Introduction of heifers to an automatic milking system
Automatic milking systems (AMS) are part of a growing trend in Sweden and the number of milk-producing farms is decreasing rapidly. One main reason for the AMS is its ability to facilitate work for the farmer. The effects of introduction prior to calving have not been documented earlier and farmers are not in agreement, however they seldom see a problem with the introduction. The aim of this report is to find differences between two groups of heifers, where one group is trained i.e. introduced to the AMS before calving and the other group is introduced after calving.
Jämförelse mellan två olika plastningsprinciper, Cross Pac kontra konventionell plastning :
Baled silage has become one of the most important conservation methods in Sweden. Because
we take our grass as silage we get the quality and the good hygenic that we would like to
have. Silage has become a big buisiness also in the horse feeding where many of the breeders
have changed from the hay to the hay-silage. The difference between regular silage and haysilage
is that the hay silage is dryer (60-70%DM). The hay-silage has also put higher demands
on machinery and wrapping material since the grass gets sharper and harder to press together
real hard.
The main reason for the test was to compare two different systems for wrapping, the new
Cross Pac and conventional.
Djurskyddslagen och renskötseln
The aim of this literature review was to discern which legislations and regulations related to animal welfare that comprises reindeer and their significance in reindeer husbandry. The Swedish Animal Welfare Act (1988:534) was enacted July 1, 1988 and its main purpose is to ensure a good animal health and environment. Animals that live in a good environment with good health is considered to have good welfare, which can be described as an individual's condition in relation to its surroundings. Reindeer herding is an extensive form without daily management. In reindeer husbandry there are eight specific seasons over the year and reindeer are handled as they migrates between pastures, get earmarks, are sorted for transport and slaughter.
Anlockning och gnag av snytbaggar (Hylobius sp.) : effekt av plantstorlek och behandling med metyljasmonat
Two field experiments were conducted in central Sweden in order to: 1) Determine a relationship between the number of approaching pine weevils (Hylobius sp.) and the number of attacks by pine weevils, in relation to the size of seedlings of Scots pine (Pinus sylvestris). 2) Determine if application of methyljasmonate (MJ) on seedlings of Scots pine will result in higher resistance towards attacks by pine weevils and/or have any effect on the number of approaching pine weevils. The field experiments were designed with two separate parts in close vicinity on the same clear cuttings: a) pitfall traps placed in patches of scarified soil that caught approaching pine weevils at 2.5 cm from the bait, which consisted of different sized seedlings of Scots pine some of which were subjected to application of MJ and b) the same type of seedlings planted out in patches of scarified soil.
The first field experiment was conducted on a 1-year old clear cutting outside Uppsala in east central Sweden and the trapping part of the experiment consisted of 8 blocks with 6 treatments: 1) control, 2) small over-wintered seedling, 3) medium sized seedling, 4) medium sized seedling treated with 0.5 ml 100 mmol MJ 4 days prior to start of experiment, 5) large seedling, 6) vial with 9.5 ml of ?-pinene. The trapping experiment lasted for 6 weeks in the early summer.
Nytt ventilationssystem till djurstallar :
There is two dairy farms in Sweden with ability to be opened on both long sides, one outside
Hjo and the other one, Brandstadholm, north of Sjöbo. When there is no measures and results
or not enough literature about natural ventilation and especially on this kind of air inlet, makes
my tests very interesting not only on Alnarp, but among other companies.
I would like to find out if there is any air movements direct on the cows, how high/low
temperature, air humidity, light intensity and noise standard inside the barn. Does
Brandstadholm fulfil the rules and regulations when it comes to climate inside the barn? Could
this system become the new dairy barn instead of the conventional barns in Sweden?
I am going to focus on the animals environment, after all they are the one who is going to
spend the most of the time in the barn.
I used five electrical loggers distributed inside the barn to measure the temperature and one of
the loggers measured the air humidity, every 15th minute. One logger were placed on the
outside which measured both temperature and air humidity.
Från pre-human till post-human : Embryots reproduktiva status i skärningspunkten mellan stat och medicin
The aim of the thesis is twofold: the first aim is to identify a number of reproductive logics that are used to construct Swedish regulation of embryo donation for reproductive use as either ethical or unethical in the governmental ? and medical discussions ? and to examine how these logics are interconnected with notions of gender and parenthood. The second aim is to identify a number of tensions that arise in the application of the governmental ethical logic on the embryo and embryo donation and discuss how these tensions can be solved with a feminist material approach. I argue that the terminology used to distinguish between genetic, biological, social and legal parenthood in my material is insufficient for understanding the value of the embryo outside its pre-human status. I therefore argue for an embryonic feminist bioethics that is attentive to the embryos post-human status, and for a reformulation of the parenthood terminology in line with what I call ?reproductive ties?..
Klövhälsa registrerad vid rutinmässig verkning i lösdrift eller uppbundna system med ekologisk eller konventionell mjölkproduktion :
KRAV-certified organic dairy herds generally have a lower milk yield than conventional dairy herds. A high-level of milk yield requires a feeding regime with high amounts of concentrates, a factor known to contribute to the development of claw lesions (Bergsten, C. 2003). The aim of this study was to compare claw health between organic and conventional dairy herds in free and tie stall systems. The number of herds from different domestic animal health associations was chosen in proportion to the association´s total portion of Swedish dairy producing herds of each type, respectively.
Medarbetares skattning av chefers konflikthanteringsförmåga predicerar chefers självskattade emotionsreglering
Studien syftar till att underso?ka om de ansta?lldas skattning av chefers konflikthanteringsfo?rma?ga kan prediceras baserat pa? chefens emotionsigenka?nningsfo?rma?ga och sja?lvskattade emotionsreglering. Studien genomfo?rdes genom att 32 chefer utfo?rde ett datoriserat emotionsigenka?nningstest (Geneva Multimodal Emotion Portrayal Set) och en emotionsregleringsenka?t (Emotion Regulation Questionnaire). 181 medarbetare till cheferna svarade pa? en webbaserad enka?t ga?llande chefens konflikthanteringsfo?rma?ga (Conflict Resolution Questionnaire).
Personlig integritet och kreditupplysning
Most people would agree that privacy is a civil right, and that we should not be deprived of this civil right for other than legitimate reasons. The difficulty lies instead in how to decide where the legislative boundary should be drawn for the right to privacy, in order to protect the individual from an undue intrusion of his privacy. There are a number of areas where the right to privacy comes in conflict with opposite interests. One of these areas is credit report. In this master thesis the author discusses questions as, what is the meaning of the word privacy, and whether the protection of privacy is sufficient in the legislation concerning credit report? Also a comparative study of the Swedish and the English regulation is performed.
Utvärdering av ett större bergvärmesystem i en flerbostadsfastighet som har konverterats från fjärrvärme
This master thesis is an in-depth study of an existing heating system at a household cooperative in Uppsala that has been converted from district heating to a bedrock heat pump system. The study focuses on an economical system optimisation of the building?s complete heating system. The aim was to determine how well a heat pump system in large buildings actually work, find out possible ways to optimize the existing system and point out important system parameters for new heat pump installations in larger buildings.The project points out a possible energy cost reduction of 45 % without investment and further cost reductions with equipment investments. A reduction by 30 % is possible by improvements in the regulation system and 15 % is possible by maintaining the brine system.
Botulism hos svenska hästar :
Botulism is a serious disease with high mortality that can affect horses. Due to this about 20-30 percent of the horses in Sweden are vaccinated against botulism.
The purpose of this study was to see how common botulism is in the Swedish horse population and to se if a connection between feeding with haylage and botulism could be seen. In addition to this, the study aimed to find how common vaccination against botulism is among Swedish horses and on what grounds the diagnosis botulism is made.
Medical records of horses being diagnosed with botulism at all the major large animal hospitals in Sweden between 1995-2005 were searched. In addition to this the database where general practitioners report their cases as well as the cases with botulism reported to the insurance companies were included.
The results of this study show that only 0,03 percent of the Swedish horse population has been diagnosed with botulism during the time period this study covers. In all the cases included in this study the diagnosis was made based on clinical signs and in none of the cases verification by isolating the toxin was possible.
In all cases where forage is noted in the journals the horse has been feed haylage which indicate that there is a connection between the use of haylage and botulism.
Three horses died despite being partially vaccinated against botulism type B which indicate that a correct vaccination has to be done before the horse get any protection or that the correct diagnosis was not botulism type B..
Kalvars upptag av immunoglobuliner och specifika antikroppar från Locatim®
This master thesis was conducted in order to investigate the effects of the browsing
species Yeheb on animal tissues in Swedish landrace goats and to make a literature
review in order to increase the knowledge of the importance of this plant for livestock
production in Somalia. The evergreen Yeheb bush is a very important feeding source for
grazing and browsing animals in Somalia during the dry period. Yeheb contains
cordeauxiaquinone that stains the bones of the animals red/pink, which has been an
increasing problem when exporting meat to foreign countries. In an experiment, two
goats were fed dry and fresh leaves from the Yeheb bush for one and two months,
respectively. The goats did not feed the intended amount of dry leaves, since the supply
and palatability was not as high as estimated.

Detektion av mRNA från en cytokrom c gen belägen i genklustret för kloratmetabolism i Ideonella dechloratans
Abstract:In previous experiments with the bacterium Ideonella dechloratans a probable sequencecoding for a cytochrome c protein (cyt c) was observed, the sequence is assumed to have afunction in the bacterial respiratory chain. Detection attempts have been made to try to findthis protein, but have not succeeded. The purpose of this project is to detect the expressionof mRNA associated with the cytochrome c. And if it is detected, it will also be investigated ifthere is any difference in expression of the mRNA due to aerobic or anaerobic environment.Total RNA was purified from cultures grown under aerobic and anaerobic conditions. cDNAwas then synthesized using reverse transcriptase and subsequently amplified with thespecific primers in a qRT-PCR.qRT-PCR testing showed a distinct amplification of primer product, confirming that I.dechloratans expresses mRNA coding for the cyt c protein.
AI-diagnostik: Framtidens medicinska genombrott eller en risk f?r patients?kerhet? En kritisk analys av transparens och sp?rbarhet vid anv?ndning av AI-system f?r Alzheimersdiagnostik i svensk h?lso- och sjukv?rd: Samspelet mellan juridik och medicinsk in
Artificiell intelligens (AI) spelar en alltmer central roll inom v?rdsektorn och diskuteras flitigt f?r sin potential att utveckla v?rden genom f?rb?ttrad diagnostik och behandling. En ?kad anv?ndning av AI inom v?rden har potential att utveckla v?rdsektorn och vara svaret p? m?nga av de problem som h?lso- och sjukv?rden st?r inf?r. Med s?rskilt fokus p? Alzheimers sjukdom framtr?der AI som ett verktyg som kan m?jligg?ra tidigare och mer tillf?rlitliga diagnoser, vilket i f?rl?ngningen skulle
kunna f?rb?ttra m?jligheterna till v?rd f?r drabbade och bidra till medicinska genombrott inom demenssjukdomar.
