Tid brukt til beiting hos STN ammeku, på kultur- og utmarksbeite

Beiteadferden på fjellbeite og innmarksbeite i lavlandet hos kyr av rasen Sidet trønder- og Nordlansfe (STN) med diekalver blei studert i tre perioder av beitesesongen. I de to første periodene, juni og juli, brukte dyra i fjellet mer tid på å gå enn de på innmarka. For de andre aktivitetene var det små forskjeller. Det var likevel en tendens til at dyra i fjellet brukte mindre tid på å beite og til å stå enn de som gikk på innmarksbeite

Pasture Utilization at Islands in Northern Norway

The Norwegian sheep industry is based on utilization of “free” rangeland pasture resources. Use of mountain pastures is dominating, with about two million sheep grazing these pastures during summer. Regional challenges related to e.g., loss of sheep to large carnivores make farmers think differently. The Norwegian coastline is among the longest globally and is scattered with islets and islands. Alone along the coast of Nordland county, it is estimated more than 14,000 islands. Use of islands for summer pasture is an alternative but there is a limited knowledge about such a management system. In this study, we examined lambs’ average daily gain on island pastures at the coast of Norway. In total 230 lambs on three islands (Sandvær, Sjonøya, and Buøya), with varying pasture quality and stocking rate, for 3 years (2012, 2013, and 2014). At Sandvær as much as 92% of the island was characterized as high nutritional value while at Sjonøya and Buøya only 15%, was characterized high nutritional value. We found an average daily lamb growth rate of 0.320 kg d−1. Lambs on Sandvær had a higher daily gain (P \u3c 0.05) than those on Sjonøya and Buøya, and lambs’ average daily gain was significantly lower (P \u3c 0.05) in 2013 compared to 2012 and 2014. We conclude that with a dynamic and adaptive management strategy there is a potential to utilize islands for sheep grazing during summer

Verminderung von HKW-Emissionen durch die Entwicklung eines Verfahrens zur Rueckgewinnung und umweltfreundlichen Spaltung. Teilvorhaben 2 Abschlussbericht

The research and development project 'Reduction of halogen-carbonhydrogen-emissions by developing a recycling- and cracking-process, project part II' is the first successful approach to reach a technology for the disposal of coking substances containing PU-isolating foams under the most strictly standards with respect to environmental as well as economical aspects and with flexibility in application. The innovative Crack-Condensation-Process thus contributes to solve the problem of disposing accumulated halogen-carbonhydrogenic waste - a problem that is increasingly acknowledged by experts as well as in the general public.

Differences in choice of diet between sheep breeds grazing mountain pastures in Norway

In the present study, the foraging behaviour of ewes from three common Norwegian sheep breeds; the long-tailed Dala sheep, and the two short-tailed breeds Spael sheep and Norwegian Fur sheep was studied. Based on difference in body size and digestive anatomy, we expected the lighter short-tailed ewes to browse more on woody plants than the Dala ewes. The experiments were conducted during two consecutive summers within the flocks' usual grazing areas, and we sampled the proportion of grazing time that ewes spent feeding on woody plant species. We tested the hypothesis by applying generalized linear mixed models to the feeding behaviour data. As predicted, the short-tailed ewes spent substantially more of their grazing time browsing on trees, bushes and heather compared to the Dala ewes. We discuss the results in the context of maintaining the, now threatened, pastoral landscapes of mountainous regions of Norway; short-tailed breeds should be more effective than the Dala breed in reducing tree and bush encroachment, but more detailed studies are needed to quantify the breed differences in this respect

Strategies to mitigate greenhouse gas emissions from pasture-based sheep systems - an EU project consortium view.

ABSTRACT. - An international project ('Grass To Gas', 2019-2024) to combine expertise and generate new knowledge for the reduction of the potent methane (CH4) greenhouse gas (GHG) from sheep is underway. Aims are to validate predictors of feed intake, methane emissions and feed efficiency, to investigate the association between feed efficiency and methane emissions measured indoors and outdoors, to explore the opportunity of using genetics and genomics (animal and microbiome) to reduce methane emissions in pasture-based sheep systems and quantify the economic and environmental benefits of more feed-efficient and lower GHG-emitting sheep linked to their microbiome. The potential impact is to deliver applied, sustainable solutions to reduce methane emissions for the international sheep breeding community, by bringing together the latest precision livestock monitoring and molecular technology to identify novel selection targets and potentially candidate genes
