Změny v chemickém složení syrového kravského mléka v průběhu roku / Changes in chemical composition of raw cow´s milk during a year

The aim of thesis was to analyze results of raw bulk milk according to these quality indicators: fat content, protein content, urea content, casein content, solids-not-fat (SNF) content, lactose content and freezing point. Data were evaluated from November 2009 through October 2010 at two breedings. Limits given by European Union and czech legislation were keep in both breedings. In first breeding were mediumly means 4,127 g/100g fat, 3,427 g/100g protein, 2,601 mmol/l urea, 2,688 g/100g casein, 9,015 g/100g solids-not-fat, 4,887 g/100g lactose and freezing point -0,5265 °C.In second breeding were mediumly means 4,045 g/100g fat, 3,319 g/100g protein, 2,462 mmol/l urea, 2,603 g/100g casein, , 8,839 g/100g solids-not-fat, 4,828 g/100g lactose and freezing point -0,5246 °C. Results were compared and causes of difference and milk quality variation were explained.
