“…Location of piggeries within 1-km radius of pig slaughter slab was found to be statistically significant and identified as a risk factor. This may be as a result of pig farmers presenting sick and unthrifty pigs for slaughter at abattoirs first without determining the cause of sickness, to which some may be ASF (Randriamparany et al 2005; Fasina et al 2010) thus contributing to ASF spread in nearby piggeries (Costard et al 2009). Since ASF virus is present in tissues and body fluids of slaughtered sick pigs, massive environmental contamination, and possible nearby piggery infection may result.…”

The present study describes assessment of sanitary measures in piggeries of Benue State, Nigeria, to identify the risk factors of African swine fever. Questionnaires were distributed to 74 respondents consisting of piggery owners and attendants in different piggeries across 12 local government areas (LGAs) to collect data for this study. Sanitary measures in piggeries were observed to be generally very poor, though respondents admitted being aware of ASF. Piggeries located within 1-km radius of a slaughter slab (OR = 9.2, 95% CI 3.0–28.8; p < 0.0001) and piggeries near refuse dump sites (OR = 3.0, 95% CI 1.0–9.5; p < 0.05) showed higher chances of African swine fever virus (ASFV) infection, while piggeries where farm workers wear their work clothes outside of the piggery premises (OR = 0.2, 95% CI 0.1–0.7; p < 0.01) indicate less chances of infection but had a significantly associated p value thus were identified as potential risk factors. The study concluded that pigs in Benue State are still at risk of an ASF outbreak. Proper sanitary and hygienic practices are advocated and emphasized in piggeries, while routine surveillance for African swine fever virus antibodies in pigs in Benue State is strongly recommended to provide a reliable reference database to plan for the prevention of any devastating ASF outbreak.

“…In spite of the maximum herd size in Madagascar greater than the maximum size in Cameroon, the median size in Madagascar varying from 3 to 7 suggests that the herd size and the production systems in both countries are the same. This may be partly due to the common disease challenges faced by pig industry in both countries, especially the regular outbreaks of contagious diseases, such as ASF [ 2 , 19 – 21 ]. In fact, the high mortality rate of these diseases (close to 100% for ASF) in affected farms causes farm owners either to remain only with the few survivors, to restock the farms with few animals, or to take less risk in investing for a larger farm.…”

Biosecurity plays an irreplaceable role in preventing diseases and increasing productivity on farm. The main objective of this study was to characterize pig farming and investigate factors influencing biosecurity on pig farms in the western highlands of Cameroon. Data were collected from May to July 2017 using a questionnaire and observations. A technical scoring system was developed from the biosecurity measures. The results revealed that most farmers are males (76.29%), on average 47.82 ± 10.34 years old, with secondary school level (53.61%). The most common husbandry system is extensive (73.22%). Over a total score of 93, measures with higher scores (>80) included “employees do not rear pigs at home,” “animals of different age not in the same room,” “unsold animals from market quarantined prior to reintroduction into the herd,” “production materials not exchanged among farms,” “piggeries clean every day,” “disinfectants used,” “pigs vaccinated,” and “vaccination calendar respected.” Those with the lowest score (<6) were “sanitary lock present,” “use of herd specific clean coveralls and boots on farm,” and “entry restriction sign post present.” The biosecurity level was associated with production system, with the score 6.57 and 3.66 points lower for extensive and semi-intensive farms, respectively, than for intensive system. Farmer's age, gender, education level, and herd size did not affect the level of biosecurity. The results can be used to improve the general biosecurity status in pig herds in the country which in turn will lead, as observed elsewhere, to improved technical performance and economic gain.

“…The pig production sector suffered severe losses following the introduction of African swine fever (ASF) in the late 1990s ( Rousset et al, 2001 ). Currently, its re-establishment is adversely affected by regular outbreaks of contagious diseases, such as ASF, classical swine fever (CSF) and Teschen disease ( Serres and Ramisse, 1969; Randriamparany et al, 2005 ).…”

A cross-sectional study was carried out in 2005 and 2006 in three geographical areas of Madagascar to investigate and differentiate swine farm management and biosecurity practices in smallholder farming communities. Questionnaire data from a total of 709 pig farms were analysed using multiple factor analysis (MFA) and hierarchical cluster analysis (HCA). Variables describing management and biosecurity practices were organised into five groups: structure of the farm, animal-contacts, person- and vehicle-contacts, feeding, and sanitary aspects. In general, few biosecurity measures were implemented in the pig farms included in the study. Regional differences in management and biosecurity practices emerged from the MFA and were mainly due to, in order of decreasing importance: structure of the farm, sanitary aspects, feeding and animal-contacts and, to a lesser extent, person- and vehicle-contacts. HCA resulted in the differentiation of four distinct types of farms in each of two study areas, Arivonimamo and Marovoay, while no grouping could be identified amongst farms in Ambatondrazaka area. The characterisation of the different types of smallholder pig farms will allow adapting recommendations on husbandry practices and control measures in pig farms of these regions of Madagascar. The development of tailored recommendations is essential for Malagasy smallholders who have limited resources and need to make evidence-based management changes to reduce the risk of contagious diseases in their herds.
