  1. 1. Comparing crossbred and purebred dairy cows for economically important traits

    Master-uppsats, SLU/Dept. of Animal Breeding and Genetics

    Författare :Sofie Liedgren; [2022]
    Nyckelord :Crossbreed; Holstein; Montbéliarde; Jersey; Fertility; Production;

    Sammanfattning : The use of dairy x dairy crossbreeding as a breeding strategy has increased in Sweden, which has led to an increase of Brown Swiss, Jersey and Montbéliarde crosses. Multiple studies have been done on Montbéliarde and Jersey crossbreds in the USA but to our knowledge, no such study has been done on Swedish data. LÄS MER

  3. 2. International genomic evaluation of Brown Swiss and Holstein dairy cattle : multi-trait vs. single-trait approach

    Master-uppsats, SLU/Dept. of Animal Breeding and Genetics

    Författare :Sallam Mohammed Abdallah Ahmed; [2020]
    Nyckelord :Genotype-based international genomic evaluation; single trait; multi-trait; reliability; MACE proofs; national proofs; selection index; Brown Swiss; Holstein; Gene by environment interaction;

    Sammanfattning : International genomic evaluation for Brown Swiss population known as InterGenomics, was officially launched in 2011 by Interbull Center in Uppsala, Sweden. The routine evaluation is currently carried out using a single-trait approach where estimated breeding value from multi-trait across countries evaluation (MACE EBV) are used as a dependent variable and genetic corre-lations are assumed to be equal to one between countries.

  4. 3. Low heritability-high variance controversy for dairy cattle disease traits

    Master-uppsats, SLU/Dept. of Animal Breeding and Genetics

    Författare :Maja Winther Iversen; [2014]
    Nyckelord :coefficient of variation; genetic variance; health traits; heritability; progeny groups;

    Sammanfattning : Traits with low heritability estimates such as health and fertility are often assumed to have low genetic variance. However, the heritability is a ratio of additive genetic variance over all variance, and thus, the genetic variation of these traits may only be proportionally small. LÄS MER

  5. 4. ANALYSIS OF THE INFORMATION FLOW AT ABB CORPORATE RESEARCH

    Kandidat-uppsats, Akademin för innovation, design och teknik

    Författare :Jacob Kaffman; Joseph Kaffman; [2014]
    Nyckelord :Innovation Management; Lean Management; Change Management; Information Distribution; Information Integration;

    Sammanfattning : ABB Corporation is a swedish-swiss international company, specializing in power and automation technologies. The company is a joint-venture between ASEA and Brown Bouveri, merging into one company in 1988. ABB has five business unit, where the products and services mainly comes from research and development work within the company. LÄS MER

  7. 5. Characterization of the global Brown Swiss cattle population structure

    Master-uppsats, SLU/Dept. of Animal Breeding and Genetics

    Författare :Worede Gebremariam; [2010]
    Nyckelord :Inbreeding; population size; founder; ancestor; Brown Swiss;

    Sammanfattning : The global Brown Swiss population was studied to estimate population genetic parameters, measure genetic variation and identify most influential animals. The population was found to have 3.30 mean equivalent complete generations. The mean inbreeding coefficient was 0. LÄS MER
