FOREWORD
A major objective of the Joint FAO/IAEA Division of Nuclear Techniques in Food
and Agriculture is to support research projects involving nuclear and related techniques
leading to improved animal production in developing countries. Chicken produced on a
relatively small scale, at the farmyard level, are an important source of animal protein for
human consumption in developing countries. Limiting factors to maximize this resource
include infectious diseases and overall production management. A Coordinated Research
Project on Small Scale Poultry Production was initiated in 1998 to evaluate the impact and
cost efficacy of inputs in management and veterinary care and provide guidelines to improve
the livelihood of farmers.
This publication contains the results of the FAO/IAEA Coordinated Research Project
entitled Assessment of the Effectiveness of Vaccination Strategies against Newcastle Disease
(ND) and Gumboro Disease (IBR) using Immunoassay-based Technologies for Increasing
Farmyard Poultry Production in Africa. Thirteen research contract holders in Africa evaluated
the major constraints to poultry production in different regions of their countries, analysed the
disease situation, management and marketing practises and developed improved
ND vaccination and husbandry strategies with the support of the four research agreement
holders. This exercise highlighted the added benefit strategic vaccination had on the survival
rate and the number of birds produced. A thermostable ND-vaccine seed strain (provided by
CSIRO, Australia) reduced the cost of vaccination substantially, as it could be produced
locally, with the added advantage of being thermo-resistant, thus reducing the need of a
prolonged cool chain. This was further improved by the training of “village vaccinators”
performing vaccine inoculations without the need of veterinary staff on place, insuring
vaccination frequency. The efficacy and the level of protection resulting from vaccination
were evaluated based on antibody titres. Management of chicks (overnight housing and creep
feeding) for the first six weeks improved production by a further 30%. The holistic approach,
i.e. vaccination together with management strategies, improved the survival of chicks by more
than 80%. It was also noted that women were playing an important role in the daily
management of backyard poultry. Furthermore, IBR and fowl pox infections had an adverse
impact on production in several locations, but never to the extent seen for ND. For these
situations, specific prophylactic vaccination programmes were developed. The use of the
isotope related technique ELISA for assessing disease status and vaccination protection was
key to the success of this CRP.
This TECDOC provides insight into the constraints faced by the informal farmyard
chicken production sector in Africa and describes strategies to overcome these limitations.
Lessons were learned and applied from a Bangladesh study that first identified, evaluated and
classified factors influencing poultry production before intervention. The results obtained
through this CRP are encouraging and will certainly help to increase poultry production in
general and improve the livelihoods of the rural poor. In the summary you will find the
condensed results obtained with methods explained in the expert presentations. The country
reports contain all background data.
The FAO and IAEA wish to express their sincere appreciation to the participants of
this CRP for their contribution to the CRP and the present publication. The IAEA officer
responsible for this publication is H. Unger of the Joint FAO/IAEA Division of Nuclear
Techniques in Food and Agriculture.

Abstract
In an FAO/IAEA Coordinated Research Project on backyard poultry production in Africa 13
laboratories all over this continent cooperated with seven research agreement holders to determine and
quantify specifically limiting production factors in this economic niche. Infectious diseases and in
particular Newcastle disease was major constraint. Lack of management practises added losses mainly
in young birds. The introduction of a new thermostable Newcastle vaccine produced easily in eggs and
applied by village vaccinators brought enormous economic advantages specifically where chicks were
managed for the first month after hatching and in most locations this could double the income
generated.
1. INTRODUCTION
The final Research Coordination Meeting (RCM) of the FAO/IAEA Coordinated
Research Project (CRP) "Assessment of the effectiveness of vaccination strategies against
Newcastle disease (ND) and Gumboro disease (IBR) using immunoassay-based technologies
for increasing farmyard poultry production in Africa" was held at the IAEA in Vienna,
Austria, 24–28 May 2004. The meeting ended a five-year programme and was attended by
research contract holders from Cameroon, Egypt, Ghana, Côte d'Ivoire, Kenya, Madagascar,
Mauritius, Morocco, Mozambique, Sudan and Tanzania and research agreement holders from
Bangladesh, Denmark, the Netherlands and Tanzania. Two counterparts were absent (Uganda,
Zimbabwe). The progress and results of this CRP were discussed, assessments of partial
budget analyses were performed and the various interventions such as ND and IBR-
vaccinations, anti-parasitic treatments and improved management practices, were ranked
according to their effectiveness. Participants all agreed that the CRP outcome would be
beneficial to the respective national poverty alleviation programmes.
2. BACKGROUND
Poultry research initiated by the Joint Division FAO/IAEA
Initial activities
An initial policy paper was produced by Barbara van der Eerden in 1996 that
suggested expanding the programme of the Animal Production & Health section to include
research activities on poultry. Two consultants, Anders Permin and Jonathan Bell, in close
collaboration with the staff of the Animal Production & Health Section, outlined the next year
a proposal for a research project on family poultry production in Africa. The research project
was designed with a holistic approach for the improvement of family poultry production in
1
Africa. External funding was sought from various donors, but proved difficult to obtain for
geographical reasons. Most donors at the time were concentrating their support efforts on a
single country or a relatively small region. By 1998 the Joint FAO/IAEA Division decided to
initiate the research on poultry using funds available through the Coordinated Research
Programme (CRP). The unique feature of a CRP is that with modest amounts of funds (US$
5000–8000 per contract holder) a number of scientists in different countries are able to initiate
applied research on the same subject using a similar approach in a coordinated fashion. The
results of a CRP will usually highlight the differences and similarities between production
systems of uniquely dissimilar environments and management approaches. Coordination is
facilitated by annual meetings (called Research Coordination Meetings or RCM’s) where
scientists can present and discuss the results of research. At the same time a number of
experts on the subject (called Research Agreement holders) are involved in the CRP to
provide assistance and advice during the entire length of the programme.

The Research Contract Holders received each year, over a five-year period, a
moderate amount of funds to enable them to initiate applied research on family poultry
production according to their work plans in their countries. The first two years were used to
gather baseline data on production characteristics of family poultry. The results have been
published in 2002 as an IAEA TECDOC (Characteristics and parameters of family poultry
production in Africa, ISBN 90–5782–094–3). The next three years of the CRP were devoted
to interventions in order to improve poultry production at the village level. The interventions
included vaccination of birds against Newcastle disease, Gumboro disease and fowl pox,
improvements in housing and feeding strategies and serological monitoring in order to select
the most suitable time for vaccination and assess the effectiveness and level of protection.
