Systémy pro rychlé analýzy mléka v dojírnách
DURČANSKÁ, Michaela
The first part of my bachelor's thesis, consisting of a review of available literature sources, deals with the description of the properties and composition of cow's milk and the use of milk quality indicators in the management of dairy herds. Furthermore, this bachelor's thesis contains a detailed description of various types of milking parlors as well as criteria for their selection. The second part describes in-line milk analyzers that are available on the market and are used in the milking processes. Using various sensors, these analyzers measure milk components (proteins, fats, lactose, somatic cell count, enzymes, blood presence), milk properties (color, temperature, electrical conductivity) and the amount of milk milked in real time during milking from individual cows. In practice, milk analyzers from Afimilk, Lely, DeLaval, LIC Automation, Fullwood Packo, GEA and Boumatic are the most widely used ones. The basic disadvantage of analyzers is the lower accuracy of measurement compared to laboratories. To reach more accurate results of measurement, further research and development of these technologies is important. Potential methods include infrared spectroscopy, biosensors, or the ATP bioluminescence method. However, the inaccuracy of the results does not prevent those from being used in assessing changes in measured values and trends over time. Further development of a device that could directly determine the number of somatic cells in milk would be needed. This would make monitoring the incidence of mastitis more accurate than the previously used but less reliable changes in milk conductivity. The use of such a device would make the prevention and treatment of mastitis more effective, especially in robotic milking.
