Reducing Animal Feed Costs by Black Soldier Fly Larvae (BSFL) from a Food Waste Management System under the Khok Nong Na Model in Nakhon Phanom Province

Abstract

The objective of this research was to study the reduction of animal feed costs by black soldier fly derived from a food waste management system under the Khok Nong Na Model in Nakhon Phanom province, in support of sustainable development in Nakhon Phanom Province. The research activities were divided into three phases. Phase 1 focused on establishing production stability of black soldier fly through training programs and the design of a rearing system utilizing organic waste from local communities as feed materials. Phase 2 aimed to develop processes for economic sustainability by improving production procedures based on SWOT analysis results to enhance system efficiency and long-term sustainability. Phase 3 emphasized knowledge transfer and the development of community trainers, disseminating expertise on black soldier fly rearing to neighboring communities and preparing local trainers to expand the initiative through learning centers. The research results showed that after implementation in the target areas, Kutakai, Na Hua Bo, and Na Khu sub-districts, farmers were able to significantly reduce animal feed costs. Expenditures on externally purchased animal feed decreased by 50–100%. Specifically, farmers in Kutakai sub-district reduced feed costs by 50%, those in Na Hua Bo sub-district achieved a 100% reduction, and farmers in Na khu sub-district reduced feed costs by 50%. In addition, the establishment of a food waste management system and the development of community trainers for black soldier fly rearing demonstrated potential for further development as a community-based learning
innovation. Recommendations from this research include expanding the implementation to other areas to increase positive impacts and further improving food waste management processes to enhance efficiency.
