Oil with a high content of omega-3 polyunsaturated fatty acids (PUFA) was administered for 4 weeks to experimental (E) germ-free piglets. Control (C) piglets were administered saline solution in identical doses. Both groups of piglets were inoculated perorally with Lactobacillus casei subsp. casei from 21 days of age. At the age of 28 days, the number of Lactobacillus casei subsp. casei that had adhered to jejunal mucosa of E piglets was significantly higher than in C animals. The differences in the number of lactobacilli which colonised mucosa of the ileum and colon were insignificant. With the exception of the stomach, the pH level in the digestive tract was lower in E than in C piglets. Significantly higher levels of propionic, acetoacetic and succinic acids were observed in the colon of E animals. The differences in the level of lactic and acetic acid were insignificant. PUFA-potentiated probiotics positively affected the adhesion of lactobacilli, pH and the level of organic acids in the digestive tract of germ-free piglets. Supplementation of oil containing omega-3 PUFA significantly increased the blood level of alpha-linolenic, eicosapentaenoic and docosahexaenoic acids in E piglets at the expense of arachidonic acid.
