BOUCHALOVÁ, Jana
The aim of this thesis was to enumerate the contents of important trace elements in cow's milk (iodine, zinc, copper, manganese) and evaluate the importance of milk as the natural resources in human nutrition. The average content of iodine in cows' milk in farms of South Bohemia in 2009 was 360,91 ?g/l, 2010 440,62 ?g/l in 2011 337,14 ?g/l. The average content of zinc in cow's milk in 2009 was 4825,15 ?g/l. The average content of copper in cow's milk in 2009 was 38,78 ?g/l. The average content of manganese in cow's milk in 2009 was 16,49 ?g/l. The average consumption of 0.16 liter of milk per person per day provided income of iodine in 2009 in 39%, in 2010 in 47%, in 2011 in 54%, income of zinc in 2009 in 6%, copper income in 0,3% and manganese income in 0,07%.
