Using feed acidifiers, garlic and microbial cell extracts, a liquid product was developed and applied in a concentration of 1 ml/litre in drinking water before and during immunisation of poultry. The application of the experimental product started 2-3 days before vaccination and continued for 17-20 days. Consequently, there was a 37.6 to 266% increase (on the basis of geometric mean titre values) in antibody production of the treated vs. control groups in several poultry models. These included parenteral application of vaccines prepared from inactivated goose parvovirus, Newcastle disease and Gumboro disease viruses, and from live egg drop syndrome (EDS) virus as well as from killed Salmonella enteritidis, Pasteurella multocida and Leptospira pomona bacteria.
