    Commercialisation of Alternative Livestock Feeds Could Save Fish Stocks in Lake Victoria
    (African Journal of Tropical Hydrobiology and Fisheries, 2018) Aggrey, Siya; Kugonza, Donald R.; Muwanika, Vincent
    Increasing livestock production in East Africa requires increased use of fish meal as a source of protein, some of which comes from the Silver Cyprinid (Rastrineobola argentea) in Lake Victoria, which could result in its over-exploitation and affect the survival of other organisms in the lake. The crude protein content of cockroaches (38-76% CP depending on the age) and of other insects is similar to that of fish meal (61.24% CP) and could be a substitute for it, if these insects can be domesticated and used as animal feeds. Non-conventional feeds such as cockroaches, houseflies, termites, earthworms and carabid beetles are used on a small scale by farmers in Uganda who would be willing to use them more if they could be produced on a large scale. There is therefore a need to promote large scale insect breeding so that these alternative protein sources can be integrated into farming systems.

    Growth Characteristics of Sahiwal x Zebu F1 Crossbred Cattle in Uganda
    (International Journal of Livestock Research, 2018) Babigumira, Brian M.; Nabukalu, Robinah G.; Masaba, Joseph K.; Egadu, George W.; Mulindwa, Henry; Oluka, James; Kugonza, Donald R.
    This study assessed the growth of Sahiwal x Zebu crossbreds under low input production conditions in Uganda. Primary data consisted monthly live body weights of 64 Sahiwal first filial generation (F1) crossbred calves born between 2013 and 2015. The herd was on pasture; water provided ad lib and routine control of ticks and worms done. The minimum, average and maximum birth weights for the herd were 15.0, 23.2+ 7.0 and 40.0 kg with a 13% heterotic effect. Birth weight was significantly (P< 0.05) affected by year of birth. Birth weight averages for male and female calves were 24.0+ 7.4 and 22.6+ 7.1 Kg. Average 300-day live body weights for the herd, male and female calves were 85.6, 84.8 and 86.3 kg. Birth weight significantly (P< 0.001) affected average daily gains (AGDs) of the herd. Positive average daily gain significantly (P< 0.05) peaked between 90 to 150 days-of-age. The study recommended targeted supplementary feeding from 90 days-of-age

    Lowland Grazing And Marburg Virus Disease (MVD) Outbreak In Kween District, Eastern Uganda
    (BMC Public Health, 2019) Siya, Aggrey; Bazeyo, William; Tuhebwe, Doreen; Tumwine, Gabriel; Ezama, Arnold; Manirakiza, Leonard; Kugonza, Donald R.; Rwego, Innocent B.
    Uganda is one of the few countries in Africa that has been experiencing outbreaks of viral hemorrhagic fevers such as Ebola, Marburg and Crimean-Congo Hemorrhagic fevers. In 2017 Uganda experienced a Marburg Virus Disease (MVD) outbreak with case fatality rate of 100% in Kween district. Although hunting for wild meat was linked to the MVD outbreak in Kween district, less was reported on the land use changes, especially the changing animal grazing practices in Kween district.Through Makerere University One Health graduate fellowship program with attachment to Uganda Red Cross Society, a study was conducted among the agricultural communities to elucidate the risk behaviors in Kween district that can be linked to the 2017 Marburg disease outbreak.Results show that although a few elderly participants ascribed fatal causes (disobedience to gods, ancestors, and evil spirits) to the MVD outbreak during FGDs, majority of participants linked MVD to settling in caves (inhabited by Fruit Bats) during wet season as upper belts are extensively used for crop production leaving little space for animal grazing. Members also noted side activities like hunting for wild meat during this grazing period that could have predisposed them to Marburg Virus.There is need to integrate One Health concepts within agricultural extension service provision in Uganda so as to enhance the management of such infectious diseases.
