  1. 1. Hållbar boskapsproduktion : växthusgaser från nötkreatur och möjliga strategier för minskade utsläpp

    Kandidat-uppsats, SLU/Dept. of Animal Environment and Health

    Författare :Julia Bonevik; [2019]
    Nyckelord :koldioxid; lustgas; metan; silvopastoral; ekologisk;

    Sammanfattning : Hållning av nötboskap genererar utsläpp av de tre växthusgaserna koldioxid, lustgas och metan. Alla tre har stor betydelse för klimatet på jorden då de bidrar till den pågående globala uppvärmningen. Utsläpp från dessa växthusgaser kan delas in de som kommer direkt ur korna samt indirekta utsläpp som genereras vid skötseln av dem. LÄS MER

  2. 2. Changing Agriculture : Stable isotope analysis of charred cereals from Iron Age Öland

    Master-uppsats, Stockholms universitet/Arkeologiska forskningslaboratoriet

    Författare :Markus Eklund; [2019]
    Nyckelord :barley; wheat; oat; rye; carbon; nitrogen; isotope; FTIR; manuring; ecology; systems; networks; climate; resilience; entanglement; migration period; Sandby; Gråborg; Skedstad; Prästhag;

    Sammanfattning : The Middle Iron Age on Öland (around 200-550 AD) is often regarded as a prosperous period witha wealth based on animal husbandry. In this study charred cereals from several Iron Age sites atÖland are studied to answer questions about prehistoric diet and agricultural practices. LÄS MER

  3. 3. The Effect of Agricultural Intensification on Nitrate Concentrations in Shallow Groundwater in Two Watersheds in Ethiopia

    Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Institutionen för geovetenskaper

    Författare :Anna Larsson; [2019]
    Nyckelord :agricultural intensification; Ethiopia; fertilisers; groundwater; nitrate; watershed; avrinningsområde; Etiopien; grundvatten; gödslingsmedel; jordbruksintensifiering; nitrat;

    Sammanfattning : Sustainable intensification of agricultural will be crucial in the future to feed a growing population and address ongoing climate changes. Ethiopia is still dominated by traditional agricultural practices and the population is expected to increase from todays 110 million to 174 million in 2050, making sustainable implementations of intensified agricultural methods crucial.

  4. 4. Feeding the 45 million : substituting soybean protein with insect protein within EU poultry and egg production

    Master-uppsats, SLU/Dept. of Ecology

    Författare :Douglas Hunter; [2019]
    Nyckelord :insects; insect production; livestock feed; entomophagy; land use; futures research; food security; energy security; black soldier fly; mealworm; house cricket; sustainable development;

    Sammanfattning : A global population increasing both in number and in resource consumption per capita has resulted in food, livestock feed and energy crop demands that are increasingly difficult to meet on rapidly degrading soils within a diminishing available area of arable land. With further expansion of agricultural land infeasible and yield increases through further intensification insufficient to meet the scale of predicted crop demand, the use of insects as an animal feed has gained traction as a method of not only reducing competition for arable land, but also some of the detrimental environmental consequences of livestock and conventional feed production.

  5. 5. Effects of silage and haylage on feed intake, growth and health in two meat type chicken genotypes

    Master-uppsats, SLU/Dept. of Animal Nutrition and Management

    Författare :Temwanoku Ioakim; [2018]
    Nyckelord :silage; haylage; broiler hybrid; feed intake; growth; health;

    Sammanfattning : In this project the effect of grass silage and haylage on feed intake (FI), growth and health of two meat type chicken hybrids, Ross 308 and Rowan Ranger were studied. The study was carried out at the Swedish Livestock Research Center, located in Funbo-Lövsta, Uppsala for a period of 42 days. LÄS MER
