“…In temperate climates, adherence to adequate hygiene standards decreases the number of infective larvae in pastures, lowers the risk of infection and minimizes the use of anthelmintics (2,7,(12)(13)(14)31). Suitable farm management practices combined with the rational use of drugs preceded by parasitological examinations of faecal samples reduce the selection pressure for anthelmintic resistance.…”

SummaryVirtually all horses in Poland periodically receive deworming treatment. In view of the emerging anthelmintic resistance it is important to know the current parasite control practices used by Polish horse owners. In order to assess the situation and analyze it in terms of the risk of drug resistance, a questionnaire survey was forwarded to 300 horse establishments. The response rate was 49.6%. The average number of deworming treatments in adult horses was determined at 2.1. and 2.8 for youngstock per calendar year. The most commonly used drugs were ivermectin, pyrantel pamoate and moxidectin. Almost 73% of respondents indicated that they take into consideration the resistance of parasites. However, only 4.03% of the responders regularly send faecal samples from all horses for parasitological examination. In ca. 92% of cases the person administrating the drug guessed the weight of the horse by visual evaluation. Generally, little attention was paid to pasture hygiene and prevention of parasitic infection. The responses indicate a high level of awareness among horse owners of the need to control parasites. They also show the large involvement of veterinarians as a source of advice about deworming practices, so we concluded that the most appropriate way to achieve improvement would be implementation of further education programmes for veterinarians.

-A questionnaire survey regarding endoparasite control practices in Danish horse herds was carried out in 1995. The participating veterinarians and herd owners were sampled using convenience and purposive sampling. In the analysis of risk factors for development of a high endoparasitic burden (>200 eggs per gram faeces) 903 horses were sampled and the analysis of the efficiency of a single anthelmintic treatment was based on 605 horses. The following factors had a significant effect on the endoparasitic burden: herd type, age of the horses, use of pasture rotation, anthelmintic treatment of horses visiting the herd, use of an adviser in the planning of endoparasite control and advice regarding pasture rotation. An interaction between pasture rotation and advice regarding pasture rotation was found, but due to high collinearity this was not reported. The factors influencing significantly on the reduction of the faecal egg count after a single anthelmintic treatment were the type of herd, the age of the horse, the drug used, and the anthelmintic-resistance-status of the herd. A negative effect of permanent pastures was observed. If pasture hygiene was performed on the advice of the veterinarian, the effect of a single anthelmintic treatment was less compared to a single anthelmintic treatment without any advice. An interaction between the treatment group and the resistance-status of the herd was found. Additional factors, normally accounted for, when endoparasites and anthelmintic resistance is discussed, were investigated, but not found significant in this study. endoparasites; epidemiology; anthelmintic resistance.

“…Cross-infection between ruminants and equids must have occurred at a later time when, after the Przewalski's horse range expansion, their respective habitat overlapped. T. axei, primarily a ruminant abomasal parasite (Schnieder et al 2006;Elias et al 2002), only occurs in equid species grazing on the same pastures as ruminants (Eysker et al 1986). The most common wild ruminant in the Great Gobi "B" is the black-tailed gazelle.…”

Comparative parasitological examination on sympatric equids in the Great Gobi “B” Strictly Protected Area, Mongolia

et al. 2010

The Przewalski's horse (Equus caballus przewalskii) became extinct in the wild during the 1960s. Based on a successful captive breeding program, Przewalski's horses were reintroduced to the Great Gobi Part "B" strictly protected area (SPA) in SW Mongolia in the late 1990s. The Asiatic wild ass (Equus hemionus hemionus), Przewalski's horse, and sometimes domestic horses live sympatricly in the Gobi B SPA. Previously published data demonstrates that, as a result of their different requirements and utilization of the park's resources, their home-range size and social structure differ. Parasitological examinations in the three equid species show how the factors "home range, social structure, and resource selection" significantly impact parasitic burden. Asiatic wild asses are potentially exposed to a higher risk of parasite re-infection due to their temporal aggregation in very large groups. This study demonstrates a highly significant greater parasite load in the Asiatic wild ass for the majority of parasites evaluated (Dictyocaulus arnfieldi, Trichostrongylus axei, Strongyloides westeri, Parascaris equorum) compared to Przewalski's horses and domestic horses in the same habitat. Domestic horses had higher parasite loads for eggs of strongylids, eggs of anoplocephalidae, and Eimeria leuckarti. The potential risk of cross infection between sympatric living equids is high, as is the cross infection between ruminants and equids. Furthermore, this study reports for the first time the occurrence of lungworms in free-ranging Przewalski's horses. Whereas, Asiatic wild asses and Przewalski's horses seem to cope very well with the sometimes high parasite burden, Mongolian domestic horses manifested typical parasite burden symptoms.
