  2. 1. Domestic protein feeds in dairy production : potential of rapeseed feeds and red clover

    Author : Helena Gidlund; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Keywords : LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES;

    Abstract : The purpose of the four studies that form the basis for this thesis was to extend the knowledge about how to utilize the domestic protein feeds in Swedish dairy production. To optimize the use of nitrogen (N) from both concentrates and forages into milk product, and thereby improving the profitability and the resilience of the domestic dairy farms. READ MORE

  4. 2. Livestock, feed production and land use – an environmental assessment

    Author : Yaw Sasu-Boakye; Chalmers tekniska högskola; []
    Keywords : LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; partial equilibrium modelling; land use impacts; livestock production; soya beans; life cycle assessments; ecosystem services; protein feeds; feed substitution;

    Abstract : The use of land for agriculture contributes substantially to today’s global environmental challenges such as climate change, water and land degradation and biodiversity loss. Today, about 38% of the ice-free land surface on earth is used as agricultural land, with about 75% of agricultural land used to produce feed for livestock. READ MORE

  5. 3. Fibrous feeds for functional fowls

    Author : Robin Kalmendal; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Keywords : LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES;

    Abstract : Fibres are not digested by fowls, but their impact on digestive physiology, nutrient metabolism and intestinal microflora can be substantial. Analytical shortcomings have historically contributed to different notions on the significance of fibres, but modern techniques now enable us to better discriminate between various fractions of fibre and relate them with the performance of poultry.

  6. 4. Hempseed cake as a protein feed for ruminants

    Author : Linda Karlsson; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Keywords : LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES;

    Abstract : 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. READ MORE

  7. 5. Thermostable Phytase from a Bacillus sp.: Heterologous Production, Mutation, Characterization and Assay Development

    Author : Tran Thi Thuy; Bioteknik; []
    Keywords : ß-propeller phytase; recombinant protein; site-directed mutagenesis; phytate;

    Abstract : Phytase is an important enzyme in the food/feed industry. It catalyzes the hydrolysis of phytate, an anti-nutrient compound present in cereals and grains, to release orthophosphate and myo-inositol-6-phosphate with lower degrees of phosphorylation. READ MORE
