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, 2021-05)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, 2021-05)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 (Journal article; Peer reviewed, 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, 2017-06)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, 2017-03)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, 2016-07-22)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 ulike konserveringsmetoder for bygg på melkekvalitet i økologisk landbruk
Adler, Steffen Andreas; Randby, Åshild Taksdal (Grønn kunnskap e;9(115H) 2005, 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 ... -
Losses and grass silage quality in bunker silos compacted by tractor versus wheel loader
Randby, Åshild Taksdal; Halvorsen, Haakon Nordtveit; Bakken, Anne Kjersti (Peer reviewed; Journal article, 2020-04-27)The study aimed to explore whether an increase in bunker silage density obtained by turning to a heavier packing machine than a farm size tractor would reduce losses and improve grass silage quality and aerobic stability. ... -
Sporedannende bakterier. Utfordringer for mjølkekvalitet, fôrkvalitet og dyrehelse
Johansen, Astrid; Stokstad, Maria; Randby, Åshild Taksdal; Lindback, Toril; Njaastad, Kari-Marie (Bioforsk rapport;8(22) 2013, Research report, 2013-02-08)Rapporten gir en kunnskapsstatus om sporedannende bakterier som har betydning for fôr- og mjølkekvalitet og dyrehelse, kontamineringskilder, årsaker til framvekst i ensilasje, diagnostikk og analysemetoder.
