Tillfrisknande och användning av hästar med fång :

Laminitis has crippled horses through times and many cures have been used to treat it. Since the mechanism of the disease is yet not fully understood, treatments are only ways to alleviate the pain and at best, slow down the pathological process enough to make time for improvement. This paper is a retrospective study of 71 horses treated by a protocol at Hästsjukhuset Strömsholm. The protocol implies three visits at zero, five and fifteen weeks. At each the horse is evaluated and treated by a veterinarian.

Jämförelse av vertikala krafter mellan hov och underlag vid nedsittning och lättridning i trav hos häst :

Equestrian sports and the interest in horses have existed for hundreds of years. It is only in the last thirty years the technological development have enabled closer studies of equine locomotion. The production of both soft- and hardware that manages to capture and analyze the fast movement of the horse has resulted in a large increase in locomotion research. Even though the interest in horses and the different disciplines they compete in is great, there is a small understanding in how the rider influences the movement of the horse in different types of training. There are several studies available where horses moving freely without the influence of a rider have been studied. What happens with locomotion and ground reaction forces when a rider and equipment are added is not well studied. The objective of this study was to investigate if there are any differences in the ground reaction forces between sitting and rising trot. The study contained seven horses. Six Grand Prix dressage horses and one dressage horse competing at intermediate level.

Genetic study of cryptorchidism in Swedish Icelandic and Standardbred horses

Samodling är en odlingsmetod som kan användas för att förbättra dagens odlingssystem. Metoden innebär att två eller flera kulturer odlas tillsammans under en större del av växtsäsongen. Samodling kan användas på flera olika sätt för att förbättra odlingsförhållandena för antingen huvudgrödan eller hela odlingen. Den har en bevisad effekt på olika skadegörare och kan minska angreppen i odlingen. Samodling kan även användas för att minska ogrässpridningen, förbättra mikroklimatet, samt öka antalet maskar och naturliga fiender i odlingen.

Itrakonazol till häst : en farmakokinetisk möjlighet?

Itraconazole is a third generation azol, a fungicide which acts by inhibiting ergerosterol synthesis in the fungal cell membrane, and thereby disturbing fungal regeneration. It has proven to be less toxic, to have a broader spectrum of activity and to be more potent than its predecessor ketoconazole. Itraconazole is only available in therapheutics approved for human use. Pharmacokinetic studies has been performed in humans, dogs, cats and laboratory animals. Although itraconazole has been used tentatively with good effect against fungal infections in horses, no pharmacokinetic studies have yet been done.

Aortainsufficiens hos häst : patofysiologi och behandling

Aortic insufficiency is a very common valve problem in horses and most often affects older individuals, but nevertheless existent within younger ones. The root cause for aortic insufficiency can be varied, for example; endocarditis, ventricular septum defect or congenital valve disease but the most common are progressive valve degeneration or elite competition. Depending on the root cause, different changes can be observed on the aorta valves, but they do all have the same effect, the valves do not seal properly and blood leaks backwards. Many horses can, even with this deficiency, perform highly without any visible impacts and there is therefore no need to treat those subjects. Most often the symptoms arise at a later stage in life and they are, more often than none, put down for other reasons. In the occurrence of the clinical symptoms showing, treatment guideline is to inhibit these symptoms since the valve degeneration is presently irreversible.

Utfodring i finmaskiga hönät : hästens ättid och skötarens arbetsmiljö

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.

Fördelning av frambensskador på ytliga böjsenan hos galopphästar :

Superficial digital flexor tendon injuries are common causes of premature retirement or pre-longed convalescence periods for race horses. The curve gradient at Täby Galopp race track is very small and most races as well as high speed training are done on the left rein. It is believed that the horses left foreleg is under considerably more strain then the right foreleg when being ridden on the left rein during gallop at high speed. During gallop on the left rein the horse puts its entire weight on the left foreleg when regaining ground contact. The purpose of this study has been to find out, through analyzing the statistics concerning the horses that visited the ATG clinic at Täby during a period between January 2003 and September 2006, whether there is a higher frequency of superficial digital flexor tendon injuries on the left leg rather than the right and if so, can this support the theory that the design of the race track in combination with continuous left rein races can be a contributing cause of these injuries. The result of the study shows that 57% of the tendon injuries occurred on the left front leg and 38% on the right front leg. The difference is not large enough to support the above theory of the underlying cause of these injuries..

Den svenska varmblodiga hästens avelsmål : en enkätundersökning och analys av genetiska trender

As the quality of internationally competing horses is increasing, a debate concerning the breeding goal of the Swedish Warmblood horse has arisen. Some people claim that the breeding goal should be divided into two separate goals in the future; one for show jumping horses and another one for dressage horses. At the same time others claim that since the largest group of people using the Swedish Warmblood horse today is amateur riders, the needs of these riders should be taken into a larger consideration in the breeding program. The largest emphasis in this matter is on the horses? temperament. The objective of the study was to investigate what the majority of the Swedish horse people think about a variety of questions concerning today?s breeding goal of the Swedish Warmblood horse.

Hästhållningen i Ängelholms kommun - ur hästens välfärdsperspektiv

An interview study of horsemanship has been conducted in the community of Ängelholm. The study is part of a larger project, where a further four students who are writing their thesis? have conducted interviews in Lerum, Hässleholm, Nyköping and Enköping, a total of 52 horse holders in 5 different communities. The collective results are summarised in "Hur hålls hästarna i Sverige och vilka är motiven" by Catharina Svala. The purpose of this larger report has been to examine why Swedish horsemanship is the way it is today through communication with the various horse holders.

Uppkomst av metaboliska rubbningar hos häst under tävling i distansritt ? omvårdnad och förbyggande åtgärder

During an endurance riding competition the onset of metabolic disorders leading up to elimination from the race are common. As many as 8,7 % of the horses participating in international endurance riding competitions are eliminated due to metabolic causes such as tachycardia, absence of borborygmi, hyperthermia and dehydration. To prevent the onset of metabolic disorders in the horse the rider must be able to determine the physiological and physical status of his or her horse. This requires good knowledge in nutrition, physiology and performance training. The risk of developing metabolic problems is reduced through the right feeding management and training.

En kvalitativ utvärdering av det accelerometerbaserade hältdetektionssystemet ?Lameness Locator? :

Background: Evaluation of lameness in horses is traditionally performed by a veterinarian who subjectively evaluates the movements of the horse. Accordingly, lameness diagnosis varies with the veterinarian and circumstances for which the horse is examined. Research within the area has long tried to establish an objective and standardized method for lamenessevaluation in horses. Several methods have been shown to be reliable and are used regularly within research, for example measurement of forces between the hoof and ground, and measurement of movements with high speed cameras or accelerometers. However these methods require considerable preparation, standardization, and expensive equipment as well as produce large amounts of data that are incomprehensible for the clinician.

Ryttarens tygelsignalers inverkan på hästens beteende och trycket i tyglarna

This essay derives from the concern that horses ridden with a bit in their mouth can be subjected to strong pressure from the bit if the horse and rider do not understand each other. The horse's mucosa membrane and the tongue are very sensitive tissues (Cook, 1999; Manfredi, 2005; Oliveira, 2005; Terada, 2006) and the bit can then be a source of pain and discomfort. The training of the horse should therefore always be a step by step process and as the horse develops difficulties are increased. Oliveira (2005) suggested that high demands can be placed on the horse but to be successful in the training it is essential to be content with small progress and reward the slightest desired response from the horse. This corresponds with the principles of operant conditioning with negative reinforcement.

Kan kombinationen av dehydrering, kronisk stress och/eller endotoxemi vara orsaken till träningsinducerad lungblödning?

Thoroughbred racehorses have suffered from exercise-induced haemorrhage for over 300 years. Almost all competing horses develop exercise-induced pulmonary haemorrhage (EIPH) at some point but most horses don?t suffer from reduced competing capacity due to the disease. The cause of the exercise-induced haemorrhage is unknown. The most believed theory today is that EIPH is induced by pulmonary stress failure caused by pressure over 100 mmHg in the pulmonary arteries during exercise.

Krubbitning hos häst på olika strömaterial :

By limiting our horse?s freedom of movement, we restrict their opportunity to forage, which is one of their most important needs. If their need of forage is not fulfilled it can lead to frustration, which might manifest itself in abnormal behaviour, like the oral stereotypies for example crib-biting. It is a held belief that the horse swallows air while crib-biting, which they don?t, and that swallowed air causes colic, and the belief that other horses can copy the behaviour, leads to the use of many methods to prevent the behaviour.

Örter som fodertillskott till häst : populärt komplement utan risker?

In the Swedish market, there is a wide selection of herbs as supplement to the horse´s feed. A trend today is that many companies are marketing herbal remedies with allegations of medical effects. If you want to sell the product for that purpose it must be verified and approved as drug or natural remedy by the Medical Products Agency. Some herbs may contain active substances. Nevertheless, only a few studies have been conducted on single herbs to investigate safe doses for horses.
