Kontrola výživy, metabolismu a zdraví dojnic
Bednářová, Vladana
The bachelor thesis Inspection of Nutrition, Metabolism and Health of Dairy Cows is divided into a theoretical and a practical part. The theoretical part includes a summarising of basic options for a nutrition, metabolism and health inspection of dairy cows based on the study of the professional experience literature. This part includes the principles of the nutrition of the high-yield dairy cows and an introduction of the principles of production and preventive medical care (Herd Health Management) in dairy farming. Within the options of the nutrition, metabolism and health supervision there are presented subjective and objective methods that are used to detect deficiencies and nutrition and health disorders in practical farming conditions. These methods include a structure assessment of feed rations, ratings of BCS (body condition scoring), a rumen content evaluation, a rumination, an excrement consistency and a locomotion score of cows. Furthermore, there are presented the possibilities of the result using according to examinations of pool and individual cow milk samples. The practical part of the thesis contains a summary of assessments of the specific farm using by above mentioned methods.
Různé strategie terapie a prevence mastitid dojnic

This theses verifies the efficiency of a preventive (antimastitis) plan for a specific farm and the efficiency of the therapeutic protocol used for dairy cows infected by Staphylococcus aureus during dry stand. The introduction of this theses sets of the overview of methods of prevention of the mastitis and its treatment including the influence at the mammary gland of high productivity dairy cows. In the practical part the comparison of milk samples from the year before the preventive plan came into an action and the year after the start of the preventive plan has been made. Further the efficiency of chosen therapy has been made. This theses compares milk components of individual dairy cows (fat, proteins, somatic cells count and lactose) during the period, when cows has been evidently infected by Staphylococcus aureus and during the period when there has been no evidence of Staphylococcus aureus pathogen. Using the mentioned comparison, there has been observed the affectability of milk components during the infection of mammary gland with Staphylococcus aureus. Then the milk components of treated cows has been compared to the milk components of healthy cows never infected by Staphylococcus aureus. This comparison has been made to decide if the yield of treated cows achieves the yield of healthy cows. Based on the evaluation of the examined data, the success rate of treatment was 88 %. The milk components affected by the pathogenic microorganism Staphylococcus aureus are mainly somatic cells and fat in milk. From pool samples and the comparison of meantioned milk performance indicators, it has been found that the preventive program has been successfully implemented and met expected results.
