During an investigation of animal welfare in animal production, the focus has for a long time been focused on the absence of stress, suffering and injuries, and positive emotions have not been prioritized. However, in recent years that has been drastically changed. The public interest have increased for buying animal products from animals that have had a decent life, which have led to that play, exploratory behavior and other positive behaviours has come to play a significant role in welfare assessment. The welfare of cattle is difficult to assess since there is currently no ancestors to study, it is thus difficult to determine which behaviors can be regarded as natural and thus positively related, acordingly the welfare of cattle have been forgotten and research on positive emotions of cattle have not been prioritized. The aim of this study was to observe which behavior growing cattle performe, and if there was any differences of which kind of behavior that was observed, if the cattle is keept on slatted floor or on a deep straw bedding. Furthermore, antoher purpose was to investigate if the observed behaviours indicate a positive, negative or natural welfare, and if it is possible to use the observed behaviours in a welfare assessment.

Weaning is one of the most critical events in the piglet production with problems such as growth check and post-weaning diarrhea as a result. The lighter the piglets are when the growth check occurs, the harder they have to get back to normal growth rate. Creep feeding of piglets is used to reduce the problems by increasing the weaning weight and adapting the digestive tract to a starter diet. Hodge (1974) showed that the sow?s milk can not provide enough nutrients for maximal growth rate.

The impact of the distribution in the soil volume of two farm manures on the net mineralization and immobilization processes of nitrogen were studied in an incubation experiment. Cattle slurry and broiler litter were placed in the soil with three procedures for incorporation including placement on top of the soil (TOP), in the middle of the soil (MID) and mixed homogenously with the soil (MIX). During the two weeks of incubation, few significant differences in net mineralization were seen between TOP, MID and MIX. However, there was a tendency that MIX led to a larger net immobilization of N than placement at one point (TOP and MID). This is also the result in the literature.

Oxytocin is today widely spoken of as a "feel good" hormone. Recent research has increased interest in the hormone and its role in social and sexual interactions, as well as its importance for complex behavioral patterns. There is evidence that oxytocin is released during physical contact and is said to suppress anxiety and stress. In animals and humans, oxytocin, which is a neuropeptide and likewise a hormone, is necessary for parturition and lactation. Synthesis of oxytocin occurs in brain neurons and in specific organs involved in reproduction.

During the late 1800s fire suppression became increasingly effective in northern Sweden which led to decreased areas of fire-disturbed woodland and successive changes in the structure of forests. In the long run this can pose a serious threat to fire-dependent and fire-favored species. Today some fire-prone forest reserves are burned as a nature conservation act. Often partial cuttings are made before burning, with somewhat different motives. The purpose of the study in LÃ¥ngsidberget nature reserve was to give a general picture of forest history and its affect on today?s forest condition, and to show how partial cuttings affect burning conditions and results. LÃ¥ngsidberget is located close to areas that were colonized during the Middle Ages.

A study was made to evaluate how current measurementscould help to determine how particles from fish farms are dispersed. During sixweeks of the summer 2012, two different current measurements were conducted.One of them consisted of measurements each fifth minute at 5 m and 15 m atthree locations for 14-16 days each. The other consisted of profilemeasurements at each location at four times during the period of six weeks. Forthe current measurements two instruments (model RCM 9) were used. A two weekmeasurement can give enough data to make an evaluation of how the currents at alocation will transport litter from a fish farm.

Tillexempel bostädernas möjligheter till genomgående siktlinjer och möjlighet till ljusinsläpp från olika riktningar..

Studien syftet är att undersöka om barn som har ammats längre än ett år har ökad risk för karies före sex års ålder. Metoden är en systematisk litteraturstudie där databaserna Cinahl, Cocharane och PubMed har sökts. Resultatet baserades på fyra kohortstudier och tio tvärsnittsstudier. Resultatet av dessa fjorton studier kan indelas i två riktningar, studier som visar att amning längre än ett år ökar kariesrisken och studier som indikerar att amning inte ökar risken för karies. Slutsatser: Utifrån resultatet av artiklarna får det anses att det vetenskapliga underlaget är otillräckligt för att hävda att amning ökar risken för kariesutveckling..

Sheep production is the only animal production in Sweden that is increasing. Therefore,increasing knowledge of the production is of great interest. In order to run a viable sheepproduction, producers needs to be successful in the breeding of the animals and achievean economic surplus in the end. Lambs that are born healthy and vital have greaterconditions to perform high lamb weight gains and thus a successful production. Thereare many factors affect the survival, birth weight and early weight gain of the new bornlamb.

Genom att ge små glimtar lockas besökaren att besöka de samlingar av modern och klassisk konst samt den samling av grafiska tryck som finns på utställning. Formen tillåter rörelse i alla riktningar och förlänger kajen. Byggnaden är utformad i trä som är konturskuren på ytterskiktet med en stomme av ett rymdfackverk i stål.

Arbetet går ut på att för Nybro Cementgjuteri utföra dimensioneringsberäkningar för infästningsplåtar ingjutna i prefabricerade betongelement. Genom att utföra dessa beräkningar har ett beräkningsunderlag i Microsoft Excel kunnat framställas och levereras till företaget. I underlaget kan företaget föra in olika plåtparametrar som bredd, höjd och tjocklek pa? plåten samt förankringsstängernas längd och tjocklek med mera och få ut vilka kapaciteter plåtarna besitter gällande normalkraft, tvärkraft samt moment i tre olika riktningar.Dessutom har en parameterstudie utförts där det har undersökts vilka konsekvenser det skulle medföra att till exempel ändra avståndet mellan förankringsstängerna..

Lars Levi Læstadius (1800-1861) var en stor och viktig människa. Han är ihågkommen och mycket omskriven. Læstadius var en aktiv nykterhetskämpe, botaniker och älskad präst. Utöver detta var han även den som grundade den märkliga väckelsen omkring år 1845 som än idag bär hans namn: læstadianismen. Læstadianerna, som de troende kom att kallas, lyssnade till denne stränga man och lärde sig att leva som han predikade, ett enkelt och nyktert liv.

A reward cycle for investigating the emotional status in animals has been developed and it requires that animals go through three main phases, i.e. anticipation, consumption and relaxation. The reward cycle has not been tested previously for access to play in pigs. Therefore, the aim of this Master thesis was to investigate if growing pigs showed more behaviours indicative of excitement than pigs that were not allowed to play, performed play in a play arena and showed more behaviours indicative of relaxation after play when they were back to their home pen than pigs that were in their home pen the whole time. Forty undocked piglets (10 litters of Specific Pathogen Free half pure-bred Yorkshire and half hybrids of Yorkshire x Landrace balanced for breed between two treatments were used.

In 1993, Sweden signed the Convention on Biological Diversity and thus agreed to conserve our indigenous biological diversity. As a part of the convention, Sweden is obliged to conserve a number of domestic animal breeds and among them the Linderöd pig. In 1952, the zoo, Skånes Djurpark, took care of a pregnant sow that was regarded to be related to the old "forest pig". The old forest pig was thought to have been extinguished by the early 20th century as a result of the ban on boars not approved by state inspectors. However, according to later accounts, several farmers still kept some of these non-approved pigs.
