The aim of the study was to determine the effects of feed addition of LAVIPAN PL5 probiotic preparation containing compositions of microencapsulated lactic acid bacteria (Leuconostoc mesenteroides, Lactobacillus casei, Lactobacillus plantarum, Pediococcus pentosaceus) on production parameters and post-vaccinal immune response in pigs under field condition. The study was performed on 400 pigs in total and 60 pigs from this group were used to evaluate the effect of the product tested on the post-vaccinal response. The animals were divided into two groups: control group, fed without additive of LAVIPAN PL5 and the study group, receiving LAVIPAN PL5 at doses recommended by manufacturer from weaning to the end of fattening. The following parameters were recorded: main production parameters, including weight gains, fattening time (slaughter age) and animal health status during the study (mortality), and specific humoral post-vaccinal response after vaccination against swine erysipelas. The results indicate that the application of LAVIPAN PL5 had positive influence on the animals` productivity and did not significantly affect the post-vaccinal antibody levels and the development and maintenance of the post-vaccinal response, albeit the levels of antibodies were slightly higher in the animal receiving the test preparation. The higher average daily weight gains (by over 3%) which resulted in a 2 kg higher average weight at slaughter and a reduction of the fattening period by 5 days, undoubtedly contributed to significant economic benefits.
