  1. 1. Activity and stability of urease enzyme molecules for on-site urea measurement in milk

    University essay from Linköpings universitet/Sensor- och aktuatorsystem

    Author : Emma Valtersson; [2022]
    Keywords : Kemisk biologi; urea i mjölk; biosensor;

    Abstract : The nitrogenous metabolite urea is an important biomarker that indicates cows’ nutritional intake. Today, determining the urea concentration from milk samples requires analysis techniques in a lab which is time-consuming and expensive. READ MORE

  3. 2. Faktorer som påverkar proteinnedbrytning och kväveeffektivitet hos mjölkkor

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

    Author : Kajsa Ståhlberg; [2020]
    Keywords : protein; kväve; nedbrytning; utnyttjande; mikroorganismer; våmmen; urea; mjölkko;

    Abstract : Svenska mjölkkor utfodras idag med en stor andel protein för att upprätthålla en hög mjölkproduktion. Protein är ett viktigt näringsämne som bland annat stimulerar syntes av mjölk. För att säkerställa en hög mjölkavkastning finns det en risk att mjölkkon överutfodras med protein som inte kan utnyttjas. READ MORE

  4. 3. Milk production and protein utilization in high producing dairy cows fed a low CP diet based on cereals and roughage only : a full lactation study

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

    Author : Susanna Räisänen; [2016]
    Keywords : dairy cows; lactation; milk production; protein utilization; nitrogen efficiency; dietary protein level;

    Abstract : A feeding trial investigating the effect of a concentrate diet consisting only of cereals on milk production, protein utilization and nitrogen efficiency was conducted on Swedish dairy cows. 13 SRB and 12 SH cows were randomly assigned to one of two groups: group 1 was fed a concentrate feed (Cereal), mainly consisting of barley (36%), wheat (34%), oats (25%) as well as molasses (2%) and a mineral and vitamin mix (3%), whereas group 2 had access to both Cereal and a protein rich concentrate feed (Prot) based mainly on soya bean (51%) and rapeseed cake (28%).

  5. 4. Feed intake, in vivo digestibility and protein utilization of grass, red clover and maize silages in sheep

    University essay from SLU/Dept. of Animal Environment and Health

    Author : Elisabeth Saarsoo; [2015]
    Keywords : grass; maize; red clover; silage intake; digestibility; protein utilization; sheep;

    Abstract : Sheep in Sweden are usually fed grass/clover forage supplemented with concentrate during the winter season. Red clover forage fed to ruminants has shown to increase dry matter (DM) intake and give a lower in vivo DM digestibility compared to grass forage. READ MORE

  6. 5. Koncentrationer av mjölkurea, våmammoniak och urinurea vid olika halter av kalium i foderstaten till mjölkkor

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

    Author : Sara Johansson; [2014]
    Keywords : mjölkkor; mjölkurea; kalium; urinmängd; dricksvattenintag;

    Abstract : Analys av mjölkurea används idag som ett hjälpmedel i utfodringen till mjölkkor och kan användas för att övervaka kväveutsöndringen då det finns samband mellan kväveinnehållet i mjölk och urin. Sambandet mellan mjölkurea och urinurea kan påverkas av foderstatens sammansättning och egenskaper hos olika fodermedel. READ MORE
