  3. 27. Teknisk pelletkvalité och foderförlust av fiskfoder gjort på biprodukter från fisk

    University essay from SLU/Dept. of Animal Nutrition and Management

    Author : Jenny Dahlberg; [2020]
    Keywords : teknisk pelletkvalité; pellethårdhet; pellethållbarhet; pelletdensitet; biprodukter; fiskensilage; foderförlust;

    Abstract : Sverige får årligen omkring 20 000–60 000 ton biprodukter från den industriella bearbetningen av fisk och skaldjur. Syftet med denna studie är att analysera om biprodukternas tillsatts i fiskfoder har en påverkan på den tekniska pelletkvaliteten samt att dra slutsatser av fiskfodrets foderförlust kopplat till pellethållbarhet.

    Keywords : white rhino; post-fire regrowth; habitat selection; African grazers; megaherbivore;

    Abstract : The white rhino is a megaherbivore grazer that favours the short and nutrient-rich grass on grazing lawns. Since regrowth on lawns requires a certain amount of rainfall, the usage of this food resource is limited to the wet season. During the dry season, white rhinos are able to feed on senescent tall grass. READ MORE

  5. 29. Perfluorooctane sulfonate (PFOS) and related chemicals in eggs from Sweden and China

    Keywords : PFOS; PFOA; Chicken Egg; LC-MS MS; Organic egg; Conventional egg;

    Abstract : Dietary intake is one of the major routes of human exposure to perfluoroalkyl and/or polyfluoroalkyl substances (PFAS). The objective of this study was to measure perfluorooctane sulfonic acid (PFOS), perfluorooctanoic acid (PFOA) and perfluorohexane sulfonic acid (PFHxS) in organic and conventional egg from Sweden (n=8, consisted of 4 pooled eggs and 4 individuals) and China (n=9, consisted of 4 pooled eggs and 5 individuals) and compare the concentrations of PFAS between the two categories (organic and conventional).
