Relationship between the vaccination of chicks with an infectious bursal disease vaccine and some live newcastle disease vaccines
Abstract: Primary laboratory experiments were carried out to reveal the immunogenic effect of a locally already produced Gumboro disease vaccine prepared from the imported attenuated (Bursa Vac M) strain, on chicks either previously vaccinated with some live Newcastle disease vaccines or not. These primary laboratory experiments indicated that the used Gumboro disease vaccine gave high protection percentage against Gumboro disease as shown out after challenge test, also it was shown that this vaccine has no immunosuppressive on the birds vaccinated by Newcastle disease live vaccine. This was indicated by the rise of the immunity level in the birds previously vaccinated against Newcastle disease. After obtaining these primary laboratory results ; 10.000 chicks in different private broiler farms were vaccinated with the mentioned Gumboro disease vaccine after being vaccinated with Newcastle disease vaccines according to the special vaccination programs of each farm. The results obtained from the laboratory experiments were identical with those obtained from the field ones. It was concluded that the locally prepared Gumboro disease vaccine (Bursa vac. M) Strain was safe and efficient in protecting the vaccinated birds against Gumboro disease ; also it was proved that this vaccine has no immunosuppressive effect on chicks previously vaccinated with live Newcastle disease vaccines.
