Sheep production is the only animal production in Sweden that is increasing. Therefore,increasing knowledge of the production is of great interest. In order to run a viable sheepproduction, producers needs to be successful in the breeding of the animals and achievean economic surplus in the end. Lambs that are born healthy and vital have greaterconditions to perform high lamb weight gains and thus a successful production. Thereare many factors affect the survival, birth weight and early weight gain of the new bornlamb.

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.

In 1993, Sweden signed the Convention on Biological Diversity and thus agreed to conserve our indigenous biological diversity. As a part of the convention, Sweden is obliged to conserve a number of domestic animal breeds and among them the Linderöd pig. In 1952, the zoo, Skånes Djurpark, took care of a pregnant sow that was regarded to be related to the old "forest pig". The old forest pig was thought to have been extinguished by the early 20th century as a result of the ban on boars not approved by state inspectors. However, according to later accounts, several farmers still kept some of these non-approved pigs.

Working as a veterinary nurse includes advising animal owners, helping them to make discisions through well-based facts and experience. Preemptive spaying of the healthy bitch brings many advantages and disadvantages. It leads to cessation of gonadal hormone production, and how the exact extent the surgery affects the dog is not yet fully understood. The sex hormones mainly control the reproductive system, but receptors of these hormones are found in many tissues of the body, and have complex relationships with other hormone systems. Spaying decreases the metabolism although the bitch gets an increased appetite, which enhance the risk of obesity, unless the owner restricts food intake.

After parturition the energy demand for milk production is greater then the energy provided from the diet. The cow mobilises therefore body tissues to compensate for the energy loss. Live weight and body condition scores decreases as a consequence of the mobilisation. The aim of this study was to analyse the relationship between body condition score, live weight and subcutaneous fat depth measured by ultrasound and the changes during the lactation. Possible differences between Swedish Holstein (SLB) and Swedish Red and White Cattle (SRB) were also investigated.

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.

Milk fat is an important feature in many different milk products and other foodstuffs and it is often crucial for the dairy plants that the milk fat is stable for different manufacturing processes. Lipolysis is the enzymatic degradation of fat and is the one of the causes for an elevated amount of free fatty acids (FFA) in milk. Further, the change in fatty acid (FA) composition in milk can affect the stability of the product and also the manufacturing process. Both internal and external factors, at farm level or at the dairy plants can affect both FA composition and content of FFA. Milking frequency (MF=number of milkings per cow and day) and the composition of feed are two examples of factors generally performed at farm level. The objective of the present study was to evaluate how FA composition of milk and amount of FFA are influenced by two different ingredients supplemented to concentrate.

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.
