Faktory ovlivňující welfare dojnic
Zavoralová, Lenka
The Bachelor thesis is developed on the topic of factors affecting the welfare of dairy cows. Its aim was to process a literary research focused on the ethology of dairy cows, welfare and factors influencing the walfare of dairy cows. As a part of the practical part two stables of one farm were monitored. All data for the practical part were obtained at the Zderaz Agricultural Farm. The company is engaged in the breeding of Simmental cattle. The behaviour of the cows was noted in the resting period in the stables, but also at the times with the occurrence of disruptive elements. Observations took place in the old and new stables in order to compare specific stables. Subsequent processing of the results revealed a higher number of lying dairy in the new stable during the day. The time of habit utilizing cows for a new parallel milking parlour was also monitored. After five days, the cows went to the milking parlour relatively alone. Lastly, the mastitis of cows was monitored. The highest number of mastitis was observed in summer July, August 2022.

Vyhodnocení životních projevů koní ve vztahu ke způsobu jejich využití a ustájení
Vurstová, Aneta
This bachelor thesis "Evaluation of life manifestations of horses in relation to the way of their use and housing" deals with the ethology of horses and how it affects the environ-ment in which horses live. In the first part of the literature review, the origin of horses is briefly described. The second part deals with basic life manifestations such as food behavior, excretion, rest, movement, sexual behavior and social behavior. The next part describes the horse's psyche and intelligence. The last part deals with abnormal behavior. The practical part was realized in the form of ethological observation. The influence of stabling and use of horses was evaluated. The experiment was conducted in the summer of 2022 in nine different stables. The most common manifestation, in all groups, was food intake. Another important manifestation was resting behavior, which manifested itself in all groups especially in the afternoon. The third most frequent manifestation was observation of the surroundings.

Cognitive and behavioral alterations in neurodevelopmental and pharmacological animal models of schizophrenia
Malenínská, Kristýna ; Stuchlík, Aleš (advisor) ; Blahna, Karel (referee) ; Telenský, Petr (referee)
Establishing reliable animal models of psychiatric diseases such as schizophrenia is essential to better understand the neurobiological, behavioural and genetic basis of the disorder and to develop new drugs with greater therapeutic efficacy. These models allow the study of different aspects of schizophrenia, including positive, negative and cognitive symptoms similar to schizophrenia. All available animal models of schizophrenia can be divided into four different categories of induction: developmental, pharmacological, genetic and lesion-induced. However, none of these models perfectly replicates all aspects of schizophrenia in humans, and it is therefore necessary to precisely define the influence of each manipulation. This thesis focuses on the study of pharmacological and developmental animal models of schizophrenia, with an emphasis on examining the cognitive and behavioral changes associated with the disorder. Specifically, we investigated the pharmacological induction of schizophrenia- like symptoms by acute administration of MK-801, developmental models of two interventions combining the maternal immune response following poly(I:C) administration and subsequent stress of offspring in adolescence, and repeated prenatal and neonatal administration of lipopolysaccharide (LPS). In the...

Stress markers and methodologies for their measurement in selected model species
Langmajerová, Anna ; Nekovářová, Tereza (advisor) ; Petrásek, Tomáš (referee)
The stress response is a cascade of physiological and subsequently behavioural processes that enable the organism to cope with various stressful situations and influences (stressors). The manifestations of stress in different organisms are to some extent similar, but at the same time they may differ in intensity and manner. Stress can be measured using biological markers, which are objective and measurable and indicative of underlying biological processes. This bachelor thesis focus on stress markers and the methodology of their measurement. It also discusses specific types of stress markers in each model, for example, measurement of stress hormones (cortisol, corticosteroid), measurement of body temperature, blood pressure or heart rate, or behavioural performance. The thesis also focus on the issue of suitability and applicability of various methods of measuring and evaluating stress in individual models, depending on their accuracy and welfare of the animals during a given measurement, which may influence the test results. Keywords: animal model, behavior, biomarker, stress

The effect of selected cannabinoids on quantitative EEG, behaviour, and their therapeutic potential
Uttl, Libor
Cannabinoids and especially CBD are these days a highly discussed topic with a huge overlap in the media space. Their ability to interact not only with cannabinoid receptors, but also with other pathways, in combination with a huge "hype", leads, despite the not very strong evidence of their effects in clinical practice, to the testing of cannabinoids in a broad spectrum of indications. Nowadays, we have more than 150 isolated cannabinoids, but the research is focused only on the main cannabinoids like for example THC, CBD, cannabigerol, cannabichromen or hexahydrocannabinol. For our research, we have chosen the two most well- known cannabinoids THC and CBD, and our key question was not only what is the role of these cannabinoids individually, but, also, how do they interact when administered together, how do they influence behaviour and how do they interact in dependence on the method of administration. All these questions were addressed within our rat experiments. Somewhat surprisingly, we did not observe the typical cannabinoid tetrad (decreased sensitivity to painful stimuli, hypothermia, catalepsy, and overall decrease in motor activity) after the THC administration, so we wondered what would happen if we used more potent and selective synthetic cannabinoids JWH- 073, JWH-210, instead of THC....

Vliv glyfosátu na fyziologické procesy v živočišném organismu
Jelínková, Lucie
This bachelor thesis deals with the effect of glyphosate on the animal organism. The influence of individual selected groups of animals and humans is examined in different types of expermients. The bees in the behavioral study showed a reduced response to sucrose, a deterioration in short-term memory and a deterioration in the formation of ofor-foos relationships. Glyphosate reduced biodiversity in the amphibian population and also halved the toxicity at lower doses when the active substance was studied. Glyphosate also affects carp hepatocytes, which are subject to histological changes. The deteriorating health of the fish, which is infested with exoparasites, makes it easier for glyphosate to enter the body. In rats and rabbits, they cause reproductive problems. Human placental cells respond to glyphosate by reducing the production of the enzyme responsible for estrogen synthesis and thus to fertility problems. Glyphosate is more common in professional exposure and i tis similar in the population living in the immediate vicinity of its application.
