De inhysningssystem som används idag möter inte alltid hästens naturliga behov. En traditionell uppstallning hindrar hästen att utföra sitt naturliga rörelsebehov. Genom att ge hästarna möjlighet till mer rörelse kan man få flera hälsomässiga fördelar. Exempel på fördelar är ett starkare skelett, starkare senor, bättre kondition och minskad stress vid uppstallning och träning. Syftet med denna studie är att ta reda på om hästar rör sig mer beroende på olika inhysningssystem som ger olika förutsättningar för rörelse.

This thesis constitutes a long term (100 year) ecological landscape management plan for the estate Götebo 1:5. The estate is situated close to Gothenburg and is owned by Skogssällskapet. The planning has been made by dividing the estate into different areas (zones). In each zone one of the goals nature conservation, recreation or economical yield has been prioritized. Nature conservation is one of the main goals for the forest management plan.

The goal of this work has been to search historical materials, to identify the park's historical development, to prepare proposals on measures and that work should be the basis for further research. The aim has been to train us in searching for and use of materials and to gain an understanding of the process of work with older plants. In the process we have sought and found materials in archives, through literary and oral sources, and email contacts. Because of its excellent location perched on an islet in the low landscape Näsbyholm was long a fortress. The old castle on Näsbyholm was from the late 1400s but the site was fortified much earlier. The islet was at this time completely surrounded by water and there was a drawbridge over the narrow waterline. The owners are liable since the late 1200s.

The purpose of the study was to investigate whether or not Icelandic horses are less severely affected in clinical symptoms of cough or decreased performance than other breeds of horses. A breed variation in chronic respiratory disease severity was suspected based on clinical experience at the Institution for surgery & medicine, large animal, SLU Uppsala. A retrospective journal study of 17 Icelandic horses and 17 Swedish Standardbred horses with chronic problems with cough and/or decreased performance compared several measurements of disease severity. The clinical signs, physical examination and laboratory testing results compared were respiratory rate, abdominal breathing, lung auscultation, endoscopy results, broncho-alveolar lavage (BAL) results and the blood gases pO2 and pCO2. All parameters were available for all 34 individuals except for the blood gases, which were analysed, in only four Icelandic horses and four Swedish Standardbred horses. The only parameters that appeared different between the two groups were respiratory rate and pO2. The four Icelandic horses, which had blood gases analysed, had more severe hypoxemia.

Today, equine breeding is based on performance and conformation, resulting in a vast variation in fertility among different horses, with noticeable economic losses as a consequence. The horse breeding industry is therefore in need of methods that diagnose the spermatozoa concerning their quality and provide the best sperm for AI. The commonly used selection methods for sperm today are: centrifugation, where extender is added, the sample is centrifuged and then resuspended; swim-up self-migration; adherence separation; and density gradient centrifugation. However, none of these methods are in used routinely in practice before inseminating mares with fresh or cooled semen. The aim of this study was to evaluate a new selection method, Single Layer Centrifugation (SLC), and its effect on sperm viability. The viability was analyzed with regard to membrane integrity and membrane stability of ejaculated spermatozoa.

Trade was assigned as a Community responsibility at the founding of the European Community in 1957. It was then recognized that Europe would achieve a greater international influence if it were to negotiate trade deals with one voice. Since then, the basic rule has been that the European Commission negotiates agreements on behalf of the EC, and presents the agreements negotiated for approval in the European Council. Today, the 25-member European Union is the largest trading power in the world, and most member states have decades of experience of coordinating their national trade interests into a common position. However, partly as a result of the complex nature of the trade decision-making processes it is sometimes problematic to identify who or what really influences EU trade policy.

This essay is about a deserted medieval habitation called Skyttsie Hage which is located in the south of Sweden in the Scania province where it lies on a moor on the Falsterbopeninsula. Remains of five to six larger buildings have been found here with a surrounding earthwork, although it's not known for sure what kind of habitation they have been part of. Local folklore from the 17:th century states the area as a place where pirates lived, and that this was the reason for it's devastation. Another says that there once stood a breedingfarm belonging to the danish crown. Archaeologists have made several speculations which includes a deer park, a royal estate, an isolated farm or a smaller village.

This EEF-project is a part of a larger project at SLU, Division of Reproduction, Dept of Clinical Science, with the intention of developing and evaluating new methods for the assessment of stallion semen quality. Over the last 10 years there has been an increase in the use of artificial insemination with cooled semen in Swedish horse breeding. At the same time, foaling rates have decreased. This has lead to a need for new and better methods of assessing the quality of stallion semen. This EEF-project was based on an objective method to calculate motility, with QualispermTM, in fresh and cooled stallion semen, and after selection. Today sperm motility evaluation is mainly done subjectively by visual assessment with a light microscope, and the correlation between these motility results and fertility have varied.

Muskuloskeletala skador är ett stort problem hos hästar som tränas och tävlas i kapplöpning, och orsakar smärta med påföljande hälta för individen och ger även ekonomiska förluster inom industrin. Av dessa är stressfrakturer i tredje metakarpalbenet distalt på frambenet vanligast och utgången är ofta katastrofal med avslut på karriären och i vissa fall slakt. För denna typ av skada finns alltid en preexisterande patologi i benvävnaden. Träningen är högintensiv och kräver en fysisk adaptation av rörelseapparaten. Den kraftiga mekaniska belastningen kan kopplas till predilektionsplatser för frakturerna, där mikroskador i benvävnad utvecklas till fullständiga frakturer.

Opioider är vitt använt på smådjur som smärtlindring och för att minska behovet av anestesimedel. Opioider har också nyttjats på hästar så långt som 70 år tillbaka i tiden men användandet har varit begränsat och kontroversiellt då hästar lätt exciterar på grund av opioider. Metadon är en ?-receptoragonist och detta är den receptor som främst står för opioidernas analgetiska effekt. Metadon är inte godkänd för användning på djur i Sverige men används ändå ofta off-label på grund av sin goda smärtlindrande förmåga.

Opioidplåster avsedda för humant bruk används idag även för smärtlindring av djur eftersom det inte finns några registrerade veterinärmediciniska opioidplåster. För humant bruk finns plåster innehållande fentanyl och buprenorfin. Syftet med litteraturstudien var att granska studier i farmakokinetik och dynamik för att undersöka den vetenskapliga grunden för användningen av opioidplåster till djurslagen hund, katt och häst. Plåster kan vara ett sätt att administrera läkemedel transdermalt till den systemiska cirkulationen. Avsikten med plåster är att uppnå jämna koncentrationer i plasma (steady state) som varar under den tid som plåstret finns på plats, vanligen 72 h för människa. Vid användningen av fentanylplåster uppnåddes steady state hos människa efter 14 h.

Sarcoid is the most common tumor in horses all over the world. The sarcoid is a benign, locally invasive, usually fibroblastic proliferative skin neoplasm. Even if the etiology is not completley verified, the epidemiology and clinical behavior suggest a infectious intervention, probably BPV type 1 or type 2. However, it is known that the cause is multifactorial. A genetic prepdispositon has been identified associated to genes within the Major Histocompatibility Complex (MHC), but also to breed, age and perhaps gender.

Today most dosages used in horse medicine are based on studies in adult horses. Since there are differences between adult and neonatal horses with respect to different pharmacological parameters this can cause problems when administring drugs to neonatal foals. Neonatal sepsis is a common cause of morbidity and mortality in foals and aggressive antibiotic treatment is needed immediately when sepsis is suspected. In Sweden the combination of trimethoprim/sulphadiazine and bensylpenicillin is often used as the initial treatment. When administering drugs, interactions can occur between the drugs and endogenous substances.

Studiens målsättning var att besvara tre frågeställningar. Skiljer sig andningsfrekvensmönstret efter ansträngning hos varmblodstravare med prestationsnedsättning från normalpresterande hästar? Påverkas andningsfrekvensmönstret efter ansträngning av en ökad slemansamling i luftstrupen? Är koncentrationen surfaktantprotein D i blodet en relevant analysparameter vid utvärdering av nedre luftvägsproblem? Hypotesen var att travhästar med subkliniska luftvägsproblem i de nedre luftvägarna har en längre återhämtningsperiod efter ansträngning jämfört med friska hästar. Kopplingen mellan ökad slemansamling i luftstrupen och prestation undersöktes också. 24 varmblodstravare deltog i försöket. Innan försöket undersöktes varje häst kliniskt inkluderande vilo-EKG och luftvägsendoskopi.
