In this bachelor thesis the analysis of milk yield of Czech fleckvieh cattle in selected breeding was performed, with regard to external and internal influences affecting milk production. The monitoring was carried out for 12 months, in the period from 01/2019 to 12/2019 in the stable Lubník, which belongs to the agriculture company ZOD Žichlínek and result from milk recording scheme. The monitoring was focused on fluctuations in milk production and milk elements, especially fat and protein, depending on individual seasons, the order and phase of lactation. Based on the results, we can conclude that the highest milk yields were achieved by cows at the 4th and higher lactation, dairy cows with a lactation phase of up to 100 days and in the spring period. The highest fat and protein content in milk was found in dairy cows with a lactation phase above 301 days.
