A genetic study of new udder health indicator traits with data from automatic milking systems
(Peer reviewed; Journal article, 2020) -
A static model for estimating energy content of compound feeds in a dynamic feed evaluation system
(Peer reviewed; Journal article, 2021) -
Accuracy of methane emissions predicted from milk mid-infrared spectra and measured by laser methane detectors in Brown Swiss dairy cows
(Peer reviewed; Journal article, 2020)Since heritability of methane (CH4) emissions in ruminants was demonstrated, various attempts to generate large individual animal CH4 data sets were initiated. Predicting individual CH4 emissions based on equations using ... -
Are farmer assessed temperament, milking speed, and leakage genetically the same traits in automatic milking systems and traditional milking systems?
(Peer reviewed; Journal article, 2020) -
Cyberlindnera jadinii yeast as a protein source in early- to mid-lactation dairy cow diets: Effects on feed intake, ruminal fermentation, and milk production
(Peer reviewed; Journal article, 2022) -
Dynamics of somatic cell count patterns as a proxy for transmission of mastitis pathogens
(Peer reviewed; Journal article, 2019) -
Effect of light intensity, spectrum, and uniformity on the ability of dairy cows to navigate through an obstacle course
(Peer reviewed; Journal article, 2023)The most suitable light intensity for cows during nighttime has not been thoroughly investigated. Recommendations on the night-time lighting regimen on dairy farms differ between countries and range from light throughout ... -
Effects of graded levels of dietary pomegranate peel on methane and nitrogen losses, and metabolic and health indicators in dairy cows
(Journal article; Peer reviewed, 2023) -
Estimation of minimum tolerated milk temperature for feeding dairy calves with small- and large-aperture teat bottles: A complementary dose-response study
(Peer reviewed; Journal article, 2020)At birth, calves are functionally monogastric and remain so for the first weeks of life. Milk in the rumen may cause indigestion, diarrhea, and reduced growth. Calves are often fed cold milk from a large-aperture teat, but ... -
Expression analysis of candidate genes for chronic subclinical mastitis in Norwegian Red cattle
(Peer reviewed; Journal article, 2020)Chronic subclinical mastitis (SCM) is characterized by a long-term inflammation in the udder with high somatic cell count (SCC) in milk. Previously, several novel alternative SCM traits for Norwegian Red (NR) cattle have ... -
Expression analysis of candidate genes for chronic subclinical mastitis in Norwegian Red cattle
(Peer reviewed; Journal article, 2020)Chronic subclinical mastitis (SCM) is characterize by a long-term inflammation in the udder with highsomatic cell count (SCC) in milk. Previously, several novel alternative SCM traits for Norwegian Red (NR) cattle have ... -
Feeding concentrates with different protein sources to high-yielding, mid-lactation Norwegian Red cows: Effect on cheese ripening
(Peer reviewed; Journal article, 2021) -
Genetic (co-)variation of methane emissions, efficiency, and production traits in Danish Holstein cattle along and across lactations
(Peer reviewed; Journal article, 2022) -
Genetic analyses of novel temperament and milkability traits in Norwegian Red cattle based on data from automatic milking systems
(Journal article; Peer reviewed, 2019)The number of dairy cows milked in automatic milking systems (AMS) is steadily increasing in Norway. Capacity and efficiency of AMS are highly dependent on the individual cow's milking efficiency, such as milking speed and ... -
Genetic analysis of semen characteristic traits in young Norwegian Red bulls
