1. Domestic protein feeds in dairy production : potential of rapeseed feeds and red clover
Sammanfattning : 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. LÄS MER
2. Livestock, feed production and land use – an environmental assessment
Sammanfattning : 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. LÄS MER
3. Fibrous feeds for functional fowls
Sammanfattning : 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.

4. Hempseed cake as a protein feed for ruminants
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
5. Thermostable Phytase from a Bacillus sp.: Heterologous Production, Mutation, Characterization and Assay Development
Sammanfattning : 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. LÄS MER
