Kortare sintid ? hur påverkar det kons mjölkavkastning, metabolism, hälsa, hull och vikt?

A shorter dry period length has in studies abroad showed some positive effects among high yielding dairy cows. Among other things it has been suggested that the periparturient metabolic stress becomes lower, that the fertility is improved and dry off becomes gentler for the udder, due to a lower milk yield. The milk yield is generally reduced during the first period after calving, especially among primiparous cows. The aim of this master thesis was to investigate how Swedish cows were affected by a shortened dry period, regarding milk yield, metabolism, health, body condition and body weight from two months before calving to some weeks after calving. Also plasma concentration of lactose during the period before calving was determined.

Metoder för att beskriva kumulativa effekter med avseende på biologisk mångfald och vägar :

Cumulative effects are seldom treated in Swedish Environmental Impact Assessments (EIA). This report treats these questions and which procedures and methods that can be used when assessing cumulative effects in EIA. This report is a literature study where also a case study is a part. The case study shows how existing methods for cumulative effects can be used in practice. The report is concentrated on biology and treats cumulative effects on premises of biodiversity and roads. Cumulative effects include both direct and indirect effects.

Analys av juverhälsodata från kärnbesättningen Viken :

Nötcenter Viken is a Swedish nucleus herd for dairy cattle. The goal for the farm is to select suitable mothers for the next top generation of bulls. Today the selection for udder health is based on a pedigree index and phenotype data. The pedigree index is based on the cow?s father and grandfathers breeding values.

Nya renings- och uppgraderingstekniker för biogas

Biogas is a renewable energy source that is produced by anaerobic digestion of organic mate-rial. In Sweden, biogas predominately comes from sewage water sludge and landfills or from organic waste of households and industries. Small scale digestion plants at farms are espe-cially expected to contribute to increased biogas production in the future. Biogas can be ob-tained directly in it?s raw form and used as fuel in a combustion chamber.

Den geografiska, funktionella och processorienterade organisationen : en fallstudie av Holmen Skog, SCA Skog och Sydkraft Vattenkraft

This thesis reports on a case study of two different organisational forms in the Swedish forest industry; the geographic and the functional organisation. The work in the geographic organisation is carried out within districts under the supervision of an overall responible district manager, where as in the functional organisation the work has been divided into functions headed by function managers. Forest magement, logging and wood purchases are examples of such functions. The general idea of the functional organisation is having the functions working over a larger geographic unit, without subdividing district boundaries of the region. Also a third organisational form of current interest for the forest industry; the process orientated organisation, is analyzed in the case study. Here, a company outside the forest industry has been analyzed, since no forest company was considered to have made as much progress of changing organisation to process orientation. In the report I present the results from qualitative interviews, where I give the reader a picture of the motives behind each organisational form, what the form implies for some of the company?s interested parties and the organisations? views on future organisational development.

Kalvutdragaren - en hjälpande hand? :

The calf extrator?s function has been studied, through measuring traction and how this varies in different situations, in comparison with corresponding manual traction situations. This was done against the background that excessive force at assisted calvings at dystocia can mean life threatening damages on the calf such as grave acidosis, vertebral fractures, femur fractures and rib fractures. The calf extractor has earlier been measured to pull with greater force than the established maximum force of ?two strong men?.

Vilka faktorer påverkar ett mjölkföretags tillväxt? : en jämförelse mellan Sverige och Danmark

Dairy farms have during a long time been under pressure and this situation was aggravated during the spring and summer of 2009, when profitability declined to historically low levels. Lower milk price and relatively high input prices have caused Swedish dairy farms great liquidity concerns and profitability problems. For a long time, Denmark has been identified as a leading country for the agrarian development with a leading structural rationalization and willingness to grow. In 2009, it was shown that the Danish agriculture, which is generally more leveraged, has difficulties in maintaining profitability and when market price of land started to fall, the proportion of technically insolvent agricultural enterprises rose dramatically. In light of this prevailing situation, this study highlights differences between Denmark and Sweden with the hope to learn from each other.

Allt som finns kvar : Om personarkiv hos föräldrar som förlorat små barn

The object of this two years master's thesis has been to study a specific genre of personal archives by examiningthe archives of nine parents who have lost one or several infants. Using internet-based methods, (e-mail, Skypeand digital photographs), I have conducted qualitative research using a general interview guide technique. Usingresearch from archival theory as well as other fields, my material has been arranged and analysed according tothemes and recurring thoughts picked up from my informants during the interviews.My main theoretical aid has been that the role of parent who has lost a child is the starting point for the creationof the personal archives. Another important theory is my definition of the term ?document? as not dependent onmedium and format, but on usage: if an object has been used as a part of an archive, it is a document.

Kvinnors våld mot kvinnor. En jämförande studie av könsmaktsanalysen och våld i lesbiska parrelationer.

AbstractFokus för denna uppsats är våld i lesbiska parrelationer och hur man teoretiskt kan konceptualisera detta våld. Mitt övergripande syfte har varit att öka förståelsen för denna form av våld och därmed bidra till ett relativt outvecklat forskningsfält. Ett ytterligare syfte har varit att undersöka om den könsmaktsanalys som haft stor betydelse för tolkningen och förståelsen av mäns våld mot kvinnor i heterosexuella relationer även kan förklara våldet i en lesbisk parrelation. Fokus för min analys har dels varit om och i så fall på vilket sätt kön är en faktor som kan förklara det lesbiska relationsvåldet, dels om en förståelse av våldet inom en könsbaserad teori kan innebära en viss problematik. Jag har även undersökt andra faktorer som heterosexism och homofobi och dess betydelse för våldets uppkomst och former samt mer individrelaterade förklaringsmodeller.

Impact of hygiene training on dairy cows in northeast India : en hygientränings påverkan på mjölkkor i nordöstra Indien

Mastitis in dairy cows is an emerging and challenging disease in the tropics, including India. Nation-wide reports suggest that the incidence of clinical mastitis varies from 3.94% to 23.25%, and for subclinical mastitis from 15.78% to 81.60%. In Assam, a northeastern province of India, dairy is an essential part of the mixed farming system that exists in the state, but the milk yield is far below domestic standards. In 2009-2010, International Livestock Research Institute (ILRI) and local associates started to develop a training program for local farmers in Assam, in order to enhance the informal bovine dairy sector in and around Guwahati, India. The project continued until mid-2013.

Optimering av B-stolpe

Two elementary schools are now being built in Gråbo (in the municipality of Lerum),Röselidsskolan and Ljungviksskolan, which are both designed with solar thermalcollectors for the schools domestic water heating. During the summer while thelargest amount of solar heat can be generated, the activity hence the domestic wateruse in the schools are heavily reduced. Both schools are connected to the local districtheating system which makes it possible to use the solar collectors to deliver heat tothe district heating.The purpose of this thesis is to evaluate the two systems mentioned above and todetermine which system is more suitable to apply on a school. The building whichconditions were used for this evaluation is Röselidsskolan.A solar heating plant of each system type was dimensioned from the expected andknown conditions of the building. The purpose with the dimensioning was to makethe solar plants replace the ordinary energy source as much as possible.

Sheep enterprise budgets : beneficial planning tools within Agriwise Macedonia

Generally in Macedonia keeping farm records and farm business planning is not often practiced like an ordinary activity in farming. Therefore one of the crucial things to do it is to comprise and continuously practice record keeping of farm data. The efficient and justified farm business planning should be based on farm records about the previous work of the farm, which will bring a structured approach for planning all the activities, as well as provide a good basis for attracting investors and creditors for the additional expansion of the business.Given that sheep breeding holds an important part of the livestock production in Macedonia, there is a need for adding analytical sheep enterprise budgets to support the farm business planning process at sheep farms.The aim of this research was to develop sheep enterprise budgets created on the best production practice for Macedonian conditions of breeding and test their applicability into the farm business plan model Agriwise Macedonia. The sheep budgets were composed with a process of data collecting consisted of direct farm data (for the cases), expert's consultation and relevant desk research, as well as a literature study. The aim of doing it was to attain more accurate calculations of the enterprise budgets, which will result in a more precise outcome in the farm business plan model Agriwise Macedonia.

Dagvatten i Märsta : förslag till anläggning för ekologisk hantering samt metodöversikt

Stormwater in urban areas has been treated as a problem for a long time. The large proportion of impermeable surfaces inhibits the water from infiltrating in the ground to the same extent that it does in nature. This causes intensive surface flow during rain, which in turn causes inconveniences such as decreased accessability, floods and increased risk of desease spreading. Drainage through pipes is the traditional and usually functional metod for storm water disposal. That is as long as water flows are moderate. But precipitation varies naturally in amount and intensity and additional impermeable surfaces make some pipes insufficient for heavy or lasting precipitation.
