11	En jämförelse av beteendeeffekter hos slaktsvin av olika typer av miljöberikning / A comparison of behaviour in fattening pigs with different types of environmentalenrichments Nygren-Fasth, Veronica January 2014 (has links) Hos grisar finner man flera stereotypiska beteenden, som rörbitning och svansbitning. Dessa beteenden är relativt vanliga hos grisar. En miljöberikning definieras som förbättring av ett djurs välfärd, både psykologisk och fysiologiskt, genom förändringar hos djurets omgivning. Denna studie har undersökt om miljöberikningar kan minska stereotypiska beteenden hos grisar. De två olika miljöberikningar som har använts är en jutesäck fylld med halm och en Jolly Ball™. De tre stereotypiska beteendena som studerades var rörbitning, svansbitning och bukmassage. Studien utfördes på 107st grisar uppdelade på 12 boxar, under totalt tre veckor. Alla tre stereotypiska beteenden minskade statistiskt signifikant . Detta visar att båda miljöberikningarna hade en positiv effekt på grisarna då de minskade deras stereotypiska beteenden. De interagerade mer med jutesäcken fylld med halm än vad det gjorde med Jolly Ball™. Grisarna föredrog den miljöberikningen som var omformbar, förstörbar, ätbar, tuggbar, vilket går i linje med liknande studier. / Among fattening pigs you find several stereotypical behaviours, such as bar-biting and tail-biting. These behaviours are quite common among domestic pigs. Environmental enrichments are often used to reduce stereotypical behaviours in animals. An environmental enrichment is defined as an improvement of an animal’s welfare, both psychologically and physiologically, through changes in the environment of the animal. With this study, different environmental enrichments were studied to see if they can reduce stereotypical behaviour among fattening pigs. The two different environmental enrichments used were a jute sack filled with straw and a Jolly Ball™. The stereotypical behaviours that were looked at were bar-biting, tail-biting and belly-nosing. The study was carried out on 107 pigs divided into 12 pig boxes, during 3 weeks in total. All three stereotypical behaviours decreased significantly. This shows that the environmental enrichments had a positive effect on the pigs, since they reduced their stereotypical behaviour. The pigs interacted more with the jute sack than they did with the Jolly Ball™. The pigs preferred the environmental enrichment that was destructible, edible, deformable and chewable, which fits well into similar studies that have been executed. domestic pig fattening pigs environmental enrichment abnormal behaviour belly-nosing tail biting bar biting farming slaktsvin grisar svin miljöberikning

13	Gårdsbaserad biogas på Nya Skottorp : utvärdering och optimering av anläggningen och uppgradering av biogasen Kalén, Jonas, Åkerlund, Nathan January 2013 (has links) Biogas is an expanding sector within the broad field of agriculture and animal production. Small-scale biogas offers local combined power and heating production and the substrate is transformed into high-quality biological fertilizer. This bachelor thesis focuses on a pig farm in south-western Sweden, where biogas is produced from pig manure, evaluates and suggests ways of optimizing the process and investigates whether investing in an upgrading plant would be a feasible and more cost-efficient option. The results show that the biogas plant is working well, although the production differs from the original plans. This shows in turn that planning and examining the basic conditions before making the investment is of great importance, as well as monitoring and keeping detailed statistics of the running process. Logistical factors make optimizing the process through additional substrates difficult. The thesis shows that investing in a Biosling upgrading plant would be a profitable option, supposing that the upgraded gas is sold via the natural gas infrastructure. Furthermore, many farmers are interested in producing their own fuel for tractors and other machines, which offers more future alternatives for the upgraded biogas. However, biogas producers in Sweden today are not offered any particular subsidies, which makes it especially hard for small-scale producers. biogas methane production farm swine pig manure uppgrading biogas metan metangas gödsel svin gris majs gårdsbaserad lantbruk utvärdering optimering uppgradering biogasproduktion mikrobiologi biosling förnybar energi fordonsgas naturgas Renewable Bioenergy Research Förnyelsebar bioenergi Energy Systems Energisystem
14	Djuren på Gotland : En studie om djurbensmaterialet från två hällkistor på Gotland / The animals on Gotland : A study about animal bones from two cists on Gotland Lindby, Josefine January 2023 (has links) Den här uppsatsen behandlar djurbensmaterial från två senneolitiska/tidigbronsålders hällkistor på Gotland (RAÄ Kräklingbo 12:1 & Burs 9:1). Syfte med uppsatsen var att bidra med kunskap kring djurbensmaterialet som påträffats i hällkistor genom tre frågeställningar. Fysiskt djurbensmaterial har genomgått en osteologisk analys och sedan jämförts med två andra hällkistor från samma period samt översiktligt med andra stenålderslokaler på Gotland. Resultatet visade en ökning av får/get samt nötkreatur samt en minskning av svin och säl gentemot tidigare perioder. Häst, hund, mindre däggdjur, fågel och fisk förekom också i materialet. Resultatet visade även indikationer på att skinn/päls/ull varit viktigt för människan. / This study deals with animal bone material from two Late Neolithic/Early Bronze Age stone cist on Gotland (RAÄ Kräklingbo 12:1 & Burs 9:1). The purpose of the study was to contribute knowledge about the animal bone material found in cists through three questions. Physical animal bone material has undergone an osteological analysis and then been compared with two other stone coffins from the same period as well as an overview with other Stone Age sites on Gotland. The result showed an increase in sheep/goat and cattle and a decrease in pigs and seals compared to previous periods. Horse, dog, smaller mammals, bird and fish also appeared in the material. The results also showed indications that skin/fur/wool had been important to humans.
