Equine cutaneous melanomas arise much more often in horses with a grey coat color than in horses of other colors. Some scientists have in different studies come to the conclusion that the melanomas are neoplasms which can be classified by examining their histological and macroscopic features. The more defined and demarcated a tumor is, the more benign it tends to be. Other scientists believe that the skin lesions are the result of a pigmentation disorder that is linked to the greying of the coat color. According to this theory, the lesions are not malignant although they have the ability to metastasize.

Sub-lethal doses of neonicotinoids have been shown to negatively impact the health of honeybees. However, most studies to date have exposed bees only artificially to these pesticides under laboratory conditions. There have been just a few well designed and replicated studies of the impacts of realistic neonicotinoid exposure on honeybees foraging under field conditions. In order to close this knowledge gap, and to test the influence of the neonicotinoid clothianidin on honeybees, we used a study system of 16 paired, spatially separated (>4 km) spring oilseed rape fields in the south of Sweden. The fields were paired according to land use, the surrounding landscape and geographical proximity, using GIS.

This literature review describes organic pig production in Sweden, its advantages and disadvantages, but also how its problems can be reduced or solved. Organic pigs have the possibility to a more natural behaviour than conventional pigs. With outdoor pigs comes problems, especially during wintertime, concerning water and feed supply, thermal environment and supervision. Parasites and leakage of plant nutrients are other difficulties that comes with outdoor pigs. All problems and difficulties can be reduced or put right through correct management.

Objective ? To study the requirement of nursing care of the equine patient during eye treatment with a lavage system together with a constant rate infusion pump. Procedures ? Three veterinary nurses at ATG: s Hästsjukhus in Skara were asked nine questions at individual interviews. Inclusion criteria for participation in the interview were that the nurse should have treated equines with and without the infusion pump to the lavage system, but also traditionally with eye drops. Results ? The equine had a higher well-being since it experienced less stress during eye treatment with the infusion pump compared to treatment given by hand through the lavage system. The treatment would be more effective with constant rate infusion and save costs for the owner.

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.

This work reveals the results of BAL performed on horses included in a larger study that assessed the relationship of amount and type of inhaled particles in equine stable air on indices of respiratory inflammation in horses and people. During this study an unanticipated and marked elevation in lung eosinophils was detected in a number of the horses. The possible significance and cause of this pulmonary eosinophilia was investigated further, and is the main focus of the work presented.

Veterinary hospital care and advanced veterinary services are rapidly growing industries. As of January 1, 2010, veterinary nursing became a licensed vocation, the title of veterinary nurse became protected, and the act regulating competence among the professions of the veterinary field was extended. These changes, along with increased demands and expectations from owners, have given rise to greater demands on the staff's qualifications and have increased the need for well-educated staff with expertise in several different areas. The aim of this study was to find out what the licensed veterinary nurse can do in terms of rehabilitation for the hospitalized equine patient suffering from orthopedic injury. This has been carried out through qualitative interviews with veterinary surgeons experienced in treating such patients, and also by reviewing the relevant literature.

Penicillin G (benzylpenicillin) is the most commonly used antimicrobial substance used in equine medicine today. Two forms of penicillin G are available for equine use; one form is the poorly soluble penicillin G procaine and the other is the very soluble sodium salt. Although penicillin has a wide safety margin and is considered to possess a good tolerance, reactions due to side effects are sometimes encountered, which commonly is named ?penicillin-shock?. The etiology behind penicillin shock in horses is not completely understood, but the most common reason is believed to be procaine toxicity.

Twenty-four calves, which had not grazed previously, were divided into four groups. They were subsequently inoculated orally with either E. alabamensis oocysts, O.ostertagi/C. oncophora larvae, or both. One group remained uninfected and was used as a control.

EVA, Equine Viral Arteritis, was diagnosed for the first time in 1953 in USA. The disease gained international interest in 1984, when there were several outbreaks of abortion at Thoroughbred studs in USA. EAV, Equine Arteritis Virus, is an RNA virus in the Arteriviridae family. There is only one serotype of EAV but several strains and the strains have different virulence. EAV is transmitted in two different ways: by aerosols, or by venereal transmission.

The aim of this study was to document treatments of sick and injured reindeer in Tornedalen and the area around Gällivare. I also wanted to find out the basis for the treatments, how they are considered to work and if they agree with established veterinary science. The occurrence of ?folk remedies? was especially studied. In all, 40 reindeer owners were interviewed.

Respiratory disease with airway inflammation as main characteristic is common in the horse. It is a syndrome that is not yet fully understood. The etiology, pathogenesis and classification into different disease states are subjects for discussion and under continuous revision. Despite a number of modern techniques, the diagnostic procedure is challenging. There is no test considered to be gold standard when diagnosing these diseases.

American bison (Bison bison bison) is a new species in Sweden and was introduced in the year 2000. In this study the result of an interview and a field investigation is presented. The aim was to investigate the health and parasite status in Swedish bison herds. The most common reason to begin with bison breeding was meat production and/or sale of breeding animals and tourism. The Swedish breeder?s experience of bison is that they in general are healthy.

Equine appeasing pheromone (EAP) är ett feromon som avges vid juverområdet på ston under digivningsperioden. Detta feromon har framställts syntetiskt och ingår i produkten ConfidenceEQ som går att köpa receptfritt på apotek och kliniker. Produkten ska göra hästen avspänd och fokuserad och kan användas vid till exempel inlärning och träning samt vid situationer där hästen visar tecken på oro. Situationer där hästägaren själv kan välja att använda EAP är till exempel inför transport, veterinärbesök, hovslagarbesök eller tandundersökningar. Ibland kan detta vara situationer där veterinär sedan behöver sedera hästen för att det ska gå att genomföra vissa undersökningar och behandlingar. Det är därför intressant att undersöka om EAP påverkar sederingsgraden av detomidin, en vanligt förekommande substans för sedering av häst. För att undersöka om EAP påverkar sederingsgraden med detomidin hos häst utfördes en trippelblindad, experimentell, prospektiv, crossover-studie där 8 hästar ingick.

The interest in horses and equestrian sport is constantly increasing, and so is the will in both riders and trainers to learn more about the effect the rider and its equipment have on the horse. The last twenty years, more and more studies have been performed were the horse and its kinematics have been in focus. The access to more advanced technology has made it possible to study areas, which earlier have been hard to reach. The knowledge about kinematics in the horse, and how riders and their equipment interact with the horse?s movement, is also of great interest to veterinarians in equine practice.
