  1. 1. Utformning av spaltbevattning : kan det vara vägen mot renare grisar?

    University essay from SLU/Dept. of Biosystems and Technology (from 130101)

    Author : Cecilia Johansson; [2019]
    Keywords : spaltbevattning; droppbevattning; duschbevattning; djurvälfärd; boxhygien; slaktsvinstall;

    Abstract : Hygien i svenska slaktsvinsstallar och arbetsbelastningen under sommartid kan vara ett problem i Sverige på grund av att grisarna använder den fasta liggytan som gödselyta under sommartid. Att grisen försöker kyla sig när den utsätts för värmestress, hög beläggning, icke optimal utfodringsstrategi samt ökad produktivitet är faktorer som alla bidrar till dålig boxhygien. READ MORE

  3. 2. Ammoniakförluster vid flytgödselhantering : myllning och surgörning som metoder för att minska avgång vid spridning

    University essay from SLU/Dept. of Soil and Environment

    Author : Johannes Eriksson; Victor Olaison; [2014]
    Keywords : stallgödsel; ammoniakavgång; kväve; direktmyllning; svavelsyra;

    Abstract : The ammonia emissions are an environmental issue since they contribute to eutrophication. By far the largest source of ammonia emissions is manure from agriculture and should therefore be reduced. Loss of ammonia is not only negative for the environment but also to the farmer who loses nitrogen that could have been used by the crop. READ MORE

  4. 3. Investigation of a landfill leachate treatment plant in southern Sweden

    University essay from Lunds universitet/Examensarbeten i biologi

    Author : Alessandro Sarno; [2014]
    Keywords : nitrification; landfill leachate; on-site treatment; nitrogen mass balance; nitrogen removal; ammonia volatilization.; Biology and Life Sciences;

    Abstract : Dissolved ammonia is often referred to as one of the major contaminants in landfill leachates. Discharge concentration limits for municipal wastewater treatment plants in Sweden have been tightened in order to meet higher water quality standards. READ MORE

  5. 4. Mjölkureahalten som mått på vommikrobernas kväveförsörjning och kons miljöbelastning

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

    Author : Anna Strömgren; [2012]
    Keywords : mjölkurea; mjölkko; vommikrober; kväveförluster; fertilitet;

    Abstract : The aim of this literature study was to analyze how milk urea concentration is working as a measure of the nitrogen supply to rumen microbes and indicator of the environmental load. Questions included in this literature study were how to improve the dairy cattle nitrogen efficiency and what correlations there are between milk urea, nitrogen efficiency and crude protein content in the feed.
