Persistence of bifidobacteria in the intestines of calves after administration in freeze-dried form or in fermented milk

Popis výsledku v původním jazyce

In order to improve the gut microbiome of calves, probiotic bacteria can be fed as active living-cells (fermented milk), or as live but inactive (freeze-dried) cultures. Ten bifidobacterial strains with suitable probiotic properties (as determined in our previous study) were tested for survival during the freeze-drying process, and screened for their ability to ferment cow's milk. The viability of both freeze-dried and live-cell cultures during storage was also tested. All of the strains tested were able to ferment cow's milk, with average counts of 8.26 +/- 0.62 log CFU/ml. Eight out of the ten strains were able to survive in milk for 2 months in counts higher than 10(6) CFU/ml. Bifidobacteria showed high viability following the freeze-drying process, with average numbers of 9.03 +/- 0.22 log CFU/vial and did not decrease after 12 months of storage. The mixture of rifampicin-resistant variants of bifidobacteria (RRBs) was fed to 2-day-old dairy Charolais calves in the form of living-cells, or as fre
