Effekt av AH1 på dødfødsler og tidlig utrangering av kalv hos NRF
(Master thesis, 2018)Genet AH1 ble oppdaget i 2014 på Canadisk Ayrshire og studien viste at dersom begge foreldre er bærere av AH1 kan det medføre dødfødsel. Formålet med denne studien var å undersøke om AH1 har negativ effekt på kalvingsegenskapene ... -
Dominans av flerårig raigras (lolium perenne L.) i ulike artsblandinger : konsekvenser for avling og fôrkvalitet
(Master thesis, 2018)Flerårig raigras (Lolium perenne L.) er en mye brukt fôrvekst i tempererte områder på grunn av god fôrkvalitet og toleranse for intensiv drift. I Norge har derimot arten ofte ikke blitt inkludert i produksjonen på grunn ... -
Estimation of endogenous loss from soy variants using the 15N isotope dilution method in Atlantic salmon (Salmo salar)
(Master thesis, 2018)True digestibility of feeds and feed ingredients is difficult to measure in fish, partially due to methodological challenges in quantifying endogenous losses that are mixed with undigested materials originating from the ... -
Weed invasion in different species compositions with and without perennial ryegrass
(Master thesis, 2018)Though perennial ryegrass (Lolium perenne) is a desired species in roughage production because of its nutritive qualities, it is not very persistent and - when used in species mixtures - often disappears after the first ... -
