    Nyckelord :betesgrödor; gotlandsfår; slaktvikt; tillskottsutfodring; vinterlamm;

    Sammanfattning : Gotlandsfåren som har en aktiv avelspopulation om 18 000 tackor är Sveriges van-ligaste fårras. Med en stark säsongsbunden brunst på hösten föds lammen under våren och slaktas traditionellt sätt på hösten efter betessäsongen. LÄS MER

  3. 17. The effect of temperature on productivity of birds in Sweden and Finland

    Kandidat-uppsats, Linköpings universitet/Biologi

    Författare :Johanna Orsholm; [2019]
    Nyckelord :Birth rate; Global warming; Reproductive success; Species traits; Climatic niche; Multiple breeding; Breeding success;

    Sammanfattning : Anthropogenic climate change is one of the most important factors influencing population growth and survival. Therefore, to be able to predict the effect of climate change on ecosystem composition and function, it is important to understand its effect on demographic variables, such as productivity. LÄS MER

  4. 18. Is it possible to improve the bovine immune response to mastitis using immunogenetics?

    Kandidat-uppsats, SLU/Dept. of Biomedical Sciences and Veterinary Public Health

    Författare :Emelie Björnhagen; [2019]
    Nyckelord :bovine; immunology; genetics; breeding; mastitis;

    Sammanfattning : Mastitis is a major problem for cows all over the world. For decades selection against mastitis has been performed through direct and indirect selection. Favorable outcomes of reduced mastitis incidence include: Economic gains, reduced use of antibiotics as well as improved animal welfare. LÄS MER

  5. 19. Why are you not breeding? : a study on the reproductive success of captive wolverines (Gulo g. gulo)

    Master-uppsats, SLU/Dept. of Animal Environment and Health

    Författare :María Slof Pacilio; [2019]
    Nyckelord :breeding success; wolverine; reproduction; zoo; animal welfare; behavior; enrichment; training; zookeepers;

    Sammanfattning : Conservation biologists have long faced the very challenging task of large carnivore conservation. Both their hunting habits and their very specific ecology make their conservation particularly difficult. Wolverines (Gulo g. gulo) are a good example of this. LÄS MER

  7. 20. Mellanspettens förutsättningar för återintroduktion i Linköping : Med fokus på krav på kvalitet och storlek samt avstånd mellan habitat.

    Kandidat-uppsats, Linköpings universitet/Biologi

    Författare :Rebecca Petersen; [2019]
    Nyckelord :Dendrocopos medius; reproductive success; habitat selection; oak forest; restoration.;

    Sammanfattning : Humans have a large impact on biodiversity, especially by causing habitat loss and habitat degradation but also through human-induced climate change. Because of habitat loss and habitat degradation the Middle-spotted woodpecker (Dendrocopos medius) went extinct in Sweden 1983. LÄS MER
