At the beginning of the work the history of cattle breeding in the Czech Republic is described as well as the process of milking, the issue and the principles of a flow measurement. The second part deals with certification from the association ICAR and with selected flowmeters, too. The main chapter includes the principles of selected flowmeters´ operation. The selected flowmeters of milked milk, which have been certified by ICAR, are described and compared here.
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.
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.
Zhodnocení mléčné užitkovosti dojnic českého strakatého a holštýnského skotu chovaného v totožných podmínkách jedné farmy
Vrba, Jan
The aim of the thesis evaluation of milk production Czech Pied and Holstein cattle reared in identical conditions, a farm was to evaluate milk production Czech Pied and Holstein cattle reared in identical conditions one farm. The literature review has been described primarily cow barn, then we focused on milking his principles and types of milking parlors. The main part of the study was to compare production between Czech Pied and Holstein cattle on farms within TOPAGRI Ltd. based in Topolná, where she had two breeds are identical breeding conditions. The obtained data were statistically analyzed. Results for the period were compared between breeds and monitored with available countrywide data. In this work, we observe that in identical conditions amounted cow Holstein cattle to higher average daily milk production by up to 6.89 kg per cow. Furthermore, we found a comparable fat and protein content, while we have not had the expected significant differences under the two breeds. Regarding the fat content of milk, the best result was recorded in 2013, when the Czech Simmental breed recorded an average fat content of milk at 4.00% and 3.95% of Holstein breed. In 2014, even the Holstein cows showed higher average fat content of milk and 0.05% amounting to 3.83%. For the average protein content was in 2012, the highest distinction in the reference period and 0.33% in favor of Czech Pied breed. In 2014, the average protein content of almost equaled the difference was only 0.03% in favor of Czech Pied breed. Finally, we have seen the development of market prices of milk when the farm gate milk prices tracked farms long staying well below the national average. The highest purchase prices reached tracked farm in 2014, when the average price per kilogram of milk amounted to CZK 9.13. After the abolition of milk quotas in 2015, we have, however, noted a sharp decline in prices, up to CZK 6.75 per 1 kg of milk.
Hygiena získávání mléka a jeho kvalita
Němcová, Michaela
This final work deals with the hygiene of the milk and its quality. These two concepts are closely related, and when we want producing quality milk, it is necessary to examine how the right treatment with milk during and after milking, adequate sanitation and hygiene compliance requirements, as well as right zootechnical principles. The introductory part of my work is focused on dairy farming, ways of their stabling, feeding, and their reproductive cycle. Following the milking process, overview of the types of milking parlors and robotic and multiple milking. This work describes the handling of milk after milking and milk quality and its various parameters. This part deals with mastitis as well as the widely disease of dairy cows. The last big chapter of my thesis deals with hygiene and sanitation basically anything that comes into contact with the cow, the udder or the milk itself, because it is the quality of the resulting milk absolutely crucial.

Vařeka, Jan ; Stádník, Luděk (advisor)
Mastitida je zánět mléčné žlázy způsobený mikroorganismy, které produkují toxiny nebezpečné pro živý organismus. Bakalářská práce pojednává o vzniku, projevech, původcích, diagnostice, léčbě, a prevenci mastitid. Ve druhé části je představena úroveň mastitid na farmě Šedivec. Zdravotní stav mléčné žlázy se především odvíjí od celkové zoohygieny a welfare chovu. S projevením zánětu přichází odpovědnost správné diagnózy a léčby. Mastitidy se řadí mezi nejvýznamnějších onemocnění mléčného skotu. Ekonomické ztráty pro chovatele zahrnují přímé náklady na léčiva a nepřímé způsobené ztrátou mléka poklesem dojivosti či zkrácenou laktací, sníženou reprodukcí, vyšší náchylnosti k další infekci, zvýšenou brakací a pracovní náročností.

Effect of dairy cows housing technology on mastitis occurrence
Brzáková, Lenka ; Stádník, Luděk (advisor) ; Jan, Jan (referee)
The objective of my bachelor thesis was evaluation of quality of housing, milking and making analysis of mastitis on chosen farm. First part of the thesis contains of literature summary about housing technologies, mastitis issues, their detection, originators, therapy and factors affects against their incidence. Thereafter is this part focused on tipes of milking parlours, corect milking procedures and mechanized milking. Materials and methodes of the thesis contains the characteristics of chosen farm where the quality and technology of housing, milking and nutrition of milk cows and other factors affecting presence of mastitis such as taking care of cloven hooves was watched in 2014. The incidence, detection and curation of mastitis was watched afterwards. Montamilk s.r.o. farm cradles 1,200 pieces of cattle and milk cows are about 419 out of it. In the part of thesis named results was watched and evaluated inspection of efficiency in inspecting year 2013 - 2014, which was stated on first lactated cows and on cows which are on second and further lactation. Milk yield was far better with cows on second or futher lactation according to data gathered during the study and expressed by diagram. Diagram of milk components (fat and proteins), which was divided by lactation, was expressed in this part too. Other examinated parameters was occurrence of mastitis - which milk cows, in which season is the occurrence more often, treatment and cost of treatment for one cow. At the end the number of somatic cells for 2014 was represented in diagram for particular lactations. In part of thesis called discusion the comparison was drowed between results from chosen farm and national average of efficiency checks. From results is obvious that milk cow in Mnotamilk has been better in first lactated cows by 427 kg and in second and more lactated cows by 602 kg than is the avarage in Czech republic. Far more the milk components in Montamilk was compared with rest of Czech republic and the results was quite similar. The volume of fat of Montamilk cows was lower in every lactation in comparison with milk cows from Czech. Value of fat in Czech republic avarage first lactated cows is 3,87 % in Montamilk 3,85 % and the value of fat on second and more lactation cows is 3,86 % in Czech average and 3,81 % in Montamilk.
