Vliv probiotických krmných aditiv na funkční stav bachoru
HADAČOVÁ, Veronika
In my study I was examining the influence of the probiotic Bifidobacterium sp. on the functional status of the cattle´s rumen. Two adult cows Aberdeen-angus were used in this experiment. They were treated with a permanent cannula, which served for daily dosing of probiotics Bifidobacterium sp.. Samples of rumen fluid were analyzed for the amount of volatile fatty acids, protozoans, pH and the quantity of ammonia. When we tested the effect of the probiotics on each variable, the fixed effect of the influence of an individual has not been proved. When we tested the data without the effect of the individual in a linear model, the variables best describing my data were the butyric and acetic acids. The amount of protozoans increased as there levels grew. There is a strong effect of the individual as only two individuals were used. My results indicate that the influence of the probiotics Bifidobacterium sp., on the functional status of the rumen is low. These results could be affected by the low number of experiment-replication as well as by small quantity of tested animals.
