Publication Nutrients, Functional Properties, Storage Stability and Costing of Complementary Foods Enriched with Either Termites and Fish or Commercial Micronutrients(Wageningen Academic Publishers, 2015) Kinyuru J.N.; Konyole S.O.; Omolo S.A. Onyango; Kenji G.M.; Onyango C.A.; Owino V.O.; Owuor B.O.; Estambale B.B.; Roos N.Application of edible insects in complementary food production has not been studied much. This study developed and evaluated complementary foods based on edible termites to combat child malnutrition in Kenya. Two complementary foods, Winfood Classic (W-C; containing termites and dagaa fish) and Winfood Lite (W-L; without termites and dagaa fish) were formulated and processed by extrusion cooking. Their nutrient content, functional properties, storage stability and cost of the foods were evaluated using standard methods. W-C contained significantly higher (P=0.37). The energy contribution from fats (26.1 E%) from W-C was within the recommend levels in complementary foods while energy from proteins (protein E%) was higher from the two foods (18.0 and 14.3 E%, respectively). Bulk density was significantly different (P=0.02) amongst W-C and W-L and within the recommended levels of ≤0.5 g/cm3 in complementary foods. The foods were shelf stable for 6 months of storage with neither pathogenic microorganisms nor aflatoxins reported. Peroxide value was below the limits (≤10 meq/kg) after 6 months of storage. Production cost of the foods was 3.21 and 2.23 US$/kg for W-C and W-L, respectively, with termites contributing 42.3% of the basic cost of production in W-C. The study confirms that termites and dagaa fish can be utilised in processing of affordable and safe complementary foods with adequate nutrient density.Publication Relationship between Level of Participation of Researchers, Extension Agents and Farmers in On-Farm Research Trials and Adoption of Technologies Case Study: Maize and Beans Producers, Kenya(Institute of Development Studies, 2014) Ochola W.A.; Basweti E.A.; Ogendi G.M.; Onyango C.A.; Ochola W.O.This study was conducted to determine the relationship between level of participation of researchers, extension agents and farmers in on-farm research trial activities and level of adoption of technologies developed through that process. The study was based on technologies used to improve the productivity of maize and beans in southwest Kenya. The study used an ex-post facto research design with a survey methodology. It was designed to use three sets of questionnaires directly administered to farmers, extension agents and researchers to collect data from the researchers, farmers and government extension agents. Stratified random sampling technique was used to select 104 respondents. The study established that; there was a significant relationship between occupation of respondents and their level of participation; there was a significant difference between the level of involvement of farmers, extension agents and researchers with the mean participation of the extension agents being relatively high compared to the researchers and farmers in on-farm related activities. However, there was low level of interaction between the researchers, extension agents and farmers; and there was a significant relationship between agro-ecological zones (AEZs) and level of participation of farmers with farmers at higher AEZs having higher participation levels compared to the farmers at the lower zones. The study finally concluded that, there was a strong positive relationship between the level of participation and level of adoption. The study therefore recommends that extension agents and researchers should consider improving their level of participation in joint activities.
