Control of Newcastle disease in village chickens

Between 1983 and 1992, ACIAR invested A$3 million in research to find a vaccine that could provide protection from Newcastle disease in chickens and be applied in village environments in developing countries. A further
$160 000 was invested in follow up projects which ended in 1996. The results of this analysis indicate that on the basis of conservative assumptions, the benefits from the research have already outweighed the costs. In the longer term, the discounted net present value of the research is estimated at $211 million. Malaysia and Vietnam have been the major beneficiaries to date, but large benefits are also expected in Africa.
