Socioeconomic characteristics and adaptation strategies of pig farmers in Ika south local government area, delta state, Nigeria

Introduction

The livestock sector occupies a strategic position in Nigeria's agricultural economy, contributing significantly to employment generation, income creation, and food security. Within this sector, pig production has emerged as an important enterprise for smallholder farmers, particularly in southern Nigeria where cultural and religious restrictions are less pronounced compared to predominantly Muslim northern regions. The Food and Agriculture Organization (FAO, 2021) [9] reports that pig production is among the fastest-growing livestock sectors globally, with developing countries accounting for most of this growth. In Nigeria, pig population and production have expanded considerably over recent decades, driven by increasing demand for animal protein, urbanization, and recognition of pigs' biological efficiency in converting feed to meat (Ogunniyi and Omoteso, 2021; Ajala et al., 2017) [14,2] . Pig production offers several comparative advantages that make it particularly suitable for smallholder farmers. Pigs possess high prolificacy, with sows capable of producing two litters per year with 8-12 piglets per litter under good management (Holness, 2017; Serres, 2019) [10,18] . They exhibit superior feed conversion ratios compared to ruminants, requiring approximately 3-4 kg of feed to produce 1 kg of body weight gain (Moseri et al. 2023) [11] . Pigs reach market weight in 6-8 months compared to 18-24 months for cattle, enabling faster capital turnover (Ezeibe, 2010) [7] . Additionally, pigs are omnivorous and can utilize diverse feed resources including agricultural by-products, household waste, and forage, reducing dependence on expensive commercial feeds (Okoli, 2018; Babatunde and Fetuga, 2020) [15,4] . Despite these advantages, pig production in Nigeria faces numerous challenges that constrain productivity and profitability. Studies by Adesehinwa et al. (2013) [1] , Ajala (2017) [3] , and Ezeibe (2018) [8] have documented various constraints including inadequate access to quality breeding stock, high feed costs, limited credit availability, insufficient veterinary services, disease outbreaks, inadequate extension support, poor infrastructure, and in some contexts, religious and cultural biases against pork consumption. The severity and nature of these constraints vary across different agroecological zones, production systems, and farmer categories, necessitating localized research to inform context specific interventions. Understanding the socioeconomic characteristics of pig farmers is fundamental to designing appropriate development interventions and support systems. Socioeconomic variables such as age, education, farming experience, household size, income level, and access to resources significantly influence www.extensionjournal.com farmers' management practices, technology adoption, adaptation capacity, and overall farm performance (Adesehinwa et al., 2003; Bamiro, 2008) [1,5] . For instance, younger farmers may be more willing to adopt innovations but lack capital and experience, while older farmers possess experience but may be risk averse. Educated farmers typically demonstrate greater capacity to process information, adopt technologies, and manage production challenges effectively (Oladele, 2012; Ajala, 2017) [16,2] . Farming experience provides accumulated knowledge and skills essential for decision making, while household size influences labor availability and consumption pressure on farm income. Ika South Local Government Area of Delta State presents an interesting context for examining pig production dynamics. Located in southern Nigeria's humid tropical zone, the area benefits from favorable climate for crop and livestock production but also faces environmental challenges including high temperatures, humidity, and seasonal rainfall variations. The area's population of over 160,000 inhabitants includes diverse socioeconomic groups ranging from subsistence farmers to commercial agricultural entrepreneurs, civil servants, and business owners. This socioeconomic diversity creates varied contexts for pig production, from small-scale backyard operations with 2-5 pigs to medium and large-scale commercial enterprises with 50-100 breeding sows. Pig farming in Ika South LGA operates within a broader context of agricultural transformation occurring across Delta State and southern Nigeria. Increasing urbanization, rising incomes, and dietary diversification are driving growing demand for animal protein, particularly pork which is culturally acceptable and increasingly consumed in urban centers (Nwobodo, 2017) [13] . Simultaneously, farming systems are evolving from traditional extensive scavenging systems toward semi-intensive and intensive production utilizing improved breeds, commercial feeds, and better housing (Moseri et al. 2018) [11] . These transformations create both opportunities and challenges for farmers, requiring adaptation in management practices, market engagement, and production strategies. Previous research on pig production in Nigeria has primarily focused on production economics (Ezeibe, 2010; Ogunniyi and Omoteso, 2021) [7,14] , technical efficiency (Bamiro, 2008) [5] , marketing systems (Nwobodo, 2017) [13] , and specific technical aspects such as nutrition (Tewe and Adesehinwa, 2015) [19,1] and breed performance (Okoli, 2018) [15] . While these studies provide valuable insights, limited research has comprehensively examined the socioeconomic profiles of pig farmers, their information sources, adaptation strategies employed, and constraints faced within specific local contexts like Ika South LGA. Understanding these dimensions is critical for developing farmer centered interventions that build on existing capacities while addressing genuine constraints. Despite the recognized potential of pig production to contribute to food security, income generation, and rural livelihoods in Delta State, several challenges hinder optimal sector development in Ika South Local Government Area. First, there is inadequate empirical documentation of the socioeconomic characteristics of pig farmers in the area. While anecdotal evidence suggests pig farming engages diverse categories of people from small-scale subsistence farmers to medium and large-scale commercial operators, systematic data on farmers' demographic profiles, educational backgrounds, farming experience, household characteristics, and economic status are lacking. Without this baseline understanding of who pig farmers are, development programs and extension services cannot effectively target interventions to match farmers' capacities, needs, and circumstances. Questions remain about whether pig farmers are predominantly young or mature, educated or with limited schooling, experienced or novice, resource poor or relatively well-endowed in all factors that significantly influence appropriate support strategies. Second, pig farmers in Ika South LGA operate under challenging conditions including tropical heat stress, limited access to inputs, inadequate extension support, and economic constraints, yet their responses to these challenges have not been systematically documented. Farmers undoubtedly develop and employ various adaptation and coping strategies based on indigenous knowledge, peer learning, and practical experience. However, these strategies whether related to breed selection, housing design, feeding practices, disease management, or marketing remain largely undocumented. Understanding what adaptation strategies farmers currently employ, which strategies are most widely adopted, and how effective these strategies are would provide valuable insights for extension programs and farmer training. Additionally, identifying gaps between farmers' current practices and recommended practices would highlight priority areas for intervention. Furthermore, information sources through which farmers acquire knowledge about pig production practices have not been documented for the study area. Understanding whether farmers rely primarily on formal extension services, fellow farmers, private input dealers, mass media, or other channels is essential for designing effective communication strategies for disseminating improved technologies and practices. The apparent mismatch between limited extension coverage and continuing production suggests farmers are accessing information through alternative channels that warrant investigation. Thus, this study examined the socioeconomic characteristics and adaptation strategies of pig farmers in Ika South Local Government Area of Delta State, Nigeria.

Methodology

The study was conducted in Ika South Local Government Area, Delta State, Nigeria. Ika South LGA covers approximately 463 square kilometers in the northern part of Delta State, with Agbor serving as the administrative headquarters. The estimated population exceeds 163,000 inhabitants distributed across 16 major communities including Agbor-obi, Alihame, Omumu, Alisimie, Ozanogogo, Emuhu, Aliagwa, Ewuru, Ekuku-Agbor, Oki, Agbor-Nta, Aliokpu, Alisor, Abavo, Alizomor, and Idumoza. The area is predominantly inhabited by Ika-speaking people, an Igbo sub-group. The economy is based on agriculture (crop farming and livestock production), trading, transportation, and civil service employment. The tropical climate features distinct wet (April-October) and dry (November-March) seasons with mean annual temperature of 26-28°C and rainfall of 1800-2500mm. The study employed a descriptive cross-sectional survey research design. This design was appropriate for collecting www.extensionjournal.com data from a sample of pig farmers at a single time point to describe their characteristics, practices, and experiences without experimental manipulation (Check and Schutt, 2012) [6] . The target population comprised all pig farmers in Ika South LGA. A multi-stage sampling procedure was used to select respondents. First, 16 communities with active pig farming were purposively selected. Second, one pig farm was randomly selected from each community. Third, five respondents (farm owners, managers, or experienced workers) were randomly selected from each farm, yielding 80 total respondents. Data were collected using structured questionnaires containing both closed-ended and open-ended questions. The questionnaire comprised four sections: Section A: Sociodemographic information (gender, age, marital status, education, household size, farming experience); Section B: Enterprise characteristics (farming system, feed sources, management practices, credit access, income); Section C: Information sources and adaptation strategies; Section D: Production enhancement strategies and limiting factors. Likert scales (Strongly Agree to Strongly Disagree; Very Important to Not Important) were used for perception and rating items. Face and content validity were established through expert review by specialists in agricultural education, extension, and animal science. Test-retest reliability method yielded correlation coefficients exceeding 0.60, indicating acceptable reliability. Data were collected by the researcher with assistance from trained enumerators familiar with local language and culture. Questionnaires were administered to literate respondents while interviews were conducted with non-literate farmers. Data collection occurred during farm visits at times convenient to farmers. Data were analyzed using descriptive statistics (frequencies, percentages, means, standard deviations) calculated using Statistical Package for Social Sciences (SPSS). For Likertscale items on 4-point scales, mean scores ≥2.50 indicated agreement/importance while means <2.50 indicated disagreement/lack of importance.

Results

Table 1 presents comprehensive socioeconomic and enterprise profiles of pig farmers in Ika South LGA. Gender distribution reveals strong male dominance (81.3%) compared to females (18.8%). This masculine predominance in pig farming aligns with broader patterns in Nigerian livestock production documented by Ajala et al. (2017) [2] and Ogunniyi and Omoteso (2021) [14] , attributing this gender disparity to cultural norms assigning livestock management primarily to men, greater male access to productive resources including land and credit, and physical demands of pig farming activities such as pen construction, waste management, and handling large animals. Nevertheless, the 18.8% female participation indicates women's growing involvement in pig production, potentially reflecting changing gender roles, female-headed households, or women's entrepreneurial initiatives in livestock enterprises. Age distribution indicates concentration in mature productive years, with 45.0% in the 41-45 age bracket and 37.5% in the 36-40 range. The mean age of 41.2 years suggests pig farming attracts middle-aged individuals rather than youth or elderly populations. This age profile has important implications for innovation adoption, risk-taking behavior, and sector sustainability. Middle-aged farmers typically possess accumulated capital, experience, and established market networks while maintaining physical capacity for farm operations. However, limited youth participation (only 8.8% aged ≤35 years) raises concerns about generational succession and long-term sector viability, reflecting broader rural youth migration patterns documented across Nigerian agriculture. Marital status data shows majority of farmers are married (62.5%), with smaller proportions single (21.3%) or divorced/widowed (16.3%). Marriage correlates with household stability, labor availability through family members, and responsibility for dependents that motivates income generation. Married farmers often benefit from spousal support in farm activities, particularly in feeding, cleaning, and record-keeping tasks commonly performed by wives in Nigerian farming households. Educational attainment is notably high, with 95.0% having formal education. Secondary education predominates (55.0%), followed by primary (37.5%) and tertiary (7.5%), while only 5.0% lack formal schooling. This educational profile substantially exceeds typical rural farming populations in Nigeria and suggests pig production attracts relatively educated individuals. Education enhances capacity to access and process technical information, adopt improved practices, maintain farm records, and engage effectively with markets and institutions. The predominance of secondary education indicates farmers possess basic literacy and numeracy essential for commercial farming but may benefit from technical training in specialized pig production aspects. Household size averages 13.6 members, considerably exceeding Nigerian national average of 4.9 persons per household (NBS, 2020). Large household sizes reflect extended family systems prevalent in southeastern Nigeria, where households incorporate nuclear family, aging parents, unmarried siblings, and dependent relatives. While large households provide potential farm labor, they also impose substantial consumption pressure on farm income, potentially limiting capital available for farm investment and technology adoption. Farming experience averages 19.1 years, indicating substantial accumulated knowledge and practical expertise. Experience distribution shows relatively even spread: 23.9% with ≤10 years, 23.9% with 11-20 years, 20.1% with 21-30 years, and substantial proportions with >30 years of experience. Long farming tenure provides valuable insights into seasonal production patterns, disease management, breeding practices, and market dynamics. However, long experience with traditional methods may also create resistance to new technologies, particularly when farmers have developed successful coping mechanisms within existing systems. Regarding enterprise characteristics, farm size distribution reveals predominance of small-scale operations, with 71.5% maintaining 1-50 pigs and 27.7% with 51-100 pigs. Only 1.3% operate larger enterprises exceeding 100 animals. This small-scale dominance reflects typical African pig production patterns characterized by limited capital, land www.extensionjournal.com constraints, and market access challenges that prevent enterprise expansion. Piggery enterprise types show 61.3% conducting all operations (breeding, farrowing, piglet rearing, and finishing), 27.5% combining farrowing and finishing, and 11.3% specializing in farrowing only. Integrated operations allow farmers to capture value across production stages but require diverse skills, sustained feed supply, and adequate facilities. Specialization, though less common, enables focused management and may reduce capital requirements. Feed sources reveal 51.3% combining commercial and farmmixed feeds, 22.5% using exclusively farm-mixed feeds, 15.0% utilizing kitchen remnants, and 11.3% relying solely on commercial feeds. Predominance of mixed feeding strategies reflects farmers' efforts to balance nutritional requirements with cost management in context of expensive commercial feeds. Farm-mixing allows incorporation of locally available ingredients including crop residues, processing by-products, and household waste, reducing feed costs while maintaining adequate nutrition. Management systems show overwhelming dominance of semi-intensive practices (81.3%) compared to extensive systems (18.8%). Semi-intensive management involves housing with controlled access to outdoor areas, supplementary feeding beyond foraging, and some disease prevention measures. This system balances investment requirements, labor demands, and productivity outcomes, making it appropriate for smallholder contexts. The nearabsence of fully intensive systems reflects capital and technical constraints limiting adoption of sophisticated housing, climate control, and complete confinement systems.

Credit access remains severely limited, with 81.3% lacking access to formal credit. Among those obtaining capital, 52.5% depend on loans (presumably informal sources given limited formal credit access) and 45.0% rely on alternative sources including personal savings, family contributions, and livestock sales. Limited credit access severely constrains farm expansion, technology adoption, and ability to weather production challenges. This finding echoes broader agricultural finance challenges in Nigeria where smallholder farmers face collateral requirements, high interest rates, and institutional barriers limiting formal credit access. Annual income distribution shows remarkable concentration in the ₦301,000-400,000 range (77.5%), with smaller proportions earning ₦201,000-300,000 (10.0%), ₦401,000-500,000 (8.8%), or outside these ranges. This income clustering suggests relatively standardized production scales and market conditions across farms. However, these income levels, equivalent to approximately $600-800 USD annually at prevailing exchange rates, indicate pig farming provides modest rather than substantial income, likely supplementing rather than replacing other livelihood activities. Extension access shows 55.0% lack contact with extension services while 45.0% have some access. This limited extension coverage reflects broader agricultural extension challenges in Nigeria including insufficient extension personnel, poor funding, inadequate transportation, and weak linkages between research, extension, and farmers. Limited extension access forces farmers to rely on alternative information sources and indigenous knowledge for production decisions. Table 2 reveals diverse information sources accessed by farmers, with fellow farmers overwhelmingly dominant (95.0%). Peer-to-peer knowledge exchange through farmerto-farmer communication represents primary learning mechanism, reflecting social learning processes where farmers observe, discuss, and adopt practices from successful colleagues. This horizontal information flow compensates for weak formal extension but may perpetuate suboptimal practices if peer networks lack exposure to improved technologies. Livestock dealers emerge as second most important source (73.3%), highlighting private sector's role in technology dissemination. Input suppliers including feed dealers, equipment vendors, and livestock traders provide technical advice alongside product sales, creating informal extension system driven by commercial relationships rather than public provision. However, dealer advice may prioritize product sales over farmers' best interests, potentially compromising technical quality. Extension agents reach only 45.0% of farmers despite public extension system's mandate for universal coverage. This limited reach reflects systemic extension challenges and suggests substantial unmet demand for technical support. Mass media (35.0%) and internet/social media (23.8%) serve modest proportions, with low internet access indicating digital divide limiting online information access in rural areas. Veterinary officers (22.5%), print materials (15.0%), and NGO projects (10.0%) serve even smaller proportions, representing supplementary rather than primary information channels. 4 presents farmers' ratings of potential production enhancement strategies. Special credit schemes and priority lending both achieve highest importance ratings (mean=3.50), reflecting severe financial constraints farmers face. Access to affordable credit would enable investment in improved breeds, feeds, housing, and equipment currently beyond farmers' reach. Credit importance transcends production stages, affecting breeding stock acquisition, feed procurement, facility construction, and operational expenses. Input subsidization ranks third (mean=3.20), addressing high costs of commercial feeds, veterinary products, and equipment that consume substantial farm income. Government subsidies reducing input costs would improve profitability and enable adoption of recommended production practices currently economically prohibitive. Improved breed provision (mean=3.18) reflects farmers' recognition that genetic improvement represents fundamental productivity enhancement pathway, yet quality breeding stock remains largely inaccessible. Enhanced extension services (mean=3. 15), training in modern techniques (mean=3.10), and improved veterinary services (mean=3.08) cluster together, indicating strong demand for technical support across production domains. These moderate-to-high ratings suggest farmers recognize knowledge gaps and technical skill deficiencies limiting production optimization. Cooperative formation (mean=3.00), market information systems (mean=2.95), and infrastructure development (mean=2.88), while valued, receive lower priority ratings possibly because farmers perceive more immediate needs in credit, inputs, and technical knowledge. Table 5 identifies multiple interrelated constraints limiting farmers' adaptation capacity. Lack of improved production technologies (95.0%) emerges as most pervasive constraint, encompassing limited access to modern breeding stock, efficient feeding systems, climate-controlled housing, waste management technologies, and precision production tools. Technology gaps prevent farmers from implementing recommended practices even when aware of their benefits. Poor extension information (77.5%) reflects inadequate public extension provision discussed earlier, leaving farmers without reliable technical guidance for production decisions. Limited improved breed access (76.3%) constrains genetic improvement possibilities, forcing reliance on unimproved local stock or informal breeding networks of uncertain quality. High labor costs (73.8%) create operational challenges especially for larger farms requiring hired labor for feeding, cleaning, and animal handling tasks. Inadequate capital/credit (72.5%) creates binding financial constraints limiting investment in all production aspects. High feed costs (71.3%) represent ongoing operational challenge as feed typically constitutes 70-80% of pig production costs, making profitability highly sensitive to feed prices. Poor veterinary services (67.5%) limit disease prevention and treatment capacity, increasing mortality and morbidity losses. Market information deficiencies (60.0%) prevent optimal marketing decisions regarding timing, pricing, and buyer selection. Poor infrastructure (56.3%) including roads, electricity, and water supply increases production costs and marketing challenges. Disease outbreaks (52.5%) cause periodic production losses despite farmers' best prevention efforts. Cultural/religious constraints (47.5%) create market limitations in predominantly Muslim areas and social stigma in some communities. Land scarcity (43.8%) restricts farm expansion possibilities in increasingly populated areas.

Discussion

The study's findings reveal pig farming in Ika South LGA as practiced predominantly by middle-aged, married, educated www.extensionjournal.com males with substantial farming experience but operating under significant resource constraints. The demographic profile suggests pig production attracts individuals with maturity, responsibility, and some education who view pig farming as viable income source within diversified livelihood portfolios. However, the concentration in middle age raises sustainability concerns as youth largely avoid pig farming, potentially due to migration to urban areas, perceived social status issues, or limited capital for entry, consistent with the male-dominated, middle-aged demographic profile of pig producers reported by Ajala et al. (2017) [3] and Ogunniyi and Omoteso (2021) [14] . High educational attainment among pig farmers contradicts common assumptions about livestock farming as refuge for uneducated rural populations. Instead, findings suggest educated individuals recognize pig production's economic potential and actively engage despite challenges. This educational capital represents important resource for extension and development programs, as literate farmers can process written materials, adopt complex technologies, and engage formal institutions more effectively than non-literate counterparts, supporting the link between education and innovation adoption established by Oladele (2012) [16] and Ajala (2017) [2] . The predominance of semi-intensive management reflects practical compromise between resource availability and production intensity aspirations. Semi-intensive systems enable some production control and productivity improvements over extensive scavenging while avoiding capital-intensive requirements of fully intensive systems. However, this intermediate position may also represent transition point where farmers aspire toward intensive production but lack resources for full transformation, suggesting need for targeted support facilitating this transition, a pattern consistent with the shift from extensive to semi-intensive systems documented by Moseri et al. (2018) [11] . Limited credit access emerges as critical constraint cutting across all production aspects. Without adequate financing, farmers cannot invest in improved breeds, quality feeds, better housing, veterinary care, or farm expansion regardless of technical knowledge or motivation. Credit constraint particularly affects youth and women who typically have less accumulated capital and face greater collateral barriers in formal financial markets. Addressing credit access through specialized agricultural finance programs, collateral-free lending schemes, or cooperative credit systems could substantially enhance production potential, echoing recommendations from Adesehinwa et al. (2013) [1] and Bamiro (2008) [5] on financing constraints in pig enterprises. Information source patterns reveal informal knowledge networks' predominance filling gaps left by inadequate formal extension. While peer learning enables practical knowledge sharing and social support, it also risks perpetuating suboptimal practices if farmer networks lack exposure to research-based innovations. Livestock dealers' prominent role as information sources creates potential conflicts of interest where commercial considerations may outweigh farmers' best interests. Strengthening public extension and creating mechanisms for reliable technical information dissemination independent of commercial agendas would improve decision quality, corroborating the reliance on informal peer and dealer networks noted by Ajala et al. (2017) [3] and Ogunniyi and Omoteso (2021) [14] . Adaptation strategies farmers employ demonstrate considerable indigenous innovation and practical problemsolving. Wallowing provision, strategic roofing choices, breed selection, and feeding adjustments show farmers actively responding to environmental and economic constraints within their resource means. However, limited adoption of more sophisticated strategies like sprinkler systems or intensive health management suggests capital and knowledge constraints prevent accessing full range of available adaptations. Extension programs could validate and build upon existing farmer innovations while introducing accessible complementary technologies, particularly around breed selection where Okoli (2018) [15] similarly emphasized the role of breed choice in tropical performance outcomes. Enhancement strategy ratings clearly prioritize financial support and input subsidization over training and institutional development. While understandable given severe resource constraints farmers face, this priority pattern risks overlooking importance of knowledge, skills, and institutional capacity that enable effective resource utilization. Balanced development programs should address both financial access and technical capacity simultaneously, recognizing that credit without knowledge produces limited impact while knowledge without capital enables only theoretical understanding. Limiting factors identified by farmers paint comprehensive picture of multidimensional constraints spanning technological, informational, economic, infrastructural, and market dimensions. This constraint multiplicity means single-intervention approaches will likely achieve limited impact. Instead, comprehensive support packages addressing multiple constraint dimensions simultaneously would better facilitate sustainable pig production development. Priority should focus on constraints affecting largest farmer proportions and those creating bottlenecks limiting other improvements, a multidimensional constraint profile similarly documented by Adesehinwa et al. (2013) [1] and Ezeibe (2018) [8] in other Nigerian pig-producing regions.

Conclusion

This study examined socioeconomic characteristics and adaptation strategies of pig farmers in Ika South Local Government Area, Delta State, Nigeria. Findings reveal pig farming attracts predominantly middle-aged, married, educated males with substantial experience operating smallto-medium scale farms under semi-intensive management systems. Farmers demonstrate considerable practical knowledge and indigenous innovation through diverse adaptation strategies addressing heat stress, feed costs, and production challenges. However, they face severe constraints including limited improved technologies, inadequate extension support, restricted breed access, high input costs, insufficient credit, and poor infrastructure that collectively limit production potential. The study concludes that pig farmers in Ika South LGA possess valuable human capital through education and experience that remains underutilized due to multiple constraining factors. Current adaptation strategies, while innovative, remain limited by resource constraints preventing adoption of more sophisticated technologies. Enhancement www.extensionjournal.com requires comprehensive interventions addressing financial access, technical support, input availability, market development, and institutional strengthening simultaneously rather than fragmented single-issue approaches.
