1. Valorization of herring filleting co-products to silage - Control of protein hydrolysis and lipid oxidation during ensilaging and possibilities for separating herring silage into multiple products
Abstract : Industrial processing of herring ( Clupea harengus ) into convenience products such as fillets generates around 60% co-products being rich in both protein and n-3 polyunsaturated fatty acids (PUFAs). A promising cost-efficient strategy to valorize these raw materials into food and/or feed ingredients would be to apply ensilaging, i.e. READ MORE

2. Improved utilisation of grass silage in milk production : harvesting strategy and feeding value
Abstract : The aim of the studies reported in this thesis was to optimise grass silage utilisation in milk production. In the first paper of this thesis data from digestibility trials with sheep fed at maintenance level were used to investigate the effect of forage type and harvesting time of silage on energy and N metabolism.

3. Methods to study the relationship between forage composition and silage fermentation and aerobic stability
Abstract : This thesis is based on the following hypotheses: (I) under controlled ensiling conditions, forage chemical and microbial composition explain variation in silage end-product concentrations (II) sterilized forage inoculated with parent microflora gives similar fermentation result as untreated control forage and (III) this methodology enables studying interactions between forage source and field flora on silage fermentation and aerobic stability. Hypothesis (I) was evaluated by constructing regression models of end-products on common forage chemical variables (e. READ MORE

4. Effects of increasing the proportion of high-quality grass silage in the diet of dairy cows
Abstract : The Swedish dairy cow has almost doubled its annual milk yield over a few decades. This has simultaneously led to an increase in the dietary proportion of concentrate in order to meet the increased nutritional requirement of dairy cows. READ MORE

5. Ley crop silage in diets to fattening pigs : How does it affect pig performance, nitrogen utilization, health and behaviour?
Abstract : There is an increasing interest to use silage as a feed ingredient to pigs. The aim of this thesis was to study the effect of using silage in the diet to fattening pigs and how feeding strategy influenced pig performance, behaviour, gut health and nitrogen utilization. Two studies were performed. READ MORE
