    Characterization of smallholder pig production systems in Uganda: constraints and opportunities for engaging with market systems
    (African Association of Agricultural Economics, 2013) Ouma, Emily; Dione, Michel; Lule, Peter; Rosel, Kristina; Pezo, Danilo
    Pig production has increasingly become an important activity, especially among smallholder farmers in Uganda in the past three decades as evidenced by a dramatic rise in pig population from 0.19 to 3.2 million. This is linked to the rise in demand for pork due to preference changes among other factors. Per capita consumption of pork has been estimated at 3.4 kg/person/year representing a ten-fold increase in the last 30 years. Pigs are important assets for the poor smallholders in Uganda generating income for meeting planned and emergency household financial needs. Despite its importance, the smallholder pig systems are faced with a number of productivity and market related constraints ranging from diseases, poor nutrition and poorly organized markets. Strong growth opportunities to improve smallholder pig systems exist if the constraints are minimized. However the constraints and opportunities vary among smallholder producers as they are not a homogenous group and are affected by various factors. This paper applies a cluster analysis to characterize smallholder pig production systems into typologies in three districts in Uganda by utilizing village level data from 35 villages. The paper further explores the constraints and opportunities for the different typologies to engage with output and input market systems. The paper concludes that different interventions are necessary to improve market linkages with the smallholder pig production systems due to their varying differences in terms of farmers’ cooperative involvement, institutional linkages and intensification related indicators.

    Governance structures in smallholder pig value chains in Uganda: constraints and opportunities for upgrading
    (International Food and Agribusiness Management Review, 2017) Ouma, Emily; Ochieng, Justus; Dione, Michel; Pezo, Danilo
    This paper analyses governance structures in Uganda’s smallholder pig value chains by applying the New Institutional Economics framework. It utilises cross sectional and qualitative survey data from randomly selected pig value chain actors in 4 districts. A multinomial logit model is applied to assess the determinants of vertical integration among pig traders. The findings indicate that most relationships at the pig production node of the value chain are based on spot market governance structures supported by personal relationships and trust. Live pig traders are mostly vertically integrated. High integration levels of the pig traders are positively influenced by access to market information, value of investments in the value chain, and dedicated asset specificity in terms of backyard slaughter premises. Upgrading opportunities in the value chain in the form of value addition strategies, policy implementation and promotion of business models that link producer organisations to quality inputs and service suppliers through contractual arrangements are identified.

    Knowledge, attitudes and practices of pork consumers in Uganda
    (Global Food Security, 2019) Roesela, Kristina; Ejobi, Francis; Dione, Michel; Pezo, Danilo; Ouma, Emily; Kungu, Joseph; Clausen, Peter-Henning; Grace, Delia
    Pig production is thriving in Uganda and the demand for pork is increasing, therefore offering potential for increased income from pig production and marketing. The consumers’ preferences determine and potentially drive this demand but are largely unknown in the context of Uganda. As part of a multi-disciplinary assessment of smallholder pig value chains we investigated these preferences in one of the four thematic subgroups with 292 smallholder pig farmers. In addition, 79 consumers in Kampala, the main pork market outlet in Uganda, were included. Using participatory methods and considering that pig keepers are also consumers, we describe drivers for and taboos around eating pork, the role of pork in peoples’ diets compared to other livestock-derived foods, important attributes when buying pork, the risk of pig feeds competing with human food as well as knowledge, attitudes and practices around pig zoonoses.

    Participatory assessment of animal health and husbandry practices in smallholder pig production systems in three high poverty districts in Uganda
    (Preventive veterinary medicine, 2014) Dione, Michel M.; Ouma, Emily A.; Roesel, Kristina; Kungu, Joseph; Lule, Peter; Pezo, Danilo
    While animal health constraints have been identified as a major limiting factor in small-holder pig production in Uganda, researchers and policy makers lack information on the relative incidence of diseases and their impacts on pig production. This study aimed to assess animal health and management practices, constraints and opportunities for intervention in smallholder pig value chains in three high poverty districts of Uganda.Semi-qualitative interview checklists through Focus Group Discussions (FGDs) were administered to 340 pig farmers in 35 villages in Masaka, Kamuli and Mukono districts.Quantitative data was obtained during the exercise through group consensus. Results of FGDs were further triangulated with secondary data and information obtained from key informant interviews. Findings show that pig keeping systems are dominated by tethering and scavenging in rural areas. In peri-urban and urban areas, intensive production systems are more practiced, with pigs confined in pens. The main constraints identified by farmers include high disease burden such as African swine fever (ASF) and parasites, poor hous-ing and feeding practices, poor veterinary services, ineffective drugs and a general lack of knowledge on piggery management. According to farmers, ASF is the primary cause of pig mortality with epidemics occurring mainly during the dry season. Worms and ectopara-sites namely; mange, lice and flies are endemic leading to stunted growth which reduces the market value of pigs. Diarrhoea and malnutrition are common in piglets. Ninety-three percent of farmers say they practice deworming, 37% practice ecto parasite spraying and 77%castrate their boars. Indigenous curative treatments include the application of human urine and concoctions of local herbs for ASF control and use of old engine oil or tobacco extractst o control ectoparasites. There is a need for better technical services to assist farmers with these problems.

    Qualitative analysis of the risks and practices associated with the spread of African swine fever within the smallholder pig value chains in Uganda
    (Preventive veterinary medicine, 2016) Dione, Michel; Ouma, Emily; Opio, Felix; Kawuma, Brian; Pezo, Danilo
    tA study was undertaken between September 2014 and December 2014 to assess the perceptions of smallholder pig value chain actors of the risks and practices associated with the spread of African swine fever (ASF) disease within the pig value chains. Data was collected from 136 value chain actors and 36key informants through 17 group discussions and two key informant interview (KII) sessions respectively using Participatory Rural Appraisal (PRA) tools.Results from this study revealed that according to value chain actors and stakeholders, the transport-ing, slaughtering, and collecting/bulking nodes represent the highest risk, followed by the inputs andservices (feeds and drugs) supply nodes. The processing, whole sale and consumption nodes represented the lowest risk. Value chain actors are aware of the disease and its consequences to the pig industry,however biosecurity measures are poorly implemented at all nodes. As for the causes, value chain actors pointed to several factors, such as inadequate knowledge of mechanisms for the spread of the disease,poor enforcement of regulations on disease control, and low capacities of actors to implement biosecurity measures, amongst others. Although traders, butchers and veterinary practitioners accepted that they played an important role in the spread of the virus, they did not perceive themselves as key actors in the control of the disease; instead, they believed that only farmers should adopt biosecurity measures on their farms because they keep the pigs for a longer period. Most of the recommendations given by the value chain actors for controlling and preventing ASF disease were short term, and targeted mainly pig producers. These recommendations included: the establishment of live pig collection centres so that traders and brokers do not have to directly access pig farms, capacity building of value chain actors on application of biosecurity, enactment and enforcement of by-laws on live pig movements and establishment of operational outbreak reporting mechanism at district level. Long term recommendations included the development of a vaccine, as well as pen-side diagnostic tests. This study suggests that interventions to control ASF disease through application of biosecurity measures should target all value chain nodes, while putting more emphasis on post-farm nodes especially the trading.

    Sero-prevalence of Taenia Solium cysticercosis in rural and urbansmallholder pig production settings in Uganda
    (Acta tropica, 2017) Kungu, Joseph M.; Dione, Michel M.; Ejobi, Francis; Harrison, Leslie J.S.; Poole, Jane; Pezo, Danilo; Grace, Delia
    The pork tapeworm, Taenia solium, is prevalent in Uganda although the prevalence has not been deter-mined in all areas of the country. A cross-sectional study, to determine the sero-prevalence of the parasitein pigs kept under rural and urban production settings, was carried out in three Ugandan districts, Masaka, Mukono and Kamuli. Serum samples from 1185 pigs were tested for the presence of T. solium cysticer-cosis antigen using the HP10 antigen-ELISA (Ag-ELISA) and the ApDia Ag-ELISA assays. Using parallel interpretation of the two tests showed lower levels of observed prevalence of T. solium in rural pro-duction settings (10.8%) compared to urban (17.1%). Additionally, Maximum Likelihood Estimation forevaluating assays in the absence of a gold standard, using TAGS on the R platform, estimated the true sero-prevalence to be lower in rural production setting, 0.0% [0.0–3.2%; 95% confidence interval (CI)] thanin urban production setting, 12.3% (4.2–77.5% CI). When the sensitivity/specificity (Se/Sp) of the assays were estimated, assuming conditional independence of the tests, HP10 Ag-ELISA was more sensitive and specific [(Se = 53.9%; 10.1–100% CI), (Sp = 97.0%; 95.9-100% CI)] than the ApDia assay [(Se = 20.2%;1.5–47.7% CI), (Sp = 92.2%; 90.5–93.9% CI)]. Subject to parasitological verification, these results indicate there may be a need to implement appropriate control measures for T. solium in the study areas.

    Serological and molecular investigation for brucellosis in swine in selected districts of Uganda
    (Tropical Animal Health and Production, 2016) Erume, Joseph; Roesel, Kristina; Dione, Michel M.; Ejobi, Francis; Mboowa, Gerald; Kungu, Joseph M.; Akol, Joyce; Pezo, Danilo; El-Adawy, Hosny; Melzer, Falk; Elschner, Mandy; Neubauer, Heinrich; Grace, Delia
    Brucellosis is a notifiable zoonotic disease affecting livestock, humans, and wildlife in Uganda. Pigs can be infected with human pathogenic Brucella suis biovars 1 and 3 and can be a significant source of brucellosis for humans. Uganda has a rapidly growing pig population, and the pork consumption per capita is the highest in East Africa. The objective of this work was to determine the seroprevalence of brucellosis in Ugandan pigs. A cross-sectional serosurvey of pigs was conducted in three of the major pig-keeping districts in Uganda (Masaka (n= 381 samples), Mukono (n = 398), and Kamuli (n = 414)). In addition, pigs originating from these districts were sampled in the major pig abattoir in Kampala (n =472). In total, 1665 serum samples were investigated by serological and molecular tests. Only three putative brucellosis-positive samples were detected serologically using indirect ELISA. These sera were found negative for Brucella antibodies by CFT; however, two had antibodies against Yersinia enterocolitica as determined by SAT. Presence of antibodies against Yersiniae was confirmed by Y. enterocolitica antibody-specific ELISA. The two Yersiniae ELISA-positive samples were brucellosis negative using real-time PCR. We tested additional 142 sera from the 1665 samples with real-time PCR. All tested negative. Under this type of production system, we expect a maximum B. suis prevalence of less than 1 % at 95 % confidence level, and therefore, the risk of acquiring brucellosis from the pigs or their products is negligible. However, pigs may harbor the zoonotic Y. enterocolitica. This is the first study to investigate the occurrence of brucellosis in pigs in Uganda and the first study to report Y. enterocolitica antibodies in swine in Uganda.

    Smallholder pig value-chain assessment in Uganda: Results from producer focus group discussions and key informant interviews
    (ILRI Project Report, 2015) Ouma, Emily; Dione, Michel; Lule, Peter; Pezo, Danilo; Marshall, Karen; Roesel, Kristina; Mayega, Lawrence; Kiryabwire, David; Nadiope, Gideon; Jagwe, John
    The CGIAR Research Program on Livestock and Fish identified the smallholder pig value chain in Uganda as a highpotential target to translate research into major interventions that stimulate pro-poor transformation and generate benefits at scale. The program began by engaging with research and development partners, analysing the pig value chain and its policy environment as well as characterizing smallholder pig production and marketing practices in Uganda. These activities were done as part of a project entitled ‘Catalysing the emerging smallholder pig value chains in Uganda to increase rural incomes and assets’, which was funded by the International Fund for Agricultural Development (IFAD) and the European Commission (EC).
