Limpopo is a very important area for pig production in terms of animal populations and contributions to transboundary animal disease spread. Emerging small-scale pig farmers (ESSPF) are being encouraged to establish operations and spread in South Africa; however, for these farmers to perform optimally, they need to understand the basics of animal agriculture and contribute to enhancing biosecurity and efficient production systems. In the present study, the limitations to efficient production amongst ESSPF were evaluated and some improvements were suggested. It was found that the ESSPF are dominated by males and include a large percentage of older persons. A total of 26.54% of these farmers have post-matriculation qualifications. Undefined and indigenous breeds still dominate their animal genetics. The animal health technicians are the preferred channels by which farmers report diseases to the authorities (52.47%) and only one out of five (20.37%) will preferably report a disease situation direct to a veterinarian. These farmers do not vaccinate their stock, and knowledge of biosecurity is poor. Antimicrobials, especially tetracyclines, are abused. Animals that are slaughtered within the community or sold at local sale points, pension pay stations and auction markets are likely candidates for disease spread. It is recommended that the younger generations are retained and incentivised in animal agriculture. Improved training on management, health, biosecurity and better market access must be provided for the ESSPF, whilst efforts should made to consolidate these farmers into small cooperatives. The current government agricultural support system will need to be reworked to benefit the resource-poor farmers. Collaborative efforts in disease reporting and management among veterinarians, animal health technicians and extension officers will become necessary. Finally, the creation of a progressive quality grading system for ESSPF should be planned by the industry and this should be attached to a reward system that will encourage these farmers to target good farming practice.


Pigs are of high economic importance, especially among the poor. They contribute to human nutrition, food security, poverty alleviation, enhanced livelihood and creation of employment for the rural community (Antwi & Seahlodi 2011; Dietze 2011; Mergenthaler, Weinberger & Qaim 2009). In addition, they provide a less-expensive source of animal protein for urban diets compared with cattle, sheep and goats (Ironkwe & Amefule 2008). Whilst pig farming, as part of animal agriculture, is central to the development of rural farmers, the real contribution of emerging small-scale pig farmers (ESSPF) to the rural economy is not well assessed and somewhat doubtful. These economic contributions by ESSPF are constrained by management, health, housing, feeding and marketing constraints (Antwi & Seahlodi 2011; Chikazunga et al. 2007).

In South Africa, it is suggested that there were approximately 125 000 production sows in 2010/2011, with approximately 100 000 sows being held commercially and the remaining 25 000 being kept by small-scale farmers. The South African pork industry contributes around 2.15% to the primary agricultural sector, and whilst 2 616 000 pigs were slaughtered in 2011, the total pork production was put at 203 375 tonnes in cold dressed mass (Food and Agriculture Organization Corporate Statistical Database [FAOSTAT] 2014).

Limpopo is a major pig-producing province in South Africa and, in 2011, contributed approximately 24.00% of the total recorded pig production (Department of Agriculture, Forestry and Fisheries [DAFF] 2012). Only about 11 700 of all the sows in the province are registered as commercial sows and there is a widespread distribution of non-registered and disorganised medium-scale and small-scale pig farms. In view of its location and poorly controlled boundaries with other countries, previous studies have indicated that Limpopo has played a key role in some transboundary animal disease disseminations and is responsible almost exclusively for new introductions of African swine fever into South Africa (Boshoff et al. 2007). Since all the index cases, to date, of outbreaks of African swine fever in South Africa have originated from Limpopo and the majority of these outbreaks were linked with small-scale pig farms, it is critical to understand the management and production systems of this category of farms in order to effectively carry out proactive disease prevention and management. The present study was conducted in order to collect basic management and health parameters from ESSPF in Limpopo, so that their production efficiency and contributions in terms of biosecurity and health could be evaluated.

Materials and methods

Study area and data collection
Five districts in Limpopo province were studied, namely: Sekhukhune, Capricorn, Waterberg, Vhembe and Mopani (Figure 1). These districts have partially documented records (n = 85) of ESSPF; Limpopo’s Department of Agriculture is in the process of fully documenting the records of these pig farmers. This will enable targeted interventions in terms of infrastructure development, veterinary extension services, and production and marketing inputs to be carefully planned to assist these farmers. A purposive sampling method was used to select ESSPF (n = 185) from the study sites, including the 85 small-scale pig farmers enlisted on Limpopo’s Department of Agriculture list and an additional 100 farms that fall within this category but were not listed. The expansion of the list beyond the department list became necessary because the preliminary data from the field suggested that there were many unlisted ESSPF in the province (Steyn et al. 1994). The inclusion criterion for the present study was pig farms with ≤ 50 sows, located within the five districts of Limpopo, that have been active in pig production for at least one year. A participatory research model approach was used (Raman, Sanghi & Chambers 1989; Thrusfield 1995).

Data collection and management
Based on available literature, expert opinions and primary objectives of the present study, a semi-structured questionnaire (see Appendix 1 for content) was designed at the Department of Production Animal Studies, University of Pretoria. This was pilot tested amongst veterinary students (n = 12) and a few extension veterinarians (n = 2). The questionnaire was later reviewed and validated during organised consultative forums by selected pig veterinarians in the field, the Research Committees of Limpopo Department of Agriculture and the Faculty of Veterinary Science, University of Pretoria, as well as state veterinarians and animal health technicians of the Limpopo Department of Agriculture. The instrument was used to collect data from the selected participants using a participatory method, as described by Thrusfield (1995). A total of 185 questionnaires were collected from the field, but 20 were filtered out due to missing values and inconsistent data. Another respondent was removed because he had increased his herd size to a 150 sow unit. A total of 164 respondents (88.65%) were included in the analysis. The data from completed questionnaires were coded, captured and filtered using a Microsoft Excel® (Microsoft, USA) spreadsheet, and descriptive statistics were performed. The analyses performed included: proportional percentages; measures of central tendencies; percentiles and graphs of farm characteristics; production parameters; management and health parameters; and operational efficiencies using STATA v9.0 (Stata Corporation, Lakeway Drive, College Station, Texas, USA). Efficiency indices for piglets weaned per sow and for average days to oestrus were calculated by dividing the category mean by mean total number of sows for the category. Correlation coefficients were calculated for farm parameters that were thought to influence one another in the analysed data.


Male farmers represented the majority of the participating respondents (76.83%), which is a reflection of the population structure amongst the ESSPF (Table 1a). Similarly, the farmers who were ≥ 46 years old were 78.53% of the total respondents; 5.52% were ≤ 35 years and 15.95% were 36–45 years old. In addition, a total of 77.78% of the respondents were married (Table 1a). The majority of the farmers interviewed (63.80%) were engaged full time in their pig farming activities, whilst only 26.90% were involved part time.

TABLE 1a: Characteristics of emerging small-scale pig farmers, Limpopo, South Africa.

TABLE 1b: Characteristics of emerging and small-scale pig farms, Limpopo, South Africa.

It was noted that 26.54% of the total respondents had post-matriculation qualifications. Although the definition of breeds was based on phenotypic characteristics of the pigs observed on the farms, 61.18% of the breeds used were indigenous or not well described, 28.29% were Large White, 10.53% were Landrace and 7.24% were Duroc breeds (Table 1a). A total of 2.47% ESSPF farmers had previously benefited from the Comprehensive Agricultural Support Programme (CASP) of the Limpopo Department of Agriculture. The average number of sows per farm was 7.4 and the average number of days for a sow to return to oestrus was 42.9 days after weaning the litter, whilst the number of piglets weaned per sow per year was 4.85 pigs (Table 1b). At this rate there would need to be some 50 000 sows (unregistered) in Limpopo to make up half of the 24.00% of slaughter pigs that are not accounted for by the 11 700 registered sows mentioned in the introduction above. It is questionable whether this really is the case.

The majority of the respondents (92.36%) did not provide a heat source for their piglets, especially in the cold winter, and this greatly impacted on increased levels of mortalities. In addition, 44.00% lost piglets primarily due to overlay and hypothermia, whilst 62.67% claimed that piglets were lost principally to multiple causes (Table 2). The interviewed farmers complained about skin conditions in their herds and approximately 46.84% of the respondents identified skin diseases (primarily mange) as being the most important disease complex on their farms (Table 2). Other disease complexes that were rated lower by the farmers included: reproductive (12.66%), enteric (8.86%), respiratory (6.33%), musculoskeletal (5.05%) and mixed infections (39.87%) (Table 2).

TABLE 2: Management and health parameters of emerging and small-scale pig farms, Limpopo, South Africa.

A total of 52.47% of the ESSPF preferred to report to and use the service of animal health technicians. State veterinarians were the first point of contact for one out of five farmers (20.37%), and 17.28% preferred to contact the extension officers first. Knowledge and implementation of biosecurity was poor amongst the surveyed farmers, as only 8.07% washed their hands before or after farming activities, and only 1.24% utilised footbaths in their farms. Although 65.84% indicated that they had built fences, it was noted that these fences were not purpose built for biosecurity and were only extensions of the human accommodations.

Most importantly, 98 (77.00%) of the farmers did not vaccinate their pigs against major pig diseases, including parvovirus infection, leptospirosis and erysipelas. Terramycin was the most abused drug used by 30.38% of the responding ESSPF, as no diagnosis was reached before treatment was implemented in most cases.


The majority of the respondents (82.61%) preferred or were obliged to sell their pigs at local points and within communities, 9.32% would sell at the auctions and 14.09% at formal abattoirs or supermarkets. A total of 40.67% of the farmers transported their pigs to the slaughter facilities and only 1.33% of these farmers transported live pigs from different sources in the same vehicle (Table 3). These transportations vary widely between < 50 km and 400 km, depending on the distance of the major abattoir or auction points (Figure 2).

FIGURE 2: Distance analyses of movement from farms to major slaughter and marketing points, (a) Belfast auction, (b) Phalaborwa abattoir, (c) Bronkhorstspruit abattoir and (d) Thabazimbi abattoir.

TABLE 3: Market-related characteristics of emerging and small-scale pig farmers, Limpopo, South Africa.

An evaluation of the price that the farmers received per pig sold revealed that there is a great lack of coordination in pricing and no template exists to standardise sales. For example, a 32-week-old pig (50 kg – 70 kg) sells for approximately ZAR 500 compared to ZAR 1200 for a 20-week-old pig (≈ 70 kg) in a formal market. It should, however, be emphasised that these pigs often have a high bone-to-meat ratio when compared with those originating from a commercial operation.

Although a good proportion (41.25%) of the farmers claimed to use concentrates in feeding their pigs, evidence based on the drawn-up checklist contradicted this assertion. It appeared that most of the farmers used kitchen remnants and mixed portions, and only supplemented with vegetables and concentrate feeds (Figure 3). A total of 43.83% used boreholes as sources of water for their piggery but a proportion (32.10%) used village streams and other water sources like rivers (9.26%) and municipal water (6.78%) (Figure 3).

FIGURE 3: Main source of feed and water for the pigs.

The majority of the farmers (81.76%) had less than 10 sows (Figure 4, Table 4), and this category of farmers appeared to have the best efficiency index compared to other categories in terms of number of piglets weaned per sow per year (n = 5.19). It appeared that the higher the number of sows per ESSPF, the lower the efficiency of weaning per individual sow on the farm (Table 4).

FIGURE 4: Evaluation of farm sow population against average number of piglets weaned per year.

TABLE 4: Efficiency index of piglets weaned per sow.

The average number of days after weaning for sows to return to oestrus in the ESSP farms was 42.9 days (Table 5), but there was significant difference amongst the different categories (1–10, 11–20, 21–30, 31–40, 41–50) (p < 0.0001). Sows of those farmers with between 1–10 sows took approximately 49.9 days to return to oestrus, whilst those with between 21 and 30 sows returned to oestrus within 16 days (Table 5, Figure 5); however, some farms with less than 10 sows took up to 210 days for their sows to return to oestrus (Figure 5).

Overall, the level of education was negatively correlated with all of the farm parameters assessed, except the piglets per sow per year, where it had a very poor correlation. The total piglets weaned was positively correlated with the total number of piglets born per sow per year (39.86%) and the number of sows on the farm was positively correlated with the total piglets weaned (30.97%) (Table 6).

The present study’s findings and analyses revealed some deficiencies. It is a difficult task to collect critical production parameters where no records exist to validate the collected information, and the farmers’ perceptions and recall are the only forms of validation. In the present study, efforts were made to use check questions and interviewees’ observational analyses to validate some of the data collected from the farmers. Despite this challenge, the present study has revealed that most of the ESSPF in Limpopo province are males (77.00%), a fact that has raised questions about the issue of women in agriculture and economic empowerment in this sector. It appears that the pig industry has a large imbalance in terms of ownership and gender, and there may be a need to transform the industry and provide more opportunities with a critical focus on women from rural areas. It should be understood, however, that pig farming is labour-intensive in terms of input; few women may be willing to get involved in such activities. Whilst gender equity is one of the major standpoints of the land reform policies, to date, female ownership of land and other means of agricultural production, especially in the rural areas, is still viewed with some degree of abhorrence in the region (Anon 2014; Cross & Hornby 2002; Kalabamu 2006).

The majority of the farmers were older than 45 years of age, which is an indication that the younger generation prefer not to get involved in agriculture but would rather migrate to urban areas in search of salaried jobs (Brooks et al. 2013). This observation may also be an indication of late entry into animal agriculture. A similar trend has been observed in other studies (Oladele, Kolawole & Antwi 2013; Schembri et al. 2013). Currently, it is widely believed that only the poor become involved in rural farming and that it is not a financially rewarding activity. It is recommended that policies be implimented that encourage younger individuals to be retained in the rural areas at all levels in order to reduce gross emigration to the city, whilst boosting agricultural productivity in the rural areas.

Because pig farming in the rural areas is labour intensive, larger families and married people are at an advantage, as two or more people are involved. The outcome of the present study’s analysis indicates that 78.00% of all respondents were married. The majority of the farmers were also educated up to the end of high school (58.64%). Previous workers have confirmed that the level of education has a positive relationship on market access (Lubungu, Chapoto & Tembo 2012). Since farmers with post-secondary education constituted just over a quarter of the total respondents, it is expected that these educated farmers positively influence the market and open access for the less educated ones. It is important to emphasise that the majority of the respondents still kept indigenous and crossbred pigs; these results are comparable with other data from India (70.00%) (Nath et al. 2013). These indigenous and undefined pigs have been known to under-perform compared with the exotic breeds in terms of litter size, litter weight, birth weight, weaning weight and average daily weight gain, and they often have poor access to veterinary services (Halimani et al. 2010). Extension services must be targeted towards encouraging farmers to adopt the improved breeds of pigs in rural farm operations.

Although the Department of Agriculture, Forestry and Fisheries has made certain provisions available for funding of animal infrastructure in terms of the CASP, only 2.47% of the respondents have benefited. It will be necessary for government departments to fine-tune agricultural policies and remove unnecessary bottlenecks that impede the development of ESSPF so that planned programmes and policies can reach the targeted beneficiaries. In the current programme, the farmers are supported in terms of provision of 10 sows or a housing unit for 10–50 sows. A realistic economic model has indicated that farmers will need between 150 and 250 sows to be commercially viable. Whilst the government may not be able to provide this level of support for all the ESSPF, the options of forming them into smaller cooperatives to benefit from economies of scale and become more competitive in terms of input supplies and marketing should be explored (Mashala 2012). In addition, financial institutions should be encouraged to provide low-interest agricultural financing to farmers with viable projects.

With regard to productivity, analysis indicated that the ESSPF are poorly productive, compared with the commercial operations. They weaned an average of 4.85 piglets per sow per year, which is 19.00% of the standard for the South African pig industry (26 piglets per sow per year) and it took much longer for the sows to return to oestrus (42.9 days compared with 4–6 days) (Fasina et al. 2012). The statistics generated in the present study are incompatible with economically feasible and viable pig production; there will be a need for a major shift if the ESSP farms are to be commercially viable and sustainable in South Africa. At the same time as consideration is given to these statistics, they should also be carefully examined, since large variations exist between the farmers’ operational efficiencies in each category.

Hypothermia is a major source of neonatal and piglet mortalities; it also predisposes piglets to other causes of mortalities including diseases, crushing and starvation (Kammersgaard, Pedersen & Jørgensen 2011; Pedersen et al. 2012). Hypothermia will significantly reduce the ability of piglets to access the sow and get colostrum within the first 6 h – 12 h after birth to meet their nutritional requirements, to benefit from maternal immunity and protect against diseases. Regular supervision in the farrowing house would help to reduce the levels of mortalities in terms of prevention of hypothermia, regular feeding, reducing illnesses and maintaining sow’s udder health (Shankar, Madhusudhan & Harish 2009); this was lacking in the surveyed farms. The great majority of the respondents (92.36%) did not provide any heat source and the high level of pre-weaning mortality observed in the farms of ESSPF in Limpopo can be attributed to this situation. Pedersen et al. (2012) confirmed that mortality associated with hypothermia can be seven times more severe in piglets subjected to suboptimal environmental and floor temperatures in the first week of birth (Kammersgaard et al. 2011). Building of simple, but cosy, creeps using local materials can be a cheap but good alternative to using electricity to heat up creep areas. This should potentially reduce hypothermia and encourage piglets to suckle more, with consequent reduction in piglet pre-weaning mortality, and boost performance.

Pigs are exposed to a variety of predisposing factors and pathogens causing diseases. Primary diseases and conditions of concern in the industry include production-limiting diseases, respiratory complexes and lameness-associated problems, amongst others. In the present study’s analyses, for ease of recognition by the ESSPF, disease complexes were grouped as syndromes. The disease conditions were grouped as respiratory, enteric, skin or integumentary, musculoskeletal and reproductive syndromes. A total of 46.84% of the respondents indicated that skin conditions were a major challenge on their farms. Further enquiries from respondents confirmed that the conditions in pigs were observed as scratching, with discoloured or thickened skin, scabs and hair loss, among others, which are indications of sarcoptic mange (Arends, Stanislaw & Gerdon 1990). Mange significantly depresses growth rate and feed efficiency, and it is expected that a considerable loss in days-to-market prevails amongst the pigs from these farms for that reason. Many of the farmers sell their pigs at an average of 8 months, a loss of about 90 days compared to the commercial operations. A total of 22.15% of the respondents mentioned ivermectin as a frequently used medicine on the farms. It is particularly concerning that terramycin is used routinely by about 30.00% of the farmers, without proper diagnosis and consideration of its consequences. It is recommended that a community-specific farm-health plan be constructed to target this group, using state veterinarians and animal health technicians. Such health plans must include messages on the importance of vaccination, antibiotic abuse and biosecurity, areas, where serious deficiencies were observed amongst the respondents (Food and Agriculture Organization [FAO] 2010; Fasina et al. 2012). Vaccination against very important production-limiting diseases of pigs in South Africa (parvovirus, leptospirosis and erysepelas, as well as Escherichia coli) must be included in such protocols. Similarly, it would be beneficial to use vaccines on a cost-sharing basis between farmers.

Since the farmers use the services of animal health technicians, extension officers and veterinarians, there is a need for coordination among these professionals to maximise the impact of state veterinary extension services and block loopholes that may exist with individual efforts. Data, which are comparable to the present study’s statistics, about increased reliance on technicians rather than the veterinarians by ESSPF, has been reported elsewhere (Alawneh et al. 2014). It should be emphasised that disease complexes among the ESSP farms pose major risks to the commercial operations. Therefore the inclusion of private veterinarians and large commercial farms in sponsoring veterinary extension services amongst these individuals whilst serving the role of mentors and patrons must be critically evaluated. The extension messages must also target how market access can be created for these farmers and a suitable grading system that will encourage them to maximise productivity and move towards good farming practices. The role of veterinary extension and the use of multiple professionals to meet the challenges of animal health services have been emphasised previously (Hernández-Jover et al. 2008; Mockshell, Ilukor & Birner 2014). The determinants of cooperation and referrals between paraprofessionals and veterinarians have been previously identified to include mobile phone ownership, training, cumulative annual assessment, and membership of paraprofessional bodies and association (Ilukor, Nielsen & Birner 2014). It is necessary to facilitate inter-professional relationships amongst animal health service providers in rural South Africa by provision of the identified facilities.

Nutrition and feeding are very important components of animal production and health; in the present study, it was concluded that the ESSPF are more likely to swill-feed the pigs, with potential consequences of spreading diseases, including exotic pig diseases like classical swine fever, foot-and-mouth disease and porcine respiratory and reproductive syndrome. Similarly, since the swill is not evaluated for its nutritional qualities, it becomes difficult to assess whether this feed meets the nutritional requirement of the different classes of pigs on the farms. It is probable that the weaning and growing pigs are underfed and this is responsible for their taking longer to reach appropriate market weights (Manchidi 2009; Viljoen 1993).

Water is a critical resource in any pig production unit, as it is required for cleaning the pens, drinking purposes and cooling the pigs. In many of the farm units included in the present study, pigs get water only twice a day, whilst certain piggeries only supply water every other day. Limited access to water has negative effects on pigs, as it retards their growth potential and affects many other biochemical processes, resulting in conditions such as salt toxicity (Manchidi 2009). Based on estimation, the greater the distance between the household or production site and water source, the higher the probability of not providing water regularly. Since about 45.06% of the farmers only depended on village streams or other distant sources for water, pigs reared under these conditions are likely to suffer degrees of water deprivation. However if a farmer wants to proceed with a regular supply of feed and water, despite the distance between the farm and sources of supplies, a higher capital cost will be incurred and realistic profitable operation will become more difficult (Mabuza & Ngubane 2010).

Finally, the South African pig retail industry is broadly classified into a dual market structure: the high-value markets (processors and supermarkets) for commercial pig farmers and the low-value markets (local auctions, pension pay points for the ESSPF). Whilst the high-value markets pay premium prices for quality products, the emerging small-scale pig farmers get paid below the market values for their pigs (Antwi & Seahlodi 2011). The present study’s findings confirmed this assertion, since no coordinated pricing and standardised sale template exists for this category of farmers. The use of extension services to improve sectoral marketing and possible formation into cooperatives is critical.
