  1. 1. Multi-environment Screening of Timothy (Phleum pratense) Breeding Material for Better Forage Yield in Sweden.

    Master-uppsats, SLU/Dept. of Plant Breeding (from 130101)

    Författare :Ibrahim Issa; [2022]
    Nyckelord :Phleum pratense; Multi-Environment; Forage yield; Sweden; Genotype-by-environment interaction Swedish;

    Sammanfattning : Timothy (Phleum pratense) is one of the most widely used forage crops in hay and pasture grass mixtures in Nordic countries; it’s also used in areas where it is one of the top forage crops harvested high yield, especially in boreal climates. There hasn’t been any large-scale breeding of Timothy to develop varieties that are adapted for Swedish climate and standards, which is surprising given that Timothy is the main forage crop used in Sweden.

  3. 2. Genotype by environment interactions of claw health in Swedish dairy cattle in tie stalls and loose-housing

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

    Författare :Hanna Johansson; [2012]
    Nyckelord :genotype by environment interactions GxE interactions ; genetic correlations; dairy cattle; claw health; claw disease; housing system; tie stalls; loose-housing;

    Sammanfattning : Claw diseases are common diseases in modern dairy production. They are painful for the cow and costly for the producer. Differences in the prevalence of claw disease depending on housing system have previously been observed. LÄS MER

  4. 3. Genotype by environment interaction for udder health in Swedish Holstein cows

    L3-uppsats, SLU/Dept. of Animal Breeding and Genetics

    Författare :Kristina Jansson; [2005]
    Nyckelord :genotype environment interaction; bovine mastitis; somatic cell count; dairy cows; quantitative genetics; genetic parameters;

    Sammanfattning : Genotype by environment interaction for somatic cell count and mastitis in the first lactation of the Swedish Holstein breed was studied, using a reaction norm model and multiple trait analysis. Data from the Swedish milk-recording scheme containing more than 200 000 cows having their first calving from 1995-01-01 and onwards was used. LÄS MER
