En Afrique et particulièrement au Bénin, l’élevage du porc constitue une activité génératrice de revenu. Toutefois, les acteurs de ce secteur sont confrontés à de nombreuses difficultés dont le parasitisme qui entraîne une baisse de production et de productivité. Le présent travail a pour but de faire une revue de littérature sur les parasites qui affectent l’élevage des porcs en Afrique et particulièrement au Bénin. De l’analyse des données collectées, il ressort que trois types d’élevage sont pratiqués au Bénin : l’élevage traditionnel, prédominant et pratiqué à 65%, l’élevage semi-intensif ou semi moderne à 32% et enfin l’élevage intensif ou moderne à 3%. L’amélioration des conditions d’élevage et particulièrement l’alimentation du porc indigène d’Afrique est favorable à l’expression de son potentiel zootechnique. Malgré l’optimalisation des rations, les performances zootechniques du porc local restent encore faibles par rapport à celles des races améliorées. Très peu d’étude sont abordé la prévalence des parasites internes du porc au plan national, mais parmi les parasites rapportés, on a noté : Ascaris suum, Strongyloides ransomi, Trichuris suis, le genre Hyostrongylus et d'autres parasites internes du porc. Il s’impose de mener une étude sur les parasites du porc au Bénin afin de déterminer la prévalence des différents parasites et le danger que ces derniers représentent pour le développement de cette filière.   English title: Zootechnical importance and internal parasites of local pigs (Sus crofa domesticus) raised in Benin: bibliographic synthesis In Africa, and particularly in Benin, pig farming is an income-generating activity. However, the actors of this sector are confronted with many difficulties, including parasitism which leads to a decrease in production and productivity. The aim of this study is to review the literature on parasites affecting pig farming in Africa, articularly in Benin. From the analysis of the data collected, it appears that three types of livestock production are practised in Benin: traditional livestock production, which is predominant and practised at 65%, semi-intensive or semi-modern livestock production at 32% and finally intensive or modern livestock production at 3%. The improvement of breeding conditions and particularly the feeding of the indigenous African pig is favorable to the expression of its zootechnical potential. Despite the optimization of rations, the zootechnical performance of local pigs is still low compared to that of improved breeds. Very few studies have addressed the prevalence of internal parasites of pigs at the national level, but among the parasites reported were: Ascaris suum, Strongyloides ransomi, Trichuris suis, the genus Hyostrongylus and other internal parasites of pigs. It is necessary to conduct a study on pig parasites in Benin in order to determine the prevalence of the different parasites and the danger that they represent for the development of this sector.

The article describes a laboratory study of nematocidal properties of flavourings with antibacterial effect against Ascaris suum (Goeze, 1782) and Trichuris suis Schrank, 1788. In the experiments, eight concentrations of food additives with antibacterial properties were used: cinnamaldehyde, benzoic acid, formic acid, linalool, citral, β-ionone. Minimum LC50 value for eggs of A. suum was observed while using cinnamaldehyde and benzoic acid – 1.62 ± 0.37% and 1.69 ± 0.14%, and for eggs of T. suis – 0.57 ± 0.03% and 1.80 ± 0.11% respectively. The lowest influence on the development of eggs of nematodes of pigs’ A. suum and T. suis was exerted by formic acid, linalool, citral and β-ionone. In eggs of A. suum and T. suis, larvae formed in 21 and 50 days even during exposure to 3% emulsions of these substances. The strongest negative impact on the eggs of parasitic nematodes was displayed by cinnamaldehyde flavouring. Further study on nematocidal properties of flavourings, as well as their mixtures, would contribute to the development of preparations which would have a strong effect on eggs and larvae of nematodes of animals and humans.

A database was built with the results of the physicochemical analysis of 23,435 samples of wastewater discharges obtained from the operational reports presented and the cross-checks carried out by the Ministry of Health to the operating entities, in accordance with the provisions of Decree 30661-MINAE-S, for the period 2016–2020. Using Bayesian networks, the probabilities of compliance with current regulations were estimated by preparing an acyclic directed graph for three alternative scenarios. At the national level, the BOD and the COD are the variables that record the lowest values, showing important differences between the results obtained for the central region of the country with respect to the other regions. Another determining variable turned out to be the type of final disposal, wherein the reuse of wastewater presents important compliance deficiencies for all regions except for Chorotega. In the case of BOD, COD and TSS, the lowest probabilities are recorded for ISIC codes 3821 (treatment of non-hazardous waste), 1040 (manufacture of animal and vegetable fats) and 145 (pig farming). Additionally, the integrated environmental risk was calculated as a product of the discharges, obtaining that for the evaluated parameters, the BOD and COD represent the highest risk values given their probability of occurrence rate, as well as the magnitude of the environmental impact. The Pacifico Central and Brunca regions recorded the highest integrated environmental risk value for BOD, COD and TSS compared to the other areas of the country. Based on the results obtained, proposals for improvement were generated for the control of wastewater discharges carried out by the environmental authorities in search of achieving a better comprehensive management of the water resource.

Abstract The goal of this study was to assess the effect of farm size (FS) and farrowing order (FO) on the occurrence of endoparasites eggs in commercial sows housed in maternity and gestation areas during the period from May to July 2014. Forty-three piglet production units were classified by FS: small (100 to 250 sows), medium (251 to 510 sows), large (511 to 1,000 sows) and very large (more than 1,000 sows). Sows were classified by FO: up to two, three to five or more than five parturitions. Faecal samples were processed using the simple flotation technique in a hypersaturated salt solution (30-35% NaCl). The results revealed that the overall prevalence of gastrointestinal endoparasites obtained in this study was 12.47%, in that 4.64% were positive for Ascaris suum, 0.56% for Trichuris suis and 8.27% for coccidia oocysts. The prevalence of endoparasites obtained for small and medium size farm, and for large and very large farm was 34.58% and 15.52%, respectively. In conclusion, the study shows that more than half of the farms were positive for A. suum and coccidia oocysts, but mainly for younger females. In general, sows with up to two parturitions and small farms showed a higher endoparasites percentage.

Abstract Increasing food production can be done through increasing productivity and increasing business scale, both of them need an additional cost. Meanwhile, capital for small-scale farmers is relatively limited, so financial support is needed. At present, the Government financing support in the form of loans program is the People’s Business Credit (KUR). The objective of the study is to analyze the role of KUR in beef cattle business and the effect on increasing livestock production. The research was conducted in 2020 in Central Lampung District with a survey method of 60 farmer respondents. The study revealed that at the national level, the participation rate of beef cattle farmers in the use of KUR was only 2.71%, and in Lampung Province, it reached 7.72%. Beef cattle farmers in the study locations used KUR funds for on-farm farming. Most of the farmers (84.4%) used the funds to purchase brood stock. The KUR program has an impact on increasing the productivity of cattle for fattening 0.2 kg live weight/head/day, increasing the scale of cattle breeding, and fattening two cows and eight cows respectively per farmer. The impact of KUR on enhancing production due to increased productivity and business scale is significantly determined by the level of farmer participation in the use of KUR. It is needed to increase farmer participation in the use of KUR and the use of KUR funds to adopt recommended technology. So that, KUR has impact on increasing livestock production.

Among the parasites that affect pigs, Ascaris suum stands out for causing the greatest losses to livestock production systems. This parasite can be monitored during the slaughter of animals through the identification of “milk spots” or white patches on the liver caused by its larval migration. However, infection in the herd is usually subclinical, which is why the presence of this parasite in industrial pig production has been overlooked. The aim of the study was therefore to evaluate the occurrence of milk spots on the liver of animals slaughtered in the micro-region of Ponte Nova in the Zona da Mata - Minas Gerais, Brazil, and to associate these lesions with the time of year, herd size and source of origin of the animals. An evaluation was made of 1,069 lots, totaling 108,073 animals, based on data extracted from the Federal Inspection Service. The animals were slaughtered during the period of January 2011 to June 2013. Out of the total number of slaughtered animals, 10,535 (9.75%) tested positive for these lesions. Therefore, veterinarians and producers should be warned about the inefficiency of the deworming protocols that are used, and the need to develop and/or review control strategies for this parasite in production systems.

Study Development

Pig faeces were deposited on experimental plots in the spring, summer, autumn and winter to study development and survival of Ascaris suum and Trichuris suis eggs under outdoor conditions. Faeces were placed either in short grass or 2 cm below the surface of bare soil, imitating pastures used by nose-ringed, grazing pigs or normally rooting pigs, respectively. The numbers and developmental stages of the eggs were recorded in faeces and soil for up to 50 weeks post-deposition. Embryonation took place only during the summer months and seemingly was independent of the microclimate. The majority of A. suum and T. suis eggs, which are generally considered to be extremely resistant and long-lived, seems to disappear rather fast. The disappearance rate for A. suum eggs was higher than for T. suis eggs, and both egg types disappeared significantly faster in the summer months than in the winter months, and when placed in short grass than when buried in soil (less exposed). We discuss how knowledge on egg development and survival may be used in the planning of pasture strategies for control of helminth infections in outdoor pigs.

The objective of this experiment was to investigate a possible interaction between protein and energy malnutrition (PEM) and intestinal nematode infections. We report on a 3×2 factorial study in which pigs were fed either a low protein energy (LPE), low protein (LP) or a normal protein energy (NPE) diet, and 6 weeks later inoculated with Trichuris suis (4000 infective eggs). Secondarily, in order to obtain a polyparasitic status, pigs were concomitantly inoculated with Ascaris suum (600 infective eggs). The number of T. suis-infected pigs was higher in LP pigs compared with NPE pigs (100 versus 58%; P = 0·037), although the differences in median T. suis worm burdens between groups at necropsy 10 weeks post-infection (p.i.) (LPE: 795; LP: 835; NPE: 48 worms; P = 0·33) were not significant. Interestingly, only T. suis in NPE were highly aggregated (k = 0·44), in contrast to a more uniform distribution among pigs in LPE (k = 1·43) and LP (k = 1·55) i.e. the majority of pigs harboured moderate worm burdens in LPE and LP, while most pigs had few or no worms in NPE. Further, T. suis worms in the LPE and LP groups were decreased in length (mean: LPE: 23·5 mm; LP: 24·3 mm; NPE: 29·4 mm; P = 0·004). The pre-patency period of T. suis was also extended in the LPE and LP groups, as reflected by lower faecal egg output at week 6 (P = 0·048) and/or 7 p.i. (P = 0·007). More A. suum worms were recovered from LP compared with the NPE group (mean: 5·4 versus 0·6; P = 0·040); this was accompanied by a higher faecal egg output in the former (P = 0·004). The low protein diets resulted in lower pig body weight gains, serum albumin, haemoglobin and packed cell volume (PCV) levels as well as diminished peripheral eosinophil counts. Infection significantly altered these parameters in the low protein groups, i.e. the pathophysiological consequences of infection were more severe in the PEM pigs. These results demonstrate that reduced protein in the diet leads to malnourishment of both the host pigs and T. suis, and compromises the pig's ability to resist infection by T. suis and A. suum.
