Diploma thesis deals with consumer behaviour of young people concretely graduates of tertiary education on the labour market. It focuses on identifying the factors that influence graduates during their studies and describes their decision making process. In order to determine consumer behaviour quantitative and qualitative methods were used. Electronic questionnaire survey as quantitative method was held since November 2013 until March 2014 and in total 651 respondents participated. Interviews as qualitative method were carried out with 30 respondents. All the results were used for the compilation of the model of consumer behaviour and for giving recommendations for subjects who are involved in this issue.

Ethical issues in livestock breeding have been in focus of public interest recently. A strong attention is paid to living space, ability to express natural behaviour, and good care of animals known as welfare. Presented thesis aims in evaluation of animal welfare indicators on 20 farms with organic dairy production using the methodology of Welfare Quality (WQ). The following criteria were assessed: absence of prolonged hunger and thirst, comfort around resting, ease of movement, absence of injuries, disease, and pain induced by management procedures, expression of social and other behaviours, human-animal relationship, and emotional state. These criteria are combined into four basic principles: good feeding, good housing, good health, and appropriate behaviour. Principal attention is paid to the relationship between animal welfare and health. Most farms showed high scoring of good feeding including the proportion of very lean cows and sufficient water supply. Good housing got also high evaluation, because the organic farming standards require loose housing and majority of time spent grazing on pastures. Lower scoring of good health was caused by dehorning on a part of farms, which decreases the absence of injuries evaluation. Farms had mostly low proportion of lame cows, cows with lesions and hairless patches, and cows with discharges and diarrhoea; no cow had mastitis. No expression of agonistic behaviour was recorded, the scoring of human-animal relationship and positive emotional state was fairly good, too. Obtained scores were generally higher compared to results from conventional farms published in literature. All farms were evaluated as enhanced or excellent. Larger herds had generally lower scoring of human-animal relationship, but higher scoring of positive emotional state. Farms with dehorned animals exhibited lower proportion of very lean cows and nasal discharge. A higher percentage of lame cows was found on farms with worse cleanliness compared to farms with cleaner conditions. Proportion of lame cows correlated with the proportion of very lean cows, and together with the proportion of cows with integument alterations it was influenced by the comfort around resting. It was confirmed that good conditions of cow breeding and good welfare lead to better health and behaviour of animals. Organic farming creates favourable conditions for good animal health and welfare. The output of the thesis provides farmers an evaluation of animal welfare on their farms and a comparison with other farms.

This thesis is focused on evaluation of welfare quality in dairy cows at 10 farms (factory farming) in the Czech Republic. Studies concerned with this topic are showing that the quality of welfare and the farm environment has a significant influence on their efficiency. Welfare evaluation in this thesis was done in accordance to European project Welfare Quality. In processing of this thesis was evaluated ten of totally twelve criterions; absence of prolonged hunger and thirst, comfort around resting, ease of movement, absence of injuries, diseases and painful procedures, expression social and other behaviours, and good human animal relationship. From four principles based on criterions above, i.e. good feeding, good housing, good health and appropriate behaviour, were only three evaluated. Most of the farms had a low scoring of good feeding including part of very lean cows and bad access to the water. Favourable was evaluation of good housing, because 60% of farms had above-standard results. Lower evaluation was in the principle of good health due to dehorning on all monitored farms. Czech farms had significantly higher percent of very lean cows comparing to foreign breeds. Lameness in the Czech Republic was different in comparison with foreign studies. Small part of cows suffering of discharge, cough, or hampered respiration was detected. Number of animals suffering from diarrhoea is comparable to foreign studies. Expression of agonistic behaviour was minimal in monitored farms. That is displayed in excellent evaluation of criteria expression of social behaviour. Almost all farms had acceptable evaluation of good human animal relationship. Hypothesis, that in farms with lower quality of environment is higher percentage of cows that hobble, than in farms with better quality of environment, was not confirmed. Another hypothesis was partly confirmed. The farms with higher percentage of cows with health issues struggle with problems during the rest time, than the farm with lower percentage of cows with health issues. Part of cows that lameness correlate with part of cows with patches and part of very lean cows is affiliated to part of cows with diarrhoea. Welfare quality in monitored herds, were at an acceptable level. Most need to improve the area of good feeding, but for accurate results it would be appropriate to evaluate a greater number of farms.
