Barren rearing environment and early weaning of piglets can lead to a high level of distress, behavioural disturbances and reduction in weight gain. The main aim of this thesis was to study the effects of potential Enrichment objects on piglet?s behaviour and weight gain during the pre- and post-weaning period. The second aim was to examine what type of object stimulated the highest frequency of interaction. The study was carried out at the Swedish Livestock Research Centre in Lövsta where a batch of litters from 10 first-parity Yorkshire sows were used.

The aim with this study is to prepare for a larger study, by gathering information about hunting enrichment, discuss which enrichment Parken Zoo in Eskilstuna have that are suitable to use in the larger study and report which observation methods that are used in other articles. In the larger study, the focus will lie on evaluation methods and measurable results. They have, during several years at Parken Zoo in Eskilstuna, developed different types of hunting enrichments for their carnivores, because hunting is a natural behavior that is hard to accommodate in captivity. The bigger project will integrate other zoos so that they can do a study on a larger group of animals, and because a lot of other studies in the same field only capture the results of few individuals. In this literature study you will read about the goals of enrichment, research that have been done on enrichment for felids and review several specific articles about hunting enrichment for felids..

Environmental enrichment is of high importance for zoos. Borås zoo asked SLU (Swedish University of Agricultural Sciences) for a student to perform a bachelor thesis for them. The task was to develop and evaluate environmental enrichment for their Humboldt penguins. A structure was made, consisting of a sinking skeleton with a floating bridge attached to it. It was presented in an area of the pool that the keepers had experienced that the penguins did not use to any extent.

It is often challenging to create a new enrichment program for any animal. This is especially true with the additional challenge that I wanted to use only naturalistic enrichment, and I?m working with animals some of which are nocturnal. Even with a many hurdles, a little bit of enrichment can do a big difference and make a big difference in activity levels of the animals. Eskilstuna parkens zoo have a house called the MUSeum housing four kinds of rodents.

Unjustified enrichment is used as legal basis when a part claims compensation. Unjustified enrichment can be illustrated as: (A) made a profit on someone else?s loss (B) and if the profit is"unjustified"and has"no legal basis"it shall be returned, which then make it possible for B to claim compensation from A referring to the profit. B has in this case lost something that he owns. To be able to claim A for compensation must the loss of B also be a benefit for A.

That animals should be able to express their natural behaviours, even in captivity, has become a more important issue lately. Nowadays Zoos work much more with educating people and helping conservation projects for endangered species. This is two important reasons for making the environment as natural as possible for zoo animals. Both in captivity and in the wild capuchin monkeys have been seen to use tools such as stones and sticks to get food and are therefore seen as a natural and important behaviour for them. This study was carried out to evaluate a specific sort of environmental enrichment where a group of three capuchins had to use sticks to get different kinds of food out of bottles.

SummaryUnjustified enrichment is an obvious part of the jurisprudence in the majority of countries in Europe. But not in the Nordic countries, and certainly not in Sweden. This depiction of the Swedish posture is based mostly on Hellner?s thesis from 1950. A lot has happened since then, not to mention Sweden?s entry in to the EU.

Clostridium difficile is a pathogen for both humans and animals and is often associated with antibiotic-associated diarrhea. Recently, several human cases of C. difficile-infection with increased mortality and morbidity have been reported. In studies performed in different countries C. difficile has been found in meat.

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.

We understand the world around us through categorization and classification. But things are morecomplex than that, life is mixed up, flowing and unable to stick to labels. The main purpose ofcorpus is to contain, organize and control food and beverages. Corpus objects are also socialmarkers that have a tradition of being elitist; in both choice of material and in that they imply acertain way of usage. Corpus objects are heavily loaded with tradition and rituals.

Cheetahs in the wild are declining due to hunting, lack of prey, exploitation of habitats and loss of cubs to predators. Those are the main reasons to why cheetahs are kept in captivity today for conservation. Many cheetahs kept in captivity are seen pacing ? a behaviour that arise when the animal is prohibited from performing natural behaviours. It is believed to being attributed to a lack of stimulation in the environment where they are being held.

The purpose of this paper was to identify the elements and the alloys that five objects found in Birka consist of and to examine whether there are any significant differences between the presumably imported and domestic objects. The material was analyzed using a scanning electron microscope (SEM) which was equipped with an energy dispersive X-ray spectrometer (EDS) in order to identify the elements that are present and the alloys that the objects are made of. Then the SEM results were compared with the results of previous analyzes that have been performed on finds from Birka in order to investigate how the objects differ in elemental composition and to find out if there are any significant differences between them. The results showed that the objects? content of the elements analyzed varies as the copper alloys the objects are made of.

This study was made on former agricultural areas that had been planted with spruce or pine, in the county of Västerbotten. The goal of the project was to investigate suspected deficiency of boron in these areas. Several objects have been reported for possible deficiency and some of these have the characteristic symptoms of boron-deficiency. The hypotheses are that 1) Boron deficiency is present at several of the investigated objects. 2) Planting of forest on cultivated postglacial sediments leads to a successive podzolisation with a decreasing content of organic matter in the mineral soil, due to decomposition, and a decreasing pH in the soil, even on locations that have been added lime. To be able to confirm or reject the hypotheses a number of tests were performed.

The objective of this study was to contribute with suggestions of nature preservation managements of selected forest objects of high nature values managed by the Swedish state-owned forest company Sveaskog. Many forests with high natural potential are relatively rare today due to modern forestry, where wood production is the main purpose. Sveaskog?s policy is to consider and to priority nature conservation on valuable objects. This assessment includes objects that in the future may develop into nature reserves.

Due to the climate change natural disasters expects to increase and in some areas the conditions for dissemination of hazardous pollutants from contaminated areas could be affected. Different inventories and mapping has been made to identify areas of risk for flood or avalanche around the country. At the same time inventory and treatment of potential polluted areas (MIFO objects) is progressing. In Ljungans run of area in Västernorrlands county is a exposed area due to the amount of clay and silt in the ground that are sensitive in the context avalanche. The area has also a lot of MIFO objects and risks of flood.This essay aims to investigate what data material that is available regarding MIFO objects, flood- and avalanche risks in Ljungans run of area in Västernorrlands county.
