    Black soldier flies as a latent driver to attaining selected SDGs in a developing country context- the case of Uganda
    (Sustainable Environment, 2025-03-17) Kasima, Junior Senyonga; Mugonola,Basil; Menya, Emmanuel; Ndaula, Sulaiman; Ndyomugyenyi, Elly Kurobuza
    In developing countries, minimal progress has been made towards the attainment of Sustainable Development Goals (SDGs). This is because of low investment in innovations towards this endeavor. In this paper, 143 peer-reviewed journal articles and non-journal sources were reviewed to explore the potential of Black Soldier Fly (BSF) rearing as a cost-effective innovation for achieving SDGs 1, 2, 3, 7, and 13. Uganda was chosen for its median position among developing countries, making its practices adaptable to countries on either side of the scale. BSF can contribute to the attainment of the five SDGs through its products and/or services, including environment-friendly waste management, larvae for animal feeds, frass for organic fertilizer, and chitin for pharmaceutical use. This review discusses the significant potential of integrating BSF into strategies to achieve the selected SDGs in a developing country. However, the limited data on organic waste generation could not permit precise statistical estimates of BSF’s potential contribution to each SDG. Future studies, supported by reliable data, should precisely assess the feasibility of BSF rearing as a cost-effective innovation for attaining the SDGs. Future research should also explore the influence of policy and consumer behavior on the adoption and utilization of BSF-based products.

    Current Status and Potential Opportunities for Uganda’s Pig Sub Sector: A Review
    (Science and Development, 2024-12-20) Kasima, Junior Senyonga; Mugonola, Basil; Muyinza, Harriet; Ndyomugyenyi, Elly Kurobuza
    Pig production is one of the most important livestock sub-sectors in agricultural economy of Uganda. However, pig production is not a priority enterprise in the government endeavors to uplift livelihoods of Ugandans, which has deterred the sub-sector from realizing its full potential. This review explores opportunities that pig farmers and policy makers could exploit to improve pig production in the country. Since gender inclusivity is pivotal in global agricultural development, the review examines the level of gender inclusivity in Uganda’s pig production, the key constraints to pig production, and opportunities that could boost growth of the sub-sector. The review has identified that there is an increase in female participation in pig production, which portrays realization of faster growth of Uganda’s pig production. This faster growth might however be deterred by frequent African Swine Fever (ASF) outbreaks, high cost of feeding and low quality of feed materials due to aflatoxin contamination. Offensive smell from pig houses could also constrain pig production especially in densely populated areas. Potential opportunities for Uganda’s pig production include use of alternative feeds like black soldier fly larvae and biochar. Black soldier fly larvae grow on readily available organic wastes and are rich in proteins while biochar improves the immunity of pigs. Nixtamalization, a process involving the treatment of maize with an alkaline solution to reduce aflatoxin levels, could be explored to mitigate feed contamination while indigenous microorganism solution could be applied on deep litter beddings to reduce offensive odor in pig house. In conclusion, the study observed that Uganda has untapped opportunities that, once utilized, could improve pig production. These, if adopted, could contribute to a swifter take-off in the pig sub-sector and ensure that future domestic demand for pork is met by our own production. The potential alternatives are also applicable to pig production in any developing country.

    Indigenous Microorganisms as an alternative Odour-reduction approach in Pig Production systems: A review
    (Science and Development, 2025-07) Ndyomugyenyi, Elly Kurobuza; Kasima, Junior Senyonga
    Odour emissions from pig production facilities are the most significant limitations to pig production. Effective interventions to control odour such as dietary modification, liquid-solid separation, bio-filtration, covers for manure storage, and dust suppression have been made. However, these measures are costly and unaffordable by most pig farmers. The use of Indigenous micro-organisms (IMOs) has been suggested as a less costly alternative approach to control odour. The IMOs can be used to manage odour in a natural and environmentally beneficial way. They aid in the breakdown of organic materials and lessen the offensive smell by introducing helpful bacteria to the farm. The micro-organisms help to break down faecal material rapidly to a fertilizer rich material, while ensuring that there are no smells or flies. This enables rearing of pigs close to the living quarters in areas where land is scarce and heavily populated, hence encouraging more farmers to adopt the enterprise. This review focuses on the use of IMOs as a less costly approach to control odour in pig production systems.

    Performance of local and local x improved chicken crosses under semi-intensive management system in Northern Uganda
    (Cogent Food & Agriculture, 2023-05-19) Ochora, Samuel; Kasima, Junior Senyonga; Okot, Wilfred Marion; Ndyomugyenyi, Elly Kurobuza
    Despite the efforts to improve Uganda’s chicken production through crossbreeding, limited research has been conducted to establish the performance of local x improved chicken crosses under the dominant management systems used by chicken rearing households. The current study aimed to assess the performance of local x improved chicken crosses under semi-intensive management system in Pader and Agago districts of Northern Uganda, where crossing of local with imported Kuroiler chickens has been promoted over time. A cross-sectional survey using a semi-structured pre-tested questionnaire and observation was conducted in two purposively selected sub-counties per district among 246 respondents to establish the sociodemographic characteristics of chicken farmers and reasons for crossing. Using a Completely Randomised Block Design, an experiment was set up to compare the performance of local chickens and local x improved chicken (Kuroiler) crosses in terms of egg production and hatchability. All respondents practiced crossing with the aim of enhancing egg production in their chicken flocks. Under semi-intensive management system, hatchability of the eggs from crossbred chickens did not differ (P ≥ 0.05) from that of the eggs laid by the local chickens. In conclusion, although crossbred chickens exhibited hybrid vigour in terms of egg production under free range and semi-intensive systems, the hatchability of the eggs from crossbred chickens raised under semi-intensive system did not differ from that of eggs from local chickens. Future research should consider establishing the quality attributes of eggs of the local x improved chicken crosses in the dominant management systems among chicken keeping households in Uganda.
