The polysaccharide-containing extracellular fractions (EFs) of the edible mushroom Pleurotus ostreatus have immunomodulating effects. Being aware these therapeutic effects extracts, we investigated synergistic relations between extracts and BIAVAC BIAROMVAC vaccines. These vaccines target stimulation immune system in commercial poultry, which are extremely vulnerable first days their lives. By administrating EF with polysaccharides from P. to unvaccinated broilers noticed slow maternal antibodies against infectious bursal disease (IBD) starting four weeks post hatching. For vaccinated a low almost complete lack IBD has been recorded. adding 5% 15% water intake, as compared reaction previous experiment, level was increased. This led us believe that by using this combination vaccine can obtain good results stimulating production period chicken life, critical broilers’ survival. be rationalized newly proposed reactivity biological activity (ReBiAc) principles examining parabolic relationship administration recorded activity.
