The aim of the bachelor thesis was to perform practical monitoring of production indicators of broiler hybrid Cherry Valley SM3 in the Smilkov farm Ltd. The study was carried out in two breeds (Smilkov and Kouty) with different fattening technology for the period of 1 year. The weighing always included 1 % of the total number of ducks of the monitored batch, i.e., 32 ducks. The results were obtained from 14 batches (7 batches from each barn). The highest live weight was achieved in the Smilkov breed, with an average of 3.52 kg/pcs, while the Kouty breed achieved an average weight of 3.45 kg/pcs. The Smilkov breed also achieved a better average daily gain, which was 83.3 g/head/day, the Kouty breed had a lower average daily gain of 81.5 g/head/day. The Kouty stable, which has a controlled microclimate, showed better results in mortality rate and feed consumption. The average mortality rate was 1.64 % and 153.3 t of complete feed mixture were fed during the period under review. The average mortality rate in the Smilkov farm was 2.87 % and 165.1 t complete feed mixture was consumed, a difference of 11.8 t of feed between the farms. The feed conversion ratio (amount of feed needed per 1 kg of gain) in the Kouty farm was 2.2 kg/1 kg of gain, while in the Smilkov farm the conversion was found to be 2.3 kg/1 kg of gain.

Space-time continuum links of announcements about deaths and injuries of birds in rescue stations in the Czech Republic.
HROMÁDKO, David
Birds represent the most frequent group of patients that rescue centers take care of. Road transport, glass panels, electric lines and poaching are main risk factors for birds in anthropogenic landscape. Thanks to rescue centers, many injured or endangered birds are cured and released into the wild every year. That is why rescue centers play an important role not only in environment protection but also in ecological education. This dissertation interprets causes of admisssions of birds wounded by anthropogenic lanscape. In this work I processed the databases of animal rescue centers during the period from 2008 to 2017. Those databases contained composition of the species, age, causes of admissions and follow-ups of injured birds within that period. Circumstances leading to admissions were also investigated from perspective or particular birds orders and their species composition. I also analysed links between sensitivity of birds orders towards impact of human activities on the environment together with quantity progress of admissions in particular years and in particular orders of birds. I also evaluated seasonal variation in number of admissions and relevance of birds age in regards to their injuries. Types of the injuries and zoological classification were also assessed. Most frequently rescue centers took care of birds from the order of passerines (Passeriformes). All in all, synanthropic species appear to be most vulnerable, which is significantly related to anthropogenic impact on the environment. In regards to age category non-independent juveniles were the ones who needed medical treatment most frequently.

Zhodnocení potřebnosti a využití loveckých psů v současné myslivecké praxi
Dufková, Soňa
Thesis is concerned with the topic of evaluation the usefulness and utilitysation of hunting dogs in the current conditions of hunting practise. The goal of thesis is to collect data about the practise; how are hunting dogs used in the hunting locations, how are legislative measures and those of use of huntings dogs kept, during the hunting together and in the hunting locations as well. Then the thesis finds out which under which certain circumstensis the injuries, deaths and moratlity of huntings dogs are the most probable to occur. The fullfilment of the thesis goal is considered to bet he application of its findings into the common practise, as for to improve the protection elements of the measures for huntings dogs. To obtain the neccessary data for the analysis the questionnaire method was used. The analysis then was concerend with the legislation in the Slovak republic and in the Austria and after the acknowledgement of the differences and similarities the results was compared with the legislation of Czech Republic. The final phase is to evaluate the porcessed data and propose direct effective outputs for the practise.

Analýza hlavních vlivů působících na tržní produkci masných krav velkého tělesného rámce
Pešová, Nikola
This thesis is focused on the analysis of the main factors influencing beef cattle of huge body frame. Main observed factors were the number of cows kept, the number of born calves, mortality and adverse selection. The herd turnover was observed in 2013 on the eco-farm Ost West Agro, s.r.o. in Detrichov nad Bystrici. Further, the takings for carcass and lot animals in different weight categories were estimated. The thesis also includes cost summary of animal staying on pasture and in winter site. After evaluating the factors, it was discovered that the biggest commercial revenues for beef cattle business production represents the born calve. Estimation for sale of carcass and lot heads was in total 1 720 148,80 CZK. The biggest part comprised discarded cows, in total 874 073 CZK. The second biggest part comprised the lot bulls and heifers with weight under the 240 kg, in total 378 681,60 CZK. The next item represented lot calves, for those the business took in 257 777,50 CZK and the lowest income was for heifers from 1 to 2 years, in total 209 615,70 CZK. The difference discovered between the amount of costs in winter and summer time was at least three times higher.

Evaluation of two different types of apparatus for producing electrolytically treated water and their effect on zootechnical parameters.
ŠVEC, Miroslav
Working with the theoretical part of the first looks at ways of fattening broiler chickens kept for meat production. The following are selected chapters technology intensive fattening of broiler focused on breeding on litter technology. Work in this section also addresses microclimate conditions and zootechnical indicators. At the end of the theoretical part introduces electrolytically treated water, the principle of its production, its advantages and applications. In the practical part of the work introduces with company TAGREA Ltd. in Čekanice near Tábor, which serves as a farm for intensive fattening chickens on litter technology and where has also been evaluated two different types of apparatus for producing electrolytically treated water, specifically device Envirolyte and apparatus e-Dison. This part continues characteristic of these types of devices, says their technology, specifications and advantages. The following is a graphic design and compare the results of seven courses of using one or other of type of device. The theoretical part this works ends an evaluation of these results and the conclusion.

Effect of transport stress on the mortality of broilers
SEDLÁČKOVÁ, Renata
The aim of the thesis is to acquaint the reader with the reasons for mortality of broilers during their transport to the slaughterhouse. Materials for your own research (from 2012) were obtained from the State Veterinary Administration of a company Vodňanská drůbež s. r. o., the argest supplier of poultry meat in the Czech Republic. The second chapter deals with legislation relating to animals in general, but also legislation that governs the protection primarily for meat production. Welfare of broilers, therefore, their comfort, and handling is dealt with in the third chapter. It describes picking halls, catching chickens, chicken waste, transport of poultry for slaughter, chickens and unloading conditions to be met by the authorized person when handling poultry. The fourth chapter describes the factors affecting the welfare of broiler chickens during fattening. These factors include the type of litter, microclimate - thermoregulation poultry, lighting, and health status of broilers. Because the work deals with the mortality of broilers during transport, the fifth chapter is devoted to this issue. There are analyzed transport requirements, the effect of high and low temperature for transporting poultry. Furthermore, means of transport and the obligation of carriers during transport to the slaughterhouse, whether it's planning a trip or taking care of animals during transport. The sixth chapter deals with the custom dissertation: In 2012, it was the slaughterhouses (company Vodňanská drůbež s. r. o.) moved from 116 breeders 30,231,410 pieces of broilers at slaughter, of which 136,616 units during transport died at a mean of 0.455 %. Most deaths were at a distance of 251-305 km (0.834 %), at least at a distance of 50 km to 0.252 %. Age of chickens at slaughter, an average of 35.13 days and slaughter weight was on average 1.93 kg. Most deaths occurred during transport of broilers during the winter 0.919 %, the correlation coefficient r = 0.37, less than 0.316 % in summer (r = 0.02).
