Data on the effects of the probiotic "Lacto Sacc"

The effects of the probiotic "Lacto Sacc" on the lactic acid concentration, pH value and microbiological status of the intestinal content and faeces, as well as the ileal digestibility of different nutrients and essential amino acids were studied in growing pigs into which a T-cannula had been inserted surgically at the proximal part of the duodenum and at the distal part of the ileum. No differences were found between the control and the experimental group in the measured parameters of the chyme samples taken from the duodenum. As a result of "Lacto Sacc" feeding, lactic acid concentration of the ileal content increased from 4.77% to 7.22% while its pH value decreased significantly (P < 0.05) from 7.39 to 6.42. The Streptococcus count was also significantly (P < 0.01) elevated. At the same time, the Escherichia coli count decreased significantly (P < 0.001) as a function of the elevated lactic acid concentration. The ileal digestibility of nutrients and essential amino acids improved by 1.3-16.1%. The favourable change observed in the microbiological status is attributed to the higher lactic acid concentration and the resulting lower pH, which adversely affect the survival of E. coli. Further studies are needed to reveal the factors responsible for the improved digestibility of nutrients.
