“…ASF is endemic in Southwest Nigeria and the results of the present study is far lower than 28% reported by Awosanya et al (2015) with higher prevalence during the dry season compared to rainy season. On the contrary, a total seroprevalence of 2.8% was reported in Benue which is further delineated into two categories, prevalences of 7 (1.7%) and 6 (13.6%) were observed in piggeries and in Makurdi slaughter slab, respectively (Asambe et al, 2018). It seems there is less prevalence at piggery pen than slaughter slabs.…”

“…The detection of antibody against ASF was carried out by indirect Enzyme-linked immunosorbent assays (ELISA) as recommended by the manufacturer (IDvet,310, rue Louis Pasteur-Grabels-FRANCE). ELISA was carried out in a 96-well plate as described in previous study (Asambe, Sackey, & Tekdek, 2018). Briefly, 100 µl of dilution Buffer 14 to each well, which was followed by addition of 10 µl of the negative control buffer (supplied with the kit) to wells A1, B1 and A2, and B2.…”

African swine fever (ASF) is the most important disease limiting small holder pig production in Nigeria, causing mortality as high as 100% resulting in total loss of investment. African swine fever is of public health concern because it is a recurring disease in many countries including Nigeria. This study was undertaken to investigate the presence of antibody (IgG) against African Swine Fever Virus (ASFV) among pig population in Lere and Zaria local government areas (LGAs) of Kaduna State of Nigeria. A total of 45 blood samples were collected from different suspected pigs from Lere and Zaria local government areas (LGAs). Eighteen serum samples were obtained from eighteen different suspected pigs from the pig population in Lere LGA while twenty seven serum samples were also obtained from twenty seven different suspected pigs at Zaria LGA. The samples were tested by conventiolan indirect Enzyme-linked immunosorbent assays (ELISA). The results showed 2 samples representing 11.11% of the total samples collected from Lere LGA were positive for ASF antibody. On the contrary, none of the 27 samples obtained from Zaria LGA was positive. Therefore, the overall seroprevalence was 4.4%. Pigs with demonstrable antibody should be considered as carriers of the virus because it is uncertain if true recovery ever occurred in them. Control measures such as use of biosecurity, routine test and slaughter of animals that tested positive for ASF antibody were recommended. Further studies are also suggested to involve larger sample size and better diagnostic technique such as polymerase chain reaction, having observed that ELISA –detected ASFV antibodies do not transfer into clinical ASF.

“…This study further reveal that the farmers are small scale farmers and as such generally have small flock size and hence family labour may be adequate. The low herd size may also be partly due to the common disease challenges faced by the pig industry in Benue State, especially the regular outbreaks of contagious diseases, such as ASF (Asambe et al, 2017). 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 (Kouam and Moussala, 2018).…”

“…Combining farm-mixing of feeds and kitchen wastes may be more economical than using commercial feeds alone. However, kitchen wastes are not properly heated before feeding it to animals, the risk of transmitting diseases such as African Swine Fever (ASF) among other diseases is high (Asambe et al, 2017). Purchasing replacement stock for breeding within the same locality predisposes to inbreeding and subsequently low production, reproduction and poor health (Kirima et al, 2017).…”

The role of biosecurity at farm level is to reduce the risk of introduction of diseases in pig farms and prevent the disease transmission between animals on farms. It is an important management practice that impacts the profitability of pig production ventures. A survey was conducted to assess the biosecurity practices in 50 farms in Makurdi, Benue State, Nigeria, using a structured questionnaire and assessments through direct observations. Descriptive statistics such as frequencies, percentages and tables were used to analyse and present data generated. The results revealed that majority of the farms were semi-intensive (54%), small scale producers keeping between 1 and 50 pigs formed 96% of surveyed farms and essentially raising indigenous and crossbreed (72%). Only 12% of the farms were fenced and had gates closed to control unwanted visitors and stray animals. Most of the farms (76%) had no footbaths indicating that the risk of disease introduction was high in such farms. The use of protective clothings and foot wears by employees was only observed on 24% of the farms. Isolation of sick animal was practiced by 38% of respondents while 24% of respondents quarantined new animals to the farm. The use of disinfectants to clean the barns was practiced on 18% of the farms. Overall, there was a low level of farm biosecurity in the study area. Extension services to create awareness on the importance of biosecurity would help limit infections and boost pig production and profitability.

The challenge is how to mitigate the risks to reduce or eliminate losses due to ASF and make smallholder pig production more profitable and sustainable.…”

African swine fever is a serious viral disease of domestic pigs and Eurasian wild boars that poses a major threat to pig production. For more than thirty years after its discovery in East Africa it was limited to eastern and southern Africa, where it is believed to have originated. The ability of the causative virus to remain viable for long periods in raw or insufficiently cooked pork products has enabled it, through travel and trade, to spread widely throughout sub-Saharan Africa and to other continents. In the second half of the 20 th century it had caused outbreaks in the majority of African countries where pigs are produced, as well as in a number of European countries, two of the Caribbean islands, and Brazil. By the turn of the century it had been eradicated from all non-African countries except the Italian island of Sardinia. In 2007 African swine fever arrived in the Republic of Georgia, and has subsequently spread insidiously into other Transcaucasian countries, Russia and some of its neighbours. In 2014 it reached the Baltic States and Poland through infected wild boars, and has become established in several wild boar populations from which it is difficult to eradicate. Most recently, in 2018 the first outbreaks were reported in China, home to half of the world's pig population, where it spread with unprecedented rapidity throughout China and to several other countries in the region, including the island nations of Philippines, Indonesia, Timor-Leste and Papua New Guinea. These events have posed new challenges for control, including some that parallel the situation in Africa, where poor people rely on pigs produced at subsistence level to provide for their needs and where pigs may also be socially and culturally important. The central role that humans play in the maintenance and spread of African swine fever has again been emphasised. This review describes the current status of African swine fever globally and the trends and challenges for management that face veterinarians and pig industries at all levels worldwide.
