<br/><br/> Bee glue (propolis) was collected from local bee cells at summer season, 1996 in Sharkia Governorate to study the Physical properties, immunological effects and clinical evaluation of ethanolic extract of propolis (EEP) for vaccination against Newcastle disease in Broiler chickens. Egyptian propolis possesses considerable antiviral and immunological activities against Newcastle disease (ND) infection in chickens especially when administered with ND vaccines at the periods of first day through its effect on cell mediated (mainly) and humoral immunities. The potential of propolis in the prevention or treatment of Newcastle disease infection is worth, further extensive evaluation to confirm these effects, formulate recommendations for the practitioners and practical applications of such natural product as its possible anti Newcastle disease immunostimulent in poultry field required more study.
