Influence of the development stage of perennial forage crops for the recovery yields of extractable proteins using lactic acid fermentation

| Type artikkel: Publisert studie

Kategori: Fôr, Prosessering

The extraction of leaf proteins from perennial forage crops within a green biorefinery concept represents a promising approach to face the increasing demand for protein arisen in the organic farming sector to feed monogastric animals. Given the background, the present research aims at assessing the protein extractability from three plant species i.e. chicory, red clover and timothy, at different development stages and investigating lactic acid fermentation as the key method for the extraction of leaf proteins.

High-fiber rapeseed co-product diet for Norwegian Landrace pigs: Effect on digestibility

| Type artikkel: Publisert studie

Kategori: Gris, Husdyr, Kjøtt

The effect of partially replacing soybean meal (SBM) and wheat with high-fiber rapeseed (RS) co-products on the nutrient and energy digestibility of 40 Norwegian Landrace pigs (17.8 ± 2.7 kg initial BW) was investigated. Pigs were fed a pelleted diet containing 200 g/kg of a coarse fraction of air-classified rapeseed meal (RSM) and 40 g/kg of RS hulls or a SBM control diet (20 pigs/dietary treatment) for 3 wk to estimate apparent ileal (AID) or total tract (ATTD) digestibility of energy and nutrients, organ weight, intestinal histomorphology, and digestive enzyme activities of individual pigs.

Målrettet fôrprosessering – et redskap til øke utnyttingen av energi og protein hos melkekyr

| Type artikkel: Forskningsprosjekt

Kategori: Husdyr, Melk, Storfe

Høytytende melkekyr setter store krav til innhold av næringsstoffer i rasjonen. For å tilfredsstille kravene blir kyrne gitt økende mengder fôr med høyt innhold av protein og stivelse. I Europa, og spesielt Norge, er selvforsyningen av proteinfôr begrenset, og importen høy. For stivelse er selvforsyningen god, men kvalitetene tilgjengelig er utfordrende for vommiljøet og setter begrensninger i hvor mye fôrrasjonen kan inneholde.

Legumes for mitigation of climate change and the provision of feedstock for biofuels and biorefineries. A review

Humans are currently confronted by many global challenges. These include achieving food security for a rapidly expanding population, lowering the risk of climate change by reducing the net release of greenhouse gases into the atmosphere due to human activity, and meeting the increasing demand for energy in the face of dwindling reserves of fossil energy and uncertainties about future reliability of supply. Legumes deliver several important services to societies. They provide important sources of oil, fiber, and protein-rich food and feed while supplying nitrogen (N) to agro-ecosystems via their unique ability to fix atmospheric N2 in symbiosis with the soil bacteria rhizobia, increasing soil carbon content, and stimulating the productivity of the crops that follow. However, the role of legumes has rarely been considered in the context of their potential to contribute to the mitigation of climate change by reducing fossil fuel use or by providing feedstock for the emerging biobased economies where fossil sources of energy and industrial raw materials are replaced in part by sustainable and renewable biomass resources.
