  1. 1. Estimating the effective population size of Swedish native cattle : understanding the demographic trajectories of indigenous Swedish cattle breeds

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

    Författare :Dolapo Adepoju; [2022]
    Nyckelord :Swedish native cattle; effective population size; genetic drift; cattle demographic trajectories; native cattle conservation;

    Sammanfattning : The indigenous cattle populations are on the decline globally with the continuous improvement of genetic gains in commercial breeds. Due to their unique adaptive features to the local ecosystem, traditional cattle breeds are pools of valuable genetic resources that could help combat the impact of climate change in the near future.

    Sammanfattning : Profitable dairy production is always strived for. In recent years, dairy production in developed countries struggle with genetic problems like increasing inbreeding, reduced fertility and at the same time increasing market demands for competitiveness. LÄS MER

  5. 4. Hornlöshet hos kött- och mjölkkor: nedärvning och samband med andra egenskaper

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

    Författare :Elin Dalemar; [2015]
    Nyckelord :hornlöshet; kullig; horn; nötkreatur; mjölkkor; köttdjur; genetiska samband; avhorning;

    Sammanfattning : I denna litteraturstudie sammanfattas information angående hornlöshet hos kött- och mjölkkor. Syftet omfattar att undersöka hur fenotypen nedärvs, om det finns skillnader mellan raser samt att redovisa samband med andra egenskaper. Kor med horn kan orsaka skador på såväl djur som människor och korna blir därför svårare att hantera. LÄS MER

  7. 5. Cross-sectional study of the prevalence of Babesia bigemina in Uganda : wildlife-livestock interface at and around LMNP

    Uppsats för yrkesexamina på avancerad nivå, SLU/Dept. of Biomedical Sciences and Veterinary Public Health

    Författare :Anna Schischke; [2015]
    Nyckelord :Babesia bigemina; wildlife-livestock interface; cattle; Uganda; vilda djur; nötkreatur;

    Sammanfattning : Ticks and the diseases they transmit are of major importance throughout the world. In Uganda, cattle are the most important livestock from an economic point of view. Livestock keepers fear bi-directional transmission of tick-borne pathogens between their livestock and wild animals. LÄS MER
