Influence of Probiotic Feed Additives on Rumen Microflora of Cattle

Feed digestibility is very important for milk production. This is related to the functional status of rumen, which is influenced mainly by the amount of feed intake and its quality. The aim of the study was to determine how probiotic supplements affect rumen microflora in cannulated cows. Feed supplements were given to cannulated cows in the experimental stable and changes in the number of microorganisms in the rumen were monitored. They were found positive trends in the growing number of protozoa in the rumen, but not statistically significant effect of probiotics on the development of the rumen microflora (P > 0.05).
