The Organization of Estonian energetic economy is aimed at cutting the usage of oil, gas and coal and increasing the local resources firewood, oil-shale and peat for fuel. The resources of low-valued firewood-brushwood, fallen deadwood etc. are available during the following 10-15 years, but in the future the cultivation of energy forest (willow) plantations will be actual. During the last 20 years the Swedish scientists have been extensively studying the willow forest selection, cultivation and use in energetics and waste water purification systems. A Swedish-Estonian energy forest research project was started in 1993 between the Swedish Agricultural University on one hand and Toravere Observatory, Institute of Zoology and Botany, Estonian Academy of Sciences and Estonian Potato Processing Association on the other hand. In spring 5 willow plantations were established with the help of Swedish colleagues and obtained from Sweden 36000 willow cuttings. The aim of the project: a) To study experimentally and by means of mathematical modelling the biogeophysical aspects of growth and productivity of willow plantations in Sweden and Estonian climatological conditions. b) To study the possibility of using the willow plantations in waste waters purification. c) To study the economical efficiency of energy forest as an energy resource under the economic and environmental conditions of Estonia. d) To study the economic efficiency of willow plantations as a raw material for the basket industry in Estonia. e) To select the most productive and least vulnerable willow clones for practical application in energy plantations. During 1993 in all five plantations detailed analysis of soil properties has been carried out. In the plantation at Toravere Observatory phytometrical measurements were carried out - the growth of plant biomass leaf and stem area, vertical distribution of dry matter content, biomass and phyto area separately for leaves and stems has been performed.

Estonian horticultural peat marketing: sales promotion and price formation. 2. part

International Nuclear Information System (INIS)

Hammer, Hele

1999-01-01

When forming prices, Estonian peat companies' decisions should be based on marginal cost analysis. Unfortunately most Estonian companies sell peat to intermediaries and cannot influence its price. Estonian peat producers have to choose between either selling peat directly or selling through a central marketing organization. Both systems have their pros and cons. Direct selling gives more freedom to individual producers but is more risky. Central marketing makes cost saving possible and is more effective and stable, but may alienate producers from clients and markets. Whichever marketing system Estonian peat companies choose, the most important elements in their marketing strategy should be: careful market analysis, personal sales, attending trade shows, catalogues, quality service and offering transportation services.

2015-06-01

Full Text Available Purpose – The study is a contribution to the validation of the 15 items and 5 subscales Transformational Leadership Scale (TLS proposed by Rafferty and Griffin (2004. Design/methodology/approach – The sample includes participants from different levels of the Estonian Defence Forces (EDF military hierarchy (N=2570. The structure of the TLS was examined by using exploratory and confirmatory factor analyses. Additionally ANOVA was used to compare the results between different subsamples. Findings – TLS showed satisfactory reliability. Confirmatory factor analyses found TLS as valid five dimensions instrument to measure transformational leadership in the Estonian military context. Different management levels showed different emphases among the dimensions of transformational leadership. Research and practical limitations/implications – TLS will be an important tool to use in transformational leadership research in the Estonian military context and beyond. Additionally, the current research contributes to the development of alternative measurement tools besides the most commonly used MLQ. The limitation of the work will be the rather homogenous sample from the Estonian military, however it will open the door for the subsequent research using different samplings. Originality/value – The current research found TLS to be a reliable and valid instrument, very short and therefore easy to administrate, having the possibility to use it with five dimensional and as one general transformational instrument as well.

Uniting the Divided Continent. The Estonian National Committee of the European Movement

Pauli Heikkilä

2010-12-01

Full Text Available The article examines the exiled Estonian politicians in the European Movement in the early Cold War period. The ultimate goal of exiled Estonians was to restore their state’s independence. In order to promote this, Estonian leaders sought connections with Western leaders. The European Movement was the only organisation involving actors from both the East and the West, and this corresponded to the Estonian discourse on Europe as a whole. Therefore, the European Movement was appreciated, although its limited opportunities for decisive actions were also recognised. East and West European interest in the European Movement declined as West European integration rapidly intensified through the European Coal and Steel Community (ECSC and particularly after the January 1952 Eastern European Conference in London. By 1957, disappointment in the inability of European unification to help regain Estonian independence became evident.

Genetic structure of three Croatian horse breeds: implications for their conservation strategy

Directory of Open Access Journals (Sweden)

Miljenko Konjačić

2010-01-01

Full Text Available The genetic variability for a sample of 107 animals from three autochthonous Croatian horse breeds was estimated using 20 microsatellites. The average number of alleles per locus (6.3 and proportion of heterozygosity (0.732 indicated a moderate variability. The expected heterozygosity was similar among all breeds and ranged between 0.724 in the Posavina horse, and 0.737 in the Croatian Coldblood and Murinsulaner horse. The inbreeding coefficient FIS was low and non-significant over the three populations. The genetic differentiation among the three populations was low (FST=0.026, suggesting that only 2.6% of the total genetic variability was due to differences between the breeds, and 97% to individual differences. The results of pairwise genetic differentiation suggest that the Posavina horse and the Croatian Coldblood were the most closely related populations (FST=0.016. These results are confirmed by Nei’s genetic distances with the highest value observed between the Posavina horse and the Murinsulaner (0.082 and the lowest between the Posavina horse and the Croatian Coldblood (0.044. An assignment test correctly assigned 82% of individuals to the correct breed. Strategies for preserving the original native genes in the Croatian native horse breeds should be considered in order to prevent these breeds from becoming extinct and include them in the future breeding programmes.

On the System of Place Name Signs in Estonian Sign Language

Directory of Open Access Journals (Sweden)

Liina Paales

2011-05-01

Full Text Available A place name sign is a linguistic-cultural marker that includes both memory and landscape. The author regards toponymic signs in Estonian Sign Language as representations of images held by the Estonian Deaf community: they reflect the geographical place, the period, the relationships of the Deaf community with hearing community, and the common and distinguishing features of the two cultures perceived by community's members. Name signs represent an element of signlore, which includes various types of creative linguistic play. There are stories hidden behind the place name signs that reveal the etymological origin of place name signs and reflect the community's memory. The purpose of this article is twofold. Firstly, it aims to introduce Estonian place name signs as Deaf signlore forms, analyse their structure and specify the main formation methods. Secondly, it interprets place-denoting signs in the light of understanding the foundations of Estonian Sign Language, Estonian Deaf education and education history, the traditions of local Deaf communities, and also of the cultural and local traditions of the dominant hearing communities. Both perspectives - linguistic and folkloristic - are represented in the current article.

Flue gas emissions from pulverized oil shale fired boilers of Estonian and Baltic power plants have been studied. The concentrations of NO x , CO, C x H y , HCI, Hf and polycyclic aromatic hydrocarbons in flue gases have been found to be relatively low and acceptable according to German emission limits, for instance. Desulphurization degree of flue gases by SO 2 absorption with ash has been found to vary defending on boiler type and operation conditions. In spite of significant sulphur capture (average values for different boilers in the range between 68 and 77 % of the initial sulphur content of the fuel), SO 2 concentrations in flue gases remain still very high (up to 2600 mg/m 3 , 10% O 2 ). Very high concentrations of particles, especially at Estonian Power Plant (up o 6250 mg/m 3 , 10 % 0 2 ) have been detected. Heavy metal emissions were too high by the reason of particle control insufficiency as well. Yearly emission estimates of this study support the former Estonian ones within the range of 10-15 %.

Full Text Available An experiment of crossing a heavier-weight semi-breed horse (Holstein with mares of Croatian Posavian type draft horse resulted in possibility of such further crossing. Attained product meets today’s market requirements: firstly as an export-meat category that meets Italian market requirements, since other markets are not well known, secondly, it can be used as a sport-tourist-recreation horse. It must be pointed out that all produced hybrids did not meet the needs of these two basic criteria. In spite of being potential slaughtery head with good utilization, each produced head can be, according to its exterial properties, used as a sporttourist animal that showed certain usable values and results proven by the experiment. The hybrids showed some hereditory draft horse properties shown on enclosed photos. In addition, exterier measures show that former knowledge on hybrids can respond the question of a horse raising on non-utilized pastures which they got used to very well. Thus these horses are able to be estimated by their body development just as our native draft Posavian type horse including possibility of using them as a sport-tourist-recreation horse.

Estonian Language of Technology as a Factor Supporting the Evolution of Engineering Thinking

Directory of Open Access Journals (Sweden)

Mägi, Vahur

2013-03-01

Full Text Available Casual mention of teaching technology subjects in Estonian schools dates back several centuries. Navigation and construction were amongthe earliest professional skills that were taught. As both of them required mathematical thinking skills, teaching the subjects was usually accompanied by explaining the principles of mathematics. The first technology book in Estonian was published about two centuries ago and it dealed with geodesy. The earliest Estonian glossaries of technological terminology were published in the fields of physics and chemistry. The rise of Estonian as a language of higher education and science in the country came about in the 1920s and 1930s. Faculty members of the Tallinn School of Technology then published the first textbooks composed in the Estonian language for students of technology. The Estonian Society for Technology and the Estonian Association of Engineers became seriously involved in linguistic activities. Together with the Vocational Teachers’ Assembly of Tartu they published an illustrated technology glossary for machinery and tools terms. It was followed by a glossary of construction and building terms, compiled under the lead of the University of Technology. In addition, journals of technology introducedinnovations in the lexicon of technology to the general public. The postwar period in the development of the lexicon of technical terms was of little significance at first. A surge in language creativity could be detected in the 1960s, when terminology became a target of constantly growing attention to the development of technology lexicon. Series of technology glossaries were published. This tendency has continued to this day.

Full Text Available A total of 90 mares and horses were subjected to blood sampling for determining the effect of management (farm, reproductive condition, sex, age, breed and month of the year during breeding on circulating levels of cortisol and sex hormones. Blood samples were collected from December to the following June from four farms. Blood sera underwent testosterone, estradiol, progesterone and cortisol assaying using ELISA kits. Cortisol levels were significantly low in lactating mares during their foal heat but significantly high levels were recorded in both repeat breeder mares and horses used for racing. High and significant testosterone and estradiol levels were recorded in both stallions used for breeding especially after semen collection and early pregnant mares. Similar testosterone levels were recorded in both early pregnant mares and racing horses but high levels were recorded in stallions. Estradiol was high in both early pregnant and mares with endometritis but the highest levels were observed in stallions. Horses held in private farms had high cortisol levels compared to those of governmental farms. In contrast to mares, horses had low cortisol and high estradiol levels. Cortisol levels were high from April to June (Spring and early summer compared to its levels from December to March (Winter. Arab horses had low cortisol compared to native and imported foreign breeds. In conclusion, environmental condition, exercise, breed, management and the purpose of raising horses all are affecting its cortisol levels.

Noor eesti teater ja Noor-Eesti. Young Estonian Theatre and Young Estonia

Katri Aaslav-Tepandi

2012-04-01

Full Text Available This article begins by examining points of intersection between two professional theatres, ”Estonia” and ”Vanemuine” (both established in 1906, their young directors – Karl Menning, Paul Pinna, Theodor Altermann, and Karl Jungholz, and the literary movement Young Estonia. Subsequently, we will consider Young Estonia’s theatrical ideals and the influence of these ideas on later Estonian theatrical life. Since not much information has survived regarding direct personal contacts between ”movers and shakers” in the theatre world and Young Estonians, the main focus here shall be on indirect creative connections and influences. One such context is education: like the Young Estonians, theatre activists of the younger generation aspired to place themselves on the larger map of European culture. Thus, their artistic beliefs and goals shall be examined in relation to those of Young Estonians’ quest for modern culture. Pinna, Altermann, Menning, Jungholz, and others went on study tours to Germany and France, where they were energized and inspired by innovative German and Russian theatres, by naturalistic staging, and by psychological realism, both in acting and in performance style. Among their models were A. Antoine’s Théâtre- Libre in Paris, K. Stanislavski’s Art Theatre in Moscow, O. Brahm’s Lessing-Theater, and M. Reinhardt’s Deutsches Theater in Berlin. These models were likewise known to the Young Estonians, but if theatre activists oriented themselves more fundamentally to German naturalist and realist dramatic art, Young Estonians were more taken with ”theatrical theatre” with its symbolist and impressionist influences. The Young Estonians attended performances at both theatres, ”Vanemuine” and ”Estonia”, and wrote numerous theatre reviews. Yet in the Young Estonia albums (yearbooks and in the magazine Young Estonia, theatre topics have a relatively modest representation. Young Estonians did not have direct

We constructed a 400K WG tiling oligoarray for the horse and applied it for the discovery of copy number variations (CNVs) in 38 normal horses of 16 diverse breeds, and the Przewalski horse. Probes on the array represented 18,763 autosomal and X-linked genes, and intergenic, sub-telomeric and chrY sequences. We identified 258 CNV regions (CNVRs) across all autosomes, chrX and chrUn, but not in chrY. CNVs comprised 1.3% of the horse genome with chr12 being most enriched. American Miniature horses had the highest and American Quarter Horses the lowest number of CNVs in relation to Thoroughbred reference. The Przewalski horse was similar to native ponies and draft breeds. The majority of CNVRs involved genes, while 20% were located in intergenic regions. Similar to previous studies in horses and other mammals, molecular functions of CNV-associated genes were predominantly in sensory perception, immunity and reproduction. The findings were integrated with previous studies to generate a composite genome-wide dataset of 1476 CNVRs. Of these, 301 CNVRs were shared between studies, while 1174 were novel and require further validation. Integrated data revealed that to date, 41 out of over 400 breeds of the domestic horse have been analyzed for CNVs, of which 11 new breeds were added in this study. Finally, the composite CNV dataset was applied in a pilot study for the discovery of CNVs in 6 horses with XY disorders of sexual development. A homozygous deletion involving AKR1C gene cluster in chr29 in two affected horses was considered possibly causative because of the known role of AKR1C genes in testicular androgen synthesis and sexual development. While the findings improve and integrate the knowledge of CNVs in horses, they also show that for effective discovery of variants of biomedical importance, more breeds and individuals need to be analyzed using comparable methodological approaches.

2017-12-01

Full Text Available Since its independence in 1991 Estonia has successfully overpassed the challenges of the transition period being in the present of one the most technologically developed nations of Europe. The present research is intended to evaluate the relationship between Estonian pro-market regulation, entrepreneurship and innovation. In order to reach relevant conclusions in this regard there have been used both qualitative and quantitative methods of analysis. In such a way, it could be comprehensively reviewed the process of Estonian economic development from a relatively underdeveloped USSR republic to an advanced innovation driven economy. The results show that pro-market governmental regulation has favourably influenced Estonian entrepreneurship, while it fostered country’s innovation capacities. It has been concluded that the economic “miracle” of Estonia has been at a great extent determined by proper government regulation oriented towards economic liberalisation.

Efficiency of Estonian grain farms in 2000 2004

2008-12-01

Full Text Available The aim of this study is to analyse the efficiency of Estonian grain farms after Estonia’s transition to a market economy and during the accession period to the European Union (EU. The non-parametric method Data Envelopment Analysis (DEA was used to estimate the total technical, pure technical and scale efficiency of Estonian grain farms in 2000–2004. Mean total technical efficiency varied from 0.70 to 0.78. Of the grain farms 62% are operating under increasing returns to scale. Solely based on the DEA model it is not possible to determine optimum farm scale and the range of Estonian farm sizes operating efficiently is extensive. The most pure technically efficient farms were the smallest and the largest but the productivity of small farms is low compared to larger farms because of their small scale. Therefore, they are the least competitive. Since pre-accession period to the EU, large input slacks of capital have replaced the former excessive use of labour and land. This raises the question about the effects on efficiency of the EU’s investment support schemes in new member states.;

The Category of Time in Fairy Tales: Searching for Folk Calendar Time in the Estonian Fairy Tale Corpus

2011-03-01

Full Text Available The article examines how folk calendar holidays are represented in Estonian fairy tales. It introduces some views presented in folklore studies about the concept of time in fairy tales and finds parallels with them in the Estonian context. The analysis relies on the digital corpus of Estonian fairy tales (5400 variants, created from the texts found in the Estonian Folklore Archives by the Fairy Tale Project of the Department of Estonian and Comparative Folklore, University of Tartu. Folk calendar holidays occur in Estonian fairy tales relatively seldom; most often these are holidays that occupy a significant place in the Estonian folk calendar (Christmas, St. John’s Day, Easter, St. George’s Day. Calendar holidays are notably mentioned more often in tale types which remain on the borderline between the fairy tale and the legend or the fairy tale and the religious tale. In Estonian fairy tales, calendar holidays are used on three levels of meaning: (1 the holiday is organically associated with the tale type; it has an essential role in the plot of the tale; (2 to a certain extent, the holiday could be replaced by another holiday having an analogous meaning; (3 the holiday forms an unimportant or occasional addition to the tale.

Revisiting the Estonian Cyber Attacks: Digital Threats and Multinational Responses

Directory of Open Access Journals (Sweden)

Stephen Herzog

2011-01-01

Full Text Available In April 2007, the Estonian Government moved a memorial commemorating the Soviet liberation of the country from the Nazis to a less prominent and visible location in Tallinn. This decision triggered rioting among Russian-speaking minorities and cyber terrorism targeting Estonia's critical economic and political infrastructure. Drawing upon the Estonian cyber attacks, this article argues that globalization and the Internet have enabled transnational groups—such as the Russian diaspora—to avenge their grievances by threatening the sovereignty of nation-states in cyberspace. Sophisticated and virtually untraceable political "hacktivists" may now possess the ability to disrupt or destroy government operations, banking transactions, city power grids, and even military weapon systems. Fortunately, western countries banded together to effectively combat the Estonian cyber attacks and minimize their effects. However, this article concludes that in the age of globalization, interdependence, and digital interconnectedness, nation-states must engage in increased cooperative cyber-defense activities to counter and prevent devastating Internet attacks and their implications.

Maternal phylogenetic relationships and genetic variation among Arabian horse populations using whole mitochondrial DNA D-loop sequencing.

Science.gov (United States)

Khanshour, Anas M; Cothran, Ernest Gus

2013-09-13

Maternal inheritance is an essential point in Arabian horse population genetics and strains classification. The mitochondrial DNA (mtDNA) sequencing is a highly informative tool to investigate maternal lineages. We sequenced the whole mtDNA D-loop of 251 Arabian horses to study the genetic diversity and phylogenetic relationships of Arabian populations and to examine the traditional strain classification system that depends on maternal family lines using native Arabian horses from the Middle East. The variability in the upstream region of the D-loop revealed additional differences among the haplotypes that had identical sequences in the hypervariable region 1 (HVR1). While the American-Arabians showed relatively low diversity, the Syrian population was the most variable and contained a very rare and old haplogroup. The Middle Eastern horses had major genetic contributions to the Western horses and there was no clear pattern of differentiation among all tested populations. Our results also showed that several individuals from different strains shared a single haplotype, and individuals from a single strain were represented in clearly separated haplogroups. The whole mtDNA D-loop sequence was more powerful for analysis of the maternal genetic diversity in the Arabian horses than using just the HVR1. Native populations from the Middle East, such as Syrians, could be suggested as a hot spot of genetic diversity and may help in understanding the evolution history of the Arabian horse breed. Most importantly, there was no evidence that the Arabian horse breed has clear subdivisions depending on the traditional maternal based strain classification system.

Merili Metsvahi

2013-12-01

Full Text Available The article analyses tale type The Woman as Wolf, which is one of the most popular folk tales in the Estonian Folklore Archives and is represented there both in the form of a fairy tale and in the form of a legend. The vast majority of the versions of The Woman as Wolf were written down in the first part of the 20th century within Estonia and where recorded from Estonians. The article introduces the content of the tale, the origin of the first records from the early 19th century, and the dissemination area of the tale, which remains outside Western Europe: apart from the Estonian versions there are Sami, Karelian, Vepsian, Livonian, Latvian, Lithuanian, Russian, Ukrainian and Belarusian versions. While in almost all the Estonian versions the main protagonist is transformed into a wolf, in most of the versions written down in other areas and ethnic groups, another animal or bird replaces the wolf. The author is of the opinion that the Finnic area is central to the distribution of the folk tale The Woman as Wolf. The animal the woman is transformed into in the plot would not have been a wolf in earlier times. The article provides an explanation why the wolf is predominant in Estonian written sources. For that purpose the ways in which the wolf and werewolf were perceived in earlier Estonian folk belief are introduced. At the end of the article interpretation of the folk tale is provided. The author states that the plot and some of the motifs found in this folk tale reflect the difficulties women had in submitting to the norms and values of patriarchal order within their society.

Yakutia, Sakha Republic, in the Siberian Far East, represents one of the coldest places on Earth, with winter record temperatures dropping below -70 °C. Nevertheless, Yakutian horses survive all year round in the open air due to striking phenotypic adaptations, including compact body conformations, extremely hairy winter coats, and acute seasonal differences in metabolic activities. The evolutionary origins of Yakutian horses and the genetic basis of their adaptations remain, however, contentious. Here, we present the complete genomes of nine present-day Yakutian horses and two ancient specimens dating from the early 19th century and ∼5,200 y ago. By comparing these genomes with the genomes of two Late Pleistocene, 27 domesticated, and three wild Przewalski's horses, we find that contemporary Yakutian horses do not descend from the native horses that populated the region until the mid-Holocene, but were most likely introduced following the migration of the Yakut people a few centuries ago. Thus, they represent one of the fastest cases of adaptation to the extreme temperatures of the Arctic. We find cis-regulatory mutations to have contributed more than nonsynonymous changes to their adaptation, likely due to the comparatively limited standing variation within gene bodies at the time the population was founded. Genes involved in hair development, body size, and metabolic and hormone signaling pathways represent an essential part of the Yakutian horse adaptive genetic toolkit. Finally, we find evidence for convergent evolution with native human populations and woolly mammoths, suggesting that only a few evolutionary strategies are compatible with survival in extremely cold environments.

Critical Success Factors and information needs in Estonian industry

Full Text Available The article reports the results of the study on the critical success factors and related information needs in Estonian industry conducted in 1999. Data were collected by interviews with 27 managers and engineers from 16 manufacturing companies in various industries. Most of the critical success factors taken up were related to marketing, information management, quality management, product development and technological innovations. The information needs of managers and engineers were related to competitors, customers, markets, technology, regulations, etc. Some identified CSFs expressed also priorities for development by Estonian economic authorities: to support the implementation of new technologies and introduction of quality management methods. The finding that information management was perceived as a very critical area supports the result of the recent Finnish study on CSFs.

Full Text Available The article deals with the development in Russian-Estonian relations during the crises of 2007 and 2014, taking into consideration the balance between political and economic factors in the decision-making by Estonian government. A number of special aspects, trends and problems in trade and investment ties are detected. The aim of the study is to uncover key motivation behind the actions of both Russia and Estonia, to identify the drivers for economic and political development in the region, and to work out recommendations to adjust them. The questions put forward by the authors of this article could not be more topical at the time, when Russian economic situation is obviously getting worse and capital flight (to the neighboring EU Member States is likely to increase. The method of the study is comparative analysis of the impact on economic ties made by Russian-Estonian crisis of 2007 and the current international tension around Ukraine. The regional fossil fuel market and the possibilities of Gazprom involvement in its development are also analyzed. It is concluded that political motives are still important for Estonian decisionmaking, though they are balanced out by measures of business support (despite some of these measures being taken by the EU bodies. The role of political factor for the Russian side is increasing. It is acknowledged that there is a growing number of missed economic opportunities in the Russian Northwest.

Overview of the Estonian Biofuels Association activities

Due to global warming and environment pollution because of widespread use of fossil fuels there are already tendencies to stabilize and decrease the consumption of these energy resources and take into use more renewable energy resources. Estonian Biofuels Association (EBA) is a non-profit association, which was founded on 8. of May 1998 in Tallinn. The EBA is an independent and voluntary alliance of its members. Fields of activity of the EBA are by biofuels research, developing and evaluation to engage environmental, biofuels and energy saving. EBA members are: energy consultants, scientists, as well as fuel suppliers, DH-companies, technology suppliers, energy service companies etc. The members of EBA are involved in different projects in Estonia, where biomass are produced and used for heating, where wood, waste, peat, rape oil and biogas resources are examined and put into use, and also projects which deal with energy saving and environment friendly equipment production for using biofuels. During our short experience we have noticed that people in Estonia have become more aware of biomass and their use, so the development of environment friendly and sustainable energetics will continue in Estonia. Available biofuels in Estonia could compete with fossil fuels if burnt rationally with high technology equipment. EBA members are convinced that biomass have perspective and that they could play an important role in improving Estonian economic and environmental situation. Modem biomass combustion devices are taken into use more the faster general wealth increases and EBA can raise people's awareness of bio fuel subject through special, courses and media. We want Estonian energy policy to develop towards widespread use of renewable energy resources, which would save energy and environment improve nation's foreign trade balance and create jobs mainly in rural areas

2017-09-01

Full Text Available This article attempts to explain the relationships between journalists, politics and the state from the perspective of collective autonomy, that of the professional organization of journalists. The case of Estonian Journalists’ Union demonstrates the complexity and historical contingency of professional autonomy of journalism. The development of the Estonian journalists’ organization occurred as a sequence of transformations from the Estonian Journalists’ Association to the Estonian Journalists’ Union to the Soviet type journalists’ union, and lastly to an independent trade union. This sequence was disrupted by several fatal breakdowns that changed not only the character of the association, but also professional values, the whole occupational ideology and the conditions of the existence of journalism as a profession in Estonia.

The Estonian study of Chernobyl cleanup workers. I. Introduction

1999-01-01

The most comprehensive epidemiological project ever performed in Estonia - The Estonian Study of Chernobyl Cleanup Workers - was the joint effort of researchers from Estonia, Finland and USA. Until September 1999, the results of this study were published in English only. To familiarize the readership of 'Eesti Arst' with the major study findings, the abridged versions of four original papers from 'Radiation Research' are presented in the current issue of the journal. For the Estonian epidemiologists, the work under this project that consists of eight sub projects was a real challenge. In the course of the study, skills were developed in writing a study protocol, preparing a questionnaire, progress reporting, documenting the structure of databases, record linkage, and problem solving. It was an exciting experience to work with top scientists like William Bigbee, John Boice, Timo Hakulinen, Ronald Jensen and Gayle Littlefield. (author)

Sustainable development outlooks of the Estonian energy sector for convergence with the European Union countries

The article presents an overview of a research conducted in the Estonian Inst. of Economics and the Estonian Energy Research Inst. with the objectives to: analyse the dynamics of the main Estonian energy use indicators over the last 8-10 years with the background of general macroeconomics developments; compare these indicators with the respective energy indicators in the European Union Member States and Candidate Countries; evaluate Estonia's potential to catch up by the energy use efficiency (GDP energy intensity) of the average level of EU countries, modelling our possible development scenarios of GDP and TPES. The research results indicates several positive development tendencies (e.g. reduction of TPES and CO 2 emissions with the background of economic growth) in the Estonian energy sector, as well as convergence with the EU countries in terms of GDP energy intensity. Unfortunately, the model analysis results demonstrate that it takes a lot of time for Estonia to reach the current EU level - even under the most favourable GDP and TPES development conditions, 25-30 years. The primary reason is the very low level of our GDP per capita compared to the EU countries. (author)

Full Text Available The article concentrates on Estonian novels depicting Soviet prison camps in the 1940s and 1950s. The goal is to map themes, motifs and characteristics in such novels, concentrating on various taboos and rules in the prison camp environment. For a long time the Soviet prison camp theme was not publicly discussed in Estonia due to political reasons. Texts dealing with prison camps could appear in print only outside the Soviet Union; the way Estonians saw these historical events and hellish experiences were depicted mostly in exile novels. Most notable are the novels by Arved Viirlaid (b. 1922, e.g., Kes tappis Eerik Hormi? (Who Killed Eerik Horm? (1974, Surnud ei loe (The Dead do not Read (1975, Vaim ja ahelad (Mind and Chains (1961. Estonian prison camp novels can be seen as “the literature of testimony”, to use the term by Leona Toker. Dramatic historical events are written down to record the events and to show the inhumane nature of Soviet society. These records of the dramatic past follow certain patterns and create certain self- and hetero-images. A prison camp is a closed territory within a closed territory; prison camps can be seen as small models of Soviet society. Prison camp novels give a detailed view of the environment of the prison camp, its inhabitants and activities. Two central aspects are labour and food; the life of the prisoner whirls around these. The most important thing is to survive, which often leads to moral decline, e.g., stealing, cheating. However, there are lines Estonians do not cross, e.g., cannibalism or homosexual relationships with superiors. Estonians are always depicted as political prisoners (not common criminals and heterosexuals, while Russians are portrayed mainly as criminals and often also as homosexuals. Another important component of the image of the Estonians is their enterprising spirit and ability to manage even under very difficult conditions. Therefore, several oppositions can be identified, e

Estonian wind climate

Kull, Ain

1999-01-01

Estonia is situated on the eastern coast of the Baltic Sea. This is a region with intensive cyclonic activity and therefore with a relatively high mean wind speed. Atmospheric circulation and its seasonal variation determine the general character of the Estonian wind regime over the Atlantic Ocean and Eurasia. However, the Baltic sea itself is a very important factor affecting wind climate, it has an especially strong influence on the wind regime in costal areas. The mean energy density (W/m 2 ) is a wind energy characteristic that is proportional to the third power of wind speed and describes energy available in a flow of air through a unit area. The mean energy density is a characteristic which has practical importance in regional assessment of snowdrift, storm damage and wind energy

Landscape-Scale Factors Affecting Feral Horse Habitat Use During Summer Within The Rocky Mountain Foothills

Science.gov (United States)

Girard, Tisa L.; Bork, Edward W.; Neilsen, Scott E.; Alexander, Mike J.

2013-02-01

Public lands occupied by feral horses in North America are frequently managed for multiple uses with land use conflict occurring among feral horses, livestock, wildlife, and native grassland conservation. The factors affecting habitat use by horses is critical to understand where conflict may be greatest. We related horse presence and abundance to landscape attributes in a GIS to examine habitat preferences using 98 field plots sampled within a portion of the Rocky Mountain Forest Reserve of SW Alberta, Canada. Horse abundance was greatest in grassland and cut block habitats, and lowest in conifer and mixedwood forest. Resource selection probability functions and count models of faecal abundance indicated that horses preferred areas closer to water, with reduced topographic ruggedness, situated farther from forests, and located farther away from primary roads and trails frequented by recreationalists, but closer to small linear features (i.e. cut lines) that may be used as beneficial travel corridors. Horse presence and abundance were closely related to cattle presence during summer, suggesting that both herbivores utilise the same habitats. Estimates of forage biomass removal (44 %) by mid-July were near maximum acceptable levels. In contrast to horse-cattle associations, horses were negatively associated with wild ungulate abundance, although the mechanism behind this remains unclear and warrants further investigation. Our results indicate that feral horses in SW Alberta exhibit complex habitat selection patterns during spring and summer, including overlap in use with livestock. This finding highlights the need to assess and manage herbivore populations consistent with rangeland carrying capacity and the maintenance of range health.

The report describes the development and summarizes the results of the project Cancer incidence and thyroid disease among Estonian Chernobyl clean-up workers. One of the goals of the report is to give research protocols and questionnaires for researchers involved in other studies. Eight previously published articles are also included summarizing the results. The development of the collaboration work of the project is described in the introduction of the report. Epidemiological methods are described in an article complemented by the protocol and English version of the questionnaire administered to all cleanup workers, as well as the data collection form of the thyroid study. The results from biological biodosimetry using both glycophorin A and FISH methods have shown that the radiation doses received by the Chernobyl cleanup workers were relatively low. Thyroid nodularity was not associated with any radiation exposure characteristic in the thyroid screening study. Estonian Chernobyl cleanup workers were followed up for cancer incidence through the Estonian Cancer Registry. No cases of leukemia or thyroid cancer were observed by the end of 1993. It is too early to observe possible effect on other types of cancer. However, mortality from suicides was increased compared with general population. Further follow-up and the extension to other Baltic countries in the future will undoubtedly strengthen the study. There are also plans for future projects covering areas from psychosocial factors to radiation biology

With or without articles? A comparison of article-like determiners in Estonian and Finnish

Full Text Available In this paper, we compare the use and functions of definite and indefinite article-like determiners in Estonian and Finnish. Our main aim is to explore whether the factors that explain the choice of particular determiner forms are similar in Estonian and Finnish. We use a picture-sequence based elicitation experiment to collect spoken narratives from adult native speakers of Estonian and Finnish, and apply non-parametric tree and forest models to analyze the data. Our findings indicate that number of mention and animacy are important predictor variables in both languages, but their exact effect is divergent. We also find that in Finnish, case of the determiner NP proves to be an important factor, while in Estonian, syntactic role of the NP explains some aspects of determiner form choice. Nevertheless, the overall usage frequency of determiners is modest in the Estonian and Finnish data, and the process of grammaticalizing articles is only in initial stages in both languages. *** Artikliga, artiklita?

Full Text Available The paper seeks to analyse family businesses in rural areas, family business strategies and re-registration of sole proprietors with the Centre of Registers and Information Systems (hereinafter Commercial Register in 2009, and to provide an overview of entrepreneurship policies targeted at Estonian rural businesses. Layoffs have increased the number of unemployed; some of those who have lost employment opt for social assistance benefits, but some others decide to become entrepreneurs. Many enterprising people in Estonia have set up a family enterprise, mainly in the sphere of services, agriculture and tourism. The Estonian entrepreneurship policy supports enterprising people and approves of entrepreneurship as a promoter of national economic development. One of the most positive qualities of family enterprises is their short decision-making chain, which ensures rapid implementation of the strategy.

Utilisation of Estonian energy wood resources

Energy Technology Data Exchange (ETDEWEB)

Muiste, P.; Tullus, H.; Uri, V. [Estonian Agricultural University, Tartu (Estonia)

1996-12-31

In the end of the Soviet period in the 1980s, a long-term energy programme for Estonia was worked out. The energy system was planned to be based on nuclear power and the share of domestic alternative sources of energy was low. The situation has greatly changed after the re-establishment of the Estonian independence, and now wood and peat fuels play an important role in the energy system. Energy consumption in Estonia decreased during the period 1970-1993, but this process has less influenced the consumption of domestic renewable fuels - peat and wood. It means that the share of these fuels has grown. The investment on substitution of imported fossil fuels and on conversion of boiler plants from fossil fuels to domestic fuels has reached the level of USD 100 million. The perspectives of the wood energy depend mainly on two factors; the resources and the price of wood energy compared with other fuels. The situation in wood market influences both the possible quantities and the price. It is typical that the quickly growing cost of labour power in Estonia is greatly affecting the price of energy wood. Though the price level of fuel peat and wood chips is lower than the world market price today, the conditions for using biofuels could be more favourable, if higher environmental fees were introduced. In conjunction with increasing utilisation of biofuels it is important to evaluate possible emissions or removal of greenhouse gases from Estonian forests 3 refs.

Full Text Available Measurements of 7 body measures and 6 indices of body conformation on 34 breeding individuals of Moravian warm-blooded horse and 19 of Sarvar horse (Leutstettener were used to analyse the effect of country of origin (Czech Republik, Germany, sire lines or breed (Furioso, Przedswit, English thoroughbred, Sarvar, Others and age (4 classes. All horses were measured by one person. Measures and indexes were analysed by GLM procedure. Significant differences were found between both Czech and German population only in index of body frame. Sarvar horses are longer to their height than Moravian warm-blooded horses. The shorter body frame have the horses by English thoroughbred, the longer by Furioso. The younger horses are higher than the older. According to results of Linear Description of Body Conformation we found out, that population of Sarvar horse is more balanced than population of Moravian warm-blooded horse.

This study examined the smoking habits and attitudes towards smoking among Estonian physicians. Cross-sectional data for 2668 physicians were gathered by a self-administered postal survey. The current smoking prevalence was 24.9% for male physicians and 10.8% for female physicians. The percentages of ex-smokers were 32.9 and 16.8%, respectively. Smoking prevalence among physicians was below the levels reported for the highest educational bracket of the total population in Estonia. Non-smoking physicians had more unfavourable views towards smoking than those who smoked. The majority of physicians were aware of the association between smoking and various diseases, with significant differences between smokers and non-smokers. Non-smoking physicians were more active in asking patients about smoking habits than those who smoked. Most Estonian physicians, especially those who smoked, failed to perceive themselves as positive role models. This study found a lower prevalence of smoking among physicians compared with the general population, and demonstrated the impact of personal smoking on physicians' attitudes towards smoking. The results provide an important challenge to medical education in Estonia.

Welfare of Aged Horses

Directory of Open Access Journals (Sweden)

Catherine McGowan

2011-10-01

Full Text Available Horses form a unique and special part of their owners’ lives and aged horses are no exception. This review considers the health and management of aged horses, including the role of the owner and their perceptions of aged horses, potential threats or risks to their welfare and finally, factors affecting quality of life and euthanasia of aged horses. Owners of aged horses are concerned about the health, welfare and quality of life of their aged animals. Yet surveys of management and preventive healthcare reflect that there may be some limitations to what owners are actually achieving in practice. They show declining management as horses age, particularly for the retired horse and insufficient appropriate preventive healthcare via veterinary surgeons. The veterinary surgeon plays an essential and influential role in preventive healthcare, management of diseases and disorders and ultimately in the decision making process for euthanasia of aged horses at the end of their lives. The value of aged horses should not be underestimated by veterinarians and others working with them and the continuing care of aged horses should be regarded with the same importance as the care of younger horses with more obvious monetary value.

Soil organic carbon (SOC) determines ecosystem functions, influencing soil fertility, soil physical, chemical and biological properties and crop productivity. Therefore the spatial pattern of SOC stocks and its appropriate management is important at various scales. Due to climate change and the contribution of carbon store in the soils, the national estimates of soil carbon stocks should be determined. Estonian soils have been well studied and mapped at a scale 1:10,000. Previous studies have estimated SOC stocks based on combinations of large groups of Estonian soils and the mean values of the soil profile database, but were not embedded into the geo-referenced databases. These studies have estimated SOC stocks of Estonian arable soils 122.3 Tg. Despite of available soil maps and databases, this information is still very poorly used for spatial soil modelling. The aim of current study is to assess and model spatial pattern of SOC stocks of arable soils on a pilot area Tartu County (area 3089 sq km). Estonian digital soil map and soil monitoring databases are providing a good opportunity to assess SOC stocks at various scales. The qualitative nature of the initial data from a soil map prohibits any straightforward use in modelling. Thus we have used several databases to construct models and linkages between soil properties that can be integrated into soil map. First step was to reorganize the soil map database (44,046 mapping units) so it can be used as an input to modelling. Arable areas were distinguished by a field layer of Agricultural Registers and Information Board, which provides precise information of current land use as it is the basis of paying CAP subsidies. The estimates of SOC content were found by using the arable land evaluation database of Tartu from the Estonian Land Board (comprising 950 sq km and 31,226 fields), where each soil type was assessed separately and average SOC content grouped by texture was derived. SOC content of epipedon varies in

This study was intended to identify genes positively selected in Thoroughbred horses (THBs) that potentially contribute to their running performances. The genomes of THB and Jeju horses (JH, Korean native horse) were compared to identify genes positively selected in THB. We performed cross-population extended haplotype homozygosity (XP-EHH) and cross-population composite likelihood ratio test (XP-CLR) statistical methods for our analysis using whole genome resequencing data of 14 THB and 6 JH. We identified 98 (XP-EHH) and 200 (XP-CLR) genes that are under positive selection in THB. Gene enrichment analysis identified 72 BP terms. The genes and BP terms explained some of THB's characteristics such as immunity, energy metabolism and eye size and function related to running performances. GO terms that play key roles in several cell signaling mechanisms, which affected ocular size and visual functions were identified. GO term Eye photoreceptor cell differentiation is among the terms annotated presumed to affect eye size. Our analysis revealed some positively selected candidate genes in THB related to their racing performances. The genes detected are related to the immunity, ocular size and function, and energy metabolism.

To compare smoking behaviour, attitudes and opinions towards smoking and smoking cessation among Estonian and Finnish physicians. A cross-sectional postal survey using a self-administered questionnaire was carried out among 2,480 Estonian and 2,075 Finnish physicians. Daily smoking prevalence was higher among Estonian physicians than among their Finnish counterparts in both male (18.6% and 6.7%) and female (6.6% and 3.6%). Compared to Estonia, physicians in Finland more often agreed that smoking is very harmful to their health, that trying to convince people to stop smoking is their responsibility and that smoking prevention should be part of the normal and special training of health professionals. In both countries, non-smoking physicians held more unfavourable attitudes towards smoking than those who were smoking. Physicians' own smoking patterns and quitting behaviour are important because physicians serve as models for their patients and play a key role in the reinforcement of smoke-free health facilities. These results remain a challenge to medical educators, especially in Estonia. Estonia needs to improve medical education in terms of motivating physicians to ask about the smoking patterns of their patients and of training medical students and resident physicians to counsel their patients to stop smoking.

Despite their ability to interbreed and produce fertile offspring, there is continued disagreement about the genetic relationship of the domestic horse (Equus caballus) to its endangered wild relative, Przewalski's horse (Equus przewalskii). Analyses have differed as to whether or not Przewalski's horse is placed phylogenetically as a separate sister group to domestic horses. Because Przewalski's horse and domestic horse are so closely related, genetic data can also be used to infer domestication-specific differences between the two. To investigate the genetic relationship of Przewalski's horse to the domestic horse and to address whether evolution of the domestic horse is driven by males or females, five homologous introns (a total of approximately 3 kb) were sequenced on the X and Y chromosomes in two Przewalski's horses and three breeds of domestic horses: Arabian horse, Mongolian domestic horse, and Dartmoor pony. Five autosomal introns (a total of approximately 6 kb) were sequenced for these horses as well. The sequences of sex chromosomal and autosomal introns were used to determine nucleotide diversity and the forces driving evolution in these species. As a result, X chromosomal and autosomal data do not place Przewalski's horses in a separate clade within phylogenetic trees for horses, suggesting a close relationship between domestic and Przewalski's horses. It was also found that there was a lack of nucleotide diversity on the Y chromosome and higher nucleotide diversity than expected on the X chromosome in domestic horses as compared with the Y chromosome and autosomes. This supports the hypothesis that very few male horses along with numerous female horses founded the various domestic horse breeds. Patterns of nucleotide diversity among different types of chromosomes were distinct for Przewalski's in contrast to domestic horses, supporting unique evolutionary histories of the two species.

Using micro-contexts to describe a writing process in Estonian as a second language across proficiency levels

Olga Pastuhhova

2015-04-01

Full Text Available This paper aims to describe the writing process of native Russian‑speaking students in Estonian as a second language. 34 participants were given the assignment of writing a text in the L2. The written texts were then rated as being at levels from A2 to C1 according to the Common European Framework of Reference for Languages (CEFR. The data were collected by computer keystroke logging and analysed based on the concept of a ‘micro-context’. Micro-contexts were analysed according to their frequency and duration and were compared across proficiency levels. The results show that writing in the L2 is not a smooth process. The longest transitions in micro-contexts reveal that the most cognitive effort is made between paragraphs and sentences and when deletions are involved. The growing number of consecutive deletions demonstrates that even with developing proficiency, the linear production text is subject to constant revision, correction and modification.

While the novel robotic hippotherapy system has gradually gained clinical application for therapeutic intervention on postural and locomotor control in individuals with neurological or musculoskeletal impairments, the system's validity and reliability for the robotic hippotherapy system has not been well established. The objective of the current study was to investigate the validity and test-retest reliability of the robotic hippotherapy system by comparing with real horse movements. The 3-axis accelerometer sensors attached on the robotic and real horse saddles were used to collect 3-dimensional acceleration data at a preferred walking velocity. Linear regression analysis showed an excellent correlation in the time-to-peak acceleration (TPA) (R(2)=0.997), but little correlation in X-axis acceleration between the real and robotic horses (R(2)=0.177), thus confirming consistent time control and a certain degree of variability between the robotic and real horse movements. The mean resultant accelerations for a real horse and robotic horse were 3.22 m/s(2) and 0.67 m/s(2), respectively, accounting for almost five times greater acceleration in the real horse than the robotic horse.

Little is known about the horse health management practices of Australian horse caregivers (owners). This article presents findings from a convenience sample of 505 horse owners who participated in an online survey. No large-scale welfare issues were identified, but there were some areas of potential concern, including owners who did not regularly deworm their horses (4%), a lack of strategic parasite control (3.1%), and a lack of regular dental care (11%). Several participants did not have their horse's hooves regularly shod or trimmed (2%), and 14% had an unqualified person maintain their horse's hooves. One in five owners (19%) did not vaccinate their horses against tetanus. The findings are discussed in relation to current Australian horse health guidelines and traditional sources of horse health information, together with recommendations for providing horse owners with relevant information in relevant forms.

Identity and Othering in Past and Present: Representations of the Soviet Era in Estonian Post-Soviet Textbooks

Directory of Open Access Journals (Sweden)

Katrin Kello

2018-02-01

Full Text Available This paper analyses representations of the ‘core Soviet era’ (1945-1985 in Estonian post-Soviet history textbooks (1989-2016. Attitudes towards the Soviet system have been a rich resource for identity building, and hence a powerful political tool across the whole of the post-Soviet block. Based on an analysis of sections about the Soviet era in Estonia in 21 textbooks, the paper takes a look at how textbooks reflect broader processes of social meaning making, identity building and othering after a profound social and political turn. In 1989 and during the early 1990s, perspectives and narratives in Estonian history textbooks were closely related to social memory and national politics, enacting a specific social representation of the Soviet era that dominated the Estonian-speaking public space during the 1990s. The Soviet era, Russia and local Russians became the main Others for Estonia and Estonians. Over time, public discourse has diversified. The national curriculum and textbooks, however, still maintain the canon that formed in 1990s and thus reflect earlier sentiments. Apart from the increasing salience of Soviet-era daily life in more recent textbooks, the thematic choices and emphases have changed little since the 1990s. Therefore, even if the style of writing has ‘cooled down’, issues of identity preservation, resistance and accommodation, together with a saliently negative representation of wrongdoings by the Soviet system, still prevail. On the one hand, this testifies to the resilience of an established tradition in the textbook genre in general. On the other hand, it reflects the dominance of an ethnocentric tradition in Estonian history textbook writing. The paper discusses the implications of these findings for interethnic relations in Estonia.

Although horses and donkeys belong to the same genus, their genetic characteristics probably result in specific proteomes and post-translational modifications (PTM) of proteins. Since PTM can alter protein properties, specific PTM may contribute to species-specific characteristics. Therefore, the aim of the present study was to analyse differences in serum protein profiles of horses and donkeys as well as mules, which combine the genetic backgrounds of both species. Additionally, changes in PTM of the protein transthyretin (TTR) were analysed. Serum protein profiles of each species (five animals per species) were determined using strong anion exchanger ProteinChips® (Bio-Rad, Munich, Germany) in combination with surface-enhanced laser desorption ionisation-time of flight MS. The PTM of TTR were analysed subsequently by immunoprecipitation in combination with matrix-assisted laser desorption ionisation-time of flight MS. Protein profiling revealed species-specific differences in the proteome, with some protein peaks present in all three species as well as protein peaks that were unique for donkeys and mules, horses and mules or for horses alone. The molecular weight of TTR of horses and donkeys differed by 30 Da, and both species revealed several modified forms of TTR besides the native form. The mass spectra of mules represented a merging of TTR spectra of horses and donkeys. In summary, the present study indicated that there are substantial differences in the proteome of horses and donkeys. Additionally, the results probably indicate that the proteome of mules reveal a higher similarity to donkeys than to horses.

Investigations of human outbreaks due to horse-meat consumption have implicated single cases of inadequate veterinary controls on horses imported from non-European Union countries. In particular, most cases of human infection have been attributed to horses imported from Eastern Europe, where pig trichinellosis is re-emerging and the main source of infection in horses.

Full Text Available Economic weights for milk carrier (water plus lactose, fat and protein yields, calving interval, age at first service, interval between the first service and conception of heifers and length of productive life of Estonian Holsteins were estimated under assumed milk production quota and for non-quota conditions. A bio-economic model of an integrated production system of a closed herd was used. Economic values of milk carrier yield and length of productive life differed between quota and non-quota conditions, but there were only minor differences between those marketing systems in economic values for functional traits. The standardised economic values of the most important traits varied in magnitude between18 to 81% of the economic value for milk yield. Discounting had a substantial impact on the economic value of length of productive life. When defining the breeding objective for Estonian Holstein, the interval between the first service and conception of heifers, and the length of productive life should be included in the breeding goal along with the traits with the highest economic value, milk, fat and protein yield. In the optimum breeding objective, relative weights of production vs. functional traits were 79 and 21%, respectively.;

Smoking surveys among physicians have proved useful in highlighting the importance of physicians as healthy life style exemplars and role models in tobacco control and smoking cessation. The aim of this study was to give an overview of smoking behaviour among Estonian physicians from 1982 to 2014. Three cross-sectional postal surveys using a self-administered questionnaire were carried out among all practising physicians in Estonia. The number of physicians participating in this study was 3786 in 1982, 2735 in 2002, and 2902 in 2014. Data analysis involved calculating the age-standardized prevalences of smoking, prevalences of smoking by age group and mean age of smoking initiation. A non-parametric test for trend was used to assess significant changes in smoking over time. Age-standardized prevalence of current smoking among men was 39.7% in 1982, 20.9% in 2002, and 14.3% in 2014 and among women 12.2%, 8.0%, and 5.2%, respectively (p smoking among men and women was in age groups under 35 (from 55.2% to 16.7% and from 16.7% to 2.8%, respectively) and 35-44 (from 47.1% to 8.3% and from 19.5% to 5.1%, respectively) (p smoking initiation decreased from 20.4 to 19.3 among men and from 24.5 to 20.4 among women over the study period. In 1982-2014, smoking prevalence among Estonian physicians declined substantially. This may influence the willingness of society to recognize the health consequences of smoking which could give a support to the decline of the smoking epidemic in the country. Differences between smoking among male and female physicians persisted over the study period, but mean age of smoking initiation decreased. A further decline in smoking among Estonian physicians should be encouraged by special efforts targeted at physicians.

Sak, Katrin; Jürisoo, Kadi; Raal, Ain

2014-07-01

Despite diagnostic and therapeutic advancements, the burden of cancer is still increasing worldwide. Toxicity of current chemotherapeutics to normal cells and their resistance to tumor cells highlights the urgent need for new drugs with minimal adverse side effects. The use of natural anticancer agents has entered into the area of cancer research and increased efforts are being made to isolate bioactive products from medicinal plants. To lead the search for plants with potential cytotoxic activity, ethnopharmacological knowledge can give a great contribution. Therefore, the attention of this review is devoted to the natural remedies traditionally used for the cancer treatment by Estonian people over a period of almost 150 years. Two massive databases, the first one stored in the Estonian Folklore Archives and the second one in the electronic database HERBA ( http://herba.folklore.ee/ ), containing altogether more than 30 000 ethnomedicinal texts were systematically reviewed to compile data about the Estonian folk traditional experiences on natural anticancer remedies. As a result, 44 different plants with potential anticancer properties were elicited, 5 of which [Angelica sylvestris L. (Apiaceae), Anthemis tinctoria L. (Asteraceae), Pinus sylvestris L. (Pinaceae), Sorbus aucuparia L. (Rosaceae), and Prunus padus L. (Rosaceae)] have not been previously described with respect to their tumoricidal activities in the scientific literature, suggesting thus the potential herbal materials for further investigations of natural anticancer compounds.

We present data from an observational cohort study on human immunodeficiency virus (HIV) prevention and control measures in prisons in Estonia to assess the potential for HIV transmission in this setting. HIV testing and retesting data from the Estonian prison health department were used to estimate HIV prevalence and incidence in prison. Since 2002, voluntary HIV counselling and testing has routinely been offered to all prisoners and has been part of the new prisoners health check. At the end of 2012, there were 3,289 prisoners in Estonia, including 170 women: 28.5% were drug users and 15.6% were infected with HIV. Of the HIV-positive inmates, 8.3% were newly diagnosed on prison entry. In 2012, 4,387 HIV tests (including retests) were performed in Estonian prisons. Among 1,756 initially HIV-negative prisoners who were in prison for more than one year and therefore tested for HIV twice within 12 months (at entry and annual testing), one new HIV infection was detected, an incidence of 0.067 per 100 person-years (95% confidence interval (CI): 0.025–5.572). This analysis indicates low risk of HIV transmission in Estonian prisons. Implementation of HIV management interventions could impact positively on the health of prisoners and the communities to which they return.

Full Text Available Horses have provided speed and mobility for Turkish people in steppes. Through war capability and skil ls of riding horse they were successful against resident communities in different geographies throughout history and when circumstances became difficult they migrated to convenient land riding horses. They benefited from horse's milk and meat as well as it s power and speed. In feast and festivals they compete with each other using horses, even if they played on horseback. This indicates that horses were how important for Turks in the political, civil, economic, social and cultural fields. Horse was located in the center of the lives of Turks throughout history. Such that, robbing a horse conneted was capital offence as well as rebellion, treason, murder, adultery according to the criminal law of the former Turks. Horse still has not lost its importance in t he present Turkish regions, especially Central Asian geography. Horse is so important for Turkmens that horse figure has taken place in the state coat of arms of Turkmenistan and the last sunday in April is celebrated as a feast in Turkmenistan. Ahal - Teke which is most exclusive horse breed of the word is brought up in Turkmenistan. Horse has also an important place in the vocabulary. In this work, it would be determine horse’s important in social and cultural life of Turkmens as following both language and non - language indicators.

To assess the refractive state of the equine eye utilizing retinoscopy. To compare the refractive state of Spanish Thoroughbred horses with the refractive state of Crossbred horses. The refractive state of 135 horses (264 eyes) was assessed utilizing streak retinoscopy. Two perpendicular meridians were examined in order to assess astigmatism at a working distance of approximately 67 cm. A group of 81 Spanish Thoroughbred horses was compared with a group of 54 Crossbred horses. Cyclopentolate ophthalmic solution was instilled in the eyes of a group of 18 horses to determine if accommodation has any influence on the assessment of the refractive state.   Mean ± SE refractive state of all horses examined was -0.17 ± 0.04 D. The mean refractive state of the Spanish Thoroughbred was -0.28 ± 0.06 D while that of the Crossbred was -0.01 ± 0.05 D. The refractive state of the Spanish Thoroughbred was found to be statistically different to that of the Crossbred. The most prevalent refractive state was emmetropia in all cases, followed by hyperopia for the Crossbred, and myopia for the Spanish Thoroughbred. Astigmatism ≥0.50 D present in both eyes from the same individual was found in 21.7% of all horses examined. Anisometropia ≥1.00 D was diagnosed in 4 out of 129 horses with both visual eyes. Cycloplegia did not statistically affect the refractive state of the evaluated eyes. The equine eye has a refractive state close to emmetropia. Myopia is higher among Spanish Thoroughbred horses than among Crossbred horses. © 2012 American College of Veterinary Ophthalmologists.

Eesti autobiograafilise kirjutuse kujunemisest 18. sajandist Teise maailmasõjani. The Development of Estonian Autobiographical Writing from the 18th Century to the Second World War

Directory of Open Access Journals (Sweden)

Rutt Hinrikus

Full Text Available In this article I examine the development of Estonian autobiographical writing from its first manifestations to published memoirs, and the development of life writing and its diversification. The beginnings of life writing can be traced back to Estonian folk song and Estonian incidental poetry. The Moravian Brethren movement in Estonia in the 18th century promoted the spread of canonical autobiography. The Moravian Brethren offered alternative opportunities for self-realisation for Estonians who were serfs, and were therefore popular with the people. The practice of the Moravian Brethren made use of retelling and writing about the life of the congregation members, which sometimes became suitable biographies in print, especially stories of awakening. Several manuscript biographies have survived from the Brethren times, such as the biographies of Mäletu Jaan and Mihkel Sarapuu. In addition to the history of the Moravian Brethren movement, these biographies give information about the educational situation and living conditions of the people of the time. The Estonian life writing tradition emerged within the reigning Baltic German cultural space thanks to the Estophiles among the Baltic Germans (J. H. Rosenplänter and the first Estonian men of letters; from the early 19th century we have the diary by Rosenplänter, an estophile pastor from Pärnu, and the diary by the Estonian poet, the then-student Kristjan Jaak Peterson, both in the Estonian language. Johann Voldemar Jannsen, the founder of Estonian-language journalism, kept a diary in the German language for a longer period of time; it was usual that the first Estonian intellectuals (Lilli Suburg, and others in the late 19th century wrote in German. Admittedly, the first Estonian-language life history was written by a forward-looking 19th century peasant named Märt Mitt (1833-1912, who was conscious of himself as a historical subject and gave his memoirs, begun in the 1880s, a memorable title

Dieckmann, M; Deegen, E

1991-08-01

Twelve horses with clinical symptoms of a gastric disorder were studied by gastroscopy. Symptoms of gastric disorders were periprandial colic, bruxism, ructus and reflux. Preliminary to gastroscopy the horses were fasted for 24 h. Access to water was not restricted. The gastroscopy could be conducted easily using a fiberscope 2.5 m in length and 11 mm in outer diameter. While ulcers were present in the squamous fundus of all horses only one horse showed ulceration of the glandular fundus. Solitary ulcers near the margo plicatus were found in horses with mild clinical symptoms. In contrast, diffuse gastroesophageal ulceration was accompanied by severe clinical symptoms. Four horses were affected by an acute gastroesophageal ulceration with gastric reflux and subsequent aspiration pneumonia. Two of those horses suffered from acute gastric ulceration 3-4 days following laparatomy. All horses were treated with cimetidine (5 mg/kg bwt/q.i.d.) until clinical symptoms ceased.

The purpose of this study was to gain a better understanding of stock-type horse show competitors' understanding of welfare and level of concern for stock-type show horses' welfare. Data were collected through an online questionnaire that included questions relating to (a) interest and general understanding of horse welfare, (b) welfare concerns of the horse show industry and specifically the stock-type horse show industry, (c) decision-making influences, and (d) level of empathic characteristics. The majority of respondents indicated they agree or strongly agree that physical metrics should be a factor when assessing horse welfare, while fewer agreed that behavioral and mental metrics should be a factor. Respondent empathy levels were moderate to high and were positively correlated with the belief that mental and behavioral metrics should be a factor in assessing horse welfare. Respondents indicated the inhumane practices that most often occur at stock-type shows include excessive jerking on reins, excessive spurring, and induced excessive unnatural movement. Additionally, respondents indicated association rules, hired trainers, and hired riding instructors are the most influential regarding the decisions they make related to their horses' care and treatment.

Distal phalanx fractures in horses: a survey of 274 horses with radiographic assessment of healing in 36 horses

International Nuclear Information System (INIS)

Honnas, C.M.; O'Brien, T.R.; Linford, R.L.

1988-01-01

The case records of 274 horses with fractures of the distal phalanx were reviewed. Fifty-two horses had bilateral forelimb fractures, for a total of 326 distal phalanx fractures. The fractures were classified into one of five previously described types, based on the radiographic anatomic configuration of the fracture. Solar margin fractures, which have been briefly described in other reports and previously classified as type V fractures, were identified in 132 horses. This type of fracture is distinct from other distal phalanx fractures. Due to the high incidence of solar margin fractures, these fractures were classified as a separate type (type VI). Follow-up radiographic examinations to assess fracture healing were available for 36 horses. Twenty-two horses with distal phalanx fractures (three type I, nine type II, two type III, one type IV, one type V, and six type VI) had radiographic evidence of complete bony union of the fracture at a mean of 11 months after injury. Eight horses with conplete type II fractures involving the articular surface had bony union of the body and solar margin, but not the subchondral bone at the articular surface, a mean of 11 months after injury. Six horses (four type II and two type IV) had little radiographic evidence of bony healing during the follow-up period. All fractures that eventually healed had evidence of progression toward bony union by 6 months after injury

Acquisition of noun derivation in Estonian and Russian L1

Reili Argus

2018-04-01

Full Text Available Acquisition of derivation is not a well-studied area in first language research and a comparative approach to the acquisition of derivation in different languages doesn’t exist. There is no information on how a child acquires derivation in a language with a rich and regular system of derivational patterns, or in a language where derivation is productive, but the system of derivational patterns is opaque. According to general ideas of complexity in a language, the child should start to use simplex stems first and, only after that, complex ones, that is, complexity should increase in the course of acquisition. Our paper is intended to address these issues, based on longitudinal child data from typologically different languages, Estonian and Russian. The results revealed significant differences in the acquisition of noun derivation in the two languages under observation. The system of noun derivation is acquired at a faster pace in Russian, while Estonian children have far fewer noun derivatives in their speech and they use different derivation suffixes with less regularity. Even so, the so-called building block model may be applied for both languages only partially.

Az észt névtervezés az észt nyelvpolitikai modell tükrében [The name management in the mirror of the Estonian LPP-model

Directory of Open Access Journals (Sweden)

Pomozi, Péter

2016-12-01

Full Text Available The Estonian model of language planning and policy, which has been serving the development and protection of the Estonian language in its current form since 2004, is one of the most successful of such strategies in Europe. It owes it success to the broad social and scientific consensus reached in questions of language policy, regardless of changes in government. The Development Plan of the Estonian Language divides Estonian language planning and policy into three parts: status planning, corpus planning and prestige planning. Name management is a part of corpus planning, although certain aspects are also connected to legal and prestige planning. Name management strategies are present in all components of the Estonian model of language planning and policy, as linguistically appropriate name use is not only a socio-cultural, but economic question, as informative and easy to understand names contribute to measurable economic advantages. The paper mainly demonstrates the dilemmas and answers of Estonian name management through examples from personal name giving practices, but questions concerning the problems of name use in a multicultural environment and the difficulties of place name and firm name management are also discussed.

Full Text Available The objective of the present study was to analyse the numbers and division of horses of undefined breed. At the present time this group is the most numerous in the entire population of horses. Horses of undefined breed do not come under any breeder union which would provide reports about these horses; these horses are only registered and breeders are informed only about their numbers. Our study is the first to deal with the problem of increasing numbers of horses of undefined breed. The database contained 22 211 horses not entered registered in any of the stud books. In the database we filed approved horses born between 1972 and 1 September 2012 and horses registered from 1987. The data were processed in the Excel programme and results were evaluated in graphs. The most frequent horse in this group was the warm-blood type (n = 9 303, pony type (n = 6 285, cold-blooded type (n = 2 663 and unlisted horses (n = 2 278. Since 2001 the number of registered horses of undefined breed has increased. The most numerous dams of horses of undefined breed is the Czech warm-blood with 1 912 offspring; dams of the English Thoroughbred with 552 offspring and mares of the utility Huzule horse with 492 offspring. In the group of registered horses of undefined breed the Czech warm-blood appears in the pedigree of 507 colts and the American Paint Horse in the pedigree of sires of 506 colts. Why the numbers of horses of undefined breed are increasing is the boom of leisure horsemanship and unqualified horse breeding.

Field of genes: the politics of science and identity in the Estonian Genome Project.

Science.gov (United States)

Fletcher, Amy L

2004-04-01

This case study of the Estonian Genome Project (EGP) analyses the Estonian policy decision to construct a national human gene bank. Drawing upon qualitative data from newspaper articles and public policy documents, it focuses on how proponents use discourse to link the EGP to the broader political goal of securing Estonia's position within the Western/European scientific and cultural space. This dominant narrative is then situated within the analytical notion of the "brand state", which raises potentially negative political consequences for this type of market-driven genomic research. Considered against the increasing number of countries engaging in gene bank and/or gene database projects, this analysis of Estonia elucidates issues that cross national boundaries, while also illuminating factors specific to this small, post-Soviet state as it enters the global biocybernetic economy.

Horseback riding is the most fundamental use of domestic horses and has had a huge influence on the development of human societies for millennia. Over time, riding techniques and the style of riding improved. Therefore, horses with the ability to perform comfortable gaits (e.g. ambling or pacing), so-called 'gaited' horses, have been highly valued by humans, especially for long distance travel. Recently, the causative mutation for gaitedness in horses has been linked to a substitution causing a premature stop codon in the DMRT3 gene (DMRT3_Ser301STOP) [1]. In mice, Dmrt3 is expressed in spinal cord interneurons and plays an important role in the development of limb movement coordination [1]. Genotyping the position in 4396 modern horses from 141 breeds revealed that nowadays the mutated allele is distributed worldwide with an especially high frequency in gaited horses and breeds used for harness racing [2]. Here, we examine historic horse remains for the DMRT3 SNP, tracking the origin of gaitedness to Medieval England between 850 and 900 AD. The presence of the corresponding allele in Icelandic horses (9(th)-11(th) century) strongly suggests that ambling horses were brought from the British Isles to Iceland by Norse people. Considering the high frequency of the ambling allele in early Icelandic horses, we believe that Norse settlers selected for this comfortable mode of horse riding soon after arrival. The absence of the allele in samples from continental Europe (including Scandinavia) at this time implies that ambling horses may have spread from Iceland and maybe also the British Isles across the continent at a later date.

The Role of Language in (Recreating Tatar Diaspora Identity: The Case of the Estonian Tatars

Directory of Open Access Journals (Sweden)

Maarja Klaas

2015-06-01

Full Text Available This paper focuses on the meanings assigned to Tatar language among the Tatar diaspora in Estonia. According to interviews with Estonian Tatars as well as descriptions of field material from Tatarstan, language is an important aspect of Tatar ethnic identity. This paper will track common discourses about the Tatar language and the way it is connected to Tatar ethnic identity. Issues concerning Tatar language are used to demonstrate various ways of enacting Tatarness in Estonia. It is shown that Estonian Tatars worry about the vitality and purity of Tatar language, but for some, marginalization of dialects is also an issue. People categorized with the same identity labels by self and others can experience and enact their Tatarness in a variety of different ways.

This article discusses the benefits and limitations of inhalation therapy in horses. Inhalation drug therapy delivers the drug directly to the airways, thereby achieving maximal drug concentrations at the target site. Inhalation therapy has the additional advantage of decreasing systemic side effects. Inhalation therapy in horses is delivered by the use of nebulizers or pressured metered dose inhalers. It also requires the use of a muzzle or nasal mask in horses. Drugs most commonly delivered through inhalation drug therapy in horses include bronchodilators, antiinflammatories, and antimicrobials.

Full Text Available Nowdays horses are raised and used almost only for sport and recreation and, of course, for meat production. With the possibility of buying fresh horse meat and products based on horse meat, new eating habits have been acquired. The number of horses in the Republic of Croatia has been decreasing continually, which can result in import rather than in export of horse meat, unless a proper and a good breeding plan for horse meat production is made soon. In existing small private slaughter-houses, together with other animals, horses are slaughtered but in a very small number (just to meet the needs of the market. As those horses are of different genetic bases, (mostly cold blooded and cross-bred as well as of different age, sex and physical shape, the slaughter-house yield greatly varies. Due to some injuries, blindenss or lameness horses are killed coercively as to gain minimal profit. In distinction from other animals where the percentage of carcass yield is very high, sloughter-house yield of horse carcass is not high due to a small number of killed animals

Playing with fire - What is influencing horse owners' decisions to not vaccinate their horses against deadly Hendra virus infection?

Directory of Open Access Journals (Sweden)

Kailiea Arianna Goyen

Full Text Available Hendra virus is a zoonotic paramyxovirus, which causes severe respiratory and neurological disease in horses and humans. Since 2012, the Hendra virus sub-unit G vaccine has been available for horse vaccination in Australia. Uptake of the vaccine has been limited and spill-over events of Hendra virus infection in horses continue to occur. We conducted an online, questionnaire-based cross-sectional study of 376 horse owners belonging to a variety of different equestrian clubs in Queensland, Australia, to identify risk factors for non-vaccination against Hendra virus. A total of 43.1% (N = 162 of horse owners indicated that they currently did not vaccinate against Hendra virus infection, while 56.9% (N = 214 currently vaccinated against Hendra virus infection. A total of 52 risk factors were evaluated relating to equestrian activities, horse management, perceived risk and severity of horse and human infection with Hendra virus, side effects of Hendra vaccination, other vaccinations conducted by horse owners and horse owners' attitudes towards veterinarians. The final multivariable logistics regression model identified the following risk factors associated with increased odds of non-vaccination against Hendra virus: 1 perceived low risk (compared to high of Hendra virus infection to horses (considering the horse owners' location and management practices or horse owners were unsure about the risk of infection, 2 perceived moderate severity (compared to very severe or severe of Hendra virus infection in humans, 3 horse owners non-vaccination of their pets, 4 horse owners non-vaccination against strangles disease in horses, 5 handling of more than three horses per week (compared to one horse only and 6 perceived attitude that veterinarians had a high motivation of making money from Hendra virus vaccination (compared to veterinarians having a low motivation of making money from Hendra virus vaccination.

2017-08-01

Although Arabian horses have been bred in strains for centuries and pedigrees have been recorded in studbooks, to date, little is known about the genetic diversity within and between these strains. In this study, we tested if the three main strains of Syrian Arabian horses descend from three founders as suggested by the studbook. We examined 48 horses representing Saglawi (n = 18), Kahlawi (n = 16) and Hamdani (n = 14) strains using the Equine SNP70K BeadChip. For comparison, an additional 24 Arabian horses from the USA and three Przewalski's horses as an out group were added. Observed heterozygosis (H o ) ranged between 0.30 and 0.32, expected heterozygosity (H e ) between 0.30 and 0.31 and inbreeding coefficients (F is ) between -0.02 and -0.05, indicating high genetic diversity within Syrian strains. Likewise, the genetic differentiation between the three Syrian strains was very low (F st  horses. Among Arabian horses, we found three clusters containing either horses from the USA or horses from Syria or horses from Syria and the USA together. Individuals from the same Syrian Arabian horse strain were spread across different sub-clusters. When analyzing Syrian Arabian horses alone, the best population differentiation was found with three distinct clusters. In contrast to expectations from the studbook, these clusters did not coincide with strain affiliation. Although this finding supports the hypothesis of three founders, the genetic information is not consistent with the currently used strain designation system. The information can be used to reconsider the current breeding practice. Beyond that, Syrian Arabian horses are an important reservoir for genetic diversity. © 2017 Stichting International Foundation for Animal Genetics.

Full Text Available Estonian knowledge of history emanates from the fact that constituting an independent nation has for the most part been nothing but a utopia, and was a reality for a relatively short time. When it comes to selfidentification though, the expression ’a singing people’ is often used by the Estonians to describe themselves. Nostalgia for freedom is reflected in the Estonian culture of almost all periods and is carried on by the singing tradition, where patriotic songs emerge independent of different musical tastes within a particular generation and form an important part of a common Estonian repertoire. Patriotic songs occupy a central place in several fields of Estonian culture: besides music culture also in popular culture,and literary history – the works of poetry which have gained the most popularity are those which when put to music have been the most widely spread among the people. The main part of the most popular Estonian patriotic songs are choral songs from the national awakening at the end of the 19th century. Despite the national programmes aiming to wipe out ‘bourgeois nationalism’, they were sung at the song festivals in the Soviet era and were published in song books, expressing the people’s nostalgia for freedom lost. After the end of the Second World War, there was an attempt at launching a kind of patriotic new creation, where patriotism was merged with Soviet pathos; the aim was to show that the people’s utopia was in fact communism, but not a single one of those songs made it into the people’s common repertoire. Only the patriotic songs composed in the 1980s during the so-called new national awakening reached a popularity comparable to that of the old songs. The discourse on ’Estonianness’ and the shaping of a matching repertoire under imperial Russian rule took place under very different circumstances than its preservation and development in the second half of the 20th century under Soviet occupation, but

Humans have shaped the population history of the horse ever since domestication about 5500 years ago. Comparative analyses of the Y chromosome can illuminate the paternal origin of modern horse breeds. This may also reveal different breeding strategies that led to the formation of extant breeds. Recently, a horse Y-chromosomal phylogeny of modern horses based on 1.46 Mb of the male-specific Y (MSY) was generated. We extended this dataset with 52 samples from five European, two American and seven Asian breeds. As in the previous study, almost all modern European horses fall into a crown group, connected via a few autochthonous Northern European lineages to the outgroup, the Przewalski's Horse. In total, we now distinguish 42 MSY haplotypes determined by 158 variants within domestic horses. Asian horses show much higher diversity than previously found in European breeds. The Asian breeds also introduce a deep split to the phylogeny, preliminarily dated to 5527 ± 872 years. We conclude that the deep splitting Asian Y haplotypes are remnants of a far more diverse ancient horse population, whose haplotypes were lost in other lineages. © 2018 Stichting International Foundation for Animal Genetics.

This study investigated the occurrence of wounds in Nigerian horses. The study population was 1,621 horses sold at the Obollo Afor horse lairage in Enugu State, Nigeria, during a 6-month period: 3 months of dry season and 3 months of rainy season (February-April and June-August 2012). A total of 207 horses were systematically sampled and subjected to a comprehensive physical examination. Those with wounds were marked, recorded, and clinically examined. Of the 207 horses sampled, 21 (10.1%) had wounds. The body distribution of the wounds was 9.5% head, 9.5% forelimbs, 19.1% hind limbs, 4.8% tail, 14.3% flank, 9.5% loin, 19.1% hip, 9.5% barrel, and 4.8% croup. The occurrence of the wounds was not significantly associated with sex or season, but the occurrence in adults was significantly (p horses. It was concluded that the occurrence of wounds is relatively high (10.1%), and mainly the hind limbs, hip, and flank of adult horses are affected. It was recommended that horse guardians and handlers should be properly educated on the care of horses.

Horse domestication revolutionized transport, communications, and warfare in prehistory, yet the identification of early domestication processes has been problematic. Here, we present three independent lines of evidence demonstrating domestication in the Eneolithic Botai Culture of Kazakhstan, dating to about 3500 B.C.E. Metrical analysis of horse metacarpals shows that Botai horses resemble Bronze Age domestic horses rather than Paleolithic wild horses from the same region. Pathological characteristics indicate that some Botai horses were bridled, perhaps ridden. Organic residue analysis, using delta13C and deltaD values of fatty acids, reveals processing of mare's milk and carcass products in ceramics, indicating a developed domestic economy encompassing secondary products.

Rutgers Young Horse Teaching and Research Program: sustainability of taking a risk with "at risk" horses.

Ralston, Sarah L; Molnar, Anne

2012-12-01

In 1999, the Young Horse Teaching and Research Program (YHTRP) was initiated at Rutgers University. The unique aspect of the program was using horses generally considered "at risk" and in need of rescue, but of relatively low value. The risks of using horses from pregnant mare urine (PMU) ranches and Bureau of Land Management (BLM) mustangs were high, but, ultimately, unrealized. No students or staff members were seriously injured over the course of the next 12 yr, and the horses were sold annually as highly desirable potential athletes or pleasure horses, usually at a profit. The use of "at risk" horses generated a significant amount of positive media attention and attracted substantial funding in the form of donations and sponsorships, averaging over $60,000 (USD)per year. Despite economic downturns, public and industry support provided sustainability for the program with only basic University infrastructural support. Taking the risk of using "at risk" horses paid off, with positive outcomes for all.

Xenophon on Horses

Directory of Open Access Journals (Sweden)

Alenka Cedilnik

2013-07-01

Full Text Available Based on Xenophon’s writings on horses, the paper begins with a partial account of his life prior to his decision to join Cyrus, and continues by outlining his attitude to horses, animals with whom he lived in close contact. Except for the period spent campaigning with Cyrus’ Greek mercenaries (401–400 BC, the life of Xenophon remains largely unknown, raising a number of still unanswered questions. While the final answers are probably going to remain obscure, it may be surmised – on the basis of his horse writings as well – that the author came from an affluent family. As an Athenian of substance, he would have been classified as a knight, and since the representatives of this class fought in the Athenian cavalry, it was this combat arm to which he would have belonged. There is no hard and fast evidence that he took an active part in the last years of the Peloponnesian War. However, his fairly detailed account of the Athenian developments following the peace treaty suggests that Xenophon remained in the city during the rule of the Thirty Tyrants, when many residents were obliged to leave, and, as a cavalry mem- ber, actively supported the regime to the end. In fact, Xenophon’s presentation of the contemporary events highlights the cavalry’s role to the extent that it appears to have played a crucial part in defending the city and regime. But despite the cavalry’s support of the Thirty, its members do not seem to have flocked out of Athens in the uncertain conditions which followed the fall of the Thirty and the restoration of democracy. Thus Xenophon’s decision to join Cyrus the Younger’s expedition may have been influenced not by his recent support of the Thirty alone, but also by reasons unknown today. While there is no solid proof of his closer association with horses prior to Cyrus’ expedition, Xenophon’s writing in the Anabasis leaves no doubt that he spent at least the greater part of the campaign on horseback.

OBJECTIVE To determine factors affecting race speed in Swedish Standardbred horses undergoing surgery of the carpal flexor sheath (CFS), to investigate whether preoperative racing speed was associated with specific intraoperative findings and whether horses returned to racing, and to compare the performance of horses undergoing surgery of the CFS with that of age- and sex-matched control horses. ANIMALS 149 Swedish Standardbred trotters undergoing surgery of the CFS and 274 age- and sex-matched control horses. PROCEDURES Medical records of CFS horses were examined. Racing data for CFS and control horses were retrieved from official online records. Generalizing estimating equations were used to examine overall and presurgery racing speeds and the association of preoperative clinical and intraoperative findings with preoperative and postoperative speeds. Multivariable regression analysis was used to examine career earnings and number of career races. Kaplan-Meier survival analysis was used to compare career longevity between CFS and control horses. RESULTS CFS horses were significantly faster than control horses. The CFS horses that raced before surgery were slower as they approached the surgery date, but race speed increased after surgery. There were 124 of 137 (90.5%) CFS horses that raced after surgery. No intrathecal pathological findings were significantly associated with preoperative racing speed. Career longevity did not differ between CFS and control horses. CONCLUSIONS AND CLINICAL RELEVANCE Horses undergoing surgery of the CFS had a good prognosis to return to racing after surgery. Racing careers of horses undergoing surgery of the CFS were not significantly different from racing careers of control horses.

Non-surgical sterilisation methods may offer a sustainable solution to feral horse (Equus caballus) overpopulation.

Feral horses are a significant pest species in many parts of the world, contributing to land erosion, weed dispersal and the loss of native flora and fauna. There is an urgent need to modify feral horse management strategies to achieve public acceptance and long-term population control. One way to achieve this is by using non-surgical methods of sterilisation, which are suitable in the context of this mobile and long-lived species. In this review we consider the benefits of implementing novel mechanisms designed to elicit a state of permanent sterility (including redox cycling to generate oxidative stress in the gonad, random peptide phage display to target non-renewable germ cells and the generation of autoantibodies against proteins essential for conception via covalent modification) compared with that of traditional immunocontraceptive approaches. The need for a better understanding of mare folliculogenesis and conception factors, including maternal recognition of pregnancy, is also reviewed because they hold considerable potential in providing a non-surgical mechanism for sterilisation. In conclusion, the authors contend that non-surgical measures that are single shot and irreversible may provide a sustainable and effective strategy for feral horse control.

Osteogenesis imperfecta (OI) is a rare bone disorder. In 90% of cases, OI is caused by mutations in the COL1A1/2 genes, which code procollagen α1 and α2 chains. The main aim of the current research was to identify the mutational spectrum of COL1A1/2 genes in Estonian patients. The small population size of Estonia provides a unique chance to explore the collagen I mutational profile of 100% of OI families in the country. We performed mutational analysis of peripheral blood gDNA of 30 unrelated Estonian OI patients using Sanger sequencing of COL1A1 and COL1A2 genes, including all intron-exon junctions and 5'UTR and 3'UTR regions, to identify causative OI mutations. We identified COL1A1/2 mutations in 86.67% of patients (26/30). 76.92% of discovered mutations were located in the COL1A1 (n = 20) and 23.08% in the COL1A2 (n = 6) gene. Half of the COL1A1/2 mutations appeared to be novel. The percentage of quantitative COL1A1/2 mutations was 69.23%. Glycine substitution with serine was the most prevalent among missense mutations. All qualitative mutations were situated in the chain domain of pro-α1/2 chains. Our study shows that among the Estonian OI population, the range of collagen I mutations is quite high, which agrees with other described OI cohorts of Northern Europe. The Estonian OI cohort differs due to the high number of quantitative variants and simple missense variants, which are mostly Gly to Ser substitutions and do not extend the chain domain of COL1A1/2 products.

Radon in Estonian buildings. Establishment of a measurement system and obtained results

One purpose of this project was the establishment of a radon monitoring programme inside the state environmental monitoring programme. Another purpose was to investigate regions, expected to have high radon levels indoors. A new method for the long-term measurement of indoor radon was established and the staff for these measurements was trained. The results of the measurement can be used by Estonian decision-makers to work out rules and standards. There is no legislative act in the field of radiation in Estonian at this time. To summarize the results of the measurements we can say that indoor radon concentrations vary by region. The radon investigations must be continued to identify the risk areas and types of housing construction. The results of the state radon monitoring are provided to the municipalities, who advice the owners of planned new houses to select the right construction for the house. A new project will follow with an investigation of radon in randomly selected dwellings, training and equipment for radon measurement in soil, and general advice with regard to radon, as well as assistance in preparing information about radon. 7 refs, 5 figs

Outcomes associated with arthrodesis of the proximal interphalangeal (PIP) joint in Quarter Horses used for Western performance activities are well documented but little is known regarding outcomes for other types of horses. To identify factors associated with outcomes, including breed and activity, after arthrodesis of the PIP joint in Warmbloods, Thoroughbreds and Quarter Horses. Retrospective case series. Surgical case records of 82 Quarter Horses principally engaged in Western performance and Thoroughbred or Warmblood breeds principally engaged in showing, showjumping and dressage, with arthrodesis of the PIP joint were reviewed. Arthrodesis was performed with either 3 transarticular cortex bone screws placed in lag fashion, a dynamic compression plate (DCP) with 2 transarticular cortex bone screws placed in lag fashion, or a locking compression plate (LCP) with 2 transarticular cortex bone screws placed in lag fashion. Demographic data, clinical presentation, radiographic findings, surgical technique, post operative treatment and complications were recorded. Long-term follow-up was obtained for all 82 horses. Osteoarthritis of the PIP joint was the most common presenting condition requiring arthrodesis, which was performed with either the 3 screw technique (n = 41), DCP fixation (n = 22), or LCP fixation (n = 19). Post operatively, 23/31 (74%) Warmbloods/Thoroughbreds and 44/51 (87%) Quarter Horses achieved successful outcomes. Thirteen of 23 (57%) Warmbloods/Thoroughbreds and 24 of 38 (63%) Quarter Horses, used for athletic performance, returned to successful competition. Within this subgroup of horses engaged in high-level activity, regardless of breed type, horses undergoing hindlimb arthrodesis were significantly more likely to return to successful competition (73%; 33/45) than those with forelimb arthrodesis (25%; 4/16, P = 0.002). Arthrodesis of the PIP joint in Warmbloods/Thoroughbreds and Quarter Horses results in a favourable outcome for return to

The clinical signs, laboratory data, results of nuclear scintigraphy and radiographic examination of five horses with vertebral body osteomyelitis are described together with response to treatment. Three horses were less than five months of age. Four horses demonstrated hindlimb paresis and in three a focus of pain in the thoracolumbar region could be identified. An umbilical abscess, a caudal lobe lung abscess and a patent urachus were considered primary niduses of infection in each of three horses. Leucocytosis, neutrophilia, anaemia and elevated fibrinogen were the most consistent laboratory abnormalities. Nuclear scintigraphy was performed in three horses and identified the site of the vertebral lesion which was subsequently evaluated radiographically. In the other two horses radiographic examination in the region of areas of focal pain identified a lesion. Radiographic abnormalities included compression fractures of vertebral bodies (two), proliferative new bone (three) and soft tissue swelling ventral to a vertebral body (one). Two horses, including one with a compression fracture of the second lumbar vertebra, received parenteral antimicrobial therapy for 40 and 74 days, respectively. When re-examined six months later they showed no neurological abnormalities. The other three horses failed to respond to antimicrobial treatment and were humanely destroyed. The horse with a lung abscess also had an abscess cranial to the right tuber coxae which extended into the vertebral bodies of the third and fourth lumbar vertebrae from which Streptococcus zooepidemicus was cultured. A horse with proliferative new bone on the ventral aspect of the fifth and sixth thoracic vertebrae had a mediastinal mass associated with these vertebrae and fungal granulomas, from which Aspergillus species was cultured, in the heart and aorta, trachea, spleen and kidney. The horse with a patent urachus and soft tissue swelling ventral to the vertebral body of the 12th thoracic vertebra

Whole mitochondrial genome sequencing of domestic horses reveals incorporation of extensive wild horse diversity during domestication

Full Text Available Abstract Background DNA target enrichment by micro-array capture combined with high throughput sequencing technologies provides the possibility to obtain large amounts of sequence data (e.g. whole mitochondrial DNA genomes from multiple individuals at relatively low costs. Previously, whole mitochondrial genome data for domestic horses (Equus caballus were limited to only a few specimens and only short parts of the mtDNA genome (especially the hypervariable region were investigated for larger sample sets. Results In this study we investigated whole mitochondrial genomes of 59 domestic horses from 44 breeds and a single Przewalski horse (Equus przewalski using a recently described multiplex micro-array capture approach. We found 473 variable positions within the domestic horses, 292 of which are parsimony-informative, providing a well resolved phylogenetic tree. Our divergence time estimate suggests that the mitochondrial genomes of modern horse breeds shared a common ancestor around 93,000 years ago and no later than 38,000 years ago. A Bayesian skyline plot (BSP reveals a significant population expansion beginning 6,000-8,000 years ago with an ongoing exponential growth until the present, similar to other domestic animal species. Our data further suggest that a large sample of wild horse diversity was incorporated into the domestic population; specifically, at least 46 of the mtDNA lineages observed in domestic horses (73% already existed before the beginning of domestication about 5,000 years ago. Conclusions Our study provides a window into the maternal origins of extant domestic horses and confirms that modern domestic breeds present a wide sample of the mtDNA diversity found in ancestral, now extinct, wild horse populations. The data obtained allow us to detect a population expansion event coinciding with the beginning of domestication and to estimate both the minimum number of female horses incorporated into the domestic gene pool and the

Re-conceptualizing mother tongue tuition of Estonian abroad as a transnational phenomenon

Directory of Open Access Journals (Sweden)

Maarja Siiner

2017-05-01

Full Text Available The governmental initiative called the Compatriots Programme, which supports language tuition in Estonian schools and societies abroad, reveals an increased interest in developing intergenerational language transmission in the growing Estonian diaspora. This transnational language political activity signals a new era in language policy, where nation states are increasingly decentralized by migration. The evaluation of the program furthermore reveals that organizing such schools requires a willingness to take language political agency, typically conducted by well-educated and well-integrated resourceful transnational multilingual parents. The present article outlines the results of an ethnographic study of the process of establishing the Estonian School in Copenhagen. This step has demanded a change in the mindset still prevailing in Estonia that language political activities, such as planning language acquisition, are solely the responsibility of the state. Since the prevailing language ideology in Denmark is not favorable towards multilingualism in migrant languages, intergenerational language transmission furthermore presupposes a feeling of ownership of the language and high language self-esteem.

In order to assess the relevance of horses as a possible reservoir of Salmonella and Shigatoxin-producing Escherichia coli (STEC), 400 samples of horse faeces and 100 samples of horse meat products were examined by PCR-screening methods. Salmonella enterica was not found in any of the samples. One faeces-sample and one horse meat product were proved to be STEC positive. The STEC-strain from faecal origin belonged to the serotype 0113:H21 and had the stx 2c gene and the enterohemolysin gene. The STEC-strain isolated from a horse meat product had the serotype O87:H16 and the stx 2d gene. The results indicate a very low risk for human to get a Salmonella- or EHEC- infection from horses in Germany.

2004-08-01

We compared the genetic diversity and distance among six German draught horse breeds to wild (Przewalski's Horse), primitive (Icelandic Horse, Sorraia Horse, Exmoor Pony) or riding horse breeds (Hanoverian Warmblood, Arabian) by means of genotypic information from 30 microsatellite loci. The draught horse breeds included the South German Coldblood, Rhenish German Draught Horse, Mecklenburg Coldblood, Saxon Thuringa Coldblood, Black Forest Horse and Schleswig Draught Horse. Despite large differences in population sizes, the average observed heterozygosity (H(o)) differed little among the heavy horse breeds (0.64-0.71), but was considerably lower than in the Hanoverian Warmblood or Icelandic Horse population. The mean number of alleles (N(A)) decreased more markedly with declining population sizes of German draught horse breeds (5.2-6.3) but did not reach the values of Hanoverian Warmblood (N(A) = 6.7). The coefficient of differentiation among the heavy horse breeds showed 11.6% of the diversity between the heavy horse breeds, as opposed to 21.2% between the other horse populations. The differentiation test revealed highly significant genetic differences among all draught horse breeds except the Mecklenburg and Saxon Thuringa Coldbloods. The Schleswig Draught Horse was the most distinct draught horse breed. In conclusion, the study demonstrated a clear distinction among the German draught horse breeds and even among breeds with a very short history of divergence like Rhenish German Draught Horse and its East German subpopulations Mecklenburg and Saxon Thuringa Coldblood.

Keeping horses in groups: A review

Hartmann, Elke; Søndergaard, Eva; Keeling, Linda J.

2012-01-01

Although husbandry conditions for horses have improved over the last decades, many horses are still kept singly with limited or no physical contact to other horses. This is surprising, given the fact that keeping horses in groups is recognised best to fulfil their physical and behavioural needs......, especially their need for social contact with conspecifics, as well as to have a beneficial effect on horse–human interactions during training. Group housing of farm animals is widely applied in practice. As a consequence, scientists have investigated numerous aspects of group housing to help further improve...... animal welfare and human–animal interactions under these conditions. However, compared to this literature available in farm animals, and the plentiful studies conducted of feral horse populations, there is much less done when it comes to the management of horses kept in groups in the domestic environment...

Fractures of the medial intercondylar eminence of the tibia (MICET) are scarcely reported in horses. To report the clinical and diagnostic findings, surgical treatment and outcome in a series of horses presented with MICET fracture and treated with arthroscopic fragment removal. Multicentre retrospective case series. Case records of horses diagnosed with MICET fractures that had undergone surgical treatment were reviewed. Follow-up information was obtained from re-examination visits and/or owners. Twenty-one cases were identified at 9 equine hospitals between 2004 and 2016. A history of trauma and acute onset of lameness was reported in 12 horses. All cases underwent fracture removal via arthroscopy of the medial femorotibial joint. The cranial cruciate ligament was intact in 6 horses and damaged in 15 horses (damage was ≤25% [n = 9], 25-50% [n = 4] or ≥50% [n = 2] of the cross-sectional area). The cranial ligament of the medial meniscus was damaged in 11 horses (≤25% [n = 8], 25-50% [n = 3]). The medial meniscus was damaged in 5 horses and articular cartilage damage was identified in 14 horses (mild [n = 8], moderate [n = 6]). Follow-up information (median 14 months; 4 months-6 years) was available for 20 cases; 2 horses were sound but convalescing; 13 horses were sound and returned to their previous or expected use. Of the 4 horses with the most severe changes to the articular soft tissue structures, 2 remained lame and 2 were subjected to euthanasia because of persistent lameness. The retrospective, multicentre nature of this study and the limited number of horses are the main limitations. Fractures of the MICET are commonly associated with a traumatic event. Prompt diagnosis and early arthroscopic removal of the fracture are recommended. © 2017 The Authors. Equine Veterinary Journal published by John Wiley & Sons Ltd on behalf of EVJ Ltd.

Periorbital skull fractures were diagnosed in 5 horses, and were associated with ophthalmic complications including corneal ulceration, uveitis, and entrapment of the eye by retrobulbar bone fragments. Physical examination was of greater diagnostic use than radiography. Surgical repair was performed on all horses and was associated with a more favorable postoperative appearance in horses treated acutely; however, the cosmetic results were considered acceptable in all horses. Major postoperative complications were not observed

Full Text Available Changes in the Estonian National Museum from 1909 to the presentThe Estonian National Museum was founded in Tartu in 1909 as part of the national movement. With its activities and connections in society, the ENM helped create Estonian society, the nation’s collective memory and identity.The ENM has always been – despite the changing locations, names, and content – one of the symbols of national identity. But at the same time, ENM has never had its own building designed specially for the museum’s purposes.Since 1909 there have been several attempts to establish a home for the ENM. At first (1909–1923, Estonian society wanted to establish the museum in the center of Tartu. The museum was intended to become a key institution of the growing nation and establishing the nation’s identity.At last in 1923 the ENM secured the Raadi manor, outside the center of the city, in a beautiful park, near the lake with its boats and water attractions. In this manor the first permanent exhibition of mainly 19th century Estonian peasant life was compiled, and the ENM operated in the Raadi manor from 1923–1940 as the “Estonian’s own museum” The years of alternating occupations, World War II, and political terror damaged and destroyed the whole society. The Raadi manor was destroyed in the war too, and the ENM itself was divided into two parts – the State Ethnographic Museum and the State Literary Museum. The collections of the ENM were given to Tallinn and to many different places inside and outside Tartu. Then began “the period of temporary location” that continues today. The museum is located in several places in the city of Tartu.In 1988, the prior name of the State Ethnographic Museum – the Estonian National Museum – was reinstated. Since the 1990s there have been many attempts to secure a special building for the ENM. Now, at last, as a result of serious economic pressure, we are closer to this goal than ever.

OBJECTIVE To evaluate in vitro phagocytosis and bactericidal activity of circulating blood neutrophils in horses with severe equine asthma and control horses and to determine whether circulating blood neutrophils in horses with severe equine asthma have an increase in expression of the proinflammatory cytokine tumor necrosis factor (TNF)-α and the chemokine interleukin (IL)-8 and a decrease in expression of the anti-inflammatory cytokine IL-10 in response to bacteria. ANIMALS 6 horses with severe equine asthma and 6 control horses. PROCEDURES Circulating blood neutrophils were isolated from horses with severe equine asthma and control horses. Phagocytosis was evaluated by use of flow cytometry. Bactericidal activity of circulating blood neutrophils was assessed by use of Streptococcus equi and Streptococcus zooepidemicus as targets, whereas the cytokine mRNA response was assessed by use of a quantitative PCR assay. RESULTS Circulating blood neutrophils from horses with severe equine asthma had significantly lower bactericidal activity toward S zooepidemicus but not toward S equi, compared with results for control horses. Phagocytosis and mRNA expression of TNF-α, IL-8, and IL-10 were not different between groups. CONCLUSIONS AND CLINCAL RELEVANCE Impairment of bactericidal activity of circulating blood neutrophils in horses with severe equine asthma could contribute to an increased susceptibility to infections.

The objective of this study was to assess differences in serum protein expression profiles of Przewalski's (Mongolian wild horse) and thoroughbred horses using proteome analysis. The serum proteins were separated by two-dimensional electrophoresis (2-DE) and five different gene products were identified. Proteins represented by the five spots were identified by matrix-assisted laser desorption ionization-time-of-flight (MALDI-TOF) mass spectrometry (MS)/MS technology. The identities of all proteins were deduced based on their similarity to proteins in the human plasma protein database. Three proteins (a haptoglobin-2 alpha glycoprotein and two haptoglobin-2beta glycoproteins with different accession numbers) were downregulated in Przewalski's horse sera compared to thoroughbred horse sera. Moreover, two proteins (tetraspanin-18 and pM5) were upregulated in Przewalski's horses compared to thoroughbred horses. Haptoglobin-2 alpha and haptoglobin-2beta may serve as candidate molecules in future studies of inflammation, coagulation, immune modulation and pro-oxidant and antioxidant activity with consequential effects on the entire metabolism of the horse. © 2014 Japanese Society of Animal Science.

Full Text Available This article aims to give an overview of literary instruction in schools of the russification era at the beginning of the 20th century in Estonia; this was likewise the curriculum of literary study offered to the generation of educated youth which included the Young Estonians. Based on official documents, archival materials, and memoirs, and through analyses of anthologies, literary histories, and teaching methods in use at the time, we attempt to reconstruct the outlines of literary reading and requirements for students in various types of schools. When, as a result of school reform, Russian became the language of instruction; lessons in Russian became central in the curriculum, alongside the word of God; selections from Russian literature were read in the original language. In the lower grades, teaching was by the so-called ”natural method”, intended to guarantee swift achievement of fluency in ”living Russian language”; this was later replaced by systematic textual analysis, which distinguished between belles lettres and other types of texts. However, the study of literature was always subordinated to the goals of language instruction. In institutions of secondary education, study of Russian literature was separate from language instruction. Indeed, Russian literature was the only literature systematically studied in high schools (though one must keep in mind that not all schools completely followed the official program. Private schools were especially noticeable for their greater freedom, though all of them had to take general curriculum directives into account. Reading of literary texts connected with other languages thus had to remain almost purely illustrative. In view of the above, in the upper grades of elementary school and high school, students obtained a thorough introduction to the Russian classics. According to the official school curriculum, Russian literary history ended with Nikolai Gogol. Attempts were made to ignore

2016-01-01

To describe the surgical treatment outcome of cervical fractures in 3 horses. Case report. Three client-owned horses with cervical vertebral fractures. Three horses were refered for neck stiffness, pain, and ataxia after a cervical trauma because of a fall. Radiographic examination showed an oblique displaced fracture of the caudal aspect of the body of the second cervical vertebra (C2) in horse 1, an oblique displaced fracture of the caudal aspect of C4 involving the disc between C4 and C5 in horse 2, and a displaced transverse fracture of the body of the axis (C2) extending to the lateral arches and involving the vertebral canal in horse 3. In horse 1, the fracture was reduced and stabilized using a 14-hole narrow DCP plate, applied ventrally, and fixed with cancellous screws. A cervical fusion was performed. In horses 2 and 3, fracture fixation was performed using a 5-hole narrow LCP and 5 mm locking screws. All horses showed improvement and returned to full activity. The fracture healed in all horses. Internal fixation of cervical fracture in these horses was associated with minimal complications, and was associated with healing and a highly functional outcome in all horses. The LCP was preferred and would be recommended for ventral stabilization of selected cases of vertebral fractures. © Copyright 2015 by The American College of Veterinary Surgeons.

How to Improve the Supportive Role of Estonian Innovation System toward Launching New Products by High Technology Companies?

Directory of Open Access Journals (Sweden)

Liisi Sepp

2013-01-01

Full Text Available The purpose of the study is to evaluate how supportive is Estonian national innovation system toward the launching of new innovative products by high technology firms. The article intends to combine two broad areas of research – national innovation system approach and the different models of the new product launching. Based on the literature review and in-depth analysis of three case studies of Estonian high-tech company’s major barriers as well success factors of highly innovative product launches were identified. The barriers of the new product launching were linked with the systemic failures of the national innovation system. The most relevant failures of Estonian national innovation system inhibiting the new product development are capability and networking failures. The sources of innovation of high-technology firms are too narrow, linkages with domestic firms and higher education institutions as well with foreign firms are poorly developed. High-tech firms have also serious capacity problems due to the extremely weak support mechanism by national innovation system on the seed funding stage of product development and prototype building stage as well. Paper argues that resources needed for the innovation should not be looked too narrowly following linear innovation model approach. Instead interactive approach is needed, which combines capability building, network development, interactive learning with direct investments into fundamental research.

Entomologic evaluation of insect hypersensitivity in horses.

Science.gov (United States)

Greiner, E C

1995-04-01

Potential methods of incriminating insects as the cause of insect hypersensitivity are presented. A listing of the biting midges known to attack horses in North America is presented also. An example of how species may be determined to be the cause of the hypersensitivity is given using data from a recent study in Florida. Light trap collections indicated the temporal and geographic distribution of potential contributing species and collections made by vacuuming horses further delineated species by proving they feed on horses and the correct locations on the horses to match lesion distribution. Culicoides hypersensitivity in horses in Florida seems to be caused by a series of species active and feeding on the horses at different times of the year.

European domestic horses originated in two holocene refugia.

Directory of Open Access Journals (Sweden)

Vera Warmuth

2011-03-01

Full Text Available The role of European wild horses in horse domestication is poorly understood. While the fossil record for wild horses in Europe prior to horse domestication is scarce, there have been suggestions that wild populations from various European regions might have contributed to the gene pool of domestic horses. To distinguish between regions where domestic populations are mainly descended from local wild stock and those where horses were largely imported, we investigated patterns of genetic diversity in 24 European horse breeds typed at 12 microsatellite loci. The distribution of high levels of genetic diversity in Europe coincides with the distribution of predominantly open landscapes prior to domestication, as suggested by simulation-based vegetation reconstructions, with breeds from Iberia and the Caspian Sea region having significantly higher genetic diversity than breeds from central Europe and the UK, which were largely forested at the time the first domestic horses appear there. Our results suggest that not only the Eastern steppes, but also the Iberian Peninsula provided refugia for wild horses in the Holocene, and that the genetic contribution of these wild populations to local domestic stock may have been considerable. In contrast, the consistently low levels of diversity in central Europe and the UK suggest that domestic horses in these regions largely derive from horses that were imported from the Eastern refugium, the Iberian refugium, or both.

BREEDING AND UTILIZATION OF ARABIAN HORSE TODAY

Full Text Available Arab horse raising has a hundred year old tradition. A real stud farm raising started by purchasing original reproductive material from Asia in 1895, 1897 and 1899. Apart from state stud in Goražde, Arab horse was also raised in several private stud farms, especially in Slavonia and Srijem region. By the end of the II World war Arab horse raising was restricted to only 2-3 stud farms, regardless the above mentioned oldest Arab stud farm Goražde. According to reports refering to end of 1940 in former Yugoslavia there were slightly more than 150 grown up thoroughbred Arab heads, stallions and mares in both private and public property. A number of well known stud farms was reduced, thus, Arab horse raising was limited only to stud farms Goražde, Inocens Dvor and Karađorđevo. Sires were mostly used in Bosnian-mountain horse breeding whereas in plain areas they were used for ceossing with heavy draft mares or raising of, in that time numerous represented, nonius breed. The year 1970 was characterized by Arab horses reduction, thereby raising stagnation. Horse raising was closed, so, 77 Sabich stallion, bought in Germany, started again Arab horse raising, firstly in Goražde. It was also attributed by raising establishment of agricultural economy Višnjica near Slatina. At the same time Arab horse raising increased slowly at individual raisers in Kutina, Vrbovsko, Istria, Čađavica and Zagreb vicinity. According to available data from 1999 there were approx. 132 stallions and mares due to horse raisers scattered throught Croatia. All male and female reproductive heads were mostly used as raising heads for thoroughbred raising or for crossing with other breeds which is justified by the data from the period 1930-1935. On the other hand one part of reproductive heads, especially males, were used as sports heads for gallop races and distance riding as Arab horses were used by their arrival to present areas and by Arab horse raising tradition.

2016-11-01

Full Text Available Abstract Background Currently about 26,000 horses are breeding in Korea and 57.2% (14,776 horses of them are breeding in Jeju island. According to the statistics published in 2010, the horses breeding in Jeju island are subdivided into Jeju horse (6.1%, Thoroughbred (18.8% and Halla horse (75.1%. Halla horses are defined as a crossbreed between Jeju and Thoroughbred horses and are used for horse racing, horse riding and horse meat production. However, little research has been conducted on Halla horses because of the perception of crossbreed and people’s weighted interest toward Jeju horses. Method Using 17 Microsatellite (MS Markers recommended by International Society for Animal Genetics (ISAG, genomic DNAs were extracted from the hair roots of 3,880 Halla horses breeding in Korea and genetic diversity was identified by genotyping after PCR was performed. Results and conclusion In average, 10.41 alleles (from 6 alleles in HTG7 to 17 alleles in ASB17 were identified after the analysis using 17 MS Markers. The mean value of Hobs was 0.749 with a range from 0.612(HMS1 to 0.857(ASB2. Also, it was found that Hexp and PIC values were lowest in HMS1 (0.607 and 0.548, respectively, and highest in LEX3(0.859 and 0.843, respectively, and the mean value of Hexp was 0.760 and that of PIC was 0.728. 17 MS markers used in this studies were considered as appropriate markers for the polymorphism analysis of Halla horses. The frequency for the appearance of identical individuals was 5.90 × 10−20 when assumed as random mating population and when assumed as half-sib and full-sib population, frequencies were 4.08 × 10−15 and 3.56 × 10−8, respectively. Based on these results, the 17 MS markers can be used adequately for the Individual Identification and Parentage Verification of Halla horses. Remarkably, allele M and Q of ASB23 marker, G of HMS2 marker, H and L of HTG6 marker, L of HTG7 marker, E of LEX3 marker were the specific alleles

The dangers associated with horse riding, a popular activity throughout Australia, are well documented; yet, few studies have comprehensively described injuries caused by horses to nonriders. This study aimed to facilitate targeted injury prevention strategies and appropriate trauma management by describing all horse-related injuries, for both riders and nonriders, in Queensland, and identifying those at greatest risk. Horse-related injury data from 2005 to 2009 were extracted from the Queensland Trauma Registry. Descriptive comparisons were undertaken for demographic, injury, and acute care characteristics between riders and nonriders, between pediatric and adult cases, and between sports/leisure and work injuries. The relative risk of surgery by sex and between riders and nonriders was assessed. More than 25% of injuries occurred in people not riding a horse. Nonriders sustained a significantly higher proportion of internal organ injuries, open wounds, as well as facial and pelvic/abdominal injuries. Females accounted for more than 80% of children who were injured while riding a horse. For adults, 25% were injured while working, and more than 66% of injured workers were male. Injuries most commonly occurred in regional areas. Surgery was most common among children, nonriders, and those with Injury Severity Score (ISS) of 1 to 8. The likelihood of surgery was 25% higher for nonriders (95% confidence interval, 1.14-1.38%). Horse-related injuries are most prevalent in identifiable populations, particularly young female riders and adult males injured while working. Injuries inflicted by horses to nonriders contribute more than 27% of all horse-related injuries; however, most previous research has been limited to injured riders. Compared with riders, nonriders more frequently sustain internal, facial, and pelvic injuries; are male; and undergo surgery. The results of this study may be used to tailor prevention strategies and inform trauma management specific to the

The secondary outcome was to examine the use of helmets and adult supervision. Traumatic brain injury (TBI) was examined in relation to helmet use. Morbidity and mortality were also recorded. Included were all patients presenting with any horse-related trauma to the Royal Children's Hospital in Brisbane from January 2008 to August 2014. Data were retrospectively collected on patient demographics, hospital length of stay (LOS), mechanism of injury (MOI), safety precautions taken, diagnoses and surgical procedures performed. Included in the analysis were 187 incidents involving 171 patients. Most patients were aged 12-14 years (36.9%) and female (84.5%). The most common MOI were falls while riding horses (97.1%). Mild TBI (24.6%) and upper limb fractures (20.9%) were common injuries sustained. Patients who wore helmets had significantly reduced hospital LOS and severity of TBI when compared with those who did not wear helmets (P horses, in addition to being a compulsory requirement whilst horse riding.

The dominance of indirect taxes in Estonian state budget. Summary:Kaudsete maksude dominant Eesti riigieelarve tuludes

2013-09-01

Full Text Available Recession has sharply erected the question of tax burden and the optimal proportion of different kinds of taxes among the incomes of the budget. Indirect taxes and consumption taxes, which proportion is different according to different methodologies, dominate in Estonian state budget. The buoyancy of a tax system based on taxes of that kind is especially weak during the recession. The purpose of Estonian government’s economic policy during the highest peak of crisis was to keep the budget in balance. Instead of recovering economy the taxes were arisen and costs were reduced. The results of such a policy aren’t still clear. Difficulties concerning the incomes of budget have arisen the necessity for lifting taxes, which is possible as the tax burden is low now. But a sharp question of the optimal level of taxes is going to be raised. A formula for indirect tax optimum according to Ramsey taxes and Slutski decomposition has been proposed in the article

A total of 219 and 124 individual fecal samples of horses and donkeys, respectively, were screened for the presence of Cryptosporidium spp., Encephalitozoon spp., and Enterocytozoon bieneusi DNA by genus-specific nested PCR. Isolates were genotyped by sequence analysis of SSU rRNA, GP60, TRAP-C1, COWP, and HSP70 loci in Cryptosporidium, and the ITS region in microsporidia. Cryptosporidium spp. was detected on 3/18 horse farms and 1/15 farms where donkeys were kept. Overall, five (2.3%) horse and two (1.6%) donkey specimens were PCR positive for Cryptosporidium. Genotyping at SSU and GP60 loci revealed that three isolates from horses and donkeys were C. parvum subtype family IIaA16G1R1, one isolate from a horse was, C. muris RN66, and one isolate from a donkey was C. muris TS03. An isolate from a horse shared 99.4% and 99.3% similarity with Cryptosporidium hominis and C. cuniculus, respectively, at the SSU locus. This isolate shared 100% identity with C. hominis at the TRAP-C1, COWP, and HSP70 loci, and it was from the novel gp60 subtype family IkA15G1. Microsporidia were found on 6/18 horse and 2/15 donkey farms. E. bieneusi was identified in 6.8% (15/219) and 1.6% (2/124), and Encephalitozoon cuniculi was identified in 1.8% (4/219) and 1.6% (2/124), of horses and donkeys, respectively. Three genotypes of E. cuniculi (I, II and III) were detected in horses, and E. cuniculi genotype II was detected in donkeys. Four genotypes of E. bieneusi (horse1, horse 2, CZ3, D) were described in horses. An additional five horses and two donkeys were positive for E. bieneusi, but the isolated were not genotyped. Neither Cryptosporidium nor microsporidia prevalence were affected by sex, age, type of breeding, or whether the host was a horse or a donkey. Copyright © 2015 Elsevier B.V. All rights reserved.

Managing a horse stable involves risks, which can have serious consequences for the stable, employees, clients, visitors and horses. Existing industrial or farm production risk management tools are not directly applicable to horse stables and they need to be adapted for use by managers of different types of stables. As a part of the InnoEquine project, an innovative web tool, InnoHorse, was developed to support horse stable managers in business, safety, pasture and manure management. A literature review, empirical horse stable case studies, expert panel workshops and stakeholder interviews were carried out to support the design. The InnoHorse web tool includes a safety section containing a horse stable safety map, stable safety checklists, and examples of good practices in stable safety, horse handling and rescue planning. This new horse stable safety management tool can also help in organizing work processes in horse stables in general.

Response of induced bone defects in horses to collagen matrix containing the human parathyroid hormone gene.

2004-09-01

To determine whether human parathyroid hormone (hPTH) gene in collagen matrix could safely promote bone formation in diaphyseal or subchondral bones of horses. 8 clinically normal adult horses. Amount, rate, and quality of bone healing for 13 weeks were determined by use of radiography, quantitative computed tomography, and histomorphometric analysis. Diaphyseal cortex and subchondral bone defects of metacarpi were filled with hPTH(1-34) gene-activated matrix (GAM) or remained untreated. Joints were assessed on the basis of circumference, synovial fluid analysis, pain on flexion, lameness, and gross and histologic examination. Bone volume index was greater for cortical defects treated with hPTH(1-34) GAM, compared with untreated defects. Bone production in cortical defects treated with hPTH(1-34) GAM positively correlated with native bone formation in untreated defects. In contrast, less bone was detected in hPTH(1-34) GAM-treated subchondral bone defects, compared with untreated defects, and histology confirmed poorer healing and residual collagen sponge. Use of hPTH(1-34) GAM induced greater total bone, specifically periosteal bone, after 13 weeks of healing in cortical defects of horses. The hPTH(1-34) GAM impeded healing of subchondral bone but was biocompatible with joint tissues. Promotion of periosteal bone formation may be beneficial for healing of cortical fractures in horses, but the delay in onset of bone formation may negate benefits. The hPTH(1-34) GAM used in this study should not be placed in articular subchondral bone defects, but contact with articular surfaces is unlikely to cause short-term adverse effects.

The horse has a unique place in European society. Historically, it has played a major part in shaping political and agricultural advances. Today, the horse has diverse roles ranging from the companion and leisure horse, to the sporting athlete. The horse continues to work on the land in many European countries, it serves in the police and the armed forces, and in some regions is a source of food. This has resulted in a vast range of horse-human interactions and relationships. Despite the l...

Considering the hidden mode of inheritance of some coat-color-associated alleles, we investigated the presence/absence of coat-color-associated alleles in 1093 domestic horses of 55 breeds and 20 specimens of Przewalski's horse. For coat-color genotyping, allele specific PCR, pyrosequencing and Li-Cor analyses were conducted on 12 coat-color-associated alleles of five genes. Our data provide deep insight into the distribution of coat-color-associated alleles within breeds. We found that the alleles for the basic colorations (bay, black, and chestnut) are widely distributed and occur in nearly all breeds. Alleles leading to dilutions or patterns are rare in domestic breeds and were not found in Przewalski's horse. Higher frequencies of these alleles are only found in breeds that are selected for their expressed phenotypes (e.g., Kinsky horse, Lewitzer, Tinker). Nevertheless, our study produced strong evidence that molecular testing of the coat color is necessary for well-defined phenotyping to avoid unexpected colorations of offspring that can result in legal action.

To compare ocular structures of Quarter Horses homozygous for hereditary equine regional dermal asthenia (HERDA) with those of Quarter Horses not affected by HERDA (control horses) and to determine the frequency of new corneal ulcers for horses with and without HERDA during a 4-year period. Cohort study of ocular structures and retrospective case series of horses with and without HERDA. The cohort portion of the study involved 10 Quarter Horses with HERDA and 10 Quarter Horses without HERDA; the retrospective case series involved 28 horses with HERDA and 291 horses without HERDA. Ophthalmic examinations, Schirmer tear tests, tonometry, corneal pachymetry, histologic examinations, and scanning electron microscopy (SEM) were performed in cohorts of Quarter Horses with and without HERDA. Records were reviewed to determine the incidence of corneal ulcers in horses with and without HERDA during a 4-year period. Corneal thickness of horses with HERDA was significantly less than that of control horses, but tear production of horses with HERDA was significantly greater than that of control horses. Results of SEM revealed zones of disorganized, haphazardly arranged collagen fibrils in corneas of horses with HERDA that were not evident in corneas of control horses. The incidence of corneal ulcers was significantly greater for horses with HERDA than for horses without HERDA during the 4-year period. Alterations in corneal thickness, arrangement of collagen fibers, and incidence of corneal ulcers indicated that abnormalities in horses with HERDA were not limited to the skin.

Christensen, Janne Winther; Zharkikh, Tatjana; Ladevig, Jan

2008-01-01

Habituation to frightening stimuli plays an important role in horse training. To investigate the extent to which horses generalise between different visual objects, 2-year-old stallions were habituated to feeding from a container placed inside a test arena and assigned as TEST (n = 12) or REFERENCE...... horses (n = 12). In Experiment 1, TEST horses were habituated to six objects (ball, barrel, board, box, cone, cylinder) presented in sequence in a balanced order. The objects were of similar size but different colour. Each object was placed 0.5 m in front of the feed container, forcing the horses to pass...... the object to get to the food. TEST horses received as many 2 min exposures to each object as required to meet a habituation criterion. We recorded behavioural reactions to the object, latency to feed, total eating time, and heart rate (HR) during all exposures. There was no significant decrease in initial...

Metagenomics was used to characterize viral genomes in clinical specimens of horses with various organ-specific diseases of unknown aetiology. A novel parvovirus as well as a previously described hepacivirus closely related to human hepatitis C virus and equid herpesvirus 2 were identified in the cerebrospinal fluid of horses with neurological signs. Four co-infecting picobirnaviruses, including an unusual genome with fused RNA segments, and a divergent anellovirus were found in the plasma of two febrile horses. A novel cyclovirus genome was characterized from the nasal secretion of another febrile animal. Lastly, a small circular DNA genome with a Rep gene, from a virus we called kirkovirus, was identified in the liver and spleen of a horse with fatal idiopathic hepatopathy. This study expands the number of viruses found in horses, and characterizes their genomes to assist future epidemiological studies of their transmission and potential association with various equine diseases.

To obtain information on the types of Australian horses, how they are kept and their activities. An invitation to participate in an opt-in, internet-based survey was sent to 7000 people who had registered an email address to receive information from the Australian Horse Industry Council Inc. There were 3377 (48%) useable responses from owners of 26,548 horses. Most horses were kept on small properties (usually 2-8 ha) in paddocks in rural areas of Queensland, New South Wales and Victoria. Most horses were female or geldings and the most common of 54 different activities was breeding. Owners reported 19,291 horses were used in different activities and 6037 (23%) horses were not kept for any stated purpose or activity. Owners used an average of 1.95 horses in 2.9 different types of activities. The most common of the 43 breeds were Thoroughbred, Australian Stock Horse and Australian Quarter Horse. Only 1% of the total numbers of Thoroughbreds and Standardbreds in this survey were used in horse racing, indicating there is a demand for these breeds in non-racing activities. Microchip was the most favoured method of horse identification and 36% favoured compulsory registration of horses. Most respondents reported owning some other animal species. There is a wide variation in horse breeds used in different activities by Australian horse owners. There are regional differences in various management systems. There needs to be considerable improvement in the collection and recording of information to improve the validity and reliability of horse industry data. © 2016 Australian Veterinary Association.

Only little is known about behaviour and stress responses in horses with gastric ulceration, despite the high prevalence of this condition. Our objectives in the present study was to (i) describe the severity of gastric ulceration in horses, housed under relatively standardised conditions, and (ii......) to investigate whether horses with severe glandular gastric ulceration have increased baseline and response concentration of stress hormones and behave differently than control horses. We investigated stomachs of 96 horses at one stud, and compared an ulcer group (n = 30; with severe lesions in the glandular...... conclude that the prevalence of gastric ulcers was high, and our results suggest different factors affecting ulceration in the glandular versus the nonglandular region of the horse stomach. Obvious external signs (e.g. poor body condition) identifying ulcer horses were absent. Horses with severe glandular...

2013-01-01

The epidemiology of equine neorickettsiosis (EN) has been extensively studied but limited clinical and clinicopathological data are available concerning naturally infected horses. Factors predictive of survival will be identified in horses diagnosed with EN. Convenience sample of 44 horses with EN admitted to 2 referral institutions. A retrospective study was performed. A diagnosis of EN was based on the presence of positive blood or fecal PCR. The most common clinical signs included diarrhea (66%), fever (50%), anorexia (45%), depression (39%), colic (39%), and lameness (18%). The median duration of hospitalization was 6 days and 73% of horses survived to discharge. Laminitis was present in 36% of horses, 88% of which were affected in all 4 feet. Serum creatinine and urea nitrogen concentrations, as well as RBC count, blood hemoglobin concentration, hematocrit, band neutrophils, serum AST activity, serum CK activity, and anion gap, were significantly (P < .05) higher in nonsurvivors. Serum chloride and sodium, concentrations as well as duration of hospitalization were significantly lower in nonsurvivors. The results of forward stepwise logistic regression indicated that blood hemoglobin concentration on admission and antimicrobial treatment with oxytetracycline were independent factors associated with survival. Severity of colitis as reflected by electrolyte loss, hemoconcentration, and prerenal azotemia were predictors of survival in horses diagnosed with EN. Treatment with oxytetracycline was associated with increased survival. Copyright © 2013 by the American College of Veterinary Internal Medicine.

Plasticity effect of rider-horse interaction on genetic evaluations for Show Jumping discipline in sport horses.

Bartolomé, E; Menéndez-Buxadera, A; Molina, A; Valera, M

2018-04-01

To obtain a sport horse that excels in the highest levels of competition, breeders must take into account certain genetic and environmental factors that could influence the sport horse's performance, such as the rider-horse interaction (RHI). The main aim of this study was to describe this interaction in a genetic model by modelling it in relation to the horse's age. A total of 31,129 sport results from Spanish Sport Horses were used from a total of 1,101 animals evaluated, and these were grouped in three age levels and had been ridden by 606 different riders. Only riders who had ridden more than one horse (and vice-versa) were considered for the analyses. Five linear models with different random effects were analysed according to the covariates, the homogeneity/heterogeneity of the RHI and the relevant residual random effects. The model of best fit was then selected for the genetic evaluation of the animal. In general, models including the RHI effect (M2, M4 and M5) fitted better than the other models, and the best fit was obtained for M4 (with heterogeneous residual variance). The genetic variance increased constantly with age, whereas heritability showed a response on three intervals. This study revealed the varied evolution of the RHI with age, showing the different "plastic abilities" of this relationship. © 2018 Blackwell Verlag GmbH.

Non-market value of Estonian seminatural grasslands: a contingent valuation study. Eesti poolloodusliku rohumaa turuväline väärtus: tingliku hindamise uuring

Directory of Open Access Journals (Sweden)

2015-12-01

Full Text Available Seminatural grasslands i.e. the floodplain meadows, seashore meadows, wooded meadows, dry meadows, wooded pastures are the very traditional part of Estonian landscapes, which play an important role in the appearance of the landscape in general and also serve as an important habitat for many plant and animal species. In order to preserve the seminatural grasslands continuous annual mowing and/or pasturing is needed. This activity is not economically profitable and needs subsidizing. The authors of the work raise a hypothesis that the Estonian seminatural grasslands could be viewed as a valuable non-market environmental good for which a significant public demand exists. In order to find out the non-market value of the seminatural grasslands a contingent valuation study was carried out among the Estonian working-age population (size of the sample 1061 individuals. The average individual willingness to pay was 11.3 euros. During the study, the authors constructed the total demand function and discovered that the total annual demand for seminatural grasslands was 17.9 million euros.

The Management of Horses during Fireworks in New Zealand

Science.gov (United States)

Gronqvist, Gabriella; Rogers, Chris; Gee, Erica

2016-01-01

Simple Summary The negative effects of fireworks on companion animals have been reported, but little has been documented on the impact on horses. Horse anxiety was commonly associated with fireworks, and 26% of owners reported horse injuries as a result of fireworks. Many management strategies were seen as ineffective. The majority of horse owners were in favour of a ban on the sale of fireworks for private use. Abstract Within popular press there has been much coverage of the negative effects associated with firework and horses. The effect of fireworks has been documented in companion animals, yet no studies have investigated the negative effects, or otherwise, of fireworks on horses. This study aims to document horse responses and current management strategies to fireworks via an online survey. Of the total number of horses, 39% (1987/4765) were rated as “anxious”, 40% (1816/4765) “very anxious” and only 21% (965/4765) rated as “not anxious” around fireworks. Running (82%, 912/1107) was the most common behaviour reported, with no difference between property type (p > 0.05) or location (p > 0.05). Possibly as a consequence of the high frequency of running, 35% (384/1107) of respondents reported having horses break through fences in response to fireworks and a quarter (26%, 289/1099) reported that their horse(s) had received injuries associated with fireworks. The most common management strategy was moving their horse(s) to a paddock away from the fireworks (77%) and to stable/yard them (55%). However, approximately 30% reported these management strategies to be ineffective. Of the survey participants, 90% (996/1104) were against the sale of fireworks for private use. PMID:27005667

Serum amyloid A and haptoglobin concentrations in serum and peritoneal fluid of healthy horses and horses with acute abdominal pain

DEFF Research Database (Denmark)

Pihl, Tina Holberg; Andersen, Pia Haubro; Kjelgaard-Hansen, Mads

2013-01-01

BACKGROUND: Peritoneal fluid (PF) analysis is a valuable diagnostic tool in equine medicine. Markers such as serum amyloid A (SAA) and haptoglobin (Hp) could facilitate the diagnosis of inflammatory abdominal conditions. OBJECTIVES: The objectives were to (1) establish reference intervals (RI......) for SAA and Hp in serum and PF in healthy horses, (2) compare SAA and Hp concentrations between healthy horses and horses with colic, and (3) to assess the correlation between serum and PF concentrations. METHODS: Serum amyloid A and Hp concentrations were determined by automated assays in prospectively...... enrolled healthy reference horses and horses with colic. RIs were calculated, group concentrations were compared by Student's t-test, and Pearson's correlation for serum and PF concentrations were determined. RESULTS: In healthy horses (n = 62) the measurements for SAA were below the detection limit (0...

Generalization of a tactile stimulus in horses.

Science.gov (United States)

Dougherty, D M; Lewis, P

1993-05-01

Using horses, we investigated the control of operant behavior by a tactile stimulus (the training stimulus) and the generalization of behavior to six other similar test stimuli. In a stall, the experimenters mounted a response panel in the doorway. Located on this panel were a response lever and a grain dispenser. The experimenters secured a tactile-stimulus belt to the horse's back. The stimulus belt was constructed by mounting seven solenoids along a piece of burlap in a manner that allowed each to provide the delivery of a tactile stimulus, a repetitive light tapping, at different locations (spaced 10.0 cm apart) along the horse's back. Two preliminary steps were necessary before generalization testing: training a measurable response (lip pressing) and training on several reinforcement schedules in the presence of a training stimulus (tapping by one of the solenoids). We then gave each horse two generalization test sessions. Results indicated that the horses' behavior was effectively controlled by the training stimulus. Horses made the greatest number of responses to the training stimulus, and the tendency to respond to the other test stimuli diminished as the stimuli became farther away from the training stimulus. These findings are discussed in the context of behavioral principles and their relevance to the training of horses.

Recently, outbreaks associated with equine coronavirus (ECoV) have occurred in Japan and the United States. While ECoV is likely to be pathogenic to horses, it has not been shown that experimental inoculation of horses with ECoV produces clinical signs of disease. In this study, we inoculated three Japanese draft horses with an ECoV-positive diarrheic fecal sample to confirm infection after inoculation and to investigate the clinical course and virus shedding patterns of ECoV. Virus neutralization tests showed that all three horses became infected with ECoV. Two of the three horses developed clinical signs similar to those observed during ECoV outbreaks, including fever, anorexia, and gastrointestinal dysfunction. All horses excreted a large amount of virus into their feces for more than 9 days after inoculation regardless of the presence or absence of clinical signs, which suggests that feces are an important source of ECoV infection. ECoV was also detected in nasal swabs from all horses, suggesting that respiratory transmission of ECoV may occur. Both symptomatic horses developed viremia, while the asymptomatic horse did not. White blood cell counts and serum amyloid A concentrations changed relative to the clinical condition of the inoculated horses; these may be useful markers for monitoring the clinical status of horses infected with ECoV. This is the first report of induction of clinical signs of ECoV infection in horses by experimental inoculation. These clinical and virological findings should aid further investigation of the pathogenesis of ECoV.

Deuteron induced quasi-free scattering and reactions have been extensively investigated in the past few decades. This was done not only for nuclear structure and processes study but also for the important astrophysical implication (Trojan Horse Method, THM). In particular the width of the neutron momentum distribution in deuteron will be studied as a function of the transferred momentum. The same will be done for other nuclides of possible use as Trojan Horse particles. Trojan horse method applications will also be discussed because the momentum distribution of the spectator particle inside the Trojan horse nucleus is a necessary input for this method. The impact of the width (FWHM) variation on the extraction of the astrophysical S(E)-factor is discussed.

Severe polysaccharide storage myopathy in Belgian and Percheron draught horses.

Valentine, B A; Credille, K M; Lavoie, J P; Fatone, S; Guard, C; Cummings, J F; Cooper, B J

1997-05-01

A severe myopathy leading to death or euthanasia was identified in 4 Belgian and 4 Percheron draught horses age 2-21 years. Clinical signs ranged from overt weakness and muscle atrophy in 2 horses age 2 and 3 years, to recumbency with inability to rise in 6 horses age 4-21 years. In 5 horses there was mild to severe increases in muscle enzyme levels. Clinical diagnoses included equine motor neuron disease (2 horses), post anaesthetic myopathy (2 horses), exertional myopathy (2 horses), myopathy due to unknown (one horse), and equine protozoal myelitis (one horse). Characteristic histopathology of muscle from affected horses was the presence of excessive complex polysaccharide and/or glycogen, revealed by periodic acid-Schiff staining in all cases and by electron microscopy in one case. Evaluation of frozen section histochemistry performed on 2 cases indicated that affected fibres were Type 2 glycolytic fibres. Subsarcolemmal and intracytoplasmic vacuoles were most prominent in 3 horses age 2-4 years, and excessive glycogen, with little or no complex polysaccharide, was the primary compound stored in affected muscle in these young horses. Myopathic changes, including fibre size variation, fibre hypertrophy, internal nuclei, and interstitial fat infiltration, were most prominent in 5 horses age 6-21 years, and the accumulation of complex polysaccharide appeared to increase with age. Mild to moderate segmental myofibre necrosis was present in all cases.

2015-01-01

Hypoglycin A (HGA) in seeds of Acer spp. is suspected to cause seasonal pasture myopathy in North America and equine atypical myopathy (AM) in Europe, fatal diseases in horses on pasture. In previous studies, this suspicion was substantiated by the correlation of seed HGA content with the concentrations of toxic metabolites in urine and serum (MCPA-conjugates) of affected horses. However, seed sampling was conducted after rather than during an outbreak of the disease. The aim of this study was to further confirm the causality between HGA occurrence and disease outbreak by seed sampling during an outbreak and the determination of i) HGA in seeds and of ii) HGA and MCPA-conjugates in urine and serum of diseased horses. Furthermore, cograzing healthy horses, which were present on AM affected pastures, were also investigated. AM-pastures in Germany were visited to identify seeds of Acer pseudoplatanus and serum (n = 8) as well as urine (n = 6) from a total of 16 diseased horses were analyzed for amino acid composition by LC-ESI-MS/MS, with a special focus on the content of HGA. Additionally, the content of its toxic metabolite was measured in its conjugated form in body fluids (UPLC-MS/MS). The seeds contained 1.7–319.8 μg HGA/g seed. The content of HGA in serum of affected horses ranged from 387.8–8493.8 μg/L (controls horses on AM-pastures showed higher serum (108.8 ± 83.76 μg/L) and urine concentrations (26.9 ± 7.39 μg/L) compared to control horses, but lower concentrations compared to diseased horses. The range of MCPA-carnitine and creatinine concentrations found in diseased horses in serum and urine were 0.17–0.65 mmol/L (controls horses were higher compared to controls. Thus, the causal link between HGA intoxication and disease outbreak could be further substantiated, and the early detection of HGA in cograzing horses, which are clinically normal, might be a promising step in prophylaxis.

2010-02-24

At the Veterinary Microbiological Diagnostic Center, the Netherlands, the percentage of methicillin-resistant Staphylococcus aureus (MRSA) isolates found in equine clinical samples increased from 0% in 2002 to 37% in 2008. MRSA of spa-type t064, belonging to MLST ST8 and spa-types t011 and t2123, both belonging to the livestock-associated MLST ST398, predominated. During an outbreak of post-surgical MRSA infections in horses at a veterinary teaching hospital in 2006/2007, MRSA isolates of spa-type t2123 were cultured from 7 horses and 4/61 personnel which indicated zoonotic transmission. After intervention the outbreak stopped. However, another outbreak occurred in 2008, where 17 equine MRSA isolates of spa-type t011 (n=12), t2123 (n=4), and t064 (n=1) were found. This time, 16/170 personnel were positive for MRSA with spa-type t011 (n=11) and t2123 (n=5). Personnel in close contact with horses were more often MRSA-positive (15/106) than those without (1/64). Screening of horses upon admission showed that 9.3% were MRSA-positive predominantly with spa-type t011. Weekly cross-sectional sampling of all hospitalized horses for 5 weeks showed that 42% of the horses were MRSA-positive at least once, again predominantly with spa-type t011, which suggests that nosocomial transmission took place. Fifty-three percent of the environmental samples were MRSA-positive, including samples from students' and staff members' rooms, and all were spa-type t011. This indicates that humans contribute to spreading the organism. Culturing of samples employing high-salt pre-enrichment performed better than a comparable method without pre-enrichment. Our results show that nosocomial transmission occurs in equine clinics and suggests that personnel play a role in the transmission. Copyright 2009 Elsevier B.V. All rights reserved.

The Dominance of Indirect Taxes in Estonian State Budget

Directory of Open Access Journals (Sweden)

Olev Raju

2013-01-01

Full Text Available Recession has sharply erected the question of tax burden and the optimal proportion of different kinds of taxes among the incomes of the budget. Indirect taxes and consumption taxes, which proportion is different according to different methodologies, dominate in Estonian state budget. The buoyancy of a tax system based on taxes of that kind is especially weak during the recession. Difficulties concerning the incomes of budget have arisen the necessity for lifting taxes, which is possible as the tax burden is low now. But a sharp question of the optimal level of taxes is going to be raised. A formula for indirect tax optimum according to Ramsey taxes and Slutski decomposition has been proposed in the article.

Horse meat and its products can be considered as a food with a high nutritional value. However, due to cases of economically motivated food adulteration by the intentional addition of horse meat beef products in recent years, horse meat has become a controversial issue. Consumer confidence in meat products and the meat industry has diminished, although consumers consider the differences between the food content and the label as the major issue rather than the safety and nutritional characteristics of horse meat. The elaboration of meat products from horse meat (e.g. "cecina", dry-cured loin, salami, bressaola and pâté) is also an interesting alternative to other traditional meat products such as dry-cured pork hams, pork sausages and liver pâtés. In this review, the technological aspects, safety and storage stability of meat products elaborated from horse meat will be addressed by highlighting the nutritional and sensory aspects of these meat products. We aim to improve the existing knowledge about horse meat in the view of recent scandals. Copyright © 2017 Elsevier Ltd. All rights reserved.

Object recognition and generalisation during habituation in horses

Christensen, Janne Winther; Zharkikh, Tjatjana; Chovaux, Elodie

2011-01-01

The ability of horses to habituate to frightening stimuli greatly increases safety in the horse–human relationship. A recent experiment suggested, however, that habituation to frightening visual stimuli is relatively stimulus-specific in horses and that shape and colour are important factors...... for object generalisation (Christensen et al., 2008). In a series of experiments, we aimed to further explore the ability of horses (n = 30, 1 and 2-year-old mares) to recognise and generalise between objects during habituation. TEST horses (n = 15) were habituated to a complex object, composed of five...... simple objects of varying shape and colour, whereas CONTROL horses (n = 15) were habituated to the test arena, but not to the complex object. In the first experiment, we investigated whether TEST horses subsequently reacted less to i) simple objects that were previously part of the complex object (i...

Various horse populations in the Americas have an origin in Spain; they are remnants of the first livestock introduced to the continent early in the colonial period (16th and 17th centuries). We evaluated genetic variability within the Venezuelan Criollo horse and its relationship with other horse breeds. We observed high levels of genetic diversity within the Criollo breed. Significant population differentiation was observed between all South American breeds. The Venezuelan Criollo horse showed high levels of genetic diversity, and from a conservation standpoint, there is no immediate danger of losing variation unless there is a large drop in population size.

Leisure riding horses: research topics versus the needs of stakeholders.

Science.gov (United States)

Janczarek, Iwona; Wilk, Izabela

Horses intended for leisure riding do not undergo any selection and most often retired sports horses or defective horses are chosen, as a low selling price determines their purchase by a leisure riding center. Unfortunately, horses bought at low prices usually have low utility value, are difficult to handle, require a special or individual approach and do not provide satisfaction in riding. However, neither modern horse breeding nor scientific research address the need to breed horses for leisure activities. There is no clear definition of a model leisure horse and criteria or information for its selection are not readily available in scientific publications. A wide spectrum of research methods may be used to evaluate various performance traits in horses intended for leisure activities. The fact that the population of recreational horses and their riders outnumber sporting horses should attract the special attention of scientific research. Their utility traits need to be determined with modern technology and methods in the same way they are for sporting horses. Such a system of evaluation would be very helpful for riders. © 2017 Japanese Society of Animal Science.

To study the long-term mental health consequences of the 1986 Chernobyl nuclear accident among cleanup workers from Estonia. In 2010, 614 Estonian Chernobyl cleanup workers and 706 geographically and age-matched population-based controls completed a mail survey that included self-rated health, the Posttraumatic Stress Disorder Checklist (PCL), alcohol symptoms (AUDIT), and scales measuring depressive, anxiety, agoraphobia, fatigue, insomnia, and somatization symptoms. Respondents were dichotomized into high (top quartile) and low symptom groups on each measure. Logistic regression analysis detected significant differences between cleanup workers and controls on all measures even after adjustment for ethnicity, education, marital status, and employment status. The strongest difference was found for somatization, with cleanup workers being three times more likely than controls to score in the top quartile (OR = 3.28, 95% CI 2.39-4.52), whereas for alcohol problems the difference was half as large (OR = 1.52, 95% CI 1.16-1.99). Among cleanup workers, arrival at Chernobyl in 1986 (vs. later) was associated with sleep problems, somatization, and symptoms of agoraphobia. The toll of cleanup work was evident 24 years after the Chernobyl accident among Estonian cleanup workers indicating the need for focused mental health interventions.

The Eneolithic Botai culture of the Central Asian steppes provides the earliest archaeological evidence for horse husbandry, ~5500 years ago, but the exact nature of early horse domestication remains controversial. We generated 42 ancient-horse genomes, including 20 from Botai. Compared to 46 published ancient- and modern-horse genomes, our data indicate that Przewalski's horses are the feral descendants of horses herded at Botai and not truly wild horses. All domestic horses dated from ~4000 years ago to present only show ~2.7% of Botai-related ancestry. This indicates that a massive genomic turnover underpins the expansion of the horse stock that gave rise to modern domesticates, which coincides with large-scale human population expansions during the Early Bronze Age.

Investigating attentional processes in depressive-like domestic horses (Equus caballus).

Science.gov (United States)

Rochais, C; Henry, S; Fureix, C; Hausberger, M

2016-03-01

Some captive/domestic animals respond to confinement by becoming inactive and unresponsive to external stimuli. Human inactivity is one of the behavioural markers of clinical depression, a mental disorder diagnosed by the co-occurrence of symptoms including deficit in selective attention. Some riding horses display 'withdrawn' states of inactivity and low responsiveness to stimuli that resemble the reduced engagement with their environment of some depressed patients. We hypothesized that 'withdrawn' horses experience a depressive-like state and evaluated their level of attention by confronting them with auditory stimuli. Five novel auditory stimuli were broadcasted to 27 horses, including 12 'withdrawn' horses, for 5 days. The horses' reactions and durations of attention were recorded. Non-withdrawn horses reacted more and their attention lasted longer than that of withdrawn horses on the first day, but their durations of attention decreased over days, but those of withdrawn horses remained stable. These results suggest that the withdrawn horses' selective attention is altered, adding to already evidenced common features between this horses' state and human depression. Copyright © 2016.

Identifying anti-Toxocara IgG antibodies in horses of Mexico

Directory of Open Access Journals (Sweden)

R. Heredia

Full Text Available ABSTRACT Both the presence of owned dogs and stray dogs allows the spread of Toxocara, a parasite whose eggs can be found in soil, water and food. Animals, including horses, serve as definitive and paratenic hosts. In México, where consumption of horse meat is common, Toxocara is a zoonotic parasite. The aim of this study was to identify the presence of anti-Toxocara antibodies in work horses and horses intended for human consumption by ELISA. ELISA was chosen for analysis as paratenic hosts do not shed Toxocara eggs in their feces. Blood samples were collected from a total of 188 horses, 94 of which were work horses and 94 horses from the slaughter house. Samples were analyzed by ELISA, and the general equine seroprevalence was found to be 44.6% (n = 188. Adult horses for slaughter had a 61.7% greater presence of anti-Toxocara antibodies (p = 0.006. Toxocara IgG antibodies were found in horses, confirming that horses are paratenic hosts and possible sources of infection for other animals and people.

In this study, we aimed to investigate the effects of an unstable group structure, caused by weekly regroupings, on behaviour and frequency of injuries in young horses. Forty...... after each regrouping (2 × 20 min/group/day). Injuries were scored by the end of the experimental period. The level of aggression shown by horses in Unstable groups immediately after regrouping was not affected by week (F5,35 = 0.42, P = 0.83), indicating that horses neither habituated, nor sensitized...... injuries were registered and there was no treatment effect (U = 184; P = 0.11). We conclude that the behaviour of young horses is affected by group management, and that horses appear not to adapt to weekly regroupings....

Full Text Available Genetics is important for breeding and selection of horses but there is a lack of well-established horse-related browsers or databases. In order to better understand horses, more variants and other integrated information are needed. Thus, we construct a horse genomic variants database including expression and other information. Horse Single Nucleotide Polymorphism and Expression Database (HSDB (http://snugenome2.snu.ac.kr/HSDB provides the number of unexplored genomic variants still remaining to be identified in the horse genome including rare variants by using population genome sequences of eighteen horses and RNA-seq of four horses. The identified single nucleotide polymorphisms (SNPs were confirmed by comparing them with SNP chip data and variants of RNA-seq, which showed a concordance level of 99.02% and 96.6%, respectively. Moreover, the database provides the genomic variants with their corresponding transcriptional profiles from the same individuals to help understand the functional aspects of these variants. The database will contribute to genetic improvement and breeding strategies of Thoroughbreds.

Jacobs, Carrie C; Levine, David G; Richardson, Dean W

2017-02-01

To describe the outcome, clinical findings, and complications associated with the use of the locking compression plate (LCP) for various types of ulnar fractures in horses. Retrospective case series. Client owned horses (n = 18). Medical records, radiographs, and follow-up for horses having an ulnar fracture repaired using at least 1 LCP were reviewed. Fifteen of 18 horses had fractures of the ulna only, and 3 horses had fractures of the ulna and proximal radius. All 18 horses were discharged from the hospital. Complications occurred in 5 horses; incisional infection (n = 4, 22%), implant-associated infection (n = 2, 11%), and colic (n = 1, 6%). Follow-up was available for all horses at a range of 13-120 months and 15 horses (83%) were sound for their intended purpose and 3 horses (17%) were euthanatized. One horse was euthanatized for complications associated with original injury and surgery. The LCP is a viable method of internal fixation for various types of ulnar fractures, with most horses in this series returning to soundness. © 2017 The American College of Veterinary Surgeons.

Welfare issues of horses: an overview and practical recommendations

Elisabetta Canali

2010-01-01

Full Text Available The largest proportion of the world’s horses are still used for work in agriculture and traction, however in the western countries they are increasingly kept for recreational and social purposes, breeding, sport and competition. It is often assumed that horses enjoys better farming conditions than other species, yet they have specific needs which should be fulfilled in order to have a proper welfare. This paper will review the main welfare issues of horses and the following aspects will be considered: nutrition, housing and management, clinical problems, behaviour problems, training and riding, transportation, measuring welfare. Horses are social animals that live in groups in close contact with conspecifics. They spend most of their waking hours moving at walk, grazing and eating grass. Some of the constraints imposed on horses during the last centuries conflict to their naturally evolved behaviour. Effective and humane handling of horses positively affects many important aspects like the safety of man, the performance level and the welfare of horses. It is an essential condition for keeping horses that handlers, riders, trainers, farriers and veterinarians have proper knowledge of the behaviour of the horse in order to fulfil their natural needs and guarantee their welfare.

The Management of Horses during Fireworks in New Zealand

2016-03-01

Full Text Available Within popular press there has been much coverage of the negative effects associated with firework and horses. The effect of fireworks has been documented in companion animals, yet no studies have investigated the negative effects, or otherwise, of fireworks on horses. This study aims to document horse responses and current management strategies to fireworks via an online survey. Of the total number of horses, 39% (1987/4765 were rated as “anxious”, 40% (1816/4765 “very anxious” and only 21% (965/4765 rated as “not anxious” around fireworks. Running (82%, 912/1107 was the most common behaviour reported, with no difference between property type (p > 0.05 or location (p > 0.05. Possibly as a consequence of the high frequency of running, 35% (384/1107 of respondents reported having horses break through fences in response to fireworks and a quarter (26%, 289/1099 reported that their horse(s had received injuries associated with fireworks. The most common management strategy was moving their horse(s to a paddock away from the fireworks (77% and to stable/yard them (55%. However, approximately 30% reported these management strategies to be ineffective. Of the survey participants, 90% (996/1104 were against the sale of fireworks for private use.

Where Do Dead Books Go? The Problem of the Soviet Canon Today, on the Example of Johannes Becher's Work in Estonian

Directory of Open Access Journals (Sweden)

Katre Talviste

2013-06-01

Full Text Available The article describes the conception and editing process of an anthology of Johannes Becher’s poems (Unistades täiusest, 1962 in Estonian, and discusses its status in the Soviet and contemporary literary canon. The work on the Becher anthology was led by an already outstanding literary scholar Nigol Andresen and a young poet and translator Ain Kaalep, who later became one of the most prolific and wellknown poetry translators in Estonia. An important part was also played by another poet-translator, August Sang, who already had achieved such a standing in the Estonian literary field. Several other translators contributed to the anthology, making it a common project for intellectuals otherwise very differently positioned vis-à-vis the Soviet political authorities and cultural agendas. Becher’s work was strongly promoted by these instances, but his poetry was also read with genuine enthusiasm by the main contributors to the anthology (whose own poetry has certain parallels to some aspects of Becher’s, as well as the general public, at that time. After the fall of the Soviet regime it has been forgotten, mostly for the same contextual reasons that once granted its success. The case of his poetry in Estonian explores the question of this new invisibility of now politically irrelevant, but still voluminous and aesthetically intriguing literary works in the post-Soviet canon.

2017-03-01

Assessment of left ventricular (LV) function by tissue Doppler imaging (TDI) is not well established in horses with heart disease. To describe the use of pulsed-wave (PW) TDI for the assessment of LV function, establish reference intervals, investigate effects of mitral regurgitation (MR), aortic regurgitation (AR), and primary myocardial disease (MD), and provide proof of concept for the use of PW TDI in Warmblood horses with heart disease. Thirty healthy horses, 38 horses with MR, 25 with AR, 8 with MD. Echocardiograms were retrospectively analyzed. Reference intervals were calculated. PW TDI indices of healthy horses and horses with MR, AR, and MD were compared by one-way ANOVA and Dunnett's test. A complete set of PW TDI variables could be obtained in 94 of 101 horses. Variables corresponding to isovolumic intervals were most difficult to measure. Valvular regurgitation influenced variables describing isovolumic contraction and ejection. Horses with MD had significantly shortened ET m (-118.5 [-154.1 to -82.9] ms; mean difference [95% CI of difference of means]), increased PEP m /ET m (0.11 [0.05 to 0.17]), prolonged IMP m (0.28 [0.18 to 0.37]), increased S 1 (8.9 [5.2 to 12.6] cm/s), and decreased E 1 (-2.6 [-4.7 to -0.5] cm/s), E m (-14.2 [-19.9 to -8.5] cm/s), and E m /A m ratio (-1.6 [-2.6 to -0.6]). Pulsed-wave TDI might be useful for detection of LV dysfunction in horses with primary MD. The clinical value of TDI in horses with MR and AR remains uncertain. Copyright © 2017 The Authors.

DNA polymorphism of Arabian, Thoroughbred and Anglo-Arab horses in Morocco. Application to identification and parentage verification of individual horses

International Nuclear Information System (INIS)

Ouragh, L.

2005-01-01

New techniques of molecular biology used in analysing DNA polymorphism give access to the whole genetic variability of a given individual, while traditional blood typing (red cell typing and biochemical polymorphisms) gives access only to the transcribed Fraction, which is then translated to protein. In addition, this fraction represents only a tiny part (5 to 10%) of the genome's coding fraction. One of the newer testing methods in identifying horses is a DNA-based test using microsatellite marker analysis. The objective of this work was to evaluate the efficacy of this new technology in the identification and parentage verification of Arabian, Thoroughbred and Anglo-Arab horses in Morocco. The Anglo-Arab horse is a crossbreed between Arabian and Thoroughbred. Three samples from the three breeds were analysed for 12 microsatellites (HMS2, HMS3, HMS6, HMS7, HTG4, HTG6, HTG7, AHT4, AHTS, VHL20, HTGlO and ASB2). Blood samples were gathered from a total of 1541 horses: 804 Arabians, 559 Thoroughbreds and 178 Anglo-Arabs. Allelic frequencies of the 12 loci studied were calculated in the three groups. The results allowed the determination of intra-population genetic parameters: heterozygosity ratio (h), probability of identification (P i ) and probability of exclusion (P e ). Based on mean heterozygosity values, variability was relatively lower in Thoroughbred horse (0.7036), while it was almost the same in Arabian and Anglo-Arab horses (respectively 0.7217 and 0.7232). Probabilities of exclusion obtained with the 12 systems were greater than 99.9% for the three populations studied, and probabilities of identification of individual horses were 15.4 x 10 -12 , 3 .5 x 10 -12 and 3.2 x 10 -12 in the Thoroughbred, Arabian and Anglo-Arab breeds, respectively. These results indicate that the test using microsatellite marker analysis constitutes a highly efficient and reliable alternative for the identification and parentage verification of individual horses and so it is a

This study aims at the comparison of the actual feeding of horses with the recommendations from the literature, and it studies the effects of feeding and exercise on several blood metabolic parameters before and after exercise. Blood samples were collected from 25 horses during one-star eventing competitions and evaluated for blood glucose, insulin, lactate, free fatty acids and triglyceride levels. Questionnaires on the feeding practices of the horses were evaluated. The questionnaires revealed that during training, and on tournament days, horses received on average 4.3 kg of concentrate per day (min. 1.54 kg, max. 8 kg). The statistical analysis showed no significant effect of the amount of concentrate fed before exercise on the measured blood values. Oil was supplied as a supplementary energy source to 30% of the horses, but most of them only received very small quantities (0.02-0.4 l/day). Five horses (20%) had no access to salt supplements at all, and eleven horses (45%) had no access to salt on tournament days. Fifteen horses (60%) were supplied with mineral feed. Twenty-one horses (84%) had daily access to pasture during the training period. During competition, 55% of the horses received roughage ad libitum, compared with 37% during training. The majority of the horses received less roughage on days before the cross-country competition. It could not be ascertained whether feeding a large amounts of roughage had a beneficial effect on performance, because only a few horses in this study were fed with very restrictive roughage. Feeding of most of the horses was in agreement with the recommendations from the literature, except the need for sodium and chloride. The sodium and chloride need for sport horses may be overestimated in literature and needs to be re-evaluated. © 2012 Blackwell Verlag GmbH.

Renal replacement therapy (RRT) has been implemented extensively in people to facilitate recovery from acute renal failure (ARF). RRT has not been explored in horses, but might provide a further treatment option in horses with ARF. To investigate efficacy and safety of RRT in horses. Five healthy adult horses. A prospective study was performed on horses restrained in stocks and intravenously connected to a commercial RRT machine to allow continuous venovenous hemodiafiltration to be performed for 6 hours. The RRT machine was set at the following flow rates: blood flow rate 250 mL/min; dialysate rate 3,000 mL/h; prefilter replacement pump 3,000 mL/h; and postfilter replacement pump rate 2,000 mL/h. Balanced electrolyte solution was used as dialysate and replacement fluid. Heart rate, respiratory rate, body temperature, direct arterial blood pressure, urine output, and various clinicopathologic parameters were measured over the study period. Renal replacement therapy was successfully performed in horses, resulting in a mean creatinine clearance of 0.127 mL/kg/min (68.9 mL/min) and urea reduction ratio of 24%. No adverse effects were detected although a significant decrease in rectal temperature was observed (P ≤ .007). A significant increase in serum phosphorus (P ≤ .001) and decrease in BUN (P replacement therapy can safely and effectively be used in adult horses.

Baker, Shannon J; Johnson, Philip J; David, Andrew; Cook, Cristi Reeves

2004-06-15

Chronic gastroesophageal reflux disease was diagnosed in a 22-year-old female Tennessee Walking Horse that had signs of bruxism and ptyalism. Esophageal ulceration was detected via endoscopy. Compared with the damage to the proximal portions of the esophagus, the severity of the ulceration increased toward the gastroesophageal junction. Esophageal ulceration attributable to chronic gastric acid reflux is usually secondary to pyloric outflow obstruction in horses. In the horse of this report, there was no evidence of either a chronic pyloric or duodenal obstruction that could have resulted in esophageal ulceration. Esophageal ulceration in this horse was attributed to gastroesophageal reflux disease, a common condition in humans in which the underlying abnormality is functional incompetence of the gastroesophageal junction. Treatment is directed at decreasing gastric acidity and protecting the ulcerated mucosa. In the horse of this report, treatment was unsuccessful and the horse was euthanatized; a physical cause of gastroesophageal reflux disease was not identified during an extensive postmortem examination.

Horses are phylogenetically distant from primates, but considerable behavioral links exist between the two. The sociality of horses, characterized by group stability, is similar to that of primates, but different from that of many other ungulates. Although horses and primates are good models for exploring the evolution of societies in human and non-human animals, fewer studies have been conducted on the social system of horses than primates. Here, we investigated the social system of feral horses, particularly the determinant factors of single-male/multi-male group dichotomy, in light of hypotheses derived from studies of primate societies. Socioecological data from 26 groups comprising 208 feral horses on Serra D'Arga, northern Portugal suggest that these primate-based hypotheses cannot adequately explain the social system of horses. In view of the sympatric existence of multi- and single-male groups, and the frequent intergroup transfers and promiscuous mating of females with males of different groups, male-female relationships of horses appear to differ from those of polygynous primates.

Analysis of breed effects on semen traits in light horse, warmblood, and draught horse breeds.

Gottschalk, Maren; Sieme, Harald; Martinsson, Gunilla; Distl, Ottmar

2016-05-01

In the present study, systematic effects on semen quality traits were investigated in 381 stallions representing 22 breeds. All stallions were used for AI either at the Lower Saxon National Stud Celle or the North Rhine-Westphalian National Stud Warendorf. A total of 71,078 fresh semen reports of the years 2001 to 2014 were edited for analysis of gel-free volume, sperm concentration, total number of sperm, progressive motility, and total number of progressively motile sperm. Breed differences were studied for warmblood and light horse breeds of both national studs (model I) and for warmblood breeds and the draught horse breed Rhenish German Coldblood from the North Rhine-Westphalian National stud (model II) using mixed model procedures. The fixed effects of age class, year, and month of semen collection had significant influences on all semen traits in both analyses. A significant influence of the horse breed was found for all semen traits but gel-free volume in both statistical models. Comparing warmblood and light horse stallions of both national studs, we observed highest sperm concentrations, total numbers of sperm, and total numbers of progressively motile sperm in Anglo-Arabian stallions. The draught horse breed Rhenish German Coldblood had the highest least squares means for gel-free volume, whereas all other investigated semen traits were significantly lower in this breed compared to the warmblood stallions under study. The variance components among stallions within breeds were significant for all semen traits and accounted for 40% to 59% of the total variance. The between-breed-variance among stallions was not significant underlining the similar size of the random stallion effect in each of the horse breeds analyzed here. In conclusion, breed and stallion are accounting for a significant proportion of the variation in semen quality. Copyright © 2016 Elsevier Inc. All rights reserved.

Characterisation of the horse transcriptome from immunologically active tissues

2014-05-01

Full Text Available The immune system of the horse has not been well studied, despite the fact that the horse displays several features such as sensitivity to bacterial lipopolysaccharide that make them in many ways a more suitable model of some human disorders than the current rodent models. The difficulty of working with large animal models has however limited characterisation of gene expression in the horse immune system with current annotations for the equine genome restricted to predictions from other mammals and the few described horse proteins. This paper outlines sequencing of 184 million transcriptome short reads from immunologically active tissues of three horses including the genome reference “Twilight”. In a comparison with the Ensembl horse genome annotation, we found 8,763 potentially novel isoforms.

Vascular dysfunction, most commonly due to endothelial dysfunction, is associated with cardiovascular risk in people with metabolic syndrome and Cushing's syndrome. We tested the hypothesis that horses with EL have vascular, specifically endothelial, dysfunction. Healthy horses (n = 6 and horses with EL (n = 6 destined for euthanasia were recruited. We studied vessels from the hooves (laminar artery, laminar vein and the facial skin (facial skin arteries by small vessel wire myography. The response to vasoconstrictors phenylephrine (10-9-10-5M and 5-hydroxytryptamine (5HT; 10-9-10-5M and the vasodilator acetylcholine (10-9-10-5M was determined. In comparison with healthy controls, acetylcholine-induced relaxation was dramatically reduced in all intact vessels from horses with EL (% relaxation of healthy laminar arteries 323.5 ± 94.1% v EL 90.8 ± 4.4%, P = 0.01, laminar veins 129.4 ± 14.8% v EL 71.2 ± 4.1%, P = 0.005 and facial skin arteries 182.0 ± 40.7% v EL 91.4 ± 4.5%, P = 0.01. In addition, contractile responses to phenylephrine and 5HT were increased in intact laminar veins from horses with EL compared with healthy horses; these differences were endothelium-independent. Sensitivity to phenylephrine was reduced in intact laminar arteries (P = 0.006 and veins (P = 0.009 from horses with EL. Horses with EL exhibit significant vascular dysfunction in laminar vessels and in facial skin arteries. The systemic nature of the abnormalities suggest this dysfunction is associated with the underlying endocrinopathy and not local changes to the hoof.

Full Text Available Abstract Background The Irish Horse Industry expanded during the Celtic Tiger boom years, then contracted in the current economic recession. High value horses were traditionally controlled through sale at public auction, private sales and sales to dealers; these are now also being reduced by decreases in production (> 40%, and increases in retirement, re-homing, euthanasia and disposal through Category 2 plants and abattoirs. The absence or banning of horse abattoirs has been shown to have very significant welfare social and economic consequences in the USA. This study described the currently available data on the demographics of unwanted horses in Ireland from 2005 to 2010. Results The majority of horses euthanised by practicing veterinarians are destroyed on medical grounds but the number euthanised at the request of welfare groups and the state, as well as welfare related calls and the number of horses involved in these calls and subsequent visits is increasing reflecting the increasing involvement of the veterinary profession in equine welfare. Welfare groups have limited resources and do not have a tradition of recording data, but they too have reported increasing calls, visits and numbers of horses per visit. Welfare groups provide significant service to equine welfare and the community. Local Authorities report similar trends. Over 300 horses were found dead or required immediate or subsequent euthanasia following welfare group and local authority visits in 2010, which is of national concern. The majority of local authority interfaces with unwanted horses are with urban (60% rather than rural (40% horses. Mortality figures are poor indicators of non-fatal neglect. More horses were admitted into the care of local authorities than welfare groups, reflecting significant state and taxpayer investment in the control of low value horses. Category 2 plants and abattoirs represent a significant state investment in licensing and control in the

The objective of the study was to assess the pharmacokinetics of terbinafine administered orally to horses and Greyhound dogs. A secondary objective was to assess terbinafine metabolites. Six healthy horses and six healthy Greyhound dogs were included in the pharmacokinetic data. The targeted dose of terbinafine was 20 and 30 mg/kg for horses and dogs, respectively. Blood was collected at predetermined intervals for the quantification of terbinafine concentrations with liquid chromatography and mass spectrometry. The half-life (geometric mean) was 8.1 and 8.6 h for horses and Greyhounds, respectively. The mean maximum plasma concentration was 0.31 and 4.01 μg/mL for horses and Greyhounds, respectively. The area under the curve (to infinity) was 1.793 h·μg/mL for horses and 17.253 h·μg/mL for Greyhounds. Adverse effects observed in one study horse included pawing at the ground, curling lips, head shaking, anxiety and circling, but these resolved spontaneously within 30 min of onset. No adverse effects were noted in the dogs. Ions consistent with carboxyterbinafine, n-desmethylterbinafine, hydroxyterbinafine and desmethylhydroxyterbinafine were identified in horse and Greyhound plasma after terbinafine administration. Further studies are needed assessing the safety and efficacy of terbinafine in horses and dogs. © 2010 Blackwell Publishing Ltd.

Medical records of 28 horses with osteomyelitis of the calcaneus were reviewed to evaluate signalment, history, diagnostic and treatment methods, outcome, and long-term follow-up information. Trauma was the most commonly reported cause (24). Physical examination revealed lameness in 27 horses, and 22 (79%) had a wound or draining tract over the plantar aspect of the calcaneus. Radiography of all horses was done prior to the initiation of treatment, and follow-up radiography was done on 20 horses. The most common radiographic findings were soft tissue swelling (25), bony lysis of the calcaneus (17), bone fragments or sequestra from the tuber calcis (13), and periosteal new bone production or bony lysis of the sustentaculum tali (5). Association could not be found between initial radiographic findings and eventual outcome of the case. Positive bacterial cultures were obtained from 13 horses. A wide variety of gram-positive, gram-negative, and anaerobic organisms were isolated. Fourteen of the 15 isolates, for which susceptibilities were reported, were susceptible to penicillin, gentamicin, or trimethoprim sulfamethoxazole. Twenty-six of the 28 horses diagnosed as having osteomyelitis of the calcaneus were treated; 16 horses were treated with surgical debridement in addition to antimicrobial treatment, and 10 horses were treated with antimicrobial agents, anti-inflammatory drugs, or supportive wound care. There was no significant difference in survival rate of horses treated surgically and those treated conservatively. Six horses that were treated were later euthanatized for problems associated with chronic osteomyelitis, and 2 horses died or were euthanatized for unrelated problems. Eighteen horses (64%) were alive at last follow-up

OBJECTIVE To purify and characterize equine vitamin D-binding protein (VDBP) from equine serum and to evaluate plasma concentrations of VDBP in healthy horses and horses with gastrointestinal injury or disease. ANIMALS 13 healthy laboratory animals (8 mice and 5 rabbits), 61 healthy horses, 12 horses with experimentally induced intestinal ischemia and reperfusion (IR), and 59 horses with acute gastrointestinal diseases. PROCEDURES VDBP was purified from serum of 2 healthy horses, and recombinant equine VDBP was obtained through a commercial service. Equine VDBP was characterized by mass spectrometry. Monoclonal and polyclonal antibodies were raised against equine VDBP, and a rocket immunoelectrophoresis assay for equine VDBP was established. Plasma samples from 61 healthy horses were used to establish working VDBP reference values for study purposes. Plasma VDBP concentrations were assessed at predetermined time points in horses with IR and in horses with naturally occurring gastrointestinal diseases. RESULTS The working reference range for plasma VDBP concentration in healthy horses was 531 to 1,382 mg/L. Plasma VDBP concentrations were significantly decreased after 1 hour of ischemia in horses with IR, compared with values prior to induction of ischemia, and were significantly lower in horses with naturally occurring gastrointestinal diseases with a colic duration of < 12 hours than in healthy horses. CONCLUSIONS AND CLINICAL RELEVANCE Plasma VDBP concentrations were significantly decreased in horses with acute gastrointestinal injury or disease. Further studies and the development of a clinically relevant assay are needed to establish the reliability of VDBP as a diagnostic and prognostic marker in horses.

Several studies have shown that a considerable proportion of horses are eliminated from endurance rides due to lameness and metabolic problems. Limited information is available on specific veterinary issues in endurance horses and there are no descriptive data on veterinary problems in a large population of endurance horses. The aim of this study was to describe veterinary problems occurring in endurance horses in England and Wales, the regions of the United Kingdom where endurance rides are organised and regulated by Endurance Great Britain (Endurance GB). A comprehensive online self-completed questionnaire was used for data collection (30th December 2015-29th February 2016) All members of Endurance GB who were the main rider of one or more endurance horses were eligible to participate. From the target population of 1209 horses, 190 questionnaires were completed by riders, resulting in a 15.7% response rate. The most common rider-reported veterinary problem was lameness, affecting 152/190 (80.0%) of endurance horses at some point during their careers and 101/190 (53.2%) of horses in the previous 12 months. Detailed information on the most recent episode of lameness was available for 147 horses. Seventy-six percent of these lameness episodes (112/147) had been initially identified by a veterinarian, but only 52% of these lameness episodes were investigated further by a veterinarian, despite the high proportion of horses affected by lameness and the proportion of horses with recurrent lameness episodes. The second most common veterinary problem was thoracolumbar region pain, followed by non-specific cough, skin disease and colic. Education of endurance riders may improve the number, quality and timing of veterinary investigations, especially for lameness and thoracolumbar region pain. Copyright © 2017 Elsevier B.V.

Full Text Available The topic of this article is the literary discourse of Young Estonia; its relations with other important Estonian literary discourses from the beginning of the 20th century, and its relations with colonial cultural discourse. First, I give an overview of the basic positions of the Young Estonians’ literary discourse, the main shapers of which were Friedebert Tuglas, Gustav Suits, later on Johannes Semper as well. Next, I present the basic principles of three Estonian literary discourses from the beginning of the 20th century, which were also important to the Young Estonians: nationalist-naturalistic (close-to-life; socialist/ class-based, and 20th century modernist. The Young Estonians began as nationalists and/or socialists. During the formation of Young Estonia’s discourse at the end of the first and beginning of the second decade of the 20th century, 20th century modernism began, which the Young Estonians regarded first and foremost with irony. The Young Estonians’ literary discourse is a mixture of aestheticism, decadence, symbolism, romanticism, and classicism. The point of departure for the Young Estonian approach to literature was eurocentrism. They took a superior and negative view of existing Estonian literature, which they regarded as having fallen drastically behind Europe. Since it was unable to build on its own foundation, it had to borrow from Europe. The discourse’s understandings of cultural values – theory, reading, knowledge, ready-made culture, derive from the centrality of the dynamic of borrowing. New culture could be created freely, without the support of previous local tradition; it was to be an elite culture, while the writer remained an individualist. Literature was to follow the principle of art for art’s sake; aesthetics and the form of the work of art were basic criteria. The formal ideals of the work of art were classicist: unity, integrity (wholeness, harmony, order, logic, etc. Thirdly, I outline the

Identification of copy number variants in horses

Copy number variants (CNVs) represent a substantial source of genetic variation in mammals. However, the occurrence of CNVs in horses and their subsequent impact on phenotypic variation is unknown. We performed a study to identify CNVs in 16 horses representing 15 distinct breeds (Equus caballus) and an individual gray donkey (Equus asinus) using a whole-exome tiling array and the array comparative genomic hybridization methodology. We identified 2368 CNVs ranging in size from 197 bp to 3.5 Mb. Merging identical CNVs from each animal yielded 775 CNV regions (CNVRs), involving 1707 protein- and RNA-coding genes. The number of CNVs per animal ranged from 55 to 347, with median and mean sizes of CNVs of 5.3 kb and 99.4 kb, respectively. Approximately 6% of the genes investigated were affected by a CNV. Biological process enrichment analysis indicated CNVs primarily affected genes involved in sensory perception, signal transduction, and metabolism. CNVs also were identified in genes regulating blood group antigens, coat color, fecundity, lactation, keratin formation, neuronal homeostasis, and height in other species. Collectively, these data are the first report of copy number variation in horses and suggest that CNVs are common in the horse genome and may modulate biological processes underlying different traits observed among horses and horse breeds.

Neutrophil and macrophage apoptosis in bronchoalveolar lavage fluid from healthy horses and horses with recurrent airway obstruction (RAO)

Science.gov (United States)

2014-01-01

Background Dysregulation of apoptosis has been implicated in a range of diseases including tumors, neurodegenerative and autoimmine diseases, as well as allergic asthma and chronic obstructive pulmonary disease (COPD) in humans. Although it has a different pathophysiology, delayed apoptosis of various inflammatory cells may play a pivotal role in the development of recurrent airway obstruction (RAO) in horses. Reduction of inflammatory cell apoptosis or a dysregulation of this process could lead to chronic inflammation and tissue injury. Therefore, the aim of this study was to investigate the rate of apoptosis and necrosis of neutrophils and macrophages in bronchoalveolar lavage fluid obtained from seven horses suffering from RAO (study group) and seven control horses. Results We demonstrated that neutrophil/macrophage apoptosis is altered in RAO-affected horses compared with the control group in the BAL fluid. We found a significant difference between the median percentage of early and late apoptosis of neutrophils between the study and control group of horses. Moreover, we found a positive correlation between the rate of apoptosis and the median percentage of macrophages in RAO-affected horses. Conclusion The findings suggest that apoptosis dysregulation may play a significant role in the pathogenesis of RAO. However, further studies are needed to clarify the role of altered apoptosis in the course of equine recurrent airway obstruction. PMID:24460911

Scintigraphy (bone scan) is being used approximately since 1980 in the horse under general anaesthesia. With the construction of custom-made overhead gantries for gamma-cameras scintigraphy found widespread entry in big equine referral hospitals for bone-scanning of the standing horse. Indications for the use of a bone scan in the horse are inflammatory alterations in the locomotor apparatus. It is primarily used for diagnosis of lameness of unknown origin, suspect of stress fracture or hairline fracture and for horses with bad riding comfort with suspected painful lesions in the spine.

Theory of the Trojan-Horse method

International Nuclear Information System (INIS)

Typel, S.; Baur, G.

2003-01-01

The Trojan-Horse method is an indirect approach to determine the energy dependence of S factors of astrophysically relevant two-body reactions. This is accomplished by studying closely related three-body reactions under quasi-free scattering conditions. The basic theory of the Trojan-Horse method is developed starting from a post-form distorted wave Born approximation of the T-matrix element. In the surface approximation the cross-section of the three-body reaction can be related to the S-matrix elements of the two-body reaction. The essential feature of the Trojan-Horse method is the effective suppression of the Coulomb barrier at low energies for the astrophysical reaction leading to finite cross-sections at the threshold of the two-body reaction. In a modified plane wave approximation the relation between the two- and three-body cross-sections becomes very transparent. The appearing Trojan-Horse integrals are studied in detail

Unlike in Warmblood horses, aortic rupture is quite common in Friesian horses, in which a hereditary trait is suspected. The aortic connective tissue in affected Friesians shows histological changes such as medial necrosis, elastic fibre fragmentation, mucoid material accumulation and fibrosis with aberrant collagen morphology. However, ultrastructural examination of the collagen fibres of the mid-thoracic aorta has been inconclusive in further elucidating the pathogenesis of the disease. To assess several extracellular matrix (ECM) components biochemically in order to explore a possible underlying breed-related systemic ECM defect in Friesians with aortic rupture. Cadaver study. Tissues from affected Friesians (n = 18), unaffected Friesians (n = 10) and Warmblood horses (n = 30) were compared. Samples were taken from the thoracic aorta at the level of the rupture site, from two locations caudal to the rupture and from the deep digital flexor tendon. Total collagen content, post-translational modifications of collagen formation including lysine hydroxylation, and hydroxylysylpyridinoline (HP), lysylpyridinoline (LP) and pyrrole cross-links were analysed. Additionally, elastin cross-links, glycosaminoglycan content and matrix metalloproteinase (MMP) activity were assessed. Significantly increased MMP activity and increased LP and HP cross-linking, lysine hydroxylation and elastin cross-linking were found at the site of rupture in affected Friesians. These changes may reflect processes involved in healing and aneurysm formation. Unaffected Friesians had less lysine hydroxylation and pyrrole cross-linking within the tendons compared with Warmblood horses. No differences in the matrix of the aorta were found between normal Warmbloods and Friesian horses. Small sample size. The differences in collagen parameters in tendon tissue may reflect differences in connective tissue metabolism between Friesians and Warmblood horses. © 2017 EVJ Ltd.

Hypoglycin A Content in Blood and Urine Discriminates Horses with Atypical Myopathy from Clinically Normal Horses Grazing on the Same Pasture.

Directory of Open Access Journals (Sweden)

M Bochnia

Full Text Available Hypoglycin A (HGA in seeds of Acer spp. is suspected to cause seasonal pasture myopathy in North America and equine atypical myopathy (AM in Europe, fatal diseases in horses on pasture. In previous studies, this suspicion was substantiated by the correlation of seed HGA content with the concentrations of toxic metabolites in urine and serum (MCPA-conjugates of affected horses. However, seed sampling was conducted after rather than during an outbreak of the disease. The aim of this study was to further confirm the causality between HGA occurrence and disease outbreak by seed sampling during an outbreak and the determination of i HGA in seeds and of ii HGA and MCPA-conjugates in urine and serum of diseased horses. Furthermore, cograzing healthy horses, which were present on AM affected pastures, were also investigated. AM-pastures in Germany were visited to identify seeds of Acer pseudoplatanus and serum (n = 8 as well as urine (n = 6 from a total of 16 diseased horses were analyzed for amino acid composition by LC-ESI-MS/MS, with a special focus on the content of HGA. Additionally, the content of its toxic metabolite was measured in its conjugated form in body fluids (UPLC-MS/MS. The seeds contained 1.7-319.8 μg HGA/g seed. The content of HGA in serum of affected horses ranged from 387.8-8493.8 μg/L (controls < 10 μg/L, and in urine from 143.8-926.4 μg/L (controls < 10 μg/L, respectively. Healthy cograzing horses on AM-pastures showed higher serum (108.8 ± 83.76 μg/L and urine concentrations (26.9 ± 7.39 μg/L compared to control horses, but lower concentrations compared to diseased horses. The range of MCPA-carnitine and creatinine concentrations found in diseased horses in serum and urine were 0.17-0.65 mmol/L (controls < 0.01, and 0.34-2.05 μmol/mmoL (controls < 0.001, respectively. MCPA-glycine levels in urine of cograzing horses were higher compared to controls. Thus, the causal link between HGA intoxication and disease outbreak

Lyme neuroborreliosis--characterized as chronic, necrosuppurative to nonsuppurative, perivascular to diffuse meningoradiculoneuritis--was diagnosed in 2 horses with progressive neurologic disease. In 1 horse, Borrelia burgdorferi sensu stricto was identified by polymerase chain reaction amplification of B burgdorferi sensu stricto-specific gene targets (ospA, ospC, flaB, dbpA, arp). Highest spirochetal burdens were in tissues with inflammation, including spinal cord, muscle, and joint capsule. Sequence analysis of ospA, ospC, and flaB revealed 99.9% sequence identity to the respective genes in B burgdorferi strain 297, an isolate from a human case of neuroborreliosis. In both horses, spirochetes were visualized in affected tissues with Steiner silver impregnation and by immunohistochemistry, predominantly within the dense collagenous tissue of the dura mater and leptomeninges.

Full Text Available Rose Bengal Plate test (RBPT and Serum Agglutination test (SAT were used to monitor the seroprevalence of brucellosis in horses in and around Faisalabad, Pakistan. Sera were screened by RBPT and positive or doubtful sera were further processed by SAT for confirmation. The overall seroprevalence of brucellosis in horses was 20.7 and 17.7% by RBPT and SAT, respectively. Source wise seroprevalence of brucellosis was 19.8, 25.5, 2.9 and 0% in horses of Remount Area Faisalabad, Remount Area Toba Tek Singh, private and Livestock Management Department University of Agriculture Faisalabad, respectively. Sex wise seroprevalence in horses was 9.67 and 17.7% in male and female, respectively. In relation to age, seroprevalence was 12.9, 16.5, 14.8 and 20.6%, in horses of 1-5, 6-10, 11-15 and above 15 years of age, respectively. Highest seroprevalence was recorded in horses of above 15 years of age. Depending upon the body condition, the seroprevalence was 9.7, 13, and 20% in poor fair, and good body conditioned horses, respectively. Seroprevalence of brucellosis on the basis of parity was 19.2, 20.9, 18.7, 16.6, and 21.1% in 0, 1, 2, 3 and above 3 foaling females, respectively. Prevalence of brucellosis in different breeds of horses was 22.4, 17.1, 25.7 and 0.0% in Desi, Thoroughbred, Crossbred and Arabian horses, respectively. However, statistically, in relation to various factors like source, sex, body condition, parity and breed of horses, a non significant difference was observed among various groups. Statistically a significant difference (P<0.001 in seroprevalence was observed with respect to age, only.

To compare survival and complications in horses undergoing large colon resection with either sutured end-to-end or stapled functional end-to-end anastomoses. Retrospective cohort study. Twenty-six client-owned horses with gastrointestinal disease. Retrospective data were retrieved from the medical records of 26 horses undergoing colectomy, including 14 horses with sutured end-to-end and 12 horses with stapled functional end-to-end anastomoses, between 2003 and 2016. Records were evaluated for signalment, medical and surgical treatments, and survival to hospital discharge. Long-term follow-up was obtained through owner contact. Continuous variables were compared with Mann-Whitney tests. Fisher's exact testing was used to compare survival to hospital discharge. Survival time was compared by constructing Kaplan-Meier survival curves and performing log-rank curve comparison testing. Mean age of horses undergoing colectomy was 13 years. Reason for colectomy was prophylaxis (12) or salvage (14). Mean surgical time was 169 minutes. Mean hospitalization time was 9 days, which did not differ with anastomosis type (P = .62). Nine of 12 horses undergoing stapled functional end-to-end anastomosis and 12 of 14 horses undergoing sutured end-to-end anastomosis survived to hospital discharge (P = .63). Survival time did not differ with anastomosis technique (P = .35). Short- and long-term survival outcomes are not different between sutured end-to-end or stapled functional end-to-end anastomoses in horses undergoing colectomy. © 2017 The American College of Veterinary Surgeons.

To report use of transendoscopic electrohydraulic shockwave lithotripsy for fragmentation of urinary calculi in horses. Case series. Male horses (n = 21). Fragmentation of cystic calculi (median, 6 cm diameter; range, 4-11 cm diameter) was achieved by transurethral endoscopy in standing sedated horses using an electrohydraulic shockwave fiber introduced through the biopsy channel of an endoscope. The fiber was advanced until it contacted the calculus. Repeated activation of the fiber was used to disrupt the calculus into fragments calculus removal was achieved in 20 horses (95%) with mean total surgical time of 168.6 minutes (range, 45-450). In the 20 horses with single calculi, 1-6 sessions were required to completely fragment the calculus. Except for 1 horse, in which perineal urethrotomy was eventually performed for complete fragment removal, fragments calculi were excreted via the urethra. Postoperative complications included hematuria because of severe mucosal erosion (n = 2), dysuria because of a trapped urethral fragment (2), small amount of urinary debris (1). One horse was euthanatized because of bladder rupture. Complete clearance of calculi and urinary debris was confirmed endoscopically 20 (3-45) days after the last session. Telephone follow-up (mean, 18.8 months; range, 7-24 months) revealed that horses had returned to previous activity levels without recurrence of clinical signs. Transendoscopic electrohydraulic lithotripsy appears to be an effective method for fragmentation of low-density calcium carbonate cystic calculi in male horses.

A countrywide survey of radon concentrations in Estonian dwellings was carried out during the period 1998-2001. The survey formed a part of the cooperation program on radiation protection between the Estonian Radiation Protection (Kiirguskeskus) Centre and the Swedish Radiation Protection Authority (SSI). The survey included measurements in a number of dwellings representative for Estonia in detached houses and multifamily buildings (only dwellings on the bottom floor were included in the survey). Altogether, radon concentrations were measured in 515 dwellings, a number large enough to be statistically significant. All measurements were made with alphatrack film detectors of the same type that SSI uses in Sweden. The measurements were made during a 2-3 month period during the winter half-year. Two detectors were used in each dwelling. In Estonia there are 0.17 million dwellings in detached houses and 0.45 million in multi apartment buildings. Of the 1.26 million inhabitants in Estonia. 0.36 million live in detached houses and 0.90 million in multi apartment buildings. Most of the latter were built during the Soviet occupation. Of the dwellings in multifamily buildings 30 % are assumed to be situated on the first floor. The mean radon concentration in dwellings in detached hoses, according to the survey results, is 103 Bq/m{sup 3}, in dwellings on the bottom floor in multi apartment buildings it is 78 Bq/m{sup 3}. In 1% of the dwellings the radon concentration exceeded 400 Bq/m{sup 3}. The highest radon concentration found in the study was 1040 Bq/m{sup 3}. Based on the assumption that the average radon concentration in the dwellings in multi-apartment buildings that are not situated on the bottom floor is 30 Bq/m{sup 3}, and that these dwellings constitute 70% of all dwellings in multi apartment buildings, the mean radon concentration in dwellings in multi apartment buildings is calculated to be 44 Bq/m{sup 3}.

A countrywide survey of radon concentrations in Estonian dwellings was carried out during the period 1998-2001. The survey formed a part of the cooperation program on radiation protection between the Estonian Radiation Protection (Kiirguskeskus) Centre and the Swedish Radiation Protection Authority (SSI). The survey included measurements in a number of dwellings representative for Estonia in detached houses and multifamily buildings (only dwellings on the bottom floor were included in the survey). Altogether, radon concentrations were measured in 515 dwellings, a number large enough to be statistically significant. All measurements were made with alphatrack film detectors of the same type that SSI uses in Sweden. The measurements were made during a 2-3 month period during the winter half-year. Two detectors were used in each dwelling. In Estonia there are 0.17 million dwellings in detached houses and 0.45 million in multi apartment buildings. Of the 1.26 million inhabitants in Estonia. 0.36 million live in detached houses and 0.90 million in multi apartment buildings. Most of the latter were built during the Soviet occupation. Of the dwellings in multifamily buildings 30 % are assumed to be situated on the first floor. The mean radon concentration in dwellings in detached hoses, according to the survey results, is 103 Bq/m 3 , in dwellings on the bottom floor in multi apartment buildings it is 78 Bq/m 3 . In 1% of the dwellings the radon concentration exceeded 400 Bq/m 3 . The highest radon concentration found in the study was 1040 Bq/m 3 . Based on the assumption that the average radon concentration in the dwellings in multi-apartment buildings that are not situated on the bottom floor is 30 Bq/m 3 , and that these dwellings constitute 70% of all dwellings in multi apartment buildings, the mean radon concentration in dwellings in multi apartment buildings is calculated to be 44 Bq/m 3 . The mean value for all Estonia dwellings is calculated to be 60 Bq/m 3 . Using

Inflammatory airway disease (IAD) in horses is a widespread, performance-limiting syndrome believed to develop in response to inhaled irritants in the barn environment. To evaluate changes in bronchoalveolar lavage fluid (BALF) cytology and exposure to particulates, endotoxin, and ammonia during horses' first month in training. Forty-nine client-owned 12- to 36-month-old Thoroughbred horses entering race training. In this prospective cohort study, a convenience sample of horses was assigned to be fed hay from a net (n = 16), whereas the remaining horses were fed hay from the ground (n = 33). BALF was collected at enrollment and after 14 and 28 days in training. Respirable particulate, inhalable particulate, respirable endotoxin, and ammonia concentrations were measured at the breathing zone of each horse weekly. Median respirable particulates were significantly higher when horses were fed from hay nets than when fed hay from the ground (hay net 0.28 mg/m(3) , no hay net 0.055 mg/m(3) , P horses were fed from hay nets. Feeding hay from a net resulted in significantly higher BALF eosinophil proportions over time (P Thoroughbreds, indicating a potential hypersensitivity to inhaled particulate allergens.

Holcomb, K E; Stull, C L; Kass, P H

2010-12-01

Closure of US equine slaughter facilities in 2007 along with the concomitant economic recession have contributed to a sharp increase in the number of unwanted horses throughout the United States, with estimates totaling 100,000 horses per year. The objective of the study was to obtain comprehensive data regarding nonprofit organizations caring for unwanted horses, along with the characteristics and outcome of horses relinquished to these organizations. Nonprofit organizations that accept relinquished equines were contacted to participate in a 90-question survey. Responding organizations (144 of 326 eligible) in 37 states provided information on 280 cases representative of the 7,990 horses relinquished between 2007 and 2009. Data collected characterized these organizations as being in existence for 6 yr, financially supported through donations and personal funds, dedicated to the care of only 10 to 20 horses on a property of just over 30 acres, and reliant on volunteers for help. Funding was the greatest challenge to continued operation of nonprofit equine organizations, with maintenance costs for the care of a relinquished horse averaging $3,648 per year. Financial hardship, physical inability, or lack of time to care for the horses by owners were the most common reasons for relinquishment, followed by seizure through law enforcement agencies for alleged neglect or abuse. Relinquished horses consisted of mostly light horse breeds (79.3%), with Thoroughbreds and Quarter Horses as the most represented breeds. The age of relinquished horses ranged from 3 d to 42 yr old (12.4 ± 0.5 yr). About one-half of the horses entered in the survey were considered unhealthy due to illness, injury, lameness, or poor body condition. For every 4 horses relinquished to a nonprofit organization, only 3 horses were adopted or sold between 2006 and 2009, and many organizations had refused to accept additional horses for lack of resources. The estimated maximum capacity for the 326

Theory of the Trojan-Horse method

International Nuclear Information System (INIS)

Baur, Gerhard; Typel, Stefan

2004-01-01

The Trojan-Horse method is an indirect approach to determine the energy dependence of S factors of astrophysically relevant two-body reactions. This is accomplished by studying closely related three-body reactions under quasi-free scattering conditions. The basic theory of the Trojan-Horse method is developed starting from a post-from distorted wave Born approximation of the T-matrix element. In the surface approximation the cross section of the three-body reaction can be related to the S-matrix elements of the two-body reaction. The essential feature of the Trojan-Horse method is the effective suppression of the Coulomb barrier at low energies for the astrophysical reaction leading to finite cross sections at the threshold of the two-body reaction. In a modified plane wave approximation the relation between the two-body and three-body cross sections becomes very transparent. Applications of the Trojan Horse Method are discussed. It is special interest that electron screening corrections are negligible due to the high projectile energy. (author)

Ärkamisaeg, Noor-Eesti ja miski nende vahel. Eesti kirjandusloo küsimusi Juhan Kunderi näitel / National Awakening , Young Estonia and Something In Between. Problems of Estonian Literary History in the Example of Juhan Kunder

Directory of Open Access Journals (Sweden)

Pille-Riin Larm

2013-12-01

Full Text Available According to the long-standing periodisation of Estonian literary history, the Estonian National Awakening that started in the mid-19th century was followed by a period of lesser creativity and originality, which ended only with the breakthrough of the modernist Young Estonia group in 1905. In the canon of Estonian literature, Juhan Kunder (1852–1888, today known primarily for his fairy tales, one play and lyrics of one song, is placed in this intermediate period. This article first introduces the significance of Kunder in his time. He was a popular writer and a wellknown pedagogue, and a younger contemporary of the great figures of the National Awakening. As a critic, magazine editor and literary historian, his most important contribution to literary history was in the development of literary thought. It seems that several precedents that have been attributed to the Young Estonia group, e.g., valuing originality, writing well-argued criticism, etc., actually originated from an earlier period. Based on these observations, the author of this article believes that the current structure of Estonian literary history is not adequately justified, and she points out a semantic shift in the terms in use. It is true that Kunder was largely an epigone of his predecessors, but in the positive sense of the term, meaning that he continued their mission. Similarly, Kunder’s predecessor, the ‘first Young Estonian’ Kreutzwald, and a representative of his 20th-century successors, Friedebert Tuglas, were also epigones. During the period of Russification that started during his era, Kunder’s attitudes could be considered progressive. Kunder was also a 19th-century contemporary of the Young Estonia group and a true Young Estonian in the original sense of the term which emerged in this period: a Young Estonian introduced new initiatives and was a leader of the national movement. Epigonism and membership in Young Estonia can be seen as the keys to cultural

Dabareiner, R.M.; White, N.A.; Sullins, K.E.

1996-01-01

Medical records, radiographs, and sonograms of 63 horses with metacarpophalangeal joint synovial pad proliferation were examined retrospectively. AR horses had lameness, joint effusion, or both signs associated with one or both metacarpophalangeal joints. Bony remodeling and concavity of the distodorsal aspect of the third metacarpal bone (Mc3) just proximal to the metacarpal condyles was identified by radiography in 71 joints (93%); 24 joints (32%) had radiographic evidence of a chip fracture located at the proximal dorsal aspect of the proximal phalanx. Fifty-four joints (71%) were examined by ultrasound. The mean +- SD sagittal thickness of the synovial pad was 11.3 +- 2.8 mm. Seventy-nine percent of the horses had single joint involvement with equal distribution between the right and left forelimbs. Sixty-eight joints in 55 horses were treated by arthroscopic surgery. Sixty joints (88%) had debridement of chondral or osteochondral fragmentation from the dorsal surface of Mc3 beneath the synovial pad and 30 joints (44%) had a bone chip fracture removed from the medial or lateral proximal dorsal eminence of the proximal phalanx. Complete or partial excision of both medial and lateral synovial pads was completed in 42 joints. Only the medial synovial pad was excised or trimmed in 21 joints, and 5 joints had only the lateral pad removed. Eight joints in eight horses were treated by stall rest, administration of intra-articular medication and systemic nonsteroidal anti-inflammatory drugs. Follow-up information was obtained for 50 horses treated surgically and for eight horses treated medically. Forty-three (86%) that had surgery returned to racing; 34 (68%) raced at an equivalent or better level than before surgery. Three (38%) of the medically treated horses returned to racing; only one horse raced better than the preinjury level. Horses that returned to racing at a similar or equal level of performance were significantly younger in age than horses returning at a

Full Text Available Abstract Background Many colic horses are compromised due to the disease state and from hours of starvation and sometimes long trailer rides. This could influence their muscle energy reserves and affect the horses' ability to recover. The principal aim was to follow metabolic parameter before, during, and up to 7 days after anaesthesia in healthy horses and in horses undergoing abdominal surgery due to colic. Methods 20 healthy horses given anaesthesia alone and 20 colic horses subjected to emergency abdominal surgery were anaesthetised for a mean of 228 minutes and 183 minutes respectively. Blood for analysis of haematology, electrolytes, cortisol, creatine kinase (CK, free fatty acids (FFA, glycerol, glucose and lactate was sampled before, during, and up to 7 days after anaesthesia. Arterial and venous blood gases were obtained before, during and up to 8 hours after recovery. Gluteal muscle biopsy specimens for biochemical analysis of muscle metabolites were obtained at start and end of anaesthesia and 1 h and 1 day after recovery. Results Plasma cortisol, FFA, glycerol, glucose, lactate and CK were elevated and serum phosphate and potassium were lower in colic horses before anaesthesia. Muscle adenosine triphosphate (ATP content was low in several colic horses. Anaesthesia and surgery resulted in a decrease in plasma FFA and glycerol in colic horses whereas levels increased in healthy horses. During anaesthesia muscle and plasma lactate and plasma phosphate increased in both groups. In the colic horses plasma lactate increased further after recovery. Plasma FFA and glycerol increased 8 h after standing in the colic horses. In both groups, plasma concentrations of CK increased and serum phosphate decreased post-anaesthesia. On Day 7 most parameters were not different between groups. Colic horses lost on average 8% of their initial weight. Eleven colic horses completed the study. Conclusion Colic horses entered anaesthesia with altered

Genetic polymorphism of IHH gene were investigated in Angloarabian, Polish Coldblood and Polish Halfbred horses with the inclusion of a group of Polish Halfbreds affected by osteochondrosis. IHH is a good candidate gene for association study of developmental disorders mainly affecting skeleton development. DNA sequence spanning IHH gene annotated in the horse genome and its putative promoter were investigated using SANGER sequencing. Analysis of genetic variability at polymorphic sites in the IHH gene body and the promoter region confirmed genetic differences between warmblood and coldblood horse breeds. A test for allelic and genotypic association at particular SNP sites revealed no association with osteochondrosis in investigated group of Polish Halfbreds. It was concluded that participation of different warmblood breeds in pedigrees of Polish Halfbreds make it difficult to search for genetic variants being associated with this complex disorder in this breed. IHH gene polymorphism investigated among three different horse populations would be valuable for further studies on equine bone developmental disorders. © 2013 The Authors.

The horse was domesticated only 5.5 KYA, thousands of years after dogs, cattle, pigs, sheep, and goats. The horse nonetheless represents the domestic animal that most impacted human history; providing us with rapid transportation, which has considerably changed the speed and magnitude of the circulation of goods and people, as well as their cultures and diseases. By revolutionizing warfare and agriculture, horses also deeply influenced the politico-economic trajectory of human societies. Reciprocally, human activities have circled back on the recent evolution of the horse, by creating hundreds of domestic breeds through selective programs, while leading all wild populations to near extinction. Despite being tightly associated with humans, several aspects in the evolution of the domestic horse remain controversial. Here, we review recent advances in comparative genomics and paleogenomics that helped advance our understanding of the genetic foundation of domestic horses.

Regular exercise testing in Warmblood sport horses may, as in racing, potentially help to characterise fitness indices in different disciplines and at various competition levels and assist in understanding when a horse is 'fit to compete'. In this review an overview is given of the current state of the art of exercise testing in the Olympic disciplines of eventing, show jumping and dressage, and areas for further development are defined. In event horses, a simple four-step incremental exercise test measuring heart rate (HR), lactate concentration (LA) and velocity (V) is most often used. In dressage and riding horses, a wide variety of exercise tests have been developed, including incremental exercise tests, indoor riding tests and lunging tests. In show jumping, the use of a five-step incremental exercise test and exercise tests evaluating technical skills and fatigue of the horse has been reported. The velocity at a plasma LA of 4 mmol/L (VLA4) and HR recovery during submaximal exercise intensity have been shown to be the best parameters in event horses for predicting performance and impending injuries. In riding horses, the fitness level of horses is also an important determinant of injuries. Implementation of regular exercise testing and monitoring of training sessions may have important added value in the assessment of performance ability and potential future injuries in Warmblood sport horses. However, there is an urgent need to standardise methodologies and outcome parameters in order to make results comparable. Copyright © 2014 Elsevier Ltd. All rights reserved.

Hungry Horse Dam fisheries mitigation program: Fish passage and habitat improvement in the Upper Flathead River basin

International Nuclear Information System (INIS)

Knotek, W.L.; Deleray, M.; Marotz, B.

1997-08-01

In the past 50 years, dramatic changes have occurred in the Flathead Lake and River system. Degradation of fishery resources has been evident, in part due to deterioration of aquatic habitat and introduction of non-endemic fish and invertebrate species. Habitat loss has been attributed to many factors including the construction and operation of Hungry Horse Dam, unsound land use practices, urban development, and other anthropogenic and natural disturbances. Fish migration has also been limited by barriers such as dams and impassible culverts. Cumulatively, these factors have contributed to declines in the distribution and abundance of native fish populations. Recovery of fish populations requires that a watershed approach be developed that incorporates long-term aquatic habitat needs and promotes sound land use practices and cooperation among natural resource management agencies. In this document, the authors (1) describe completed and ongoing habitat improvement and fish passage activities under the Hungry Horse Fisheries Mitigation Program, (2) describe recently identified projects that are in the planning stage, and (3) develop a framework for identifying prioritizing, implementing, and evaluating future fish habitat improvement and passage projects

Rhodococcus equi is a common cause of pneumonia in foals and has extensive clinical, economic and possibly zoonotic consequences. This bacterium survives well in the environment and may be considered as normal flora of adult horses. Certain strains of this bacterium are extremely virulent in foals, and early identification and intervention is crucial for prognosis. Rhodococcus equi is endemic in many parts of the world and occasionally isolated in Israel. This study was designed to evaluate R. equi seroprevalence in adult horses in Israel to indirectly indicate the potential level of exposure of susceptible foals. Sera were collected from 144 horses during spring 2011 and from 293 horses during fall 2014, and the presence of antibodies against virulent R. equi was detected by enzyme-linked immunosorbent assay. Equine seroprevalence of R. equi was found to be 7.6% in 2011 and 5.1% in 2014. Only one farm had seropositive horses in 2011, whereas several farms had seropositive horses in 2014. No significant risk factors for seropositivity were found. Rhodococcus equi appears to be endemic in Israel. This is the first survey of R. equi in Israel that provides information on the epidemiology of this important bacterium.

Procaterol (PCR) is a beta-2-adrenergic bronchodilator widely used in Japanese racehorses for treating lower respiratory disease. The pharmacokinetics of PCR following single intravenous (0.5 μg/kg) and oral (2.0 μg/kg) administrations were investigated in six thoroughbred horses. Plasma and urine concentrations of PCR were measured using liquid chromatography-mass spectrometry. Plasma PCR concentration following intravenous administration showed a biphasic elimination pattern. The systemic clearance was 0.47 ± 0.16 L/h/kg, the steady-state volume of the distribution was 1.21 ± 0.23 L/kg, and the elimination half-life was 2.85 ± 1.35 h. Heart rate rapidly increased after intravenous administration and gradually decreased thereafter. A strong correlation between heart rate and plasma concentration of PCR was observed. Plasma concentrations of PCR after oral administration were not quantifiable in all horses. Urine concentrations of PCR following intravenous and oral administrations were quantified in all horses until 32 h after administration. Urine PCR concentrations were not significantly different on and after 24 h between intravenous and oral administrations. These results suggest that the bioavailability of orally administrated PCR in horses is very poor, and the drug was eliminated from the body slowly based on urinary concentrations. This report is the first study to demonstrate the pharmacokinetic character of PCR in thoroughbred horses. © 2015 John Wiley & Sons Ltd.

1998-07-01

Full Text Available Genetic variability at 7 blood-group and 10 biochemical genetic loci was examined in 3 South African horse breeds, the Nooitgedacht, Boerperd and Basuto Pony. Observed heterozygosity for these breeds was intermediate for domestic horses, with the highest heterozygosity in the Boerperd and the lowest in the Basuto Pony. The 3 breeds show greater genetic similarity to each other than to other domestic horse breeds. Compared to other breeds, the South African breeds show greater genetic similarity to breeds such as the Thoroughbred, Holstein, Trakehner and Hanovarian and also to North American breeds such as the Saddlebred, Standardbred and Morgan Horse.

Sanada, Y; Noda, H; Nagahata, H

1992-08-01

Serological survey of Rhodococcus equi infection in horses in Hokkaido was performed using ELISA. Of 2,879 horse sera, 318 (11.0%) gave antibody-positive (OD greater than or equal to 0.3) reactions. The antibody-positive rate of female was significantly higher (p less than 0.01) than that of male, and no statistical difference between Anglo-Arab and thoroughbred was detected in the antibody-positive rate. The maximum antibody-positive rate (27.1%) was shown at 14 years of age. The antibody-positive rates on the 160 farms were found to vary widely from 0 to 78.9%. A significant difference (p less than 0.01) in the antibody-positive rate was detected among horse farms. It was elucidated that 100 (62.5%) out of 160 horse farms had an antibody-positive horse. These results indicate that R. equi was widespread on horse farms, and the level of environmental contamination with R. equi differed among horse farms.

A multi proxy approach was applied in the reconstruction of the architecture of Medieval horse stable architecture, the maintenance practices associated with that structure as well as horse alimentation at the beginning of 13th century in Central Europe. Finally, an interpretation of the local vegetation structure along Morava River, Czech Republic is presented. The investigated stable experienced two construction phases. The infill was well preserved and its composition reflects maintenance practices. The uppermost part of the infill was composed of fresh stabling, which accumulated within a few months at the end of summer. Horses from different backgrounds were kept in the stable and this is reflected in the results of isotope analyses. Horses were fed meadow grasses as well as woody vegetation, millet, oat, and less commonly hemp, wheat and rye. Three possible explanations of stable usage are suggested. The stable was probably used on a temporary basis for horses of workers employed at the castle, courier horses and horses used in battle. PMID:24670874

Life Cycle Assessment of Horse Manure Treatment

Directory of Open Access Journals (Sweden)

Ola Eriksson

2016-11-01

Full Text Available Horse manure consists of feces, urine, and varying amounts of various bedding materials. The management of horse manure causes environmental problems when emissions occur during the decomposition of organic material, in addition to nutrients not being recycled. The interest in horse manure undergoing anaerobic digestion and thereby producing biogas has increased with an increasing interest in biogas as a renewable fuel. This study aims to highlight the environmental impact of different treatment options for horse manure from a system perspective. The treatment methods investigated are: (1 unmanaged composting; (2 managed composting; (3 large-scale incineration in a waste-fired combined heat and power (CHP plant; (4 drying and small-scale combustion; and (5 liquid anaerobic digestion with thermal pre-treatment. Following significant data uncertainty in the survey, the results are only indicative. No clear conclusions can be drawn regarding any preference in treatment methods, with the exception of their climate impact, for which anaerobic digestion is preferred. The overall conclusion is that more research is needed to ensure the quality of future surveys, thus an overall research effort from horse management to waste management.

The refractive state of the eye in Icelandic horses with the Silver mutation.

Science.gov (United States)

Johansson, Maria K; Jäderkvist Fegraeus, Kim; Lindgren, Gabriella; Ekesten, Björn

2017-06-02

The syndrome Multiple Congenital Ocular Anomalies (MCOA) is a congenital eye disorder in horses. Both the MCOA syndrome and the Silver coat colour in horses are caused by the same missense mutation in the premelanosome protein (PMEL) gene. Horses homozygous for the Silver mutation (TT) are affected by multiple ocular defects causing visual impairment or blindness. Horses heterozygous for the Silver mutation (CT) have less severe clinical signs, usually cysts arising from the ciliary body iris or retina temporally. It is still unknown if the vision is impaired in horses heterozygous for the Silver mutation. A recent study reported that Comtois horses carrying the Silver mutation had significantly deeper anterior chambers of the eye compared to wild-type horses. This could potentially cause refractive errors. The purpose of the present study was to investigate if Icelandic horses with the Silver mutation have refractive errors compared to wild-type horses. One hundred and fifty-two Icelandic horses were included in the study, 71 CT horses and five TT horses. All horses were genotyped for the missense mutation in PMEL. Each CT and TT horse was matched by a wild-type (CC) horse of the same age ± 1 year. Skiascopy and a brief ophthalmic examination were performed in all horses. Association between refraction and age, eye, genotype and sex was tested by linear mixed-effect model analysis. TT horses with controls were not included in the statistical analyses as they were too few. The interaction between age and genotype had a significant impact on the refractive state (P = 0.0001). CT horses older than 16 years were on average more myopic than wild-type horses of the same age. No difference in the refractive state could be observed between genotypes (CT and CC) in horses younger than 16 years. TT horses were myopic (-2 D or more) in one or both eyes regardless of age. Our results indicate that an elderly Icelandic horse (older than 16 years) carrying the Silver

Full Text Available The aim of this study was to evaluate the conformation of stallions of the breeds American Quarter Horse (AQH, American Paint Horse (APH, Appaloosa (Appa, the Lipizzaner horse (LH and the Old Kladruby horse (OKH. Representatives of these breeds are characterized as the descendants of horses on the base of the Arab-Berber blood. Western breeds (AQH, APH, Appa due to different environmental conditions, nutrition and the other structure under the influence of a different type of use, type of riding demands differed considerably from the original Spanish-type horses. It was measured a total of 24 body dimensions. Representatives of The American western breeds are statistically highly conclusively (P ≤ 0.01 in 23 of the 24 observed effects. To be precise, they are: smaller wither height as measured by stick, lower at the tail-set, longer neck, narrower chest, longer oblique body length, wider front pelvis length, longer pelvis bones, longer femur bones, shorter hind cannons.A statistically significant difference (P ≤ 0.05 was found in the length of the humerus, where the Old Kladruby Horse has a humerus that is longer by 2.34 cm than that of the APH. The Lipizzaner horse differs statistically highly conclusively (P ≤ 0.01 from the Appaloosa and Old Kladruby horse in the tape length of its head.

Injury to the proximal suspensory ligament is a common cause of lameness in cutting horses. Radiographic and ultrasonographic imaging of lesions responsible for lameness can provide ambiguous results. MRI provides the most comprehensive diagnostic imaging evaluation of lesions specifically affecting cutting horses. To describe the distribution and severity of bone and soft tissue lesions present in the proximal metacarpus of Quarter Horse cutting horses and to assess the impact of these lesions on return to competition. Retrospective case series. Retrospective analysis of 32 cutting horses referred for MRI of the proximal metacarpus between 2009 and 2012 with a 2-year follow-up period. MRI studies were evaluated by a board-certified veterinary radiologist; the severity of lesions was graded from 0 (absent) to 3 (severe). A total of 20 right and 24 left forelimbs (12 bilateral studies) of 32 horses were evaluated. The most common findings were: third metacarpal (McIII) sclerosis at the proximal suspensory ligament (PSL) origin (42/44), McIII resorption at the PSL origin (32/44), PSL dorsal margin fibre irregularity (30/44) and McIII bone contusion (22/39). Of the 30 horses, 22 horses successfully returned to competition, irrespective of severity of injury. Strong correlation exists between the degree of resorption in the palmar cortex of proximal McIII, degree of McIII sclerosis and severity of dorsal margin fibre irregularity. Statistical significance was limited by small study population. Further analysis of prognosis was limited by availability of comprehensive medical records. Cutting horses with proximal metacarpal pain have significant pathological change within the proximal suspensory ligament and its enthesis on the palmar cortex of McIII. Severity of lesions and degree of lameness at the time of diagnosis does not influence return to performance. Accurate diagnosis of proximal metacarpal lesions based on MRI offers clinicians the capacity to select

Patterns of serum biochemical parameters vary among horse breeds. The objective of the present study was to compare serum lipoproteins of Iranian Caspian ponies with those of other horses (Arabs and Thoroughbreds) in the Iranian region. Serum lipoprotein values were determined by agar-agarose gel electrophoresis and measured by scan densitometry. Moreover, serum triglyceride and cholesterol concentrations were determined and the results were analysed by one-way analysis of variance. Serum triglyceride and cholesterol values were 1.13 +/- 0.23 and 2.38 +/- 0.18 mmol/l in Caspian ponies, 1.96 +/- 0.49 and 1.92 +/- 0.25 mmol/l in Arab horses and 1.38 +/- 0.26 and 2.17 +/- 0.53 mmol/l in Thoroughbred horses. The relative percentages of alpha- (72.63 +/- 17.76%) and beta-lipoproteins (29.10 +/- 5.49%) in serum electrophoretic tracings from Caspian ponies were not significantly different from those of other horses (p > 0.05). The lipoprotein phenotype in Caspian ponies may be useful for evaluating metabolic diseases.

2013-01-01

Background This study was performed to determine the prevalence of ulcers in the gastric squamous and glandular mucosa in Polish pleasure horses. Study design Medical records from gastroscopic examinations of 108 pleasure horses of different breeds were reviewed. The study population consisted of two groups; group I (n = 48) with horses that expressed mild clinical signs of gastric ulcer syndrome (EGUS) including poor appetite, slight weight loss or poor body condition, and group II (n = 60) with horses that had no signs of gastrointestinal problems. The age range was 4–10 years, including 5 males, 34 castrated males (geldings) and 69 mares. The prevalence, distribution and severity of gastric ulcers were recorded. Lesions involving the squamous mucosa and the glandular mucosa of the antrum and pylorus were graded and compared between groups. Results Significant difference was found in the presence and severity of gastric ulcers between the two groups of horses. The overall prevalence of gastric ulcers in the first group of horses (n = 48) was 59% while in the group of clinically healthy horses (n = 60) the prevalence of gastric lesion was 40% (P = 0.004). Almost 19% of horses from group I had between 6–10 lesions (EGUS score III) and nearly 19% had either >10 localized lesions or very large diffuse lesions (EGUS number score IV). The number of ulcerations in affected horses were significantly lower in group II compared to group I (P = 0.016) as 10% of horses had 6–10 lesions (EGUS number score III) and nearly 14% had either >10 localized lesions or very large diffuse lesions (EGUS number score IV). Gastroscopy revealed that nearly 32% of horses from the second group had an ulceration EGUS score ≥ II. Discussion and conclusions This study confirms that gastric ulcerations can be prevalent in apparently clinically normal pleasure horses and a complete gastroscopic examination including the examination of the pylorus is advisable

Pimobendan is an inodilator used in dogs for the management of heart failure due to myxomatous valve disease or dilated cardiomyopathy. The lack of data regarding the effects of pimobendan in horses prevents the rational use of this drug. To determine the cardiovascular effects of pimobendan in healthy mature horses. Randomised experimental study. Five horses were fasted overnight prior to receiving i.v. pimobendan (0.25 mg/kg bwt), intragastric (i.g.) pimobendan (0.25 mg/kg bwt) or i.g. placebo with a washout period of one week between each administration. Horses were instrumented for the measurement of right ventricular (RV) minimum pressure, RV maximum pressure, RV end diastolic pressure, and maximum rate of increase and decrease in RV pressure before and 0.5, 1, 2, 4, and 8 h after drug administration. Arterial blood pressure, central venous pressure, cardiac output and heart rate were measured at the same time points. Data were expressed as a maximum percentage of change over baseline values. There were no adverse effects associated with administration of pimobendan. The percentage increase in heart rate was significantly greater for horses given pimobendan i.g. (33 ± 4%) and i.v. (36 ± 14%) than for those given a placebo (-2 ± 7%). The percentage increase in maximum rate of increase in RV pressure (35 ± 36%) and the percentage decrease in minimum pressure (47 ± 24%) and end diastolic pressure (34 ± 13%) were significantly greater in horses given pimobendan i.v. than in those given placebo. Other variables measured were not significantly different between treatment groups. Pimobendan administered i.v. has positive chronotropic and inotropic effects in healthy mature horses and warrants further investigation for the treatment of heart failure in horses. © 2015 EVJ Ltd.

Does work affect personality? A study in horses.

We used immunohistochemistry to examine myosin heavy-chain (MyHC)-based fiber-type profiles of the right and left cricoarytenoideus dorsalis (CAD) and arytenoideus transversus (TrA) muscles of six horses without laryngoscopic evidence of recurrent laryngeal neuropathy (RLN). Results showed that CAD and TrA muscles have the same slow, 2a, and 2x fibers as equine limb muscles, but not the faster contracting fibers expressing extraocular and 2B MyHCs found in laryngeal muscles of small mammals. Muscles from three horses showed fiber-type grouping bilaterally in the TrA muscles, but only in the left CAD. Fiber-type grouping suggests that denervation and reinnervation of fibers had occurred, and that these horses had subclinical RLN. There was a virtual elimination of 2x fibers in these muscles, accompanied by a significant increase in the percentage of 2a and slow fibers, and hypertrophy of these fiber types. The results suggest that multiple pathophysiological mechanisms are at work in early RLN, including selective denervation and reinnervation of 2x muscle fibers, corruption of neural impulse traffic that regulates 2x and slow muscle fiber types, and compensatory hypertrophy of remaining fibers. We conclude that horses afflicted with mild RLN are able to remain subclinical by compensatory hypertrophy of surviving muscle fibers.

Residues of the insect growth regulator diflubenzuron were quantified on horse chestnut (Aesculus hippocastanum L.) leaves treated with a diflubenzuron 480 g litre(-1) SC, Dimilin. To analyse the samples, an analytical procedure was developed involving a simple extraction step followed by high-performance liquid chromatography on an octadecyl-modified silica column with methanol + 0.01 M ammonium acetate mobile phase. The results showed diflubenzuron to be highly stable on horse chestnut leaves; more than 4 months (127 days) after application, 38% (on average) of the insecticide still remained on/in the leaves. The data confirmed biological observations showing diflubenzuron's long-term efficacy against the horse chestnut leafminer, Cameraria ohridella Deschka and Dimić, which is the most important pest of the horse chestnut in Europe. The hypothesis of possible penetration of diflubenzuron into the leaf mass is explored and discussed.

4 horses with a history of neck pain, abnormal head carriage, and related inability to perform were examined. Cranial nuchal bursitis was diagnosed in 2 horses, and caudal nuchal bursitis was diagnosed in the other 2. All 4 horses had prominent swelling in the region between the frontal bone and temporal fossa (ie, the poll) and abnormal head carriage. Ultrasonographic examination revealed fluid distention and synovial thickening of the cranial or caudal nuchal bursa in all 4 horses. Ultrasonography-guided aspiration of the affected region was performed successfully in 3 horses. Radiography revealed bony remodeling and mineralization over the dorsal aspect of the atlas in 1 horse and a radiolucency at the axis in another. Nuclear scintigraphy revealed an increase in radioisotope uptake at the level of C2 in 1 horse. Although a septic process was considered among the differential diagnoses in all horses, a septic process could only be confirmed in 1 horse. All horses were refractory to conservative management consisting of intrabursal injection of anti-inflammatory medications. Bursoscopic debridement and lavage of the affected bursae resulted in resolution of the clinical signs in all horses, and they all returned to their intended use. Cranial and caudal nuchal bursitis, of nonseptic or septic origin, should be considered as a differential diagnosis in horses with head and neck pain. Horses undergoing surgical intervention consisting of nuchal bursoscopy have the opportunity to return to their original degree of exercise.

Seroprevalence of Rhodococcus equi in horses in Israel

Directory of Open Access Journals (Sweden)

2017-06-01

Full Text Available Rhodococcus equi is a common cause of pneumonia in foals and has extensive clinical, economic and possibly zoonotic consequences. This bacterium survives well in the environment and may be considered as normal flora of adult horses. Certain strains of this bacterium are extremely virulent in foals, and early identification and intervention is crucial for prognosis. Rhodococcus equi is endemic in many parts of the world and occasionally isolated in Israel. This study was designed to evaluate R. equi seroprevalence in adult horses in Israel to indirectly indicate the potential level of exposure of susceptible foals. Sera were collected from 144 horses during spring 2011 and from 293 horses during fall 2014, and the presence of antibodies against virulent R. equi was detected by enzyme-linked immunosorbent assay. Equine seroprevalence of R. equi was found to be 7.6% in 2011 and 5.1% in 2014. Only one farm had seropositive horses in 2011, whereas several farms had seropositive horses in 2014. No significant risk factors for seropositivity were found. Rhodococcus equi appears to be endemic in Israel. This is the first survey of R. equi in Israel that provides information on the epidemiology of this important bacterium.

2007-07-01

Full Text Available Abstract Background The Icelandic horse is a pristine breed of horse which has a pure gene pool established more than a thousand years ago, and is approximately the same size as living and extinct wild breeds of horses. This study was performed to compare the length of the skeletal growth period of the "primitive" Icelandic horse relative to that reported for large horse breeds developed over the recent centuries. This information would provide practical guidance to owners and veterinarians as to when the skeleton is mature enough to commence training, and would be potentially interesting to those scientists investigating the pathogenesis of osteochondrosis. Interestingly, osteochondrosis has not been documented in the Icelandic horse. Methods The radiographic closure time of the appendicular growth plates was studied in 64 young Icelandic horses. The results were compared with previously published closure times reported for other, larger horse breeds. The radiographs were also examined for any signs of developmental orthopaedic diseases. In order to describe further the growth pattern of the Icelandic horse, the total serum alkaline phosphatase (ALP activity was determined and the height at the withers was measured. Results Most of the examined growth plates were fully closed at the age of approximately three years. The horses reached adult height at this age; however ALP activity was still mildly increased over baseline values. The growth plates in the digits were the first to close at 8.1 to 8.5 months of age, and those in the regions of the distal radius (27.4 to 32.0 months, tuber olecrani (31.5 to 32.2 months, and the stifle (27.0 to 40.1 months were the last to close. No horse was found to have osteochondrosis type lesions in the neighbouring joints of the evaluated growth plates. Conclusion The Icelandic horse appears to have similar radiographic closure times for most of the growth plates of its limbs as reported for large new breeds of

2014-12-01

A cross-sectional study was conducted to determine the prevalence and species composition of lice infesting horses in three agroecological zones in seven different districts in central Oromia from November 2011 to April 2012. For this purpose, a total of 420 horses were thoroughly examined for presence of lice. Collected lice were identified to species level under a microscope. The study showed an overall prevalence of 28.8 % (121/420) lice infestation on horses. We identified two spp. of lice on horses namely, Bovicola (Werneckiella) equi and Haematopinus asini with an overall prevalence of 22.9 % (96/420) and 5.9 % (25/420), respectively. The overall prevalence of lice infestation on horses in districts was 48.3, 43.3, 33.3, 23.3, 21.7, 18.3 and 13.3 %, in Debre Brehan, Shashemene, Hawassa, Akaki, Adama, Modjo and Bishoftu, respectively. B. equi was encountered as the predominant species on horses in all districts. Higher overall prevalence of lice infestation was recorded in highland agroecology than mid and lowland agroecological zones. Similarly, our study revealed significantly higher overall prevalence of lice on saddle horses than on cart horses. In view of the findings of the present study two species of lice are responsible for health and welfare problems of horses in all the districts. Detailed epidemiological studies on the significance, prevalence and role of lice as vectors of zoonotic pathogens in different agroecological zones, breeds and management systems warrant urgent attention. Animal owners and veterinarians should consider lice control in horses as part of the ectoparasite control in other species of animals.

Post-anaesthetic myelomalacia in a horse : clinical communication

2005-06-01

Full Text Available This article describes a rare neurological complication of anaesthesia in a 2 year-old Clydesdale colt undergoing castration. Anaesthesia was induced with glyceryl guaiacol ether and ketamine and maintained with halothane. Following an uneventful anaesthetic of 40 minutes, the horse recovered from anaesthesia in a padded recovery stall. After approximately 70 minutes in the recovery stall, the horse attempted to stand and adopted a dog sitting position. One hundred and fifty minutes later, the horse became distressed and was sedated with xylazine. Clinical examination of the horse did not reveal any evidence of myositis or fractures. A neurological examination revealed an intact anal reflex, deep pain response in the hind legs, tail tone and voluntary movement of the hind legs was possible. The horse deteriorated neurologically over the next 24 hours and was euthanased on humane grounds. The horse was submitted for necropsy. Gross pathology was unremarkable except for a small amount of haemorrhage around the right kidney. Histopathology revealed no abnormalities in any muscle groups or peripheral nerves. Congestion and axonal swelling of the spinal cord was evident from T16 to S1. Ischaemic neurons were evident from L 1 to L 6. The most prominent lesions were at L4 and L5. A diagnosis of myelomalacia was made. This is a rare complication of anaesthesia in horses with 9 case studies appearing in the literature since 1979. This is the 1st case to be reported in South Africa. The speculated pathophysiology and risk factors for this complication are discussed.

The Contribution of Equitation Science to Minimising Horse-Related Risks to Humans

Directory of Open Access Journals (Sweden)

Melissa Starling

2016-02-01

Full Text Available Equitation science is an evidence-based approach to horse training and riding that focuses on a thorough understanding of both equine ethology and learning theory. This combination leads to more effective horse training, but also plays a role in keeping horse riders and trainers safe around horses. Equitation science underpins ethical equitation, and recognises the limits of the horse’s cognitive and physical abilities. Equitation is an ancient practice that has benefited from a rich tradition that sees it flourishing in contemporary sporting pursuits. Despite its history, horse-riding is an activity for which neither horses nor humans evolved, and it brings with it significant risks to the safety of both species. This review outlines the reasons horses may behave in ways that endanger humans and how training choices can exacerbate this. It then discusses the recently introduced 10 Principles of Equitation Science and explains how following these principles can minimise horse-related risk to humans and enhance horse welfare.

To determine history; clinical, radiographic, ultrasonographic, and scintigraphic features; management; and outcome associated with third trochanter fractures in horses. Retrospective case series. 8 horses. Records from 2000 to 2012 were reviewed, and signalment, case history, severity and duration of lameness, results of physical and lameness examinations, imaging findings, management, and outcome were evaluated. All horses had a history of acute onset of severe lameness. Four of the 8 horses had localizing physical signs of fracture. No specific gait characteristics were identified. Ultrasonographically, there was a single bony fragment displaced cranially in 7 of 8 horses and multiple bony fragments in 1. Concurrent gluteus superficialis muscle enthesopathy was identified in 7 horses. A standing craniolateral-caudomedial 25° oblique radiographic view was obtained in 3 horses to document the lesion and revealed in all 3 horses a simple complete longitudinal fracture between the midlevel and the base of the third trochanter. Nuclear scintigraphy was used to identify the affected area of the limb for further examination in 2 horses. Follow-up revealed that fractures healed with a fibrous union, with persistence of cranial displacement of the fragment. Lameness resolved after nonsurgical management for all horses. Fracture of the third trochanter should be considered as a cause of hind limb lameness in horses when the proximal portion of the limb is affected. Diagnosis can easily be made with ultrasonography, but nuclear scintigraphy may help in identifying the lesion. Prognosis for return to athletic activity is good after an appropriate period of rest and restricted exercise.

The aims of this work were to (1) develop a low-cost equine movement tracking collar based on readily available components, (2) conduct preliminary studies assessing the effects of both paddock size and internal fence design on the movements of domestic horses, with and without foals at foot, and (3) describe distances moved by mares and their foals. Additional monitoring of free-ranging feral horses was conducted to allow preliminary comparisons with the movement of confined domestic horses. A lightweight global positioning system (GPS) data logger modified from a personal/vehicle tracker and mounted on a collar was used to monitor the movement of domestic horses in a range of paddock sizes and internal fence designs for 6.5-day periods. In the paddocks used (0.8-16 ha), groups of domestic horses exhibited a logarithmic response in mean daily distance travelled as a function of increasing paddock size, tending asymptotically towards approximately 7.5 km/day. The distance moved by newborn foals was similar to their dams, with total distance travelled also dependent on paddock size. Without altering available paddock area, paddock design, with the exception of a spiral design, did not significantly affect mean daily distance travelled. Feral horses (17.9 km/day) travelled substantially greater mean daily distances than domestic horses (7.2 km/day in 16-ha paddock), even when allowing for larger paddock size. Horses kept in stables or small yards and paddocks are quite sedentary in comparison with their feral relatives. For a given paddock area, most designs did not significantly affect mean daily distance travelled.

2016-11-01

Recommendations for prophylactic vaccination against tetanus in horses vary greatly between countries and have scarce scientific support in the peer-reviewed literature. In human medicine, recommended booster vaccination intervals are also very variable, but are considerably longer than for horses. More information is needed about the duration of immunity induced by modern vaccines. To investigate if the duration of antibody titres previously determined to be protective against tetanus differ from what is indicated by recommended vaccination intervals for horses. Prospective seroconversion study. Thirty-four horses were enrolled for basic immunisation with an ISCOM Matrix-combination vaccine (Equilis Prequenza Te). Horses received the first vaccination at age 5-11 months, and the second dose 4 weeks later. A third vaccine dose was given 15-17 months after the second dose. Serum tetanus antibody titres were analysed by toxin-binding enzyme-linked immunosorbent assay 2 weeks as well as 14-16 months after the second dose. After the third vaccine dose, titres were checked once yearly for 3 years. Results were described by age and level of antibody titre at first sampling. Two weeks after the second dose, all horses (34/34) had antibody levels that exceeded the limit of detection, 0.04 iu/ml. After 16 months the levels were above 0.04 iu/ml in 28/33 horses, the remaining 5 horses potentially had suboptimal protection against tetanus. After the third vaccine dose antibody levels remained above 0.04 iu/ml in 25/26 horses for 1 year, 16/16 horses for 2 years, and 8/8 horses for 3 years. Horses that undergo basic immunisation with 3 doses of vaccine after age 5 months are likely to have serum antibody titres consistent with protection against tetanus for more than 3 years. Current guidelines for tetanus prophylaxis should be revised. © 2015 EVJ Ltd.

PERFORMANCE OF COLD-BLOODED HORSES IN SLOVAKIA

Full Text Available Horse breeding program is based on an assessment of their exterior, and is largely influenced by the performance. The objective of the work was to analyze the performance characteristics of cold-blooded horses in Slovakia using test of performance characteristics through carriage race. By evaluating the higher forms of utility control we concluded that scores in individual disciplines were very balanced during 2005-2008, which was due to a steady track of the horses involved and the carriagers. By increasing the number of new horses and new competitors in 2009 the average value of scores marked substantial deterioration, but this cannot be seen as degradation of performance of studied horses. By analysis of the factors affecting the score we found out, that gender as the only factor, did not have any significant impact on the studied disciplines of utility control. Carriager and the year of competition were amongst the factors mostly influencing the score. As the most successful line, whose representatives were most frequently and best ranked on the carriage races, we can choose the line of Bayard de Heredia. Its seven representatives participated in the period 2005-2011 altogether for 141-times and their average ranking ranged from 2.2 to 5.4.

The interest in equine dentistry has significantly increased in the last 15 years. On the part of the veterinarians as well as of the horse owners there is a strong attention to the topic. The aim of the questionnaire was to investigate amongst horse owners what their level of information and preferences about dental treatment are and how they are implemented. The questionnaire was translated into the three national languages and included 20 questions about level and sources of information, frequency of treatments and the horse owner's stance over sedation of the animals. With a return rate of 45% (1'466 of 3'250 sent questionnaires) significant conclusions could be drawn. Horse owners showed a strong demand for clarification regarding tooth problems, the causes, consequences and methods of treatment. More than half of the owners considered themselves not well informed. The treating person was in 66.7% a veterinarian with a special education. Horse owners indicated that information circulated most frequently by word of mouth recommendations and they explicitly wished information from professional and reliable sources. The questionnaire provided a clear result about current equine dental treatments. We suggest that they should be performed by veterinarians only with a special education.

Full Text Available This is the first case of African horse sickness (AHS in a dog where there was no apparent ingestion of horse meat. Significantly, the dog was part of a colony that resides in a Good Clinical Practice and Good Laboratory Practice accredited facility where complete history, weather and feeding records are maintained. The dog died after a week-long illness despite therapy. The principal post-mortem findings were severe hydrothorax and pulmonary consolidation (red hepatisation of the lungs. Histopathology revealed severe oedema and congestion of the lungs, hyaline degeneration of the myocardium and congestion of the liver sinusoids. Immunohistochemistry detected AHS-positive staining granules in the myocardium, whilst a real-time reverse transcription quantitative Polymerase chain reaction assay of tissue samples was strongly positive for African horse sickness virus nucleic acid. Other dogs on the property showed a 43%seroconversion rate to AHS.

Full Text Available Abstract Background Ranks have been used as phenotypes in the genetic evaluation of horses for a long time through the use of earnings, normal score or raw ranks. A model, ("underlying model" of an unobservable underlying variable responsible for ranks exists. Recently, a full Bayesian analysis using this model was developed. In addition, in reality, competitions are structured into categories according to the technical level of difficulty linked to the technical ability of horses (horses considered to be the "best" meet their peers. The aim of this article was to validate the underlying model through simulations and to propose a more appropriate model with a mixture distribution of horses in the case of a structured competition. The simulations involved 1000 horses with 10 to 50 performances per horse and 4 to 20 horses per event with unstructured and structured competitions. Results The underlying model responsible for ranks performed well with unstructured competitions by drawing liabilities in the Gibbs sampler according to the following rule: the liability of each horse must be drawn in the interval formed by the liabilities of horses ranked before and after the particular horse. The estimated repeatability was the simulated one (0.25 and regression between estimated competing ability of horses and true ability was close to 1. Underestimations of repeatability (0.07 to 0.22 were obtained with other traditional criteria (normal score or raw ranks, but in the case of a structured competition, repeatability was underestimated (0.18 to 0.22. Our results show that the effect of an event, or category of event, is irrelevant in such a situation because ranks are independent of such an effect. The proposed mixture model pools horses according to their participation in different categories of competition during the period observed. This last model gave better results (repeatability 0.25, in particular, it provided an improved estimation of average

Is there evidence of learned helplessness in horses?

Science.gov (United States)

Hall, Carol; Goodwin, Deborah; Heleski, Camie; Randle, Hayley; Waran, Natalie

2008-01-01

Learned helplessness is a psychological condition whereby individuals learn that they have no control over unpleasant or harmful conditions, that their actions are futile, and that they are helpless. In a series of experiments in which dogs were exposed to inescapable shocks, this lack of control subsequently interfered with the ability to learn an avoidance task. There is evidence that both neural adaptations and behavioral despair occur in response to uncontrollable aversive experiences in rodents, although this has yet to be demonstrated in other species such as horses. However, certain traditional methods of horse training and some behavioral modification techniques--it has been suggested--may involve aversive conditions over which the horse has little or no control. When training and management procedures are repeatedly unpleasant for the horse and there is no clear association between behavior and outcome, this is likely to interfere with learning and performance-in addition to compromising welfare. This article reviews published literature and anecdotal evidence to explore the possibility that the phenomenon, learned helplessness, occurs in the horse.

Peterson, P.R.; Pascoe, J.R.; Wheat, J.D.

1987-01-01

Fractures of Metacarpal and Metatarsal II and IV (the splint bones) were treated in 283 horses over an 11 year period. In 21 cases the proximal portion of the fractured bone was stabilized with metallic implants. One or more cortical bone screws were used in 11 horses, and bone plates were applied in 11 horses. One horse received both treatments. Complications of screw fixation included bone failure, implant failure, radiographic lucency around the screws, and proliferative new bone at the ostectomy site. Only two of the horses treated with screw fixation returned to their intended use. Complications of plate fixation included partial fixation failure (backing out of screws), wound drainage, and proliferative bony response around the plate. Six of the 11 horses treated by plate fixation returned to their intended use. The authors recommend consideration of plate fixation techniques for repair of fractures in the proximal third of the splint bone

The prevalence of Toxoplasma gondii, an economically important zoonotic protozoan, was investigated in horses slaughtered for export and human consumption in the North of Romania. Pairs of samples, sera and heart tissues, were collected from 82 slaughtered horses. Examination of horse sera by ELISA at a dilution of 1:10, and by modified agglutination test (MAT) at a dilution of 1:6, revealed that 32 (39%) and 31(37.8%) horses, respectively, had antibodies against T. gondii. Using polymerase chain reaction (PCR) analysis, T. gondii DNA was not found in any heart sample collected from horses. By bioassay in mice, we obtained viable isolates of T. gondii from two of ten horses determined to be strongly positive by serological assay/ELISA. The prevalence estimated in horses highlighted the potential risk for human contamination by consumption of raw or undercooked meat. Copyright © 2015 Elsevier B.V. All rights reserved.

To report the outcome of conservative management of unilateral fractures of the mandibular rami in horses. Retrospective case series. 24 client-owned horses with unilateral mandibular fractures METHODS: Medical records (January 2000-January 2014) of horses with unilateral mandibular ramus fractures were retrieved. Only conservatively managed horses with follow-up information were included. Follow-up information on clinical outcome was retrieved from the medical records (n=11) or obtained by telephone interviews with the owners or trainers (n=13). Twenty-three horses (96%) returned to their previous or intended use and had no clinically evident masticatory or fracture healing-related problems at the time of follow-up. The owner of 1 horse (4%) reported it had tooth loosening, feed impaction, and masticatory problems. Conservative management of unilateral fractures of the mandibular rami is a treatment option in horses. © Copyright 2016 by The American College of Veterinary Surgeons.

2017-12-01

Equine viral arteritis (EVA) may have a high economic impact on breeding stud farms due to the occurrence of EVA-associated abortion outbreaks and the ability of the virus to persist in carrier stallions. While the consequences of EVA in premises with sport horses are usually less severe, the first confirmed outbreak of EVA in Spain occurred in a riding club in Barcelona, but no data on the seroprevalence of EVA in sport horses have been reported in Spain. Given the importance of both Spanish Purebred (SP) breeding horses and sport horses for Spain's equine industry, the aim of this study was to determine and compare the seroprevalence of EVA in these two horse populations in central Spain. Serum samples from 155 SP breeding horses residing in 16 stud farms and 105 sport horses of different breeds housed in 12 riding clubs, collected between September 2011 and November 2013, were tested using a commercial EVA antibody ELISA test with a 100% sensitivity, and confirmed by seroneutralisation (SN) test. EVA seroprevalence in SP breeding horses was higher 21.1% (95% CI 15.3-26.8%) than that in sport horses (6.7%, 95% CI 1.89-11.45%). However, the primary use (breeding vs. sport) was not significantly associated with seropositivity to Equine Arteritis Virus (EAV), suggesting that different management factors do not affect EVA circulation in these two horse populations.

Equine herpesvirus type 1 (EHV-1) is the cause of respiratory disease, abortion storms, and outbreaks of herpesvirus myeloencephalopathy (EHM). Infection of the spinal cord is characterised by multifocal regions of virally infected vascular endothelium, associated with vasculitis, thrombosis and haemorrhage that result in ischaemia and organ dysfunction. However, the mechanism of thrombosis in affected horses is unknown. To evaluate tissue factor (TF) procoagulant activity and thrombin-antithrombin complex (TAT) levels in horses following infection with EHV-1. In vitro and in vivo studies following experimental EHV-1 infection. Horses were infected with EHV-1 and levels of peripheral blood mononuclear cell (PBMC)-associated TF activity; plasma and cerebrospinal fluid (CSF)-derived microvesicle (MV)-associated TF activity and TAT complexes in plasma were examined. EHV-1 infection increased PBMC TF procoagulant activity in vitro and in vivo. In infected horses, this increase was observed during the acute infection and was most marked at the onset and end of viraemia. However, no significant differences were observed between the horses that showed signs of EHM and the horses that did not develop EHM. Significant changes in MV-associated TF procoagulant activity and TAT complexes were not observed in infected horses. A small number of horses typically exhibit clinical EHM following experimental infection. The results indicate that EHV-1 infection increases PBMC-associated TF procoagulant activity in vivo and in vitro. Additional in vivo studies are needed to better understand the role of TF-dependent coagulation during EHM pathogenesis in horses. © 2018 EVJ Ltd.

Equine protozoal myeloencephalitis is a progressive neurologic disease of horses most commonly caused by infection with the apicomplexan parasite Sarcocystis neurona. Factors affecting neuroinvasion and neurovirulence have not been determined. We investigated the pathogenesis of infection with S. neurona in horses with severe combined immune deficiency (SCID). Two immunocompetent (IC) Arabian horses and two Arabian horses with SCID were infected orally with 5 x 10(5) sporocysts of S. neurona. Four IC horses and one SCID horse were infected intravenously (i.v.) with 5 x 10(8) merozoites of the WSU-1 isolate of S. neurona. Despite prolonged parasitemia and persistent infection of visceral tissues (skeletal muscle, cardiac muscle, lung, liver, and spleen) as demonstrated by PCR and culture, SCID horses did not develop neurologic signs after oral or i.v. infection. S. neurona was undetectable in the neuronal tissues of SCID horses by either PCR, immunohistochemistry, or culture. In contrast, although parasitemia was undetectable in orally infected IC horses and of only short duration in i.v. infected IC horses, four of six IC horses developed neurologic signs. S. neurona was detectable by PCR and/or culture of neural tissue but not visceral tissue of IC horses with neurologic disease. Infected SCID horses are unable to clear S. neurona from visceral tissues, but the infection does not result in neurologic signs; in contrast, IC horses rapidly control parasitemia and infection of visceral tissues but frequently experience neuroinvasion and exhibit clinical signs of neurologic disease.

Glucocorticoids and laminitis in the horse.

Johnson, Philip J; Slight, Simon H; Ganjam, Venkataseshu K; Kreeger, John M

2002-08-01

The administration of exogenously administered GCs and syndromes associated with GC excess are both attended by increased risk for the development of laminitis in adult horses. However, there exists substantial controversy as to whether excess GCs cause laminitis de novo. If true, the pathogenesis of laminitis arising from the effects of GC excess is probably different from that associated with diseases of the gastrointestinal tract and endotoxemia. Although a satisfactory explanation for the development of laminitis as a consequence of GC action is currently lacking, numerous possible and plausible theoretical mechanisms do exist. Veterinarians must exert caution with respect to the use of GCs in adult horses. The extent to which individual horses are predisposed to laminitis as a result of GC effect cannot be predicted based on current information. However, the administration of systemic GCs to horses that have been previously affected by laminitis should be used only with extreme caution, and should be accompanied by careful monitoring for further signs of laminitis. The risk of laminitis appears to be greater during treatment using some GCs (especially dexamethasone and triamcinalone) compared with others (prednisone and prednisolone). Whenever possible, to reduce the risk of laminitis, GCs should be administered locally. For example, the risk of GC-associated laminitis is evidently considerably reduced in horses affected with chronic obstructive pulmonary disease (COPD) if GC treatment is administered via inhalation. We have hypothesized that structural changes in the equine hoof that resemble laminitis may arise as a consequence of excess GC effect. Although these changes are not painful per se, and are not associated with inflammation, they could likely predispose affected horses to the development of bona fide laminitis for other reasons. Moreover, the gross morphological appearance of the chronically GC-affected hoof resembles that of a chronically

Portions of heart, liver, skeletal and diaphragmatic muscles obtained from 150 slaughtered horses at Giza-Zoo abattoir were used for bioassays in mice and cats. T. gondii tachyzoites were isolated successfully from the peritoneal exudates of the inoculated mice 6-8 days post inoculation with pooled horse tissues. Whereas, T. gondii tissue cysts containing bradyzoites were detected in the impression smears of mice brain on the 45th days or more post infection. The oocysts were detected in feces of cats 3-6 days post feeding on horse tissues containing tissue cysts. The oocysts became sporulated within 3-5 days in 2.5% Potassium dichromate. A total of 79 out of 150 horse meat samples were found to be infected with an incidence rate of 52.6 %. This is the first trial for isolation of T. gondii infective stages from horses in Egypt. Moreover, this study pointed out to the high infection rate of T. gondii in horse meat which may be considered as an important source of infection to wild zoo-animals in Egypt and humans in some countries if consumed raw or insufficiently cooked.

Horse manure as feedstock for anaerobic digestion.

Science.gov (United States)

Hadin, Sa; Eriksson, Ola

2016-10-01

Horse keeping is of great economic, social and environmental benefit for society, but causes environmental impacts throughout the whole chain from feed production to manure treatment. According to national statistics, the number of horses in Sweden is continually increasing and is currently approximately 360,000. This in turn leads to increasing amounts of horse manure that have to be managed and treated. Current practices could cause local and global environmental impacts due to poor performance or lack of proper management. Horse manure with its content of nutrients and organic material can however contribute to fertilisation of arable land and recovery of renewable energy following anaerobic digestion. At present anaerobic digestion of horse manure is not a common treatment. In this paper the potential for producing biogas and biofertiliser from horse manure is analysed based on a thorough literature review in combination with mathematical modelling and simulations. Anaerobic digestion was chosen as it has a high degree of resource conservation, both in terms of energy (biogas) and nutrients (digestate). Important factors regarding manure characteristics and operating factors in the biogas plant are identified. Two crucial factors are the type and amount of bedding material used, which has strong implications for feedstock characteristics, and the type of digestion method applied (dry or wet process). Straw and waste paper are identified as the best materials in an energy point of view. While the specific methane yield decreases with a high amount of bedding, the bedding material still makes a positive contribution to the energy balance. Thermophilic digestion increases the methane generation rate and yield, compared with mesophilic digestion, but the total effect is negligible. Copyright © 2016. Published by Elsevier Ltd.

Combined active-passive immunisation of horses against tetanus.

Science.gov (United States)

Liefman, C E

1980-03-01

The protection afforded by active, passive and combined active-passive methods of immunisation against tetanus was examined in previously unimmunised horses. Three groups of horses were injected; one with tetanus toxoid alone, one with tetanus antitoxin alone and one in which the tetanus toxoid and tetanus antitoxin were injected simultaneously. The protection afforded was determined by monitoring the levels of antitoxin achieved in the horses by each of these methods. The results obtained demonstrated the effectiveness of the combined active-passive method in affording rapid and prolonged protection and enabled the examination of some of the factors involved in active and in passive immunisation when used alone. The advantages obtained by the use of the combined active-passive method in protecting unimmunised horses suddenly placed at risk to infection are outlined.

Equine coronaviruses (ECoV) are the only coronavirus known to infect horses. So far, data on ECoV infection in horses remain limited to the USA, France and Japan and its geographic distribution is not well understood. We carried out RT-PCR on 306 nasal and 315 rectal swabs and tested 243 sera for antibodies to detect coronavirus infections in apparently healthy horses in Saudi Arabia and Oman. We document evidence of infection with ECoV and HKU23 coronavirus by RT-PCR. There was no conclusive evidence of Middle East respiratory syndrome coronavirus infection in horses. Serological data suggest that lineage A betacoronavirus infections are commonly infecting horses in Saudi Arabia and Oman but antibody cross-reactivities between these viruses do not permit us to use serological data alone to identify which coronaviruses are causing these infections. © 2017 Blackwell Verlag GmbH.

Is shade for horses a comfort resource or a minimum requirement?

Science.gov (United States)

Holcomb, K E

2017-09-01

Shade or shelter as protection from extremes of weather is required for horses at agricultural research and teaching facilities and is recommended or required by many states, professional organizations, and industry groups. The focus of this paper is the recent research on the responses of horses to hot, sunny weather, which has begun to provide scientific evidence that characterizes how and when shade is used and any benefits shade confers on horses. These behavioral and physiological findings support provision of shade as a resource for thermal comfort and the expression of normal behavior that should be included as a standard of best care practices for healthy adult horses living in the environmental conditions reviewed, rather than an absolute minimum care requirement. Additional research is required for horses living under other environmental conditions, for very young or old horses, horses in very poor body condition, or those with compromised health to determine if their responses to hot, sunny weather differ from those presented here.

Concentrations of the cross-linked carboxyterminal telopeptide of type I collagen (ICTP) and osteocalcin (OC) have been determined in the serum of one hundred clinically healthy adult Draught or Warmblood horses. The correlation between these two markers has been evaluated and the influence of gender, age and type of horse described. No significant variations were observed between animals of different sex, but a significant inverse correlation (P Draught [adjusted least square mean (LSM) = 6.612 micrograms.L-1] than in Warmblood horses (adjusted LSM = 8.596 micrograms.L-1), whereas levels of ICTP were higher in Draughts (adjusted LSM = 8.035 micrograms.L-1) than in Warmbloods (adjusted LSM = 6.643 micrograms.L-1). A significant correlation (P Draught horses might reflect a higher bone remodelling level of horses submitted to regular daily work. It was concluded that ICTP and OC are influenced by the type of horse, and probably reflect a physiological difference in bone remodelling between these animals.

Welfare, Quality of Life, and Euthanasia of Aged Horses.

McGowan, Catherine M; Ireland, Joanne L

Duration of ownership strengthens the human-horse bond, affecting decision-making about the horse's welfare, quality of life (QoL), and euthanasia. Most owners consider their geriatric horses to have good or excellent QoL; however, increasing age is negatively associated with QoL. Management factors are important. The most common reasons for euthanasia include musculoskeletal disorders or lameness, colic, and nonspecific chronic diseases. The decision to euthanize is difficult, so the advice of the veterinarian and QoL are important. This article focuses on the human-horse bond, assessment of QoL, reasons for euthanasia, and owner experiences of mortality. Copyright © 2016 Elsevier Inc. All rights reserved.

The domestic horse is the most widely used and important stock and recreational animal, valued for its strength and endurance. The energy required by the domestic horse is mainly supplied by mitochondria via oxidative phosphorylation. Thus, selection may have played an essential role in the evolution of the horse mitochondria. Besides, demographic events also affect the DNA polymorphic pattern on mitochondria. To understand the evolutionary patterns of the mitochondria of the domestic horse, we used a deep sequencing approach to obtain the complete sequences of 15 mitochondrial genomes, and four mitochondrial gene sequences, ND6, ATP8, ATP6 and CYTB, collected from 509, 363, 363 and 409 domestic horses, respectively. Evidence of strong substitution rate heterogeneity was found at nonsynonymous sites across the genomes. Signatures of recent positive selection on mtDNA of domestic horse were detected. Specifically, five amino acids in the four mitochondrial genes were identified as the targets of positive selection. Coalescentbased simulations imply that recent population expansion is the most probable explanation for the matrilineal population history for domestic horse. Our findings reveal a complex pattern of non-neutral evolution of the mitochondrial genome in the domestic horses.

Review of hypoxaemia in anaesthetized horses: predisposing factors, consequences and management.

Science.gov (United States)

Auckburally, Adam; Nyman, Görel

2017-05-01

To discuss how hypoxaemia might be harmful and why horses are particularly predisposed to developing it, to review the strategies that are used to manage hypoxaemia in anaesthetized horses, and to describe how successful these strategies are and the adverse effects associated with them. Google Scholar and PubMed, using the search terms horse, pony, exercise, anaesthesia, hypoxaemia, oxygen, mortality, morbidity and ventilation perfusion mismatch. Although there is no evidence that hypoxaemia is associated with increased morbidity and mortality in anaesthetized horses, most anaesthetists would agree that it is important to recognise and prevent or treat it. Favourable anatomical and physiological adaptations of a horse for exercise adversely affect gas exchange once the animal is recumbent. Hypoxaemia is recognised more frequently in horses than in other domestic species during general anaesthesia, although its incidence in healthy horses remains unreported. Management of hypoxaemia in anaesthetized horses is challenging and often unsuccessful. Positive pressure ventilation strategies to address alveolar atelectasis in humans have been modified for implementation in recumbent anaesthetized horses, but are often accompanied by unpredictable and unacceptable cardiopulmonary adverse effects, and some strategies are difficult or impossible to achieve in adult horses. Furthermore, anticipated beneficial effects of these techniques are inconsistent. Increasing the inspired fraction of oxygen during anaesthesia is often unsuccessful since much of the impairment in gas exchange is a direct result of shunt. Alternative approaches to the problem involve manipulation of pulmonary blood away from atelectatic regions of the lung to better ventilated areas. However, further work is essential, with particular focus on survival associated with general anaesthesia in horses, before any technique can be accepted into widespread clinical use.

Do horses with poor welfare show `pessimistic' cognitive biases?

Science.gov (United States)

Henry, S.; Fureix, C.; Rowberry, R.; Bateson, M.; Hausberger, M.

2017-02-01

This field study tested the hypothesis that domestic horses living under putatively challenging-to-welfare conditions (for example involving social, spatial, feeding constraints) would present signs of poor welfare and co-occurring pessimistic judgement biases. Our subjects were 34 horses who had been housed for over 3 years in either restricted riding school situations ( e.g. kept in single boxes, with limited roughage, ridden by inexperienced riders; N = 25) or under more naturalistic conditions ( e.g. access to free-range, kept in stable social groups, leisure riding; N = 9). The horses' welfare was assessed by recording health-related, behavioural and postural indicators. Additionally, after learning a location task to discriminate a bucket containing either edible food (`positive' location) or unpalatable food (`negative' location), the horses were presented with a bucket located near the positive position, near the negative position and halfway between the positive and negative positions to assess their judgement biases. The riding school horses displayed the highest levels of behavioural and health-related problems and a pessimistic judgment bias, whereas the horses living under more naturalistic conditions displayed indications of good welfare and an optimistic bias. Moreover, pessimistic bias data strongly correlated with poor welfare data. This suggests that a lowered mood impacts a non-human species' perception of its environment and highlights cognitive biases as an appropriate tool to assess the impact of chronic living conditions on horse welfare.

Mizukami, Takuya; Abe, Yukiko; Maki, Kosuke

2015-01-01

In this study, the equivalence of the kinetic mechanisms of the formation of urea-induced kinetic folding intermediates and non-native equilibrium states was investigated in apomyoglobin. Despite having similar structural properties, equilibrium and kinetic intermediates accumulate under different conditions and via different mechanisms, and it remains unknown whether their formation involves shared or distinct kinetic mechanisms. To investigate the potential mechanisms of formation, the refolding and unfolding kinetics of horse apomyoglobin were measured by continuous- and stopped-flow fluorescence over a time range from approximately 100 μs to 10 s, along with equilibrium unfolding transitions, as a function of urea concentration at pH 6.0 and 8°C. The formation of a kinetic intermediate was observed over a wider range of urea concentrations (0–2.2 M) than the formation of the native state (0–1.6 M). Additionally, the kinetic intermediate remained populated as the predominant equilibrium state under conditions where the native and unfolded states were unstable (at ~0.7–2 M urea). A continuous shift from the kinetic to the equilibrium intermediate was observed as urea concentrations increased from 0 M to ~2 M, which indicates that these states share a common kinetic folding mechanism. This finding supports the conclusion that these intermediates are equivalent. Our results in turn suggest that the regions of the protein that resist denaturant perturbations form during the earlier stages of folding, which further supports the structural equivalence of transient and equilibrium intermediates. An additional folding intermediate accumulated within ~140 μs of refolding and an unfolding intermediate accumulated in <1 ms of unfolding. Finally, by using quantitative modeling, we showed that a five-state sequential scheme appropriately describes the folding mechanism of horse apomyoglobin. PMID:26244984

Endotoxemia models are used to study mechanisms and treatments of early sepsis. Repeated endotoxin exposures induce periods of endotoxin tolerance, characterized by diminished proinflammatory responses to lipopolysaccharide (LPS) and modulated production of proinflammatory cytokines. Repeated measure designs using equine endotoxemia models are rarely performed, despite the advantages associated with reduced variability, because the altered responsiveness would confound study results and because the duration of equine endotoxin tolerance is unknown. We determined the interval of endotoxin tolerance, in vivo, in horses based on physical, clinicopathologic, and proinflammatory gene expression responses to repeated endotoxin exposures. Six horses received 30 ng/kg LPS in saline infused over 30 min. Behavior pain scores, physical examination parameters, and blood for complete blood count and proinflammatory gene expression were obtained at predetermined intervals for 24h. Horses received a total of 3 endotoxin exposures. The first exposure was LPS 1, followed 7 days later by LPS 7 or 14-21 days later by LPS 14-21. Lipopolysaccharide exposures were allocated in a randomized, crossover design. Lipopolysaccharide produced clinical and clinicopathologic signs of endotoxemia and increased expression of tumor necrosis factor alpha (TNFα), interleukin (IL)-6 and IL-8, PHorses exhibited evidence of endotoxin tolerance following LPS 7 but not following LPS 14-21. Horses had significantly lower pain scores, heart rates, respiratory rates and duration of fever, after LPS 7 compared to LPS 1 and LPS 14-21, Phorses after LPS 7, P=0.05. Clinical parameters and TNFα gene expression were similar or slightly increased in horses following LPS 14-21 compared to measurements made in horses following LPS 1, suggesting that endotoxin tolerance had subsided. A minimum of 3 weeks between experiments is warranted if repeated measures designs are used to assess in vivo response to endotoxin in

Dietary change and evolution of horses in North America.

2011-03-04

The evolution of high-crowned molars among horses (Family Equidae) is thought to be an adaptation for abrasive diets associated with the spread of grasslands. The sharpness and relief of the worn cusp apices of teeth (mesowear) are a measure of dietary abrasion. We collected mesowear data for North American Equidae for the past 55.5 million years to test the association of molar height and dietary abrasion. Mesowear trends in horses are reflective of global cooling and associated vegetation changes. There is a strong correlation between mesowear and crown height in horses; however, most horse paleopopulations had highly variable amounts of dietary abrasion, suggesting that selective pressures for crown height may have been weak much of the time. However, instances of higher abrasion were observed in some paleopopulations, suggesting intervals of stronger selection for the evolution of dentitions, including the early Miocene shortly before the first appearance of Equinae, the horse subfamily in which high-crowned dentitions evolved.

2016-08-01

We present a study focused on a quantitative estimation of a human-horse dynamic interaction. A set of measures based on magnitude and phase coupling between heartbeat dynamics of both humans and horses in three different conditions is reported: no interaction, visual/olfactory interaction and grooming. Specifically, Magnitude Squared Coherence (MSC), Mean Phase Coherence (MPC) and Dynamic Time Warping (DTW) have been used as estimators of the amount of coupling between human and horse through the analysis of their heart rate variability (HRV) time series in a group of eleven human subjects, and one horse. The rationale behind this study is that the interaction of two complex biological systems go towards a coupling process whose dynamical evolution is modulated by the kind and time duration of the interaction itself. We achieved a congruent and consistent statistical significant difference for all of the three indices. Moreover, a Nearest Mean Classifier was able to recognize the three classes of interaction with an accuracy greater than 70%. Although preliminary, these encouraging results allow a discrimination of three distinct phases in a real human-animal interaction opening to the characterization of the empirically proven relationship between human and horse.

Nuclear scintigraphic evaluation of third metacarpal and metatarsal bone fractures in three horses

International Nuclear Information System (INIS)

Markel, M.D.; Snyder, J.R.; Hornof, W.J.; Meagher, D.M.

1987-01-01

Nuclear scintigraphy was used to evaluate healing of third metacarpal bone (MC III) fractures in 2 horses (horses 1 and 2) and a third metatarsal bone fracture in 1 horse (horse 3) after stabilization of each fracture with 2 broad dynamic compression plates. In horse 1, the fracture had uniform uptake of 99mTc methylene diphosphonate on days 1, 15, and 30 after surgery. The fracture healed, and the horse was discharged from the clinic on day 52. In horse 2, a 6-cm photopenic region (ie, area of low radioactivity) was seen over the diaphysis of MC III on day 3. The region persisted and became more distinct by day 32. The diaphysis of MC III sequestered, and horse 2 was euthanatized on day 44. In horse 3, vascularity was seen bridging the fracture on day 5, with a 3-cm photopenic region over the dorsal diaphysis of the third metatarsal bone. By days 18 and 32, uptake of 99mTc methylene diphosphonate in the region had increased, indicating vascularization of the site. the fracture healed, and horse 3 was discharged from the clinic on day 47. Our findings indicated that serial nuclear scintigraphy can be used to evaluate fracture vascularization after surgery in horses

Brainstem auditory evoked response has been an underused diagnostic modality in horses as evidenced by few reports on the subject. To describe BAER findings, common clinical signs, and causes of hearing loss in adult horses. Study group, 76 horses; control group, 8 horses. Retrospective. BAER records from the Clinical Neurophysiology Laboratory were reviewed from the years of 1982 to 2013. Peak latencies, amplitudes, and interpeak intervals were measured when visible. Horses were grouped under disease categories. Descriptive statistics and a posthoc Bonferroni test were performed. Fifty-seven of 76 horses had BAER deficits. There was no breed or sex predisposition, with the exception of American Paint horses diagnosed with congenital sensorineural deafness. Eighty-six percent (n = 49/57) of the horses were younger than 16 years of age. The most common causes of BAER abnormalities were temporohyoid osteoarthropathy (THO, n = 20/20; abnormalities/total), congenital sensorineural deafness in Paint horses (17/17), multifocal brain disease (13/16), and otitis media/interna (4/4). Auditory loss was bilateral and unilateral in 74% (n = 42/57) and 26% (n = 15/57) of the horses, respectively. The most common causes of bilateral auditory loss were sensorineural deafness, THO, and multifocal brain disease whereas THO and otitis were the most common causes of unilateral deficits. Auditory deficits should be investigated in horses with altered behavior, THO, multifocal brain disease, otitis, and in horses with certain coat and eye color patterns. BAER testing is an objective and noninvasive diagnostic modality to assess auditory function in horses. Copyright © 2014 by the American College of Veterinary Internal Medicine.

To determine major causes of death and the anatomic location of musculoskeletal injuries in Quarter Horse racehorses in California. Retrospective case series. 314 Quarter Horse racehorses with musculoskeletal injuries that were necropsied through the California Horse Racing Board Postmortem Program from 1990 to 2007. Postmortem pathology reports were retrospectively reviewed. Musculoskeletal injuries were categorized by anatomic region and described. The number of Quarter Horse starts and starters for the same period of time were obtained from a commercial database for determination of fatal injury incidence. Musculoskeletal injuries accounted for 314 of the 443 (71 %) Quarter Horse racehorses that died during the 18-year study period. Fatal musculoskeletal injuries occurred at a rate of 2.0 deaths/1,000 race starts and 18.6 deaths/1,000 horses that started a race. Musculoskeletal injuries occurred predominantly during racing (84%) and in the forelimbs (81%). The most common fatal musculoskeletal injuries were metacarpophalangeal and metatarsophalangeal joint (fetlock) support injuries (40%) and carpal (24%), vertebral (10%), and scapular (8%) fractures. Proximal interphalangeal (pastern) joint luxations resulted in death of 3% of horses. Fracture configurations of some bones were consistent with those of Thoroughbred racehorses. Evidence of preexisting stress remodeling of bone was reported for some fractures. Knowledge of common locations and types of fatal musculoskeletal injuries in racing Quarter Horses may enhance practitioners' ability to detect mild injuries early, rest horses, and help prevent catastrophic injuries.

EFFECTS OF TRANSPORTATION STRESS ON SOME PHYSIOLOGICAL INDICATORS IN SPORT HORSES

Directory of Open Access Journals (Sweden)

IOANA ANDRONIE

2009-10-01

Full Text Available Our research monitored the response of some welfare indicators in sport horses during transport by assessing the intensity of stress during travel time, changes in heart rate, cortisol, lactic acid and creatinine levels. The horses included in the study were separated into 2 groups: horses that were transported for the first time (A n: 12 and horses that had been previously transported (B n: 10. The values of the indicators varied between the two groups regardless of the fact that travel length and transport conditions were almost identical. The heart rate and cortisol levels were elevated in horses from group A as compared to the ones in group B while the latter showed increased levels of these indicators upon repeating the loading and unloading (100-130 nmol/l. The recorded value of lactic acid was higher for the first group (2,2 mmol/l, only until the moment when the horses adapted to the effort, after which it decreased (1,8 mmol/l. Transport of horses under certain conditions related to their adjusting to manhandling during loading and unloading operations, as well as the animals’ temper, may be considered a stress factor with significant depreciating effect on horse welfare.

Komosa, M; Frackowiak, H; Purzyc, H; Wojnowska, M; Gramacki, A; Gramacki, J

2013-04-01

The study included 249 horses belonging to 3 horse breeds. Konik horses, comprising the first group, is an example of a breed similar to the extinct Tarpan. In our study, these horses were taken to be a primitive anatomical model of the horse body. The other groups comprised the Polish Half-bred horse and Thoroughbred horse. The biometric characteristics of the horses were compared based on 24 indices. The aim of the paper was to find a reduced set of indices that can be used to determine group membership of the horses. To do this, we used statistical methods to find the most important indices that best discriminate breeds from each other. Chi-squared statistics, linear discriminant analysis, logistic regression, and 1-way ANOVA showed that the discrimination among groups of horses is connected with these 5 indices: scapula, smaller trunk (distance between tubercle of humerus and coxal tuber), greater trunk (distance between tubercle of humerus and ischial tuberosity), metacarpus circumference, and hind autopodium-smaller trunk. Thoroughbred and Half-bred horses are clearly different in exterior conformation from Konik horses. The differences between Thoroughbred and Half-bred horses are more subtle. The conformation of Thoroughbreds is jointly determined by relatively small differences in a range of features.

2016-10-01

Methocarbamol (MCBL) is commonly used in performance horses for the treatment of skeletal muscle disorders. Current regulatory recommendations for show horses and racehorses are based on a single oral dose of 5 g, although doses in excess of this are often administered. The goal of the current study was to characterize the disposition of MCBL following higher dose administration and administration in combination with another commonly used drug in performance horses, phenylbutazone (PBZ). Exercised Thoroughbred horses were administered various doses of MCBL as a sole agent and MCBL in combination with PBZ. Blood samples were collected at various times, concentrations of MCBL and PBZ measured using LC-MS/MS and pharmacokinetic parameters calculated using compartmental analysis. Following administration of 15 g of MCBL, either as part of a single- or multiple-dose regimen, a number of horses exceeded the Association of Racing Commissioners International and the United States Equestrian Federation's recommended regulatory threshold at the recommended withdrawal time. There was not a significant difference between horses that received only MCBL and those that received MCBL and PBZ. Results of the current study support an extended withdrawal guideline when doses in excess of 5 g are administered. © 2016 John Wiley & Sons Ltd.

The ability of horses to learn through social observation may ease the implementation of new management systems, because the use of automatic feeders etc. by naive horses could be facilitated by observation of experienced horses. However, previous studies found no documentation for observational...... in ten successive demonstrations, where a trained Demonstrator opened an operant device by pushing a sliding lid aside with the muzzle in order to obtain a food reward. Immediately after the demonstrations the Observer horses were given the opportunity to operate the device alone. Control horses (n = 11.......15). Analysis of investigative behaviour showed, however, that the demonstrations increased the motivation of the Observer horses to investigate the device. Subsequently, a similar experiment was performed in a practical setting with 44 test horses (mixed age, gender and breed). We used the same operant device...

2015-01-15

A cross-sectional survey was performed to obtain current data on the gastrointestinal myiasis of horses in the provinces of Kostanay, Akmola and Karagandy, northern and central Kazakhstan. The stomach, small intestine and rectum of 148 slaughter horses were examined for Gasterophilus spp. larvae during a 26-month study period. All horses were infected with 2nd and 3rd stage larvae (mean intensity: 803±350), and 22% of them harboured >1000 Gasterophilus spp. larvae each. Four species were identified: G. intestinalis (prevalence: 100%; mean intensity: 361±240 larvae), G. haemorrhoidalis (100%; 353±191), G. nasalis (100%; 73±36) and G. pecorum (91.2%; 18±10). Horses aged<2 years were higher infected with Gasterophilus larvae than 2-4 years old animals. Both the prevalence and extremely high intensity of Gasterophilus infections of horses in these Kazakh regions suggest respective control measurements to improve the health and performance of the animals and to increase the economic income of horse owners.

The rich fossil record of equids has made them a model for evolutionary processes. Here we present a 1.12-times coverage draft genome from a horse bone recovered from permafrost dated to approximately 560-780 thousand years before present (kyr BP). Our data represent the oldest full genome sequence determined so far by almost an order of magnitude. For comparison, we sequenced the genome of a Late Pleistocene horse (43 kyr BP), and modern genomes of five domestic horse breeds (Equus ferus caballus), a Przewalski's horse (E. f. przewalskii) and a donkey (E. asinus). Our analyses suggest that the Equus lineage giving rise to all contemporary horses, zebras and donkeys originated 4.0-4.5 million years before present (Myr BP), twice the conventionally accepted time to the most recent common ancestor of the genus Equus. We also find that horse population size fluctuated multiple times over the past 2 Myr, particularly during periods of severe climatic changes. We estimate that the Przewalski's and domestic horse populations diverged 38-72 kyr BP, and find no evidence of recent admixture between the domestic horse breeds and the Przewalski's horse investigated. This supports the contention that Przewalski's horses represent the last surviving wild horse population. We find similar levels of genetic variation among Przewalski's and domestic populations, indicating that the former are genetically viable and worthy of conservation efforts. We also find evidence for continuous selection on the immune system and olfaction throughout horse evolution. Finally, we identify 29 genomic regions among horse breeds that deviate from neutrality and show low levels of genetic variation compared to the Przewalski's horse. Such regions could correspond to loci selected early during domestication.

Native fruit traits may mediate dispersal competition between native and non-native plants

Full Text Available Seed disperser preferences may mediate the impact of invasive, non-native plant species on their new ecological communities. Significant seed disperser preference for invasives over native species could facilitate the spread of the invasives while impeding native plant dispersal. Such competition for dispersers could negatively impact the fitness of some native plants. Here, we review published literature to identify circumstances under which preference for non-native fruits occurs. The importance of fruit attraction is underscored by several studies demonstrating that invasive, fleshy-fruited plant species are particularly attractive to regional frugivores. A small set of studies directly compare frugivore preference for native vs. invasive species, and we find that different designs and goals within such studies frequently yield contrasting results. When similar native and non-native plant species have been compared, frugivores have tended to show preference for the non-natives. This preference appears to stem from enhanced feeding efficiency or accessibility associated with the non-native fruits. On the other hand, studies examining preference within existing suites of co-occurring species, with no attempt to maximize fruit similarity, show mixed results, with frugivores in most cases acting opportunistically or preferring native species. A simple, exploratory meta-analysis finds significant preference for native species when these studies are examined as a group. We illustrate the contrasting findings typical of these two approaches with results from two small-scale aviary experiments we conducted to determine preference by frugivorous bird species in northern California. In these case studies, native birds preferred the native fruit species as long as it was dissimilar from non-native fruits, while non-native European starlings preferred non-native fruit. However, native birds showed slight, non-significant preference for non-native fruit

Full Text Available Abstract Background Many people spend considerable amount of time each day in equine stable environments either as employees in the care and training of horses or in leisure activity. However, there are few studies available on how the stable environment affects human airways. This study examined in one horse stable qualitative differences in indoor air during winter and late summer conditions and assessed whether air quality was associated with clinically detectable respiratory signs or alterations to selected biomarkers of inflammation and lung function in stable personnel. Methods The horse stable environment and stable-workers (n = 13 in one stable were investigated three times; first in the winter, second in the interjacent late summer and the third time in the following winter stabling period. The stable measurements included levels of ammonia, hydrogen sulphide, total and respirable dust, airborne horse allergen, microorganisms, endotoxin and glucan. The stable-workers completed a questionnaire on respiratory symptoms, underwent nasal lavage with subsequent analysis of inflammation markers, and performed repeated measurements of pulmonary function. Results Measurements in the horse stable showed low organic dust levels and high horse allergen levels. Increased viable level of fungi in the air indicated a growing source in the stable. Air particle load as well as 1,3-β-glucan was higher at the two winter time-points, whereas endotoxin levels were higher at the summer time-point. Two stable-workers showed signs of bronchial obstruction with increased PEF-variability, increased inflammation biomarkers relating to reported allergy, cold or smoking and reported partly work-related symptoms.

Rahvusliku ajaloo tõlgendusi eesti draamas ja teatris 1970.–1980. aastatel. Interpretations of National History in Estonian Drama and Theatre in the 1970s–1980s

Full Text Available According to theatre scholar Freddie Rokem, theatre portraying or performing historical events is seeking to overcome both the separation and the exclusion from the past, as well as ’striving to create a community where the events from this past will matter again’. This article covers the topic of interpretations of national history in Estonian theatre and in original dramaturgy during the Soviet era, with the focus on aspects like national self-reflection and the relationship to the common past. The main focus is on the 1970s, with examples from Rein Saluri’s, Mati Unt’s and Jaan Kaplinski’s drama productions. During the period in question, re-tellings of national history on Estonian theatre stages were clothed in metaphors, allusions and secret codes – Aesopian language. Within the Soviet cultural context, I analyse if and to what extent theatre of the time displayed resistance, political theatre or social allegory. Theatre was also connected with the principle of playing or playfulness, which on one hand indicates national resistance, national endurance, and a certain survival strategy, but on the other hand indicates the Estonian as being an involuntary homo ludens – the Playing Man, who through various enforced roles is trying to adjust to the whirlwinds of history. Saluri’s first play, the intellectual drama Külalised (The Guests, opens with an allusion to a drama classic the world over, William Shakespeare’s Hamlet, adding a powerful national-symbolic background to the play. The role-play which permeates and structures the play (The Host–The Guest however, displays allegorical references to changes in the status and self-image of Estonians. In Unt’s play Peaproov (Dress Rehearsal, the principle of playing/acting sheds ironic light on the makers of an historical film and their readiness to create superficially flashy interpretations at any cost: this take acts as an estranging and generalising reflection in a context

As stated in the Wild Horse Fertility Control Field Trial Plan, the Bureau of Land Management (BLM) has an immediate need for a safe, effective contraceptive agent to assist in the management of the large number of wild horses on western rangelands. The BLM and the U.S. Geological Survey-Biological Resources Discipline (USGS/BRD) are testing the immunocontraceptive agent Porcine Zonae Pellucida (PZP) in field trials with three free-roaming herds of western wild horses. Extensive research has already been conducted on the safety, efficacy, and duration of PZP applications in both domestic and feral horses on eastern barrier islands and in some select trials I with wild horses in Nevada managed by the BLM. However, significant questions remain concerning the effects of I PZP application at the population level in the wild, as well as effects at the individual level on behavior, social structure, and harem dynamics of free-ranging animals. These questions are best answered with field trials on wild horse herds under a tight research protocol. The ultimate goal is to provide the BLM with the protocols and information necessary to begin using fertility control to regulate population growth rates in wild horse herds on a broader scale. Fertility control is intended to assist the conventional capture, removal, and adoption process as a I means of controlling excess numbers of wild horses and burros, and to greatly reduce the adoption costs and numbers of animals handled. Fertility control is not intended to totally replace the removal and adoption process.

Ingestion of wilted red maple leaves by horses can result in severe hemolytic anemia and methemoglobinemia. Little is known about what factors influence the outcome of red maple leaf toxicosis in horses. Our hypothesis was that physical examination findings, clinicopathologic variables or therapeutic modalities may predict outcome in horses with red maple leaf toxicity. Horses with red maple leaf toxicosis presented to referral hospitals in the southeast region of the United States. A multi-institutional retrospective study was designed to identify factors that predict mortality in horses with red maple toxicosis. Thirty-two horses with red maple toxicosis were identified, 19 of which died. Twenty-nine horses presented with anemia and 24 had clinicopathologic evidence of systemic inflammation. Renal insufficiency was identified in 12/30 (41%) horses. Laminitis (9/28) and colic (13/30) also were identified in horses with red maple toxicosis, but development of these 2 conditions did not have a negative effect on short-term survival. Horses with red maple toxicosis that survived to discharge were likely to have developed pyrexia during hospitalization (P = .030). Horses that were treated with a corticosteroid had a significantly increased likelihood of death (P = .045). There was no significant relationship between initial serum hemoglobin concentration, methemoglobin concentration, or percentage methemoglobin and mortality in this horse series. This study suggests that information obtained on initial examination cannot be used to accurately predict survival in horses with red maple toxicosis, but horses that receive corticosteroids are unlikely to survive.

The effects of age, rank and neophobia on social learning in horses.

Social learning is said to meet the demands of complex environments in which individuals compete over resources and cooperate to share resources. Horses (Equus caballus) were thought to lack social learning skills because they feed on homogenously distributed resources with few reasons for conflict. However, the horse's social environment is complex, which raises the possibility that its capacity for social transfer of feeding behaviour has been underestimated. We conducted a social learning experiment using 30 socially kept horses of different ages. Five horses, one from each group, were chosen as demonstrators, and the remaining 25 horses were designated observers. Observers from each group were allowed to watch their group demonstrator opening a feeding apparatus. We found that young, low-ranking and more exploratory horses learned by observing older members of their own group, and the older the horse, the more slowly it appeared to learn. Social learning may be an adaptive specialisation to the social environment. Older animals may avoid the potential costs of acquiring complex and potentially disadvantageous feeding behaviours from younger group members. We argue that horses show social learning in the context of their social ecology and that research procedures must take such contexts into account. Misconceptions about the horse's sociality may have hampered earlier studies.

Patterns of horse-rider coordination during endurance race: a dynamical system approach.

Directory of Open Access Journals (Sweden)

Sylvain Viry

Full Text Available In riding, most biomechanical studies have focused on the description of the horse locomotion in unridden condition. In this study, we draw the prospect of how the basic principles established in inter-personal coordination by the theory of Coordination Dynamics may provide a conceptual and methodological framework for understanding the horse-rider coupling. The recent development of mobile technologies allows combined horse and rider recordings during long lasting natural events such as endurance races. Six international horse-rider dyads were thus recorded during a 120 km race by using two tri-axial accelerometers placed on the horses and riders, respectively. The analysis concentrated on their combined vertical displacements. The obtained shapes and angles of Lissajous plots together with values of relative phase between horse and rider displacements at lower reversal point allowed us to characterize four coordination patterns, reflecting the use of two riding techniques per horse's gait (trot and canter. The present study shows that the concepts, methods and tools of self-organizing dynamic system approach offer new directions for understanding horse-rider coordination. The identification of the horse-rider coupling patterns constitutes a firm basis to further study the coalition of multiple constraints that determine their emergence and their dynamics in endurance race.

The Dialogue with Hamlet: Paul-Eerik Rummo’s “Hamlet’s Songs” as an Example of the Existential Paradigm in Estonian Culture

Directory of Open Access Journals (Sweden)

2013-06-01

Full Text Available The article demonstrates different meanings of the motif of Hamlet in the Estonian culture. Hamlet as a literary figure has been very important and influential, a symbol of will and a fighter in a hopeless situation. Paul-Eerik Rummo’s poem “Hamlet’s Songs” (1964 forms the centre around which revolve not only written texts but also many such cultural texts as theatre performances and music, all connected by allusions to Hamlet. Rummo’s poem is one of the most innovative poems from the 1960s in Estonian literature. The generation of the 1960s was influenced by several important contemporary theories, including existentialism. Many young writers systematically undermined the Soviet regime in their works. The use of the motif of Hamlet reveals a similarity between the existential and romantic rebellions. Rummo’s dialogue with Hamlet in his poem expresses optimism in a hopeless situation in a way different from Shakespeare’s.

The circulation of West Nile virus (WNV) in horses was investigated in the Southwest Indian ocean. In 2010, blood samples were collected from a total of 303 horses originating from Madagascar, Mauritius, Reunion and the Seychelles and tested for WNV-specific antibodies. An overall seroprevalence of 27.39% was detected in the Indian Ocean with the highest WNV antibody prevalence of 46.22% (95% CI: [37.4-55.2%]) in Madagascar. The age and origin of the horses were found to be associated with the WNV infection risk. This paper presents the first seroprevalence study investigating WN fever in horses in the Southwest Indian Ocean area and indicates a potential risk of infection for humans and animals. In order to gain a better understanding of WN transmission cycles, WNV surveillance needs to be implemented in each of the countries. Copyright © 2017 Elsevier Ltd. All rights reserved.

Simple Summary There are approximately 200,000 unwanted horses annually in the United States. Many are shipped to slaughter, enter rescue facilities, or are held on federal lands. This study aimed to estimate a potential number of available homes for unwanted horses in order to examine broadly the viability of pursuing re-homing policies as an option for the thousands of unwanted horses in the U.S. The results of this survey suggest there could be an estimated 1.2 million homes who have both the perceived resources and desire to house an unwanted horse. This number exceeds the approximately 200,000 unwanted horses living each year in the United States. These data suggest that efforts to reduce unwanted horses could involve matching such horses with adoptive homes and enhancing opportunities to keep horses in the homes they already have. Abstract There are approximately 200,000 unwanted horses annually in the United States. This study aimed to better understand the potential homes for horses that need to be re-homed. Using an independent survey company through an Omnibus telephone (land and cell) survey, we interviewed a nationally projectable sample of 3036 adults (using both landline and cellular phone numbers) to learn of their interest and capacity to adopt a horse. Potential adopters with interest in horses with medical and/or behavioral problems and self-assessed perceived capacity to adopt, constituted 0.92% of the total sample. Extrapolating the results of this survey using U.S. Census data, suggests there could be an estimated 1.25 million households who have both the self-reported and perceived resources and desire to house an unwanted horse. This number exceeds the estimated number of unwanted horses living each year in the United States. This study points to opportunities and need to increase communication and support between individuals and organizations that have unwanted horses to facilitate re-homing with people in their community willing to adopt

This study compared serotonin concentrations in platelet poor plasma (PPP) from healthy horses and horses with surgical small intestinal (SI) colic, and evaluated their association with postoperative ileus, strangulation and non-survival. Plasma samples (with EDTA) from 33 horses with surgical SI colic were collected at several pre- and post-operative time points. Serotonin concentrations were determined using liquid-chromatography tandem mass spectrometry. Results were compared with those for 24 healthy control animals. The serotonin concentrations in PPP were significantly lower (P serotonin was not a suitable prognostic factor in horses with SI surgical colic. PMID:25694668

Hungry Horse Dam Fisheries Mitigation : Fish Passage and Habitat Improvement in the Upper Flathead River Basin, 1991-1996 Progress Report.

Knotek, W.Ladd; Deleray, Mark; Marotz, Brian L.

1997-08-01

In the past 50 years, dramatic changes have occurred in the Flathead Lake and River system. Degradation of fishery resources has been evident, in part due to deterioration of aquatic habitat and introduction of non-endemic fish and invertebrate species. Habitat loss has been attributed to many factors including the construction and operation of Hungry Horse Dam, unsound land use practices, urban development, and other anthropogenic and natural disturbances. Fish migration has also been limited by barriers such as dams and impassible culverts. Cumulatively, these factors have contributed to declines in the distribution and abundance of native fish populations. Recovery of fish populations requires that a watershed approach be developed that incorporates long-term aquatic habitat needs and promotes sound land use practices and cooperation among natural resource management agencies. In this document, the authors (1) describe completed and ongoing habitat improvement and fish passage activities under the Hungry Horse Fisheries Mitigation Program, (2) describe recently identified projects that are in the planning stage, and (3) develop a framework for identifying prioritizing, implementing, and evaluating future fish habitat improvement and passage projects.

Concerns about the contamination of meat products with horse meat and new regulations for the declaration of meat adulterants have highlighted the need for a rapid test to detect horse meat adulteration. To address this need, Microbiologique, Inc., has developed a sandwich ELISA that can quantify the presence of horse meat down to 0.1% (w/w) in cooked pork, beef, chicken, goat, and lamb meats. This horse meat authentication ELISA has an analytical sensitivity of 0.000030 and 0.000046% (w/v) for cooked and autoclaved horse meat, respectively, and an analytical range of quantitation of 0.05-0.8% (w/v) in the absence of other meats. The assay is rapid and can be completed in 1 h and 10 min. Moreover, the assay is specific for cooked horse meat and does not demonstrate any cross-reactivity with xenogeneic cooked meat sources.

During riding, horses are frequently exposed to pressure from the rider, e.g. through the bit and reins, but few studies have investigated at which point rein tension becomes uncomfortable for the horse. To investigate how much rein tension young inexperienced horses are willing to accept in order to obtain a food reward; whether the tension acceptance changes during 3 consecutive test days; and whether rein tension correlates with the expression of conflict behaviour and heart rate. Pressure-naïve horses will apply only little rein tension in the first voluntary trial, but their acceptance will gradually increase. High levels of rein tension will lead to expression of conflict behaviour and increases in heart rate. Fifteen 2-year-old, bridle-naïve mares were encouraged to stretch their head forward (across a 0.95 m high metal bar) to obtain a food reward in a voluntary test situation. On each test day, each horse was exposed to 2 control sessions (loose reins), an intermediate and a short rein session (1 min/session). Rein tension, heart rate and behaviour were recorded. The horses applied significantly more tension on the first day (mean rein tension: 10.2 N), compared to the second and third test day (Day 2: 6.0 and Day 3: 5.7 N). The horses showed significantly more conflict behaviour in the short rein treatment. There was no treatment effect on heart rate. The horses applied the highest rein tension on the first day, and apparently learned to avoid the tension, rather than habituate to it. Rein tension correlated with expression of conflict behaviour, indicating that the horses found the tension aversive. Further studies should focus on the correlation between rein tension and conflict behaviour in ridden horses. © 2010 EVJ Ltd.

New solutions for horse shelters to connect to the equestrian paths

Directory of Open Access Journals (Sweden)

Gianluca Bambi

2013-09-01

Full Text Available A rational and modern network of riding trails involves the building of specific structures for the horses according to the new needs of equestrian tourists. These shelters require appropriate technical models that today cannot be found easily in the Italian or foreign literature. Over the years this gap has led to the development of the practice “do it yourself”, following old techniques of construction, not able to meet the new demands of the market of horse tourism. This research has highlighted two different solutions that can meet the needs of tourists riding today, in accordance with the laws about the construction and the health part. These structures have been designed observing the principles of low impact, low cost, easy installation, complete reuse. Two kinds of structures have been planned. Temporary stay horse shelter: building to put in resting places of interest along the path (historic villages, monasteries, etc., where it is possible to arrange the horses for a few hours and allow to the riders to make a careful visit of places of interest. Overnight stay horse shelter: structure to put in particular points where horses and riders can spend the night. A new type of horse barn with annexed feed storage and saddle room. The structure is dynamic, due to the possibility to change quickly the position of the horses (max 8 places.

Keeping horses in groups is widely recommended but limited information is available about how this is implemented in practice. The aim of this survey was to describe how horses are kept in the Nordic countries in relation to sex, age, breed, and equestrian discipline and to assess owners' attitudes toward keeping horses in groups. Horse owners in Denmark, Finland, Norway, and Sweden were approached using a web-based questionnaire, which was translated into 4 languages and distributed online via equestrian forums, organizations, and social media. The number of respondents was 3,229, taking care of 17,248 horses. Only 8% of horses were never kept in groups, 47% were permanently grouped for 24 h/d, and 45% were stabled singly but grouped during turnout. Yearlings were most often permanently kept in groups (75%), mares and geldings more commonly during parts of the day (50 and 51%, respectively), and stallions were often kept alone (38%). Icelandic horses were more likely to be permanently kept in groups (36%) than warmbloods (16%) and ponies (15%). Twice as many competition horses (51%) were never grouped compared with horses used for breeding (20%) or leisure purposes (15%). The majority of respondents (86%) strongly agreed that group housing benefits horse welfare and that it is important for horses to have the company of conspecifics (92%). Nevertheless, not all horses were kept in groups, showing that attitudes toward group housing may not necessarily reflect current management. The risk of injury was a concern of many respondents (45%), as was introducing unfamiliar horses into already established groups (40%) and challenges in relation to feeding in groups (44%). Safety of people (23%) and difficulties handling group-kept horses (19%) were regarded as less problematic. Results suggest that the majority of horses have the possibility to freely interact with other horses, either as fulltime members of a group during 24 h/d or during turnout. Future research should

This review aims to provide practical outcomes on how to minimise the incidence of transport-related problem behaviours (TRPBs) in horses. TRPBs are unwanted behaviours occurring during different phases of transport, most commonly, a reluctance to load and scrambling during travelling. TRPBs can result in injuries to horses and horse handlers, horse trailer accidents, disruption of time schedules, inability to attend competitions, and poor performance following travel. Therefore, TRPBs are recognised as both a horse-related risk to humans and a human-related risk to horses. From the literature, it is apparent that TRPBs are common throughout the entire equine industry, and a YouTube keyword search of 'horse trailer loading' produced over 67,000 results, demonstrating considerable interest in this topic and the variety of solutions suggested. Drawing upon articles published over the last 35 years, this review summarises current knowledge on TRPBs and provides recommendations on their identification, management, and prevention. It appears that a positive human-horse relationship, in-hand pre-training, systematic training for loading and travelling, appropriate horse handling, and the vehicle driving skills of the transporters are crucial to minimise the incidence of TRPBs. In-hand pre-training based on correct application of the principles of learning for horses and horse handlers, habituation to loading and travelling, and self-loading appear to minimise the risk of TRPBs and are therefore strongly recommended to safeguard horse and horse-handler health and welfare. This review indicates that further research and education with respect to transport management are essential to substantially decrease the incidence of TRPBs in horses.

The objective of this observational study is to describe clinical, haematological and serum biochemical findings of horses affected with alfalfa dodder (Cuscuta campestris) toxicity. Twenty horses naturally exposed to alfalfa dodder toxicity were examined and information was collected on history and clinical signs. Physical examination was done on horses in the premises (n=20), and venous blood samples of 12 horses were submitted for haematology and serum biochemical examination for each horse. Abnormal clinical signs started around 36 hours after horses were fed the contaminated alfalfa. Abnormal signs were seen in 11 horses and those included diarrhoea (n=8), decreased appetite (n=7), neurological signs (n=4) and abdominal pain (n=1). Some horses had multiple clinical signs of the above. The results of complete blood cell count revealed leukocytopenia, neutropenia and thrombocytopenia. Serum biochemical analysis revealed decreased ALP, AST and CPK levels and increased direct bilirubin level. The used alfalfa was stopped immediately and a different alfalfa from a new container that did not contain any weeds was fed. Horses on the premises were observed closely, and the abnormal clinical signs resolved within three days. No treatment was implemented. Knowledge about toxicity of horses by Cuscuta species is scarce in the English veterinary literature and very limited.

Full Text Available This study aimed to analyze the genetic variability of the Italian Heavy Draught Horse (IHDH breed using a panel of 23 microsatellite markers. We also compared the population structure of the IHDH to other two unrelated breeds (Italian Haflinger, IH and Quarter Horse, QH. The IHDH showed a genetic variability comparable with other European heavy draught horse breeds and with the IH and QH breeds analyzed. Clustering analyses using a posterior Bayesian approach clearly differentiated the three breeds; it also showed a fragmentation of the IHDH in three subpopulations that need to be further investigated. These findings are an indicator of the present situation of the IHDH and will contribute to the conservation and implementation of the selection programme for this breed.

Full Text Available In 1992 the reintroduction program of the Przewalski’s horses in Mongolia was initiated, and totally 84 individuals of Przewalski’s horses were brought to the Hustai National Park between 1992 and 2000. At the same time another reintroduction program of the Przewalski’s horses was started, and 87 individuals were released in the Ta hiin T al (Bijiin Gol area in the semi-desert ecosystem of Southwestern Mongolia. Recently , in the Khomyn Tal ar ea of We s tern Mongolia transferred 24 individuals of Przewalski’s horses from zoos (the reintroduction program was started in 2004. All captive Przewalski’s horses were released into the wild (in 1994 in Hustai, and 1996 in Tah iin T al, and the populations of horses are gradually increasing in both sites. In this work, the results of analyses on the population dynamics of Przewalski’ s horses, reintroduced in these two sites are discussed.

Mechanics of evolutionary digit reduction in fossil horses (Equidae).

2017-08-30

Digit reduction is a major trend that characterizes horse evolution, but its causes and consequences have rarely been quantitatively tested. Using beam analysis on fossilized centre metapodials, we tested how locomotor bone stresses changed with digit reduction and increasing body size across the horse lineage. Internal bone geometry was captured from 13 fossil horse genera that covered the breadth of the equid phylogeny and the spectrum of digit reduction and body sizes, from Hyracotherium to Equus To account for the load-bearing role of side digits, a novel, continuous measure of digit reduction was also established-toe reduction index (TRI). Our results show that without accounting for side digits, three-toed horses as late as Parahippus would have experienced physiologically untenable bone stresses. Conversely, when side digits are modelled as load-bearing, species at the base of the horse radiation through Equus probably maintained a similar safety factor to fracture stress. We conclude that the centre metapodial compensated for evolutionary digit reduction and body mass increases by becoming more resistant to bending through substantial positive allometry in internal geometry. These results lend support to two historical hypotheses: that increasing body mass selected for a single, robust metapodial rather than several smaller ones; and that, as horse limbs became elongated, the cost of inertia from the side toes outweighed their utility for stabilization or load-bearing. © 2017 The Author(s).

The absolute threshold of colour vision in the horse.

Full Text Available Arrhythmic mammals are active both during day and night if they are allowed. The arrhythmic horses are in possession of one of the largest terrestrial animal eyes and the purpose of this study is to reveal whether their eye is sensitive enough to see colours at night. During the day horses are known to have dichromatic colour vision. To disclose whether they can discriminate colours in dim light a behavioural dual choice experiment was performed. We started the training and testing at daylight intensities and the horses continued to choose correctly at a high frequency down to light intensities corresponding to moonlight. One Shetland pony mare, was able to discriminate colours at 0.08 cd/m(2, while a half blood gelding, still discriminated colours at 0.02 cd/m(2. For comparison, the colour vision limit for several human subjects tested in the very same experiment was also 0.02 cd/m(2. Hence, the threshold of colour vision for the horse that performed best was similar to that of the humans. The behavioural results are in line with calculations of the sensitivity of cone vision where the horse eye and human eye again are similar. The advantage of the large eye of the horse lies not in colour vision at night, but probably instead in achromatic tasks where presumably signal summation enhances sensitivity.

Adapting craniosacral therapy to treat horses

Directory of Open Access Journals (Sweden)

Weronika Kanik

2017-01-01

Full Text Available Craniosacral therapy is an acknowledged therapeutic method used for treating humans. It derives from osteopathy, being a manual technique which uses a very gentle touch. It consists in balancing the fluctuation of cerebrospinal fluid by applying appropriate holds that make it possible for the patientŐs organism to release tensions which have formed in tissues. The aim of the present work was to depict the possibility to adapt the method of craniosacral therapy used in humans to the therapy of horses. Thirteen therapeutic holds proposed for the treatment of horses were described and interpreted graphically on the basis of therapy of 62 horses with different disorders. A total of 241 craniosacral therapy treatments were performed. The adaptation of presented craniosacral therapy holds to equine therapy was developed by the first author on the basis of relevant holds used in the biodynamic craniosacral therapy in humans and in own therapeutic practice. The effects of own practice and data available in literature suggest that craniosacral therapy seems to be an effective method of improving the state of health of horses suffering from different complaints that may cause major difficulties in sport, breeding or private use of the animals. The use of thermography made it possible to record the effects of therapy and some processes accompanying it, which had been impossible before.

Feed, energy and protein intakes of horses - A review of Finnish feeding trials

Directory of Open Access Journals (Sweden)

Markku Saastamoinen

1993-01-01

Full Text Available The aim of this study was to evaluate the feed, energy and protein intakes of horses engaged in different performances by reviewing results and data concerning feed consumption in 17 feeding trials with a total 356 horses, conducted between 1972 and 1992. The dry matter intake was found to average 1.6-1.8% of body weight for working horses and pregnant mares, and 2-3.5% for lactating mares. According to the results most of the exercising horses could be fed with energy and protein amounts currently recommended for moderate work. In Standardbred trotters, the average energy intake corresponded to the current requirements for light work. The individual variation in energy consumption among horses engaged in work of the same intensity was considerable, and seemed to be larger for Finnhorses than for warmblooded horses. The establishment of new nutrient requirements and feeding recommendations separately for trotters and riding horses of these two breeds, i.e. Finnhorses and warmblooded horses, seems justified.

Genome-wide detection of copy number variations among diverse horse breeds by array CGH.

Directory of Open Access Journals (Sweden)

Wei Wang

Full Text Available Recent studies have found that copy number variations (CNVs are widespread in human and animal genomes. CNVs are a significant source of genetic variation, and have been shown to be associated with phenotypic diversity. However, the effect of CNVs on genetic variation in horses is not well understood. In the present study, CNVs in 6 different breeds of mare horses, Mongolia horse, Abaga horse, Hequ horse and Kazakh horse (all plateau breeds and Debao pony and Thoroughbred, were determined using aCGH. In total, seven hundred CNVs were identified ranging in size from 6.1 Kb to 0.57 Mb across all autosomes, with an average size of 43.08 Kb and a median size of 15.11 Kb. By merging overlapping CNVs, we found a total of three hundred and fifty-three CNV regions (CNVRs. The length of the CNVRs ranged from 6.1 Kb to 1.45 Mb with average and median sizes of 38.49 Kb and 13.1 Kb. Collectively, 13.59 Mb of copy number variation was identified among the horses investigated and accounted for approximately 0.61% of the horse genome sequence. Five hundred and eighteen annotated genes were affected by CNVs, which corresponded to about 2.26% of all horse genes. Through the gene ontology (GO, genetic pathway analysis and comparison of CNV genes among different breeds, we found evidence that CNVs involving 7 genes may be related to the adaptation to severe environment of these plateau horses. This study is the first report of copy number variations in Chinese horses, which indicates that CNVs are ubiquitous in the horse genome and influence many biological processes of the horse. These results will be helpful not only in mapping the horse whole-genome CNVs, but also to further research for the adaption to the high altitude severe environment for plateau horses.

Exertional rhabdomyolysis (ER) is a reported syndrome in competing endurance horses; however, the prevalence and cause of ER in this population have not been defined. To determine the prevalence of ER in a sample of endurance racing horses and investigate factors, including relevant genetic defects, contributing to the occurrence of rhabdomyolysis in this group. Prospective clinical study. Riders of 101 horses participating in one of four 50-mile (80.5 km) distance races completed a comprehensive questionnaire regarding the medical history, management and performance of their horse. Serum creatine kinase activity (CK) was measured before and 4 h after completion of exercise. Hair samples were analysed by PCR for the R309H mutation in the glycogen synthase gene (GYS1) responsible for type 1 polysaccharide storage myopathy (PSSM) and the C7360G mutation in the ryanodine receptor 1 (RYR1) gene causing malignant hyperthermia (MH). Samples were obtained from 68 Arabians, 20 half-Arabians and 13 horses of other breeds. Serum CK was above the resting reference interval (145-633 u/l) in 38 horses after racing (median 883 u/l, range 658-3739) but was compatible with values previously reported in apparently healthy endurance horses. Pathological ER was suspected to occur in 4 horses with serum CK activities exceeding 10,000 u/l 4 h after racing (median 84,825 u/l; range 10,846-381,790) including 3 Arabians and one half-Arabian horse. GYS1 and RYR1 mutations were not present in hair samples from any horses. Exertional rhabdomyolysis occurred at a prevalence of 4.0% in a sample of horses participating in 50 mile distance events and all affected horses were Arabian or half-Arabian. The cause of ER in the endurance horse population remains unknown; however, ER in competing Arabian endurance horses is unlikely to be due to type 1 PSSM or MH. © 2014 EVJ Ltd.

Full Text Available Recession has sharply erected the question of tax burden and the optimal proportion of different kinds of taxes among the incomes of the budget. Indirect taxes and consumption taxes, which proportion is different according to different methodologies, dominate in Estonian state budget. The buoyancy of a tax system based on taxes of that kind is especially weak during the recession. Difficulties concerning the incomes of budget have arisen the necessity for lifting taxes, which is possible as the tax burden is low now. But a sharp question of the optimal level of taxes is going to be raised. A formula for indirect tax optimum according to Ramsey taxes and Slutski decomposition has been proposed in the article.

In this document we present fisheries losses, mitigation alternatives, and recommendations to protect, mitigate, and enhance resident fish and aquatic habitat affected by the construction and operation of Hungry Horse Dam. This plan addresses six separate program measures in the 1987 Columbia Basin Fish and Wildlife Program. We designed the plan to be closely coordinated in terms of dam operations, funding, and activities with the Kerr Mitigation Plan presently before the Federal Energy Regulatory Commission. This document represents a mitigation plan for consideration by the Northwest Power Planning Council process; it is not an implementation plan. Flathead Lake is one of the cleanest lakes of its size in the world. The exceptional water quality and unique native fisheries make the Flathead Lake/River system extremely valuable to the economy and quality of life in the basin. The recreational fishery in Flathead Lake has an estimated value of nearly eight million dollars annually. This mitigation process represents our best opportunity to reduce the impacts of hydropower in this valuable aquatic system and increase angling opportunity. We based loss estimates and mitigation alternatives on an extensive data base, agency reports, nationally and internationally peer-reviewed scientific articles, and an innovative biological model for Hungry Horse Reservoir and the Flathead River. We conducted an extensive, 14-month scoping and consultation process with agency representatives, representatives of citizen groups, and the general public. This consultation process helped identify issues, areas of agreement, areas of conflict, and advantages and disadvantages of mitigation alternatives. The results of the scoping and consultation process helped shape our mitigation plan. Our recommended plan is based firmly on principles of adaptive management and recognition of biological uncertainty. After we receive direction from the NPPC, we will add more detailed hypotheses and

2012-07-01

Full Text Available Abstract Background Clipping the winter coat in horses is done to improve heat dissipation during exercise and make grooming easier. It is often combined with blanketing to keep the horse warm. The aims of the present study were to investigate how clipping and the use of blankets affect thermoregulation during exercise and recovery in horses. Methods One Gotland pony, one New Forest pony, and one warm-blooded horse exercised one after the other on a 6450 m long track. The horses walked, trotted and cantered according to a predetermined scheme, which took about 50 minutes including three stops. The scheme was repeated on five consecutive days when horses were: 1 unclipped 2 unclipped + blanket during recovery, 3 left or right side clipped, 4 clipped, and 5 clipped + riding blanket + blanket during recovery. Heart rate (HR was measured with telemetry, respiratory rate (RR by counting flank contractions, skin temperatures by thermistor probes, and rectal temperature with a digital thermometer. Skin wetness (SW was estimated by ocular inspection (dripping = 5, dry = 0. Results Mean outdoor temperature varied from -1.1 to - 8.7°C. HR increased progressively during exercise with no difference between treatments. Maximum RR was 77 ± 30 breaths/min (unclipped and 49 ± 27 breaths/min (clipped. The lowest skin temperature was 17.5 ± 2.7°C in a hind leg during exercise, which increased to 34.5 ± 0.1°C during recovery. Rectal temperature was elevated during recovery in unclipped, but not in clipped horses and skin temperature at base of tail was elevated during recovery except in unclipped horses without blanket. Moisture after exercise scored 3.2 ± 0.8 in unclipped and zero in clipped horses. Discussion and conclusion Leg skin temperature initially dropped at onset of exercise in clipped horses, and then increased after about 30 minutes due to internal heat from the working muscles. These changes were not significant when

A discovery in 2002 of a Trichinella spiralis-infected horse in Serbia offered an opportunity to conduct needed epidemiological studies on how horses, considered herbivores, acquire a meat-borne parasite. This enigma has persisted since the first human outbreaks from infected horse meat occurred in then 1970s. The trace back of the infected horse to a farm owner was carried out. Interviews and investigations on the farm led to the conclusion that the owner had fed the horse food waste in order to condition the horse prior to sale. Further investigations were then carried out to determine the frequency of such practices among horse owners. Based on interviews of horse producers at local horse markets, it was revealed that the feeding of animal products to horses was a common practice. Further, it was alleged that many horses, particularly those in poor nutritional condition would readily consume meat. A subsequent series of trials involving the experimental feeding of 219 horses demonstrated that 32% would consume meat patties. To confirm that horses would eat infected meat under normal farm conditions, three horses were offered infected ground pork balls containing 1100 larvae. All three became infected, and at necropsy at 32 weeks later, were still positive by indirect IFA testing, but not by ELISA using an excretory-secretory (ES) antigen. This result indicates that further study is needed on the nature of the antigen(s) used for potential serological monitoring and surveillance of horse trichinellosis, especially the importance of antigenic diversity. The experimentally-infected horses also had very low infection levels (larvae per gram of muscle) at 32 weeks of infection, and although the public health consequences are unknown, the question of whether current recommended inspection procedures based on pepsin digestion of selected muscle samples require sufficient quantities of muscle should be addressed. It is concluded that horses are more willing to consume

Relation between type and local of orthopedic injuries with physical activity in horses

Directory of Open Access Journals (Sweden)

Nicole Ruas de Sousa

Full Text Available ABSTRACT: Equine sport modalities influence the prevalence and predisposition of musculoskeletal injuries in horses. This study aimed to evaluate the prevalence of location and type of orthopedic injuries of horses undergoing various physical activities. Data from 116 horses of different breeds and ages was analyzed. Physical activities included dressage, racing, polo pony, jumping, work and western performance. All horses had history of orthopedic lameness diagnosed by radiographs and/or ultrasound scans. The effect of sport on the affected anatomical site and type of lesion was performed using Fisher's exact test. Desmitis was more prevalent in animals that performed western sports than in the working ones. The number of fractures was greater in racing and polo pony animals than in working horses. Stifle lesions were more prevalent in dressage horses than working horses and had lower occurrence of shoulder injuries than jumping horses. Hind limb tendon injuries were lower in jumping than in dressage and western horses. We conclude that there is a relationship between location and type of injury and physical activities. In racing horses there is a predominance of young animals and higher prevalence of orthopedic injuries from traumatic events such as tendonitis, desmitis and fractures. In physical activities that require longer training and that animals were used for longer periods, eg. jumping, polo pony, dressage and work, age-related degenerative, such as joint disease, were predominant. In western sport animals the most common lesion was desmitis. Regarding limbs, forelimb injures were more often observed in racing horses, polo pony, jumping and working animals; whereas, dressage and Western sports horses presented more injuries in hind limbs.

Towards an ethological animal model of depression? A study on horses.

Directory of Open Access Journals (Sweden)

Carole Fureix

Full Text Available Recent reviews question current animal models of depression and emphasise the need for ethological models of mood disorders based on animals living under natural conditions. Domestic horses encounter chronic stress, including potential stress at work, which can induce behavioural disorders (e.g. "apathy". Our pioneering study evaluated the potential of domestic horses in their usual environment to become an ethological model of depression by testing this models' face validity (i.e. behavioural similarity with descriptions of human depressive states.We observed the spontaneous behaviour of 59 working horses in their home environment, focusing on immobility bouts of apparent unresponsiveness when horses displayed an atypical posture (termed withdrawn hereafter, evaluated their responsiveness to their environment and their anxiety levels, and analysed cortisol levels. Twenty-four percent of the horses presented the withdrawn posture, also characterized by gaze, head and ears fixity, a profile that suggests a spontaneous expression of "behavioural despair". When compared with control "non-withdrawn" horses from the same stable, withdrawn horses appeared more indifferent to environmental stimuli in their home environment but reacted more emotionally in more challenging situations. They exhibited lower plasma cortisol levels. Withdrawn horses all belonged to the same breed and females were over-represented.Horse might be a useful potential candidate for an animal model of depression. Face validity of this model appeared good, and potential genetic input and high prevalence of these disorders in females add to the convergence. At a time when current animal models of depression are questioned and the need for novel models is expressed, this study suggests that novel models and biomarkers could emerge from ethological approaches in home environments.

2014-01-01

Full Text Available Introduction: Fractures have been described mainly following falling accidents in horse-related injuries. Horse bites are uncommon accidents. We present a case of open fracture of the forearm due to horse bite. Case Report: A 35-year-old male farm-worker presented to the emergency room with alleged history of horse bite to the right forearm about 2 hours prior to presentation while feeding the horse. There was deformity of the forearm with multiple puncture wounds, deep abrasions and small lacerations on the distal-third of the forearm. Copious irrigation with normal saline was done and he was administered anti-tetanus and post-exposure rabies prophylaxis. Prophylactic antibiotic therapy was commenced. Radiographs revealed fracture of radius and ulna in the mid-shaft region. He underwent emergency wound debridement, and the ulna was stabilised with an intra-medullary square nail. Seventy-two hours later, he underwent re-debridement and conversion osteosynthesis. He had an uneventful recovery and at three-month follow-up, the fractures had healed radiographically in anatomic alignment. At two-year follow-up, he is doing well, is pain free and has a normal range of motion compared to the contralateral side. Conclusion: Horse bites behave as compound fractures however rabies prophylaxis will be needed and careful observation is needed. Early radical debridement, preliminary skeletal stabilisation, re-debridement and conversion osteosynthesis to plate, and antibiotic prophylaxis were the key to the successful management of our patient.

2016-01-01

On the initiative of the Office National des Forêts, France’s forestry commission, horses are helping to remove trees cut down in CERN’s forests.   The CERN site covers 625 hectares, of which around 200 are fenced sites used for CERN’s research activities. The rest of the land consists of fields rented out to farmers and about 90 hectares of forests, mainly in France and managed by the French forestry commission, the Office National des Forêts (ONF), under an agreement with CERN signed in 2010. The upkeep of CERN’s forests requires regular maintenance work, which includes thinning out seedlings, selecting the strongest saplings and harvesting mature trees. This June, the ONF has decided to involve horses in the removal of felled trees from CERN’s woods in Prévessin.  As Florent Daloz, the logger entrusted with this activity by the ONF, explains, the use of horses to haul timber completely died out i...

Five horses, weighing 337 to 400 kg, were used in this research, one of them being used as control. Cervical myelography with iohexol (Omnipaque) was performed on four horses tranquilized with flunitrazepan before induction of anesthesia with sodium thiopental. Anesthesia was maintained with fluothane and oxygen. Cerebrospinal fluid (CSF) was analysed before and after an injection of ioxheol into the subarachnoid space. The animals received 25 to 50 ml of iohexol, after removal of 20 ml cerebrospinal fluid. Radiographies were taken with the horses at lateral recumbency, and the cranial, central and caudal regions of the cervical spine being focalized. No significant changes occurred in the cerebrospinal fluid after injecting the contrast medium. Pathologic changes were not found by gross or microscopic examination of the brain and the cervical spinal cord. Radiographies of good to excellent image quality were obtained. At autopsy, radiographic diagnosis of cervical vertebral instability was confirmed in the animal that had pelvic limb ataxia.

Five horses, weighing 337 to 400 kg, were used in this research, one of them being used as control. Cervical myelography with iohexol (Omnipaque) was performed on four horses tranquilized with flunitrazepan before induction of anesthesia with sodium thiopental. Anesthesia was maintained with fluothane and oxygen. Cerebrospinal fluid (CSF) was analysed before and after an injection of ioxheol into the subarachnoid space. The animals received 25 to 50 ml of iohexol, after removal of 20 ml cerebrospinal fluid. Radiographies were taken with the horses at lateral recumbency, and the cranial, central and caudal regions of the cervical spine being focalized.

An inquiry was carried out to assess the concentrations of plasma metabolites related to bone remodelling in 21 saddle horses of Warmblood breed aged 4-26 years, five draught horses of Ardennes breed aged 4-10 years, and 10 Ardennes foals aged 9-11 months. They were fed according to normal feeding practice in Belgium. The changes in some bone remodelling plasma metabolite concentrations were studied when an unbalanced diet was offered and later corrected for four Warmblood horses. Bone formation was evaluated by bone alkaline phosphatase (BALP), total alkaline phosphatase (TALP) and osteocalcin (bone gla-protein, OC). Bone resorption was assessed by hydroxyproline (HYP). Total calcium, ionized calcium, phosphorus (P) and 25-hydroxyvitamin D3 [25-(OH)D] concentrations were more or less constant. The comparison of four bone remodelling factors between the Ardennes and Warmblood horses showed higher concentrations in the Ardennes breed. Bone marker concentrations decreased according to age. The correction of the unbalanced Ca : P diet induced inconsistent effects at plasma level. The interpretation of the different bone parameters appeared to be difficult if not associated with other parameters such as a complete anamnesis and clinical examination of the animal in addition to dietary evaluation.

Social animals should have plenty of opportunities to learn from conspecifics, but most studies have failed to document social learning in horses. This study investigates whether young Icelandic horses can learn a spatial detour task through observation of a trained demonstrator horse of either...... the same age (Experiments 1 and 2, n = 22) or older (Experiment 3, n = 24). Observer horses were allowed to observe the demonstrator being led three times through the detour route immediately before being given the opportunity to solve the task themselves. Controls were allowed only to observe...

The consumption of horse-meat is currently not popular in most countries, but because of its availability and recognized nutritional value consumption is slowly increasing in several western European countries based on claims that it could be an alternative red meat. In this review, horse-meat production, trade and supply values have been summarized. In addition, the advantage of horse production is noted because of its lower methane emissions and increased uptake, particularly of n-3 polyunsaturated fatty acids (PUFAs), which is based on its digestive physiology. Of particular interest in this review is the unique fatty acid composition of horse-meat with its high level of the nutritionally desirable PUFAs in both the adipose and muscle fat. Because of its large frame size and digestive physiology, the horse can be considered an alternative to bovine meat, with large advantages regarding the maintenance of less favored mountain grazing areas and its facility to transfer PUFA from feed to meat.

Insect-bite hypersensitivity is the most common allergic dermatitis in horses. Excoriated skin lesions are typical symptoms of this seasonal and refractory chronic disease. On a cellular level, the skin lesions are characterized by massive eosinophil infiltration caused by an underlying allergic response. To target these cells and treat disease, we developed a therapeutic vaccine against equine IL-5 (eIL-5), the master regulator of eosinophils. The vaccine consisted of eIL-5 covalently linked to a virus-like particle derived from cucumber mosaic virus containing the tetanus toxoid universal T-cell epitope tt830-843 (CMV TT ). Thirty-four Icelandic horses were recruited and immunized with 400 μg of eIL-5-CMV TT formulated in PBS without adjuvant (19 horses) or PBS alone (15 horses). The vaccine was well tolerated and did not reveal any safety concerns but was able to induce anti-eIL-5 autoantibody titers in 17 of 19 horses. This resulted in a statistically significant reduction in clinical lesion scores when compared with previous season levels, as well as levels in placebo-treated horses. Protection required a minimal threshold of anti-eIL-5 antibodies. Clinical improvement by disease scoring showed that 47% and 21% of vaccinated horses reached 50% and 75% improvement, respectively. In the placebo group no horse reached 75% improvement, and only 13% reached 50% improvement. Our therapeutic vaccine inducing autoantibodies against self IL-5 brings biologics to horses, is the first successful immunotherapeutic approach targeting a chronic disease in horses, and might facilitate development of a similar vaccine against IL-5 in human subjects.

Increased doses of detomidine are required to produce sedation in horses after maximal exercise compared to calm or resting horses. To determine if the pharmacokinetics of detomidine in Thoroughbred horses are different when the drug is given during recuperation from a brief period of maximal exercise compared to administration at rest. Six Thoroughbred horses were preconditioned by exercising them on a treadmill. Each horse ran a simulated race at a treadmill speed that caused it to exercise at 120% of its maximal oxygen consumption. One minute after the end of exercise, horses were treated with detomidine. Each horse was treated with the same dose of detomidine on a second occasion a minimum of 14 days later while standing in a stocks. Samples of heparinised blood were obtained at various time points on both occasions. Plasma detomidine concentrations were determined by liquid chromatography-mass spectrometry. The plasma concentration vs. time data were analysed by nonlinear regression analysis. Median back-extrapolated time zero plasma concentration was significantly lower and median plasma half-life and median mean residence time were significantly longer when detomidine was administered after exercise compared to administration at rest. Median volume of distribution was significantly higher after exercise but median plasma clearance was not different between the 2 administrations. Detomidine i.v. is more widely distributed when administered to horses immediately after exercise compared to administration at rest resulting in lower peak plasma concentrations and a slower rate of elimination. The dose requirement to produce an equivalent effect may be higher in horses after exercise than in resting horses and less frequent subsequent doses may be required to produce a sustained effect.

To investigate associations between the bacteriology and aspects of history, clinical presentation, outcome and pathology of lower respiratory tract disease of 34 horses. Detailed aerobic and anaerobic bacteriological investigations were performed on clinical specimens from horses with pneumonia, lung abscessation and necrotic pneumonia with or without pleurisy in an attempt to identify those bacteria that might contribute to the initiation and progression of infection. Bacteria were cultured from 33 of the 34 horses. In ten cases, only aerobic/facultatively anaerobic isolates were cultured while aerobic/facultatively anaerobic bacteria and obligately anaerobic bacteria were isolated in the other 23 cases. Moderate to large numbers of anaerobic bacteria were isolated only when the estimated duration of illness was at least five days. Bacteria were not cultured from 12 of the pleural fluid samples but were always cultured from pulmonary samples (either transtracheal aspirates from live horses or pulmonary lesions at necropsy). Streptococcus equi subsp zooepidemicus was isolated in the three cases where only one bacterial species was cultured. In the other 30 cases, multiple species were isolated. These included most often and in greatest numbers, Streptococcus equi subsp zooepidemicus, Pasteurellaceae, Escherichia coli, anaerobic cocci, Eubacterium fossor, Bacteroides tectum, Prevotella heparinolytica, Fusobacterium spp, and pigmented members of the genera Prevotella and Porphyromonas. Aerobic/facultatively anaerobic organisms were isolated from 97% of horses, while obligately anaerobic organisms were cultured from 68% of horses. There was no association between the isolation of any specific bacterium and the outcome of disease. However, obligately anaerobic bacteria (such as anaerobic cocci, Bacteroides tectum, P heparinolytica and Fusobacterium spp) and the facultatively anaerobic species Escherichia coli, were recovered more commonly from horses that died or were

The aim of this study was to determine the normal location, wall thickness and motility of the right dorsal colon in adult ponies and miniature horses. The abdominal ultrasonography examination was performed in a study group consisting of 23 ponies and miniature horses and in a control group comprising ten Thoroughbred horses. The procedure was performed in unsedated standing animals. The location and the thickness of the right dorsal colonic wall was examined on the right side of the abdomen between the 10th and the 14th intercostal space. The contractility was recorded in the 12th intercostal space. A comparative analysis between the study group and control group was carried out using the Student’s t-test. Pearson’s linear correlation coefficient was used to calculate the correlation between the thickness of the colonic wall as well as the number of peristaltic movements and age, wither height and body mass of the animals. The right dorsal colon was identified in all the horses in the 12th intercostal space. In all the intercostal spaces the mean ± standard deviation (SD) wall thickness of the right dorsal colon was 0.27 ± 0.03 cm in the horses from the study group and 0.37 ± 0.03 cm in the control horses. The mean number of peristaltic contractions was 4.05 ± 1.07 per minute in the animals from the study group and 1.7 ± 0.46 contractions per minute in the control group. The values of the ultrasonographic wall thickness and peristaltic motility in small breed horses in the present study were different from the values obtained for large breed horses. The study also found that the right dorsal colon in small breed horses is physiologically located in the 12th intercostal space. This suggests that different reference values should be used in small horse breeds when performing an ultrasound examination. PMID:29065146

Equine protozoal myeloencephalitis (EPM) due to Sarcocystis neurona infection is 1 of the most common neurologic diseases in horses in the United States. The mechanisms by which most horses resist disease, as well as the possible mechanisms by which the immune system may be suppressed in horses that develop EPM, are not known. Therefore, the objectives of this study were to determine whether horses experimentally infected with S. neurona developed suppressed immune responses. Thirteen horses that were negative for S. neurona antibodies in serum and cerebrospinal fluid (CSF) were randomly assigned to control (n = 5) or infected (n = 8) treatment groups. Neurologic exams and cerebrospinal fluid analyses were performed prior to, and following, S. neurona infection. Prior to, and at multiple time points following infection, immune parameters were determined. All 8 S. neurona-infected horses developed clinical signs consistent with EPM, and had S. neurona antibodies in the serum and CSF. Both infected and control horses had increased percentages (P < 0.05) of B cells at 28 days postinfection. Infected horses had significantly decreased (P < 0.05) proliferation responses as measured by thymidine incorporation to nonspecific mitogens phorbol myristate acetate (PMA) and ionomycin (I) as soon as 2 days postinfection.

Chronic progressive lymphoedema (CPL) is a recently recognised disease of the lymphatic system characterised by lesions in the skin of the lower legs in several draught horse breeds, including the Belgian Draught hourse. Clinical signs slowly progress and result in severe disfigurement of the limbs. Ideally, supportive treatment should be started early in the disease process. However early diagnosis and monitoring progression of CPL is still a challenge. Elastin changes, characterised by morphological alterations as well as increased desmosine levels, in the skin of the distal limbs of horses affected with CPL are probably associated with a marked release of elastin degradation products, which elicit production of circulating anti-elastin antibodies (AEAbs) in the serum. An enzyme-linked immunosorbent assay (ELISA) for detection of serum AEAbs may document elastin breakdown. An ELISA technique was used to evaluate levels of AEAbs in sera of 97 affected Belgian Draught horses that were clinically healthy except for possible skin lesions, associated with CPL in their distal limbs. The horses were divided into 5 groups according to the severity of these skin lesions: normal horses (Group 1, n = 36), horses with mild lesions (Group 2, n = 43), horses with moderate lesions (Group 3, n = 8), horses with severe lesions (Group 4, n = 10) and, as a control, healthy Warmblood horses, unaffected by the disease (Group 5, n = 83). Horses with clinical signs of CPL had significantly higher AEAb levels compared to clinically normal Belgian Draught horses and to healthy Warmblood horses. These levels correlated with severity of lesions. CPL in draught horses is associated with an increase of serum AEAbs. Evaluation of serum levels of AEAbs by ELISA might be a useful diagnostic aid for CPL. Pathological degradation of elastic fibres, resulting in deficient support of the distal lymphatics, is proposed as a contributing factor for CPL in Belgian Draught horses.

Candidate genes for performance in horses, including monocarboxylate transporters

Directory of Open Access Journals (Sweden)

Inaê Cristina Regatieri

Full Text Available ABSTRACT: Some horse breeds are highly selected for athletic activities. The athletic potential of each animal can be measured by its performance in sports. High athletic performance depends on the animal capacity to produce energy through aerobic and anaerobic metabolic pathways, among other factors. Transmembrane proteins called monocarboxylate transporters, mainly the isoform 1 (MCT1 and its ancillary protein CD147, can help the organism to adapt to physiological stress caused by physical exercise, transporting lactate and H+ ions. Horse breeds are selected for different purposes so we might expect differences in the amount of those proteins and in the genotypic frequencies for genes that play a significant role in the performance of the animals. The study of MCT1 and CD147 gene polymorphisms, which can affect the formation of the proteins and transport of lactate and H+, can provide enough information to be used for selection of athletic horses increasingly resistant to intense exercise. Two other candidate genes, the PDK4 and DMRT3, have been associated with athletic potential and indicated as possible markers for performance in horses. The oxidation of fatty acids is highly effective in generating ATP and is controlled by the expression of PDK4 (pyruvate dehydrogenase kinase, isozyme 4 in skeletal muscle during and after exercise. The doublesex and mab-3 related transcription factor 3 (DMRT3 gene encodes an important transcription factor in the setting of spinal cord circuits controlling movement in vertebrates and may be associated with gait performance in horses. This review describes how the monocarboxylate transporters work during physical exercise in athletic horses and the influence of polymorphisms in candidate genes for athletic performance in horses.

Full Text Available In many countries the primary (mother tongue language is not English but there is a great demand for English language teachers all over the world. The demand in this field is try to be filled largely by non-native English speaking teachers who have learned English in the country or abroad, or from another non native English peaking teachers. In some countries, particularly those where English speaking is a a sign of status, the students prefer to learn English from a native English speaker. The perception is that a non-native English speaking teacher is a less authentic teacher than a native English speaker and their instruction is not satifactory in some ways. This paper will try to examine the literature to explore whether there is a difference in instructional effectiveness between NNESTs and native English teachers.

Extensive genetic variation is observed within the genus Cryptosporidium and the distribution of Cryptosporidium species/genotypes in humans and animals appears to vary by geography and host species. To better understand the genetic diversity of Cryptosporidium spp. in horses and donkeys, we characterized five horse-derived and 82 donkey-derived Cryptosporidium isolates from five provinces or autonomous regions (Sichuan, Gansu, Henan, Inner Mongolia and Shandong) in China at the species/genotype and subtype levels. Three Cryptosporidium species/genotypes were identified based on the analysis of the SSU rRNA gene, including Cryptosporidium parvum (n=22), the Cryptosporidium horse genotype (n=4), and Cryptosporidium hominis (n=61). The identification of C. hominis was confirmed by sequence analysis of the HSP70 and actin genes. Subtyping using sequence analysis of the 60kDa glycoprotein gene identified 21 C. parvum isolates as subtype IIdA19G1, the four horse genotype isolates as subtypes VIaA15G4 (n=2) and VIaA11G3 (n=2), and the 61 C. hominis isolates as IkA16G1 (n=59) and IkA16 (n=2). The common finding of C. hominis reaffirms the heterogeneity of Cryptosporidium spp. in horses and donkeys and is possibly a reflection of endemic transmission of C. hominis in these animals. Data of the study suggest that horses and donkeys as companion animals may potentially transmit Cryptosporidium infections to humans. Copyright © 2016 Elsevier B.V. All rights reserved.

Using laser microdissection we prepared a set of horse chromosome arm-specific probes. Most of the probes were generated from horse chromosomes, some of them were derived from Equus zebra hartmannae. The set of probes were hybridized onto E. grevyi chromosomes in order to establish a genome-wide chromosomal correspondence between this zebra and horse. The use of arm-specific probes provided us with more information on the mutual arrangement of the genomes than we could obtain by means of whole-chromosome paints generated by flow sorting, even if we used reciprocal painting with probe sets from both species. By comparison of our results and results of comparative mapping in E. burchelli, we also established the chromosomal correspondence between E. grevyi and E. burchelli, providing evidence for a very close karyotypic relationship between these two zebra species. Establishment of the comparative map for E. grevyi contributes to the knowledge of the karyotypic phylogeny in the Equidae family.
