    Conceptualizing the Student-Centered Outreach Model for experiential learning and community transformation
    (African Journal of Rural Development, 2016-12) Kalule, S.W.; Odongo, W.; Kule, E.; Ndyomugyenyi, E.K.; Omara, P.; Ongeng, D.
    A dominant discourse in higher education has widely called for reviewing, redesigning and alignment of the curricula to suit the current and future skills demands in the labour market. In response, universities have over time been repositioning themselves to develop practical approaches to produce graduates with skills relevant to the job market. One such approach is the Student-Centered Outreach (S-C-O) model conceived and run at Gulu University in Uganda. However, little is known about the S-C-O model and thus this paper sought to develop and present a conceptual framework that underpins the functioning of the model. The structural set-up of the framework shows that students are centrally positioned between the faculty and the community. A key resource connecting the actors in the S-C-O model is knowledge which is gained through learning that takes place from either the top or bottom side of the S-C-O model and integrating feedback to close the learning loop. Examination of the implementation of the S-C-O model reveals that the model realizes three important outcomes: (i) enhancing experiential learning, (ii) promoting university linkage with the community, and (iii) enhancing transformation of the farming practices. The need for further studies as part of a process to develop an empirical methodology for examining the impacts of this outreach model remains apparent.

    Dynamics of Cyanogens and In-Vitro Degradability of Cassava Peels as an Indicator of its Nutritional Value as Animal Feed
    (Livestock Research for Rural Development, 2015-06-03) Taabu, H.L.; Ndyomugyenyi, E.K.; Mutetikka, D.; Wasswa, D.
    The in-vitro degradability of cassava peels and its relationship with the cyanogenic potential of five cassava varieties grown in Uganda was investigated to study the potential of cassava peels as an energy source in animal feeds. The cassava varieties included NASE 3, NASE 4, NASE 10, TME 14 and Tongolo. The first four varieties were considered to be of low to medium cyanogenic potential (CNp), while the last one contained high CNp. Cassava peels had 25.5 ± 6.6% dry matter (DM), 86.6 ± 0.9% organic matter (OM) and 56.8 ± 5.8% neutral detergent fibre (NDF). Degradability of DM, OM and NDF was 74.8± 4.2%, 74% ± 7.5% and 44.2 ± 7.5% respectively. Total cyanogenic potential and free hydrogen cyanide (HCN) in the fresh peels ranged from 923 to 2815 and 33 to 676 mg HCN equivalent kg-1 DM respectively. These levels dropped by 27- 88% and over 90% respectively, when the peels were dried. For all varieties, the residual cyanogenic potential after drying the peels fell within the safety limits recommended by FAO/WHO for food and feed. The study showed that using fresh peels in sufficient amounts for feeding animals, particularly monogastrics, is potentially harmful due to high cyanogenic potential. Drying the peels can, however, reduce the cyanide toxicity risks. The low NDF degradability reduces the nutritional value of cassava peels if they are used as a sole source of energy in ruminant diets.

    EFFECT OF INDIGENOUS MICRO-ORGANISM TREATMENT OF DEEP LITTER FLOOR ON NUTRIENT CONTENT OF PORK
    (African Crop Science Journal, 2020-10-02) Kidega, K.; Ndyomugyenyi, E.K.; Okello-Uma, I.
    Pork meat consumption and its products are constrained by high fat content, particularly high composition of saturated fatty acids. The objective of this study was to investigate the effect of indigenous micro-organism (IMO) treatment of deep litter floor, on nutrient content in pork of pigs raised on IMO treated and untreated deep litter floor. Twenty four three-months old pigs (Large White x Landrace) were raised on deep litter floor; one floor type treated with IMO solution and the control not treated. Significant (P<0.05) differences were observed in the amount of saturated, mono-unsaturated, poly-unsaturated, cis, trans and omega-6, 7 and 9 fatty acids in pork of pigs raised on IMO treated and untreated deep litter floor; with more unsaturated fatty acids in pork of pigs raised on deep litter floor without IMO treatment (63%) than pigs kept on deep litter floor with IMO (37%). Therefore, deep litter floor treatment with IMO solution does not affect nutrient contents in pork, but enhances the composition of unsaturated fatty acids. Further research should be conducted on the mechanisms by which deep litter floor whether treated or untreated with IMO solution modifies fatty acids composition in pork.
