Pig farming in the municipality of Korhogo is characterised by marked variation in farm structure, management practices, and levels of technical organisation. This study aimed to establish a typology of pig farms in the municipality of Korhogo, northern Côte d’Ivoire. A descriptive and analytical cross-sectional study was conducted from 3 February to 20 April 2025 among 60 pig farms selected by convenience sampling. Data were collected through a structured questionnaire administered during farm visits, complemented by direct observations of housing, equipment, and animal management practices. The information covered farmers’ socio-economic characteristics, production systems, herd structure, feeding and watering practices, reproductive management, health management, biosecurity measures, and production constraints. Multiple Correspondence Analysis was used to identify the main dimensions differentiating farms, and Hierarchical Cluster Analysis using Ward’s method was subsequently applied to the factorial coordinates. The first three factorial axes accounted for 69.68% of the total adjusted inertia. Two major farm groups were identified. The first group represented 81.67% of farms and corresponded mainly to traditional or semi-intensive systems with small herds, limited technical expertise, locally available feed resources, weak reproductive monitoring, and limited biosecurity. The second group, representing 18.33% of farms, showed relatively better-developed infrastructure, more structured management, larger herds, and stronger technical organisation. These findings demonstrate substantial heterogeneity among pig farms in Korhogo and support differentiated approaches to farm support and development.
