Návrh 3D modelu reálného ustájení drůbeže pro potřeby počítačových simulací
MÁTL, David
This diploma thesis focuses on the creation of a 3D model of real poultry housing, which will be used for the needs of computer simulations. The dimensions needed for the elaboration of the thesis, were measured in a real hall for poultry breeding. The model is created in free student version of computer 3D modeling program SolidWorks. In the research part of this thesis are introduced ammonia limit values and systems for their reduction in poultry housing. The next section describes Revolution 4.0 and how it relates to poultry housing. The following part deals with clever technologies used in agriculture and their connection with poultry farming. The practical part deals with the workflow of creating and building a model.
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.
Best Available Technologies for Intensive Livestock Production: Analysis of Present State in the Czech Republic
HAVELKA, Zbyněk
The thesis deals with the issue of the use of the best available technologies (BAT) in poultry and pig farms falling under the IPPC regime in the Czech Republic. The thesis presents an overview of the legislative framework of IPPC in the Czech Republic, an overview of the most important BATs. From the point of view of intensive poultry and pig farms, an overview of the number of facilities and their location in the Czech Republic, reported annual ammonia emissions and BAT used by these facilities is presented.
Doplňkové látky ve výživě drůbeže
PEKAŘOVÁ, Eliška
This bachleor work deals with the diference in digestion, necessary nutritiv and nutritiv additives for poultry. Feeding adittives are divaide into four groups zootechnical, technological, sensory and nutritive additives. Each group is described and individual types of additives and their use in nutrition are characterized. The work describes individual substances and their description and effect on health, production or feed.
Analysis of meat demand in the Czech Republic
Dlasková, Karolína ; Ščasný, Milan (advisor) ; Polák, Petr (referee)
Meat and meat products form the highest share of Czech household expenditures for food. This thesis offers a complex view on the Czech meat market and studies in detail the determinants of meat demand. A review of the most frequently used demand models is included, from which the least squares log-log model is used for empirical analysis. The core of this thesis is the estimation of price and income elasticities of demand for various types of meat based on statistical data of household accounts from the years 2000 - 2012. The estimates are, with the exception of the price elasticity for beef, which equals 0.13, consistent with previous studies. Within the examined period, households manifest unitary income elasticity and own price elasticity of demand for meat equal to -1.2. The temporal evolution of elasticities varies for different types of meat. Important socio-demographical aspects influencing the demand for meat, such as age, education, whether the household is led by a female, and others, are also analysed.
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...
The effect of gut microbiota composition on condition in birds
Černá, Kateřina ; Vinkler, Michal (advisor) ; Saláková, Martina (referee)
The aim of this thesis is to summarize present knowledge concerning the effects of gut microbiota composition on condition in birds. The effect of gut microbiota on various aspects of animal physiology is currently intensively studied and the understanding of its biomedical importance is a topical theme. However, the majority of the current research is focused on humans and other mammals, and in birds on agriculturally significant species. Therefore, this thesis focuses also on the applicability of results of agriculturally orientated research on free-living birds' study. The results of agricultural research show a high interspecies and intraspecies variability in the effects of certain bacteria on the condition of the host. That should be taken into account when designing experiments in wild-living species. This thesis summarizes current knowledge concerning the effects of bacteria on condition of birds that was gained in correlational and manipulative studies. Manipulative studies include those in which probiotics or antibiotics were given to birds. The main modes of action of probiotic bacteria are also summarized here. One of the aims of this thesis was also to find out the possibilities of using detection of certain bacterial species as a non-invasive method to assess birds' condition. This thesis...
Ptačí chřipka a její chovatelské důsledky
KOTRCOVÁ, Markéta
In the bachelor thesis on the bird flu and its breeding consequences is analyzed the current state of the disease situation of bird flu in the Czech Republic. The main goal was to find out the cause, overview, occurrence and impact of avian influenza on poultry farming.
Vyhodnocení výrobní měrné emise amoniaku z vybraného chovu drůbeže
PILÁT, Jiří
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.
