Vliv teploty ve stáji na mléčnou užitkovost a pohybovou aktivitu holštýnských dojnic ve vybraném chovu
Vaňkátová, Eliška
The thesis deals with the effect of temperature in the barn on milk yield and locomotor activity of Holstein dairy cattle in a selected breeding system. The evaluation of milk performance was represented by the average daily milk yield, milk components content, namely fat, protein, lactose, somatic cell count and urea content. The literature review discusses the history, characteristics and breeding objective of the breed under study. It also describes the stall environment, heat stress and ways of eliminating it. Dairy performance, locomotor activity and the factors influencing them are also described. Data collection was carried out on the Vadín dairy farm in the Vysočina region. Thirty Holstein, calved within 4 weeks during the January and February. Cows were monitored for one year. The results do not show that the average daily temperature had a negative effect on the average daily milk yield. On the other hand, the effect of average daily temperature on the individual milk components was confirmed. As the average daily temperature increased, the fat, protein and urea content of the milk decreased, while the lactose content increased. The dependence of the number of somatic cells in milk on the average daily temperature was not confirmed. Also, the dependence of physical activity on average daily temperature was very weak.

Janečková, Kateřina
This bachelor thesis is focused on reproduction in cattle, specifically detection of estrus using various methods which aim is to detect estrus in time. In the introduction of a literary section, there are information about fertility, influences that affect fertility and sexual maturity. The summary chapter about physiology of reproduction includes a set of information about genitals, corpus luteum and reproduction cycle, including its hormonal control. Subsequently, attention is focussed on estrus, detection of estrus and methods of detection. Synchronization of estrus, insemination, reinsemination and reproductive indicators are mentioned at the end of the literature review. Practical part is devoted to evaluation of results of the reproduction of a specific company. Two periods are monitored, namely before and after introduction of system Ovalert. Finally, costs of the reproduction are evaluated. The conclusion of the thesis summarizes the methods of estrus detection and evaluates the system Ovalert.

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.

Stav vybraných krevních ukazatelů u dojnic s užitkovostí 11000 kg mléka za laktaci v období puerperia
BASTLOVÁ, Markéta
The bachelor thesis on the topic "Status of selected blood parameters in dairy cows with milk yield of 11000 kg of milk per lactation in the puerperium period" deals with the postpartum period and blood parameters that can be affected in this period. The aim of the study was to evaluate the selected blood parameters in the puerperium periodusing mean, standard deviation, minimum, maximum, coefficient of variation and correlation coefficient. The blood were provided from the breeding of highproducing Holstein dairy cows Chyšná in the enterprise Agropodnik Košetice a.s. with an average milk yield in the observed period of 11553 kg of milk. The most significant changes in all four periods were observed in the lower levels of red blood cell parameters (erythrocyte count, haemoglobin content, haematocrit). Leukocyte counts showed high variability from month to month, with the highest recorder in September 2022 and the lowest in August 2022. Another indicator that changed significantly from the physiological range was glucose concentration in October and November. Alkaline phosphatase was only in a few cases above the upper limit of the physiological range. Total protein and red blood cell indices varied based on the lactation order. The higher the lactation, the higher these values were and vice versa.

Vybrané vlivy na reprodukci dojnic u stáda holštýnského skotu
BENEŠOVÁ, Dominika
Even though the Czech Republic average values of fertility indicators have improved in previous years, their maximum values are still exceeded in individual farms. This bachelor's thesis dealt with the evaluation of selected influences on the overall level of reproduction in the Holstein cattle herd. The aim of my work was to develop a literature review on the reproduction of cow reproduce. The literature review concerned their reproductive indicators, repro-ductive management together with methods of controlled reproduction and the main factors that influence the reproduction ability of a given dam. Another stated goal of this work was to evaluate selected factors that influence their reproduction in a se-lected herd of Holstein cattle. The analysis of fertility indicators and selected influ-ences took place on the Hadačka farm, belonging to company Kralovická zeměděská a.s. 242 cows of Holstein cattle or their hybrids were included in the monitored group, these selected dairy cows met the following criteria: they calved for the first time from 2019 to 2022 and at the same time were admitted, pregnant and calved in this defined time. The following fertility indicators were analyzed in chosen breed: length of ser-vice period, length of insemination interval and length between-calving interval. Sub-sequently, these selected indicators were evaluated depending on lactation order, daily and average daily milk yield, age at first calving and breed. As the lactation phase increases, the period of reproductive indicators is short-ened. The shortest period of fertility indicators (service period -68 days, insemination interval -68 days, calving interval -365 days) was showed by dairy cows in the 5th lactation, and the longest service period (107 days) by dairy cows in the 1st lactation, insemination interval (71 days) for the 3rd and 4th lactation and calving interval (390 days) in dairy cows for the 2nd lactation. Regarding the influence of daily milk and average daily milk yield, it was found that the shortest service period and insemination interval were analyzed in dairy cows with the largest daily milk (46-60 l) and average daily milk yield (56-65 l). On the contrary, the shortest calving interval was found for both daily (8-20 l) and average daily milk (11-25 l) in dairy cows with the lowest value of the milk production. In connection with the age at the 1st calving, it was determined that the shortest time of service period (98 days) and calving interval (380 days) are showed by dairy cows that calved for the first time at an earlier age (636 to 710 days, respectively at 21 to 23 months). On the contrary, the shortest time of insemination interval showed by heifers that calved for the first time at a later age (787 to 950 days, 25 to 31 months). The longest time of service period and calving interval are achieved by heif-ers that calved at the latest age (787-950 days). Comparing fertility indicators between purebred animals and their hybrids, pure-bred animals showed a longer service period (by 2 days) and insemination interval (by 0.5 days). On the contrary, the longest calving interval is shown by hybrids (387 days), which is 9 days longer than that of purebred animals (378 days).

Vliv technologie ustájení dojnic holštýnského skotu na parametry mléčné užitkovosti ve vybraném chovu
Zapletalová, Lenka
The topic of the diploma thesis focuses on the effect of housing technology of Holstein dairy cows on the parameters of milk yield in selected breeding. The aim of the work was to analyze the effect of two different housing technologies in one company, on the parameters of milk yield during one calendar year. The analysis took place from January 2020 to December 2020 in the Dubicka agricultural joint-stock company. For technology A, it was a binding housing with the medium stand. For technology B, it was a free box housing. Data on the number of animals, milk yield, fat content, protein content, order of lactation, lactation phase, and somatic cell number were all obtained and subsequently evaluated. When comparing housing technology A and B, in terms of amount of milk produced, it was found that the housing technology did not have a large effect of milk yield, protein content, and fat. However, it had a major effect on the number of somatic cells in the milk. Compared to Technology B, Technology A showed lower milk yield, higher fat and protein content, lower average lactation order, and higher somatic cell counts for the average annual performance control values. The values from the pool milk samples differed only in the number of somatic cells when technology A showed a higher number. Overall, technology B seems to be promising as it provides animals with better living conditions as well as production conditions, and is more advantageous in terms of labor intensity.

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.
