title: [The nutritive efficiency of Bacillus cereus as a probiotic in the raising of piglets. 1. Effect on the growth parameters and gastrointestinal environment].
abstract: In an experiment with 4 x 12 piglets the probiotic effect of the Bacillus cereus strain FH 1457 S on the performance and changes in the gastrointestinal tract was studied. Beside a negative control the feed was supplemented with 10(7), 10(8) and 10(9) CFU Bacillus cereus/kg. The experiment included two feeding periods, whereby in the first a prestarter and in the second a piglet rearing feed was administrated ad libitum with the animals kept individually in cages. Over the whole feeding trial the piglets with the additions of 10(7), 10(8) und 10(9) CFU Bacillus cereus/kg feed showed higher daily weight gains of 9.5%, 11.1% and 8.6% with an increased feed consumption of 11.1%, 11.0% and 7.9%. The feed conversion rate was not influenced by the additions. In the first period daily weight gains were increased by 8.9%, 14.7% and 7.8%, the feed consumption in this period was 10.2%, 12.1% and 7.2% higher than in the control group. The addition of 10(8) CFU Bacillus cereus had a significantly higher daily weight gain in the first period compared to the control and the feed conversion rate was improved by 2.4%. In the second period the daily weight gains were increased by 9.9%, 8.9% and 9.1%, the feed consumption by 11.4%, 10.5% and 8.8% because of Bacillus cereus addition to the feed. The frequency of diarrhea was not influenced by the treatments. In each Bacillus cereus dosage the concentrations of ammonia, lactate and volatile fatty acids in small intestine contents were mostly diminished. In caecum contents the concentrations of acetic and propionic acid were decreased in the groups supplemented with Bacillus cereus.
