Item Farmer demand and willingness-to-pay for sweetpotato silage-based diet as pig feed in Uganda(Journal Article, 2020-08-11) Asindu, Marsy; Ouma, Emily A.; Elepu, Gabriel; Naziri, D.Smallholder livestock farmers across Sub-Saharan Africa are racing against time to find cheaper, nutritious, and sustainable feed alternatives to the more pronounced and expensive commercial concentrates amidst the increasing global demand for livestock products. Lately, many prominent feed conservation technologies have been developed, with a notable example being the sweetpotato silage technology that turns wasted sweetpotato components into a palatable and nutritious livestock feed. However, despite the potential benefits associated with these technologies, the level of demand and acceptance among smallholder farmers remains largely unknown. Thus, this paper assesses the farmer demand and willingness-to-pay (WTP) for sweetpotato silage-based diet as pig feed by smallholder farmers in Uganda. The information for the study was collected through secondary data review and semi-structured interviews to assess farmer WTP. The 256 semi-structured interviews were randomly drawn from 16 purposive clusters formed at a radius of 3 km around 16 farmers piloting sweetpotato silage-based diets for pig feed. The results show that pig farming is mainly the responsibility of women, with farmers’ mean willingness-to-pay price amounting to 0.20 USD per kilogram of sweetpotato silage-based diet. At the mean price, the annual demand for silage was estimated at 17,679 tons, with a market potential of approximately 3.59 million USD. The study concludes that, at the mean willingness-to-pay price, there is a substantial market potential that can be exploited by small and medium-sized enterprises (SMEs) venturing in the livestock feed industry.Item Post-harvest physiological deterioration effects and gender dynamics in the retail marketing of fress cassava roots.

PHL reduction strategies offer unique opportunities to contribute to sustainable food systems for increased food security and farm incomes for more than 200 million food insecure people in sub-Saharan Africa. Lack of empirical information remains a major challenge to operationalization of PHL reduction strategies in many countries of the region. This paper utilizes cross-sectional data to determine the extent and factors that are influencing postharvest losses in the cooking-banana value chain in Uganda. We find that 14.9% of all the cooking bananas that are produced in Uganda suffer postharvest deterioration along the value chain (7.2% of the bananas deteriorate completely and have no residual value, while 7.7% deteriorate partially and are sold at discounted prices), mostly affecting retailers. At farm level, female headed households experience more losses than those headed by males. Household headship, household size, proportion of land allocated to banana production, and monthly banana production are the principal determinants of PHL at farm level. At retail level, such losses are mainly determined by sex of the vendor and group membership. The findings call for comprehensive and gender-responsive PHL reduction strategies.Item Postharvest losses along the cooking banana, potato and cassava fresh value chains in Uganda.(Presentation, 2017-03) Kikulwe, Enoch MutebiItem Technical report: Effect of sweetpotato silage diets on performance of growing pigs in Uganda.(Report, 2017-02) Ojakol, J.F.; Lule, Peter M.; Kyalo, Gerald; Pezo, Danilo A.; Naziri, D.; Lukuyu, Ben A.; Mutetikka, D.Item Technical report: An evaluation of current pig feeding practices on smallholder farms in Masaka and Kamuli districts of Uganda.(Report, 2017-01) Lule, Peter M.; Lukuyu, Ben A.Item Technical report: Improved potato harvesting techniques.(Report, 2017-03) Wasukira, A.; Sasa, R.; KIptala, M.; Banan, J.; Chemusto, D.; Walimbwa, K.; Gidoi, R.; Owere, L.Item Store management plan.(Manual, 2016-07) Mengya Integrated Farmers AssociationItem Reducing post-harvest losses and promoting product differentiation in the cooking banana value chain.

Information was collected through key informant interviews, secondary data review, sweet potato root peeling and weighing, focus group discussions with pig and sweet potato producers covering a sample of 180 farmers. Semi-structured interviews with 240 respondents (120 sweet potato farmers, 60 pig farmers and 60 sweet potato traders) were also conducted. The results showed that sweet potato production is seasonal with substantial wastage of sweet potato components existing across the various nodes of the sweet potato value chain. The study concludes that there is an opportunity for investment in sweet potato silage business that has the potential to reduce wastage of sweet potato and bridge the feed scarcity gap faced by pig farmers.Item Technical Report: Market and value chain analysis of ware potato from eastern Uganda with a focus on postharvest management practices and losses(Report, 2017-09) Tatwangire, A.; Nabukeera, C.Item Workshop Report: Farmer training on sweetpotato silage making in Kamuli district.(Report, 2015-10) Kabirizi, J.M.; Kyalo, Gerald; Kizito, J.; Kigongo, J.Item Workshop report: Farmer training on sweetpotato silage making in Masaka district.(Report, 2015-10) Kabirizi, J.M.; Lule, Peter M.; Mayuba, J.; Kigongo, J.Item Workshop Report: Training of trainers on sweetpotato silage making.(Report, 2015-09) Kabirizi, J.M.Item Sweetpotato silage: a nutritious and affordable feed solution for small-scale pig farmers.(Brochure, 2017-10) CGIAR Research Program on Roots, Tubers and BananasItem Making high quality sweetpotato silage: An improved tube silage making method - Luganda.(Training Material, 2015-09) Lukuyu, Ben A.; Gachuiri, C.K.; Agili, S.; León Velarde, C.U.; Kirui, JosephineItem Sweetpotato silage making manual(Training Material, 2015-09) Kabirizi, J.M.; Lukuyu, Ben A.; Mayanja, S.; Lule, Peter M.; Kyalo, Gerald; Naziri, D.
