Horses are by nature herbivores, specialized on grass, and graze during the main part of the day. The horse has neither changed this basic behaviour nor the function of gastro-intestinal tract, when the horse was domesticated by man. A horse on pasture has an even production of saliva and gastric acids. The buffering effect of the saliva makes the pH in the stomach above four throughout most of the day. With abnormal long breaks of eating, the pH may decrease, causing an increased risk of gastric ulcer.

Skiascopy, also called retinoscopy, is a method for determining the refractive power of the eye. There are only a few, old studies made on equine refraction. The aim of this study was to investigate the refractive power in a population of Swedish horses. The study consists of a review of relevant studies done on animals and an experimental part where the refractive power of 93 horses of different age, breed and usage was examined. A pilot study of 12 horses was performed regarding the importance of cycloplegia when doing skiascopy on horses. The results of the pilot study show no significant difference in the skiascopy results between the group before and after cycloplegia were induced. Consequently, there is no need of inducing cycloplegia before doing skiascopy in adult horses. The study shows that horses usually were emmetropic (normally sighted) with minor deviations toward myopia or hyperopia.

The aim of this study was to find out how many and which of the herbs used for horses that have been scientifically studied with results to justify the use. In order to find out which herbs that are commonly used by horse-owners a phone interview was performed where six companies selling herbs for horses was contacted and asked to provide information on the most sold herbs for horses in Sweden. Devil's claw (Harpagophytum procumbens), chamomile (Matricaria recutita), dandelion (Taraxacum officinalis), nettle (Urtica dioica) and monk's pepper (Vitex agnus-castus) where the most sold herbs, followed by marshmallow (Althaea officinalis), burdock (Arctium lappa), marigold (Calendula officinalis), purple coneflower (Echinacea angustifolia/purpurea), cleavers (Galium aparine), licorice (Glycyrrhiza glabra), rose hip (Rosa canina), thyme (Thymus vulgaris) and vervain (Verbena officinalis), in no particular order. Of the most used herbs, research with focus on the use for horses was found for purple coneflower, licorice, devil's claw, monk's pepper, rose hip, thyme, and vervain. These studies did not cover the whole range of traditional use for the mentioned herbs, and more studies are needed to be able to claim that these herbs have, or have not, scientific support for use in equine management..

Icelandic horses are becomming increasingly common in Sweden. The owners of Icelandic horses in Sweden usually believe their horses to be different from other breeds. Icelandic horses are predominantly considered to be less reactive, less neophobic and easier to handle than other breeds. Swedish owners of Icelandic horses also usually try to house and handle their horses in a way similar to the traditional extensive Icelandic way. There are no scientific studies of breed differences between Icelandic horses and other breeds, or of the housing of Swedish Icelandic horses.

I Sociologiskt perspektiv på Hästunderstödd terapi studeras hur deltagares upplevelser och effekter av Hästunderstödd terapi med någon form av psykosocial inriktning kan förstås ur ett sociologiskt perspektiv. Fyra artiklar som behandlar Hästundersstödd terapi analyseras med ett konstruktivistiskt förhållningssätt och en induktiv ansats har antagits. Resultatet av analysen ställs i relation till tidigare sociologisk forskning och sociologiska teorier som behandlar interaktion, kommunikation och relation mellan människa och djur. Resultatet mynnade i tre kategorier som står i relation till varandra. Kategorierna är: Sociala relationer, emotionell utveckling och identitetsskapande.

Ridterapi har på senare tid börjat användas som en komplettarande behandlingsmetod för psykosocial problematik. I dagsläget finns ännu inte mycket forskning inom ämnet och behandlingsmetoden är vare sig speciellt känd eller etablerad. I denna uppsats görs en kartläggning av socialsekreterares uppfattning och kännedom om ridterapi. Undersökningen var i form av en enkät och genomfördes i Uppsala län där socialsekreterare som arbetar med placeringar på HVB-hem medverkade. Vi ville se om olika faktorer som exempelvis ett eget djurintresse, kunskap om behandlingsmetoden, kön och ålder kunde påverka deras inställning till ridterapi.

Syftet med detta examensarbete var att hitta praktiska metoder för att reducera innehållet av glukos, fruktos, sukros och fruktaner, så kallade lättlösliga kolhydrater (WSC), i vallfoder. Ett vallfoder med mindre mängd WSC kan vara användbart för hästar som har fång, är insulinresistenta eller har fått diagnosen EMS (equine metabolic syndrome) eller Equine Cushing?s syndrome. Faktorer som kan påverka innehållet av WSC i vallfoder är bl.a. växtens utvecklingsstadium, konserveringsmetod, lagringstid, tillsats av mjölksyrabakterier till ensilage/hösilage, samt blötläggning av foder innan utfodring.

Skiascopy is used to objectively determine the refractive power of the eye. Except for a Swedish study in 2007, where 93 horses of different breeds and ages were examined with respect to their refractive status, most studies on equine refraction were published about one century ago or more. The objective of this study is to examine the refractive status of healthy warm-blooded trotting horses. Skiascopy was performed in 117 horses in total, aged 3 days to approximately 22 years old. In a pilot study, it was determined whether young horses were able to accommodate or not during skiascopy. The horses in the pilot study were all younger than 14 months. In foals younger than 1,5 months we saw a significant difference in the skiascopy result in the right eyes before and after topical atropine was instilled, but not in the left eye.

The German equine housing system, HIT Active Stable?, are adjusted for keeping horses in groups, and are well establishes in Germany. Now the system attracts attention here in Sweden. The purpose of this study was to investigate if the horses have any be-haviours need of free access to roughages like straw or hay, after they have been visit the concentrate feeding station. A study was carried out at family Krohn?s active stables in Bönningstedt, Germany.

Syftet med studien var att explorativt undersöka vilken betydelse hästen har för brittiska soldater och veteraner som varit ute i krig och återvänt med någon form av ohälsa. Studiens frågeställningar var: Hur används hästen på Horseback UK  som en del i tillfrisknandet för brittiska soldater och veteraner som varit ute i krig? Hur beskriver brittiska soldater och veteraner som varit ute i krig hästens betydelse för livskvalitén? För att besvara frågeställningarna tillämpades en metod som bestod av kvalitativa intervjuer. Intervjuerna utfördes på Horseback UK i Skottland som är en välgörenhetsorganisation, skapad för att ge en trygg och säker miljö. De arbetar med hjälp av hästar för att hjälpa de som tjänstgör eller tjänstgjort i den brittiska armén och kommit tillbaka med någon form fysisk eller psykisk ohälsa.

This study examined constructions of horses and means staff working with horses parallel to therapy in institutional care ascribes to horses. A narrative method was used and the theoretical framework was social constructionism. A question was asked to the narratives: How can practice in institutional care be understood through these stories? The result showed different pictures of institutional care. Horses seem to provide a multi-faceted therapeutic tool.

Lameness localized to the hoof is a common problem in horses. Magnetic resonance imaging (MRI) as a diagnostic tool is becoming more common and is well suited for examination of the distal limb and the hoof capsule. Today there are two different methods of MRI where in one the horse is under general anesthesia and in the other the horse is standing and only sedated. In this study we have compared the visualization of the distal interphalangeal joint using these two methods in two different groups of horses with unknown clinical problems referred to two different equine hospitals. The width of the joint structures including thickness of joint cartilage and joint fluid and also the width of the dorsal pouch of the distal interphalangeal joint were measured.

As the number of inhabitants increases, the cities expand into the former rural landscape. The urbanization causes changes to the functioning of the peri-urban fringe. Land that previously was used for agricultural production is now used for alternative enterprises, as for example horse keeping and recreation. 75 % of all horses (approx. 200 000) are situated in the peri-urban fringe.

There is considerable variation between stallions in semen quality and fertility due to the fact that selection of stallions for breeding is not based on fertility or semen quality but on performance. The increasing use of cooled semen for artificial insemination has resulted in decreasing pregnancy rates. Therefore the equine breeding industry needs new methods for evaluation and development of sperm quality and fertility. This study is a part of such a project and is performed by SLU in cooperation with Flyinge AB. Ten stallions at the Flyinge National Stud were used in the study and three ejaculates were collected from each stallion.

Syftet med denna uppsats är att undersöka deltagares upplevelser av och tankar kring hästunderstödd terapi. Utifrån detta studerar vi hur hästunderstödd terapi är en del av socialt arbete. Detta har vi undersökt utifrån följande frågeställningar: ?Hur talar deltagarna om hästens roll och betydelse i den hästunderstödda terapin??, ?Hur beskriver deltagarna att hästens närvaro påverkar deras färdigheter och känslor?? och ?Hur upplever deltagarna hästunderstödd terapi som behandlingsmetod?? Studiens empiri härrör från intervjuer med fem deltagare i hästunderstödd terapi. Vi har gjort en kvalitativ studie med semistrukturerade intervjuer som metod för insamling av data.
