    Författare :Erik Backman; [2021]
    Nyckelord :kalv; tillväxt; hull; juverparenkym;

    Sammanfattning : I den här studien undersöktes kalvar som tilläts dia fritt från sina mammor, avseende hullutveckling och tillväxt av juverparenkym under den första månaden i livet. Detta eftersom det finns en oro att kalvar som får dia fritt blir överviktiga. LÄS MER

  3. 2. Sow and piglet behaviour and weight: implications of different ages of weaning : a study within Swedish piglet production

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

    Författare :Rebecka Brattlund Hellgren; [2021]
    Nyckelord :piglet; sow; weaning age; behaviour; growth;

    Sammanfattning : Natural weaning of piglets occurs gradually and finalises between 14-17 weeks of age.

  4. 3. Factors influencing variation in birth weight and its impact on later performance in Swedish Yorkshire pigs

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

    Författare :Paulina Wahlgren; [2018]
    Nyckelord :Piglets; birth weight; field performance test; backfat thickness; growth performance;

    Sammanfattning : The phenotypic variation in piglet birth weight caused by gender, birth parity number and litter size, and later how this variation in birth weight influenced growth rate until 100 kg and backfat thickness at 100 kg live weight were analysed in this study. Data on purebred Swedish Yorkshire pigs from 13 nucleus herds was the base for the analyses. LÄS MER

  5. 4. Automatic Body Condition Scoring on Dairy Cows of the Swedish red breed

    Master-uppsats, SLU/Dept. of Animal Nutrition and Management
