Problematika dojicích robotů DeLaval
ŠVEC, Tomáš
The content of this thesis is focused on the performance evaluation of the DeLaval milking robot in the selected stable. For this work was chosen the family farm stable of Mr. Šítal in the village Mojné. Selected parameters of milking robotic were monitored from 19.9.2018 to 18.3.2019 and on the base of these parameters was evaluated efficiency of the equipment. In this time were followed numbers of milked cows per 24 hours, the average numbers of milking on one cow, the average milking time and daily milk utility. In the selected stable were in a half-year time milked averagely 44 cows with frequency 2,62 utilizations the milking robot per day. The milking took averagely 7 minutes and 40 seconds. Milking utilization was 30,70 liters on one cow per day and total milk herd was 1353,01 liters of milk per day.

Porovnání vybraných ukazatelů welfare dojnic dojených v dojicím automatu a na rybinové dojírně
KOUTEK, Martin
The aim of this diploma thesis was to obtain and formulate the knowledge about the process of milking and the activity of dairy cows 30 minutes after milking in the milking parlour with a robot and in the herringbone milking parlour. Three ethological observations took place in three seasons. The observation on the farm with a milking robot took 24 hours continuously. The observation on the farm with a milking parlour lasted for the duration of milking and subsequent observation of the last group of dairy cows. In total, there were evaluated 452 successful milkings on the farm with the robot and 112 successful milkings on the farm with the milking parlour. Crosses of Czech Fleckvieh Breed and red Holstein Breed in the same ratio were observed during the monitoring. Parameters during milking and ethological performance, such as drinking, feed intake and lying down, in the duration of 30 minutes after milking were monitored. The instructions of the thesis are based on the project NAZV - QJ1210144 and NAZV QJ1530058.

Comparing milking equipment in parlor and in operation with milking robot
MONDEK, Jan
This bachelor thesis deals with the technice and technology used for obtaining of milk. The first theoretical part describes basic important operations during milking and summary of the techniques and technologies. The sekond part of the thesis contains comparing of electrical consumption in parlor and electrical consumption in milking robot.

Selected welfare parameters of milk cows in relation to milking by a robot.
PRŮŠA, Jan
The aim of this work was to gather and evaluate the evidence about the behaviour of dairy cows during the milking by a robot (including physiological reactions running after the milking). The following parameters were observed: number of milking per 24 hours, the time from onset to the robot and the teat cup deployment, the time between milking, the total time of milking, milk yield with each milking, average and total milk yield per day. The results were measured separately in heifers and in cows on the second and subsequent lactations. In the same time, there was also observed the behaviour of cows after leaving the milking robot - feed and water intake, physical activity and the rest for the time of 30 minutes after the milking. Simultaneously, there was also observed the effect of milking technology for the health of the cows, focused on diseases of the mammary gland. There were three ethologic observations which always lasted 24 hours. In addition to the observed data, there were evaluated the data records obtained from the milking machine (e. g. milk yield per one milking, the interval between single milkings, etc.). There were observed an average of 60 pieces of cows. Throughout the watching the cows in the barn behaved calmly and contentedly. They came to the milking machine spontaneously, only a few cases had to be herded for milking by the caregiver. However, they were all the heifers which did not have the sufficient experience with the milking. The counting of teat cup deployment attempts had to be abandoned because of the close proximity of the observer at the milking robot. In this case, the cows were not quiet and did not want to go in the robot spontaneously. The mammary gland disease was diagnosed at an average of 6.9 pieces of milked cows per one month. This high number of cases is ascribed to a poor hygiene of the stables and a poorer quality of feeding. This work was created in cooperation with the grants NAZV QJ1210144 and NAZV QJ1530058.

Evaluation of proposed investment feasibility in animal production.
JENŠÍ, Lukáš
The thesis is focused on the design of the milking robot in a company with herringbone milking parlors and a 220ks cows. The theoretical part describes the milking robots and selecting the most suitable. Custom work includes comparing herringbone milking parlors and milking robot and further economic evaluation and investment evaluation. The essay is based on data from the farm and the data sent from the producers milking robots.

The conceptual design milking parlor using nanotechnology.
KLÍMA, Josef
This thesis follow up research and camparison of commonly used chemicals for disinfection of milking device and alectrochemically adapted water. Research was conducted on two same milking parlor, where one was used chemicals and in the second abeyance periodically reducting the amount of chemicals and electrochemically treated water. The results were compared from patterns of milk. The quantities of chemical subserviences been reduced to 250 grams (41,6%) of the original 600 grams recommended by the manufacturer. This reduction in cost reductions brought to one liter of milk by 0,71 CZK.

Detectionand assessment of noise loading during milking at milking shed.
KŮRKA, Jan
The work deals with the measurement of noise exposure on milking Alfa Laval revoling HBR, Agromilk Pelhřimov dovetail - trigon and milking robot Lely Astronaut A3. When measuring , it was found that the best in terms of noise level measurements published in milking robots with the runing of the feed wagon and measuring worst inside the cell with the milking robots.

Comparison of different ways of cattle lacteal gland preparation before milking
HAJNÁ, Lenka
The objective of diploma work was comparing of different ways of cattle lacteal gland preparation before milking with reference to a milk quality, duration of selected ways of gland preparation and economic costs. There were gradually alleged various ways of gland preparations in parlour of selected agriculture company with breeding of Czech spotted dairy cows breeds {--} the wet, foam and dry way of cleanup. Selected ways of cleanup were applied for a period of three months. The monitoring proceeded in period since April till December 2007.
