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.
