Selected fabric metabolism parameters of dairy cows
KAŇKA, Vladimír
The aim of this study was to evaluate antiketogenic prophylaxis of the veterinary medicine Kexxtone, in breeding of Holstein cows, in the company Agrodam Hořepník, s.r.o. There were then evaluated the parameters of a metabolic state in the herd monitored. Furthermore I evaluated the milk yield, amount of fats, proteins, lactose and somatic cells in the milk during 100 days of lactation and subsequently, the level of pregnancy after the 1st and the 2nd insemination was evaluated. The observation took place from July 2014 to December 2014 in a way that every two months was selected 8 cows and 8 heifers with a similar calving date. After that they were split into two groups i.e. into the experimental group (the kexxtone medicine was used) and into the control one. These cows were bled and milked. Subsequently, those biological samples were sent to a laboratory to be diagnosed. The higher milk yield was found within the experimental group and so as the content of milk constituents, i.e. fats and proteins. A beneficial effect of this antiketogenic medicine on the amount of ketones in blood and milk of animals was also confirmed within the experimental group. There were not found any significant statistical differences in other monitored parameters.
Metabolic profile of dairy cows in the selected breeding Holstein cattle

Výživa dojnic v období stání na sucho je pro zemědělce klíčovou částí při chovu dojného skotu. V tomto období je důležité zvolit optimální krmnou dávku, tak aby kryla záchovnou potřebu krávy i plodu a proto bylo cílem mé bakalářské práce zhodnocení účinku dvou odlišných způsobů krmení krav stojících na sucho, a to fázové výživy, jenž se běžně využívá a výživy na bázi jednotné krmné dávky po celou dobu stání na sucho, na vybrané ukazatele metabolického profilového testu, užitkovost v průběhu laktace a z ekonomického hlediska.
