Zhodnocení zařazených plemenných hřebců v chovu českého teplokrevníka po roce 2000
Kotková, Simona
The aim of the thesis was to create a literature search of the Czech warmblood bred, important breeds involved in its breeding and subsequent analysis of breeding stallion approved for Czech warmblood breeding in individual years from 2000 to the present. The basic database consisted of 530 stallions belonging to 14 different breeds. Out of the total number of sires, the Czech warmblood horse was the most represented during the entire period of 22 years, at 31,13 %. Of the foreign sport breeds, the Holstein horse breed was the most represented at 15,28 %. The average sire was included in breeding for 11 years, while during his breeding period he produced an average od 26,08 offspring. Of the total number of 530 horses, 26,23 % were stallions from local stud farms (ZH) and 73,77 % were private stallions (S). Of the total number of offspring (13,825) of all sires, ZH offspring accounted for 38,68 % and S offspring for 51,32 %. The largest representation of own jumping and dressage performance was in jumping performance S-ST** 26,98 % and in dressage L 4,72 %.

Parental Care in Insects and its Didactic Use in Teaching
Mázdrová, Vendula ; Říhová, Dagmar (advisor) ; Šípek, Petr (referee)
In my bachelor thesis, I focus on parental care in insects, its types and forms. At the same time, I present in more detail a parental care of offspring in individual representatives of insect orders. I also explain the concept of eusocial insect. In this part of my thesis I also focus on the research of literature, which in closer look describes orders of insects and parental care of their offspring. In the second, practical part, I first analyse primary school nature science textbooks to determine the extent to which parental care is taught in primary schools. I further analyse the school curriculum (SCP) and the thematic plan at a particular elementary school in Davle. I also develop didactic tools suitable for teaching - a worksheet and three didactic games that can be used in teaching nature science in the sixth grade at the primary school. Two of the created didactic tools were used in an implemented lesson at the elementary school in Davle. Finally, I write about the course of the lesson, its objectives, and I clearly describe its different parts chronologically. Finally, I summarize the lesson and compare it with similar didactic methods used by other authors in their works. Key words: social insect, offspring, parental care, lesson, game, worksheet

Zhodnocení významu plemeníka Scyris v chovu českého teplokrevníka
Kubíková, Zuzana
The aim of this diploma thesis was to evaluate the significance of the stud horse Scyris in the breeding of the Czech Warmblood. To evaluate the stud horse we used his offspring born in the years 2011 to 2016. Two underlying databases were then created in the programme Microsoft Office Excel 2007. The first was used to assess linear regression and the second to assess correlation using the Pearson correlation coefficient. Escalation of the linear regression and the Pearson correlation coefficient was carried out using the statistics software UNISTAT 6.5. All of the data entered in the underlying database were acquired from the website of the Association of Czech Warmblood Breeders. From the total information obtained about stallion 6062 Scyris (POL) it is evident that he was most favoured by Czech Warmblood breeders in the year 2013. Furthermore, it was determined that there is a higher percentage of colts than fillies among his offspring. When monitoring exterior variability in 14 daughters that have been assigned a class and their dams, we recorded the minimum, maximum and mean values of the basic body measurements both numerically and graphically. On the basis of aggregate statistics from these measurements, it can be stated that the dams are unbalanced in exterior terms, and stallion 606 Scyris (POL) did not succeed in balancing out this variability in his daughters. In the next step, the correlation dependence of individual body measurements was assessed in daughters and dams. It was determined that there is medium correlation dependence between the attributes KVP (tape withers height), KVH (stick withers height) and Ohol (cannon bone circumference), so it can be said that the influence of dams on the bone mass and withers height of daughters is probable but is not conclusive. With the attribute OH (chest circumference) low correlation dependence between dams and daughters was recorded. This suggests that the dams have a lesser influence on the bulkiness of daughters, and that stallion 6062 Scyris (POL) has a refining effect on the build of his offspring. When assessing the linear regression, we recorded a decreasing tendency of the regression coefficient with regard to offspring class which exhibits 16% reliability and according to our test emerges as statistically conclusive. So the assessed class of daughters of the sire 6062 Scyris (POL) does not improve but on the contrary, it decreases slightly. A high value for the downward trend was recorded with the jump index of the dams and is documented by 21,66 % reliability. Our test emerged as highly statistically conclusive and we can conclude that the mares mated with stallion 6062 Scyris (POL) are of relatively low quality in performance terms. Our final step was to analyse the colouring of offspring, where it was determined that grey colouring was present in 58 % of the offspring. On the basis of an evaluation of the dams and offspring, it was concluded that stallion 6062 Scyris (POL) carries a heterozygous set of alleles in the G gene, which influences the grey colouring of horses.

"To your descendants I will give this land" (Gen 12:7): Topical study on the gift of the land in the Hebrew Bible
Michnová, Jaroslava ; Sláma, Petr (advisor) ; Čapek, Filip (referee)
The theme of the essay is the mapping of the country/land theme in the Hebrew canon from the basic division of the individual word meanings along with brief characteristics and statistics of occurrences of each of these meanings in the canon, through a detailed focus on specific one - the Promised Land. The meaning is monitored in terms of content and theological significance with regard to the storyline of the text. Attention is focused on individual occurrences of words in the Hebrew text and on their specifics, but also on combining elements from the perspective of the entire canon of the Hebrew Bible.

Performance recording in Charolais beef herd
Jelínek, Petr ; Toušová, Renata (advisor) ; Petr, Petr (referee)
Summary
In this thesis I dealt with verification of performance of beef cattle Charolais Breed on farm: Chov Charolais spol. s r. o. Slabce. The main objective of my diploma work was to assess the growth abilities of calves Charolais breed from birth till weaning in relation to various factors, for instance: gender, order of calving, number of born calves during one calving, month and year of the birth on the respective farm. The relevant data was assessed for the period of years 2012 - 2015. In this period there was born 324 calves of which 162 bulls, 153 heifers and 9 still born calves. The assessment of calf's growth characteristics was related to the average birthweight, average gain from birth to 120 days, and average weight at the age of 120 and 210 days. For the evaluation of calf's growth characteristics was used data gained from the database of performance testing of beef cattle (KUMP) for the given period. Growth parameters related to selected factors were processed with the use of statistical software SAS 9.3 (SAS 9.3, 2011).
The average weight of young bulls at birth was 33,58 kg and average weight of heifers was 32,99 kg. The average weight of bulls at the age of 120 days was 183,66 kg and the average weight of heifers was 175,58 kg which was demonstrated to be statistically significant (P < 0,01). The average weight of bulls at the age of 210 days was 288,28 kg which is again higher than heifers with average weight of 264,21 kg (P < 0,05). To summarize, there was identified statistically significant difference of the gender influence in behalf of bulls.
After comparison of average weight at birth, at the age of 120 and 210 days separately for twins and an only child, there is obvious and also statistically significant finding (P < 0,01) that the observed twins are usually smaller at birth and their growth abilities are worse than that of only child. The average weight at birth for an only child is about 4,48 kg higher compared to twins. Then the average weight at the age of 120 days for an only child is about 38,68 kg higher than average weight of twings. Finally the average weight at the age of 210 days is about 58,26 kg higher for an only child.
Regarding to the influence of order of calving there was identified no significant effect to both average birth weight and weight at the age of 210 days. The only statistical significance was identified between order of calving and the average weight at the age of 120 days in 1st, 2nd, 5th, 7th, 10th order of calving (P < 0,05). Further I found out that calves in the 1st order of calving have significantly lower average weight from the 1st calving mothers at the age of 120 days than the calves in the 2nd, 5th, 7th, 10th order of calving. The average weight of calves at the age of 120 days is about 9,29 kg lower than weight of calves in the 2nd order of calving. On the other hand the average weight of calves at the age of 120 days in the 5th order of calving is about 18,37 kg higher than weight of calves in the 1st order of calving. Similarly, calves in the 7th order of calving have about 13,63 kg higher weight than calves from the 1st calving mothers. And also calves at the age of 120 days in the 10th order of calving have about 15,78 kg higher weight than calves from the 1st calving mothers.
In respect of influence of year of birth was identified statistically significant different level (P < 0,01) of the average birthweight in year 2013 compared to other years. Similarly there was demonstrated the statistically significant difference (P < 0,01) regarding to the average gain from birth in year 2013 compared to other years. The average birthweight in 2013 was 34,91 kg. The lowest average birthweight of 31,65 kg was observed in 2015. And for instance in 2012 the average birthweight was 32,48 kg which is still about 2,43 kg lower than in 2013. Regarding the evaluation of the average gain from birth till the age of 120 days there was only reported value of 1046,78 g in 2013. The best year regarding the average gain from birth till the age of 120 days was year 2014 which represented value of 1214,37 g.
In the observed breed there took place births predominantly from January till June. Regarding the month of birth there was demonstrated statistically significant difference (P < 0,05) in respect of average birthweight of calves born in May 31,98 kg compared calves born in February 32,55 kg and in March 33,07 kg. Further was identified statistically significant difference regarding the average gain from birth for calves born in June 995,28 g compared to calves born in February 1197,87 g (P < 0,01). Similarly in March was reported value of 1181,18 g (P < 0,05). The last statistically significant difference (P < 0,01) was identified in respect of average weight at the age of 210 days of calves born in May 199,55 kg and in June 201 kg in comparison to calves born in January 282,05 kg, in February 284,65 kg, in March 277,21 kg and in April 277,76 kg. To conclude, based on the statistical analysis, conclusive results and literary sources there had been confirmed hypothesis that internal factors positively affect the growth abilities of calves.

Importance of the presence of parents for the eggs development and fry mortality in fish of the genus \kur{Hemichromis}
MICHALIČKA, Petr
Through this experiment there was examined the effect of the presence of the parents in the development and mortality of fish spawn of the genus Hemichromis. Hemichromis guttatus was selected for this experiment as a model species. It was found that the parental care in the fish genus Hemichromis is most needed during the period when the offspring is in the stage of eggs. In this stage, the absence of parents showed higher level of mortality (greater number of attacked by mold eggs left without parental care). In other developmental stages of the offspring the parental care was not a great advantage, on the contrary, in some cases allowing parents to take care of the screed was a disadvantage due to cannibalism.

A PROPOSAL OF THE SYSTEM OF INFORMATION FOR BREEDERS OF WARM-BLOOD HORSES
HAVLOVÁ, Lucie
The aim of this work was to compile a summary of the information provided to the public breeders by the five warm-blood horse breeding organizations in the Czech Republic. Mentioned horses are used for sporting purposes. A similar report was done on the extent and quality of information provided to the public breeders in neighboring European countries. We had prepared a proposal for a system that would provide the necessary information for effective breeding work . In the Czech Republic there is a system for collecting information about the population of horses. However, it is necessary to evaluate and publish information in an understandable form to breeders. As a basis for the preparation of tabular overview of the number of warm-blood horses bred in the Czech Republic, were collected the data from the Central horse register website and data from yearbooks and websites of individual breeders associations. Data were collected for the period of 2006 - 2013. In this thesis the processed data covers these breeds: Czech warmblood, Slovak warmblood, Moravian warmblood , Kinsky horse and Czech Traken. We have suggested the system, configuration and method for disclosure of the breeding information for warm-blood horse breeders and there is also recommended the annual frequency. As a model stallion was chosen Dutch warmblood Great Pleasure and we have created an information portfolio of this stallion. The system of the published information includes identification of the horse, pedigree, exterior evaluation, the results of his performance, comparing features and characteristics of the offspring population and the average breeding value estimation for exterior and performance. An important point is to make the overview of births and evaluated offspring. The proposed system should allow the improvement of the current breeding process and provide objective information to breeders for the right breeding decisions.
