Deterministic modeling of the transmission dynamics of intramammary infections
Rachah, Amira; Dalen, Gunnar; Nørstebø, Håvard; Reksen, Olav; Barlow, John W. (Journal article; Peer reviewed, 2018)We present a novel deterministic modelling approach that describes the transmission dynamics of intramammary infections (IMI) caused by Corynebacterium spp. (Corynebacterium species) in a US dairy herd. Longitudinal, ... -
Dynamics of somatic cell count patterns as a proxy for transmission of mastitis pathogens
Dalen, Gunnar; Rachah, Amira; Nørstebø, Håvard; Schukken, Ynte H; Reksen, Olav (Peer reviewed; Journal article, 2019) -
Factors associated with milking-to-milking variability in somatic cell counts from healthy cows in an automatic milking system
Nørstebø, Håvard; Dalen, Gunnar; Rachah, Amira; Heringstad, Bjørg; Whist, Anne Cathrine; Nødtvedt, Ane C. W.; Reksen, Olav (Journal article; Peer reviewed, 2019)Fully automated on-line analysis equipment is available for analysis of somatic cell count (SCC) at every milking in automatic milking systems. In addition to results from on-line cell counters (OCC), an array of additional ... -
Forskjeller i celletall og andre mastittindikatorer fra melkeroboten i to seleksjonslinjer av NRF
Heringstad, Mari (Master thesis, 2018)Det kommer store mengder nøye og objektivt registrerte data fra melkeroboter (AMS). Dette er data med stort potensialet til å brukes i avlsarbeidet og som styringsverktøy til bonden. Formålet med denne oppgaven var å ... -
Large-scale cross-sectional study of relationships between somatic cell count and milking-time test results in different milking systems
Nørstebø, Håvard; Rachah, Amira; Dalen, Gunnar; Østerås, Olav; Whist, Anne C; Nødtvedt, Ane C. W.; Reksen, Olav (Journal article; Peer reviewed, 2019) -
Milk-flow data collected routinely in an automatic milking system - an alternative to milking-time testing in the management of teat-end condition?
Nørstebø, Håvard; Rachah, Amira; Dalen, Gunnar; Rønningen, Odd; Whist, Anne C; Reksen, Olav (Journal article; Peer reviewed, 2018) -
Multiphase modeling of intramammary infections caused by Corynebacterium species
Rachah, Amira; Dalen, Gunnar; Nørstebø, Håvard; Reksen, Olav; Barlow, John W. (Journal article; Peer reviewed, 2018) -
The detection of intramammary infections using online somatic cell counts
Dalen, Gunnar; Rachah, Amira; Nørstebø, Håvard; Schukken, Ynte H; Reksen, Olav (Journal article; Peer reviewed, 2019) -
Using online cell counts for detection and prediction of subclinical intramammary infections in dairy cows
Dalen, Gunnar (PhD Thesis;2020:14, Doctoral thesis, 2020)Mastitis is an inflammation of the mammary gland that can result in an elevated somatic cell count (SCC). It is mainly caused by intramammary infections (IMI). Cows with mastitis can have clinical signs (clinical mastitis) ...
