Klövviltets nyttjande av foderraps på viltåker och betespåverkan på angränsande skog
Today we have more game species than ever before in our landscape, both regarding number of species and number of individuals. The increasing number of wild species is an increase in game recourse for the countryside. The increase of game species, however, has negative effects on forests and agriculture land. The negative effects for forestry are damages on economic important trees, due to losses in production and quality. However there are ways to decrease the damage on valuable and important trees.
Unga grisars sociala beteende : hur uppfattar de varandra
Studies on wild boars have shown that piglets at 10 to 12 days of age can be introduced to pigs outside the litter without fighting. In today's production systems, the litters are kept in separate pens until weaning. At that point, the litter is divided and the piglets are placed together with piglets from other litters. This usually leads to aggressions among the piglets and may cause stress. This literature review aims to find out how piglets perceive other pigs in their surroundings.
AUSTERS 1:61 - ett fritidshus på Gotland
A few hundred metres from the beach on Fårö, Gotland, is a small lot with pine trees, green moss and wild fl owers situated, owned by my brother and sister. Eventually they would like tobuild a summerhouse here, in close proximity to their relatives. My project is a proposal for the summerhouse at the site, within the restrictions of 61 m² building area, with focus on interior,exterior and the environment.My proposal is a house close to the surrounding nature, with reference to the the building tratition on the island and with local materials. Orientation to the sun, road and neighbours hasall infl uenced my ideas of this house and the relation between inside and outdoor living, were important in my creative work. The aim was to create a house made for the family and theirholiday lifestyle and allowed consideration for the possibility of a growing family with more children.
Miljöfaktorers påverkan på ornelukt
SAMMANFATTNING
Sedan lång tid tillbaka har hangrisar kastrerats för att undvika ornelukt, en fekal-urinliknande
doft som uppkommer i galtkött vid tillagning. Kastrationen är smärtsam och forskarna letar nu
efter alternativ till det kirurgiska ingreppet. I denna litteraturstudie har jag valt att fokusera på
hur man kan hindra produktion och upplagring av orneluktsämnena androstenon och skatol i
subkutant fett genom att förändra grisarnas miljö. Stallhygienen har visat sig ha betydelse för
ornelukt där smutsiga grisar har betydligt högre halter skatol i subkutant fett än rena grisar.
Även ljus och temperatur har en inverkan på orneluktsämnena. Höga temperaturer och korta
ljusperioder ger ökade halter av androstenon och skatol.
Slaktsvins basala behov i kommersiell uppfödning : Slaktsvins basala behov i kommersiell uppfödning oönskade beteenden, skador och välfärdspåverkan
The Swedish Welfare Act § 4 says that "Animals must be kept and cared for in a good environment for animals and in such a way that promotes their health and allow them to behave naturally." Pigs in the wild spend 80% of their waking hours walking around and rooting for food, eating and exploring their environment with its snout. Fattening pigs in commercial farms spend 80% lying doing nothing. A lactating sow is lying down most of her day, and only 10-20% of the body surface is in contact with the floor, so the pressure is high on these spots. Piglets lie down and paddle with their legs, with high liquid content in the tissues, several times an hour, to stimulate and massage the sow's udder. In the existing system, these individuals are held more often on floors that are anything but inviting to sleep on.
Variation in fattening pig exterior, gait and weight gain in commercial organic herds
Pigs in Swedish organic production systems have been shown to have more findings of arthritis at slaughter, compared to pigs in conventional pig production. With this in mind a study was performed, to primary, investigate variation in exterior, gait and weight gain between sire breeds and, secondly, to investigate variation between herds, season, gender, age and assessment occasion on these recordings. Swedish commercial hybrids, crosses between Norwegian Landrace and Swedish Yorkshire were inseminated with either Hampshire or Duroc as terminal sire. All the pigs had known pedigree as each semen dose contained sperms from one individual boar. All piglets were individually tagged closely after birth, and exterior and gait assessment were performed at two separate occasions, early and late during the fattening period.
Serum Amyloid A as a possible marker of health and disease in non-domesticated mammals : a retrospective pilot study of SAA levels in dolphins, elephants and tapirs at Kolmården Wildlife Park
The veterinary handling of wildlife, both in zoos and in the wild, commonly requires that the patients need to be captured and immobilized for examination or treatment. This emphasises the need for quick, on-site, laboratory equipment, in order to minimize the analysis time and thus the stress for the animal and also in order to increase the possibility of starting relevant treatment early on.
The aim of this pilot study was to determine whether Serum Amyloid A (SAA) could be a measured in blood samples from bottlenose dolphins (Tursiops truncatus), Asian elephants (Elephas maximus) and South American tapirs (Tapirus terrestris). SAA rises to its maximum about 24 hours after the introduction of an inflammatory agent in companion animals. This also correlates with the estimated time it takes for animals at Kolmården Wildlife Park to be examined and having blood samples collected after being observed as sick. The study also evaluated whether the Eurolyser SOLO, using a turbidometric immunoassay (TIA) developed for human diagnostics, could be used for such analysis.
This pilot study was a retrospective analysis of SAA in convenience sampled frozen serum, collected from dolphins, elephants and tapirs.
Gustav Vasa-monumentet i Gävle : en historiebruksanalys
On the 12:th of April 2011, the Swedish tabloid magazine Expressen publishes a story, claiming that Ola Lindholm, presenter of critically acclaimed TV-show ?Wild Kids? has been suspected and apprehended on cocaine allegations. The serious allegation called for Ola Lindholm to defend himself against the allegations. His only public response was a blog-post where he claimed his innocence, albeit with some reservations. The purpose of this paper is to analyze Lindholm?s rhetorical defense.
Attityder till återintroduktion av visent i Sverige
The European bison is a species which is no longer present in the wild fauna of Sweden. Reintroduction has been proposed in several different forums. Reintroduction is an attempt to reestablish a viable population of a species in an area to which it is native. To make such an operation successful in the long run it is essential to know the attitudes of the stakeholders involved. This study has sensed the attitudes towards reintroduction of European bison to Sweden.
Expression and Purification of Murine Tripeptidyl Peptidase II
Tripeptidyl peptidase II (TPPII) is an exopeptidase which cleaves tripeptides from theN-terminus of peptides. The exact functional role of TPPII is still a matter of investigation. Itis believed that the enzyme is primarily involved in intracellular protein degradation, where itcooperates with the proteasome and other peptidases to degrade proteins into free aminoacids. These amino acids can subsequently be used in the production of new proteins. The aimof this work was to express murine wild type TPPII using E.
Beatrix Potters kaniner : verklighet och fantasi
This master thesis deals with questions concerning facts and fiction in the world of Beatrix Potter's rabbits. The purpose is first and foremost to find the connections between the pet rabbits, that she used as art models, and the rabbits that came to life through her "tales".The method has been to gather facts through biographic reading, and to analyse Beatrix Potter's rabbit tales, using tools developed by Swedish picture book experts. The rabbit characters are thoroughly examined and so are the settings where the tales take place. Matters concerning Beatrix Potter's painting technique and illustration style as well as her literary and pictorial inspirations are dealt with.Conclusions are, that the fictive rabbit characters have indeed a lot to do with the fact that Beatrix Potter was interested in natural history and studied animal behaviour and anatomy in detail. For a long time rabbits, both wild and domesticated, were her favourite study objects which provided conditions for her rabbit fantasies.
Uppfödning av okastrerade hangrisar - ett alternativ till obedövad kirurgisk kastrering av smågris
Pigs kept for meatproduction are often surgically castrated to prevent aggression and boartainted meat. Castration without analgesia and anesthesia is painful and causes a lot of stress to the pig. There are alternatives such as to surgically castrate the male pigs with analgesia and/or with anesthesia, immunocastrate or keep them as intact males. In Sweden the most common practice is to surgically castrate the pigs before they are seven days old. The impact on the pig is that the incision causes pain and stress, which may lead to changes in behaviour, reduced appetite, reduced growth and a higher risk of infections.
Immunokastrering av hangrisar :
Active immunization against gonadotropin-releasing hormone (GnRH) is an alternative to surgical castration of male pigs to avoid boar taint. The aim of this study, including 128 pigs, was to evaluate the effect of a GnRH-vaccine Improvac® on performance and on social and sexual behaviour. Male pigs were assigned to three treatments; surgical castration at four days of age, immunization against GnRH and no castration. Vaccination was performed eight and four weeks before slaughter. Surgically castrated male pigs had significantly lower daily weight gain during the suckling period than entire male pigs (235 vs.
Studie på beteendeförändringar hos katt efter behandling av Feline Odontoclastic Resorptive Lesion (FORL) :
Feline odontoclastic resorptive lesion (FORL) is a tooth disease
affecting both domestic and wild cats. Although FORL was
described as early as the 1920´s, the etiology is still unclear. Several
hypotheses have been presented but different studies have obtained
contradictory results, and today there is no generally accepted
etiology. Teeth affected by FORL are characterized by root
resorption with progressive destruction of the tooth structure and
alveolar bone as a consequence of clast cell activity. The disease is
considered very painful when reaching a certain stage.
Drömmen om The West : Bildanalys av företaget Swansons kataloger från 2002 och 2009
This study has been about the representation of the Swedish tourism company Swanson?s. They do trips in US and every year they do a brochure with many pictures. The objective of my study is to look how pictures help to constructs places. Its often problem with pictures because sometimes they are constructs.
