Králová, Marie
This thesis deals with reproduction, production characteristics and individual factors that affect the functional physiognomies of pigs. The first section describes the reproductive characteristics of sows and boars. Furthermore, the production and properties of the internal and external factors. Among the internal factors that include or comprises: hereditary characteristics, breed, hormonal activity, and gender, etc. External factors as: temperature, housing, nutrition, technology and feeding technology. The next section describes the family farm in Stavěšice dealing with the pigs. It is technology and technique of breeding, feeding, economic evaluation and profitability. In conclusion, the described economy pig in current conventional breeding.
Measurement and evaluation of exhaust gas production in the selected pig breeding with using techniques to reduce them.
KALINA, Vladimír
Agriculture plays a very important position in influencing the environment. It affects all three parts of - the atmosphere, hydrosphere and pedosphere. The aim of this work was measure the concentration - ammonia, carbon dioxide, nitrous oxide, methane and water vapor, with the help fotoacustic device INNOVA 1412 in Delacon center Stošíkovice na Louce. Measure was carried out in pig breeding. In this paper I will examine three additives in feed mixtures to reduce quality concentration of gases.
Complex evaluation of the best available techniques in selected company with pig farming and evaluation their economic impacts.
LHOTKA, Pavel
Thesis deals with complex evaluation of BAT techniques and their economic impacts in agricultural company Lihotošť which makes business in fattening pigs. Breeding of pigs is as well as the stud of other agricultural animals a producer of waste. In the European Union of production must be restricted gas emissions to a minimum. This range using the best available techniques (BAT), which help to reduce ammonia and greenhouse gases in the stable environment, landfill sites and in the application of slurry. The first part focuses on familiarizing with BAT techniques for pigs breeding. The next part deals with techniques applied in stud of pigs and their evaluation according to BREF. The third part is concentrated on evaluation of economic impact of applied BAT techniqueson monitored operation.
Greenhouse gasses emission load within animal production
LAŠTŮVKOVÁ, Jana
This thesis deals with a quantity of CO2 emissions produced during breeding of pigs. Two systems of farming (conventional and organic) were compared between each other. With help of questionnaire survey the data were obtained ? they were needed for a calculation of CO2 emissions in software program SIMA PRO which calculates emissions produced in agricultural phase: the breeding of animal from its birth to the end of fattening and converts them into CO2 equivalent. The aim of this work was to find out, which system of farming produces more CO2 emissions.
The spread of noise from building where the breeding pigs are kept into surrounding enviroment.
VÁVRA, Michal
This thesis deals with the evaluation of noise pollution caused by the operation of pig farm in the village Ponedrazka. The aim of this study was to measure noise at predetermined locations, its evaluation and comparison with the current legislative notice. Measurements were carried out during the vegetation growing season as well as during non vegetation season.
The evaluation of pig fattening at the farm school in Měšice
BONTEA, Petra
The aim of this thesis was to evaluate the pig fattening at the school farm in Měšice. The work is concern with the evaluation of the fattening period, the production and realization price of the pigs. The monitoring was conducted from 2010 to 2011. The evaluation included a total of 1994 pigs. The thesis take into consideration not only the initial and final weight of the animals, the losses, duration of the fattening period and the average slaughter weight, but also the total costs of their fattening. The statistical analysis was performed using Microsoft Excel. To evaluate the results the monitored indicators were calculated as average values and differences between data. When taken into the pre?fattening in 2010 the average weight reached 5.10 kg per piglet. In 2011 this figure dropped to 5.05 kg. The average weight of pigs sold in 2010 was 107.35 kg. It declined in 2011 to 101.27 kg. In 2010 the school farm in Měšice achieved an average daily weight gain of 0.67 kg. This number increased in 2011 to 0.74 kg. The average fattening cost per pig/day, during the reporting period in 2010, was 26.07 CZK. There was an increase the following year by 0.89 CZK to the amount of 26.96 CZK. When selling the pork meat in 2010, the average realized price by the farm was 26.46 CZK/kg. In 2011, the average realized price rose by 2.35 CZK / kg, thus increased to CZK 28.81CZK/kg Considering all the indicators and the production costs of the pig meat, the farm encountered a loss for the entire reporting period.
