Abstract

114 words

This study was conducted to determine the effect of reducing parasite burden (through treatment) on effectiveness of Newcastle disease (ND) vaccination in free-range village chicken of Mbeere district, Eastern province, Kenya. Only one aspect of the study has been completed (i.e., establishing ND antibody titre levels in chicken with respect to age wetness of season) There was a significant (P=0.05) season effect on ND antibody titre, with more in the wet season. Therefore, seasonality effect on occurrence of disease implies that management approaches for ND should be designed to provide maximum care for birds during the wet season. The effect of endo- and ecto-parasites on the effectiveness of the ND vaccine is still on-going.
