Om faggruppen
Våre sentrale forskningsområder er fôrevaluering og -optimalisering, fôrteknologi, utvikling og utnyttelse av nye fôrråvarer, bærekraftig utnyttelse av nasjonale fôrressurser, reduksjon av klimagassutslipp, mikrobiota, produktkvalitet, samt innendørs management og beitesystemer.
Vi tilbyr forskningsbasert undervisning innen ernæring av drøvtyggere og hest, fysiologi, fôrproduksjon, beiteøkologi og beitebruk, mjølk- og kjøttproduksjon, produksjonssykdommer og reindrift.
Faggruppen har tilgang til og bruker topp moderne forskningsinfrastruktur for å utføre fremtidsrettet forskning og undervisning. Den viktigste forskningsinfrastrukturen for gruppen er Stoffskifteavdelingen hvor vi utfører grunnleggende in vivo-, in vitro- og in saccoforsøk. Senter for husdyrforsøk og Senter for fôrteknologi leverer infrastruktur for henholdsvis produksjonsforsøk med drøvtyggere og for produksjon av spesifikke kraftfôrtyper til forsøk. Kjemiske analyser utføres ved LabTek
