| dc.description.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. | |
