Abstract: This study planned to vaccinate ostriches with mixed living attenuated fowl pox and inactivated Newcastle disease vaccines. Fourteen ostriches were used and divided into four groups. The 1st group was vaccinated with fowl pox vaccine, the 2nd group was vaccinated with Newcastle disease vaccines, the third group was mixed with fowl pox and Newcastle disease vaccines at the time of vaccination, and the fourth group was kept as non vaccinated controls. Blood and serum samples were collected from all groups after vaccination and challenged for testing the cell mediated immune response by using the lymphocyte transformation test, and the humoral immune response by using serum neutralization test. The results revealed that the lymphocytes activity rate and neutralizing antibodies titres obtained by group III was better than group I and II. Confirmation of these results was applied by challenging group I,III and IV with virulent fowl poxvirus and groups II,III and IV with virulent Newcastle disease virus. It proved that the variations in the lymphocytes activity rate and neutralizing antibodies titres during the experiment did not affect the protection levels of ostriches when exposed to challenges with the specific virulent virus. This provokes the use of mixed vaccination to save time, labour and effort during vaccination.
