    Author : Jhon William Perez Davila; [2023]
    Keywords : protein digestibility; amino acids; ley crops; silage; biorefinery; press juice; growing pigs;

    Abstract : The study aimed to evaluate the protein and amino acid digestibility of press juice from biorefined ley crops in the form of fresh (FPJ) and silage (SPJ) when included as an ingredient in liquid diets for pigs. The juice was extruded from ley crops mixture (grass-clover). READ MORE

  5. 24. Separation and acidification of digested animal manure : properties of the future organic fertilizers

    University essay from SLU/Dept. of Soil and Environment

    Author : Marie Björs; [2023]
    Keywords : Digestate; Eutrophication; Farmers’ survey; Plasma activation; Screw press;

    Abstract : Agricultural areas with a high animal density contribute to eutrophication in waterbodies and seas worldwide due to accumulation of nutrients around animal farms. Animal manure is heavy and bulky, thus unpractical to transport long distances and new techniques have been developed to refine animal manure and make it easier to transport. READ MORE

  6. 25. Vad kännetecknar ett lämpligt foder för unga kastrerade katter? : foderval med fokus på den växande individen

    University essay from SLU/Dept. of Clinical Sciences
