Selection of probiotic bifidobacteria for lambs.
Original language description
Twenty-six bifidobacteria were isolated from faecal samples of lambs. Isolates were identified, functional properties (survival ability in low pH and bile condition) and antimicrobial activity against potential pathogens were determined. From isolates with suitable properties (13 strains) rifampicin-resistant mutants were prepared by gradient plate techniques. This property enabled us to differentiate the organism administrated from wild strains, because resistance to rifampicin is rare among bifidobacteria. A rifampicin-resistant bifidobacteria (RRBifs) were administrated to 3-day old lambs in two trials. In the first trial strain B. ruminantium L29 was applied to 3 lambs and was detected in faecal samples in high counts (6 log CFU/g in average) for one week. In the second trial 3 lambs were fed with ?cocktail? of 12 strains and RRBifs survived in intestinal tract in counts about 6 log CFU/g for 25 days. The control group without probiotic treatment consist of 6 animals. In both treat
