Abstract

WWhole blood, faecal and bile samples were collected from three breeds of 160 cattle of both sexes slaughtered at the Bodija Ibadan abattoir between the months of December 2014 and October 2015, spanning two seasons. The study was aimed at investigating haematologic profile, seasonal, breed and sex prevalence of ruminant nematodes, fasciolosis and dicrocoelosis among the cattle sampled. The haematologic profile was determined using pocH-100iV DiffR (Haematology System, Sysmex Animal Health Germany). Modified McMaster slide technique was used to quantify the nematodes. The contents of the gall bladders were examined for the presence of the eggs of Fasciola and Dicroceolium species using sedimentation technique. Data obtained from the study was statistically analyzed using Chi-square test and Student’s t-test. The overall prevalence of the gastrointestinal nematodes (GI) was 31.88% while the mean egg per gram of faeces (EPG) count was 440.91±387.19. Prevalence of GI nematodes during the dry season was 28.21% while during the wet season it was 35.37%. There was a significant association (χ2 =7.12, P
