Publications
NIBIOs employees contribute to several hundred scientific articles and research reports every year. You can browse or search in our collection which contains references and links to these publications as well as other research and dissemination activities. The collection is continously updated with new and historical material.

The main objectives under this programme were: - To improve organising, content and quality of academic education and research in agriculture, veterinary medicine and forestry to meet with needs for qualified people in ongoing rebuilding after wars and to reach the general European level and standards. - Create functional and sustainable networks of regional institutions and professionals to support each other and cooperate for optimal use of limited available resources in the SEE region in a difficult rebuilding situation. The main activities were: - Research and development projects in the areas of animal sciences, crop and fodder production and use of GIS-methods in forestry and agriculture. - Support to development of staff and institutions in form of study stays, study material, covering of costs for laboratory analysis etc. related to M.Sc. and Ph.D. thesis work, guest lecturing and some equipment. - Support to reorientation of academic education in agriculture, forestry and veterinary medicine: Support to regional networks, professional meetings, further development and use of the Programme web site and web-based teaching.The most important strategy in this Programme was to facilitate for institutional cooperation and network building between partners in the SEE area. Therefore a broad approach was chosen with a large number of partners (16) from all actual geographical areas in SEE - West Balkan - (Albania, Bosnia & Herzegovina, Croatia, Kosovo, Macedonia and Serbia & Montenegro) and representing most of the different ethnical groups in the region. The main intensions under the new programme is to improve the organisation, content and quality of academic education, research and support services in the faculties of agriculture, veterinary medicine and forestry in order to meet national needs in the ongoing reconstruction after the regional wars. Programme activities include activities that: Support and strengthen selected institutions in SEE/WB towards obtaining European professional levels and standards. Promote networking and scientific cooperation between the SEE/WB institutions. Promote networking and scientific cooperation between institutions in SEE/WB and in Norway.

The objectives of this study were to investigate whether there were differences between Norwegian Red cows in conventional and organic farming with respect to reproductive performance, udder health, and antibiotic resistance in udder pathogens. Twenty-five conventional and 24 organic herds from south-east and middle Norway participated in the study. Herds were matched such that geographical location, herd size, and barn types were similar across the cohorts. All organic herds were certified as organic between 1997 and 2003. All herds were members of the Norwegian Dairy Herd Recording System. The herds were visited once during the study. The relationship between the outcomes and explanatory variables were assessed using mixed linear models. Results: There were less > 2nd parity cows in conventional farming. The conventional cows had higher milk yields and received more concentrates than organic cows. Although after adjustment for milk yield and parity, somatic cell count was lower in organic cows than conventional cows. There was a higher proportion of quarters that were dried off at the herd visit in organic herds. No differences in the interval to first AI, interval to last AI or calving interval was revealed between organic and conventional cows. There was no difference between conventional and organic cows in quarter samples positive for mastitis bacteria from the herd visit. Milk yield and parity were associated with the likelihood of at least one quarter positive for mastitis bacteria. There was few S. aureus isolates resistance to penicillin in both management systems. Penicillin resistance against Coagulase negative staphylococci isolated from subclinically infected quarters was 48.5% in conventional herds and 46.5% in organic herds. Conclusion: There were no large differences between reproductive performance and udder health between conventional and organic farming for Norwegian Red cows.

Andreas TreuAbstract
Furfurylation of wood samples can lead to different outcome (different chemistry) and product properties depending on parameters such as pH-value, catalyst, amount of water, time and temperature. Changes in the furfurylation process can even lead to a deterioration of product performance, such as lower durability in comparison to other furfurylated products. How is it possible to detect these changes in chemistry of a furfurylated wood product? To answer this question confocal laser scanning microscopy was used. The expectation was to detect different emissions of the auto fluorescent furfuryl alcohol if differences in chemistry exist. Additionally to the differences in emitted wavelength, the area in the wood structure of different emissions was under investigation. It was the aim to detect whether different product performance of a furfurylated product or different furfurylation processes could be related to changes in chemistry and this was expected to be visualized by CLSM.

Abstract
The coastal heath region along the western coast of Norway, dominated by Calluna vulgaris, is undergoing rapid change. Vegetation changes are caused by changes in management, including reduced frequency or abandonment of periodic heath burning and reduced cutting and grazing. The islands of Froan, in the outermost part of Sør-Trøndelag County in mid-western Norway, are dominated by coastal heath in a state of recession due to reduced traditional land use. The coastal heath is acknowledged as vulnerable and valuable by national environmental authorities, and local landscape management is supported by different national subsidies. The authors mapped the vegetation on Froan and used rule-based GIS-modelling to predict the relative potential for future vegetation changes. The model was based on a range of map layers, including management themes such as history of heath burning and peat removal, current practices of sheep grazing, and also themes derived from the vegetation map, such as soil nutrients, soil moisture and present management status. The resulting model output provides relative probabilities of future changes under different land-use scenarios, and highlights where management efforts should be focused in order to maintain the traditional landscape character.
