  1. 1. Detection and Characterisation of Salmonella in Animal Feed Samples by PCR-Based Methods

    Författare :Charlotta Löfström; Teknisk mikrobiologi; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Food and drink technology; Livsmedelsteknik; Biotechnology; Bioteknik; Biokemisk teknik; Biochemical technology; Analytisk kemi; Analytical chemistry; mykologi; virologi; bakteriologi; Mikrobiologi; validation; Microbiology; bacteriology; virology; mycology; Salmonella; ribotyping; detection; animal feed; randomly amplified polymorphic DNA; pulsed-field gel electrophorsis; pre-PCR processing; PCR; polymerase chain reaction; genotyping;

    Sammanfattning : Animal feed is a recognised source of Salmonella enterica for farm livestock and may also indirectly cause infection in people consuming foods of animal origin. It is therefore important to have rapid, reproducible and specific methods for the detection of Salmonella in feed, and for the characterisation of strains for further epidemiological investigations or to trace the source of contamination in a production facility.

  2. 2. Groundnut foliage as feed for Cambodian cattle

    Författare :Pok Samkol; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Nyckelord :LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES;

    Sammanfattning : This thesis explored smallholder cattle production in Cambodia and investigated the nutritive value of groundnut (Arachis hypogaea L.) foliage and/or cassava (Manihot esculenta, Crantz) tops as protein supplementation for cattle production. LÄS MER

  3. 3. Zygomycetes and cellulose residuals : hydrolysis, cultivation and applications

    Författare :Patrik Lennartsson; Patrik R Lennartsson; Högskolan i Borås; []
    Nyckelord :ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; zygomycetes; fungi; lignocelluloses; ethanol; fish feed; animal feed; dimorphism; airlift; pretreatment; Biotechnology; Resursåtervinning; Resource Recovery; Zygomycetes;

    Sammanfattning : Zygomycetes is a class of fungi living worldwide as saprobes, as part of mycorrhizae, and as parasites. Humans have used some zygomycetes for centuries in the production of traditional foods, e.g. Indonesian tempe. LÄS MER

  4. 4. Nutrient utilisation in growing Cambodian cattle : effect of different feed sources and feed conservation techniques

    Författare :Keo Sath; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Nyckelord :LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES;

    Sammanfattning : Natural forages are an important part of the diet of cattle in Cambodia, but their nutrient value, particularly in terms of macro-minerals, may be inadequate, leading to potential mineral deficiencies in grazing cattle. This thesis compared the nutrient composition of six forage types (rice bran, rice straw, para grass, cassava foliage, leucaena leaves, water hyacinth leaves) from two regions in Cambodia against faecal and urinary excretion of macro minerals by cattle.

  5. 5. Hempseed cake as a protein feed for ruminants

    Författare :Linda Karlsson; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Nyckelord :LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES;

    Sammanfattning : Increasing the use of locally produced protein feeds in ruminant production systems in northern Europe would be a valuable development. Hemp (Cannabis sativa L.) can be cultivated at high latitudes and cold-pressing the seeds to extract the oil produces a residue, hempseed cake (HC), with a high protein content. LÄS MER
