Effekt av fôrstyrke i kvigeoppdrettet på fødselsvekt, avvenningsvekt og kalvingsvansker i ammekuproduksjon
Stutlien, Guro Sterud (Master thesis, 2019)Hensikten med denne oppgaven var å undersøke hvordan fôrstyrken i kvigeoppdrettet påvirker fødselsvekt, avvenningsvekt og kalvingsvansker i ammekuproduksjon. Fôrstyrke ble definert ut fra fôropptak i antall FEm (fôrenheter), ... -
Estimation of breed and heterosis effects for cow productivity, carcass traits and income in beef × beef and dairy × beef crosses in commercial suckler cow production
Wetlesen, Marit Smith; Åby, Bente Aspeholen; Vangen, Odd; Aass, Laila (Peer reviewed; Journal article, 2020)This study aims to investigate calving difficulties, birth-, weaning- and carcass weight, herd life of cow, age at slaughter, average daily carcass gain, carcass conformation, carcass fatness and carcass income per carcass, ... -
Faktorer som påvirker kalvingsegenskaper hos norske kjøttferaser og krysninger
Storihle, Mathea (Master thesis, 2016-08-18)I dag er det stor underdekning av norsk storfekjøtt på grunn av redusert antall melkekyr uten tilsvarende økning i ammekutallet, samtidig som etterspørselen etter storfekjøtt har økt. Spesialisert kjøttproduksjon med ammekyr ... -
Farm scale modelling of greenhouse gas emissions from semi-intensive suckler cow beef production
Samsonstuen, Stine; Åby, Bente Aspeholen; Crosson, Paul; Beauchemin, Karen A.; Bonesmo, Helge; Aass, Laila (Peer reviewed; Journal article, 2019)A whole-farm model, HolosNorBeef was developed toestimate net greenhouse gas (GHG) emissions from suckler beef production systems inNorway. Themodel considersdirectemissions ofmethane (CH4),nitrous oxide(N2O) and carbon ... -
Fatty acid profile and intramuscular fat concentration of Musculus longissimus thoracis in bulls fed grass silage harvested at one of three maturity stages, either with or without concentrate supplementation

Klimasmart ammekuproduksjon : simulering av mulige tiltak på gårdsnivå med modellen HolosNorBeef
Konstad, Marie (Master thesis, 2020)For å bidra til begrensning av global oppvarming, arbeider det norske jordbruket for reduserte klimagassutslipp. Dette arbeidet skal ikke gå på bekostning av matsikkerheten (Regjeringen, 2019). En reduksjon i klimagasser ... -

Simulations of feed intake, production output, and economic result within extensive and intensive suckler cow beef production systems
Wetlesen, Marit Smith; Åby, Bente Aspeholen; Vangen, Odd; Aass, Laila (Peer reviewed; Journal article, 2020)The aim of the present study was to investigate the impact of and variation in both maternal and production input traits on the production economy within extensive and intensive suckler cow production systems. By use of a ... -
Suckler cow efficiency – breed by environment interactions in commercial herds under various natural production conditions
Wetlesen, Marit Smith; Åby, Bente Aspeholen; Vangen, Odd; Aass, Laila (Peer reviewed; Journal article, 2020)The significance of breed by environment interaction on suckler cow efficiency traits was investigated, using production data from the Norwegian Beef Cattle Recording System and data collected (feed regimes, etc.) from 27 ... -
Variability in greenhouse gas emission intensity of semi-intensive suckler cow beef production systems
Samsonstuen, Stine; Åby, Bente Aspeholen; Crosson, Paul; Beauchemin, Karen A.; Wetlesen, Marit Smith; Bonesmo, Helge; Aass, Laila (Peer reviewed; Journal article, 2020)Emission intensities from beef production vary both among production systems (countries) and farms within a country depending upon use of natural resources and management practices. A whole-farm model developed for Norwegian ... -
Whole-farm modelling of greenhouse gas emissions from suckler cow beef production
Samsonstuen, Stine (PhD Thesis;2019:93, Doctoral thesis, 2019)The main objective of this thesis was to develop a whole-farm model adapted to the various production systems and natural resources in Norway, estimate the level and variation in greenhouse gas (GHG) emission intensities ...
