En pilotstudie av unghästars användning av ligghall i grupphållningssystem

Today, individual indoor stalls and individual outdoor paddocks are the most common way to house horses in Sweden. The way that we manage, house and feed the horses are not optimal for the species natural basic behavioural needs. However, the awareness of this grows in the context of research and the emergence of alternative housing systems. One of the alternatives to the traditional format in individual boxes is called group housing. Group housing systems allow horses to live in herds and they can choose how they want to distribute the hours of the day between movement, resting and foraging. The purpose of this study is to examine how frequently the young horses in a group housing system use the indoor lying area.

Green feed in the marine fish farming : how to communicate water benchmarks to stakeholders

Global catch fishery is said to been oppressed to its limit (Boyd & Schmittou, 1999), further implying aquaculture might be the only solution to the world demand for fishery products. The applied term aquaculture in this paper refers to the one used by NOAA (2008); breeding, rearing, and harvesting of plants and animals in all kind of water environments, including but not limited to ponds, rivers, lakes, and the ocean. According to Shamshak & Anderson (2008, p. 74) aquaculture has over the past 20 years been the fastest growing food sector with an average annual growth rate of 8.7%. It further represents approximately 37 % (Shamshak & Anderson, 2008, p.

Effekt av biotintillförsel på klövhälsan hos mjölkkor i lösdrift : ett kontrollerat fältförsök på tre gårdar

The Effects of dietary biotin supplementation on hoof health in Swedish dairy cows - a controlled cohort field study. The aim of the present degree project was to investigate the effects of biotin supplementation on hoof health in dairy cows. The experiment was performed as a controlled cohort study in three commercial farms in western Sweden from January 2002 to October 2002. The cows were all housed in cubicle systems with transponder concentrate feeding systems. Within each farm the cows were allocated to either biotin or control treatment. The biotin groups received 20 mg of biotin per cow and day, starting 14 days before expected calving.

En studie om konflikten mellan företags affärsstrategi och CSR-arbete i lågprishandeln

A wish for a higher standard of living has driven the rate of consumption in Sweden. Mainfocus in business is on a higher growth and profitability where some companies use a lowprice strategy to win competitive advantage. The positive consumption pattern spiral is oftendiscussed in media, while criticism is limited and often refers to the environment. In order toreduce our ecological footprint we should consume more sustainably. More and morecompanies implement CSR (Corporate Social Responsibility) in their business strategy tobecome more sustainable.

Plantetablering och tillväxt för sådd och planterad tall 2-5 år efter markberedning med harv eller Huminmix-teknik inom Holmen Skog distrikt Norsjö :

The objective of this work was to compare the environmentally gentle soil scarification technique Huminmix (with possibilities to do track-grinding/HMMspår, long-scraping/HMMlångfläck and mounding/HMMhög) with conventional disc trencher, concerning seedling establishment and growth of direct seeded and planted Scots pine seedlings. Inventories were made during June and July 2005, in 34 seeded and 6 planted stands from 2000 ? 2004 (1- 5 years old) of lichen- and myrtillus/vaccinum-type in Holmen Skog AB´s district Norsjö in Västerbotten. The Huminmix-technique had been used for HMMspår in the seeded stands and for HMMhög in the planted stands (HMMlångfläck has been used from the year 2006 for direct seeding). The studied stands had been seeded with the same amount of seeds according to stand data.

Development of new food products with components active against Helicobacter pylori - with purpose to improve gastric health in humans

Gastric and intestinal disorders are common and costly human health problems worldwide. Helicobacter pylori are a gram-negative, pathogen bacteria and the most common cause of duodenal and gastric ulcer in the stomach the intestinal mucosa. Prolonged infection and colonization can lead to chronic gastritis and stomach cancer. H. pylori are present in the gastric and intestinal mucosa of half of the world population and a relation between infection and low socioeconomic status has been shown.

Valutariskhantering vid exportaffärer : - en studie av stora svenska exportföretag

AbstractBusiness, or business decisions always involves an endangerment from the company?s aspect, but when it comes to business with foreign countries the risk profile looks quite different from the profile the company has when its doing business inside the country. Therefore, it is extremely important for an export company or import company to carefully consider the risks that are enclosed with the deal, before he makes the decision to enter a deal. One of the most important risks a company have to considerate when doing business with foreign countries is the currency risk. A company is exposed to currency risk when either long-term or short-term changes in the exchange rate may affect the result of the company, competitive position and growth.

Stereoskopisk 3D-film : En studie om tittarens upplevelse av 3D-film

Since the release of Avatar in 2009, the 3D movie industry has experienced an apparent growth. Almost all blockbuster movies are being released in 3D at the cinema, but the 3D format has been met with mixed opinions by the consumers. Some argue that 3D is the future, while others believe that the 2D format is enough for an appreciated movie experience. Through a qualitative survey, twenty participants with 3DTV in their homes answered questions regarding their experience of 3D movies and what improvements they desire. We suggest that 3D film creates immersion, realism and effects that 2D films can´t handle.

Site preparation, planting position and planting stock effects on long-term survival, growth and stem form properties of Pinus contorta on southern Iceland

In order to evaluate different afforestation methods for exposed heath lands a field experiment was established in Mosfell on southern Iceland in 1989. The trial comprised six different site preparation methods (control, herbicide application, tree shelters, patch scarification, TTS trenching and mounding). In total 960 container seedlings (1+0) and 960 Nisula roll transplants (2+1) of lodgepole pine were planted. Various planting positions (furrow, hinge, no site preparation (control) and on top of mounds) were tested within the site preparation treatments. This study involves renewed measurements and analyses of the trial.After 19 years the overall survival was 51,7 %.

Finns det risk för att Sverige går in i en ny fastighets- och bankkris?

The purpose of this thesis is to investigate if there is a risk that Sweden will go in to crises at the house market and in the bank sector. The Swedish house prices have in the last years growth very high and quickly and are now over the development in the beginning of 1990. The method I use to investigate this is a multiple regression model. I follow a regression that both OECD and the Swedish Riksbank use. The difference between my analyse and theirs is that we use different periods..

Immunokastrering av gris : för- och nackdelar ur produktionssynpunkt

Kastrering av smågris för att motverka galtlukt görs idag i Sverige under grisens första levnadsvecka utan bedövning. EU kommissionen har lagt fram ett förslag på att från och med 2012 ska all kastrering av grisar ske med bedövning, och kirurgisk kastrering ska upphöra från 2018 under förutsättning att vissa praktiska problem har lösts tills dess. Olika alternativ till dagens kastrering är således ett mycket aktuellt problem och ett av alternativen till detta är immunokastrering. Immunokastrering sker genom att man vaccinerar grisen mot ett endogent hormon, GnRH (gonadotropin releasing hormone), vilket hämnar testikelns funktion och minskar bildning av galtluktsämnena androstenon, skatol och indol. Denna litteraturstudie är inriktad på hur immunokastrering påverkar grisarna ur produktionssynpunkt med fokus på kött- och fetthalt, beteende, foderåtgång och andra problem som diskuteras kring den praktiska tillämpningen av immunokastrering på gris i Sverige. Studien visar att immunokastrerade grisar har högre kötthalt, lägre fetthalt och mindre foderåtgång än kirurgiskt kastrerade grisar.

How drinking behaviour in automatic milk feeders can be used as early disease detection

Healthy calves are the foundation in order to run a profitable diary production. Being healthy as calf results in a better start in life and good growth is expected to follow. Within dairy production it becomes more common to rear calves in groups and feed them by an automatic milk feeder. The milk feeder enables for the calves in greater extent to ingest milk or milk replacer several times per day and they are also able to perform natural behaviors in greater extent. Group rearing of calves puts higher demands on the animal keepers to localize individual calves in the group pen, showing signs of illness.

Nötköttsproduktion i Västerbotten

Beef production in Sweden has traditionally been about rearing of dairy calves to slaughter. With reduced number of dairy cows and accordingly less dairy calves for slaughter, there has been a need for new forms of beef production in Sweden. In Västerbotten there are good conditions for beef production with a high feeding level of roughage due to favourable climate. The aim of this thesis is to, through interviews with ten farmers with beef production in Västerbotten, study what and with how much they feed their animals and link the results to production level. The thesis begins with a literature review where the general feeding standards and feeding recommendations for beef cows and growing cattle are examined.

Kan D-vitamintillskott minska depressiva symtom?

Background: Sweden is a country where vitamin D deficiency seems to be common, partly because of its geographical position, which reduces the availability of UVB radiation, but also that people avoid sunlight due to increased skin cancer risk. Research shows that vitamin D plays an important role in the prevention of many diseases such as cancer as well as autoimmune and neuropsychiatric diseases.Vitamin D is a fat soluble pre-hormone and a collective name for closely related compounds which act as hormones after undergoing a transformation in the body.Humans can utilize vitamin D through diet and produce it in the body by exposing the skin to the sun. Previous observational studies and epidemiological studies have established a hypothesis that there seems to be an association between vitamin D supplementation and reduction of depressive symptoms.Objective: The aim of this study was to investigate if vitamin D supplements may decrease depressive symptoms.Methods: This work is organized as a literature review and article search is made in the database PubMed in January 2012. Keywords used were ?vitamin D and depression? and inclusion criteria were: randomized clinical trials, be conducted on humans, written in English.
