Quality assurance and its standardization of milk in automatic milking systems
 HRŮŠA, Jan
Thesis deals with the finding reliable measurement of the quality of milk by automatic milking system. The observed reliability of the system to measure the quality of milk is a significant parameter for herd management and also an effective tool for farmers. Thanks notice on udder health in the program T4C farmer is able to detect a number of health problems or deficiencies in the herd before they break out in full force. This gives the farmer more options to treat dairy cows, such as inflammation, at the very beginning and as such can successfully use homeopathic treatment.

Psychrotrophic lipolytic bacteria and content of free fatty acids in bulk samples of cow?s raw milk
 MIKULOVÁ, Magda
The objective of the study was to analyze the relationship of psychrotrophic lipolytic bacteria in bulk samples of cow?s raw milk and their metabolic activity based on the content of free fatty acids and identifying the factors that may influence their levels. The contents of free fatty acids (FFA) and counts of total bacteria, psychrotrophic lipolytic bacteria (PLiBC) and somatic cells were determined in 150 samples of cow?s bulk raw milk on 20 farms with three different milking technologies in South Bohemia during 2008?10. FFA were determined using an extraction-titration method. Within the compared technologies, the highest mean values of FFA (38,8 mmol?kg-1; P<0,001) and PLiBC (696 CFU?ml?1) were observed on farms with pipeline milking in stalls. The lowest mean FFA level (15,4 mmol?kg-1) was determined on farms with an automatic milking system. Medium values were determined on farms with parlour milking. From the aspect of the inhibition of an increase in psychrotrophic bacteria, and mainly in psychrotrophic lipolytic bacteria in conditions of cold storage of raw milk the temperature of 4°C seems optimum as it markedly inhibits the growth of mesophilic and psychrotrophic bacteria and at the same time the increase in the values of free fatty acids is slower at this temperature compared to the temperatures of 6,5 and 10°C.
