    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.

    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
