Vlivy působící na množství somatických buněk v mléce holštýnských krav ve vybraném chovu

The aim of this thesis was to assess and evaluate various influences on somatic cell count of Holstein cows milk in a selected dairy farm. Five years (2012-2016) of monitoring animal recordings was used as a basis for studying and finding indicators that affect of somatic cells count. Milk yield, fat and protein content were also analyzed from data taken from animal recordings. We studied effects of the month, the year, the number of lactation and the milk yield. Mean values and other statistical indicators of milk compounds (minimum, maximum, coefficiet of variation, standard deviation) were determined and then compared with the other months and years. The results show that milk yield, number of lactation, month of the year effects somatic cell count. Weak correlation was found for influence the fat and protein content on somatic cell count
