NĚMCOVÁ, Helena
The bachelor thesis deals with the occurrence and development of rumen microorganisms in the foregut of sheep with a focus on rumen protozoa. A literature review provides an introduction to the function of ruminal digestion in ruminants, covering foregut morphology and function and rumen fermentation. The practical part focuses on the collection of rumen fluid samples in sheep by the per os method, which were then sensory, chemically and microbially examined and the results compared with reference parameters.
In vitro experiments observing rumen degradation of non-saturated fatty acids in oilseeds
KUBELKOVÁ, Petra
PhD. Thesis are structured into two parts - first is comparison of effect of 4 seeds (amaranth, rapeseeds, sunflowerseeds and linseeds) on parametres of rumen fermentation and composition of fatty acids. Seeds were modified by milling, grinding or microwave heating.Findings of their effect on rumen fermentation were compared by control diet without seeds. The second part was specialised on effect of different amount of concentrate and forage in diet on fermentation parametres and amount of fatty acids. Diets were composed by barley and hay and then 3 diets for lactating cows were observed. Experiments were made on RUSITEC, which was apparature simulating environment in rumen of ruminants.
