  1. 1. Analysis of relatedness and genetic diversity in Swedish sheep breeds using medium density (50K) SNP data

    University essay from SLU/Dept. of Animal Breeding and Genetics

    Author : Krishani Devika Wijesinghe Sinhalage; [2023]
    Keywords : sheep; genetic diversity; population structure; inbreeding; runs of homozygosity; coat colour; MC1R;

    Abstract : The local Swedish sheep breeds belong to a group of sheep breeds known as North European short-tailed sheep breeds. Evaluation of genetic diversity, relatedness, and population structure of local breeds offers crucial metrics to prevent inbreeding depression, genetic erosion, and crossbreeding between locally adapted and exotic sheep breeds since these occurrences can have detrimental effects and ultimately lead to extinction.

  3. 2. Analys av startstatus hos varmblodiga ridhästar

    University essay from SLU/Dept. of Animal Breeding and Genetics

    Author : Ylva Blom; [2023]
    Keywords : SWB; startstatus; arvbarheter; genetiska korrelationer;

    Abstract : Avelsmålet för den svenska varmblodiga ridhästen, SWB, är att producera ”en ädel, korrekt och hållbar varmblodshäst som genom sitt prestationsinriktade temperament, sin ridbarhet, goda rörelse- och/eller hoppförmåga är internationellt konkurrenskraftig”. I avelsvärderingen för SWB används idag resultat från unghästbedömning samt livstids ackumulerade poäng från tävling. READ MORE

  4. 3. Evaluation of the impact of mitochondrial variation in the estimation of breeding values for dairy cattle

    University essay from SLU/Dept. of Animal Breeding and Genetics

    Author : Gabriela Mafra Fortuna; [2021]
    Keywords : mitogenome; variance components; milk yield; simulation;

    Abstract : Mitochondria are independent cellular components responsible for cellular respiration. Through oxidative phosphorylation they convert Adenosine diphosphate and inorganic phosphate into Adenosine Triphosphate, ATP, the essential molecule sourced by all intracellular metabolic processes.

  5. 4. Changes in habitat suitability for three declining Anatidae species saltmarshes on the Mersey estuary, North-West England

    University essay from Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

    Author : Cecilia Baggini; [2020]
    Keywords : Geography; GIS; habitat suitability model; saltmarsh; protected areas; Earth and Environmental Sciences;

    Abstract : Saltmarshes are areas of coastal grassland that are regularly flooded by seawater. They support a large number of resident and migratory bird species, both overwintering and breeding. READ MORE

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

    University essay from SLU/Dept. of Animal Breeding and Genetics

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

    Abstract : 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.
