AN ATTEMPT TO EVALUATE THE USEFULNESS OF LEVAMISOL IMMUNOMOULATIVE PROPERTIES IN VARIOUS PROPHYLACTIC SYSTEMS (SCHEMES) AND IN THE CONDITIONS OF A LARGE PIG HERD

摘要

The research concerning the therapeutic and prophylactic properties of levamisol, connected with its immunomodulative effects, was conducted. A distinct improvement in the health state of animals was observed. It manifested itself in a reduced mortality level and increased daily body weight gains. The lack of intensified immune response at repeated antigen exposure was also confirmed. It indicates the need for further studies aimed at explaining those intere-sting phenomena.
