2. 16. Cattle grazing on semi-natural pastures : animal behaviour and nutrition, vegetation characteristics and environmental aspects

   Author : Maja Elisabeth Pelve; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
   Keywords : LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES;

   Abstract : The knowledge of the grazing behaviour of cattle on Swedish semi-natural pastures and how this relates to the nutritional quality and quantity of the vegetation is low. In a situation where farming is being intensified both nationally and globally, it is important to gain more information about semi-natural pastures and how to utilise this resource properly.

4. 17. Sanitisation of faecal sludge by ammonia : treatment technology for safe reuse in agriculture

   Author : Jörgen Fidjeland; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

   Abstract : Faecal sludge contains valuable plant nutrients and can be used as a fertiliser in agriculture, instead of being emitted as a pollutant. As this involves a risk of pathogen transmission, it is crucial to inactivate the pathogens in faecal sludge. One treatment alternative is ammonia sanitisation, as uncharged ammonia (NH₃) inactivates pathogens. READ MORE

5. 18. Population History and Non-invasive Monitoring : Use of low copy number DNA in Conservation Genetics

   Author : Øystein Flagstad; Ettore Randi; Uppsala universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Biology; genetic tagging; immigration; loss of genetic variability; non-invasive molecular techniques; population decline; Swayne’s hartebeest; wolf; wolverine; Biologi; Biology; Biologi; ekologisk botanik; Ecological Botany;

   Abstract : Conservation genetics research is increasingly becoming an integrated part of the management of small and endangered populations. In this thesis I developed tools for genetic analysis of low copy number sources of DNA, such as old teeth from museum specimens as well as field-collected faeces and urine. READ MORE

6. 19. Biomarkers for colon cancer : applications in human and rat studies

   Author : Pernilla C. Karlsson; Karolinska Institutet; Karolinska Institutet; []
   Keywords : Colon cancer biomarkers; faecal water; polyethylene glycol; synbiotics; COX-2 inhibitors;

   Abstract : Colon cancer is one of the major causes of cancer in industrialized countries, and it is caused by a combination of hereditary, environmental and dietary factors and lack of physical activity. Of these factors, diet is one of the most important. READ MORE

7. 20. Assessing phosphorus overfeeding in dairy cows

   Author : Maria Nordqvist; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
   Keywords : LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES;

   Abstract : Faecal total phosphorus (TP) from dairy cows consists of a largely insoluble fraction and a soluble P fraction (SP), which mainly represents excess P. The soluble fraction increases proportionately with increased P feeding as excess P is mainly excreted with the faeces in soluble form. READ MORE
