Conceptualizing the Student-Centered Outreach Model for Experiential Learning and Community Transformation
(African Journal of Rural Development, 2016) 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) 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 Feeding Sweet Potato Vine-Based Diets as Partial Milk Substitutes for Dairy Calves in Uganda
(Livestock Research for Rural Development, 2016) Taabu, H.L.; Ndyomugyenyi, E.K.; Mutetikka, D.; Ebong, C.
A study was conducted to determine the potential of sweet potato vine-based diets as partial milk substitute (PMS) for dairy calves. Twenty five Friesian bull-calves weighing 38.7 ± 4.56 kg were fed composite meals containing 0, 30, 40, 50 and 60% air-dried sweet potato vines (SPV) as partial milk substitutes in a completely randomized design (CRD) over a seventy day period. Dietary treatments were introduced 15 days after calving. Milk offered was reduced by one litre every fortnight until 70 days after birth. Proximate and mineral analyses were carried out for ingredients and dietary treatments. Feed intake (FI), average daily weight gains (ADG), feed: gain ratio and variable cost per unit of gain were computed over the experimental period.
Effect of Indigenous Micro-Organism Treatment of Deep Litter Floor on Nutrient Content of Pork
(African Crop Science Journal, 2020) Kidega, K.; Ndyomugyenyi, E.K.; Okello, Uma
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.
Evaluation of the Nutritional Value of Boiled Java Plum Beans in Broiler Chick Diets
(Livestock Research for Rural Development, 2008) Ndyomugyenyi, E.K.; Kyarisiima, C.C.; Bareeba, F.B.; Okot, M.W.
In Uganda, the price of maize as the main source of energy in poultry feed is prohibitive due to its scarcity and competitiveness. Therefore, research is required to study the nutritional value of alternative energy feedstuffs such as Java plum (Syzygium cumini) beans (JPB). Chemical analysis and one feeding trial were conducted to assess the nutritional value of boiled Java plum beans (BJPB) in broiler chick diets. In the feeding trial, boiled Java plum bean meal (BJPBM) substituted maize meal (MM) by 0, 25, 50, 75 and 100% in broiler starter diets. The BJPB had dry matter (DM) content of 85.0±2.03%, nitrogen free extract (NFE) of 72.9±1.95%, calculated metabolisable energy (ME) of 13.3±0.25MJ/kg, crude protein (CP) of 4.23±0.48%, ether extract (EE) of 1.05±0.17%, crude fibre (CF) of 5.06±0.72%, ash of 1.75±0.11%, phosphorus (P) of 0.11±0.02% and calcium (Ca) of 0.05±0.01%. In the feeding trial, diets with BJPBM significantly (P < 0.05) depressed chick growth. Feed intake was significantly (P < 0.05) reduced above 25% replacement rate whereas feed efficiency did not change much. There was no mortality in the control treatment and at 25% boiled Java plum bean-maize replacement rate. The study showed that BJPBM cannot replace MM in broiler starter diets without deleterious effects on the birds. The boiling treatment did not improve the nutritional value of JPB.
Feed Utilizable Resources Availability and Utilization in Urban and Peri-Urban Areas of Kampala and Mbarara Districts, Uganda
(Livestock Research for Rural Development, 2015) Taabu, H.L.; Ndyomugyenyi, E.K.
A study was conducted in Kampala and Mbarara districts, Uganda to identify and document locally available feed resources for commercial beef production. A total of 72 respondents from each district were used for the study. Data were collected using structured questionnaires, observations, and interviews. Secondary sources of data were also reviewed. Over 60% respondents used zero-grazing system for rearing cattle. Most cattle keepers in the urban and peri-urban areas kept cattle for milk other than beef production. Most respondents in Mbarara district kept more indigenous Ankole cattle than the dairy breeds, while those in Kampala kept more dairy breeds than the indigenous Nganda cattle. Major feed resources used in Kampala and Mbarara districts were agro-industrial by-products, commercial ingredients and crop supply residues. More respondents in Kampala district used both crop supply residues and agro-industrial by-products than their counterparts in Mbarara. In Mbarara district, production and availability of crop-based livestock feed resources heavily relied on the rainfall patterns but in Kampala, the feed resources were independent of the seasons because they were sourced from different parts of the country. The market crop supply residues were widely utilized feed resources in Kampala and Mbarara. Banana peels were the most widely used crop residues, while maize bran was the most widely used agro-industrial by-product. Commercial feed ingredients were the most ingredients utilized by respondents in Kampala (72%) and Mbarara (66%) due to their ability to provide most essential nutrients such as energy and protein. Kampala district had a greater variety and availability of the feed utilizable resources than Mbarara. There is a need to formulate low cost rations based on the available feed resources for testing under the semiintensive beef production systems to identify most practical package for beef production in urban and peri-urban setting.
Nutritional Assessment of Soaked-Boiled-Fermented Jackfruit (Artocarpus Heterophyllus) Seed Meal for Broiler Chickens
(Livestock Research for Rural Development, 2016) Ndyomugyenyi, E.K.; Ebong, J.
Chemical analysis and one feeding trial (0 - 5 weeks) were conducted to assess the nutritional value of Jackfruit seeds (JS) that had been subjected to a combination of soaking, boiling, and fermentation (SBF). Five diets were formulated with the processed Jackfruit seed meal (JSM) representing 0, 8, 16, 24, and 32% of the diet DM.

Secondary sources of data were also reviewed.
Production and Availability of Jackfruit (Artocarpus Heterophyllus) and Java Plum (Syzygium Cumini) Beans for Livestock Feeding in Eastern and Central Regions of Uganda
(Livestock Research for Rural Development, 2014) Ndyomugyenyi, E.K.; Okot, M.W.; Mutetikka, D.
A survey was conducted in the districts of Kampala and Mbale between January and March, 2014 to establish the availability of Jackfruit (JF) and Java plum (JP) beans for poultry feeding. Distribution and productivity of JF and JP trees, interest in the trees, and research that had been done on the trees were also determined. A total of 111 respondents, which included researchers, extension workers and household members were used for the study in two sub-counties from each district. Data were collected using structured questions, observations, and interviews. Secondary sources of data were also reviewed. All respondents knew JP and JF trees; all respondents were interested in the trees, and acknowledged that they discarded the beans as waste. The majority of respondents (72%) indicated that JP and JF trees produced fruits twice a year. More JP trees were found in periurban than rural areas, while the number of JF trees in rural areas did not differ much from those in peri-urban areas. Respondents who had JF trees in their gardens were more (74%) than those with JP trees (58%) but the difference was not significant. The same applied to the number of respondents who purposely grew JF trees being higher (32%) than those who purposely grew JP trees (16%) but the end result of the two groups did not differ much from each other. Of the total respondents who had JP trees in their gardens, 27.6% of them purposely grew the trees using seedlings from nursery beds while 43.2% of the respondents had JF trees grown using the seedlings from the nursery beds. The remaining respondents had JP and JF trees grown naturally in the gardens. The JF trees produced significantly more beans (390kg per tree annually) than JP trees (140kg per tree annually). The annual Jackfruit bean production in the 50 villages covered was 10.3 x 10 2 tonnes while Java plum produced 249 tonnes of beans annually. The major limitations to JP and JF production were caterpillar infestation (34%) and injuries caused by accidental falling of children from JP trees (21.3%). Respondents (83.3%) indicated that little research in Uganda had been conducted on JP beans but some work (12.5%) had been done on JP beans and other parts of JP tree to establish their medicinal properties. To ensure constant production of JP and JF beans; multiplication/breeding of the trees, promoting production of the
Utilisation of Labour among Pig Farmers in Northern Uganda
(African Crop Science Journal, 2020) Mugonya, J.; Kalule, S.W.; Ndyomugyenyi, E.K.
In many sub-Saharan countries, pig (Susscrofa domesticus) production is increasingly an important food security and income generating activity for smallholder farmers. This is attributed to the high prospects for vigilance of the pork market, driven by urbanisation, population growth and dietary transition towards more animal protein per capita. Therefore, increasing pig production is one of the viable pathways to get smallholder farmers out of poverty and food insecurity. Although there are extensive studies about the elements of pig production, such as feeding, breeding and space requirements; little work has been done on distribution of innovation behaviour and the socio-economic factors that influence labour utilisation in the region. The objective of this study was to determine the socio-economic factors that influence labour (family or hired) utilisation and distribution of innovation behaviour among pig farmers in Northern Uganda. Through a cross sectional survey and descriptive analysis, we characterised smallholder pig farmers in the northern Uganda by type of labour used for pig production, and explored the distribution of the dimensions of innovation behaviour (exploration, experimentation, adaptation and modification) among them. Results revealed that young educated farmers with non-farm employment, a smaller household size, belonging to a farmer group and who had many pigs were more likely to use hired labour than those with counter characteristics. There were significant differences in the number of farmers who exhibited the different dimensions of innovation behavior. Therefore, interventions to boost pig production through the use of hired labour should consider the socio-economic differences among farmers which determine labour constraints they face.
