Porovnání získaných informací o množství nadojeného mléka z kontroly užitkovosti a z dojírenských systémů
Žáková, Monika
The aim of this thesis was to compare milking data from farm productivity control and milking systems. Data collection using a PDA was used here as part of a performance check when milk from each dairy cow was recorded manually from a currently calibrated measuring system. The data from the milking system was downloaded from the Farmsoft program, which is used on farms to manage the herd. The comparison took place in 90 dairy cows when 3 lactations were evaluated from each. The difference between the data from the milking parlour system and the KU was confirmed on one of the three farms with more than a 5% probability. The average difference between milk yield was 4.2 kg and the maximum deviation reached 54.1 kg. Several possibilities have been identified as reasons for the difference. The first option is an inappropriate identification device in the form of responders on collars, when there is greater damage and the impossibility of loading dairy cows at the milking parlour. Subsequently, it is possible to point to the different techniques of the milking parlours, where the technology from the BouMatic farm appears to be less reliable. Another possible cause is a misconfiguration of the milking technology with the computer system. Further research into the possible causes of poor identification of dairy cows and the acquisition of innovative technologies for animal identification is recommended.

Hodnocení kvality mleziva dojnic českého strakatého skotu v ekologickém a konvenčním chovu
Buďová, Tereza
The theoretical part aims to provide information about the mammary gland, colostrum, its composition and quality control, types of milk, milking technologies, parlours, and generally about the importance of cattle breading focusing on Czech spotted cattle breed. The main goal of the practical part was to evaluate and compare the quality of colostrum in eco-breeding and conventional breeding. A total of 266 dairy cows of the Czech spotted cattle were included in the evaluation. Dairy cows were divided into individual lactations in order to evaluate the quality of the colostrum in % Brix, the sex of the born calf and amount of milk in liters per first milking. The obtained results were processed and collected into charts. Our results show that the colostrum quality is better in the eco-breeding in Dalečín than in conventional breeding in Věstín. In Dalečín, 114 dairy cows were evaluated. They reached average Brix values of 20.97 % in the first lactation, 20.42 % in the second, 21 % in the third, 25.15 % in the fourth, 23 % in the fifth and 22.17 % Brix in the last lactation. In total, 57 heifers, 53 bulls and 9 stillborn calves were born there. The average milk yield for individual lactation was 2 liters for the first, 4.1 liters for the second, 4 liters for the third, 4.1 liters for the fourth, 6.2 liters for the fifth and 4.9 liters for the mixed lactation. According to these values, we can state that in the eco-breeding in Dalečín the fourth lactation is the best since it reached 25.15 % Brix. In Věstín, 152 dairy cows were evaluated. In total, 79 heifers, 73 bulls and 8 stillborn calves were born. The average milk yield was 20.22 % for the first lactation, 19.95 % for the second, 21.17 % for the third, 20.63% for the fourth, 21.24 % for the fifth and 21.08 % Brix for the mixed lactation. The average milk yield for individual lactation was 2.47 liters for the first, 4.58 liters for the second, 4.17 liters for the third, 6.6 liters for the fourth, 5.38 liters for the fifth and 5.42 for the mixed lactation. We can state the fifth lactation as the best since it reached 21.24 % Brix.

Analýza mléčné užitkovosti u dojnic českého strakatého skotu ve vybraném chovu
Jánišová, Lucie
In this bachelor thesis the analysis of milk yield of Czech fleckvieh cattle in selected breeding was performed, with regard to external and internal influences affecting milk production. The monitoring was carried out for 12 months, in the period from 01/2019 to 12/2019 in the stable Lubník, which belongs to the agriculture company ZOD Žichlínek and result from milk recording scheme. The monitoring was focused on fluctuations in milk production and milk elements, especially fat and protein, depending on individual seasons, the order and phase of lactation. Based on the results, we can conclude that the highest milk yields were achieved by cows at the 4th and higher lactation, dairy cows with a lactation phase of up to 100 days and in the spring period. The highest fat and protein content in milk was found in dairy cows with a lactation phase above 301 days. Dairy cows had the highest fat content in the summer and the highest protein content in the autumn.

Vliv vybraných parametrů chovatelského prostředí na tučnost mléka holštýnských dojnic
Stoklas, Josef
The aim of this thesis was to find out what effect the selected breeding parameters have on the milk fat content of dairy cows. The experiment took place troughout the whole year (from November 2018 to November 2019). Observations were conducted once a month. A total of 160 dairy cows were evaulated and all of them were in the stable with loose litter boxes. Dairy cows were compared at the top and at the end of lactation. The basic life manifestations frequencies of dairy cows were evaluated. These life manifestations did not change during the lactation in the monitored groups. As far as life manifestations are concerned then monitored dairy cows were mostly lying (from 60 %) regardless of the lactation stage. When they were lying down they preferred left side of the body, the difference was 0,5 %. Significant differences were found in milk components of the milk. Significant difference was also in fatness, dairy cows at the top of lactation had 3,86 % of fat and dairy cows at the end of lactation had 4,56 % of fat. The difference was also in the seperated feed. At peak lactation on the upper sieve remained just 4,6 % and at the end remained 18,1 % of feed.

Vliv věku při prvním otelení na mléčnou užitkovost dojnic českého strakatého skotu ve vybraném chovu
Melounová, Andrea
The diploma thesis is focused on the impact of the age of first calving on the milk efficiency of the Czech Fleckvieh - Simmental cattle in a specific agricultural enterprise. The theoretical part describes the characteristics of the Czech cattle, goes deeper into fertility, cows’ reproduction, milk efficiency and its influential effects. In the practical part was depicted a company in Vysočina region where the results of this thesis were evaluated. The data were based on and gathered from the examined enterprise’s January 2017-July 2020 milk recoding. According to the results, it was obvious that the age of first calving does indeed have an statistically significant effect on the dairy cattle’s milk efficiency. It has been concluded that the cows calved in the age of 24 months and younger reached statistically significant (p<0.01) the lowest milk production (7 201 kg). On the other hand, the cows calved in the age of 28 months and older reached statistically significant (p<0.01) the highest milk production (7 859 kg). Also, the dairy cows reached the lowest milk production during their first lactation in all the age groups and the productions kept raising with the number of lactations.

Midwife care for a woman during lactation
KRYGLOVÁ, Aneta
The bachelor thesis deals with the midwife´s care of a woman during Lactation. It is divided into a theoretical part and a practical part. The theoretical part contains information about the anatomy of the breast, lactation, the composition of mother´s milk and its benefits, the principles of proper breastfeeding, difficulties and problems with breastfeeding, breastfeeding support, and finally the cessation of lactation. For the practical part of the bachelor thesis the main aim was to find out what problems women most often face during lactation. Three research questions were set out to detremine this aim. The first research question dealt with where women most often seek help in the event of a breastfeeding problem. The second research question investigates women´s experiences with midwife care in connection with lactation, and the third research question adressed what knowledge and information women lacked. The practical part of the bachelor thesis was done by a qulitative research investigation in the form of individual semi-structured interviews. The research group consisted of ten women who were breastfeeding and had finished their puerperium. All women gave verbal consent to the interview and to its recording on a dictaphone. The women also agreed to the subsequent processing of the information obtained. The research survey took place from February to April 2022. Interviews with women consisted of twenty main questions, which were supplemented by supplementary questions in order to obtain more detailed information. The interviews were subsequently transcribed and analyzed. For data evaluation main categories and subcategories were determined, which are described in the research part of the bachelor thesis. Three categories and fourteen subcategories were created. The results of this bachelor thesis can be used by professional seminars and as informational material for midwifes who, based on our results, can change their attitude towards women and education in the field of lactation.

Vliv vybraných faktorů na dlouhověkost dojnic
ŠLEGLOVÁ, Lucie
This diploma thesis deals with the influence of selected factors on the longevity and milk yield of Holstein cattle in the company ZOD Mrákov. The company provided data on culled dairy cows from the period from 1 January to 31 December 2021, when a total of 316 dairy cows were culled. The causes of culling were found in the-se dairy cows, which were then processed into tables and graphs. In addition, 102 culled dairy cows were randomly selected, which were divided according to breed, age at first calving, lactation order and cause of culling. Of the total number of 102 dairy cows, 60 were red-spotted and 42 were black-spotted dairy cows. In dairy cows, lifetime performance in kg, performance in kg on individual lactations, age at first calving in months, order of lactation and reasons for exclusion were monitored. The data were processed by appropriate statistical methods using MS Excel and Statistica 12. The arithmetic mean and standard deviation (SD) were calculated from the collected data. Baseline characteristics and differences between groups were evaluated using two-way analysis of variance (ANOVA) and t-tests were used to evaluate the level of signifikance. In the statistical survey, only the influence of the breed and the order of lactation on the performance of dairy cows at the level of significance p < 0,01 was found to be conclusive, which is taken as a statistically highly significant difference. Other statistical surveys were statistically insignificant. Nowadays, breeders are more inclined to problem-free, long-lived dairy cows, which have excellent milk production and can withstand more lactations in the herd. Optimally, the dairy cow should conceive regularly, i.e. one calf a year, have good mobility and be durable so as not to require the special care of a caregiver or veterinarian.
