Hur en övergång till ett automatiskt mjölkningssystem påverkar juverhälsan :

Automatic milking systems (AMS) have been in commercial use since 1992 and have since 1998 increased a lot. The objective of this study has been to examine the development of udder health on farms converting to AMS. The study also included a comparison of how udder health developed depending on how farms handled cows with mastitis. This was because farms choose to either milk cows with mastitis in a separate barn or in the milking robot. Other studies on udder health on commercial farms have shown that somatic cell count increases both among individual cows and in the bulk milk when converting to an AMS. No differences between before and after converting to AMS in the proportion of cows treated for mastitis can be found in the literature.

Tidsåtgång i system med självgående/självlastande fullfoderblandare :

In this study I have compared two systems of handling TMR, self-propelled/ self loading mixers and conventional towed mixers, what has been investigated is the time for filling, mixing and feeding TMR as well as maintenance and fuel consumption. The background of this study is the structural rationalization within the Swedish milk production that has put focus on efficiency and reducing of costs. Forage and labour are the two biggest costs in milk production today. The study has been performed by visiting three farms and with a stopwatch measured the times for filling, mixing and feeding TMR. At the time for the visits, the users have been interviewed regarding maintenance and fuel consumption. They have also had an opportunity to give comments of how they experience the mixers. The result of the study after processing is that the average stock in the study can save 74000 SEK a year by reducing time for filling, mixing and feeding TMR to cows with a self propelled/ self loading mixer . The conclusion I can make of this study is that it?s not the size of the stock that decides whether it?s interesting to invest in a self propelled/ self loading mixer, but the presumptions on the farms, for instance forage logistics and mechanical equipment..

Utrikespolitik och krig : En fallstudie om USA:s invasion av Irak utifrån neoklassisk realism

In this essay i argue that there are three different variables that may be able to control the outcome of certain foreign policy choices. These three variables are External Threats, government division and public opinion. The Essay also tries to identify former president Bush motives behind the 2003 Iraqi War. It is partly argued that the three variables had a certain amount of influence on Bush decision making process. But the main focus lies on the motives behind the attack.

Bärbar - ett hållbart tygkassekoncept

Portable is a project with its starting point in plastic bags, how they negatively affect our planet and how people´s patterns of behavior and qualities of life are affected when people try to live more envi¬ronmentally friendly. Now we have reached the point when peoples way of living and consuming in the western world has to change. This is nothing new and we can now see that sustainability is start¬ing to get attention in every area.Today plastic bags are used on average for 12 minutes. Only one out of 200 is reused, and then only once . This is not sustainable at all.

Fodersammansättningens betydelse för tillväxt hos häst :

The aim of the present study was to investigate the effect on growth of foals on two different diets, either a forage-based diet or a diet containing approx. 40 % concentrate. The report also includes a review of the pertinent literature on the effects of diet on mares? milk and growth of horses. The hypothesis of the study was that a forage based diet will result in a similar growth pattern as a diet including more concentrates if the diets contain the same amount of energy, crude protein, lysine, calcium and phosphorous.

Syntes av hydroxyapatit/ nanocellulosa kompositer

Cellulose nanocrystals (CNC) are great candidates for composite materials. The reasons why CNCs are such attractive materials for them are due to their great mechanical properties, high aspect ratio and low density. On the other hand, hydroxyapatite (HAp) is a kind of calcium phosphate and a main component of bones and teeth. The purpose of the present study is to make oriented nano-sized composites with CNC and HAp. Although some researchers carried out to make CNC composites with HAp for biomedical materials, nano-sized and oriented ones haven?t been achieved yet.

Effekter av högt kaliumintag på magnesiumbalansen hos mjölkkor :

Magnesium is one of the most important minerals in the body and it participates in many essential processes, such as energy metabolism and protein synthezis. Magnesium deficiency in cattle may occur when they are let out for pasture in the spring, and is associated with tetany, known as grass staggers. A high yielding dairy cow often loses more magnesium daily in the milk than she has available in the body, and magnesium thereby needs to be provided in the feed to prevent the cow from being affected by deficiency symptoms. The uptake of magnesium is mainly located to the rumen and is not regulated by hormones. The surplus is excreted in the urine by the kidneys.

Jordbruk och mjölkproduktion med kor i Etiopien :

Ethiopia is the country with most livestock per capita on the continent of Africa. There are 34.5 million cattle that are used for drought, meat- and milkproduction and 85% of the population rely on agriculture for their survival in some way. Milk is produced in four main systems, through pastoralism in the lowlands, in mixed crop-livestock systems in the highlands, in and near big cities with only one or two cows, and in intensive farming systems. There are 17 cattle breeds in Ethiopia and some of them are more suitable for milk production than others. Several environmental and economic problems arise from livestock holding in the country, for example overgrazing, low production due to feed shortage, low quality of the avaible feed and non-existing breeding programs.

Bystämman som en mötesplats för jordägarna : En lokalhistorisk undersökning om de gemensamma resurserna inom Benestad byalag åren 1886-1928

This study examines the organization of the village society in Benestad, in southern Sweden, during the period from 1886 to 1928. The study focuses on the commonly owned resources in the village and how the landowners there came together and shared the resources. By studying the records of the societies? meetings, and in particular the cases that concerns the common resources, a categorization has been done. The results of the study show that the landowners in Benestad shared pasture lands, milk carriage and other resources with one another. Overall, the village society had a strong organization with at least two yearly meetings about the commonly owned resources.

Bestämning av kroppssammansättning hos överviktiga och obesa ammande kvinnor. Validering av bioelektrisk impedans mot röntgenabsorption.

Introduction: Pregnancy, obesity, aging and certain diseases are examples of conditions thataffect the body, its constitution and composition. Simpler methods to estimate bodycomposition are needed to complement more advanced traditional methods to better identifythe health status without sacrificing accuracy and precision.Objective: To validate the results of body composition from bioelectrical impedancespectroscopy (BIS) against results from the study reference method, dual energy X-rayabsorption (DXA), in overweight and obese lactating women after childbirth.Method: The design of the LEVA-study (Lifestyle for Effective Weight loss during lactation)consisted both intervention and longitudinal follow-up, which gave the opportunity tovalidate the absolute values (accuracy) and the ability to detect changes (precision). Themean difference between methods was tested statistically by paired t-test. Bland-Altman plotsused to examine the degree of agreement between BIS and DXA, but also distribution andany systematic differences. Association between methods was measured by using Pearson´scorrelation coefficient.Results: Between BIS and DXA, absolute measurements of the variables fat-free mass (FFM)and fat mass (FM) showed a statistically significant difference (p < 0.001).

Storage stability in a milk based UHT-beverage : effect of pH, carrageenan and storage time

The different characteristics of many food products, such as aroma and texture, changes during storage time and become undesirable. The reason is instabilities within the product which become prominent as the product ages. These changes in characteristics are quality losses caused by changes in the product?s intrinsic and extrinsic environment. The stability in UHT-milk and beverages similar to it have been studied in the past decades and a certain focus have been on age gelation which is a common defect in these type of products.

Kreditgivning till lantbruksföretag : en jämförelse mellan Sverige och Danmark

In relation with structure transformation in farm companies with bigger animal population and pressure at the milk price, the farmers in both countries have to invest more money in the company to endure. This had conduct what more owners had seen grown requirements to invest in bigger population barns. The investment is necessary to retain stability in the economy for the companies, at that time when the profitability for small production barns decrease. This essay carries out through a case, there the activities main part are milk production. The present operation consists of 82 milk cows in long stall with a yield on 10 500 kg ECM. The idea is that the company should increase the activity to 180 cows.

Tonåriga pojkars självkänsla och kroppsmissnöje : Har massmedia, extraversion och BMI någon betydelse?

Tidigare forskning kring pojkars självkänsla och kroppsmissnöje i relation till massmedieanvändning, extraversion och BMI har utfallit något olika och är inte lika omfattande som forskningen kring flickor. Syftet med denna undersökning var att ta reda på om massmedia, extraversion och BMI har betydelse för tonåriga pojkars självkänsla och kroppsuppfattning. Kvantitativ metod i form av en enkätundersökning användes. Sjuttiotvå gymnasiestuderande pojkar besvarade enkäten som innehöll instrument för att mäta BMI, extraversion, kroppsmissnöje, massmedieanvändning och självkänsla. Resultatet visade att massmedieanvändning inte korrelerar med vare sig självkänsla eller kroppsmissnöje.

Rörelser i den mediala offentligheten - En studie av de nya sociala rörelsernas mediebild under protesterna i Göteborg juni 2001.

This thesis highlights the complex relationship between social movements and the mass media. The new social movements really have to struggle to get access to the media sphere, often enforced to use spectacular media strategies, and at the same time maintain their political messages. This struggle gives us reason to question the liberal notion of the media as a neutral arena for political communication and debate. In fact we argue that the media industry should be seen as a powerful actor and that the mass media serves to maintain and enforce an ideology that serves the political and economic elites in the liberal capitalist democracy. The Social movements that seek to question these elites and present an alternative, as they did during the EU-meeting in Gothenburg 2001, quite clearly gets far from neutral media image of the political actions taking place instead the are portrayed as violent or associated with violence and not presented as legitimate or believable political subjects..

Crowdsourcing för en ökad medborgardialog. En studie om en ökad medborgardialog för Västra Götalandsregionens kollektivtrafiknämnd

Today, companies can take advantage of mass intelligence by making use out ofcrowdsourcing. Crowdsourcing is a business model that uses the power of the collective bythe offer of a problem by means of competitions in various social media. The benefit ofcrowdsourcing is that the company gets more creative and creative solutions to the sameproblem, which would not have been possible if the company solved the problem internally.The larger mass gains an insight into the company, which in return also releases power tothe company's development. The study aims to examine the way in which citizens can beattracted to participate in the development of public transport using crowdsourcing. The studyis based on both qualitative and quantitative approach since the study has a qualitative pilotstudy.
