Summary of the Thesis

Local chicken farming is potential for poverty reduction and enhancing food security. The study adopted developmental design whereby farmers were earlier on provided with vaccinated 20 six week old Sasso and Kuroiler chicken strains. The study applied a Farm Simulation Model, Stochastic Efficiency with Respect to Function, Adoption and Diffusion Outcome Prediction Tool, Stochastic Data Envelopment Analysis and the Just and Pope Framework in assessing economic potential of these chicken strains.

The results indicate that keeping the newly introduced chicken strains is a more economically viable business with the highest NPV, Income and probability of attaining economic return.

Extremely risk-averse farmers preferred local chickens and would need to receive about US$170 and US$130 for keeping about 60 Sasso strain and 60 Kuroiler strain respectively, to be indifferent. If the introduced chicken strains are made available, the peak for adoption is likely to be 33% after 8 year; and reduced start-up costs, extension services and inputs are facilitating factors. On the other hand controllable input factors influence performance variability, exposing farmers to risk.

The study recommends promotion and scaling up of these strains for improving the livelihood of farmers and increasing the sector’s contribution to GDP. In addition, integration of good farming practices, feed formulations, strengthen market for both inputs and outputs are crucial for improved productivity, efficiency, performance stability and hence profit maximization.
