Abstract
Cassava brown streak disease is a destructive disease that causes loss of cassava root in
terms of production volume and quality. The disease was reported in Tanzania for the
first time in 1936. The disease causes root rotting, the rotting is observed during
harvesting thus making the root not suitable for human consumption. The overall
objective of the study was to assess economic feasibility of using cassava affected by
cassava brown streak disease in poultry feeds. The specific objectives were to determine
farmers awareness on the presence and effects of the disease, to determine optimal feed
formulation with and without cassava inclusion, to compare the costs for feeds formulated
with affected and clean root and assess the profit generated by feeds formulated using
affected cassava. Data for this study were collected from Sengerema district and Mwanza
city. Three diets were formulated for broilers where two diets were cassava based and one
diet did not include cassava. The economic evaluation was based on the diets formulated
farmer’s awareness; linear programming (LP) model was used to identify optimal
profitability. The costs were compared between cassava based feeds and feeds without
statistically different at one percent level of significance (P< 0.01). Sensitivity analysis
was done to assess viability of using cassava in broiler diets. The study suggest that key
actors in cassava subsector and livestock sectors to create awareness of farmer and
processors on the possibility of using Cassava Brown Streak Disease affected cassava on
broiler feeds as new channel of cassava value addition.
