SEASONAL VARIATPON AND PREVALENCE OF LUNGWORM INFECTIION IN THREE DIFFERNRT BREEDS OF PIGS SLAUGHSTERED AT BODIJA MUINICIPAL GOVERNMENT ABATTOIR, IBADAN, NIGERIIA.

Abstract

523 lung specimens were collected from three different pigs breeds (local, cross and exotic e.g. landrace, largewhite, etc) pig slaughtered at the Bodija Municipal Government Abattoir, Ibadan. This investigation was carried out within a period of seven months comprising the harmattan (January - March) and rainy (April - July) seasons. 523 pigs were slaughtered, 321 of the 523 pigs (61.38 %) had lungworms infection, while the remaining 202 pigs (38.62 %) were not infected. The infection rates among the three different breeds were 192 (59.81 %), 83 (25.86 %) and 46 (14.33 %) for local, cross and exotic, respectively. Likewise, the corresponding distribution patterns for Metastrongylus species i.e. Metastrongylus elongatus(Metastrongylus april); Metastrongylus pudendotectus; and Metastrongylus sudmi were 95.74,4.26 and 0% respectively. On the basis of higher infection rate, abundance of earthworms and greater abundance of Metastrongylus species, the local breed of pigs were the most susceptible.
