  1. 1. Fenotypisk karaktärisering av 375 brakycefala hundar i Sverige

    Uppsats för yrkesexamina på avancerad nivå, SLU/Dept. of Clinical Sciences

    Författare :Sara Sahlin; [2021]
    Nyckelord :BOAS; brakycefal; trubbnos; fenotyp; fenotypisk variation; riskfaktorer; mops; fransk bulldogg; engelsk bulldogg; old English bulldogg; bostonterrier;

    Sammanfattning : De brakycefala hundraserna har blivit alltmer populära i världen och aveln har därför ökat. Hundarna ser inte längre ut som de gjorde från början och kännetecknas framförallt av deras korta skalle. LÄS MER

  3. 2. Evaluation of in vitro antagonism assays in the mycoparasitic fungus Clonostachys rosea

    Kandidat-uppsats, SLU/Dept. of Forest Mycology and Plant Pathology

    Författare :Victor Olsson; [2020]
    Nyckelord :Biocontrol; Biocontrol agent; Clonostachys rosea; Fusarium gramine-arum;

    Sammanfattning : Fungicide use is the dominant direct method to control fungal pathogens on crops in agriculture. While effective, excessive use of them can be harmful to biodiversity and lead to fungicide resistance in pathogen populations. Biocontrol is an alternative where natural antagonistic organisms, called biocontrol agents (BCA), are used to protect crops. LÄS MER

  4. 3. Phenotypic variation for BOAS within four brachycephalic dog breeds : can good welfare be obtained?

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

    Författare :Ida Bertilsson; [2019]
    Nyckelord :BOAS; French bulldog; English bulldog; Pug; Boston Terrier; Conformation; welfare; phenotypic variation; respiration; brachycephaly; dog;

    Sammanfattning : Brachycephalic obstructive airway syndrome (BOAS) is an upper airway obstruction that was considered the most severe disorder identified according to the Generic Illness Severity Index for Dogs. The aim of this master thesis was to investigate the phenotypic variance correlated to BOAS in the Swedish population of four brachycephalic breeds; English Bulldog, French Bulldog, Pug and Boston Terrier and discuss their welfare implications.

  5. 4. 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

  7. 5. Genotypic and phenotypic variation of Phytopthora infestans on potato in the two Swedish regions Bjäre and Östergötland in 2015

    Master-uppsats, SLU/Dept. of Forest Mycology and Plant Pathology

    Författare :Ida Peterson; [2015]
    Nyckelord :potato late blight; mating type; simple sequence repeat markers SSR ; microsatellites; Multiplex PCR; sexual reproduction; asexual reproduction; aggressiveness; tests; population study;

    Sammanfattning : Potato late blight, caused by the oomycete Phytophthora infestans, is a very im-portant disease on potato, and one of the most devastating plant diseases in agri-culture worldwide. Despite the small area of potato in comparison with other cul-tivated crops, 40 % of the total use of fungicides in Sweden is used on potato. LÄS MER
