Prevalence Of Metastrongylosis In Slaughtered Pigs In Eruwa And Ibadan, Oyo State, Nigeria

A total of 137 pigs were screened in Ibadan and Eruwa communities in Oyo State, Nigeria, for serum antibodies to Metastrongylus species using the Enzyme Linked Immunosorbent Assay method. An overall prevalence of 94.8% was observed among the pig population with 99.1% prevalence recorded in pigs slaughtered in Bodija Abattoir, Ibadan and 73% in pigs from commercial piggeries in Eruwa. A relatively higher prevalence of 100% was also observed in the wet season compared to 86% observed in the dry season among the pigs sampled. This disparity was attributed to the prevalence of earthworms in the wet season. The higher prevalence in pigs slaughtered in Ibadan could be attributed to the semi-intensive/extensive husbandry system of management under which the animals were kept compared to the pigs from Eruwa, which were kept under intensive management system. Au total, 137 porcs ont ete examines aupres des communautes d'Ibadan et d'Eruwa dans l'Etat de l'Oyo au Nigeria pour rechercher, dans le serum, des anticorps a l'espece Metastrongylus a l'aide de la technique ELISA (Titrage avec immunoadsorbant lie a une enzyme). On a note une prevalence globale de 94,8% dans la population porcine, avec une prevalence de 99,1% enregistree chez les porcs abattus a l'abattoir de Bodija a Ibadan et 73% chez les porcs des porcheries commerciales a Eruwa. Une prevalence relativement plus forte de 100% a egalement ete constatee durant la saison des pluies, compare a 86% pendant la saison seche chez les porcs selectionnes. L'ecart etait du a la prevalence des vers de terre pendant la saison des pluies. La prevalence plus forte chez les porcs abattus a Ibadan pourrait etre imputable au systeme d'exploitation semi-intensif/extensif sous lequel les animaux etaient maintenus par rapport aux porcs d'Eruwa, qui etaient soumis a un systeme d'exploitation intensif.
