Effect of probiotic feed additives on the funkcional status of the rumen

Popis výsledku v původním jazyce

In our study we have examined the influence of the probiotics Bifidobacterium sp. on the functional status of the cattle´s rumen. Two adult cows of Aberdeen-angus were used in this experiment. They were treated with a permanent cannula, which served for daily administration of probiotics Bifidobacterium sp.. Samples of rumen fluid were analysed for the amount of volatile fatty acids, protozoans, pH and 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 butyric and acetic acids were the variables best describing our data. The amount of protozoans increased as their levels grew. There is a strong effect of the individual as only two individuals were used. However, our results indicate that the influence of the probiotics Bifidobacterium sp., on the functional status of the rumen is low. These results could have been affected by the low number of experiment-replication as well as by a small quantity of tested animals.
