Technical aspects of robotic milking
 HANKOVEC, Tomáš
The theme of this diploma paper is The technical aspects of robotic milking. This work has been written to provide an overview of the technologies used in robotic milking. In the first part there is a description of the general problems of cattle raising. In subsequent chapters of the work there is a technical description of the selected machine parts used during milking. The next part of this work is made of chapters which deal with the history of robotic milking, introduction of individual manufacturers and technologies used by these producers. Then, these technologies are evaluated in terms of the economic costs of their usage and their technical differences. In the conclusion, there are presented some novelties in the field of robotic milking , coming on the market in the next few years.

FERTILITY OF COWS KEPT IN MODERN TECHNOLOGY
 VRBOVÁ, Aneta
level of cattle breeding is putting growing demands on milk production and it is closely related with fertility. The aim of this work was based on data analysis to determine fertility of dairy cows bred in modern technology in the context of the quality of nutrition, stabling and milk production and determine the level of the relationship between fertility and milk production. Monitoring herds proceeded in two breeds from May 2010 to December 2011. The data was obtained from the reports for monitoring performance, and the accompanying sheets cattle and T4C program (Time for Cows), which records detailed data on milking cows. Overall, more than 19,000 data entries on fertility and yield of cows were statistically evaluated. It was found that dairy cows kept in modern technology, which uses AMS (Automatic Milking Systems) the interval 368.97 days and 406.27 days, which is about 30 or 15.72 less compared with the average of Czech Republic. The value of service period in selected farms was 109.19 and 119.58 days. Compared to the national average is about 12.80 and 3.31 on shorter SP. Insemination interval of 62.63 and 81.06 days was again a 20.36 and 1.93 days shorter than the average insemination interval in Czech Republic in 2010. Correlation relationship between milk production and fertility was found to be statistically significant only for insemination interval rxy = - 0.302+ service period and rxy = 0.402+. The hypothesis, that using AMS does not have a negative effect on fertility was confirmed.
