Abstract Title
COMPATIBILITY AND PRODUCTION PERFORMANCE IN COMMERCIAL LAYERS IMMUNIZED WITH rHVT-H7 AND rHVT-F VECTOR VACCINES APPLIED SIMULTANEOUSLY
Abstract
In Mexico, the main diseases affecting the poultry industry include Newcastle disease (ND) and Highly Pathogenic Avian Influenza (HPAI) subtype H7N3. Disease control and prevention were carried out using vaccines approved by the authority. Recently, animal health companies had developed different new technology vaccines, such as vector vaccines where a virus is used as a vector to carry the genetic information for the protective proteins of the inserted gene from another virus. Vector vaccines using the Marek herpesvirus of turkey (rHVT) vector have different advantages, among which are: there is no interference with maternal antibodies, applicable in the hatchery, and provides long duration of immunity.
There are already publications by different authors demonstrating the compatibility of two HVT-vector vaccines, namely, Vectormune® ND (rHVT-ND) and Vectormune® AI (rHVT-AI H5) are effective against Newcastle Disease and Avian Influenza respectively when given simultaneously. In Mexico, we have demonstrated the compatibility and advantages of using the combination of the two HVT-vector vaccines, namely Vectormune® ND (rHVT-ND) and Vectormune® H7 (rHVT-AI H7) in commercial layers under field conditions with the evidence of improvement in production parameters.
