During an investigation of animal welfare in animal production, the focus has for a long time been focused on the absence of stress, suffering and injuries, and positive emotions have not been prioritized. However, in recent years that has been drastically changed. The public interest have increased for buying animal products from animals that have had a decent life, which have led to that play, exploratory behavior and other positive behaviours has come to play a significant role in welfare assessment. The welfare of cattle is difficult to assess since there is currently no ancestors to study, it is thus difficult to determine which behaviors can be regarded as natural and thus positively related, acordingly the welfare of cattle have been forgotten and research on positive emotions of cattle have not been prioritized.
The aim of this study was to observe which behavior growing cattle performe, and if there was any differences of which kind of behavior that was observed, if the cattle is keept on slatted floor or on a deep straw bedding. Furthermore, antoher purpose was to investigate if the observed behaviours indicate a positive, negative or natural welfare, and if it is possible to use the observed behaviours in a welfare assessment.
Methane production from dairy cows : relations between enteric production and production from faeces and urine
Methane (CH4) is a greenhouse gas (GHG) that contributes to the global warming. One of the largest sources of methane is livestock, preferably ruminants which alone counted for 30% of the total agricultural anthropogenic methane emissions in the year of 2000. The reason to why ruminants are such large contributors of methane are that the gas is produced in the rumen by enteric formation and leaves the animals by belching, exhaling or by the excreta.Diets high in concentrates can result in a lower emission of methane. Also diets with a high content of starch, such as alfalfa-grass, have a methane-decreasing. It is profitable to reduce enteric methane formation since that form of methane is unavoidably lost.
Eutanasi inom smådjurssjukvården; yrkesverksamma djursjukskötares upplevelser
The quality of health and care of our animals in the veterinary clinic is dependent on the veterinary nurse. Therefore it is important that the nurse has a good mental health and can provide this. Research shows that veterinarians are exposed to an elevated risk of suicide, moral stress, depression and anxiety. One of the factors contributing is believed to be exposure to euthanasia. The impact of euthanasia to veterinary nurses is yet unclear, as research focuses on veterinarians.
Light pollution : consequences and sustainable lighting design
Light has always fascinated humans but ever since the invention of the first light
bulb, the use of artificial lighting has accelerated dramatically. Darkness has never
been as rare as today and the overuse of lighting has created a new phenomenon
called light pollution. Most living beings are biologically dependent on the
recurrent twenty-four-hour rhythm of light and darkness, called the circadian
cycle. Human beings are evolutionary developed after this circadian rhythm and
the effects of constant artificial light is yet unknown. Scientists fear the consequences
of constant lighting and what it means physically, mentally and philosophically
for the human species.
Är djurskyddsanmälningar befogade? - en undersökning av djurskyddsärenden i Västra Götalands län under 2011
The aim of this paper was to study incoming complaints to The County Administrative Board in Västra Götaland during 2011 and examine if it was possible to see a connection between warranted and unwarranted complaints and informer, animal species and type of inadequate. In Västra Götaland, a complaint is classified as warranted if the inspection leads to a reprimand, whether it regards what was reported or not. Data were collected during three weeks through The County Administrative Board´s record system Platina and a total of 456 complaints were studied.
The parameter ?complainant? was categorized into four groups according to The County Administrative Boards own division; public with the subgroups anonymous and non-anonymous, animal health staff and others.
Klövspaltsinflammation : bakteriologi, terapival och möjliga anledningar till terapisvikt
Research concerning movement patterns of wild animals has been advancing since GPS technology arrived. But studying the snow leopard (Panthera uncia) is still difficult because of the harsh territory it inhabits in Central Asia. This study took place in south Gobi, Mongolia, and aimed to estimate the time spent at kills and the maximum distance away from kills between visits. Snow leopards were monitored with GPS collars that took a location every five or seven hours. Potential kill sites were established by identifying clusters of GPS-locations in ArcGIS and visited in the field for confirmation.
When does the protein profile in milk normalize after antibiotic treatment against clinical mastitis?
Concentration of protein in bovine milk is one of the most significant milk quality parameters, to a large extent determining the price for milk to the producer. Mastitis is a common disease among dairy cows, negatively affecting not only milk yield but also milk protein composition. Milk from mastitic cows tends to have lower cheese yield, negatively affected processability properties and sensory quality, due to changed protein quality and composition. Poorer milk protein quality would have an economically negative impact on dairy industry. Only few studies have investigated the short term effects of mastitis on milk protein composition.
Selection of habitat and resources during migration by a large mammal : a case study of moose in northern Sweden
Migration is a worldwide phenomenon that has occurred for thousands of years in a vast variety of species. The general knowledge of migrating animals is poor even though billions of animals from a range of different groups migrate every year. The human impact on migrating ungulates is high and many populations are declining globally due to direct and indirect causes. Hence it becomes vital to study the migration phase and the habitat and resources selected during migration. The objective with this study was to identify the habitat characteristics and resource selection of moose during migration and compare the selection between different seasons and utilization distribution (relative frequency distribution for the points of location of an animal over a period of time) categories.
Bibliotekariens val av informationsresurs. En studie av nio folkbibliotekariers arbete med tio referensfrågor
The aim of this thesis was to study librarians approach upon reference questions and available resources and also to find out if there is any connection between the nature of the reference question and the choice of resource. The purpose was also to give a deeper understanding of the reference work. Nine librarians were given ten reference questions and their reference work was tape recorded. The study was completed with seven interviews sent by email. Some of the reflections were translated under the headlines of form, subject, time, language and availability.
Seroprevalence of Rift Valley fever in sheep and goats in Zambezia, Mozambique and preparations for a metagenomic study of arboviruses in ticks
The virus-mediated disease Rift Valley fever (RVF) was discovered during an outbreak in Kenya in the 1930s. Since then it has spread to most parts of Sub-Saharan Africa, and in the last decades several outbreaks have caused economic and health issues in Africa, Yemen and Saudi-Arabia. The disease mainly affects domestic livestock, causing abortions, but is also a zoonosis. To be able to control the spread of the disease it is important with surveillance for better knowledge about the distribution and virus circulation even in inter-epidemic/epizootic
periods.
The human population is growing, and people and their livestock constantly move closer to areas with wild animals which act as reservoirs for different viruses. Also, humans and their animals often get within reach for arthropod vectors, hosting or carrying viruses.
Seroprevalence and risk factors for bovine brucellosis, salmonellosis and bovine viral diarrhea in urban and peri-urban areas of Kampala, Uganda
Africa is expected to go through a rapid urbanization over the next four decades and the demand for food is increasing in the rapidly growing urban and peri-urban (UPU) areas. Keeping livestock in urban areas is in particular associated with health hazards. This is due to close interaction between humans and animals, and it has been shown that zoonotic diseases are increasing in urban areas. The benefits of urban and peri-urban agriculture (UPA) are related to improved food security, in particular among low-income groups. Apart from the negative public health impact of zoonotic diseases, animal disease could have a devastating impact on the economy and food security of many households in these areas.
In the present study, three important endemic diseases, including brucellosis, salmonellosis and Bovine viral diarrhea (BVD), were analyzed in regard to seroprevalence and risk factors.
De medeltida djurfigurernas idévärld : med kyrkomålaren Johannes Rosenrods exemplifiering
In the medieval ruling catholic time the church walls was swarmed with programs of pictures with religious motives there the animal figures rich symbolics was significant first and foremost for the illiterate. Principally the inspiration comes from the antiquitys pagan world of fables and bestiary Christian world of symbols with the bible as the essential source. The essay describes six of the most common animal symbols who occur; dragon, the sneak in the Paradise, mouth of hell, lion, the fox as a preacher and the devil.To attain to a discussion about why just animals are used as symbols for human characteristics in the medieval church art instead for human beings as it's actually be about, I have studied bestiary and other literature about medieval churchpainting to get an understanding about the history of ideas about the thoughts of the time and about symbolics of animals, worth and how the Christianity have had an influence on the pictures.I have used Johannes Rosenrods church pictures from Tensta church in Uppland from 1437 as an exemplification but also mentioned other unknown painters who used similar animal codes and motives.It's plausible that the purpose of the animal figures was both religious and political, which was used by both the spiritual and the worldly authority so they could keep their dominance over the peasant. The figures was simple to read and remember and they made a deep impression on the people together with the sermon. The churchgoer get so to speak a sound- and image experience, a medieval reality who impress their world of ideas.When it's about the artistic formation of religious expression and characteristics it was undoubtedly a great advantage for the artists to use an animal code like a schemata.
Utveckling av tjänster för ett mobilt medium
The mobile revolution is here to stay, and today most people have (at least) one cell phone at home. Some even a PDA (Personal Digital Assistant)as a complement for the simpler tasks at the office, e.g sending e-mail, word processing, browsing the Internet etc. Many business have also given the employees the opportunity to do some of the business tasks inbetweeen customer visits with the help from a cell phone or PDA.Despite all this, the so called Internet connected mobile revolution is often mentioned as a big failure. Maybe because the people in general tended not to use the new technology as much as the companies predicted. This could be because they still haven't learned how it works, or just don't seem to have the need for services provided.After a couple of failures in the development process, almost every cell phone has support for mobile Internet today.
Effekter av transport och buller på grisars aktivitet samt aggressiva interaktioner i väntan på slakt :
During pre-slaughter handling of pigs the animals are often subjected to methods that induces stress and are a threat to the wellbeing of the animals, such as mixing of groups, loud noise and transportation. A new law will be implemented in 2006 in Sweden that prohibits mechanical noise exceeding 65 dB in abattoirs. The purpose of the research presented in this paper was to examine the effects of noise and transportation on pig behaviour. The activity and aggressiveness of the pigs were examined with behavioural studies during transportation and during three different noise levels: 55, 75 and 95 dB.
Before the noise treatments took place the groups were mixed and half of them were transported for approximately 2 hours. In the study 432 pigs were used.
