Comparative performance and analysis of indigenous pig production systems in Cameroon: constraints and socio-economic characterization in three agro-ecological zones

A socio-economic characterization of the indigenous pig farming systems, performance analysis, and constraints were carried out in three agro-ecological areas Cameroon such as Sudano-Sahelian (SSA), Western highland (WHA) Humid forest with bimodal rainfall Areas (HBA). questionnaire was administered to 157 farmers. The data analyzed using descriptive statistics procedure. results showed that mainly practised by men over forty year old (79.1%), a low level technical supervision having reached primary education (44.6%). production systems HBA SSA are mostly extensive whereas WHA these semi-intensive. piggeries made wooden pens (61.1%). farms more prone feed shortages WHA. animals fed once (45.8%) or twice (38.9%) day. Animals largely unvaccinated (40.8%) not dewormed (59.9%). system least efficient terms gross added value per sow (GVA /sow/year = 398 USD) while (GVA/ sow/year 1305 USD GVA HBA= 1210 USD). This is important for future improvements livestock management, especially Cameroon.
