GASTRO INTESTINAL PARASITES OF PIGS IN SOUTHERN NIGERIA
Keywords:Pigs, fecal samples, intestinal parasites, productivity
Three hundred and twenty-nine fresh fecal samples collected from 15 swine herds in South Western Nigeria were examined microscopically for gastro intestinal parasites after centrifugal floatation in sugar solution.
Data analyses revealed that the large intestinal roundworm (Ascaris suum) was the most widespread species (100% of farms) followed by the strongyles (80%), coccidla (80%) and Trichuris suis (67%). Out of the 329 pigs sampled, 52.6% were infected with Ascaris suum, 37.4% with strongyles and 27.1% with coccidian. Trichuris suis was observed in 26.7% of the samples.
Adults appeared to be the most heavily parasitized group and could be a major source of infection for the young. The coccidian which have hitherto been overlooked as important pathogens could have a significant impact on productivity in pigs.
