  1. 1. Dystocia in Swedish beef cattle : effects of different scoring systems on the genetic evaluation

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

    Författare :Filip Nilsson; [2019]
    Nyckelord :Swedish beef cattle; residuals; genetic evaluation; normal score; beef breeding;

    Sammanfattning : In Swedish beef cattle breeding, the genetic evaluation comprises calving traits, carcass traits and growth traits. For the calving traits stillbirth, birth weight and dystocia severity grade are recorded. LÄS MER

  3. 2. Calving ease and stillbirth in dairy herds using beef and dairy breed bulls

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

    Författare :Patricia Gullstrand; [2017]
    Nyckelord :crossbreeding; dairy; beef; calving ease; stillbirth;

    Sammanfattning : The aim of this study was to evaluate the effect of different sire breeds on calving traits when used in dairy herds. Records from 1,423,851 calvings from 1990-2016 were collected from the Swedish milk recording scheme from Swedish Holstein, Red dairy cattle, Hereford, Charolais, Aberdeen Angus, Limousin and Simmental sires mated with Swedish Holstein, Red dairy cattle or crossbred dams.

  4. 3. Preference for breeding goal traits among Swedish and Norwegian dairy farmers : associations between preference and herd characteristics

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

    Författare :Torgunn Aslaug Skjerve; [2017]
    Nyckelord :farmer’s preference; dairy cow; breeding goal;

    Sammanfattning : The aim of this study was to investigate similarities and differences among Norwegian and Swedish dairy farmers’ preference for breeding goal traits, and compare systematic effects within each country. The specific objectives were to analyse variation in ranking among farmers, and derivate relevant clusters using cluster analysis. LÄS MER

  5. 4. Effects of three colostrum-feeding methods on the behaviour and management of dairy calves

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

    Författare :Ida Lundmark; [2016]
    Nyckelord :management; behaviour; suckling; bottle; oesophageal tube;

    Sammanfattning : Saving time and money are always important considerations in the agricultural sector and in dairy farming the calves’ management plays a central role. One of the most important aspects of rearing calves is the colostrum-feeding routines and several studies have come to the same conclusion that the volume fed, quality of milk fed and when the calves are fed after parturition, are the three most important aspects.

  7. 5. Kalvningssvårigheter och dödfödslar hos SH och SRB

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

    Författare :Karin von Schlanbusch; [2016]
    Nyckelord :kalvningssvårigheter; dödfödslar; foder; skötsel; calving difficulty; stillbirth; forage; management;

    Sammanfattning : Over the past three decades, calf mortality has increased in Swedish Red and Swedish Holstein dairy cows. This is mainly due to the use of imported semen from Holstein bulls from US which has generated bigger calves and because of this, calving difficulty has increased. LÄS MER
