Effect of Parasite Control on Immune Response of Newcastle Disease Vaccination And Productivity of Free Range Chicken, Eastern Province, Kenya

Abstract: 
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.
Cette étude a été menée pour déterminer l’effet de réduire la charge parasitaire (par le traitement) sur l’efficacité de la vaccination contre la maladie de Newcastle (MN) chez le poulet fermier du village du district de Mbeere, en province orientale, au Kenya. Un seul aspect de l’étude a été achevé (p.ex. établir les niveaux du titre d’anticorps de MN dans le poulet à l’égard de l’humidité de l’âge de la saison). Il y avait un effet significatif de la saison (P = 0,05) sur le titre de l’anticorps de MN, avec plus dans la saison des pluies. Par conséquent, l’effet de la saisonnalité sur l’occurrence de la maladie implique que les approches de gestion pour la MN devraient être conçues pour fournir des soins au maximum pour les oiseaux pendant la saison humide. L’effet de l’endoparasite et l’ectoparasite sur l’efficacité du vaccin contre la MN est toujours en cours.

The 2012 RUFORUM Biennial Conference is the third in the series. The main objective of the Biennial conferences is to provide a platform for agricultural research for development stakeholders in Africa and beyond to actively exchange findings and experiences, while at the same time learning lessons towards improving performance of the agricultural sector and ultimately people’s livelihoods. The biennial conference is RUFORUM’s most comprehensive meeting for the diversity of stakeholers in agriculture. It is especially dedicated to graduate students and their supervisors, grantees in RUFORUM member universities and alumni. It is a platform for peer review, quality control, mentorship, networking and shared learning. The third Biennial Conference was attended by 657 participants.This record contains an extended abstract accepted under the theme of Animal Health Management
