Comparative efficacy of different vaccination programs against Newcastle Disease
WVPAC Congress, 2019
The results of this trial show the importance of the live vaccines in the vaccination programme, not just because of the cellular immunity but also as a primer to the humoral response. The Hipraviar®S/H120 and the Hipraviar® Clon/H120 have a minimum titre of 10⁶∙⁵ EID50, the higher vaccine titres made a difference in the levels of antibodies.
The objective of this study was to determine the serological differences after 14 weeks of age in laying chickens using four different vaccination programs against Newcastle disease and a control non-vaccinated group against ND, using a commercial ELISA Kit (CIVTEST® AVI NDV).
