Vliv změny techniky krmení jadrné krmné směsi ve stáji s robotickým dojením na užitkovost a BCS dojnic
Konupková, Zora
The thesis focuses on the comparison and evaluation of the effect of changing the feeding technique of the concentrate mixture in a barn with robotic milking on the production and metabolic parameters of dairy cows. The parameters studied included milk yield, BCS and rumen fluid parameters. The change in feeding technique consisted of changing the percentage of concentrate presented in the milking robot and as part of the mixed ration. The BCS was evaluated using a five-point scale with a precision of 0,25 points and included 50 dairy cows. Data on milk performance parameters were obtained from Milk Performance Recording and were evaluated in 49 dairy cows. Collection and laboratory examination of rumen fluids was carried out from six animals before the change in feeding technique and subsequently from six animals after the change in feeding technique. For the parameters studied, two groups of statistical sets were created - before the change in feeding technique and after the change in feeding technique, which were subsequently subjected to statistical analyses. After changing the feeding technique, there was a statistically significant increase (p ≤ 0,05) in the production of total volatile fatty acids in the rumen fluid (from 88,33 mmol/l to 107,53 mmol/l). This increase was mainly due to a statistically significant increase (p < 0,05) in propionic acid production (from 15,40 % to 20,65 %) and a statistically significant decrease (p ≤ 0,05) in acetic acid production (from 68,43 % to 63,97 %). When evaluating the effect of the change in feeding technique on milk yield parameters, there was a significant increase (p < 0,05) in fat content (from 3,96 % to 4,18 %) and a significant decrease (p < 0,05) in protein content (from 3,56 % to 3,50 %) in milk in the first month after the change in feeding technique. There was also a statistically significant (p < 0,05) increase (from 24,98 mg/100 ml to 38,24 mg/100 ml) in urea content in milk after the change in feeding technique. There was also a significant increase (p < 0,05) in the mean fat/protein ratio of milk (from 1,12 to 1,20). When BCS of dairy cows was monitored, there was a statistically significant increase (p < 0,05) in the average BCS of the herd (from 3,39 to 3,67) after changing the feeding technique. When the amount of concentrate allocated in the milking robot was reduced, there was a highly statistically significant (p < 0,001) reduction in the amount of residue (from 0,883 kg to 0,203 kg). The results obtained prove that the change in feeding technique had a positive effect on rumen fermentation processes and on the balancing of the nutritional status of the herd.

The problematics of installation of automatic milking systems in cattle breeding
KAMÍROVÁ, Anna
This thesis focuses on the construction of the first automatic robotic milking parlor GEA DairyProQ in the Czech Republic: in the Agrodružstvo Blížkovice. The new milking parlor is then compared to their previous milking parlor DeLaval. The comparison is very difficult because it is the old technology compared to the latest robots on the market, but nonetheless, the results speak for themselves. The milking speed increased by 32 % (40 pcs/hour), the number of people working as operators decreased by 67 % (-4 individuals/shift). The parameters of milk were almost unchanged, except for the number of somatic cells, which decreased by 50,000 in 1 ml of milk and for the value of the total number of microorganisms, which fell slightly under 20,000 in 1 ml of milk. Consumption requirements increased significantly, namely by 40% of energy consumption and by 64% of water consumption. Overall, unattractive, and physically demanding work has become work requiring higher qualification of employees in IT area and in the area of handling new technology. With a few exceptions (20 cows/shift), the worker does not manipulate with the milking arm at all and only looks after the smoothness of running of the milking parlor. This technology has proven to be an independently operating device that greatly simplifies previously demanding work in milking parlors, assuming that you are willing to invest properly in modern technology.

Analýza vlivů působících na produkci mléka a chování dojnic v automatických dojících systémech
Langer, Richard
In this bachelor thesis, the influence of the external environment on the milk performance and behavior of Holstein cattle in a particular company was used, using the technology of robotized milking from Lely. The subject of observation was mainly the average daily milk yield, the order of lactation, the time and frequency of milking depending on climatic conditions. The data were continuously collected during 2018. It has been found that the external environment significantly contributes to the milk performance of cattle. Among the proven influences was the order of lactation, which mainly contributes to the daily production and milking speed. In addition, the season of the day, when daily production, milking rate and milking frequency varied depending on temperature, was followed. The research revealed that dairy cows reach the highest production in the second and third lactation. Furthermore, the influence of the external environment significantly affects the daily production of dairy cows and the speed of milking.

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.
