Vliv zkrmování výlisků z technického konopí na senzorickou kvalitu masa brojlerových kuřat
Fernandová, Dominika
This thesis deals with the influence of hempseed cakes in feed mixtures on the sensory meat quality of broiler chickens. During the experiment broiler chickens were fed with feed mixtures containing 5 % and 15 % of hempseed cakes and compared with the control group deprived of hempseed cakes. The total carcass yield, carcass yield of breast and thigh muscle, the amount of dry matter, crude protein and fat were determined. The pH and color of meat were measured and at the end of this experiment sensory evaluation of breast and thigh muscle was performed. For most sensory descriptors statistically significant differences were not demonstrated. Sensory evaluation of breast muscle determined a statistically significant difference (P < 0,05) with descriptors of odour and fibrousness. Sensory evaluation of thigh muscle showed a statistically significant difference (P < 0,05) with descriptors of odour, color, fibrousness and flavour.

Možnosti využití zbytků po zpracování technického konopí Cannabis sativa ve výživě brojlerových kuřat
Kratochvílová, Lucie
The aim of this thesis was to evaluate the effects of addition of technical hemp (Cannabis sativa L.) on performance parameters of broiler chickens. A total of 105 broilers Ross 308 were divided into three groups. The groups were identified: Cannabis 5, Cannabis 15 and Control. Group Cannabis 5 was fed with 5 % hempseed cake in feed composition. Group of Cannabis 15 was fed with 15 % hempseed cake in feed composition. Group of Control was not fed with hempseed cake. As a response criterion was chosen weight gain, feed conversion, lean meat, carcass yield and blood liver enzymes concentration. In this thesis, we focus on assessing the impact of hempseed cakes on weight gain, feed conversion and the carcass yield. The increments in body weight were significant statistical differences (P < 0.05). Broilers fed with 15 % hempseed cake in feed composition grew slowly and had worse feed conversion. Carcass yield was not affected (P > 0.05) by content of hempseed cake in feed composition. Measured concentration of enzymes in groups was not affected by contents of hempseed cake.

Hodnocení výkrmu kuřat s využitím nášlapných vah
Bendeová, Tereza
The aim of the diploma thesis was to evaluate the data gained from a weighine-machine located right in the hall of the selected company. The weighine-machine together with thermometer and hygrometer measures the weight of chickens, numbers of chickens weighed, temperature, humidity and uniformity. The data acquired about the given batches are from September 2014 to March 2016 from both types of hybrids. The results show that hybrid ROSS 308 occurred more often above the growth curve, in summer months it had better daily weight gain and the highest uniformity. Hybrid COBB 500 had better increase in winter and its uniformity was higher in temporary and winter period. According to the correlation analysis, the fact was confirmed, that with the growing weight the number of chickens lowers. The average mortality was around 3 %, the exception was the batch 6/2015 when the mortality was 4,8 %.

MMěření emisí tuhých znečišťujících látek v intenzivních chovech drůbeže
ŠONKA, Jan
There is a large number of contaminants in the air coming from agricultural activities that affects our environment. One of the major producers of contaminants is caused by poultry farming. These agents can be called a carbon dioxide, carbon monoxide, ammonia, hydrogen sulfide and dust. The aim of this thesis is to determine the value of PM10 concentration in poultry farming. These particles can damage not only animals' health but also the one of farm staff, because they are able to get behind the respiratory tract. Measurements were carried out in a poultry farm in Sudoměřice u Bechyně according to valid methodology by measuring the emissions of dust particles in poultry for the integrated pollution prevention and control. The device used for measuring purposes was DUST TRAK 8530 II. The resulting values were compared with the ones that are listed in table 5.15 on page 157 of the document Final TWG meeting for review of the IRPP BREF.

Realization of farm with a focus on poultry
Hromjak, Milan ; Zita, Lukáš (advisor) ; Kovářová, Kateřina (referee)
This thesis deals with the origin of a family farm. By creating a business plan and issues connected with it, its priority is an organic poultry farm, which will produce poultry meat and eggs. Another service beyond the farm production will be creating conditions for a developing branch, which is agro-tourism and other services related to the operation of the farm, so that it leads to the economic development and profit.
The farm will arise by rebuilding of an old house with a large barn and adjacent 10ha of lands inherited from grandparents. There will be built a multi-purpose building called the poultry farm from which the poultry will have access to pasture. The property includes another 1 ha of forest from which the wood will be used as a building material and firewood.
The work is divided into two parts: theoretical and practical. The theoretical part especially focuses on explaining the concepts that are important to understand the business plan.
Then there is the legislation concerning the organic farming, a tangle of laws, public notices and regulations that must be followed in order to meet the conditions for the organic farming. An integral motivational service of the country and the European Union for farmers and not only for those who are environmentally-managing farmers, is support and grants for the years 2014 - 2020. A very important step not only for the starting farmers is a market analysis in the given branch, as well as a SWOT analysis that will show us the positive and negative aspects of the business. The conclusion of this section deals not only with the concept of agro-tourism, but also with its market position as well and possibilities of its use and further development.
In the practical part there is a description of a business plan and individual periods of the project including financing. Finances will flow from own and foreign capital, or the possibility to apply for support through non-refundable grants. The establishment of the farm will have an impact on the labor market, as there will be 5 newly created jobs and the community will fit into the wider public awareness thanks to the activities that the farm will develop for the purpose of product promotion and further development. Furthermore, there are itemized individual items that lead to the final evaluation of the effectiveness of the business plan. By processing the theoretical and practical part of the thesis the requirement of the thesis objective is met - to design a prosperous family farm focused on poultry keeping with a hypothesis if it is currently possible to be competitive while importing poultry meat and eggs from abroad. It can be concluded that the business plan is viable.

The importance and use of sea buckthorn (Hippophae rhamnoides L.) in veterinary medicine
Lešnerová, Olga ; Lukešová, Daniela (advisor) ; Fernández Cusimamani, Eloy (referee)
Bachelors thesis mainly discussed the findings which are related to significance and potential utilization of the sea buckthorn (Hippophae rhamnoides L.) in veterinary medicine. We could appoint an antioxidant and immunomodulatory effects, positive effects on the cardiovascular system or treatment of skin diseases. Sea buckthorn could be also used in animal nutrition. For feeding purposes were mainly used leaves and residues after pressing juice and oils. The work also included informations about plant morphology, cultural management, harvesting, yield and processing. In a separate chapter were mentioned substances which were contained in various parts of the plant. Thanks to them, seabuckthorn is so familiar recently. Its potential is primarily in the use of bioactive substances in the field of medicine. In the last part of the thesis were created diagrams that showed quantity of selected substances contained in sea buckthorn fruits/juice and oils. For comparison were chosen vitamin C for fruits, vitamin E and carotenoids for oils within two subspecies H. rhamnoides L. subsp. rhamnoides and H. rhamnoides L. subsp. sinensis. The amount of extracted substances were often influenced by the used technology. In a detailed study and comparison of literature sources, it was found that for the subspecies H. rhamnoides L. subsp. rhamnoides literature indicates the quantity of vitamin C with a median of 229,5 mg/100 g, the content of vitamin E in the seed oil with a median of 351,8 mg/100 g and for pulp oil 147,5 mg/100 g. The carotenoid content in seed oil came with median 16,25 mg/100 g, for pulp oil it was 265 mg/100 g. Subspecies H. rhamnoides L. subsp. sinensis had the median value of vitamin C 1038 mg/100 g. For vitamin E in seed oil was the median value 119,3 mg/100 g, in pulp oil it was 171 mg/100 g. The median for carotenoids content in seed oil was 32,5 mg/100 g, the value for pulp oil was 282 mg/100 g. It will be necessary to ensure the subsequent research analysis about substances, especially in the field of veterinary medicine.

Emise tuhých znečišťujících látek v chovu drůbeže
JANOUŠEK, Tomáš
Agricultural activities produce a number of dangerous wastes affecting the environment. One is powder produced in livestock production, in particular in stables factory farms. Particulate emissions from livestock buildings are particularly important for the closest neighborhood stables. It is the subject of conflicts between farmers and their neighbors. The source of dust in livestock buildings are mainly food (fine particles modified cereals and dried plants) renegade animal skin particles, urine crystals and particles of feces. The aim of this work is to determine the concentration of dust in the factory farming of chickens for meat. Secondly, the aim is to compare BAT (Best Available Technique - Best Available Technology) technology used in stables with the reference document BREF (Integrated Pollution Prevention and Control - Integrated Pollution Prevention and Control). Measurements were carried out on a Farma U lesa in Sudoměřice u Bechyně on a poultry farm in Horní Miletín.
