Kan ät- och liggbås påverka kornas välbefinnande?
The purpose of this literature review was from dairy cows? behaviour and welfare point ofview describe how feed bunk and cubicles in a loose house system should be designed. Todaydairy cows in Sweden and in the world have high demands because of a high milk production,stress and higher risk of being afflicted with diseases. Through selection in breeding the bestquality can be performed, but high demands of the environment for the dairy cow is above allalso important for a good welfare and for a good milk production. Feed bunks and cubiclesare just some parts to be designed in the best way for a good animal welfare.
Are changes in heart rate and/or arborisation of vaginal mucus useful parameters for detecting heat in heifers? :
The milk production per cow has increased considerably during the last 50 years and due to the breeding for higher milk production also brings decreased reproduction efficiency. In a Swedish study 1996 it was shown that on average only half of all estruses were detected. Every time a farmer fails to detect oestrus it costs the farmer about 1200 Swedish crones and the need of means of detecting oestrus is therofore large. With this study we wanted to investigate if heart rate respectively crystallisation of vaginal mucus (arborisation) could be useful means of detecting oestrus. We monitored two oestrus cycles in four heifers.
Effekter av två olika hösilagefoderstater på tarmfloran och träcksammansättningen hos häst och gris :
The aim of this study was to investigate if the botanical composition of haylage affects pH, dry matter content and microbial composition of the faeces in horse and pig and ileal environment in pigs. Two separate studies were conducted where pigs and horses were fed two diets containing haylages with different botanical composition. The first haylage was from a tilled land dominated by timothy and meadow fescue and the other haylage came from a meadowland with a large inclusion of dandelion, 25 % and common couch. The dry matter content (70.8 % and 73.0 % respectively) and the pH-value (5.7) were similar in both feeds.
The first study was made as a three-periods switch-back study with 7 Standardbred horses. In the first and the third period, 7 and 9 days long respectively, the diet consisted of the haylage from the tilled land, oats, sugar beet pulp, soy bean oil meal, lucerne pellets and brewers yeast.
En jämförande studie av kalvuppfödningen på KRAV-anslutna och konventionella mjölkgårdar :
In order to investigate if the KRAV-regulations have any effects on the health and welfare of calves, KRAV-affiliated farms were compared to conventional farms with respect to calf management and outcome. The dairy calf has had a low economical impact during history. Even today the value of the calf is low and a lot of calves have a poor health status. The calf breeding is built on tradition and on the fact, that cheap antibiotics have made it possible to ignore, the recommendations about good hygiene in the calf?s environment.
Hygienisering av torkat bioavfall
The main project Dry preservation of food waste from households includes a new technique concerning drying and storage of dried biowaste as well as a study of the sorting of household waste and further usage of the dried biowaste. A question asked in the project is, can the dried biowaste be used as a soil amendment? If organic waste is used as a soil amendment, precaution concerning hygienic safety risks has to be accounted for. The objective of this M. Sc.
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).
Vad ska man mäta för att veta? ? en studie av resursfördelningen inom Stockholms stadsbibliotek
The purpose of this master?s thesis is to study resource allocation among district libraries within Stockholm?s City Library (SSB) on three different occasions ? 1996, 2001 and 2005 ? and to examine whether there exist any inconsistency between the state of the allocation of resources and what might be considered reasonable. During the course of the study, it became apparent that some measurements are more relevant than others when determining whether the allocation of resources is reasonably fair. The most relevant ratio is the share of net cost per capita in relation to population and the population?s composition of children, youngsters and persons with foreign background as a result of relevant political governing documents giving priority to these three groups.
Styrelsesammansättning och styrelsens funktion i sociala företag
This paper is about the composition and function of boards of social enterprises. A social enterprise can be defined as a company, which is founded by users or external stakeholder in order to create jobs (or a work place), a meaning in live or to further integration. One tries to achieve this goal by a business activity and/or subsidies and/or neighbourhood projects. The amount of social enterprises grew steadily after the restructuring of social welfare in Sweden since the 1980. Alternative forms of welfare ? such as a social enterprise ? will probably grow further in importance.
Valberedning och tillsättning av styrelse enligt Svensk kod för bolagsstyrning: En studie av könsfördelning ur ett institutionellt perspektiv
Since July 2005 the major companies listed on the Swedish stock exchanges are required to apply the Swedish Code of Corporate Governance. The code states that companies shall have a nomination committee responsible for nominating new board candidates and seek to obtain gender equality in the Board of Directors. This paper examines the trend of board as well as nomination committee composition among Sweden's 60 largest publicly traded companies between 2005 and 2008. Our overall finding is that neither the board nor the nomination committee composition has changed to a notable extent during the period and that the share of newly appointed female board members has actually decreased. However, the trends vary between different sectors.
Bioactive peptides in long-time ripened open texture semi-hard cheese
Bovine milk is an excellent source of bioactive peptides. The bioactive peptides are in an inactive state in the protein and are released during enzymatic activity, e.g. during cheese ripening. Specific properties of bioactive peptides from ripened cheese has been reported, e.g. antihypertensive, antioxidative, antimicrobial, immunomodulatory and mineral binding.

Hackelselängdens betydelse för tuggtid och foderkonsumtion hos mjölkkor :
Today, our cows experience a harder pressure to achieve higher milk yield. To manage this challenge the animal needs first class feeding and treatment. An important aspect of the feeding is to fulfil the need from the cows of especially fiber; and fiber with a sufficient proportion of long particles. Both too much and too little fiber is bad for the wellbeing of the cow, and she might get diseases like acidosis.
Many models for feed management have been developed to secure that the animal gets enough of e.g. fiber with a sufficient proportion of long particles.
Kemisk karaktärisering samt nedbrytning av process- och avloppsvatten vid SCA Ortvikens pappersbruk
During pulp and papermaking process a huge amount of water is used. The wastewater contains a large amount of pollutants and has to be treated before it reaches the recipient. In March 2004 a new bleaching plant was started up at SCA Graphic Sundsvall AB, Ortviken?s paper mill using peroxide. The production of bleached thermo mechanical pulp and thus the load to the wastewater plant increased.
Magnesium chloride in dry cow silage to prevent hypocalcaemia
Milk fever, or parturient paresis, is the second most common disease in Swedish dairy cows. The disorder is associated with the onset of lactation when some cows are unable to meet the metabolic demands of calcium to support milk production and therefore develop a state of hypocalcaemia. Clinical hypocalcaemia (milk fever) may lead to coma and death in severe cases but subclinical hypocalcaemia has also been shown to have negative effects on e.g. feed intake and production and to increase the susceptibility of the cow to develop secondary diseases. The nutritional strategy applied precalving is of great importance in preventing milk fever and e.g.
Från digitalt till analogt : En kvalitativ studie av överföringsprocesserna från MIDI till notskrift i symfonisk musik
This study examines how to translate digitally composed symphonic music to note script and how it gets readable and playable. With the help of professional musicians from the Norrköping Symphony Orchestra, teachers from Kulturskolan in Norrköping as well as other musicians, I have learned how I can improve each individual stem in my composition. I also learned how to write for a real musician. My score have been analyzed by composers and a conductor which have given me a more in depth insight into composing symphonic music.The theory section describes important MIDI aspects, score preparation and note editing techniques. Thereafter is a section about the symphony orchestra and its instruments? history and how the situation is today.
