Beiteatferd, habitatseleksjon og produktivitet hos storfe på utmarksbeite
Tofastrud, Morten; Zimmermann, Barbara; Devineau, Olivier; Hessle, Anna; Aletengqimuke, Sukebate; Dickel, Lisa; Hegnes, Hilde; Møllevold, Ole Henrik; Skoglund, Bjørn Holmen; Spedener, Mélanie (Skriftserien;35/2019, Research report, 2019)Politiske målsetninger om økt storfekjøttproduksjon i Innlandet gjør at storfebeiting i utmark er forventet å øke, og da særlig andelen av spesialiserte, internasjonale kjøttferaser. Storfe er avlet til å yte maksimalt på ... -
Classification of behaviors of free-ranging cattle using accelerometry signatures collected by virtual fence collars
Versluijs, Erik; Niccolai, Laura Jeanne; Spedener, Mélanie; Zimmermann, Barbara; Hessle, Anna; Tofastrud, Morten; Devineau, Olivier; Evans, Alina (Peer reviewed; Journal article, 2023)Precision farming technology, including GPS collars with biologging, has revolutionized remote livestock monitoring in extensive grazing systems. High resolution accelerometry can be used to infer the behavior of an animal. ... -
Effects of cattle grazing on young spruce trees in boreal production forest
Spedener, Mélanie; Mathisen, Karen Marie; Hauer, Josh; Hérault, Rémi; Austrheim, Gunnar; Tofastrud, Morten; Zimmermann, Barbara (Peer reviewed; Journal article, 2024)The compatibility of forest livestock grazing with timber production is disputed, as livestock can damage young trees through browsing and trampling. At the same time, livestock grazing might reduce the growth of competing ... -
Forage quality, road and stocking density influence the home range size of free-ranging beef cattle in the boreal forest
Tofastrud, Morten; Møllevold, Ole Henrik; Zimmermann, Barbara (Peer reviewed; Journal article, 2024)This study explores area use of beef cows (Bos taurus) free ranging in boreal production forest of south-eastern Norway. The forests in this region serve multiple purposes, with forestry being the predominant industry. ... -
A Grazer in a Browser's Habitat: Resource Selection of Foraging Cattle in Productive Boreal Forest
Spedener, Mélanie; Tofastrud, Morten; Austrheim, Gunnar; Zimmermann, Barbara (Peer reviewed; Journal article, 2024)In Norway, cattle (Bos taurus) are released to large areas of boreal forest for summer grazing. To determine to what degree this practice challenges timber production and wildlife management, we need a better understanding ... -
Grazing behaviour and weight performance of free-ranging cattle in the boreal forest
Tofastrud, Morten (PhD thesis in applied ecology;18, Doctoral thesis, 2019)En økende interesse for norsk storfekjøttproduksjon basert på utenlandske kjøttferaser har ført til en økning i antall ammekyr på beite i utmarka. Mine hovedmål var å undersøke beiteadferd og vektutvikling hos disse dyrene ... -
Habitat selection of free-ranging cattle in productive coniferous forests of south-eastern Norway
Tofastrud, Morten; Devineau, Olivier; Zimmermann, Barbara (Peer reviewed; Journal article, 2019) -
Microhabitat selection of free-ranging beef cattle in south-boreal forest
Spedener, Mélanie; Tofastrud, Morten; Devineau, Olivier; Zimmermann, Barbara (Peer reviewed; Journal article, 2019) -
Virtual fencing in remote boreal forests: performance of commercially available GPS collars for free-ranging cattle
Versluijs, Erik; Tofastrud, Morten; Hessle, Anna; Serrouya, Robert; Scasta, Derek; Wabakken, Petter; Zimmermann, Barbara (Peer reviewed; Journal article, 2024)Background The use of virtual fencing in cattle farming is beneficial due to its flexibility, not fragmenting the landscape or restricting access like physical fences. Using GPS (Global Positioning System) technology, ... -
Weight gain of free-ranging beef cattle grazing in the boreal forest of south-eastern Norway
Tofastrud, Morten; Hessle, Anna; Rekdal, Yngve; Zimmermann, Barbara (Peer reviewed; Journal article, 2020)Young forest stands and clearcuts in the boreal forest created by modern forestry practices along with meadows of abandoned summer farms may contribute as feeding areas for beef cattle. The patchy distribution and varying ...
