Kaninen som produktionsdjur
The purpose of this report was to obtain an overview of rabbit meat production in the world, in terms of breeding and feeding. It examines how different feed components contribute to the health of the rabbit as well as the quality of the carcass, and the breeding strategies that are most common in the major producing countries. The production of rabbit meat in Sweden is at present not very large, but it is gaining ground, and that is why this paper mainly deals with the rabbit production abroad. This report also examines the disease Rabbit Viral Haermorrhagic Disease (RVHD) in Sweden, where this disease can cause big problems.
The rabbit (Oryctolagus cuniculus) is very special, both in its reproduction and digestion. There is no specific mating season and the digestive tract is designed to digest forage efficiently.
Utveckling av programvara till ett inbyggt styrsystem
This thesis considers the development of the software for an, newly developed, embedded real-time control system, based on a Periferal Interface Controller (PIC). The control system is developed to be used for several different applications. In this thesis work, software for two different applications are developed. The first task is a time controlled system, while the other task is implementation of aPI-/PID-controller. A user interface is also developed and implemented.The time controlled system is an automatic horse feeder, which is used for feeding horses at certain predefined points in time.
Valsningsteknik för extremt höghållfasta tunna stål
New high strength steels require improved cold rolling techniques. The aim of this degree project was to develop a new and money saving cold rolling technique to manufacture steel strip for saw blades. The work is based on earlier rolling experiments made with a high carbon steel grade at LuCoil Steel AB. The work also focused on the mill requirements to cold roll high strength steels. The results show that LuCoil?s existing cold rolling mill was actually designed for rolling low carbon steel.
Beskrivning av systemfunktioner i kärnkraftverk med hjälp av objektorienterat modelleringsverktyg
In order to facilitate design and maintenance of such a large and complex site as a nuclear power plant, all system functions must be described in a stringent way. In the past, these descriptions consisted of text documents and logical diagrams, but today there are an increasing number of object-oriented programs available on the market which might be used for this purpose. This Master Thesis has made a closer study of one of these programs named Rational Rose. The principal of the program is to facilitate software design and development, not to create models of plants. However, using the program the same way as developing software, specifying actors then gradually extend the model with use cases, use cases diagrams etc, the same methods can be used when modelling plants.
Antal liggbås per mjölkningsrobot i olika system för kotrafik : vilket är det mest gynnsamma antalet liggbås och kor per robot?
Detta examensarbete är en undersökning av hur många liggbås som finns i olika skötselsystem för robotmjölkning med dels fri kotrafik och dels olika former av styrd kotrafik.
Undersökningen föreslogs av Växa Sverige och är en enkät som skickades ut till 70 lantbrukare. Användbara svar till undersökningen lämnades av 44 av lantbrukare. I
undersökningen har vi valt att redovisa resultaten i 5 olika kategorier, Milk first, Feed first,
Frigående kotrafik, Flerboxsystem och Ekologiska.
Det finns idag inga rekommendationer för antalet liggbås per mjölkningsrobot baserade på praktisk erfarenhet, för lantbrukare som ska bygga nytt stall. De enda riktlinjer som finns är robotföretagens teorier och Sveriges djurskyddlag som kräver minst ett liggbås per ko.
I studien framkom att det var en stor variation i antal liggbås per robot och även i önskade antalet liggbås per robot. Faktorer som påverkade antalet liggbås var kornas medelavkastning, aktuellt system för kotrafik och hur lantbrukarna vande in kvigorna och sinkor till roboten
innan kalvning.
Methane production from dairy cows : relations between enteric production and production from faeces and urine
Methane (CH4) is a greenhouse gas (GHG) that contributes to the global warming. One of the largest sources of methane is livestock, preferably ruminants which alone counted for 30% of the total agricultural anthropogenic methane emissions in the year of 2000. The reason to why ruminants are such large contributors of methane are that the gas is produced in the rumen by enteric formation and leaves the animals by belching, exhaling or by the excreta.Diets high in concentrates can result in a lower emission of methane. Also diets with a high content of starch, such as alfalfa-grass, have a methane-decreasing. It is profitable to reduce enteric methane formation since that form of methane is unavoidably lost.
Emotionellt socialt arbete : En studie av professionellas former för och hantering av känslor och upplevelser i arbetet med unga tjejer med självskadebeteende.
This study elucidates the feelings and the experiences by working with the complex of problems of self-injurious behaviour, of six professionals. The purpose with this study has been to examine the feelings and the experiences of the professionals, coming up when they meet and treat young girls with self-injurious behaviour. The empirical basis of this study is built on interviews of six female professionals, working in the County of Kalmar. The statements of the informants were analyzed out of Goffman?s Role Theory and the norm perspective on social behaviour.
Fallstudie av 10 skånska gårdar för en lönsam stutproduktion :
During the summer of 2005 a number of steer producers in Skåne, Sweden, found that their animals graded less favourable according to the EUROP carcass grading system when slaughtered, than ordinary. The aim with this project was to determine factors that affects the production result in steer production and to find the reason to the lower classification. The project was initiated by Anita Persson, LRF, Skåne and was preformed with supervision from Ingemar Olsson, SLU, and Jens Fjelkner, Skånesemin. Ten producers of dairy steers located in Skåne was chosen for this study. The producers were interviewed to collect information about their steer production with respect to their planning and results.
Minskande andelar kraftfoder i foderstaten under betesperioden : effekt på mjölkavkastning och betesbeteende hos mjölkkor
Feed costs constitute a large part of the expenses of dairy farmers. Pasture is a high quality feed with a low cost. However, feeding with concentrates has been shown to enhance milk yield (Leaver, 1985; Bargo et al., 2003; Stockdale, 2004). The purpose with this study was to investigate how milk yield and milk composition were affected as the concentrate proportion in the diet decreased. Pasture behaviour was examined to see if the different concentrate levels affected the time cows spent grazing and ruminating.
Det Duala Ledarskapet - den heteronormativa strukturens upplösning
The purpose of this investigation is to reveal those hidden factors, which influence how leadership is practised, as well as the roles male and female play in their professions. Furthermore this investigation aims to elude the expectations and demands that leaders experience and their origin.The investigation is based on six interviews of senior managers, two male and four female. A qualitative approach has been utilized to penetrate the subject and understanding of the identified phenomenon. The theories employed to analyse the finding are Lincoln, Gerth & Mills and Merton. To further highlight certain specific results parts of Ahrne, Beck & Beck-Gernsheim theories have also been empoyeed.
Vad det nu hette...Jämställdhet...? : Ett utredningsarbete på en klinik
The aim of this investigation work " What was it called...Equality...? is to study a clinics current gender equailty plan from a gender approach and by a field survey see if, and in that case, how it can be improved. A connection between existing gender norms and gender power strukctures is applied in the results of this survey in order to illustrate their significance from an individual as well as a structural perspektive.The survey has been carried through by a field survey as well as a discourse analysis as method. Yvonne Hirdmans gender power system is on of the main theoretical points of departure.The results that I have achieved in this essay is that gender can be looked at in different ways within the labour market where women have the main responsibility over the family and are considered more nursing then men. Men on the other hand are thinking of their carriers and have higher salary requirements.
Att effektivisera ett förvaltarbolag
Executive SummaryThis final thesis has examined the effects of an increased centralization and better coordination of the distribution logistics at ABB in Västerås. The company is today strongly decentralized and there is a minimum of collaboration between the 20 business units. This is why the questions were raised; how could the business units coordinate outbound logistic activities and what effects would that provide. The objective of this final thesis is to provide basic data for a future decision-making which describe these effects.The report has mapped out the factors that are important to ABB in an evaluation of their logistic activities and how the outbound logistics work today. The four factors are cost efficiency, delivery service, environmental impact and logistics capability.
Selenium in Swedish sheep production
Selenium (Se) is an essential trace element that is involved in several physiological functions in mammals. Mostly, Se is bound to proteins, many of them with enzymatic functions. A group of seleno-depending enzymes, glutathione peroxidases (GSH-Px?s), are important as antioxidants and protects against free radicals. The activity of GSH-Px is strongly regulated by Se storage in the liver.
Ekologisk slaktgrisproduktion i Sverige :
This literature review describes organic pig production in Sweden, its advantages and disadvantages, but also how its problems can be reduced or solved. Organic pigs have the possibility to a more natural behaviour than conventional pigs. With outdoor pigs comes problems, especially during wintertime, concerning water and feed supply, thermal environment and supervision. Parasites and leakage of plant nutrients are other difficulties that comes with outdoor pigs. All problems and difficulties can be reduced or put right through correct management.
Effects of palmitic and stearic acids supplementation on milk yield, composition and milk lipolysis in dairy cows
When facing the fact that high yielding dairy cows has an increasing energy requirements, the practice of adding lipid supplements such as concentrates rich in palm oil and/or palm oil industry by-products become more common. Palm oil containing high levels of C16:0 causes high levels of free fatty acids (FFA) which are linked to larger milk fat globules (MFG) which affect the reaction of lipolysis resulting in rancid flavour and processing problems. Instead of using palm oil, rapeseed oil rich in C18:1 C18:2 can be used. In order to evaluate the effect of
added C18:0 and C16:0 on milk lipolysis, 30 Swedish Red lactating dairy cows including 15 multiparous (MP) and 15 primiparous (PP) cows were randomly divided in three groups
resulting in 3 10 cow-groups (5 PP and 5 MP cows per group) and fed one out of three concentrate mixtures: control (C), a standard concentrate mixture with no fat added; palmitate
(P) as C plus the addition of palmitate methyl ester (10 % in DM basis); and stearate (St) as C plus the addition of stearate methyl ester (10 % in DM basis). Milk yield was registered, and milk samples were collected and analysed for milk composition, FFA content and size of MFG.
