Berthåga kyrkogård

The aim with the literature study is to inform about the risks that exists in large dairy farms(with focus on mastitis and hoof health) and to inform about the milk industry in Sweden.Personal comments from two study visits (Nötcenter Viken and Vadsbo Mjölk AB) arelinked together with the literature and forms into a discussion regarding sustainableagriculture versus the milk cow's welfare.The profitability for Sweden's milk farmers have decreased because of the decreased milkprice and current inflation. This leads to an increase in herdsize in order to make a profit.The milk cow herds in Sweden becomes fewer year by year and the herdsize increases. Theincreased herdsize can cause a decrease in the time the farmer spends per animal. This canaffect early disease detection and prolong the animals suffering.Swedish Board of Agriculture published (2008) statistics showing that today's milk cow ismedicated primarily because of two reasons; mastitis or hoof problems. Mastitis is thereason to two thirds of all treatments that are carried out.

The use of artificial insemination in dairy farms in urban/peri-urban Kampala, Uganda : a study of knowledge, attitude and practices

Uganda is one country with fastest growing populations in the world and with more than 25% of the population living in poverty. There is a rapid rural urban migration with increasing demands for food for low income earners especially in these areas. One way to mitigate food insecurity is to increase milk and meat production efficiency, and thus reproductive performance of cows is crucial for good production. A well-documented strategy for improving dairy cow productivity through faster genetic improvement is to breed dairy cows using proven semen via artificial insemination (AI). AI has been used in Uganda for over 60 years but only less than 10 %, a small population of the country?s herd has been bred that way. The aims were to study knowledge, attitude and practices factors influencing cow fertility results on dairy farms around Kampala using AI and to propose ways of promoting increased use of AI in Uganda.

Latent värmelagring i vattenburet uppvärmningssystem med elpanna för byggnadsapplikationer

Latent heat storage is a way to store thermal energy when a phase change material undergoes a phase change. The advantage of latent heat storage is the capability to store more energy per mass unit than other heat storage methods. The most commonly used phase change in latent heat storage is the transition between solid and liquid. Phase change materials can be divided into organics, inorganics and eutectics.In the Nordic electricity market the price of electricity is set every hour by Nordpool spot, which leads to price fluctuations because of changes in demand. The main goal of this report is to create a latent heat storage system in a single-family home and investigate the possibility to save money by charging the latent heat storage system when the price of electricity is low, and discharge when the price is high.The thermodynamic model consisted of a ?tube-in-tube? heat exchanger with phase change material in the outer tube and water as the heat transfer fluid in the inner tube.

Klamydiainfektioner i Sverige  : Kan en geografisk analys förklara det rumsliga mönstret?

Chlamydia is a sexually transmitted infection. The infection rates have increased in the last decade. During 2008 the trend rates declined in all counties and regions in Sweden. Chlamydia infections have a geographical spatial pattern differences. This is seen from the national surveillance data report from the Swedish Institute for infectious disease control (SMI).

Riktad avmaskning mot spolmask på föl

Infection with Parascaris equorum is common among young horses in Sweden as well as in the rest of the world. The parasite has a direct lifecycle and reproduces in the small intestine. The eggs are passed out with faeces and become infective after approximately two weeks. The horses get infected when they ingest eggs that are dispersed in the environment. The symptoms seen in horses usually include retarded growth and loss of weight.

Svensk tjänstehundsavel : en återblick och nutidsbeskrivning samt förslag inför framtiden

In 1936 a governmental breeding project was started with aim on military use. The police later came to use dogs from this project as well. In order to utilize dogs that could fit for other purposes training and education of dogs for search of different substances and of guide dogs for blind persons was performed. A political decision to privatize the whole dog programme was taken in 1992. During most part of the time one had serious economical issues since too few of the dogs that were bred could be considered to fulfil the basic demands for service. To satisfy the need of service dogs private bred dogs were bought as well.

Leaf structure and localization of a transgene protein in barley

Barley is one of the most important cereals cultivated in the Nordic countries. Climate change brings warmer and moisture climate which favors fungal diseases. In the cropland barley can be seriously infested with hard fungus attack. Since it is important that the yield bears a high quality it is of great importance to find varieties more resistant to attacks.Pathogenesis-related (PR) proteins are stress proteins induced in the plant in response to infection and abiotic stress (van Loon, 1997). PRs are shown to have antimicrobial activity differing between bacteria, fungi and oomycetes (Tandrup Poulsen, 2001).

Echinococcus multilocularis in wild boar : aiming at an alternative surveillance method

This study was the first part of a larger project investigating a new surveillance method for Echinococcus multilocularis. In this study we examined livers from wild boar (Sus scrofa), looking for lesions caused by E. multilocularis. E. multilocularis is a small tapeworm which has an indirect life cycle.

Brunstvisningsförmåga hos SRB- och Holsteinkvigor

Oestrus in dairy cattle has changed over the last decades, the duration has decreased and the intensity of oestrus has declined. A possible explanation can be their high and increasing milk production. Heifers ability to show oestrus is probably not affected to the same extent. The aim of this study was to estimate and compare oestrus duration and strength in heifers of the Swedish Red and Holstein breeds. Standing oestrus has been the primary oestrus sign during many years.

Potentiella virala zoonoser hos apor på svenska djurparker år 2008

This paper is a compilation of some of the important viral zoonosis that can be passed from apes and simians (simian and prosimian) to man. Viral zoonoses are viral diseases that can be passed from animals to humans. The paper will also provide a better insight of the risks workers and visitors to the zoo can be exposed to. The viruses that this paper is focused on is herpes Bvirus, simian T-lymphotropic virus type 1 (STLV), simian immunodeficiency virus (SIV), Ebola virus, Marburg virus, yellowfever virus, monkeypoxvirus and hepatitis B virus. The choice of viruses is based on how infectious they are and how pathogenic they are.

Privilegierad mobilitet? : Flygplatser, resande och säkerhet

Never before have so many moved so frequently as now. Mobility lies at the centre for the concern ofstates, business and technological development. Some even claim that we are witnessing a mobility turn inthe social sciences. However, as the capacity to move has increased so too has the control and surveillanceof mobility become more extensive. Since September 11, 2001 security has been the defining paradigm fora variety for actors.

Kan hamlingen fortleva som tradition? : en studie över hamlingens historia och framtid i Bråbygden med omnejd

Hamling och andra former av lövtäkt för utfodring av tamboskap, var tidigare mycket vanligt men har minskat betydligt fram till våra dagar. Arter, som under åtminstone ett par tusen år anpassat sig till ett liv i, eller i anslutning till de hamlade träden, hotas idag av utrotning. För att kunna säkerställa fortlevnaden för dessa arter samt för de hamlade träden och hamlingen som tradition, krävs kunskap, dels om hamlingsförfarandet i äldre tider, dels om förekomsten av hamlade träd i dagens landskap. Genom att samla in och datera grenprover, kartlade jag i detta arbete senaste hamlingstidpunkt i Bråbygden, i Oskarshamns kommun. För att bedöma hamlingens utförande och potentialen för ytterligare hamling i området, studerade jag också förekomsten av döda träd med hamlingsspår, grova (brösthöjdsdiameter över 30 cm) askar, lindar och lönnar utan hamlingsspår, samt tillgången på tänkbara nya hamlingsträd. En enkät ställd till markägarna i området samt en omfattande litteraturstudie över hamlingens praktik och historia i Sverige ingick också i studien. På de 72 fastigheter som besöktes, tog jag prover från 406 träd.
