Abstract

This paper assesses the impact of chicken vaccination on farmers’ income. A dynamic simulation model, VIPOSIM, combined with benefit-cost techniques, was used ensuring that both, the dynamic aspects of village poultry production system and selection bias are addressed. The findings of this study reveal that, in general, Newcastle Disease (ND) control results in a considerable increase in farmers’ income. Economic profitability is not the underlying factor for low rates of chicken vaccination. To address adequately the adoption of ND control technology, the government should concentrate efforts on the strategies of extension and distribution of the vaccine.
