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.

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.

Effekter av landskapets sammansättning på humlearters förekomst

The species in the genus bumblebees (Bombus) are important pollinators. In the world there are 250 bumblebee species and there are 34 species in Norway. The purpose of this study is 1) to assess changes in the species composition of bumblebees in twenty different places in Norway that have been inventoried first one time between 1939-1960 and the second time in 2012, and 2) to relate species richness and distributions to current landscape composition with the aid of orthophotos. In this study, I have used regression analyzes on the different bumblebee species that were present or absent at the inventory, using the premises of the following variables: low or high altitude, latitude, longitude and seven different types of land use (farmland, building/plots, open land/pasture, forest, wetland and open or snow-covered ground above the tree line) to see if there was any relationship between each species and the different variables. I have not analyzed what the landscape looked like at the first inventories and therefore we cannot say whether it has changed and if that is why species number has decreased. This would be interesting to study further and to see if there is any relationship between landscape changes and bumblebee?s species decline.

The importance of shade for dairy cattle in Sweden.

Today, there are no regulations saying that cows must have access to some kind of shelter at pasture during the summer. In more tropical countries, it is well-known that dairy cows might suffer from heat stress when exposed to sun and high temperatures. The well-being of the cows is thereby reduced and the production may also decrease. In Sweden, no research has been done in the area and therefore it is now a clear need of improved knowledge.The purpose of this study was to investigate the importance of shade for dairy cows in Sweden. The behaviour of 30 cows was examined to see any differences between cows with access to shade and cows without access to shade.

Hur ofta hälsar du på din granne? : En kvantitativ studie av integration som förklaringskraft beträffande befolkningssammansättning och radikala högerpopulistiska åsikter

A logical cause of migration is of course immigrants which is a topic always creating discussions. When arriving in a new country a process of integration with the goal to adapt to the environment is started. This study will explore the need for integration and seeks to examine the connection between population composition and radical right opinions.To fulfill the aim, a multivariate regression analysis is done on aggregated level in Sweden with statistics concerning the year of 2010. The relation between ethnic composition and voters support for the Swedish radical right party Sverigedemokraterna is studied as well as integration as an explanatory intermediate factor operationalized through unemployment, financial assistance and trust.The results of the study indicate a positive connection between immigrants from EU/EFTA and the voter support for Sverigedemokraterna. A negative relation is identified between trust and the voter support for Sverigedemokraterna.

Vitpunktsförskjutningens påverkan på ICC-profiler vid användande av optiska vitmedel

The connection between fluorescence and color management still is a relatively unexplored area. Thefollowing composition analyses the theory that when printing on fluorescent ink jet paper using ICCprofilesa more yellow print will appear. In theory the ICC-profile compensate for blue light that fluorescefrom the paper with the complementary color, yellow. The human eye apprehands this fluorescentlight as white.When categorizing a number of ink jet qualities some tests to indicate change of color in the final printwere made. Five qualities were chosen for further analyses, each with different white point.

Hur påverkas kolesterolvärden hos postmenopausala kvinnor med hyperkolesterolemi vid intag av isoflavonoider?

Sahlgrenska Academy at University of GothenburgDepartment of Internal Medicine and Clinical Nutrition3AbstractTitle: How does isoflavones in combination with soy protein impact cholesterol levels in hypercholesterolemic postmenopausal women relative to milk protein?Author: Emma Edberg och Emma NilssonSupervisor: Lena HulthénExaminer: Anna WinkvistProgramme: Dietician stydy programme,180/240 hpType of paper: Examination paper, 15 hpDate: 2014-05-26Background: Hypercholesterolemia is a major risk factor for cardiovascular disease and the number one cause of death among women in Western countries. Declining levels of estrogen at menopause could be a contribution factor. Isoflavones is a vegetable substance, with structural and functional similarities to the human estrogen. This is a potential reason for possible cholesterol-lowering effects.

Free cow traffic in automatic milking systems (AMS) : a case study on nine commercial dairy farms in Sweden

In Automatic Milking Systems (AMS), cows are kept in a free stall barn equipped with one or several milking units (MU). The cows? activities in the system are called cow traffic. There are three types of cow traffic systems: guided, partly-guided and free. Free systems have no gates, allowing the cows access to the feeding and resting areas at any time.

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.

En studie kring välfärdsindikatorer i mjölkproduktionen : förslag till hur Sigill Kvalitetssystem AB kan arbeta för en god djurvälfärd på certifierade gårdar

In this final thesis a study about welfare indicators in the Swedish milk production has been carried out. The system Swedish Animal Welfare Monitoring Scheme developed by the Swedish Dairy Association has been used as a base and the EU project WELFARE QUALITY® has also been used as a source of information. Focus groups have been used as a qualitative investigating method. This included four focus groups, two with farm auditors from the two different dairies and two with dairy farmers. This method was chosen because in this way one can study how a conversation about a given subject takes form in a respectable way.

Policies affecting the competitiveness of dairy production in Sweden, Denmark and Germany

Denmark, Germany and Sweden are along with 24 other countries members of the European Union. Being part of the European Union also means being part of a European market. Within the union barriers for trade has been abolished in order to create more open market. This open market has also contributed towards a more globalized market for dairy products. What used to be a domestic market has become globalised with increasing trade among the members.
