| Background: It has been questioned if the old native Norwegian sheep breed, Old Norse Sheep (also called Norwegian Feral Sheep), normally distributed on coastal areas where ticks are abundant, is more protected against tick-borne infections than other Norwegian breeds due to a continuously high selection pressure on pasture. The aim of the present study was to test this hypothesis in an experimental infection study. Methods: Five-months-old lambs of two Norwegian sheep breeds, Norwegian White (NW) sheep and Old Norse (ON) sheep, were experimentally infected with a 16S rRNA genetic variant of Anaplasma phagocytophilum (similar to GenBank accession number M73220). The experiment was repeated for two subsequent years, 2008 and 2009, with the use of 16... |

| De største utfordringene for velferden på sau i beiteperioden er sjodogg, fluelarver, alveld og rovdyr (Norges Forskningsråd 2005, Norsk sau og geitavlslag 2001). Økte transportavstander og transporttid samt negativ økonomisk utvikling i saueholdet og en dreining mot mer ekstensive driftsformer gir også grunn til bekymring for velferden til sauen i norsk sauehold. I økologisk landbruk er et høyt nivå på dyrevelferd og god dyrehelse eksplisitte mål (Debio 2003). Muligheten til å utøve naturlig atferd er et viktig prinsipp, og beitedrift er derfor et viktig aspekt i økologisk landbruk. Utfordringene i både økologisk og konvensjonelt landbruk er ofte sammenfallende, men i økologisk landbruk legger en spesielt stor vekt på årsaksorientert problemløsing og... |

| Background: A major challenge in sheep farming during the grazing season along the coast of south-western Norway is tick-borne fever (TBF) caused by the bacteria Anaplasma phagocytophilum that is transmitted by the tick Ixodes ricinus. Methods: A study was carried out in 2007 and 2008 to examine the prevalence of A. phagocytophilum infection and effect on weaning weight in lambs. The study included 1208 lambs from farms in Sunndal Ram Circle in Møre and Romsdal County in Mid-Norway, where ticks are frequently observed. All lambs were blood sampled and serum was analyzed by an indirect fluorescent antibody assay (IFA) to determine an antibody status (positive or negative) to A. phagocytophilum infection. Weight and weight gain and possible effect of... |

| The advantages of low input livestock production on large or unfenced pastures, including high animal welfare, positive impacts on biodiversity and low production costs may be challenged by losses due to undetected disease, accidents and predation. Precision livestock farming (PLF) systems enable remote monitoring on an individual level with the potential for predictive warning. Monitoring body temperature (Tb) and heart rate (HR) could allow for development of early warning systems for not only sickness and behavior, but also oestrus or parturition. In this study, we tested physiological sensors in free grazing Norwegian white sheep in Norway. Forty Tb sensors and thirty HR sensors were surgically implanted in 40 lambs and 10 ewes; 20 lambs in one herd... |

| Saponins from Nartheciumossifragum and / or toxins from cyanobacteria have been found to be hepatotoxic and can cause photosensitization in mammals. In our preliminary study we have looked at whether it is possible to develop a bolus with toxinbinding substances which can be used in the Critical grazing period. We have developed and tested the shape, size and weight of a possible bolus, and conducted a precipitation reaction in a simulated sheep stomach. |

| Norsk senter for økologisk landbruk (NORSØK) og Universitetet i Oslo ved Farmasøytisk Institutt og Institutt for biovitenskap har gjennomført et arbeid for å skaffe mer kunnskap om årsaken til sjukdommen alveld hos lam på beite og undersøke muligheten for å finne forebyggende tiltak som kan hindre opptak av giftstoffer som framkaller sjukdommen. Andre samarbeidspartnere i prosjektet har vært NIVA, NIBIO og representanter for landbruksnæringa. Prosjektene har vært finansiert av Landbruksdirektoratet, Regionalt forskningsfond Midt-Norge, FMLA Sogn og Fjordane, FMLA Møre og Romsdal, Møre og Romsdal fylkeskommune. En spørreundersøkelse blant saueholdere i Sogn og Fjordane, Møre og Romsdal, Sør-Trøndelag og Hedmark viser at dødsårsaken hos lam på beite varierer... |

| Tick-borne fever (TBF), caused by the bacterium Anaplasma phagocytophilum and transmitted by the tick Ixodes ricinus, has considerable consequences for animal welfare and economy in the sheep industry. Non-invasive, objective methods to quantify chronic stress are needed in order to evaluate the welfare impact of disease. The aim of this study was 1) to evaluate hair cortisol (HC) and hair cortisone (HCn) as biomarkers of chronic stress in sheep with TBF and 2) to test whether there was an association between the development of TBF and concentrations of HC, HCn and faecal cortisol metabolites (FCM) and body weight. The experiment took place in an area with a high prevalence of TBF, and thirty lambs were used in the study. Wool samples were collected in... |
