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, ... -
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 ...
