschiede aufweisen. Somit wird deutlich, dass die Grundlage für eine physiologische Selbsterhaltung der Huflänge die den Pferden angebotenen Haltungsbedingungen sind, während die Genetik und die Domestikation geringere Effekte auf die Längenregulation haben. Auftretende pathologische Erscheinungen (nicht nur am Huf) müssen jedoch auch bei Extensivhaltung der Pferde zur Landschaftspflege erkannt und behandelt werden.

Abstract:
Вследствие развития коневодства в Среднем Прииртышье в период с ~3,5 тыс. лет до н.э. по XIX в. н.э. произошло вытеснение за пределы территории и уничтожение диких лошадей (степного тарпана, лошади Пржевальского, казахстанского кулана). Дикие лошади составляли конкуренцию домашним лошадям за естественные пастбища и мешали ведению отгонного коневодства. Due to the development of horse breeding in the middle Irtysh in the period from about 3.5 thousand years BC to the XIX century it was a displacement outside the territory and the destruction of wild horses (steppe Tarpan, Przewalski’s horses, Kulan Kazakhstan). Wild horses competed with domestic horses in natural pastures and prevented the maintenance of pasture breeding.

Abstract:
One of the significant risks in the introduction of animals is their infection with helminths. In 2020 in the steppe hospital “Orenburg Tarpaniya” a survey of Przhevalsky’s horses and kiangs for helminthiasis was carried out. Parasitism of nematodes of the suborders Strongylata, Ascaridata and Oxyurata was revealed at low and medium intensity of invasion. Nematode infestation is higher in Przewalski’s horses than in Kiangs. These helminthiases proceeded in the form of carriage.
