Changes of the meat quality meat characteristics during storage
ZIEGLBAUEROVÁ, Karolína
The bachelor thesis is focused on the evaluation of quality characteristics of beef during its storage. The literature review defines the term beef, the consumption of beef in the Czech Republic, describes its chemical composition and properties. In this work The paper evaluates the factors that affect the quality of beef and their distribution. It is further characterized by the maturation of meat, then its storage. The practical part is focused on the measurement of basic analytical components in the muscle of cattle, originating from their own breeding and from a farm with comparable breeding conditions. The aim of this bachelor thesis was to compare the properties of meat of three breeds of cattle, especially to determine the changes in the basic analytical values of meat during its long-term storage. The amount of water, protein, fat and collagen was monitored using a NIRMaster instrument and the results were then compared.

Vliv věku při prvním otelení na užitkovost a dlouhověkost dojnic
DRÁB, Zdeněk
The main significance of the diploma thesis was to evaluate in a clear form the influence of the level of heifer rearing and age at the first calving on the performance and longevity of dairy cows of Czech spotted cattle in the herd of Agro Kunčina a.s. Data of 390 dairy cows for the last five years were used. The data obtained were sorted according to key indicators, namely age at first calving, age at weaning, performance at first lactation, lifetime performance, milk content, order of lactation and causes of weaning. The available statistical methods were used to evaluate the effect of age at first calving on performance, longevity, causes of exclusion and content of milk components..

Analýza vybraných vlivů na mléčnou užitkovost a plodnost u stáda českého strakatého skotu
KROPÁČEK, Roman
The analysis of selected effects on milk yield and fertility in a herd of Czech spotted cattle deals with some effects observed on the basis of milk yield control data. The observed values are performance for standardized lactation, fat and protein content in milk, length of interval, service period and insemination interval. The age at first calving and its effect on milk yield as last factor. In period 2016 - 2018 are compared diary cows in their first three lactations. In the first part of the Bachelor thesis the history is processed and brief description of Czech spotted cattle. The following chapters deal with milk yield and fertility and selected factors mentioned above. The experimental part of the work presents the company where the observation was performed. The results are evaluated and presented into tables and graphs and then compared with the national results and according to the available literature.

Zhodnocení reprodukčních ukazatelů ve vybraném stádě skotu
KUBECOVÁ, Monika
Prosperous reproduction is the basis for every successful breedinf, i tis the most important factor, which testifiest the overall quality of breeding. In the Czech Republic. reproductive indicators are currently deteriorating. The aim of the work was to prepare a literature review of cattle reproduction, influences on eproduction and to characterize the breed Czech spotted cattle,. The aim of the monitored set of dairy cows of Czech spotted cattle was to evaluate tho effects on selected fertility indicators and evaluate them. In the selected breeding of Czech spotted cattle were evaluated selcted indicators of reproduction (interval, service period, insemination interval) of selected dairy cows (120 pieces) were evaluated for the monitored period of 2 years, from 1 January 2017 to 31 December 2018. These indicators werw further evaluated according to individual factors (influence of lactation order, influence of milk yield and influence of age at 1st calving)

Analýza vybraných vlivů na reprodukci dojnic ve vybraném stádě českého strakatého skotu
CIMBŮRKOVÁ, Pavla
The bachelor's thesis on the topic "analysis of selected effects on the reproduction of dairy cows in a selected herd of Czech spotted cattle" was prepared in the company JASANKA, s.r.o. In the literature review, the author first describes the importance of cattle in general, then focuses on Czech spotted cattle. In the next part, which focuses on the reproduction of cattle, the author describes the female reproductive system, the reproductive period from fertilization to childbirth, selected fertility indicators and also the effects that affect the indicators. In the chapters of own work, she analyzes the monitored data, which she collected for a period of two years. She focuses on the effect of performance on reproductive indicators from data from ninety randomly selected dairy cows. Furthermore, she focuses on the influence of the father on fertility indicators. Here she selected three proven bulls used by the company and evaluated data from another ninety dairy cows. As the monitored dairy cows migrated during the analysis, it also included the effect of housing on fertility.

Analýza užitkovosti u masného skotu plemene Hereford
MAZALOVSKÁ, Lucie
Theme of this work is breeding of cattle meat breed Hereford breed and their crossbreds with Charolais and Czech spotted cattle. We monitored the influence of sex, breed of father and mother, parity and month of calving on the average weight of calves at 120, 210 and 365 days of animal age. Growth of calves in individual cross combinations were evaluated too. The study was performed on the selected herd of 215 pieces of cattle: 85 of Hereford breed, 68 of Charolais breed and 62 of Czech spotted cattle breed. The herd is bred on the private farm with a total area 90ha of pastures located in the South Bohemian village Lhota near Mladosovice. We used information and performance of the herd of cattle between the years: 2017 and 2018. This diploma thesis confirms that higher average weights can be attain as crossbreeding of meat breeds and also by crossbreeds with dual purpose cattle breeds. Calves born in the late months of the year come up to higher average weights too. From the statistical analysis it is possible to prove the influence of the parent combination on the average weights of calves and their weight gains. The lowest weight gains were observed in calves of crossbred combination of Charolais vs. Czech spotted cattle (0.83 kg per day) and the highest values were detected in calves of Charolais vs. Hereford breeds (1 kg per day).

Performance and reproduction of Holstein cattle
KAMENÍKOVÁ, Jana
The aim of thesis was to analyze the milk efficiency and fertility of dairy cows of Holstein cattle breeding under intensive conditions. The examinations were made in the agricultural company ZDV Krchleby, a.s. during the year of 2007 to 2009. In total, 147 dairy cows were used for observation including 35 Holstein dairy cows (100% H, R 100%), in a group called - H1, 70 Holstein cows crossed with Czech spotted cattle (H 75 - 87%, R 75 - 87%) in group - H3 and 42 Holstein cows crossed with Czech spotted cattle (H 50 - 74%, R 50 - 74%), in group - H4. Furthermore, the basic data set was divided according to lactation into four groups: 1st lactation, 2nd lactations, 3rd lactations, 4th and more lactations. The main indicators for evaluation of the milk efficiency were the: milk quantity (kg), amount of fat in the milk (%), production of the fat in the milk (kg), amount of protein in the milk (%), production of protein in the milk (kg), content of lactose in the milk (%), persistency of lactation and lactation duration (in days). In terms of fertility, the following factors were evaluated: the cow?s age at first birth (in days), insemination interval (in days), service period (in days) and the periods between births (in days). The cows in the first group milked on average of 8945.03 kg of milk, the amount of fat was 3.66%, the content of protein was 3.32%. Cows in the second group milked an average amount of 8186.55 kg of milk, the content of fat was 3.77%, the amount of protein was 3.33%. The third group milked an average amount of the milk 8649.05 kg, the content of fat was 3.58% and the amount of protein was 3.26%. Differences between these groups were not statistically significant. From the reproductive indicators, statistically, the only most significant difference was the time in between births. The longest period in between births was measured in the first group - 576.22 days, in the second group - 487.38 days and in the third group - 480.95 days.
