Effectiveness of the Pigeon Pox Vaccine on the Chicken Vaccinated With Avian Influenza Vaccine

Evaluation of the effectiveness of pigeon pox (PP) vaccine in improvement the required immunity to avian influenza (AI) virus vaccine in birds and reducing its shedding after challenge was the object of this study.Specific pathogen free chicks were vaccinated with PP and AI in 10 groups at 5 and/or...
