Věková struktura populace plemenných hřebců plemen chovaných v ČR
PÍCHOVÁ, Vladimíra
work deals with the age structure of stallions of selected breeds, which they use for breeding. These are the Czech warmblood, the Old Kladruby horse, the Czech-Komoravian Belgian horse, the Welsh pony and cob breeds, and the Shetland pony. The aim was to explain the concepts associated with horse breeding and breeding activities of stallions. In the work itself, the age structure of stallions of individual breeds was compared, in the categories up to 8 years, 8-15 years, and in the category 16 years and more. The development of these age categories is monitored in 2005, 2010, 2015 and 2020. Furthermore, the mating activity of stallions was monitored according to age, number of matings and births of foals.

Porovnání metabolického profilu u ovcí v závislosti na plemenné příslušnosti a věku
MÍKOVÁ, Eliška
Comparison of blood metabolic profile at sheep was the aim of my Bachelor Work. The breed and age were influenting factors. Hematological, biochemical and mineral parameters were followed. I recieved and evaluated blood samples of 13 females, 1 male and 20 lambs during 2021 - 19th April, 3rd May, 29th June and 22nd October. Getting results were compared with figures from world literature. No significant differences in physiological parameters were found at lambs of Suffolk and Šumavka breed whereas some light differences were found in number of leucocytes, lymphocytes and granulocytes. The changes of metabolic profile depend on the age of animals. Higher values in haemoglobin were measured in the collection on 22 October, leucocytes and urea, and thus seasonal effects were evident.

Vyhodnocení produkčních vlastností ovcí plemene suffolk a charollais v ekologickém chovu
VOSTŘÁKOVÁ, Veronika
The aim of this diploma thesis is to evaluate production characteristics of two breeds of sheep: Suffolk and Charollais. Data for evaluation of characteristics were received from the performance control in years 2016 - 2019. This data were afterwards compared with the nationwide results. This thesis focuses mainly on fertility, fertilization, rearing, number of sheep in reproduction, intensity, evaluation of growth capacity of lambs after birth, death rate of lambs and the difference in number of sheep with single lambs, twins, triplets and quadruplets. In 2016, the average fertilization of the Suffolk breed was 94.1%. In 2016, the percentage of fertilization in the Charollais breed was 97.2%. In comparison with the national results, the average fertilization on the Bočan Farm is higher, in the Suffolk breed by 4.9%. The average fertility per ewed sheep from 2016 - 2019 in the Suffolk breed was 147.4%. The average fertility of the Charollais breed was 159.3% during the observed period. The average intensity in the Suffolk breed was 142.5%. The lowest intensity was in 2016 - 129.4%. The highest intensity of the Charollais breed was reached in 2017 - 164.6%. Another value observed was the weight of lambs after birth and at the 100th day of age. The average weight of Suffolk breed ewes after birth was 2,87 Kg, for rams it was 3,04 Kg. The average weight in the Czech Republic, during the measured period, was 3,1 Kg. The lowest weight of ewes at the 100th day was 28,40 Kg in 2016. The average weight of rams was 30,49 Kg. The lowest weight of Charollais breed ewes after birth was reached in 2019 with value of 2,89 Kg. The highest weight of rams was reached in 2018 with value of 3,27 Kg. The average weight after birth in the Czech Republic is 3,3 Kg. Another parameter monitored was the death of lambs. The most dead lambs in the Suffolk breed were in 2019 - 12 pieces, in the Charollais breed there were the most dead lambs in the year - 2018 - 25 pieces.

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.

Hereditary monogenic health disorders in canine breeds in relation to breeding
ORSÁKOVÁ, Kamila
This thesis deals with problematic of prevalence of single-gene disorders for various dog breeds. The goal was to discover the groups of dog breed with the highest prevalence of single-gene disorders and discover which of these disorders tends to affects most of the dog breeds. We have evaluated 23 closely related groups of dog breeds (Parkerová et al. 2017) with the appearance of some single-gene disorder as we predicted based on our analysis based on OMIA database dated to year 2018-2020. The analysis showed us that the Neuronal Ceroid Lipofuscinosis (NCL) and Progressive Rod-Cone Degeneration (PRCD) affecting most of the dog breeds. We also discovered that the genetically closely related dog breed group 20T, which contains 16 dog breeds, suffers from over 49 types of single-gene disorders. We also discovered that the Border Collie is the dog breed with the highest single-gene disorder prevalence in previously mentioned group 20T. This dog breed is affected by 9 disorders at least. In our analysis the dog breed Labrador Retriever and German Shepherd are suffering from most types of single-gene disorder (more than 15). These dog breeds are one of the most common dog breeds in Czech Republic. This finding supports the hypothesis that the popular dog breeds tends to have better mapped genome and are subjects of testing more often. This thesis provides the characteristic of selected dog breeds. The genetic specifications also contains the recommended breeding method parameters for the minimization of disorders in population.

Prevention of children risk bahaviours in interactions with dogs
NÁHLÍK, Jan
Dog attacks on children are a widespread problem, which can occur when parents fail to realise a potentially dangerous interaction between a dog and a child. The aim of the study was to evaluate dogs attacks to children in Czech households, the ability of parents to identify dangerous situations from several everyday child - dog interactions, determine whether the participants connected these situations to a particular breed of dog and whether participants intend to participate in the dog bite preventing program for them and their children. Data were presented via an online survey to parents of children no more than 6 years old. Data from 208 respondents were analysed using procedure GLIMMIX in SAS program, version 9.3 and Pearson's Chi-squared test in program "R". We recorded 19 dogs attacks on children and children always knew attacking dog. Parents were present and supervised 18 children when attacks happened. Three children had to receive medical help after being attacked by a dog and one developed a post-traumatic stress disorder - a phobia of dogs. Most participants would welcome educating programs about child - dog interactions, more often those who owned a dog (p < 0,05). The probability of risk assessment varied according to dog breed (p < 0.001) as well as to the depicted situation (p < 0,001). Results indicated that Labrador Retriever was considered the least likely of the three dogs to be involved in a dangerous dog - child interaction (with 49 % predicting a dangerous interaction), followed by Parson Russell Terrier (63.2 %) and American Pit Bull Terrier (65 %). Participants considered one particular dog-child interaction named 'touching a bowl' a dangerous interaction at a high rate (77.9 %) when compared with the other presented situations, which were assessed as dangerous at rates of 48.4 % to 56.5 %. The breed of dog seems to be an influential factor when assessing a potentially dangerous outcome from a dog - child interaction. Contrary to our hypothesis, interactions involving the small dog (Parson Russell Terrier) were rated more critically, similarly to those of the American Pit Bull Terrier. These results suggest that even popular family dog breeds, such as Labrador Retrievers, should be treated with more caution.

Breeding and morphological differences of domestic dog
Nový, Jakub ; Figura, Roman (advisor) ; Komárek, Stanislav (referee)
Dog (Canis lupus f. familiaris) is one of the oldest domesticated animals and he has been by our side for several thousand years. Although we know a lot of different domesticated animal breeds but by far it didn't reach such distinction in case of dog. In my work I'll be examinating domestication of this beast and its breeding. Also I'll be dealing with breeds of dogs and especially with morphological differences between them. Key words: Canis lupus familiaris, domestication, breedig, morphology, breed

Šlechtění a návrh standardu zakrslého saténového berana
MRÁZOVÁ, Veronika
The aim of this work was to create a draft for the breed standard of the dwarf satin mini-lop on the basis of information available in literature and from scientific sources. The proposed procedure for breeding a new breed was also executed within the terms of this work. An imaginary breeding pair consisting of representatives of both founding breeds for the new breed was put together. A punnet square was created according to the rules of genetics and Mendel's Laws, which generated a summary of genotypes originating through cross-breeding in the F2 filial generation from both founding breeds. A summary of actually bred individuals was also created from the aspect of exterior traits on the basis of the genotypes and the subsequent procedure for breeding was then proposed in order to achieve the corresponding proposed breed standard in all the bred individuals. According to the draft of the breed standard the dwarf satin mini-lop should have a thickset, short body, without a visible neck. The limbs should be moderately long and very substantial. The forelimbs should be straight. The head has a roman nose and is wide throughout the profile with slightly protruding large eyes. The ears are attached to both sides of the head in a horseshoe shape, with the openings facing the head and a space between the ears of 22 to 28 cm, forming bumps at the root, without any folds, fleshy, with abundant hair and are rounded at the ends. The fur should be dense, elastic, 1.8 to 2 cm long, very soft, with an unusual, very distinctive silky and glittery lustre. All the colours of breeds with normal coats given in the sample book of breeds are permitted without exceptions for spotting or patterns. The ideal weight is 1.20 to 1.40 kg.

Význam rodin v chovu chladnokrevných plemen koní
HOŠKOVÁ, Soňa
The aim of this diploma project is to work out an overviw about temporary cold-blooded horse families bred in Czech republic. Based on breed evidence and information from Approved breed associations the overview is to introduce horse families appearing in cold-blooded breeds (Bohemian-Moravian belgic horse, noric horse and Selezian noric).In individual families all information about their (number of females in the family) are mentioned, according to efficiency tests. Investigation about background of horse breeders helps to gain broader view on cold-blooded horses breeding issue - from the point of viw of motivation, attraction and ambitions of breeders.The source is the serial about breeding codblooded horses written by Jindřiška Svobodová, published in magazine Jezdectví in 2015, entitled: ¨Serial about new generation¨ - which deals with an issue about horses sentenced to scanzens and archives for their redundancy. Results lead to conclusion and recommendation for breed activities of Approved breed association.
