  1. 1. Free faecal liquid in horses : associations with nutritional factors

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

    Författare :Elena Rönnqvist; [2020]
    Nyckelord :concentrates; feeding; feed ration; forage; gastrointestinal tract; haylage;

    Sammanfattning : The occurrence of free faecal liquid (FFL) in horses is a problem as it leads to contamination of the tail and inside of hindlegs, which may result in skin lesions. Distinct from diarrhoea, horses with this condition often defecate normal faeces, but also void faecal liquid before, during or after defecation of solid faeces. LÄS MER

  2. 2. The digesta passage rate among dairy cows with different abilities to consume large quantities of roughage : its impact on the milk production, and the reliability of the chemical fibre marker

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

    Författare :Maria Elisabeth Eklund; [2020]
    Nyckelord :chemical markers; chromium; chromium mordanted fibre; cobalt; concen-trate level; EDTA; iNDF; mean re-tention time; ethylenediaminetetraacetic acid; forage consumption; indigestible neutral detergent fibre; liquid digesta phase; MRT; rumen evacuation; sol;

    Sammanfattning : The objectives of the present master thesis were to investigate the passage rate among lactating Holstein and Swedish red dairy cows to investigate the hypotheses of: 1) The cows’ individual total mean retention time (TMRT) has a negative relationship to the cows’ individual forage intake capacity. 2) A reduced TMRT contributes to a reduced feed efficiency, but a higher milk yield.

  3. 3. Heterologous expression and purification of Nicotiana benthamiana Cellulose synthase-like B (NbCslB)

    Master-uppsats, KTH/Skolan för kemi, bioteknologi och hälsa (CBH)

    Författare :Olivia Ståhl; [2020]
    Nyckelord :Biotechnology; Cellulose Synthase-Like B; Glycoscience; Glycosyltransferase; Hemicellulose; Nicotiana benthamiana; Bioteknik; Cellulosasyntasliknande B; Glykosyltransferas; Glykovetenskap; Hemicellulosa; Nicotiana benthamiana;

    Sammanfattning : Hemicelluloses are synthesized by proteins encoded by genes from the cellulose synthasegene superfamily. One subgroup of this gene family is the cellulose synthase-like B, which islargely uncharacterized and unexplored. The common model organism Nicotianabenthamiana has one such gene in its genome, NbCslB, encoding a membrane protein. LÄS MER

  4. 4. Field study of the drought’s impact on feeding strategy and biological parameters in early lactation dairy cattle

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

    Författare :Mikaela Würtz; [2019]
    Nyckelord :dairy cattle; drought; energy balance; feeding; metabolism;

    Sammanfattning : The summer of 2018 was unusually warm and dry. For animal production, this resulted in poor pastures, reduced harvests of crops, such as roughage and grains, and increased risk for heat stress in the animals. The drought led to problems as in shortage of animal feed, which made the feeding of dairy cattle difficult. LÄS MER

  5. 5. UTVÄRDERING AV DNA-EXTRAKTIONSPROTOKOLL FÖR FORENSISKA PROVER

    Kandidat-uppsats, Malmö universitet/Hälsa och samhälle

    Författare :Kassem Awad; [2019]
    Nyckelord :Autolys A rör; Chelex resin; Detergent; DNA-extraktion; qPCR; Saliv; Spårsäkring; Tops;

    Sammanfattning : Vid låga mängder av DNA, vilket det ofta är vid forensiska prover, är en lyckad DNA-analys beroende av ett effektivt DNA-extraktionsprotokoll. Bland flera kommersiellt tillgängliga extraktionsmetoder för DNA har tidigare studier visat att Chelex 100 resin, som idag används på Nationellt Forensiskt Centrum i Linköping, är en snabb och enkel metod utan toxiska ämnen, långa väntetider eller större kostnader och som även ger ett högt DNA-utbyte.
