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, ... -
Betydningen av grovfôrkvalitet på lønnsomheten i melkeproduksjon
Hol, Karoline (Master thesis, 2017)Denne masteroppgaven har som formål å undersøke sammenhengen mellom grovfôrkvalitet og kostnadene ved produksjon av grovfôret, og hvordan grovfôrkvaliteten påvirker lønnsomheten av driften. Ut i fra denne overordnete ... -
Bunkers or round bales: Losses and silage quality with or without acid treatment of low dry matter grass crops
Randby, Åshild Taksdal; Bakken, Anne Kjersti (Peer reviewed; Journal article, 2021)Grass clover crops were harvested with or without application of 4 L/t of a formic- and propionic acid-based silage additive and ensiled in one bunker silo and 6 round bales per treatment in each of three harvests. The ... -
Effect of acid based additive treatment of low dry matter grass crops on losses and silage quality in bunker silos
Randby, Åshild Taksdal; Bakken, Anne Kjersti (Peer reviewed; Journal article, 2021)The large surface area of bunker silos imposes challenges with heating caused by plant respiration during initial ensiling. This study aimed to explore if application of a formic- and propionic acid-based additive would ... -

Effect of maturity stage at harvest and kernel processing of whole crop wheat silage on digestibility by dairy cows
Randby, Åshild Taksdal; Nadeau, Elisabet; Karlsson, Linda; Johansen, Astrid (Peer reviewed; Journal article, 2019)The study aimed to explore whether digestibility by cows of whole crop wheat silage harvested at two different dough stages of maturity was impaired due to its content of whole kernels. Wheat was harvested at early (ED) ... -
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 ... -
Effekt av søye- og lammestell fra lamming til slipp på sommerbeite på lammenes overlevelse og tilvekst
Lien, Håvard (Master thesis, 2016-08-16)Siden tidlig på 2000-tallet og frem til i dag har lammedødeligheten i norske besetninger hatt en svak økning om våren. Gode rutiner fra lammene blir født til de slippes på sommerbeite er viktig for å unngå dødelighet og ... -
Effekt av ulike konserveringsmetoder for bygg på melkekvalitet i økologisk landbruk
Adler, Steffen Andreas; Randby, Åshild Taksdal (Grønn kunnskap e;, Research report, 2005)Effekten av tre ulike konserveringsmetoder for bygg på fôropptak og melkekvalitet i økologisk landbruk ble testet i et fôringsforsøk med cross over design med tre perioder á en uke. Kyrne ble tildelt 6,0 kg TS (førstekalvskyr ... -

How body condition, current nutrition and Finn gene status influence litter size in Norwegian White Sheep : a study in flushing and antiflushing
Gløersen, Martin Opheim (Master thesis, 2020)The effect of body condition, current nutrition and Finn gene status on litter size was studied using 111 ewes of Norwegian White Breed, in the age from 1.5 to 6.5 years. The last 11 weeks before mating in mid-November the ... -
