History, development, and present breeding trends in aquaristics The presented diploma thesis is based on empirical research, and deals with the history, development, and current trends in aquaristics. The theoretical part is focused on qualitative content analysis of relevant specialized literature. This thesis defines history and development of aquaristics in the world, as well as in our country, and compares current and past aquarium equipment and methods. In this work are presented and described current trends in modern aquaristics. The text is complemented by contemporary drawings and layouts of historical and recent equipment and technology. The research part is focused on data obtained from quantitative content analysis of aquarium publications, where is observed frequency of mentions in the text of particular species of aquarium fish. At the same time the results are compared with the content analysis of statistical data of aquaristics portals aimed at the real preferences of breeders. From the conclusion results that in their articles the authors preferred some of the selected families in each of the examined periods. Most preferred family was Cichlidae, Characidae and Cyprinidae. However, often presented species of aquarium fish do not correlate with the real preferences of modern...

Abstract Agriculture has a significant part in environmental pollution. Gass emissions from breeding livestock have a great impact on the environment as well as exhaust emissions. However, the most negative environmental impact from the emissions of gases is ammonia. For this reason, this diploma thesis focuses on the evaluation of the production specific ammonia emission from the selected breed. Furthermore the diploma thesis focus on the evaluation of carbon dioxide, methane, and nitrous oxide emissions in the selected agricultural operation. The measurements have been done in a state enterprise: International Poultry Testing, located in Ústrašice.

The thesis is focused on the study of the recovery of selected rural farmhouse in the village Kobeřice at Brno in the South Moravian Region. It is suggested that the fundamental design, layout, technological and operational solutions object. In this work, one solution is designed so that the sound use of resources, protection of the environment, waste management, but also respect local rural architecture, reflecting trends in contemporary rural development and agriculture. While processing is based on information collected in the field, tutorials, knowledge processors from literature, the web and other sources. The thesis also includes photographic and graphic documentation including external visualization object.

The aim of this thesis was to obtain and evaluate information from behavioural monitoring of beef cattle herd (cows, bull, calves) reared in the suckler system in the year-round grazing. The beef herd situated in the Pilsen region near Přeštice and is owned by private breeder was chosen for observation. Basic herd consisted of 20 cows with calves and one Charolais sire. There were three ethological observations, two observations in 2014 and one observation in 2015, duration of observations was 24 hours. The course of each category of behaviour was recorded by interval group method with interval length of 5 minutes. Activities as feed intake, rest, standing and movement. It was also reported comfort, sexual and maternal behaviour within the herd. The longest period of cows feed intake was recorded at the end of the grazing season (30.56% of the day, i.e. 7.33 hours). In contrast, feed intake took cattle in the winter months only 28.31% of the day (6.8 hours). Values in the standing category were not substantially different during the year. The longest standing time in the spring and autumn (5.97 hours respectively. 5.95 hours), standing time in the winter was shortened to 5.56 hours. Locomotion activity of animals in the spring reached 7.78%, i.e. 1.87 hour and due to the fact that cattle was still fed hay, but also first low vegetation started to grow in some areas and animals on its wintering actively sought it. In contrast, in the autumn the value was only 2.43%, i.e. 0.58 hours of the day due to sufficient suitable pasture. In the winter due to bad weather conditions, the value also decreased to 7.8%, i.e. 1.88 hours of the day. The longest representation of rest category in form of laying was recorded in the herd in autumn at level of 10.13 hours of the day (i.e. 40.22% of the day). In the spring rest category took 9.00 hours (i.e. 37.48%). The form of animal husbandry at the farm was in correspondence with the natural biorhythms of the animals and allowed them to freely demonstrate natural instincts and behaviour. Based on the findings it is possible to judge that the system of suckler beef herds is useful in terms of ensuring animal welfare and Charolais breed is exercisable under those conditions.

This work evaluates the movement of the Welsh pony breed in the Czech republic.. The aim was to evaluate numbers of population, evaluate the movement in walk and trot and evaluate the linear score trait. Basic parameters were measured (length of stride in walk, length of stride in trot and the frequency). For this evaluation the following effects were chosen: sex, breed section, country of origin and scapula angle. 348 individuals of the Welsh Pony and Cob breeds were entered into the database for linear score and 80 individuals of the Welsh Pony and Cob breeds were entered into database for movement evaluated, of which 20 animals were section A and 20 animals section B, 20 animals section D and 20 animals section D. We measured the data with a laser measure and a special pedometer in the Czech republic, the Netherlands and The Great Britain. The relationship between the length of stride in walk and trot was investigated in comparison to the wither height, the animal's sex, its country of origin, breed section and the angle of the scapula. A conclusive (P less than or equal to 0,05) influence was also observed for the effect of section. By comparing the spaciousness in walk and trot according to the chosen effects of sex, scapula angle, adherence to section and country of origin, we proved a highly conclusive (P less than or equal to 0, 01) influence of the scapula angle and a conclusive (P less than or equal to 0, 05) influence between section A and D, section B and D, section A and B, A and WPBR and B and WPBR. Multiple comparisons showed a conclusive difference in the effect section for sklon a tvar zádě. The length and type of back was conclusive difference for the effect sex, include the traits back, pastern and loins for effect age.

The aim of this thesis was the first part of their work to process data on the number of foals born, import and export, trends in breeds of horses Shagya Arabian (Sh-a) and data horse's active Sh-a in the Czech Republic for the year 2014. The data were processed in Microsoft Office Excel 2007 and have created graphs. However, the number of foals born, it was found that most of them were born in 2009 and 2002. Import greatly outweighed exports, but in recent years also began to flourish and export. States Shagya-Arabians in the Czech Republic since 1994, continues to grow. In 2014, the Czech Republic 283 broodmares, 176 geldings, 142 mares, 133 stallions and 31 sire. In the second part of their work was the aim statistically evaluate data mares entered in the Stud book. This program was used Unistat 5.5. First, the statistical effect was studied by GLM and positive results have been used multiple comparisons by Tukey-B. It was found that on the basic colour has a highly significant influence line and family. Were examined influences on 4 basic body measurements (withers high tape, withers high rod, chest circumference, circumference of the cannon bone), where it was found that withers high tape, withers high rod, and chest circumference have a statistically significant effect of a family and line. The overall gain points is statistically highly significant influence lines and the number of ox 4th generation.

Presented diploma thesis deals with the issue of nutritional characteristics of the fish meat. Practical part is focused on the composition of rainbow trout meat originated from different rearing conditions. Samples for experimental evaluation were taken on June 14th-- 16th, 2014 from five fish-rearing facilities equipped with different rearing system. Ten rainbow trouts in marketable weight were taken from each facility to particular analysis. The fish were measured for length and weight characteristics from which the indices and indicators for condition and exterior evaluation were subsequently calculated. Also the yield and viscerosomatic index of fish were assessed. Biochemical composition of tissues, spectrum of fatty acids and sensory evaluation were assessed for the evaluation of nutritive value. The origin of fish was tested by genetic analysis. The best condition of rainbow trout was found out in flow-through system with short-time recirculation. The highest yield (almost 90%) was reached in fish with initial rearing in fish storage and consequent rearing in fishpond. Biochemical composition of muscle was significantly different mainly in the content of dry matter and fat. There was proved a mutual dependence between the content of dry matter and content of fat. The best results in sensory evaluation were reached in fish from flow-through system, the worst were reached in fish from recirculation facility. Genetic analysis recognised 4 homozygous haplotype and 1 heterozygous haplotype.

This diploma thesis examines the influence of air temperature on the behavior of fallow deer in farm kept. The literature review presents fallow deer characterization; it gives an overview of fallow deer management methods and describes the current situation in farming in the Czech Republic. The research part deals with observations of behavioral patterns of fallow deer. Every month in the course of a calendar year, a selected group of farmed fallow deer was observed all day, with special regard to their behavioral patterns concerning grazing, feed intake, standing or lying. Air temperature was measured every time. My research has shown a significant effect of air temperature on the behavior of fallow deer. Grazing was most prevalent in May (52 %), feed intake in January (39 %), lying in December (43 %) and standing in November (31 %). Moreover, spatial preferences of mineral deer-licks were examined in relation to feeding habits. The study has demonstrated that the location of a deer-lick has a considerable impact on its use. Fallow deer prefer significantly (75 %) a deer-lick close to a watering place rather than the deer-lick close to the border of the area. The results of the research were analysed in graphs and statistically evaluated by reference to Pearson's chi-squared test.

The thesis summarizes findings from the field of initial rearing of sterlet (Acipenser ruthenus) that are currently available. The results of experimental rearing, which took place in 2014 and consisted of two parts, are included. In the first part, the impact of the exchange rate of the water in the tanks on change of hydrochemical parameters. For the experiment three variants in duplicate were prepared, with different flow rate for each one. The volume of water in the tanks was set to 100 liters and the number of fish was 150 fish/tank. Water change rate within the first variant was set for 1/3 of volume per hour, within the second variant for 1/3 of volume per hour and within the third variant for 3/3 of volume per hour. Each day was measured oxygen content, water temperature and pH, and samples for laboratory analysis were being taken. The results were analyzed by analysis of variance. No statistically significant difference has been found between monitored parameters, therefore these flow rates had no impact on the change of hydrochemical parameters for each variant. In the second part of the experiment was compared the effect of three different feed mixtures on growth parameters and development of fish. The same conditions of the rearing environment were maintained, but stocking density was reduced to 50 fish/gutter and a uniform water change rate of 3/3 volume per hour was set. The first variant was presented feed Aller Bronze 2 mm, the second variant Aller Silver 2 mm and the third variant Biomar Inicio 918 2 mm. At the beginning of the experiment, the fish reached an average piece weight of 29.00 g and FWC 0.44 within the first variant, 29.70 g and FWC 0.43 within the second variant and 29.31 g and FWC 0.41 within the third variant. At the end of the experiment the fish reached monitored parameters with following values: the first variant had the average piece weight of 37.99 g, FWC 0.41, SWGR 0.90 %.d-1, FCR 2.12 kg.kg-1 and PER 1,01; within the second variant, the average piece weight was 40.38 g, FWC 0.41, SWGR 1.02 %.d-1, FCR 1.82 kg.kg-1 and PER 1.18; within the third variant, the average piece weight was 43.51 g, FWC 0.40, SWGR 1.44 %.d-1, FCR 1.44 kg.kg-1 and PER 1.46.
