| 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... |

| Advantages of low input livestock production on large pastures, including animal welfare, biodiversity and low production costs are challenged by losses due to undetected disease, accidents and predation. Precision livestock farming (PLF) enables remote monitoring on individual level with potential for predictive warning. Body temperature (Tb) and heart rate (HR) could be used for early detection of diseases, stress or death. 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. Eight (27%) of the HR and eight (20%) of the Tb sensors were lost during the study period. Two Tb sensors migrated from the abdominal cavity in to the... |

| NoFence is a GPS-based virtual fencing system to be used for grazing animals. Each animal wears a collar and if crossing a predefined border, the animal will get a sound warning followed by an electric shock. The aims with the two experiments reported in this report were to: 1. To test Nofence on sheep with young lambs focusing on animal welfare and learning. 2. To develop and test a learning protocol for Nofence. 3. To compare the function of Nofence when using it with and without a simple physical fence. In experiment 1, three groups with three ewes and their lambs in each group, were placed on a pasture for four days. At one side of the pasture, there was a Nofence border. The first two days, it was a physical fence outside the border. This fence... |

| 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... |

| 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... |

| The aim of this project was to compare the hygienic quality of the bedding, as well as the parasitic load, cleanliness and lying behaviour in heifers kept on either straw or wood chip deep bedding. Fourteen heifers kept in two pens were housed on straw or wood chip bedding for 43 days, after which the bedding material was switched for 43 additional days. Significantly more mould was found in wood chip than in straw and there was a tendency towards less yeast in wood chip. The heifers had a low faecal parasitic load. The results indicate that the wood chip treatment resulted in somewhat cleaner animals. The heifers had a significantly longer total lying time when kept on straw. In conclusion, wood chip deep bedding could be an option as bedding material,... |

| 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. |
