  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. Gonadal hypoplasia in Swedish Mountain cattle and other native Swedish cattle breeds

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

    Author : Julia Hinken; [2023]
    Keywords : gonadal hypoplasia; Swedish Mountain cattle; fjäll;

    Abstract : The Swedish Mountain cattle and several related breeds show the phenotype of colour-sidedness. The genetic reasons for this phenotype are a translocation and duplication from chr6 to chr29 (known as Cs29) including the KIT gene and an additional translocation with part of the Cs29 translocation from chr29 back to chr6 (Cs6).

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

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

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

    Abstract : 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.

  5. 4. Plasmin and plasminogen variation in bovine raw milk : impact of season, breed and milking system

    University essay from SLU/Department of Molecular Sciences

    Author : Jaafar Khaled; [2019]
    Keywords : Plasmin; season; breed; milking system; milk composition; plasminogen;

    Abstract : Plasmin (PL) is a native proteinase in milk, which combines a complex system consisting of its zymogen called plasminogen (PG), inhibitors and activators, which activity is known to make considerable changes in the dairy products, which represent in irregulating of casein hydrolysis and poor clotting properties, that may slow the cheese ripening process and consequently increase the processing expense. The objective of this study was to investigate if on-farm factors (i. READ MORE

  6. 5. Embryotransfer : en framtid för svensk fårnäring?

    University essay from SLU/Dept. of Animal Environment and Health

    Author : Elinor Asp Tauni; [2017]
    Keywords : embryotransfer; MOET; får; Sverige; import;

    Abstract : Embryotransfer innebär att ett embryo överförs från en donator till en mottagare. Denna teknik gör att man kan öka antalet avkommor från ett moderdjur och vid import kan transporten av levande djur undvikas och ett högre smittskydd nås. READ MORE
