1. 1. Evaluation of liver and fur copper concentrations in dairy cows : in relation to dietary intake of copper and molybdenum

   Master-uppsats, SLU/Dept. of Animal Nutrition and Management

   Författare :Ida Hansen; [2023]
   Nyckelord :copper; copper status; dairy cow; fur; liver; molybdenum; ruminant;

   Sammanfattning : Koppar (Cu) har en avgörande roll i flera viktiga metaboliska funktioner och är en essentiell mineral för idisslare. Kopparbrist kan resultera i ett flertal problem som påverkar djurets hälsa och produktion, men även överutfodring av Cu kan resultera i allvarliga kliniska symptom på grund av ackumulering av Cu i levern.
