Faktory ovlivňující počet somatických buněk v kozím mléce
Kocourková, Lenka
The aim of my bachelor thesis is to describe the factors influencing the number of so-matic cells in goat milk. The first part is devoted to the history of goat breeding in the world and the Czech Republic. Some important breeds of dairy goats are described here, including their brief characteristics and also the development of the numbers of the animals kept. The second part describes and evaluates the basic indicators of milk, which are used as indicators used to predict the quality of milk, especially the content of protein, lactose, milk fat, degree of acidity (SH), pH and electrical conduc-tivity of milk. The number of somatic cells in milk is largely influenced by external and internal factors such as breed, nutrition, lactation, health, breeding technology and milking technology and hygiene. This indicator is so significant that it becomes one of the main criteria for assessing the quality of raw milk. Therefore, the last part of the thesis is devoted to the evaluation of the causes of the increase in the number of so-matic cells in milk in relation to external and internal factors and especially in relation to physiology and diseases of the mammary gland.

Optimization design of a mass flow meter for milking
STEHLÍK, Radim
The topic of diploma thesis is the optimization of a mass flow meter for milking. It is a reworking of an already proposed concept that showed major shortcomings in many aspects during the operational testing. The concept for the new proposal was created by using the program SolidWorks. The concept was produced through 3D printer. For the production was due to its properties chosen PET-G copolyester in the form of a printing string. Furthermore, it was proposed to acquire data using a minicomputer Arduino UNO Rev3. The subsequent concept was tested for its functionality. The suggestion of data transmission and its processing using computer technology is also included in this thesis.

Technologické systémy získávání a ošetřování mléka dojnic
BARTŮŠKOVÁ, Markéta
The bachelor thesis used a method of the library research for creating an outline dealing with an issue of milk production and dealing with milk. The attention was focused especially on individual kinds of milking parlours, milking equipment and its sanitation, milking process itself, ways of treating and keeping milk after milking. Different kinds of milking parlours were compared and a summarising evaluation was performed on the basis of this comparison. It was revealed that for the breeders, robotic milking technology is useful because of a limited number of the labour force.

Analysis of dairy milk yields related to changes in livestock breeding environment in ZD Rodvínov
TLACHNOVÁ, Nikola
The aim of this diploma thesis was to analyze milk performance in two centers of Cooperative farm Rodvínov (in Zdešov and in Bednárec) and to find out the level of milk performance in different breeding conditions. The analysis was divided into two parts. Analysis No. 1 was comparing two centers of the farm with different breeding environment in 2012-2015. In Zdešov, the cows were reared in cubicle sheds (capacity 500 cows) and were milked twice a day in 2 x 12 herringbone milking parlor. In Bednárec, dairy cows were reared in an older cubicle shed K96 and K64 (capacity 160 cows), on straw bedding., and grazing during the grazing season and milking twice a day in 2 x 6 tandem parlor. In Bednárec, dairy cows achieved better results in the milk performance, in the fatness of milk, production of fat and protein. A statistically significant difference was confirmed in content ( = 0.001; p 0.001) and fat production ( = 0.05; p < 0.05) in a favor of dairy cows in Bednárec. A statistically significant difference was also confirmed in the milk performance of the same breeding groups reared in the different environment. Analysis No. 2 was monitoring the milk performance of dairy cows in Bednárec between years 2015 to 2018, divided in two periods. Period A - without change of breeding environment and period B - with changes in breeding environment and animal welfare. The first change was the movement of the dairy cows to the year-round pasture run. The second change was the commissioning of the new 2 x 12 side by side milking parlor and final movement to a new modern large-capacity stable (capacity 312 cows). There was no significant difference in the average milk performance of dairy cows depending on the change of breeding environment. During the changes, there was a statistically significant extension of the between calving period and the extension of the 1st calving age. Effect of stress caused by the environment and wellfare changes wasn't statistically significant for the level of milk performance of dairy cows. For the level of milk performance was more important the quality level of breeding management, finding cows in heat and insemination during the period of changes.
