This thesis concerns enumerating household waste components. First section of the thesis describes informational and legal background of waste management in the Czech Republic. There is also information on European legislation on waste management. Methodology of getting data from my own measuring is described in the second (applicative) section. Amount and structure of waste produced by one household of four members was measured for one year. During the week the waste was sorted into separate bins according to its type (biodegradable waste, municipal solid waste, plastics, PET plastics, paper, liquid packaging boards, metal, white glass, coloured glass and hazardous waste). Measuring took place in week intervals and values were recorded in a chart. Those data were evaluated and compared with Ing. Kotyzová's thesis. Another part of the second section aimed at data evaluation of waste production in Valašské Meziříčí. This was compared with my own measuring. The last part focuses on comparation of Valašské Meziříčí's waste production, ČSÚ's data and my own measuring.

ABSTRACT This diploma thesis deals with evaluation of the waste management system in Kroměříž. The introductory part is devoted to the legislative regulations related to the issue of waste generated in the given town. Furthermore, the thesis deals with the overall waste production in the Czech Republic and the Zlín Region. The practical part focuses on the waste management in Kroměříž compared with Vsetín and the Zlín region. The resulting data was processed using basic descriptive statistics. The results are compared with the waste production in Kroměříž in relation to values per capita within the Czech Republic, Zlín Region and Vsetín. In the concluding part of the thesis, an evaluation of achieved results and a proposal for possible improvement measures in waste management in Kroměříž are presented.

The aim of the work was to obtain data on performance and milk composition from performance control and to compare these results between a group of cows with diseases of the hoofs and healthy cows. The hypothesis has been verified as to whether the performance and composition of dairy milk is influenced by the occurrence diseases of the hoofs. Surprisingly, according to the results of this work, the influence of the studied diseases on the monitored parameters is relatively small. Proportional reduction in cow milking was confirmed only in one experimental group (reduction in milking for 3.38 liters, P <0.01). The affect on the results is probably also the fact, that the latent measure was not detected in the animals, but only the presence of problem hoof. The occurrence of limping (as a sign of pain) will probably influence the decrease in milking much more than individual finger diseases that are not painful enough to cause limping. Furthermore, the statistical significance of the increase in somatic cell counts (an increase of 67,000 SB / 1ml, P <0.05) in one monitored group of diseased dairy cows was demonstrated. However, the increase in the number of somatic cells may be caused by a number of other factors. Other studied milk composition parameters (fat, protein, lactose, ketone, urea, free fatty acids) were not significantly different between groups. On the basis of the evaluation and experience from the implementation of the study, the degree of limping of the cows would be considered as a factor for continuing research in the area.

The aim of this thesis was to monitor and evaluate the impact of internal factors on the production and quality of milk in a herd of montbeliarde cattle. The hypothesis was that worse results of reproduction adversely affect milk production. Data collection took place on a farm Osičky agricultural company Agrodružstvo Lhota pod Libčany for the period from 1.1.2010 to 31.12.2015. The file was obtained 1 849 standard lactations completed in this period. The source of data for evaluation of milk production, milk quality and reproductive performance of cows were cards, program Farmsoft from Farmtec used to herd management and output data from the inspections carried out by the utility Chovservis Inc. residing in Hradec Kralove. A statistically highly significant difference (P<0,01) between the first and all other amounts lactation in milk, fat and protein kg per lactation and fat in % and between 1st and 5th and more lactations in % protein. Was a positive effect of length of service period and the length of the intervening period the quantity of milk, fat and protein in kg per lactation at significance level P<0,001 and the negative influence of the length meantime to protein content in % (P<0,001). He was also found at least P<0,001 positive effect on lactation length produced kilograms of milk, fat and protein. Fat and protein also positively influenced the amount of milked milk (P<0,001). It was statistically insignificant effect on the incidence of mastitis production and milk quality (P>0,05), based on correlations may have an adverse effect on the percentage of fat and protein at a higher incidence of mastitis expected. The influence of the proportion of blood Montbeliarde breed was statistically proven only on the amount of milk and protein in kg per lactation, but still pure-bred animals came out the best in all of the indicators except for milk production fat percentage. From comparison of the calving showed that his herd performance increases every year, the quality of milk as the fat content in % but conversely decreases. For the month of calving has been shown to influence the percentage of fat and protein at a significance level of P<0,001, the quantity of milked milk (P<0,01) and the amount of produced protein in kg per lactation (P<0,05). The hypothesis that impaired reproduction results negatively affecting milk production has not been confirmed. It was found to influence reproduction indicators on production and quality of milk, but this influence in a positive direction. The negative effect was demonstrated only for the length of the interim influence on protein content in %. Overall, the level of flock assessed as very good, but there are many indicators of production and reproduction that is necessary with respect to the potential of improving the breed.

ABSTRACT The aim of the thesis was to evaulate and analysis of changes in the amount and composition of cow milk from Holstein dairy cows caused by prolonged lactation.The necessary information regarding the composition of cow's milk and a more detailed description of the milk components (fat, protein, somatic cell, lactose, urea) are included in the literature review. Samples were obtained from Holstein dairy cows from Unčovice Farm and used in our analysis. The samples were collected in the annual period from 7. 3. 2018 to 7. 3. 2019. The sampling was carried out by trained staff from the performance control and number of dairy cows involved in the analysis was 4540 units. The samples were taken for studied parameters (daily milk yield, fat content, protein content, lactose content, urea content and somatic cell count). The results show a large effect of lactation days on daily milk yield and and the content of milk components. Also, the daily milk yield is correlated with the content of milk components. The established results also show the effect of lactation on somatic cell counts but the effect of lactation on the urea content was not found. Furthermore, it was evaluated the frequency of mastitis.
