Rozdíly v množství a složení mléka dojnic chovaných konvenčně a ekologicky
 Boubínová, Markéta
In thesis are comparing two cattle farms in area around Svratka, focussed on dairy cows of Czech Fleckvieh cattle. One is conventional farm and other is organic farm. Thesis is focused mainly on analysis of differences in volume of milk and its composition. Quantity of milk was monitored in monthly intervals for period of one year. Apart from milk quantity we observed contents of fat, protein and lactose. Number and day of lactation was also taken into account. Attention was given to composition of daily ration for dairy cows on organic farm, and we also monitored number of somatic cells and solids-non-fat in milk. It was found that dairy cows in organic farm breeding showed permanently lower performance of the animals, which was often statistically provable. Other factors differed depending on composition of daily ration and season. Content of fat and proteins had upward tendency in organic farm breeding. Amount of lactose differ only slightly between conventional and organic farms.
