Aim: 
                              To study the factors affecting pig production in 
                              Nangabo Sub-County, Wakiso District, Central 
                              Uganda. Materials and Methods: A total of 
                              11% (1350/12783) of all households in the Nangabo 
                              Sub-County kept pigs. The systematic sampling 
                              technique was used to complete the list of all pig 
                              farming households. This was done by taking 10th 
                              farming household until 10% of all the farming 
                              households were sampled. A total of 135 farmers 
                              were interviewed with semi- structured 
                              questionnaire. Questionnaire data was entered into 
                              Microsoft Excel worksheet and trans-ferred into 
                              Statistical Package for Social Scientists. 
              
              
                               
                              Results: Results indicated that 49.6 % of the 
                              pigs were raised in the semi-intensive system 
                              while 31%, 12% and 8% of the farmers kept pigs on 
                              intensive, tethering and free range rearing 
                              systems respectively. Farmers that raised their 
                              pigs on what is hereby referred to as 
                              semi-intensive and intensive management systems 
                              allowed their pigs up to five and two hours of 
                              open foraging respectively. Ninety eight percent 
                              of the farmers provided housing to their pigs and 
                              the commonest pig houses were local mud houses and 
                              a few of them were tree shades. Majority of 
                              farmers (85.2%) watered their pigs at least once a 
                              day. The major factors limiting pig production 
                              were; diseases and parasites mainly helminthosis 
                              and African swine fever (ASF). Others included; 
                              high costs of inputs, lack of capital, unstable 
                              availability of feed resources, inadequate 
                              advisory services and feed price fluctuation 
                              (maize bran, sow and weaner), lack of good quality 
                              breeding stock, poor and unorganized marketing, 
                              lack of enough land, high costs of veterinary 
                              medicines and inability to keep records. 
                              Additionally, lack of enough water and 
                              uncontrolled pig movement grossly limited the pig 
                              production in Wakiso district. Most Ugandans keep 
                              their pigs in peri-urban areas of Uganda. It was 
                              however, noted that there were important 
                              limitations for pig production in the country. To 
                              improve pig production and reduce animal protein 
                              deficit, knowledge on constraints to pig 
                              production was important to inform pig sector 
                              promotion stakeholders. Conclusion: 
                              Limitations to pig farming including parasites and 
                              diseases, ASF, nutritional deficiencies, high cost 
                              of inputs like building materials, drugs and 
                              veterinary services, inadequate capital and 
                              failure of farmers to access credit services, 
                              expensive feeds among others were identified and 
                              should be addressed to meet national animal 
                              protein requirements.
