1. 1. 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%).

3. 2. 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

4. 3. 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.
