Gastrointestinal tract colonization evaluation in pigs by Lactobacillus acidophilus and Streptococcus thermophile strains, components of a probiotic product. Rev Salud Anim.

With the aim of evaluating the possible use as a probiotic product composed by Lactobacillus acidophilus and Streptococcus thermophilus, the intestinal tract colonization of newborn pigs was studied by the components of this product. As a probiotic, a mixture of 150 ml of molasses and 100 mg torula yeast was used and water was added completing 1000 ml and 25 ml of Lactobacillus acidophilus and Streptococcus thermophilus culture was added. Four experimental groups were formed as follows: Group 1: 18 piglets (a litter of two sows) which was applied 5 ml of the probiotic product orally at birth; Group 2: 17 piglets (a litter of two sows) which were applied 5 ml of the probiotic product orally at birth and at 24 hours after the first treatment; Group 3: 10 piglets (a litter of one sow) which were applied 5 ml of placebo orally at birth and Group 4: 12 piglets (a litter of one sow) which were applied 5 ml of placebo orally at birth and at 24 hours after the first treatment. A microbiological sampling by rectal swabs at 7, 14 and 21 days postreatment was applied to all animals. The gastrointestinal tract colonization by Streptococcus thermophilus and Lactobacillus acidophilus was observed in pigs treated with the probiotic product until 14 days postreatment not being and this is not influenced by the frequency of probiotic application.
