  1. 1. Feeding Live or Dried Black Soldier Fly Larvae (Hermetia illucens) to laying hens – Effects on Immune Traits, Egg Quality, Feather Condition, Body and Organ Weights

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

    Författare :Adnan Aslam; [2023]
    Nyckelord :Black soldier fly; live larvae; dried larvae; immune response; egg quality; body weight; feather condition scoring;

    Sammanfattning : Due to increasing prices and potential scarcity of soybean meal (SBM), there is growing demand for alternative and sustainable protein sources in poultry production. Black soldier fly larvae (BSFL) have proven to be a suitable alternative based on nutritional value and sustainable production. LÄS MER

  3. 2. Biocatalysis in Pickering emulsions

    Master-uppsats, Lunds universitet/Bioteknik (master); Lunds universitet/Bioteknik (CI)

    Författare :Christine Vera Isabel Schmidt; [2023]
    Nyckelord :Enzymes; Pickering emulsion; Amine Transaminases; Green Chemistry; Stereoselectivity; Biotechnology; Biology and Life Sciences;

    Sammanfattning : Employing enzymes as catalysts in the production of chiral amines that are both used as building blocks and active pharmaceutical ingredients might be promising due to milder reaction conditions compared to non-biological catalysts, exclusion of heavy metals, high selectivity towards substrates and precision in chirality of the products. Transaminases are attractive for the use in this process. LÄS MER

  4. 3. Kokta äggs hållbarhet i rumstemperatur. : Studie av lipidoxidation och mikrobiell förekomst.

    Kandidat-uppsats, Linnéuniversitetet/Institutionen för kemi och biomedicin (KOB)

    Författare :Cecilia Carlegård; [2023]
    Nyckelord :egg; lipidoxidation; thiobarbituric acid; TBARS; ägg; lipidoxidation; tiobarbitursyra; TBARS;

    Sammanfattning : Eggs are a popular food widely consumed worldwide, due to their nutrient density and shelf life even at room temperature. This study aimed to investigate if eggs keep better in the refrigerator than at room temperature post-boiling. LÄS MER

  5. 4. Novel Scale Chemistry of Salmo Salar L. : New Linkage of Otolith and Scale Chemistry to M74 Reproductive Disorder

    Master-uppsats, Uppsala universitet/Institutionen för medicinsk biokemi och mikrobiologi

    Författare :Michelle Von Ehr; [2022]
    Nyckelord :Thiamine; M74; Salmon; Otolith chemistry; Scale chemistry; laser-ablation coupled inductively plasma mass spectrometry;

    Sammanfattning : Baltic salmon suffer from maternally transmitted M74 reproductive disorder, which causes yolk-sac fry mortality due to thiamine deficiency. This study investigates trace elemental analyses of Baltic salmon applied on otoliths and scales and their possible link to identifying M74. LÄS MER

  7. 5. Effects of melatonin and Single Layer Centrifugation on cryosurvival of ram semen samples

    Master-uppsats, SLU/Dept. of Clinical Sciences

    Författare :Lea Enenkelová; [2021]
    Nyckelord :sheep reproduction; Jezersko-Solčava sheep breed; colloid centrifugation; melatonin;

    Sammanfattning : The composition of the ram sperm membrane renders it vulnerable to injury during cryopreservation. Production of reactive oxygen species, which are by-products of metabolism, increases during freezing and thawing, causing damage to sperm membranes and acrosomes as well as affecting mitochondrial activity.
