Vliv parametrů mléčné užitkovosti na obsah somatických buněk v mléce u dojnic holštýnského skotu
Střítežská, Andrea
The aim of this work was to determine the effect of milk performance parameters that affect the number of somatic cells in milk in dairy cos holstein cattle. The work was carried out in the Czech Republic on a dairy farm in 2017 from January to December. Parameters included performance, phase lactation, the order of lactation, milk fat content, milk protein content, number of somatic cells. The information was obtained with performance monitoring and self-measuring of ingredients in milk from dairy cows over 305 days of lactation. In total, data from 3 061 dairy cows were processed. The following can be observed for the effect of milk performance parameters on the number of somatic cells. The order of lactation had a highly potent effect (p < 0.01), the younger cows (on the first lactation) had a lower number of somatic cells, with an increasing number of lactating somatic cell counts increasing. The lactation phase had a prominent effect on the number of somatic cells (p < 0.05), the trend showing an increasing tendency with increasing days in lactation. The fertility had a highly potent effect (p < 0.01), when the lower number of somatic cells had dairy cows with higher milk yields, while the higher number of somatic cells was at lower milk yield. The fat and protein content was statistically inconclusive (p > 0.05).

Přirozené partnerství člověka a koně
Střítežská, Andrea
This thesis deals with the natural partnership of man and horse. Introduction is focused on the horse's ability to communicate, which describes the vision and hearing. The second chapter describes the types of horses communications between themselves and their hierarchy. Horses communicate by touch, sound, smell and visual communication. Another part of the thesis is focused on interspecies communication, which is meant communication between man and horse. The man with the horse communicates with body language and vocal expression. The following are Seven games, which are the basis Parelli training program. The last part is focused on the method of Join-Up, which first began to apply Monty Roberts.
