Apoptóza mononukleárnych buniek a makrofágov mliečnej žľázy hovädzieho dobytka
Bátik, Andrej
This bachelor thesis is aimed on apoptosis of mononuclear cells and macrophages in bovine mammary gland. The first part is about mononuclear cells. Monocytes can quickly migrate from blood to tissue and differentiate to macrophages. Macrophages are professional phagocytes. They have significant role in immunity respond. These cells react on every antigen and they remove source of this antigen and also remove old and unuseful cells. Next part is about apoptosis. Apoptosis as known as programed cell death. In this part is described morphology, biochemistry and genetics of programed cell death. Apoptosis is completely natural way of dying, without it live cannot exist. Bovine mammary gland is often attacked by staphylococcus and other bacteria. Result of these attacks is in most cases mastitis, inflammatory disease. Mastitis causes serious health danger for cows also causes economical and finance lost in dairy farms. Thesis describes understanding of these processes in order to improve knowledge and battle against inflammatory diseases.

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.
