Reprodukce a management chovu vybraných plemen masného skotu
NÁVAROVÁ, Eliška
The literature review presented in the bachelor thesis focuses on the ma-nagement and characterization of cattle breeding, specifically the Aberdeen Angus, Limousin, and Charolais breeds. The following chapter describes ecological ag-riculture, as the thesis includes companies that breed cattle in organic farming. The upcoming chapter of the thesis centers on the reproduction of beef cattle breeds. The aim of this thesis was to conduct a comprehensive and continuous analysis throughout the year by which to evaluate the level of reproduction and ma-nagement. The practical part focuses on evaluation the course of delivery, pregnancy diagnosis results, weight of calves at birth and weaning, and the results from semen examination. The data for this thesis were collected from six companies using ac-companying lists of cattle, animal husbandry records, and bull spermograms. In the conclusion of the thesis, the results are summarized and evaluated. Companies specializing in Limousin and Charolais breeding include their bulls in herd for approximately two months. The company that focuses on breeding Aberdeen Angus has its bulls in herd for most of the year. More frequent occurrence of difficult births was recorded for the Limousin breed at the Rolnická Skalná company, and their number significantly exceeded the average incidence of complicated births for this breed. A higher incidence of di-fficult births was also analyzed for the Charolais breed at the SPO-ZEM Nový Kos-tel company. The number of difficult births recorded at the company specializing in breeding Aberdeen Angus slightly exceeded the breed's average. The highest success rate of pregnancy was found in the companies SPO-ZEM Nový Kostel, Farmy Třebeň, and Anonymu. The Naturland company achieved unsatisfactory levels of pregnancy rates. Companies breeding Limousin achieved lower birth weights, nonetheless the values were satisfactory. Weaning weights of calves in these companies were suita-ble. Companies focused on breeding Charolais achieved unsatisfactory average birth weight values but excellent weaning weight values. For the Aberdeen Angus breed, satisfactory average weaning weight was achieved for heifers, while the weight of bulls was lower than usual for the breed. From the total of 12 monitored bulls, all were fertile at the beginning of the breeding season, infertility was diagnosed in three bulls, and one bull had a high number of immobile spermatozoa. In these bulls, a treatment was applied, which was found to be effective only in two breeding males after the third collection. Bulls for which the treatment was ineffective were removed from the breeding pro-gram.
Základní aspekty výživy nosných plemen slepic
PAPOUŠKOVÁ, Tereza
This bachelor thesis deals with the proper nutrition of hens intended for egg production. These are mainly laying hens kept in large farms. It deals with information about the best purebred breeds bred in our country in small farms and laying type hybrids used in large farms. Furthermore, the anatomy and physiology of the digestive tract of the hens, a general treatise on nutrients, minerals and vitamins. This information is then closly describe in more detail with regard to specific categories of animals and their needs.
Variability of the domestic chicken breeds in selected immunological traits of hen and egg
Bílková, Barbora ; Vinkler, Michal (advisor) ; Plachý, Jiří (referee) ; Trefil, Pavel (referee)
The avian immune system is a complex system of defence mechanisms that protect bird hosts against threats from ubiquitous pathogens. According to the co-evolutionary models, variability in immune traits of hosts is the key component providing ability to adapt and enhance their defence mechanisms in presence of constant selective pathogen pressure. Domestic chicken (Gallus gallus f. domestica) is used as a model organism in avian biology and also is one of the most important food-producing animals, not only for their meat but also for the egg production. Unfortunately, in research usually only inbred chicken lines are used and modern poultry husbandry is tight with unilateral breeding towards highly productive breeds. Those approaches decrease intra-population polymorphism in chickens. However, especially in case of farm animals, searching and extending the pool of immune variability and enhancing pathogen resistance is crucial for sustaining healthy and biologically secure populations and their products. Morphologically highly distinct traditional chicken breeds, which have evolved for hundreds years under different selective pressures, may represent this desirable immunological variability. In my thesis I described variability in chosen immunological traits, haematological parameters and proteomic...

Opinions of Primary School Students on the Dangers Posed by Selected Mammal Species
Benešová, Šárka ; Andreska, Jan (advisor) ; Hanel, Lubomír (referee)
This thesis builds on my bachelor thesis "Selected mammals in elementary and secondary education". It deals with the opinions of 8th and 9th grade pupils of elementary schools on the dangers posed by selected mammal species. Among the selected species in this work are brown bear (Ursus arktos), wolf (Canis lupus), lynx (Lynx lynx), fox (Vulpes vulpes), dog (Canis lupus familiaris), and wild boar (Sus strofa). All these animals are found in the territory of the Czech Republic. In addition to the perception of dangers posed by these mammals, the thesis also ascertains knowledge of and attitude towards these selected species. The pupils also expressed their opinions about dog breeds and stated whether they currently had a dog, or had had one in the past, and if so, what kind it was. The study was conducted on the basis of a questionnaire survey. Questionnaires were given out at primary schools in areas, where some of the beasts abide (brown bear, wolf, lynx). The work also contains information about individual mammal species that were studied as well as the introduction of the domestic dog, its domestication and an overview of dog breeds. Key words: bear, wolf, dog, lynx, fox, wild boar, breeds
Proteomic differentiation of hairs of different dog breeds
Humpoláková, Karin ; Kučková, Štěpánka (advisor) ; Kolář, Karel (referee)
The goal of my thesis was to find out whether it is possible to distinguish among individual dog breeds from the protein analysis of their fur. This knowledge could be used, for example, in forensic science. In this work, there was also a comparison of the similarity of dog breeds with a wolf, which was domesticated and is considered as an ancestor of the dog. For this study, the hair of three representatives of sixteen dog breeds was collected. To analyse these samples enzyme cleavage was used a trypsin, and mass spectra were obtained by MALDI- TOF MS (Matrix-Assisted Laser Desorption/Ionization - Time of Flight Mass Spectrometry) and LC/MS-MS (Liquid Chromatography with Tandem Mass Spectrometry) methods. The obtained data were evaluated by the PCA (Principal Component Analysis) and LDA (Linear Discriminant Analysis) method. It was found, that individual dog breeds cannot be distinguished using both methods. KEYWORDS proteomics, coat, dog, breeds, mass spectrometry
