Signs and causes of stereotypy, stress and depression in animals
Hášová, Tereza ; Landová, Eva (advisor) ; Sedláček, František (referee)
The chronic stress is caused by different, longer period of time acting stressors, such as sub-optimal living conditions, social stress or long-term changes of abiotic factors. Abnormal behavior during stereotyping and depression is caused by chronic stress, genetic factors and personality of the animal. Proactive animal is coping with stress by repetitive activity. In contrast, an animals depression is suspended by reactive personality and shows lack of interest and apathy to the stimulus. In animals in captivity after prolonged exposure to stress there are different types of stereotypic behavior depending on their natural way of life and their main activities. The effect on abnormal behavior has ontogenesis (including genetic factors, prenatal stress and the impact of personality) and early life experiences. Key words: Stress, stereotypy, depression, coping, proactive personality, reactive personality

The assessment of equine housing systems in terms of welfare
Morávková, Kateřina ; Hofmanová, Barbora (advisor) ; Majzlík, Ivan (referee)
Nowadays, the conditions of animals' breeding are better than they were in the past and bigger emphasis i sput on their compliance and improvement. To secure/provide a good welfare is not an easy task for the breeders. Generally, we know how good welfare should look like, but we do not know, if the animal is satisfied. Various studies and experiments of good and bad life conditions appear. On the other hand, there still are lots of things about the welfare topics, which could be discovered and explored. Other question is, if a bad welfare has something common with animals' cruelty, or does not. One of categories, which is welfare focused on is stablig. When horse breeding and stabling, we should consider their native lifestyle and behaviour. We should do this, if we want to secure a good welfare. In many of cases there is a problem, because as it has been said, there is no strict rule, what is a good and bad welfare. Some horses can be satisfied in a box, and the other can feel bad in the box -- they can have depression and they will feel best when they are out with other horses. Every system and style of stabling has its pluses and minuses. Some of the systems seem to be less suitable for horses, but it depends on the horses' character. But horses do not chooses their kind of stabling, it is choosen by the breeder. The stabling has been solved for centuries, and it must have been solved in the past, it is in the peresent, and it will be in the future. But we still come with new and improved ways of stabling. A modern guy can not imagine, that nowadays stabling should be the same as it was in the past. Today, we do not know, if this way of stabling was found as a good type of welfare and if horses were satisfied with it. It is a question, if better welfare is a box stabling or a styling out. For working horses the best stabling is the lashing one, where horses work in a wood and they want a lot of relax -- through this kind of stabling the rest can be enabled. But according to the law foals can not be roped. To stable the horse with the rope for 22 is a breach of a welfare. So we must alway take the reasons of stabling into consideration and if an exgerrated care about stabling does not verge on a horse's satisfaction. Through the behaviour and understading the horses a guy should be able to recognize, if the horse is fully satisfied and the welfare is arranged in the best way. It should be a reward for the breeders, if the horse has the good lifestyle.
