Abstract

Live attenuated fowl cholera; fowl pox and pigeon pox vaccines were used to vaccinate turkey in a mutual manner. Six groups of turkeys (20 birds/group) were used. The first group was vaccinated with live attenuated fowl cholera and fowl pox vaccines via the wing web and feather follicle respectively. The second group was vaccinated with fowl cholera and pigeon pox vaccine, while the third group was vaccinated with fowl pox alone. The fourth group was vaccinated with pigeon pox vaccine alone and the fifth group was vaccinated with live attenuated fowl cholera vaccine alone. The sixth group was kept as unvaccinated control. The results of indirect haemagglutination test (THA) and ELISA revealed a significant increase in Pasteurella multocida antibody titers between group (1), group (2) and group (5). It could be concluded that the use of the pox vaccines enhance the immune response of turkeys to fowl cholera vaccine.
