A survey of gastrointestinal parasites in pigs of the Plateau and Rivers States, Nigeria

Abstract

Faecal samples were collected from a total of 1 000 pigs from the Port Harcourt and Jos areas of the Rivers and Plateau States, respectively, between January 1987 and March 1988. In the Jos area the parasite incidence was: Ascaris suum 53.1 %, Trichuris suis 8.5 %, Hyostrongylus rubidus 13.1 %, Metastrongylus salmi 3.7 %, Strongyloides ransomi 87.7 %, Oesophagostomum dentatum 35.1 % and Eimeria spp. 2.4 % while in Port Harcourt the incidence rate was Ascaris suum10.4 %, Trichuris suis 47.2 %, Oesophagostomum dentatum 50 %,Hyostrongylus rubidus 2 %, Ancylostoma duodenale 83.2 % and Eimeria spp. 3.6 %. The high rate of parasitic infections was due to poor management practices as shown by poor sanitary conditions. Access to human faeces, poor feeding and lack of deworming were also very evident. The different rates in the incidence of parasites in Jos and Port Harcourt areas were due to the varying moisture conditions in these states.
