The aim of this literature review was to investigate whether the modern dairy cow has the time she needs to lie down and to sleep and what deprivation of these behaviors could lead to. Current research seems to agree on the fact that sleep is essential but there is no uniform explanation of the function of sleep, even though there are many theories. It is known that sleep has an important impact on the immune system and that sleep is increased in case of an infection. Sleep deprivation causes many negative effects including reduced function off the immune defense, increased metabolic activity, malnutrition and increased heart rate. It has also been found that deprivation of sleep could cause increased mortality.

The aim of this study was to compare activity, lying down and getting up behaviour, weight gain and cleanliness in heifers in cubicles versus on deep-litter. The study was conducted from autumn of 2005 until autumn of 2006 in a commercial organic dairy herd with 340 cows. In 2005 the farm rebuilt half of the young stock accommodation from deep-litter pens to cubicles. The experiment used 150 heifers of the breeds Swedish Red, Swedish Holstein and crossbreeds between these, all born on the farm. The animals were divided into three blocks based on breed and within each block they were sorted after increasing age. The youngest heifer in each block was randomly allocated to one of two groups, cubicle or deep-litter pen.

Med stöd av teorier om barn och kommunikation, mediepåverkan liksom synen på barn som publik ville vi i denna uppsats ta reda på hur barn i mellanstadiet i Halmstad läser filmen "Dylans historia?, en egenproducerad programserie om Halmstads historia.Frågeställningen var: Hur ser det narrativa mötet ut mellan producenternas intentioner, så som de uttrycks i produktionens/filmens narrativa element, och barnen. Det vill säga, hur uppfattar barnen filmen? Utifrån Stuart Halls teorier om ?encoding - decoding? jämförde vi producenternas intentioner med texten (filmen) med den tolkning som publiken (barnen) gjorde. 19 barn i åk 4 och åk 6 intervjuades.

If you keep cattle in a herd outside all year round on big varying grounds, their possibilityto perform their natural behaviour increases. This way of keeping cattle requires that youprovide them with their other needs, like shelter and a dry and clean resting place.According to the animal welfare authority´s regulations on livestock farming, only animalsthat are suited to stay outside during the cold season are allowed to be kept outside. Theyshould also have access to a shelter or another building that gives them protection from theweather and wind and provides a dry and clean resting place.Research has shown that as long as cattle do not get exposed to precipitation and wind theywill manage low temperature well. Some of the things that will affect how well the animalshandle different climates are the isolation ability of the fur, the animals´ body size and thefeed intake. A dry lying place that is both insulating and moisture absorbent is also of greatimportance.

Animals in zoos live in more barren environments than their conspecifics in nature. In nature, elephants spend more than 75 % of the day foraging and have been observed lying down two hours during night. Stereotypies are common in many different species in zoos. Stereotypic behaviors may constitute up to 50 % of the daily activity budget of zoo elephants. Modern zoos try to reduce stereotypic behaviors by means of environmental enrichment.

There is currently no activity or behavior meters validated for sows under Swedish conditions where the sows are loose-housed during farrowing and nursing. An activity meter could in particular be used to detect sows that are getting ready for farrowing. Assistive technology in order to register different behaviors would be extremely useful in research and breeding. In this study, a HOBO Pendant G data logger was validated for two different functions. First, the function as a pure activity meter in which the accelerometer's ability to detect an upcoming farrowing was evaluated, and second, the accelerometer's ability to distinguish between the behaviors standing up, sitting down, lying ventrally and lying laterally on the right and left sides was evaluated. The accelerometer was attached to a collar around the sow's neck, and was recording its location every two seconds for six hours a day for ten days on a total of twelve sows.

SUMMARY By altering the longitudinal slopes of the cubicle floors the drainage could be improved. If the altered slopes also position the cows further back in the cubicles the effect could be cleaner lying surfaces. In result this would lead to lower labour requirements, cleaner cows, cleaner udders and a minimization of the risks of mastitis. However, if the altered slopes lead to that the cows position themselves more diagonally in the cubicles the positive effects could be reduced. The altered slopes could even have a negative influence on the animals? natural lying behaviour.

Sleep is a vital part of life. Even so a lot of the mechanics regarding sleep is unknown. The dairy cattle of today live a stressful life, as their high milk yields forces them to eat large amounts of feed and spend a great portion of the day ruminating. Do they have time to get enough sleep? Which factors affecting the need of sleep in dairy cattle are largely un-known.

Peat litter is a soft material with high absorbency. About hundred years ago many farmers in Sweden used peat litter to their dairy cows. After the World War II the use of peat litter decreased and the farmers used more straw. Nowadays (year 2007), when it is harder to find straw and sawdust to buy, peat litter is advancing again. The purpose with this study is to investigate peat as a litter to dairy cows.

The wood-living beetle Ceruchus chrysomelinus is a rare species connected to natural forests. In Sweden, it is red-listed as endangered (EN) and an action plan for its preservation has been done by the Swedish Environmental Protection Agency. In this work I have therefore investigated how a translocation of the species succeeded after 17 years. I aimed to study the species dispersal biology, its substrate preferences and the supply of suitable wood on this site. The study was performed during 2012 in Pansaruddens nature reserve close to Uppsala in Sweden, which is a spruce dominated forest.

Cattle used for meat production can be held outside all year round and due to the legislation they should have access to shelters or other buildings for protection against the elements giving them a dry and clean bedding. There are different opinions concerning their need of protection and the question about necessity of shelters for cattle is of current interest due to a less profitable economy in meat production and the investment costs for shelters. The aim of this study was to acquire more knowledge about the natural behaviour of cattle concerning their use of shelters. The basis of the study was a series of questions regarding when animals choose to stay in shelters, if shelters were used less when they had access to protecting vegetation, how temperature and weather conditions affected the use of shelters and the influence of distance between shelter and feed. Behavioural studies was conducted at five different farms where six groups of suckler cows and heifers of following breeds and crossbreeds were observed; Aberdeen Angus, Charolais, Hereford, Scottish Highland Cattle, Simmental and the Swedish breeds SKB and SRB.

A common problem in forestry is plant death caused by frost. The risk of frost is highest on wind protected, flat or low-lying areas in the terrain. Here you often have regeneration problems with Norwegian spruce which is especially sensitive to spring frost. Swedish tree experiments have shown that the black spruce can be a suitable alternative on these areas, for example on moisture frost prone areas. The species originates from North America and its pioneer tree characteristics make it more frost hardy than Norwegian spruce.

The aim of this project was to quantify the total sleep time in modern dairy cows during24-hour periods and to investigate whether the total amount of sleep as well as timespent in different sleep stages varies between the dry period, early- and peak lactation.The distribution of sleep time between night and day was also examined. Furthermore,correlations between sleep and lying time, fluctuations in body temperature and heartbeat were included in the aim. Eight dairy cows of the Swedish Red breed were used inthis study, which was carried out between June and September 2010. In order toquantify sleep non-invasive electrophysiological recordings were performed.Simultaneously with collecting sleep data, body position and body temperature werealso recorded. No heart rate data was obtained due to difficulties of maintainingelectrodes for heart beat measurements attached to the skin.

Under sommaren och hösten 2009 fick Apolivas reklamfilm stor uppmärksamhet av såväl det svenska folket som i media. Uppståndelsen grundades i att en stor andel människor som tagit del av reklamen uppfattade den som skrämmande, medan Apolivas avsikt var att skildra de svenska, något melankoliska, väderförhållandena.Syftet med denna uppsats är att undersöka tolkningsskedet av Apolivas reklamfilm, hos flickor i nionde klass. Vår specifika frågeställning utvecklades till att ta reda på om den utvalda gruppen tolkar budskapet och känslan som förmedlas i reklamfilmen, på det sätt som Apoliva avsett, med utgångspunkt i Halls (2009) encoding/decoding-teori. Enligt denna modell finns tre olika sätt att tolka ett budskap; dominant, oppositionell eller förhandlande tolkning. I en dominant tolkning godtar mottagaren budskapet, medan den oppositionella tolkningen innebär att mottagaren vänder sig mot budskapet.

At present indoor tethering of dairy cows is still common but is not predicted to take part of modern dairy production. When conducting scientific studies of cattle it is generally necessary to tether the animals to maintain a controlled environment. Studies confirm that tethering and confinements of cattle severely affects the development of stereotypies in cattle. The feeding regime and feeding level have an immense affect on the stereotypi level in cattle. The aim of this experiment was to study dairy heifers that had never been tethered before the start of the experiment, to evaluate the affect of tethering on the development of stereotypies and the impact of the feeding regime on the behavior of the animals. Sixteen dairy heifers were tethered in a tie stall and divided in two groups with different treatments. Heifers in treatment E were fed restrictedly with silage and treatment EH was fed with the same amount of silage but also straw ad libitum.
