A screening for Schmallenberg virus among sheep, goats and cattle in Zambezia province, Moçambique : and preparations for a metagenomic survey of virus in mosquitoes

As the world´s population increases and people's living conditions are improving, larger areas are needed for houses as well as food production. This means that new areas are exploited and that people, livestock, blood sucking insects and wild animals are forced to live close together. In combination with the global warming, leading to extreme weather such as floods and storms, this allows both new and old pathogens to emerge. The number of "emerging infectious diseases", EIDs, has increased in recent years and many of them have their origin in poor, tropical countries. Moçambique is therefore considered to be a high risk area for EIDs. Schmallenberg virus, SBV, was discovered in 2011 as an "emerging infectious disease" in dairy cows in Germany.

Självskadebeteende och riskbeteende för ätstörningar hos tonåringar: förekomst, samband och intervention med expressivt skrivande

The purpose of the present essay, as part of the project Self esteem and Life circumstances among teenagers, was to investigate the rate of both deliberate self-harm (DSH) and risk behaviour related to eating disorders in 14-year-old swedish adolescents, gender differences in DSH, and possible correlations between DSH and risk behaviours related to eating disorder. In addition, the effects of expressive writing (Pennebaker & Beall, 1986) on DSH and risk behaviours related to eating disorders were investigated. Data from two pilot studies are included. In total, 198 14-year-olds from four different schools in southern Sweden participated. For the purpose of measuring the rate of DSH, a simplified version of Gratz's (2001) Deliberate Self-Harm Inventory (DSHI) was used.

Social struktur och dominans hos hund

The dog (Canis lupus familiaris) is the first species ever domesticated. They can develop a close bond towards other dogs, almost like a relationship among siblings, which can be a high valuable resource for good relations and cooperation?s. Dominance in dogs is sometimes used to explain undesired behaviors and explained as a personality trait. Dominance though, is not a trait in a dog or a source for undesired behaviors, but can rather be explained as a relationship between individuals, were one of them receives more submissive signals from the other.

The movement of the rider?s hand related to the horse?s behaviour and the stride cycle

One way of signalling commands to the horse during riding is through applying tension on the reins to create bit pressure in the horse?s mouth (Terada et al., 2006; Clayton et al., 2011). The skilfulness of the rider in using the hands when applying bit pressure has consequences both for the horse?s performance and welfare (Manfredi et al., 2010). At the trot there are large vertical deviations of the horse?s body which the rider must adjust and adapt to (Terada et al., 2006) and an unsteady hand due to inability to follow the horse?s movement can be a source of discomfort and conflict behaviour in the horse (Heleski et al., 2009).

Konvergenskultur ? en medieteoretisk studie : En beskrivning av mediekulturens samtida tillstånd, utifrån populärkulturella och meningsskapande praktiker och dess ramverk knutna till nutida dramaserier

Drawing from the theoretical foundations of the ?critical theory? of the Frankfurt School and the media ethnographic ?cultural studies? approach of the british Birmingham School, this study attempts to sketch out a media theoretical overview of the contemporary state of media culture. Using the term convergence culture as the foundation, this study offers a theoretical background to the two contemporary streams that are the significant and distinct tendencies of convergence culture: intermedial convergence, its contemporary state and historical tendencies that can be traced back using the past media theoretical approach of the Frankfurt School, and cultural convergence, its contemporary state and historical tendencies, which lineage in a media theoretical context can be traced back to the british ethographic ?cultural studies? field. Using contemporary drama serials to identify and pinpoint these two stream, this study shows how intermedial convergence expresses itself today through media conglomeration in terms of branding, product placement and marketing as the result of the ?completed? convergence between screen culture and popular music as the current defining state of commodity culture.

Människans inverkan på hundar ? och hur det kan påverka arbetet inom djursjukvården

The aim of this study was to describe how body language of humans affects the domestic dog (Canis familiaris) and how it can be implanted in the stressed situation that occur at an animal hospital. The subject is brought to notice because the author has experienced that dogs can get more stressed when a stressed and nervous owner is attending. Humans affect each other through posture, facial expression, voice and movement, and are often driven by their emotions, which can differentiate the verbal communication from the non-verbal communication. This occurs both consciously and unconsciously. Every human uses body language but not everyone knows how it is used or how to understand it.

Bensimidazoler i Sverige : likheter och skillnader

Bensimidazoler är en flitigt använd bredspektrumverkande substansgrupp antiparasitmedel. I Sverige finns det fem substanser (albendazol, febantel, fenbendazol, flubendazol och oxfendazol) som används inom veterinärmedicinen, varav en är en pro-bensimidazol (febantel). Däremot finns endast en substans tillgänglig inom humanmedicinen (mebendazol). Syftet med detta arbete är att reda ut skillnader och likheter mellan dessa substanser. Fokus ligger på kemisk struktur, kinetik, aktivitet, spektrum samt resistensläget i Sverige. Kemiskt sett är bensimidazoler relativt lika varandra då enbart substitutet (d.v.s.

Rådgivning angående profylaktisk kastrering av den friska tiken

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.

Welfare impairment of lambs around weaning. Play and other behaviour indicative of affective state

The abrupt and early weaning of intensively kept lambs may have serious animal welfare implications, but relatively little is known about this. Weaning includes the breaking of the mother-young bond and abrupt replacement of milk by solid food, often coinciding with changes in the (social) environment. Altogether, these changes are likely to affect lamb welfare significantly. This study aimed to establish how strong and persistent lamb welfare is impaired following abrupt weaning by means of measuring behaviour parameters indicative of affective state. Also, we investigated the existence of a diurnal rhythm in play behaviour, which is considered an important indicator of positive affect and good welfare.

Grb10 and developmental programming: evaluation of a maternal diet restriction model during gestation

This study was conducted at the University of Bath, UK, from September to December 2014 as part of an ongoing research project aimed at elucidating how the Grb10 gene might act as a mediator of long-term health effects (such as predisposition to obesity, diabetes, coronary heart disease and hypertension) caused by environmental factors during development. This phenomenon is known as developmental programming. The purpose of this thesis was not primarily to answer any of the broader questions posed by this research project at large since this would require much more data than is reasonable to acquire over the course of a few months, but rather to evaluate the methods used in this project and reveal whether they are working the way they are presumed to. In the research project, which employs mice with the Grb10 gene knocked out as well as wild-type control mice, a dietary restriction model is utilized during gestation, which is supposed to generate offspring with lower birth weight and subsequent detrimental health effects in adulthood. This is supposed to be achieved by restricting the protein content of the pregnant mothers? diet to 9 % (as opposed to the control diet of 20 %) throughout gestation.

Avvikande repetitiva beteenden hos hund : bakomliggande orsaker och konsekvenser

Stereotypier och tvångsbeteenden är relativt vanligt förekommande hos hundar. Exempel på några av dessa beteenden är flanksugning, filtsugning, slickdermatit, bita i luften, svansjakt och att stå som fastfrusen. Det finns oenigheter inom litteraturen om vad en stereotypi respektive ett tvångsbeteende är. Vissa författare använder begreppen som synonymer, medan andra ser det som två skilda beteenden. På grund av den rådande begreppsförvirringen använder jag termen avvikande repetitiva beteenden som ett samlingsnamn.

Positive reinforcement training for laboratory mice

The mouse (Mus musculus) is the most commonly used mammal in biomedical research and can easily be restrained by both hand and by a device. Restraining animals causes stress that not only decreases the animal?s wellbeing, but may also influence the research results. The first aim of this study was to train mice to voluntarily stand still using positive reinforcement training. Another benefit of teaching a mouse to stand still is that you can avoid anaesthesia for some procedures.
