Erfarenheter av utedrift med köttdjur i Sverige och Kanada :

Beef cattle wintering outdoors should be provided a shelter, e.g. a type of barn or corresponding. This type of production requires appropriate soil types and secured animal welfare. For example, a clean and dry resting place needs to be provided to the animals. To receive an exemption for buildings the farmer has to have something equivalent that provides an adequate shelter.

Clinical and subclinical mastitis in dairy cattle in Kampala, Uganda

Dairy farming in Uganda provides a source of food, employment and income. Previous studies have revealed high frequencies of bovine mastitis, a costly disease for the dairy farmer. The aims of this study were to investigate the bacteriological panorama in milk from udder quarters with clinical (CM) and subclinical mastitis (SCM) and to determine the antimicrobial susceptibility in staphylococcal isolates. Further, we intended to establish the prevalence of subclinical mastitis and to investigate some environmental factors and animal properties that might influence the frequency of mastitis. For CM, farmers made contact with the members of this study when recognizing an animal with CM.

Behandlingsresultat av kliniska mastiter : en studie av mastitbehandlingar utförda i mjölkkobesättningen på Jälla naturbruksgymnasium 1997-2008

Mastitis is an important disease in dairy cattle. It is very costly for the farmers and affects a large number of animals. Few studies have been made investigating the outcome of treatment for acute clinical mastitis under Swedish conditions, and it can be problematic to use the results in foreign studies since both the microbial flora as well as treatments may be different from the situation in Sweden. In this project we have investigated data on clinical mastitis and antibiotic treatment in the dairy herd at Jällaskolan, Uppsala based on recordings during the last ten years. The material includes both Swedish Red (SRB) and Swedish Holstein (SLB) breeds, which have been kept at the farm under similar conditions.

Avlivning av sällskapsdjur, utförd av annan än veterinär : ett djurskyddsproblem?

We know that more than 2/3 of insured dogs in Sweden are put to death by a veterinarian, which means that almost one third are killed in trauma, lost or die in some other way. An unknown number of these are killed by their owner with no veterinarian involved. This graduate thesis contains a specification of the laws that control euthanasia of dogs and cats in Sweden, and the veterinary medical basics on how to perform euthanasia. The objective is also to give understanding on how pet owners choose to put their animal to death and why, and to discuss whether that is an animal welfare problem. It is legal to kill dogs and cats by shooting, using a sporting gun, provided that it is done according to laws and regulations.

Ligghall för utegångsdjur ? en sammanställning och analys av domar i djurskyddsärenden som handlar om ligghall till utegångsdjur åren 2007-2013

There is currently an ongoing discussion in Sweden about the need for weather shelter for farm animals being kept outdoors during the winter season. Currently, the national animal welfare legislation requires weather shelter providing the animals? with access to a dry and clean place to rest, but under certain conditions exemptions can be granted. The Swedish Board of Agriculture has put forward a hypothesis that there is a difference between judicial decisions in animal welfare cases dealing with weather shelters, as to whether the animal has shown to be suffering or not. The aim of the study was to highlight any weaknesses or difficulties when assessing animal welfare issues associated to the absence of or design of weather shelters.

Decision making and the role of empathy in animal ethics committees (AECs)

Ethical evaluation of scientific studies carried out using animals is legally mandated in many countries and has been so in Sweden for over three decades. The animal ethics committees (AECs) responsible for the task have however been subjected to criticism; common critique being that the wrong issues are discussed and that the ethical evaluation is thus incomplete, that there is a lack of coherence across committees and that the committees are not as democratic as they might appear. This study investigates the view of Swedish AEC members on a number of issues in order to shed some light on the mandate and functioning of the committees, and on the grounds for ongoing criticism. In a survey and interviews AEC members and other persons connected to the committees gave their views on the AEC task in relation to their roles, the ethical evaluation per se and whether or not emotions such as empathy play any part in it. There were significant differences found between AEC member categories and several issues were encountered, many of which have been stressed in previous studies.

Inverkan av utfodringsnivå och miljö på reproduktion och hållbarhet hos rekryteringskvigor :

This study is based on an earlier interdisciplinary study made by Redbo et al., (2000), Extensive cattle production systems ? out wintering, which lasted over two winters, 97/98 and 98/99, with two groups of heifers indoors and two groups of heifers outdoors raised in different environments, indoors or outdoors during their second winter. Both indoor and outdoor heifer groups were fed grass silage ad libitum throughout the experimental period that lasted from October until May. The objective of this study was to evaluate the long term effects of being raised in these two environments. This study includes data collected during the period lasting from the start of the experiment of Redbo et al., (2000) until the heifers had calved a second time and the results mainly deal with the performance of the animals after the experiment during their first two calvings and their first lactation.

Orsaker till mekaniska skador på nötslaktkroppar som uppstått under transporten till slakteriet eller på slakteriets stall :

In the Swedish abattoirs there are assistants that judge the slaughtered animals in regard to diseases and injuries. All diseases and injuries assign different codes. This master?s thesis is about code 42 which means injuries of different kinds like for example bruises etc. These injuries have risen during the transport from the farm to the abattoir lairage or during the stay at the lairage before slaughter.

Vad är lantbrukarens syn på länsstyrelsens djurskyddskontroll?

Indications on poor understanding for the animal producers situation from the inspectors of animal welfare control have been seen in papers from farmers interest organizations. The aim of this study was to investigate what farmers view is on the animal welfare inspections done by regional Swedish authorities as well as the animal welfare inspectors work. The study investigated whether or not there were any differences between different counties in Sweden. There were also questions asked to see what animal producers thought could change in the animal welfare inspectors work so it would benefit them. The study was conducted using a telephone interview questionnaire.

Val av liggplats och väderskydd hos dikor vid utedrift vintertid

If you keep cattle in a herd outside all year round on big varying grounds, their possibilityto perform their natural behaviour increases. This way of keeping cattle requires that youprovide them with their other needs, like shelter and a dry and clean resting place.According to the animal welfare authority´s regulations on livestock farming, only animalsthat are suited to stay outside during the cold season are allowed to be kept outside. Theyshould also have access to a shelter or another building that gives them protection from theweather and wind and provides a dry and clean resting place.Research has shown that as long as cattle do not get exposed to precipitation and wind theywill manage low temperature well. Some of the things that will affect how well the animalshandle different climates are the isolation ability of the fur, the animals´ body size and thefeed intake. A dry lying place that is both insulating and moisture absorbent is also of greatimportance.

Utvärdering av visuella observatörer förhålkameror och panoramakameror

SammanfattningExamensarbetet är utfört vid Fujita laboratory på Tokyo Institute of Technology.Detta examensarbete beskriver teori och bakgrund av en visuell observatör somhar forskats på vid Fujita laboratory.Att använda visuella sensorer, det vill säga kameror, kan bland annat hjälparobotar att agera autonomt i okända och i dynamiska miljöer. Syftet med envisuell observatör är att estimera ett objekts position i förhållande till robotensamt hur objektet och roboten rör sig gentemot varandra, med hjälp av bildensom fås från kameran.Syftet med examensarbetet har varit att studera teorin bakom observatören ochhur den anpassas till två olika kameror, en hålkamera och en panoramakamera.Fokus har legat på att utvärdera observatörerna experimentellt samt jämföra deolika kamerorna. Observatören för de båda kamerorna modelleras och simulerassedan och testas slutligen experimentellt. Examensarbetet innefattar även denbildbehandling som behövs för att göra experimenten möjliga att genomföra.I slutet av examensarbetet jämförs observatörerna för de olika kamerorna medavseende på korrekthet i estimering, robusthet mot parameterosäkerheter samtkänslighet för störningar.Resultaten visar att observatören för panoramakameran är känsligare förstörningar än den för hålkameran. Resultaten visar också att observatören förhålkameran är känsligare för parameterosäkerheter.

Finns Clostridium difficile i köttprodukter i Sverige? : en pilotstudie

Clostridium difficile is a grampositive, anaerobe bacteria with a spore-forming ability. The bacteria is present in the environment, can be isolated from animals and is common in hospitals, where it is a known cause of severe diarrhoea in compromised patients. Lately scientists have been discussing whether Cl. difficile could be a new food-borne pathogen. The bacteria has been isolated from food-producing animals and from meat products. In this pilot study 82 meat products, bought from swedish shops during a periode of four months, were investigated.

Ledpatologin hos 10 ungsuggor som uppvisat hälta och/eller förlamning

On average half of the sows in Swedish piglet producing herds are culledannually. A significant portion of the sows are euthanized because of lameness orparalysis. Young sows and gilts are overrepresented in the category of animals,culled due to injuries in the musculoskeletal system. These injuries cause pain tothe animals. Early culling of sows/gilts also have economical consequences forthe producers.

Utvärdering och jämförelse av olika fälttester för fotbollsspelare

Different field tests are currently used in a wide extent in different levels of soccer teams. To be able to assess the players? physiological status the tests must have high validity, reliability and external validity. Many different tests have been developt, but currently only five of these tests are most commonly used: Yo-Yo intermittent recovery test (YIRT), Yo-Yo intermittent endurance test (YIET), Multi-sprint-test, Beep-test and Cooper-test. Presently there is no definitive conclusion regarding which of these tests is most suitable for soccer players.

Den interaktiva djurparken / The interactive zoo

The purpose of this thesis project is to develop a set of interactive digital solutions designed to enhance the interest and knowledge intake of visitors at Skånes Djurpark (Zoo of Scania) in Höör. The project was carried out in collaboration with Skånes Djurpark and representatives from its visitors. Our thesis is based on academic works in the fields of interaction design, exhibit design and contextual learning. Ethnographical field studies have been conducted at Skånes Djurpark with additional field studies at Tropikariet in Helsingborg, Copenhagen Zoo and Regionmuseet Kristianstad. Existing information signs in Skånes Djurpark are primarily image- and textbased, forcing visitors to divert their attention from the different species of Nordic animals that inhabit the zoological park.
