Mléčná užitkovost holštýnského skotu
Zapletalová, Lenka
The bachelor thesis focuses on the milk yield of Holstein cattle. The aim of the thesis was to focus on the issue of milk yield and characteristics of the Holstein breed. The first part of the thesis describes problems related to the characteristics and composition of cow's milk and collagen, mammary gland (mammary gland growth and development, mammary gland physiology and anatomy), factors influencing dairy yield, milk performance evaluation and characteristics of the breed. The second part of the thesis focuses on the characteristics of the holding, the characteristics of the herd being studied and the evaluation of the dairy cow performance in Dubická agricultural joint-stock company. In conclusion, it has been found that milk performance has changed over the years. For the period 04/2016 - 03/2017 and 04/2017 - 03/2018, changes in the length of time, protein and fat content, fat and milk yields occurred. Of these indicators, the period has the greatest impact on milk production. In the lactation order, it has been found that increasing lactation rates increase milk yield in the amount of milk.
Environmental influences on the shape of ultraviolet signals in genus Gonepteryx (Lepidoptera, Pieridae).
Pecháček, Pavel ; Kleisner, Karel (advisor) ; Zapletalová, Lenka (referee) ; Vrabec, Vladimír (referee)
Like many other animals, butterflies are able to visually perceive the ultraviolet (UV) light; many species even have patterns on their wings which are visible in this part of the electromagnetic spectrum. Over the last forty years, it has been shown that these UV patterns play an important role in behaviour of many butterflies, especially in relation to sexual selection - they are involved in the process of recognising a suitable mate, and likely can signal some of the mate's qualities, such as its age, ability to handle stressful environmental factors, or efficiency in foraging. The patterns may also be used for taxonomical purposes. This dissertation thesis contains a comprehensive research into ultraviolet patterns of the Gonepteryx brimstones, with a primary focus on the issue of environmental influences in relation to the expression of these traits, on the patterns' potential role in sexual selection, or on their evolution. It has been successfully demonstrated that UV patterns of at least some Gonepteryx species are affected by the environment to a strong degree, significantly more than the traits not involved in sexual selection. On the whole, the conclusions made by submitted publications suggest that UV patterns play a role in the sexual selection of the chosen brimstones, though it is not clear...
Factors affecting the mental condition of seriously ill patients
Zapletalová, Lenka ; Žáčková, Hana (advisor) ; Cimrmannová, Tereza (referee)
The Bachelor thesis entitled - Factors affecting the mental condition of seriously ill patients describes an individual's mental coping ability and his fight against factors that are connected with serious illness and are significantly affecting his mental condition. The thesis brings information about important changes that affect the patient's perception about his serious diagnosis. This thesis counters the theories put forth by people who work with seriously ill patients. At the end of the thesis, I describe the selection of factors that fundamentally affect the patient's mental state and health condition which were elicited from the questions put forth in the interviews.
