A comparison of organic grass-clover silages from primary growth and regrowth in dairy cows
Naadland, Sondre Stokke (PhD Thesis;2016:24, Doctoral thesis, 2017-12-06)The annual milk yield of Norwegian organic dairy cows increased by 18% in 2013 compared to 2007 levels. The increased milk yield in this period was achieved by increased levels of concentrate feed in the diet. Given that, ... -
Associations among nutrient concentration, silage fermentation products, in vivo organic matter digestibility, rumen fermentation and in vitro methane yield in 78 grass silages
Weiby, Kim Viggo Paulsen; Krizsan, Sophie Julie; Eknæs, Margrete; Schwarm, Angela Dagmar; Whist, Anne Cathrine; Schei, Ingunn; Steinshamn, Håvard; Lund, Peter; Beauchemin, Karen A.; Dønnem, Ingjerd (Peer reviewed; Journal article, 2022) -
Effect of organic grass-clover silage on fiber digestion in dairy cows
Naadland, Sondre Stokke; Steinshamn, Håvard; Krizsan, Sophie Julie; Randby, Åshild Taksdal (Journal article; Peer reviewed, 2017)There are differences in grass-clover proportions and chemical composition between herbage from primary growth (PG) and regrowth (RG) in grass-clover leys. Mixing silages made from PG and RG may provide a more optimal diet ... -
Effect of replacing organic grass-clover silage from primary growth with regrowth on feed intake and milk yield of dairy cows
Naadland, Sondre Stokke; Steinshamn, Håvard; Randby, Åshild Taksdal (Journal article; Peer reviewed, 2017)Under Norwegian conditions, diets based on primary growth (PG) silage typically increase milk yield compared to silage prepared from the regrowth (RG). Organic PG, dominated by immature grasses, is often high in energy and ... -
Effect of replacing organic grass-clover silage from primary growth with regrowth on N digestion in dairy cows
Naadland, Sondre Stokke; Steinshamn, Håvard; Krizsan, Sophie Julie; Randby, Åshild Taksdal (Journal article; Peer reviewed, 2016)Clover proportions, and thereby chemical composition of herbage, differ between primary growth (PG) and regrowth (RG) in organic managed grass-clover fields. The characteristics of PG and RG silages suggest different ... -
Effects of supplementing mid-lactation dairy cows with seaweed and vitamin E on plasma and milk α-tocopherol and antibody response to immunization
Kidane, Alemayehu; Nesheim, Ingvild Luteberget; Larsen, Hans J.; Thuen, Erling; Jensen, Søren Krogh; Steinshamn, Håvard (Journal article; Peer reviewed, 2015) -
Effects of three short-term pasture allocation methods on milk production, methane emission and grazing behaviour by dairy cows
Kidane, Alemayehu; Prestløkken, Egil; Zaralis, K.; Steinshamn, Håvard (Journal article; Peer reviewed, 2019)Two short-term grazing experiments were conducted with Norwegian Red cows. In Exp 1, 24 cows were randomly assigned to one of the following three pasture allocation methods (PAM): weekly pasture allowance (7RG), grazing ... -
Effekt av ulike beitemetoder på utslipp av metan hos melkekyr
Neraas, Marte Sofie (Master thesis, 2016-06-02)Globalt representere husdyrproduksjon 14,5 % av antropogene klimagassutslipp, mens landbruket i Norge står for tilsvarende 9 %. Innenfor husdyrproduksjon kommer den største andelen av klimagassutslippene fra metanutslipp ... -
Fatty acid composition,fat-soluble vitamin concentrations and oxidative stability in bovine milk produced on two pastures with different botanical composition
Adler, Steffen Andreas; Dahl, Annette Veberg; Jensen, Søren Krogh; Thuen, Erling; Gustavsson, Anne-Maj; Steinshamn, Håvard (Journal article; Peer reviewed, 2013)Previous research has shown that grazing pastures compared to feeding preserved forages has large impact on milk fatty acid (FA) composition, but differences between grazing red clover (Trifolium pratense L.) or white ... -

Phytoestrogens and Their Metabolites in Bulk-Tank Milk: Effects of Farm Management and Season
Adler, Steffen Andreas; Purup, Stig; Hansen-Møller, Jens; Thuen, Erling; Steinshamn, Håvard (Journal article; Peer reviewed, 2015)Phytoestrogens have structures similar to endogenous steroids and may induce or inhibit the response of hormone receptors. The objectives of the present study were to compare the effects of long-term vs. short-term grassland ... -
Protein characteristics in grass-clover silages according to wilting rate and fermentation pattern
Bakken, Anne Kjersti; Vaga, Merko; Hetta, Mårten; Randby, Åshild Taksdal; Steinshamn, Håvard (Journal article; Peer reviewed, 2016)Effects of wilting rate and fermentation stimulators and inhibitors on protein characteristics of forages typ- ical for organic production were assessed using tradi- tional analytical methods and a gas production in vitro ... -
